Description

Technical Field

[0001] The present invention relates to a method for controlling irrigation water flow for environmental protection and landscaping, a high-performance anti-fouling swing sprinkler and a water-saving method, an electromagnetic flowmeter and a circuit of a new energy-saving impeller suspension shaftless bracket for energy-saving agriculture and forestry irrigation, and a water-saving method, and also relates to a flow-adjustable dripper, a 360-degree nozzle, a joint with fine-tunable threaded ring size and pitch, and a combination of an energy-saving sprinkler timer and a water distributor with a multi-purpose interface, with the focus on an innovative remotely controllable spring timer with reference to an improved two-way valve with timing that automatically adjusts water pressure. Background Art

[0002] The desire to pursue environmental protection and gardening is endless; there are also many patents on the control method of irrigation water flow and the patent of the garden sprinkler timer switch with long axis and two sides control, such as patent US7252113B2 and patent ZL200820120164.8, both of which use the garden sprinkler timer switch with long axis and two sides control. Although the mechanical timer has a wide range of uses due to its strong structure, strong weather resistance, reliable use, and excellent cost performance, the two ends of the double gear shaft (11) are respectively mounted in the two oblong holes of the mechanical timer frame, and only one end has an auxiliary spring, while the other end does not have an auxiliary spring, lacking the proper balancing torque, so when twisting and running, the double gear shaft (11) and the meshing main gear shaft (15) cannot be parallel, and there is a potential hidden danger of long-term operation wear resistance and stability. Furthermore, due to structural problems, the main control valve and the pilot valve are arranged on one side of the main channel, and the mechanical timer is arranged on the other side of the main channel, causing the mechanical timer to be far away from the main control valve and the pilot valve that it should directly control, and has to be remotely pushed out with a very long stainless steel rod, which not only creates higher requirements for the precision of manufacturing tolerance matching, but also causes the possibility of occasional Euler instability of the pressure rod during long-term use; it also causes the stainless steel rod to be exposed and pass through the main channel, which is prone to rust and adhesion over time and hinders the movement; in addition, the stainless steel rod passing through the main channel also has a problem of sealing and leakage over time. Furthermore, the scheme of arranging the main control valve and the pilot valve on one side of the main channel and arranging the mechanical timer on the other side of the main channel is based on the conventional idea that the remote main control valve, the pilot valve and the main channel are immovable relative to the main body of the mechanical timer. Therefore, the remote main control valve, the pilot valve and the main channel are connected to the main body of the mechanical timer by a larger housing, resulting in a larger appearance of the garden sprinkler timing switch; at the same time, in addition to the thin shaft of the main gear shaft (15) that plays a controlling role of the mechanical timer, a large rotating gradient circle and several parts have to be used for rotation and control, that is, the multiple parts make some aspects of the rotating gradient circle, such as the plastic square hole in the middle, subject to lateral deflection torque, causing the gradient circle disk surface to be skewed and affecting the effect.In summary, this type of clock and watch products can be further improved, improved and integrated, and then supplemented with innovation to make the products reach a higher level; but even if the timer and sprinkler are easy to use, it will not work if the interface is not good; in practice, some are pipe interfaces, and some are faucets without threads. The method of adding multiple interfaces has been used, which is OK for faucets and some interfaces, but not for many interfaces; the reason is that many interfaces in a garden have been worn or rusted, and the threads of many interfaces have been loose, and they cannot be connected or connected tightly, and they leak after being connected. The threads of many interfaces are similar but different. The threads are mixed together; it is not easy to replace a large number of interfaces; even if they are replaced, many threads on the original water pipes have loose teeth, and the replaced interfaces will also be worn or rusted, and the new interfaces also have many problems such as upper tolerance or lower tolerance and over-tolerance, and cannot be connected or cannot be connected tightly and have loose teeth; there is also the problem that it is slow to use hand tools to twist a small half circle and then change hands to twist a small half circle many times to complete a thread; whether it is used for sprinkler timers and irrigation water distributors or other, it is hoped that there will be a connector that can fine-tune the size and pitch of the thread ring so that it is widely applicable and can be connected quickly. There are many patents for water-saving sprinkler irrigation and drip irrigation, such as CN103651053A and 012055360, etc., each with its own advantages. Existing products are numerous and imperfect; the water spraying of another nozzle that has been tried for preliminary improvement still has shortcomings, and the water spraying range is only half of the side, and there is no 360-degree irrigation effect. The regulation of drip irrigation water output, the regulation of irrigation water according to plant growth requirements, and the efficient water-saving irrigation that saves water resources are long-standing problems in the industry at home and abroad. It is necessary to improve the water-saving method of new flow-adjustable drippers, especially the water-saving method of new energy-saving electromagnetic flowmeters for agricultural and forestry irrigation. At present, electromagnetic flowmeters are widely used in various industrial fields, and their function is to measure the instantaneous flow of various fluids. The existing electromagnetic flowmeter is made based on the electromagnetic induction law of Faraday principle. When the conductor cuts the magnetic lines of force in the magnetic field, an induced potential proportional to the liquid flow rate is generated and detected by the electrode in contact with the liquid. Then, after being converted into intelligent processing through the cable, the flow data can be communicated and controlled with the computer. The existing electromagnetic flowmeter includes a measuring tube, an inlet flange, an outlet flange, an electrode, an excitation coil, a measuring tube shell, a circuit board and a display device. Among them, the measuring tube, the inlet flange, the outlet flange and the measuring tube shell are all made of metal materials. The disadvantages of using metal materials are: the entire flowmeter is heavy, and it is inconvenient to install and maintain. It usually requires the cooperation of multiple people, which affects the work efficiency; and the cost of metal materials is high, making the price of the finished flowmeter more expensive; how to prevent the sprinkler head from fouling is also a long-standing problem. The market not only needs a swing sprinkler with adjustable spraying angle, but also needs an improved timing valve for automatically adjusting water pressure, in order to solve the long-standing problem that the pilot overflow of adjusting water pressure often fails and is unreliable. Therefore, it is necessary to improve and innovate the existing products.The improved timing valve for automatic water pressure regulation is not an ordinary two-way valve with a simple valve plate switch, nor is it different from the conventional self-operated pressure regulating valve with a pilot and a needle valve. Instead, it is a valve with a logarithmic spiral function curve, a logarithmic pilot screw core with an extruded arrow section, and a one-way damping bend. It is used not only for drip irrigation but also for high-end. However, there are always improvements. The improvements of the improved self-adjusting water pressure remote control timing are: first, a timing device is added to automatically adjust the water pressure more accurately; second, the one-way ball is improved to a one-way logarithmic spiral cone core with a similar logarithmic spiral and the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, which is beneficial to the one-way damping valve. Because there is a small amount of overflow at the top of the spiral cone core to go to the damping circuit, it is not easy to get stuck, thereby solving the long-standing problem of occasional failure; and third, the filtering and epidemic prevention measures are further improved. Fourth, the straight sides of the logarithmic pilot screw head convex right side (18d) and the logarithmic pilot screw head convex left side (18c) of the logarithmic pilot screw head (18) are improved to curved sides, and their side contours are similar to the logarithmic spiral to obtain the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, so that the improved logarithmic pilot screw groove (19) has a further impeller effect under fluid pressure and better provides power for micro-rotation. The market needs not only a swaying sprinkler with adjustable spraying angle, but also an improved and innovative remotely controllable spring timer, so as to create a series of various products including a two-way valve and a sprinkler and a connector that are newly equipped with automatic water pressure regulation. Summary of the invention

