Description

Technical Field

[0001] The present invention relates to the technical field of valve bodies, and more particularly to an intelligent water-saving valve. Background Art

[0002] A water-saving valve is a device for efficiently managing water resources. It helps achieve water-saving goals by precisely controlling water flow, regulating flow and pressure. With the help of an intelligent control system and motor, the water-saving valve can achieve intelligent on-off control according to different irrigation needs, thereby optimizing energy-saving irrigation activities. However, when the valve disc inside the valve is closed, wear easily occurs between the valve disc and the inner wall of the valve, resulting in a gap, which in turn causes leakage and affects the effectiveness of agricultural water-saving irrigation. To solve this problem, the existing Chinese patent with announcement number CN221569448U proposes an intelligent agricultural water-saving valve, whose design includes a valve body and a blocking and sealing device. The device realizes reciprocating transmission of the moving rod through the cooperation of a connecting rod, a gear and a moving rod. When the valve disc is in the closed state, the sealing ring can effectively block the gap between the valve disc and the valve body, significantly improving the closed sealing. This innovative design not only solves the gap leakage problem, but also improves the overall sealing performance of the valve, providing a more reliable solution for agricultural water-saving irrigation.

[0003] However, this sealing device and the water-saving valve use independent electric drive control, which not only makes it difficult to achieve synchronous operation, but may also cause water stopping delays, affecting the timeliness and reliability of equipment operation; in addition, to improve the cleanliness of the outlet water, a filtration system is usually installed in the valve body. However, for water-saving valves equipped with a filtration system, the replacement process of the filtration system is relatively complicated, which not only increases the difficulty of maintenance, but may also affect the long-term stable operation of the equipment.

DETAILED DESCRIPTION

[0036] The technical solutions of the present invention will be described clearly and completely below in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The intelligent water-saving valve involved in the present invention is not limited to the various structures described in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Reference Figure 1-14The present invention provides an intelligent water-saving valve, including a valve body 1, whose left and right ends are respectively sealed and connected to the water inlet pipe 2 and the drain pipe 3 through flanges; a longitudinally assembled valve stem assembly 4 is provided in the middle of the valve body 1, and the valve stem assembly 4 consists of a valve disc 401, a valve cover sealing seat 402 and a connecting shaft 403, wherein the valve disc 401 can rotate horizontally in the valve body 1, and its top end passes through the valve cover sealing seat 402 and is coaxially connected to the connecting shaft 403, and the valve cover sealing seat 402 is sealed and fixed to the top of the valve body 1; an adjusting slider assembly 5 is horizontally provided in the valve cover sealing seat 402, and transmission assemblies 6 are symmetrically arranged at both ends of the adjusting slider assembly 5, the left transmission assembly 6 cooperates with the auxiliary flow limiting assembly 7 in the water inlet pipe 2 for transmission, and the right transmission assembly 6 is transmission-connected to the filter assembly 8 in the drain pipe 3.

[0038] In this embodiment, it should be specifically explained that water flows in from the water inlet pipe 2, and the water flow rate is controlled by adjusting the opening between the valve disc 401 and the inner wall of the valve body 1, and finally the water flows through the drain pipe 3 to the water consumption end;

[0039] The inlet and outlet of the valve body 1 are both tapered. The inlet tapered opening is used to diffuse the water introduced by the inlet pipe 2 into the internal cavity of the valve body 1, while the outlet tapered opening converges the water and directs it to the drain pipe 3. The inlet tapered opening is expanded to reduce water flow impact and avoid turbulence, while the outlet tapered opening is narrowed to improve water flow guidance and enhance delivery efficiency. The bidirectional tapered structure cooperates to form a stable flow state and reduce pressure loss.

[0040] A motor is mounted on top of the valve cover sealing seat 402. This motor can be a reversible motor. Its output shaft passes through the valve cover sealing seat 402 and forms a coaxial transmission structure with the connecting shaft 403. The motor control terminal is connected to the control system using a PLC controller. The start and stop logic control of the motor is achieved through a preset program. The control system outputs a PWM signal to adjust the motor speed. The programmable controller realizes the forward and reverse switching function.

[0041] In this article, all the positional relationships we discuss about front, back, left, and right are based on Figure 1-2 These directions are defined by the perspective presented. They have no actual geographical or physical meaning. They are merely a reference framework to help readers understand the content of the article more intuitively. In this way, we can more clearly show the relative position relationship between the various parts, making the entire discussion process easier to understand and follow. Please note that this custom direction identification is only for internal use in this article and does not represent any absolute direction or position in the real world.

