Description

Technical Field

[0001] This utility model relates to the field of measuring instruments, and in particular to a smart valve-controlled water meter without magnetic sensing. Background Technology

[0002] Water meters, as a type of measuring instrument, mostly measure the cumulative flow of water. They are generally divided into two categories: volumetric water meters and velocity water meters. They are flow meters that use the direct mechanical movement of the moving wall volume measuring chamber or the effect of the water flow velocity on the impeller to calculate the volume of water flowing through the tap water pipe. Existing water meters are all installed by the waterworks at the water inlet end of each user's house.

[0003] Chinese patent CN208872365U discloses a smart water meter with a valve. The device uses a signal transmitting pointer and a signal acquisition device to work together. When a malfunction occurs or the signal transmitting pointer reverses, the data collected by the signal acquisition device is zero or reversed. If the switch valve is in the open state, the control board will control the driver to close the switch valve and stop the water supply.

[0004] Taking the above-mentioned utility model as an example, the original equipment does not have the performance of water flow regulation, which leads to the need to repeatedly adjust the valve core in the traditional equipment. The flow rate of water is adjusted by repeatedly rotating the valve core. However, in this process, the valve core is excessively worn under the impact of water pressure, so it is necessary to improve it on the basis of the original. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a non-magnetic sensing intelligent valve-controlled water meter.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a non-magnetic sensing intelligent valve-controlled water meter, comprising a meter body, a sliding cover, a display screen, a touch screen, a fixing stud, a transmission valve body, an adjusting device, and a valve core. The sliding cover is installed at the front end of the meter body, the display screen is installed at the front end of the meter body, the touch screen is located at the bottom of the display screen, the fixing stud is located at the rear end of the meter body, the transmission valve body is installed at the rear end of the meter body, the adjusting device is fixed to the left end of the transmission valve body, the valve core is rotatably connected to the inside of the transmission valve body, and the valve core is connected to the rear end of the meter body.

[0007] Preferably, the adjusting device includes a fixed cylinder, a fixing sleeve, a mounting cover, a servo motor, a limiting rod, a rocker arm, a flow-blocking assembly, a mounting slide, and a transmission groove. A fixing sleeve is provided at the right end of the fixed cylinder, and the fixing sleeve is threadedly fixed to the left end of the transmission valve body. The mounting cover is located at the top of the fixed cylinder. The servo motor is mounted at the front end of the fixed cylinder and is connected to the front end of the rocker arm via a coupling. The limiting rod is located inside the mounting cover. The rocker arm engages with the interior of the transmission groove for transmission. The transmission groove is located at the top of the mounting slide, which is slidably connected to the interior of the mounting cover and to the outer side of the limiting rod. The flow-blocking assembly is mounted at the bottom of the mounting slide.

[0008] In a further preferred embodiment, the flow-blocking assembly includes a fixed block, a support block, and a flow-adjusting shroud. The fixed block is disposed at the bottom of the mounting slide, and the fixed block is drivenly connected to the left end of the support block. The support block is slidably connected to the interior of the flow-adjusting shroud.

[0009] In a further preferred embodiment, the fixing cylinder and the mounting cover are arranged perpendicularly at the left end of the fixing screw sleeve.

[0010] In a further preferred embodiment, the bottom of the mounting slide is provided with a mounting groove, and the flow-blocking component can be embedded and fixed inside the mounting slide.

[0011] In a further preferred embodiment, the outer side of the fixing sleeve is provided with a thread, and the securing thread is fixed to the internal thread of the transmission valve body.

[0012] In a further preferred embodiment, the interior of the flow control fairing is a hollow structure, which allows the support block to move horizontally within the flow control fairing.

[0013] In a further preferred embodiment, the support block is configured to slide in conjunction with the interior of the flow control cover.

[0014] In a further preferred embodiment, the flow regulating shroud is made of resin, and the flow regulating shroud can bend and release water under the impact of the water flow. Subsequently, when the support block is embedded in the interior of the flow regulating shroud, the flow regulating shroud can cut off the water source and divert the flow.

[0015] The beneficial effects of this utility model are:

[0016] This invention incorporates an adjustment device. A servo motor drives a rocker arm to rotate, which engages with a transmission groove on the top of the mounting slide. This drives the mounting slide to slide horizontally along a limit rod, thereby propelling the flow-blocking component horizontally. The flow-blocking component, in conjunction with the mounting slide, allows for horizontal extension and retraction adjustment, enabling the right end of the flow-blocking component to flexibly agitate the water flow, changing its direction and frequency. This adjustment device controls the direction and frequency of the agitated water flow, preventing direct water intake into the valve core. This reduces water resistance during valve core rotation, thus decreasing wear and tear on the valve core and resolving the problem of excessive wear on the valve core under water pressure in the original equipment.