[0003] The market needs not only swing sprinklers with adjustable spray angles, but also improved and innovative two-way valves that automatically adjust water pressure, in order to solve the long-standing problem that the pilot overflow for adjusting water pressure often fails and is unreliable. It is necessary to improve and innovate existing products. The invention innovates a remotely controllable valve core timer, which is not an ordinary two-way valve with a simple valve plate switch, nor is it different from a conventional self-acting pressure regulating valve with a pilot and a needle valve. Instead, it is a valve with a logarithmic spiral function curve, a logarithmic pilot spiral core with an extruded arrow section, and a one-way damping bend, which is not only used for drip irrigation, but also can be used for high-end. However, the improvement is continuous. The improvements of the improved remotely controllable spring timer are as follows: first, a setting time device is added to automatically adjust the water pressure more accurately; second, the one-way ball is improved to a one-way logarithmic spiral cone core with a similar logarithmic spiral and the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, which is beneficial to the one-way damping valve. Because there is a small amount of overflow at the top of the spiral cone core to go to the damping circuit, it is not easy to get stuck, thereby solving the long-standing problem of occasional failure; and third, the filtering and epidemic prevention measures are further improved. Fourth, the straight sides of the logarithmic pilot screw head convex right side (18d) and the logarithmic pilot screw head convex left side (18c) of the logarithmic pilot screw head (18) are improved to curved sides, and their side contours are similar to the logarithmic spiral to obtain the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, so as to improve the logarithmic pilot screw groove (19) to have an impeller effect under fluid pressure and provide power for micro-rotation. A two-way valve for automatically adjusting water pressure using a remotely controlled spring timer comprises a logarithmic pilot screw core (1), a pilot diaphragm (2), a pilot return spring (3), a pre-adjusting pressure spring (4), a pre-adjusting pressure column (5), a pressure regulating disc (6), a pilot auxiliary spring (7), a one-way damping ball (8), a one-way damping bend (9), a filter diaphragm (10), a filter noise reduction core (11), a valve switch (12), a rotating core notch (12a), a switch pull groove (12c), a valve outlet (14), a valve inlet (15), a valve body (16), a logarithmic pilot screw body (17), a logarithmic pilot screw head (18), a logarithmic pilot screw head concave on the right side (18a), a logarithmic pilot screw head concave on the left side (18b), a logarithmic pilot screw The two-way valve with a convex head on the right (18d), a convex logarithmic pilot screw head on the left (18c), a logarithmic pilot screw groove (19), and a logarithmic pilot screw core groove (20) is a timed automatic water pressure regulating two-way valve. The highlight is that the logarithmic pilot screw core (1) is two symmetrical logarithmic pilot screw bodies (17) movably arranged in the transverse channels between the two valve outlets (14) and the valve inlet (15) of the valve, the inner contour of the channel of the logarithmic pilot screw body (17) is approximately similar to a section of a logarithmic spiral, and the outer contour of the logarithmic pilot screw core (1) movably installed therein is also approximately similar to a section of a logarithmic spiral, so as to utilize the characteristic that the pressure angle of the logarithmic spiral is equal everywhere.The rear guide core of the logarithmic pilot spiral core (1) is moved backward and is provided with the pilot diaphragm (2), the pilot return spring (3), the pre-adjusting pressure spring (4), the pre-adjusting pressure column (5), and the pressure regulating disc (6), so that the pressure regulating thread on the pressure regulating disc (6) is rotated through the thread provided on the valve body (16) so that the disc contacts the pre-adjusting pressure column (5) to expand and contract the pre-adjusting pressure spring (4) to pre-adjust the pressure. The rear guide core of the logarithmic pilot spiral core (1) contacts the pilot diaphragm (2) and affects the pilot return spring (3), and together with the pilot auxiliary spring (7) provided at the front of the logarithmic pilot spiral core (1), affects and maintains a pressure regulating balance and mutual pulsation of the logarithmic pilot spiral core (1); the valve body (16) of the valve A one-way damping bend (9) is provided beside the logarithmic pilot screw body (17) in the transverse channel so as to connect the outlet cavity in front of the valve outlet (14) and the inlet cavity behind the valve inlet (15); the one-way damping ball (8) containing a one-way valve spring is provided at the passage of the one-way damping bend (9) close to the inlet cavity behind the valve inlet (15) so as to form a high-efficiency damping circuit with a one-way valve and a damping bend; the filter membrane (10) and the filter noise reduction core (11) are provided in front of the inlet cavity behind the valve inlet (15) for filtering; the valve body (16) is matched with the two valve switches (12), the rotating core notch (12a) and the switch pull groove (12c) so as to open and close the valve inlet (15). The cross section of the logarithmic pilot screw head (18) movably mounted in the logarithmic pilot screw body (17) of the valve body (16) is provided with the logarithmic pilot screw head concave right side (18a), the logarithmic pilot screw head concave left side (18b), the logarithmic pilot screw head convex right side (18d), and the logarithmic pilot screw head convex left side (18c). The logarithmic pilot screw head concave right side (18a) and the logarithmic pilot screw head concave left side (18b) cooperate with each other to form a concave shape. After spiral scanning, it becomes a logarithmic pilot screw core groove (20) with the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, so as to perform piloting and clearance micro-motion with the logarithmic pilot screw body (17) of the valve body (16). and micro-rotation, the logarithmic pilot screw head (18) also forms another logarithmic pilot screw groove (19) with the characteristic of equal pressure angle of the logarithmic screw after spiral scanning, so as to facilitate the impeller to provide power for micro-rotation under fluid pressure, and the logarithmic pilot screw groove (19) and the logarithmic pilot screw core groove (20) each have a wonderful use; the logarithmic pilot screw core (1) is flexible and elastic, and the screw groove and the groove have extrusion creeping during movement, which is conducive to pressure regulation; the improved remotely controllable valve core timer has the following improvements: first, a setting time device is added to automatically adjust the water pressure more accurately, and second, the one-way ball is improved to a one-way logarithmic spiral cone core with the characteristic of equal pressure angle of the logarithmic screw, which is similar to the logarithmic spiral.The invention is beneficial to the one-way damping valve, because there is a small amount of overflow at the top of the spiral cone core to the damping circuit, so that it is not easy to get stuck, thereby solving the long-standing problem of occasional failure, and thirdly, further improving the filtering and epidemic prevention measures; and fourthly, the straight sides of the logarithmic pilot screw head convex right side (18d) and the logarithmic pilot screw head convex left side (18c) of the logarithmic pilot screw head (18) are respectively curved sides, and their side profiles are approximately similar to the logarithmic spiral to obtain the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, so as to facilitate the improved logarithmic pilot screw groove (19) to have a further impeller effect under fluid pressure and better provide power for micro-rotation; the first scheme of the two-way valve for automatically adjusting water pressure and the second scheme of the improved automatic water pressure regulating valve The two-way valves have their own advantages and complement each other. They have different uses in different occasions. The former is mostly used for drip irrigation, while the latter is mostly used for timing and precision. The main control valve soft core (21) of the timing device is installed inside the timing body (22). It forms a de facto main control valve with the valve cover, the main control valve soft core compression spring (32) and the small chamber I (22b) inside the timing body (22). The small chamber inside the main control valve and the small chamber inside the pilot valve are connected by a narrow gap. The damping can make it open when the pressure is lost, ensuring that the switch does not fail occasionally, so as to save energy and water in time. Since the main control valve soft core is soft, it is closed when there is no pressure loss under the cooperation of the main control valve soft core compression spring (32) to implement the timing of water blocking, When the pressure is lost, it is opened to implement water flow; when the soft plug (d18) moves up, the actual pilot valve is opened, and because there is a gap between the small chamber I (22b) inside the timing body (22) and the small chamber II (22c) inside the timing body (22) that forms the actual pilot valve, the pressure change is transmitted, and the pressure in the small chamber II (22c) inside the timing body (22) can be lost, so that the main control valve soft core compression spring (32) opens, and the incoming water flows into the upper channel (22a) and the lower channel (22d) of the timing body (22) through the timing inlet (d15) and the copper ion filter cover (d15g), and the water is implemented to the valve inlet (15); when the operator manually After the timing switch cover is turned half a circle in the positive direction, the spring makes the timing device operate, and the water supply pipeline is opened at the same time; when the timer is in place, the hook-shaped pilot valve core (d1) falls into the L-shaped recessed part (1b) provided on the circumference of the timing lower seat, and the hook-shaped pilot valve core (d1) is closed, because there is a narrow gap between the internal small chamber I (22b) and the internal small chamber II (22c) to ensure that there is no pressure loss, and because the main control valve soft core is soft, preferably with a Shore hardness of 70 degrees, under the cooperation of the main control valve soft core compression spring (32), the timer switch is closed through the main control valve soft core and the main control valve soft core compression spring (32) when there is no pressure loss, and the timing is implemented without water flow. ,