[0042] Reference Figure 2-7The left and right side walls of the valve cover sealing seat 402 are provided with openings for inserting the adjusting slider assembly 5. The adjusting slider assembly 5 consists of a guide rail 501, a two-way guide rod 502 and a hinge head 503. The guide rail 501 can be inserted into the opening and can be stably fixed by adjusting the lock size of the adjustable constraint assembly 11. The two-way guide rod 502 is slidably arranged inside the guide rail 501, and hinge heads 503 are symmetrically distributed at its left and right ends. When the hinge head 503 is relatively slidably connected to the swing angle actuator arm 601, the swing angle of the swing angle actuator arm 601 can be adjusted by moving the hinge head 503, thereby driving the transmission assembly 6 to change its shape.

[0043] A gear 404 coplanar with the through-port is fixedly sleeved on the surface of the connecting shaft 403, and the gear 404 meshes with the rack 5021 of the two-way guide rod 502; the lateral width of the through-port is designed to be larger than the thickness of the guide rail 501, and the left and right side walls of the valve cover sealing seat 402 are also equipped with an adjustable constraint assembly 11 located at the periphery of the through-port. By adjusting the locking range of the adjustable constraint assembly 11, the slider assembly 5 can be quickly disassembled and assembled, which is convenient for repair and replacement of the two-way guide rod 502 when it is worn due to long-term use.

[0044] In this embodiment, it should be specifically explained that the adjustable constraint assembly 11 is composed of a fixed base 1101, a sliding adjustment block 1102, a guide screw 1103 and a locking nut 1104, wherein the fixed base 1101 is welded to the outer periphery of the through-hole, and its interior is slidably connected to the sliding adjustment block 1102 that can be adjusted forward and backward; the guide screw 1103 passes through the fixed base 1101 and the sliding adjustment block 1102, and forms a threaded fit with the locking nut 1104 on the rear side wall of the sliding adjustment block 1102; the fixed base 11 The rear side wall of 01 is open, and the sliding adjustment block 1102 and the fixed base 1101 together form a locking mouth for the guide rail 501. By tightening or loosening the locking nut 1104, the size of the locking mouth can be adjusted to achieve the tightening or loosening of the guide rail 501. This structure can accurately adjust the rack 5021 of the two-way guide rod 502 to a position that is adapted to mesh with the connecting shaft 403 to meet transmission requirements. In addition, when maintenance is required, the two-way guide rod 502 can be effectively separated from the connecting shaft 403, and the adjustment slider assembly 5 can be removed without any obstacles.

[0045] The middle part of the two-way guide rod 502 is a rack 5021, and its two ends and the socket 5022 are integrally formed. The outer end of the socket 5022 is connected to the limit pin 5023 by plugging and unplugging. When it is necessary to disassemble the adjustment slider assembly 5, the limit pin 5023 and the hinged joint 503 assembled on its surface are first removed, and then the restraining force of the adjustable restraint assembly 11 is released. The guide rail 501 and the internal two-way guide rod 502 can be pulled out as a whole. This disassembly process realizes modular maintenance of the adjustment slider assembly 5, facilitating the inspection or replacement of internal components.

[0046] The hinged joint 503 is connected to the surface of the limit bolt 5023; the hinged joint 503 and the limit bolt 5023 can be connected in two ways: fixed sleeve connection or rotating sleeve connection. Regardless of the connection method, when the two-way guide rod 502 moves laterally, the hinged joint 503 can effectively guide the movement trajectory of the swing angle actuator arm 601, thereby accurately triggering the type-changing action of the transmission assembly 6; this design ensures that the mechanism can maintain reliable functional realization under different assembly methods.

[0047] Reference Figure 8 、 Figure 9 、 Figure 10 and Figure 14 The transmission assembly 6 includes a swing angle actuator arm 601, a connecting rod compensator 602, and a bearing seat 603. The swing angle actuator arm 601 is rotatably connected to a rotating shaft passing through the center of the bearing seat 603. Its bottom end is sealed through a first water-stopping tough barrier 604, and its top end extends outward to pass through the hinge joint 503. One end of the connecting rod compensator 602 is rotatably connected to the ball head at the bottom end of the swing angle actuator arm 601 via a rotating shaft. The other end of the connecting rod compensator 602 is adhered to the sliding base 702 in the auxiliary current limiting assembly 7 via a tough block.

[0048] The auxiliary flow limiting assembly 7 includes a conical plug 701, a sliding base 702 and a connecting transition block 703, wherein the sliding base 702, the connecting transition block 703 and the conical plug 701 are connected in sequence from left to right, the sliding base 702 is slidably engaged in the slide groove of the water inlet pipe 2, and the conical plug 701 is adapted to the conical mouth of the valve body 1.