Detailed Implementation

[0024] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0025] Please see Figure 1 and Figure 2This utility model provides a non-magnetic sensing intelligent valve-controlled water meter, including a meter body 1, a sliding cover 2, a display screen 3, a touch screen 4, a fixing stud 5, a transmission valve body 6, an adjusting device 7, and a valve core 8. The sliding cover 2 is installed at the front end of the meter body 1, the display screen 3 is installed at the front end of the meter body 1, the touch screen 4 is located at the bottom of the display screen 3, the fixing stud 5 is located at the rear end of the meter body 1, the transmission valve body 6 is installed at the rear end of the meter body 1, the adjusting device 7 is fixed to the left end of the transmission valve body 6, the valve core 8 is rotatably connected to the inside of the transmission valve body 6, and the valve core 8 is connected to the rear end of the meter body 1.

[0026] Please see Figure 3 and Figure 4 This utility model provides a non-magnetic sensing intelligent valve-controlled water meter. The adjusting device 7 includes a fixed cylinder 71, a fixed screw sleeve 72, a mounting cover 73, a servo motor 74, a limit rod 75, a rocker arm 76, a flow-blocking component 77, a mounting slide 78, and a transmission groove 79. The fixed cylinder 71 is provided with a fixed screw sleeve 72 at its right end, which is threadedly fixed to the left end of the transmission valve body 6. The mounting cover 73 is provided on the top of the fixed cylinder 71. The servo motor 74 is installed at the front end of the fixed cylinder 71 and is connected to the front end of the rocker arm 76 by a coupling. The limit rod 75 is provided inside the mounting cover 73. The rocker arm 76 is engaged with the inside of the transmission groove 79 for transmission. The transmission groove 79 is provided on the top of the mounting slide 78. The mounting slide 78 is slidably connected to the inside of the mounting cover 73 and to the outside of the limit rod 75. The flow-blocking component 77 is installed at the bottom of the mounting slide 78.

[0027] In this embodiment, the fixed cylinder 71 and the mounting cover 73 are vertically arranged at the left end of the fixed screw sleeve 72. The bottom of the mounting slide 78 is provided with a mounting groove to ensure that the flow-blocking component 77 can be embedded and fixed inside the mounting slide 78. The thread provided on the outside of the fixed screw sleeve 72 ensures that the thread is fixed with the internal thread of the transmission valve body 6.

[0028] Please see Figure 5 This utility model provides a non-magnetic sensing intelligent valve-controlled water meter. The flow isolation component 77 includes a fixed block 771, a support block 772, and a flow regulating cover 773. The fixed block 771 is disposed at the bottom of the mounting slide 78. The fixed block 771 is connected to the left end of the support block 772 through a transmission connection. The support block 772 is slidably connected to the inside of the flow regulating cover 773.

[0029] In this embodiment, the interior of the flow regulating cover 773 is hollow, which facilitates the horizontal movement of the support block 772 inside the flow regulating cover 773. The support block 772 is slidably fitted inside the flow regulating cover 773. The flow regulating cover 773 is made of resin. The flow regulating cover 773 can bend and release water under the impact of the water flow. After the support block 772 is embedded inside the flow regulating cover 773, the flow regulating cover 773 can cut off the water source and divert the flow.

[0030] See Figures 1-6 When in use, the meter body 1 is installed at the connection of two sets of pipes. When water flows from the meter body 1, the touch screen 4 can detect the content in the water flow through the detection probe 9 and display the data on the display screen 3, which is convenient for staff to detect the water source. Afterwards, staff can manually click on the touch screen 4 to display the data content inside the display screen 3, which is convenient for staff to detect and record the data.

[0031] During this process, the servo motor 74 drives the rocker arm 76 to rotate. The rocker arm 76 engages with the transmission groove 79 on the top of the mounting slide 78, thereby pushing the mounting slide 78 to slide horizontally along the limit rod 75. This further pushes the fixing block 771 to move horizontally, causing the fixing block 771 to push the support block 772 to retract and support the flow control shroud 773. This causes the flow control shroud 773 to deform, changing the direction of the water flow. Furthermore, the flow-blocking component 77, in conjunction with the mounting slide 78, performs horizontal extension and retraction adjustment, allowing the right end of the flow-blocking component 77 to flexibly move the water flow.

[0032] This changes the direction of water flow, thereby altering the frequency of water flow. The regulating device 7 adjusts the direction and frequency of the water flow, preventing water from being directly drawn into the valve core 8. This reduces water resistance during valve core 8 rotation, thus reducing wear on the valve core 8 and resolving the problem of excessive wear on the valve core under water pressure in the original equipment.

[0033] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0034] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