[0004] A remotely controllable spring timer is characterized in that a remote control electrical box (41) and an electromagnetic pilot valve having an electromagnetic coil (21m) are arranged on a remote timing body (22c), a hollow solenoid (21m2) is arranged inside the electromagnetic coil (21m), the middle part of the hollow solenoid passes through an electromagnetic core (21n) to operate the electromagnetic pilot valve, and a circuit board of the remote control electrical box (41) is provided with a receiving circuit and a time base circuit to receive a sub-ultrasonic remote control of a passive airbag transmitter; sometimes it is not convenient to turn on and off by toggling a switch, and a general remote control device requires people to hold the remote control device in their hands. It is not very convenient to have a remote control, so a toy-style modified airbag is used here, using 18kHz sound waves as remote control signals. The hearing range of the human ear is Hz-20kHz, and above 20kHz is ultrasonic wave that is inaudible to the human ear. Although the 18kHz sound wave is within the audible sound wave range, it is at the high end edge of the audible sound wave and is close to the lowest frequency of ultrasonic wave. The human ear is already very insensitive to it and can only hear slight sub-sounds. Therefore, this sound wave is called sub-ultrasonic wave. Using this sound wave as a remote control command will not affect and interfere with the lives of others. This transmitter is passive. When using it, you only need to pinch the launching airbag with your hand to remotely control it.

[0005] Many products have multiple modifications, deformations and adaptabilities that require continuous improvement and perfection.

[0006] The modified airbag is slightly modified on the basis of the existing airbag and air whistle of the toy airbag on the market. A parabolic small opening (41p2) shaped like a drop of water is opened behind the original air whistle mouth (41p) to facilitate the harmonic effect; the transmitter is a rubber ball compressed air tongue-shaped sound whistle with a parabolic small opening (41p2). When the rubber airbag is pinched by hand, a pulse airflow of a certain pressure is input into the whistle body through the air opening. When the airflow passes through the narrow slit, it is quickly ejected and impacts the air whistle mouth. At the same time, with the cooperation of the parabolic small opening, cavity resonance is generated, and sound waves are radiated outward from the wedge of the logarithmic spiral of the air whistle mouth to control the receiving circuit provided on the circuit board of the remote control electrical box (41) to receive the sub-ultrasonic sound of the passive airbag transmitter. The remote control of the remote control system forms an electronic timer capable of remote sub-supersonic control so as to cooperate with various valves and joints of appliances; the remote control programmable timer is characterized in that a control circuit having a receiving sound wave transducer B, a frequency-selective amplifier VT1 and a sound-controlled integrated circuit A is provided on the remote control electrical box (41) provided on the remote timing body (22c), so as to link the hollow solenoid (21m2) provided in the electromagnetic coil (21m) through the time delay contact K1 of the time relay K to attract the electromagnetic iron core (21n) of the electromagnetic pilot valve to operate the modified valve soft core (21a) of the main control valve soft core (21) of the electromagnetic pilot valve; the receiving sound wave transducer B is a parallel station containing an aluminum-plated polyester film MP and a piezoelectric ceramic sheet. The polar body capacitor element is modified, and the way to match its resonance point with the transmitter is to use a suitable capacitor produced in batches to make its resonance frequency conform to the radiated sound wave frequency 18KHZ of the transmitter. The second way is that the modified airbag is slightly modified, and a parabolic small opening (41p2) shaped like a drop of water is opened behind the original air flute mouth (41p), and the same tool, the same machine model and the same contour trajectory are used to achieve consistency to improve sensitivity and benefit the harmonic effect; the transmitter is a compressed air tongue-shaped sound flute with a rubber ball having a parabolic small opening (41p2). When the rubber airbag is pinched by hand, a pulse airflow of a certain pressure is input into the flute body through the air opening, and the airflow is quickly ejected when passing through the narrow slit, impacting the air flute mouth and at the same time, under the cooperation of the parabolic small opening , generating cavity resonance, and radiating sound waves outward from the wedge of the logarithmic spiral of the air whistle mouth to control the receiving circuit and timing circuit provided on the circuit board of the remote control electrical box (41) to receive the sub-ultrasonic remote control timing of the modified passive airbag transmitter to form a remotely controllable programmable timer; after receiving the sub-ultrasonic signal of the frequency of 18KHZ, the sound wave transducer B outputs the corresponding electrical signal, which is directly sent to the base of the frequency selective amplifier VT1 for amplification; the inductor L3 and the frequency selective capacitor C3 form a frequency selective network, which resonates at the frequency of 18KHZ, so only the control signal of 18KHZ can be output from the collector through the trigger capacitor C4 to trigger the voice control integrated circuit A to work, so it can effectively eliminate the interference of the clutter signal to the circuit.