[0049] In this embodiment, it should be specifically noted that an arc-shaped opening is provided on the top of the bearing seat 603 for the deflection movement of the swing angle actuator arm 601, and a first water-stopping and tough barrier layer 604 is provided on the bottom wall of the bearing seat 603. The contact portion between the first water-stopping and tough barrier layer 604 and the swing angle actuator arm 601 is sealed and adhered. This design can ensure that the swing angle actuator arm 601 deflects within a limited range and effectively prevents water leakage.

[0050] The inner diameter of the hinge head 503 must be larger than the cross-sectional diameter of the swing angle actuator arm 601 to ensure that it can adapt to the angle change of the swing angle actuator arm 601 or the adjustment of the contact point between the hinge head 503 and the swing angle actuator arm 601 when pulling the swing angle actuator arm 601.

[0051] A toughness block is provided between the connecting rod compensator 602 and the sliding base 702, so that the connecting rod compensator 602 can transmit the thrust generated at the bottom end when the swing angle actuator arm 601 swings in a circle; during this process, the connecting rod compensator 602 realizes adaptive adjustment and transmits the rightward thrust to the sliding base 702.

[0052] Reference Figure 10-13The filter assembly 8 includes a cylinder 801 and a filter element 802 assembled in the filling groove of the cylinder 801. The right end of the cylinder 801 is a connecting frame, and the connecting rod compensation member 602 on the right side is connected to the connecting frame of the cylinder 801 through a toughness block;

[0053] The filter assembly 8 moves to the leftmost area, which is the replacement area of ​​the drain pipe 3. A quick locking assembly 9 is provided at the bottom thereof. The quick locking assembly 9 consists of a connecting cover 901, a latch-type locking rod 905, a rotating chuck 906, a pivot pin 907 and a safety limit pin 908. The top opening of the connecting cover 901 is connected to the arc-shaped opening of the bottom wall of the drain pipe 3 by welding; the rotating chuck 906 is rotatably mounted at the bottom opening of the connecting cover 901 by the pivot pin 907. The latch-type locking rod 905 can pass through the slot of the rotating chuck 906 and make its top end tightly fit with the flange outer wall of the filter plate 8021. At the same time, the safety limit pin 908 is inserted into the pin holes of the latch-type locking rod 905 and the rotating chuck 906 to limit the latch-type locking rod 905.

[0054] The filter assembly 8 moves to the rightmost area, which is the shaking area of ​​the drain pipe 3. A vibration transmission mechanism 10 that can be inserted is set at the bottom. The vibration transmission mechanism 10 includes a vibration transmission rod 1001, a second water-stopping tough barrier 1002, a vibration coupling head 1003 and a vibrator housing 1004, wherein the vibration transmission rod 1001 is sealed through the second water-stopping tough barrier 1002, and the second water-stopping tough barrier 1002 is sealed and adhered to the bottom wall of the shaking area. The bottom end of the vibration transmission rod 1001 is fixedly connected to the vibration coupling head 1003, and the vibration coupling head 1003 can be connected to the output end of the vibrator. The vibrator is assembled in the vibrator housing 1004, and the vibrator housing 1004 is welded to the outer wall of the drain pipe 3 below the shaking area.

[0055] In this embodiment, it should be specifically explained that the filter element 802 is composed of a filter plate 8021, a filter pad 8022, and a stabilizing ring 8023. The filter plate 8021 has a groove on the left side, and the filter pad 8022 is placed in the groove. The stabilizing ring 8023 is fixed to the front wall of the filter plate 8021 by snapping, thereby firmly fitting the filter pad 8022 in the groove. At the same time, the flange structure extending from the bottom of the filter plate 8021 is inserted into the arc-shaped opening at the bottom of the cylinder 801 and remains flush with the outer wall of the cylinder 801.

[0056] In addition, the quick locking assembly 9 may also include a sealing gasket 902, a pull rod 903 and a push rod 904, wherein the sealing gasket 902 passes through the side wall of the connecting cover 901 and is sealed and intercepted in its inner cavity. The sealing gasket 902 is connected to the telescopic end of the push rod 904 through the pull rod 903. When the cylinder 801 moves to the right, if its left port exceeds the position of the connecting cover 901, the sealing gasket 902, the pull rod 903 and the push rod 904 are required to ensure that when the cylinder 801 does not seal the top opening of the connecting cover 901, the sealing gasket 902 acts as a secondary sealing defense line to prevent water leakage in the drain pipe 3. The actions of the sealing gasket 902 and the latch-type locking rod 905 are implemented sequentially.