[0007] We made continuous improvements, first changing the circuit, then the valve core, and then the plug spring. We found that the skewed spring blocking the pilot port was one of the causes of occasional failure.

[0008] like Fig.14 As shown, the valve core timer which can be remotely controlled is provided with a control circuit having a sound wave transducer B and a sound control integrated circuit A. The hollow solenoid (21m2) provided in the electromagnetic coil (21m) is controlled by a programming timer A2 to attract the electromagnetic iron core (21n) to operate the modified valve soft core (21a) to control the valve water flow in a timely manner. The characteristic is that the model (CD4541) of the programming timer A2 provided therein is a CMOS programmable timing integrated circuit. When the values ​​of the external potentiometer RP2 and the capacitor C7 are determined, the valve core timer A2 is controlled by a programming timer A2. After the determination, the oscillation frequency of the internal oscillator is determined; the timing time of the circuit can be estimated by the well-known formula t = 2.3nR (RP2) * C6, where n is the timing coefficient, and the timing coefficient of this circuit is 32768; the potentiometer RP2 is 470k and the capacitor C7 is 1μ; in order to use a large flow valve and a high-power electromagnetic coil (21m), 220V AC is specially selected, and the 220V AC is stepped down by the capacitor C1 of 0.68μ, the bypass resistor R20 is bypassed by 1M, the silicon rectifier diode VD is rectified, and the voltage regulator diode VS After voltage stabilization, a 12V DC voltage can be obtained at the capacitor C1, which is used by the control circuit of the sound wave transducer B and the voice control integrated circuit A. When the 12th pin of the control circuit of the sound wave transducer B and the voice control integrated circuit A outputs a high level, the programming timer A2 starts timing. Because the timing time has not arrived, its output terminal 8 is a low level, the silicon transistor VT is cut off, and its collector outputs a high level, that is, the control electrode of the thyristor VTH can be turned on by obtaining a positive trigger current through R9 of 560, so as to control the electromagnetic coil (21m). Some hollow solenoids (21m2) attract the electromagnetic core (21n) to operate the modified valve soft core (21a) to control the valve in a timed manner so that water flows through; when the timing time is reached, the output of the 8th pin of A2 is high level, the silicon transistor VT is turned on, and its collector outputs low level, the control electrode of the thyristor VTH loses the trigger current, and when the alternating current passes through zero, it is turned off, and the electromagnetic core (21n) is not attracted to operate the modified valve soft core (21a), and the timed control valve does not allow water to flow through; the capacitor C7 uses a high-precision tantalum capacitor to achieve accurate timing.

[0009] The innovative solution of the present invention to solve the technical problem is:

[0010] After continuous improvements, first changing the circuit, then the valve core, and then the insert spring, we discovered that the skewed spring blocking the pilot port was one of the causes of occasional failure. Solving the problem of occasional failure is an international and long-standing problem.

[0011] Further improvement, the remotely controlled spring timer is provided with a control circuit having a sound wave transducer B and a sound control integrated circuit A, and the hollow solenoid (21m2) provided in the electromagnetic coil (21m) is controlled by the programming timer A2 to attract the electromagnetic iron core (21n) to operate the modified valve soft core (21a) to control the valve water flow in a timely manner. The model (CD4541) of the programming timer A2 provided therein is a CMOS programmable timing integrated circuit. When the values ​​of the external potentiometer RP2 and the capacitor C7 are determined, the oscillation frequency of the internal oscillator is determined; and in order to cooperate with watering, not only the timing is required The modified valve core (21a) is provided with a valve core socket (21t2) and a valve core flap (21t3); the valve core socket (21t2) is arranged in a concave trough close to the edge of the disk where the spring is placed, and the cross section of the modified valve core (21a) is a disk surrounded by a cosine function curve. The valve core socket (21t2) is a through hole. But it is not a round hole. The valve core socket (21t2) is a multi-petal multi-wave pilot valve hole. Even when the circular cross-section of the installed spring is inserted, there is a tiny gap so that the hole is not sealed and still has a pilot effect; the valve core petal (21t3) provided on the modified valve core (21a) is arranged on the high peak at the center of the disk whose cross-section is a disk surrounded by a cosine function curve. The center of the valve core petal (21t3) is provided with a soft core petal with four bosses and four fan-shaped petal grooves to facilitate the matching of the valve stem and the soft core petal of the electromagnetic core (21n), so that the modified valve core is more enhanced. The said remotely controllable spring timer is provided with a control circuit having a sound wave transducer B and a sound control integrated circuit A, and the programming timer A2 is used to control the hollow solenoid (21m2) provided in the electromagnetic coil (21m) to attract the electromagnetic iron core (21n) to manipulate the pilot valve port composed of the modified valve soft core (21a) and the pin spring (21b) to control the valve water flow in a timely manner, characterized in that the pin spring (21b) is a compression coil spring with four turns, and the upper and lower ends are tightly connected, the lower end is tightened and then ground, the upper end is as flat as possible, and the upper end is bent and extended downward by 1.5 times the length of the spiral tube of the natural spiral spring to form the plug pin (21s); the plug pin (21s) is subjected to carbon-nitrogen-boron three-element co-diffusion heat treatment, and is placed in a mixture of borax, carbon powder and urea at 723 degrees until the plug pin is silvery white in appearance, so as to be strong on the outside and soft on the inside and resistant to corrosion; the plug pin (21s) is inserted into the valve core socket (21t2) on the modified valve core (21a), and there will be a slight gap between the two in any case to play a leading role; the lower end of the plug pin spring (21b) is tightened and then ground flat, so that it is easy to fit in the concave trough of the placement spring near the edge of the disk of the modified valve core (21a), which is a disk surrounded by a cosine function curve, which is beneficial to the tacit cooperation between the plug pin spring (21b) and the modified valve core (21a), thereby improving the quality and grade of the remotely controlled plug spring timer. .

[0111] The invention relates to a valve core timer which can be controlled remotely and can use a toy-type modified air bag as a transmitter.

[0112] This innovation is not only used for drip irrigation but also for high-end applications; it can be used independently or in conjunction with other devices.

[0113] An electronic timer capable of remote sub-supersonic control is different from conventional ones. Its highlight is that the first logarithmic pilot screw core (1) is symmetrical and has two logarithmic pilot screw bodies (17) movably arranged in the transverse channel between the two valve outlets (14) and the valve inlet (15) of the valve. The inner contour of the channel of the logarithmic pilot screw body (17) is approximately similar to a section of a logarithmic spiral, and the outer contour of the logarithmic pilot screw core (1) movably arranged therein is also approximately similar to a section of a logarithmic spiral. In order to utilize the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, the rear guide core of the logarithmic pilot spiral core (1) is moved back and provided with the pilot diaphragm (2), the pilot return spring (3), the pre-adjusting pressure spring (4), the pre-adjusting pressure column (5), and the pressure regulating disc (6), so that the pressure regulating thread on the pressure regulating disc (6) is rotated through the thread provided on the valve body (16) so that the disc contacts the pre-adjusting pressure column (5) to expand and contract the pre-adjusting pressure spring (4) to pre-adjust the pressure, and the rear of the logarithmic pilot spiral core (1) is The rear part of the guide core contacts the pilot diaphragm (2) and affects the pilot return spring (3), and together with the pilot auxiliary spring (7) arranged at the front part of the logarithmic pilot spiral core (1), affects and maintains a pressure adjustment balance and mutual pulsation of the logarithmic pilot spiral core (1); a one-way damping bend (9) is provided next to the logarithmic pilot spiral body (17) in the transverse channel of the valve body (16) of the valve so as to connect the outlet cavity in front of the valve outlet (14) and the inlet cavity behind the valve inlet (15). The one-way damping bend (9) The one-way damping ball (8) containing a one-way valve spring is arranged at the entrance of the damping curve (9) near the rear entrance of the valve inlet (15) to form a high-efficiency damping circuit with a one-way valve and a damping curve; the filter membrane (10) and the filter noise reduction core (11) are arranged in front of the entrance of the rear entrance of the valve inlet (15) for filtering; the valve body (16) is matched with the two valve switches (12), the rotating core notch (12a) and the switch pull groove (12c) for switching;The logarithmic pilot screw head (18) movably installed in the logarithmic pilot screw body (17) of the valve body (16) is provided with the logarithmic pilot screw head concave right side (18a), the logarithmic pilot screw head concave left side (18b), the logarithmic pilot screw head convex right side (18d), and the logarithmic pilot screw head convex left side (18c) on the cross section. The logarithmic pilot screw head concave right side (18a) and the logarithmic pilot screw head concave left side (18b) cooperate with each other to form a concave shape. After spiral scanning, it becomes a logarithmic pilot screw core groove (20) with the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, so as to cooperate with the logarithmic pilot screw body (17) of the valve body (16) for piloting and clearance movement and micro movement. Micro-rotation, the logarithmic pilot screw head (18) also forms another logarithmic pilot screw groove (19) with the characteristic of equal pressure angle of the logarithmic screw after spiral scanning, which is conducive to the impeller effect under fluid pressure to provide power for micro-rotation, and the logarithmic pilot screw groove (19) and the logarithmic pilot screw core groove (20) each have a wonderful use; the logarithmic pilot screw core (1) is flexible and elastic, and the screw groove and the groove have extrusion creep during movement, which is conducive to pressure regulation; the benefit is that it overcomes the inability of conventional two-way to regulate pressure and solves the long-standing problem of the conventional double-pressure regulating valve that the valve core is stuck and occasionally fails due to scale and debris, and the damping hole is blocked. Because the valve core can move and rotate, it is not easy to get stuck. ;

[0114] The electronic timer capable of remote sub-supercontrol has the following characteristics: first, a time setting device is added to automatically adjust the water pressure more accurately; second, the one-way ball is improved to be a one-way logarithmic spiral cone core with a similar logarithmic spiral and the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, which is beneficial to the one-way damping valve. Because there is a small amount of overflow at the top of the spiral cone core to go to the damping circuit, it is not easy to get stuck, thereby solving the long-standing problem of occasional failure; and third, the filtering and epidemic prevention measures are further improved; and fourth, the straight sides of the logarithmic pilot screw head convex right side (18d) and the logarithmic pilot screw head convex left side (18c) of the logarithmic pilot screw head (18) are improved to be curved sides, and their side contours are similar to the logarithmic spiral to obtain the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, so as to facilitate the improved logarithmic pilot screw groove (19) Under fluid pressure, there is a further impeller effect to better provide power for micro-rotation; the two-way valve for automatic water pressure regulation of the first scheme and the improved two-way valve for automatic water pressure regulation of the second scheme have their own advantages and complement each other, and have their own uses in different occasions; the former is mostly used for drip irrigation, and the latter is mostly used for timing and precision; the main control valve soft core of the timing device is installed inside the timing body (22), and it forms a de facto main control valve with the valve cover and the main control valve soft core compression spring (32), and the small chamber I (22b) inside the timing body (22). The small chamber inside the main control valve and the small chamber inside the pilot valve are connected by a narrow gap, and there is a damping that can cause it to lose pressure and open, ensuring that the switch does not fail occasionally, so as to save energy and water during timing; due to the main control valve The valve core is soft. Under the cooperation of the main control valve core compression spring (32), it is closed when there is no pressure loss to implement timing water blocking, and is opened when there is pressure loss to implement water flow. When the soft plug (d18) moves upward, the actual pilot valve is opened. Since there is a gap between the small chamber I (22b) inside the timing body (22) and the small chamber II (22c) inside the timing body (22) forming the actual pilot valve, the pressure change is transmitted. The small chamber II (22c) inside the timing body (22) can lose pressure, so that the main control valve core compression spring (32) opens, and the incoming water flows into the upper channel (22a) and the lower channel (22d) of the timing body (22) through the timing inlet (d15) and the copper ion filter cover (d15g), and the actual Water is passed to the valve inlet (15); when the operator manually turns the timing switch cover half a circle in the positive direction, the spring causes the timing device to operate, and the water supply pipeline is opened at the same time; when the timer is in place, the hook-shaped pilot valve core (d1) falls into the L-shaped recessed part (1b) provided on the circumference of the timing lower seat, and the hook-shaped pilot valve core (d1) is closed, because there is a narrow gap between the internal small chamber I (22b) and the internal small chamber II (22c) to ensure that there is no pressure loss, and because the main control valve soft core is soft with a Shore hardness of 70 degrees, under the cooperation of the main control valve soft core compression spring (32), the timer switch is closed by the main control valve soft core and the main control valve soft core compression spring (32) when there is no pressure loss, and the timing is implemented without water flow.