[0057] Working principle of the present invention:

[0058] Figure 1-12 The diagram shows the structural state of the water-saving valve when it is completely closed;

[0059] When the valve needs to be opened, the control system starts the motor, and the output shaft of the motor drives the valve disc 401 to rotate in the counterclockwise direction through the connecting shaft 403, so that the opening between the valve disc 401 and the valve body 1 gradually increases, thereby increasing the water flow through the valve body 1; at the same time, the connecting shaft 403 drives the gear 404 to rotate, and transmits the two-way guide rod 502 engaged with it to the left, so that the two-way guide rod 502 slides to the left along the inner wall of the guide rail 501 and gradually withdraws; the hinged joint 503 sleeved on the surface of the left end limit bolt 5023 pushes the swing angle actuator arm 601 when moving to the left, and appears to slide down along the surface of the swing angle actuator arm 601, causing the swing angle actuator arm 601 to deflect to the left with the rotating shaft passing through the bearing seat 603 as the center of the circle; One end of the rod compensator 602 is rotatably connected to the ball head at the bottom end of the swing angle actuator arm 601 through a rotating shaft, and the other end is connected to the center of the sliding base 702 through a toughness block. Therefore, the connecting rod compensator 602 can transmit the thrust generated at the bottom end when the swing angle actuator arm 601 swings in a circle, and itself tilts downward at the left end, thereby making adaptive adjustments and transmitting the rightward thrust to the sliding base 702, pushing the entire auxiliary flow limiting assembly 7 to move right until the conical plug 701 is separated from the conical opening at the water inlet end of the valve body 1; this process realizes the synchronous operation of the valve disc 401 and the conical plug 701 to switch the valve, forming a double sealing mechanism, significantly reducing the water pressure load on the valve disc 401, thereby effectively extending the service life of the core components;

[0060] At the same time, when the two-way guide rod 502 slides to the left, the hinge joint 503 sleeved on the surface of the limit bolt 5023 at its right end moves to the left accordingly, and slides down along the surface of the swing angle actuator arm 601, driving the swing angle actuator arm 601 to deflect to the left with the rotation axis passing through the bearing seat 603 as the center of the circle; one end of the connecting rod compensator 602 is rotatably connected to the ball head at the bottom end of the swing angle actuator arm 601 through the rotation axis, and the other end is connected to the center of the cylinder 801 through the toughness block, so that the connecting rod compensator 602 can transmit the rotation of the bottom end of the swing angle actuator arm 601 when the swing angle actuator arm 601 swings in a circle. The generated traction lifts its right end, thus completing the adaptive adjustment. The rightward traction is then transmitted to the filter element 802, pulling the entire filter assembly 8 to the right until the cylinder 801 contacts the vibration transmission mechanism 10. At this time, the vibration force transmitted by the vibration transmission rod 1001 will continue to act on the filter assembly 8. Since the connecting rod compensation member 602 and the cylinder 801 are connected by the toughness block, the vibration force can be transmitted to the vibration of the cylinder 801, effectively reducing the risk of the filter element 802 being blocked by sludge and ensuring that its flow capacity is maintained.

[0061] When the valve needs to be closed, the water-saving valve operates in the opposite manner to opening, so that the conical plug 701 gradually seals the conical mouth, and the filter assembly 8 is gradually pushed to the replacement area above the quick locking assembly 9; then, the staff can perform the replacement operation: pull out the safety limit pin 908, so that the latch-type locking rod 905 can be pulled out from the socket of the rotating chuck 906; rotate the rotating chuck 906 to disengage it from the bottom of the connecting cover 901. At this time, the filter element 802 can fall off from the filling groove of the cylinder 801 due to the loss of the support of the latch-type locking rod 905, and be guided outward through the connecting cover 901; in addition, if the cylinder 801 is in the valve opening stage, If the rightward movement distance exceeds the setting position of the connecting cover 901, it is necessary to configure a sealing plug gasket 902, a pull rod 903 and a point push rod 904 to ensure that when the cylinder 801 does not seal the top opening of the connecting cover 901, the sealing plug gasket 902 plays a role as a secondary sealing defense line to prevent water leakage in the drain pipe 3, which increases the corresponding parts replacement operation steps. It is necessary to further start the point push rod 904 so that its telescopic end can pull out the sealing plug gasket 902 through the pull rod 903 to fully open the passage of the connecting cover 901; after the old parts are discharged, replace them with new parts, and reset the quick locking assembly 9 to stably install the filter element 802 in the cylinder 801;

[0062] The specific steps for replacing the filter element 802 are as follows: first, disassemble and separate the stabilizing ring buckle 8023 from the front side of the filter plate 8021, then take out the filter pad 8022 and replace it; then, reseal the stabilizing ring buckle 8023 to ensure that the filter pad 8022 is firmly attached to the front wall of the filter plate 8021.

[0063] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, these should be included under the protection of the present invention.