[0115] An electronic timer capable of remote sub-supersonic control, characterized in that the valve is provided with a timing device; an improved one-way ball plus one-way logarithmic spiral cone core having a similar logarithmic spiral with a characteristic that the pressure angle of the logarithmic spiral is equal everywhere, the top of which has a one-way ball head, the rear of which has a guide handle with an external spring, the two concave edges of the spiral scanning cross section of the one-way logarithmic spiral cone core close to the damping passage are the first concave arc edge (8a) and the second concave arc edge (8b), which is beneficial to the one-way damping valve The ball plus rotating core can rotate slightly and pulsate along the approximate logarithmic spiral groove to prevent static scaling and clogging; improved filtering and epidemic prevention measures , a copper ion filter cover (d15g) is provided to be combined with a filter membrane (10) and a filter noise reduction core (11) to form a triple filtering and epidemic prevention measure; it is also found that the soft core of the main control valve of the timing device is soft, preferably with a Shore hardness of seventy degrees; the straight edges of the logarithmic pilot screw head convex right side (18d) and the logarithmic pilot screw head convex left side (18c) of the improved logarithmic pilot screw head (18) are respectively curved edges, and their edge contours are approximately similar to the logarithmic spiral in order to obtain the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, so as to facilitate the improved logarithmic pilot screw groove (19) to have a further impeller effect under fluid pressure and better provide power for micro-rotation.

[0116] An electronic timer capable of remote sub-ultrasonic control is characterized in that a remote control electrical box (41) and an electromagnetic pilot valve with an electromagnetic coil (21m) are arranged on a remote timing body (22c), a hollow solenoid (21m2) is arranged inside the electromagnetic coil (21m), the middle part of the hollow solenoid is used to operate the electromagnetic pilot valve through a permanent magnet rod, and the circuit board of the remote control electrical box (41) is provided with a receiving circuit and a time base circuit to receive the sub-ultrasonic remote control of a passive airbag transmitter; sometimes it is felt that it is not convenient to turn on and off by toggling a switch, and a general remote control device requires people to hold a remote control in their hands, so it is also not convenient. Here, a toy-style modified airbag is used, and 18kHz sound waves are used as remote control signals. The hearing range of the human ear is Hz-20kHz, and those above 20kHz are ultrasonic waves that are inaudible to the human ear. Although the 18kHz sound wave is within the audible sound wave range, it is at the high end edge of the audible sound wave, close to the lowest frequency of ultrasonic waves, and the human ear is very insensitive to it, and can only hear a slight sound. The sound is very small, so this sound wave is called sub-ultrasonic wave. Using this sound wave as a remote control command will not affect or interfere with the lives of others. The transmitter is passive. When in use, you only need to pinch the launch airbag with your hand to remotely control it. The modified airbag is slightly modified on the basis of the existing airbag and air whistle of the toy airbag on the market. A parabolic small opening (41p2) shaped like a drop of water is opened behind the original air whistle mouth (41p) to facilitate the harmonic effect. The transmitter is a parabolic small opening (41p2) with a parabolic shape. p2) of a rubber ball compressed air tongue-shaped sound flute, when the rubber airbag is pinched by hand, a pulse airflow of a certain pressure is input into the flute body through the air port, and the airflow is rapidly ejected when passing through the narrow slit, impacting the air flute port and generating cavity resonance in cooperation with the parabolic small opening, and radiating sound waves outward from the wedge of the logarithmic spiral of the air flute port to control the receiving circuit and the time base circuit provided on the circuit board of the remote control electrical box (41), so as to receive the sub-ultrasonic remote control of the passive airbag transmitter and form an electronic timer capable of remote sub-ultrasonic control.

[0117] Benefits:

[0118] The electronic timer with remote sub-ultrasonic control uses a toy-style modified airbag and 18kHz sound waves as remote control signals, so this sound wave is called sub-ultrasonic. Using this sound wave as a remote control command will not affect or interfere with other people's lives. This transmitter is passive. When using it, you only need to pinch the launch airbag with your hand to remotely control the electromagnetic coil to control the pilot valve. It has the advantages of simple production, convenient adjustment and measurement, low cost, reliable performance, and no interference with other electrical appliances. There are many benefits in matching and comprehensive utilization: the market not only needs a swing sprinkler with adjustable spraying angle, but also needs an innovative two-way valve that automatically adjusts the water pressure, in order to solve the long-standing problem of unreliable failure of the pilot overflow to adjust the water pressure. It is necessary to improve and innovate existing products. The improved two-way valve for automatically regulating water pressure is not an ordinary two-way valve with a simple valve plate switch, nor is it different from a conventional self-operated pressure regulating valve with a pilot and a needle valve. Instead, it is a valve with a logarithmic spiral function curve, a logarithmic pilot spiral core with an extruded arrow section, and a one-way damping bend. It is not only used for drip irrigation but also can be used for high-end, timed, automatic water pressure regulating two-way valve. The highlight is that the logarithmic pilot spiral core (1) is two symmetrical ones, each of which is movably arranged at the two valve outlets ( In the logarithmic pilot screw body (17) in the transverse channel between the valve inlet (15) and the valve inlet (14), the inner contour of the channel of the logarithmic pilot screw body (17) is similar to a section of a logarithmic spiral, and the outer contour of the logarithmic pilot screw core (1) movably mounted therein is also similar to a section of a logarithmic spiral, so as to utilize the characteristic that the pressure angle of the logarithmic spiral is equal everywhere. The rear guide core of the logarithmic pilot screw core (1) is moved back and provided with the pilot diaphragm (2), the pilot return spring (3), and the pre-adjusting pressure spring. (4), the pre-pressure regulating column (5), and the pressure regulating dial (6), so that the pressure regulating thread on the pressure regulating dial (6) is rotated through the thread provided on the valve body (16) so that the dial contacts the pre-pressure regulating column (5) to expand and contract the pre-pressure regulating spring (4) to pre-regulate the pressure, and the rear guide core of the logarithmic pilot screw core (1) contacts the pilot diaphragm (2) and affects the pilot return spring (3) and together with the pilot auxiliary spring (7) provided at the front of the logarithmic pilot screw core (1), affects and maintains the logarithmic pilot screw core (1). A pressure regulating balance and mutual pulsation of the core (1); a one-way damping bend (9) is provided beside the logarithmic pilot screw (17) in the transverse channel of the valve body (16) of the valve so as to connect the outlet cavity in front of the valve outlet (14) and the inlet cavity behind the valve inlet (15); the one-way damping ball (8) containing a one-way valve spring is provided at the opening of the one-way damping bend (9) near the inlet cavity behind the valve inlet (15) so as to form a high-efficiency damping circuit with a one-way valve and a damping bend;The filter membrane (10) and the filter noise reduction core (11) are arranged in front of the inlet cavity behind the valve inlet (15) for filtering, and the valve body (16) is matched with the two valve switches (12), the rotating core notch (12a) and the switch pull groove (12c) for switching; the logarithmic pilot screw head (18) movably installed in the logarithmic pilot screw body (17) of the valve body (16) is provided with the logarithmic pilot screw head concave right side (18a), the logarithmic pilot screw head concave left side (18b), the logarithmic pilot screw head convex right side (18d), the logarithmic pilot screw head convex left side (18c) on the cross section, and the logarithmic pilot screw head The right side (18a) of the screw head concave and the left side (18b) of the logarithmic pilot screw head concave cooperate with each other to form a concave shape. After spiral scanning, they become a logarithmic pilot screw core concave groove (20) that is approximately similar to a logarithmic spiral and has the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, so as to guide and make clearance activity micro-motion and micro-rotation with the logarithmic pilot screw body (17) of the valve body (16). After spiral scanning, the logarithmic pilot screw head (18) also forms another logarithmic pilot screw groove (19) that is approximately similar to a logarithmic spiral and has the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, so as to facilitate the impeller effect to provide power for micro-rotation under fluid pressure. The logarithmic pilot screw groove (19) and the logarithmic pilot screw core concave groove (20) are preferably provided with a plurality of grooves, and the plurality of grooves are ... The groove (20) has its own unique functions; the logarithmic pilot screw core (1) is flexible and elastic, and the screw groove and the concave groove have extrusion creeping during movement, which is beneficial to pressure regulation; the advantage is that it overcomes the inability of conventional two-way valves to regulate pressure and solves the long-standing problem of the valve core stuck and occasional failure and the blocking of the damping hole caused by scale and debris in the conventional double-pressure regulating valve, because the valve core can move and rotate; the advantages of the improved two-way valve for automatically regulating water pressure are: first, a timer is added to automatically regulate water pressure more accurately; second, the one-way ball is improved, and a one-way logarithmic spiral cone core with a similar logarithmic spiral having the characteristic that the pressure angle of the logarithmic spiral is equal everywhere is added, and the top of the one-way ball head is provided, and the one-way ball head is provided, and the one-way logarithmic spiral cone core is provided with a one-way ball head, and the one-way ball head is provided with a one-way logarithmic spiral cone core, and the one-way logarithmic spiral cone core ... The rear part is provided with a guide handle with a spring outside, and the two concave edges of the spiral scanning cross section of the one-way logarithmic spiral cone core near the damping passage are the first concave arc edge (8a) and the second concave arc edge (8b), which are beneficial to the one-way damping valve. The ball plus rotating core can slightly rotate and pulsate along the approximate logarithmic spiral groove, so that a small amount of overflow can flow to the damping circuit near the top of the ball head of the spiral cone core near the damping passage, so that it is not easy to get stuck. Drip irrigation hopes to have leakage, and does not need to be too tight in the one-way direction. Pressure regulation requires damping, but if only damping is used without the one-way direction, the flow is too strong due to excessive damping. In order to pursue a balanced pressure regulation effect, there are slight rotations and pulsations to prevent static scaling and blockage, thereby solving the long-standing problem of occasional failure.And third, the filtering and epidemic prevention measures are further improved, and a copper ion filter cover (d15g) is provided to be combined with a filter membrane (10) and a filter noise reduction core (11) to form a triple filtering and epidemic prevention measure. Because the copper ion filter cover contains copper, copper ions produced in water and aerosol have a certain antibacterial and epidemic prevention effect; it is also found that the soft core of the main control valve is soft and preferably has a Shore hardness of 70 degrees; and fourth, the logarithmic pilot screw head (18) is improved. The logarithmic pilot screw head convex right side (18d) and the logarithmic pilot screw head convex left side ( The straight sides of 18c) are curved sides, and their side profiles are similar to logarithmic spirals to obtain the characteristic that the pressure angle of the logarithmic spiral is equal everywhere, so that the improved logarithmic pilot screw groove (19) has a further impeller effect under fluid pressure and better provides power for micro-rotation; the first scheme of the two-way valve for automatic water pressure regulation and the second scheme of the improved two-way valve for automatic water pressure regulation have their own advantages and complement each other, and have their own uses in different occasions; the former is mostly used for drip irrigation, and the latter is mostly used for timing and precision. ;

[0119] An electronic timer capable of remote sub-ultrasonic control is characterized in that a remote control electrical box (41) and an electromagnetic pilot valve having an electromagnetic coil (21m) are arranged on a remote timing body (22c), a hollow solenoid (21m2) is arranged inside the electromagnetic coil (21m), the middle part of the hollow solenoid passes through an electromagnetic iron core (21n) to operate the electromagnetic pilot valve, and a circuit board of the remote control electrical box (41) is provided with a receiving circuit and a time base circuit to receive the sub-ultrasonic remote control of a passive airbag transmitter; sometimes it is felt that it is not convenient to turn on and off by toggling a switch, and a general remote control device requires people to hold the remote control device in their hands. There is a remote control, so it is not very convenient. Here we use a toy-style modified airbag, using 18kHz sound waves as remote control signals. The hearing range of the human ear is Hz-20kHz. Above 20kHz is ultrasonic wave that is inaudible to the human ear. Although the 18kHz sound wave is within the audible sound wave range, it is at the high end edge of the audible sound wave and is close to the lowest frequency of ultrasonic wave. The human ear is already very insensitive to it and can only hear slight sub-sounds. Therefore, this sound wave is called sub-ultrasonic wave. Using this sound wave as a remote control command will not affect and interfere with the lives of others. This transmitter is passive. When using it, you only need to pinch the transmitting airbag with your hand to remotely control it; The modified airbag is slightly modified on the basis of the existing airbags and air whistle of the toy airbags on the market. A parabolic small opening (41p2) shaped like a drop of water is opened behind the original air whistle mouth (41p) to facilitate the harmonic effect; the transmitter is a rubber ball compressed air tongue-shaped sound whistle with a parabolic small opening (41p2). When the rubber airbag is pinched by hand, a pulse airflow of a certain pressure is input into the whistle body through the air opening. When the airflow passes through the narrow slit, it is quickly ejected and impacts the air whistle mouth. At the same time, with the cooperation of the parabolic small opening, cavity resonance is generated, and sound waves are radiated outward from the wedge of the logarithmic spiral of the air whistle mouth to control the remote control The receiving circuit provided on the circuit board of the control electrical box (41) is used to receive the sub-ultrasonic remote control of the passive airbag transmitter, thereby forming an electronic timer that can be remotely sub-ultrasonic controlled so as to cooperate with various valves and connectors of appliances; the electronic timer that can be remotely sub-ultrasonic controlled is characterized in that a control circuit having a receiving sound wave transducer B, a frequency-selective amplifier VT1 and a voice-controlled integrated circuit A is provided on the remote control electrical box (41) provided on the remote timing body (22c), so as to link the hollow solenoid (21m2) provided in the electromagnetic coil (21m) through the time delay contact K1 of the time relay K to attract the electromagnetic pilot valve.

[0120] The electronic timer can be remotely controlled by sub-ultrasonic wave, uses sub-ultrasonic wave with little interference, and is easy to manufacture and match; it has a receiving sound wave transducer B, a frequency-selective amplifier VT1, a voice-controlled integrated circuit A, and a time relay K to operate a modified valve soft core (21a); ​​the receiving sound wave transducer B is a parallel electret capacitor element containing an aluminum-plated polyester film MP and a piezoelectric ceramic piece, and is used in conjunction with the modified air bag when a small opening (41p2) is opened behind the original air flute mouth (41p) using the same tool, the same machine model, and the same contour trajectory, so as to achieve consistency to improve sensitivity and be beneficial to harmonic effect and no interference.

[0121] Further improvement, the valve core timer which can be remotely controlled is provided with a control circuit having a sound wave transducer B and a sound control integrated circuit A, and the hollow solenoid (21m2) provided in the electromagnetic coil (21m) is controlled by the programming timer A2 to attract the electromagnetic iron core (21n) to operate the modified valve soft core (21a) to control the valve water flow in a timely manner, and the characteristic is that the model (CD4541) of the programming timer A2 provided therein is a CMOS programmable timing integrated circuit, and when the external potentiometer RP2 and the capacitor C7 are connected After the value of is determined, the oscillation frequency of the internal oscillator is determined; in order to meet the high-end demand of not only setting the time for watering but also flexibly indicating whether to accurately adjust the liquid supply according to the intensity of sunlight, a capacitor C5 of 220μ, a resistor R11 of 3k and an LED light-emitting diode are added to the programming timer A2, which is mainly used to indicate the working state of the circuit for easy debugging; it is also characterized in that the modified valve soft core (21a) is provided with a valve soft core socket (21t2) and a valve soft core flap (21t3); the The valve core socket (21t2) is arranged in the concave trough near the edge of the disc where the spring is placed, the cross section of which is a disc surrounded by a cosine function curve. The valve core socket (21t2) is a through hole but not a round hole. The valve core socket (21t2) is a multi-petal multi-wave pilot valve hole. Even when the round cross section of the placed spring is inserted, there is a tiny gap so that the hole is not sealed and still has a pilot effect. The valve core petal (21t3) provided on the modified valve core (21a) is arranged in the modified valve core. The cross section of the core (21a) is on the high peak at the center of the disk surrounded by the cosine function curve. The center of the valve soft core petal (21t3) is provided with a soft core petal with four bosses and four fan-shaped petal grooves to facilitate the coordination of the valve stem and the soft core petal of the electromagnetic core (21n) so that the modified valve soft core can have stronger rigidity and flexibility. The pilot valve port (21) on the modified valve soft core (21a) can be changed with different specifications and models either inside the valve soft core socket (21t2) for precise regulation or outside when rough and large flow regulation is required.

[0122] Benefits of remotely controlled spool timers:

[0123] After continuous improvements, first changing the circuit, then the valve core, and then the insert spring, we discovered that the skewed spring blocking the pilot port was one of the causes of occasional failure. Solving the problem of occasional failure is an international and long-standing problem.

[0124] Further improvement, the remotely controlled spring timer is provided with a control circuit having a sound wave transducer B and a sound control integrated circuit A, and the hollow solenoid (21m2) provided in the electromagnetic coil (21m) is controlled by the programming timer A2 to attract the electromagnetic iron core (21n) to operate the modified valve soft core (21a) to control the valve water flow in a timely manner. The model (CD4541) of the programming timer A2 provided therein is a CMOS programmable timing integrated circuit. When the values ​​of the external potentiometer RP2 and the capacitor C7 are determined, the oscillation frequency of the internal oscillator is determined; and in order to cooperate with watering, not only the timing is required The modified valve core (21a) is provided with a valve core socket (21t2) and a valve core flap (21t3); the valve core socket (21t2) is arranged in a concave trough close to the edge of the disk where the spring is placed, and the cross section of the modified valve core (21a) is a disk surrounded by a cosine function curve. The valve core socket (21t2) is a through hole. But it is not a round hole. The valve core socket (21t2) is a multi-petal multi-wave pilot valve hole. Even when the circular cross-section of the installed spring is inserted, there is a tiny gap so that the hole is not sealed and still has a pilot effect; the valve core petal (21t3) provided on the modified valve core (21a) is arranged on the high peak at the center of the disk whose cross-section is a disk surrounded by a cosine function curve. The center of the valve core petal (21t3) is provided with a soft core petal with four bosses and four fan-shaped petal grooves to facilitate the matching of the valve stem and the soft core petal of the electromagnetic core (21n), so that the modified valve core is more enhanced. The said remotely controllable spring timer is provided with a control circuit having a sound wave transducer B and a sound control integrated circuit A, and the programming timer A2 is used to control the hollow solenoid (21m2) provided in the electromagnetic coil (21m) to attract the electromagnetic iron core (21n) to manipulate the pilot valve port composed of the modified valve soft core (21a) and the pin spring (21b) to control the valve water flow in a timely manner, characterized in that the pin spring (21b) is a compression coil spring with four turns, and the upper and lower ends are tightly connected, the lower end is tightened and then ground, the upper end is as flat as possible, and the upper end is bent and extended downward by 1.5 times the length of the spiral tube of the natural spiral spring to form the plug pin (21s); the plug pin (21s) is subjected to carbon-nitrogen-boron three-element co-diffusion heat treatment, and is placed in a mixture of borax, carbon powder and urea at 723 degrees. The plug pin is preferably silvery white in appearance, so as to be strong on the outside and soft on the inside and resistant to corrosion; the plug pin (21s) is inserted into the valve core socket (21t2) on the modified valve core (21a), and there will be a slight gap between the two in any case to play a leading role; the lower end of the plug pin spring (21b) is tightened and then ground flat, so that it is easy to fit in the concave trough of the placement spring near the edge of the disk of the modified valve core (21a), which is a disk surrounded by a cosine function curve, which is beneficial to the tacit cooperation between the plug pin spring (21b) and the modified valve core (21a), thereby improving the quality and grade of the remotely controlled plug spring timer. .

[0125] The remotely controlled spring timer is continuously improved by first changing the circuit, then the valve core, and then the spring. It is found that the spring deflection blocking the pilot port is one of the reasons for occasional failure. A remote control is provided to manipulate the pilot valve port composed of the modified valve soft core (21a) and the pin spring (21b) to control the valve water flow at a fixed time. The lower end of the pin spring (21b) is tightened and then ground flat, and carbon, nitrogen and boron three-element co-diffusion heat treatment is performed, and it is placed in a mixture of borax, carbon powder and urea at 723 degrees; the lower end of the pin spring (21b) is tightened and then ground flat, so it is easy to fit in the low concave trough of the cosine function curve, which is beneficial to the tacit cooperation between the pin spring (21b) and the modified valve soft core (21a), thereby improving the high-end quality and grade of the product.
