Description

Technical Field

[0001] This utility model relates to the field of water meter counter technology, specifically a gear water meter counter with anti-backflow function. Background Technology

[0002] The main function of a gear water meter counter is to record and display water consumption. The counter measures water flow through the rotation of gears and displays the cumulative water usage. Specifically, the gear mechanism inside the water meter rotates as water flows through, turning a certain angle with each flow. These rotating gears are connected to the counter via a mechanical transmission device, thus recording the water usage. The internal structure of a gear water meter mainly includes a metering mechanism and a counting mechanism. The metering mechanism, the "heart" of the water meter, consists of a gearbox, impeller box, integral impeller, center, and adjusting plate, and is responsible for measuring water flow. The counting mechanism records water usage through the rotation of gears; common forms include pointer type, digit wheel type, and pointer-digit wheel combination type. The existing device has the following problems when in use: the anti-backflow structure in the water meter is used in conjunction with the spring. However, under the long-term impact of water flow, the spring is deviated in force, causing the spring to tilt. The flow-blocking part at one end of the spring cannot accurately block the water inlet, resulting in the failure of the anti-backflow effect. Moreover, the subsequent maintenance of the anti-backflow structure is very inconvenient and requires a lot of manpower and time. Utility Model Content

[0003] The purpose of this invention is to provide a gear water meter counter with anti-backflow function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gear water meter counter with anti-backflow function, comprising an inlet pipe, a connecting pipe, and a mounting plate. A connecting pipe is installed at one end of the inlet pipe, and a mounting plate is disposed inside the connecting pipe. A connecting post is disposed inside the mounting plate, and a connecting plate is connected to one end of the connecting post. A return spring is fixedly connected to one side of the connecting plate, and a flow-blocking ball is fixedly connected to one end of the return spring. The end of the inlet pipe away from the connecting pipe is connected to the water meter body, and an outlet pipe is connected to one side of the water meter body.

[0005] By adopting the above technical solution, water is supplied to the inside of the connecting pipe through the inlet. The water pressure pushes the flow-blocking ball to squeeze the reset spring and move it. The flow-blocking ball leaves the inlet, making the inlet fully open. Thus, the water flows through the water meter body into the outlet pipe. The water meter body shuts off the water supply, and the water pressure gradually weakens. Under the action of the reset spring, the flow-blocking ball moves. After the flow-blocking ball enters the inlet, the backflow prevention effect is achieved.

[0006] Preferably, the connecting pipe has grooves on both sides inside, the flow-blocking ball has connecting rods on both sides, one end of the connecting rod is rotatably connected to a pulley, and the pulley is slidably connected to a groove.

[0007] By adopting the above technical solution, the connecting rods on both sides of the flow-blocking ball drive the pulleys to move in the chute, so that the flow-blocking ball moves in a straight line, thus allowing the flow-blocking ball to accurately enter the interior of the water inlet, avoiding the flow-blocking ball from deviating and causing the anti-backflow effect to fail.

[0008] Preferably, the connecting pipe has internal threads, and the threads are used to connect to a mounting plate.

[0009] By adopting the above technical solution, the connecting pipe and the water inlet pipe can be disassembled, and the mounting plate can be rotated open, which facilitates internal maintenance.

[0010] Preferably, a water inlet is provided at one end of the connecting pipe, and a sealing ring is provided at the port of the water inlet.

[0011] By adopting the above technical solution, the sealing ring, in conjunction with the flow-blocking ball, improves the sealing performance.

[0012] Preferably, a rotating motor is installed at the top of the water outlet pipe, and a valve plate is fastened to the output end of the rotating motor.

[0013] By adopting the above technical solution, the valve plate is rotated by starting the rotating motor on the water outlet pipe, thereby closing the inside of the water outlet pipe and increasing the effect of preventing backflow.

[0014] Preferably, the mounting plate is annular, and the connecting pipe is bolted to a water inlet pipe.

[0015] By adopting the above technical solution, the connecting pipe and the water inlet pipe can be disassembled and installed using bolts, which facilitates subsequent maintenance of the internal parts of the connecting pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: Under the action of the return spring, the flow-blocking ball moves, and the connecting rods on both sides of the flow-blocking ball drive the pulley to move in the groove, so that the flow-blocking ball moves in a straight line, thereby the flow-blocking ball can accurately enter the interior of the water inlet, avoiding the flow-blocking ball from deviating and causing the anti-backflow effect to fail, thus improving the anti-backflow effect. By starting the rotating motor on the water outlet pipe to drive the valve plate to rotate, the interior of the water outlet pipe is closed, increasing the anti-backflow effect. After the connecting pipe and the water inlet pipe are disassembled, the mounting plate can be rotated open, thus facilitating internal maintenance. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a technical solution: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A gear-type water meter counter with anti-backflow function includes an inlet pipe 2, a connecting pipe 4, and a mounting plate 11. The connecting pipe 4 is installed at one end of the inlet pipe 2. The mounting plate 11 is located inside the connecting pipe 4, and a connecting post 13 is located inside the mounting plate 11. A connecting plate 12 is connected to one end of the connecting post 13. A return spring 8 is fixedly connected to one side of the connecting plate 12, and a flow-blocking ball 6 is fixedly connected to one end of the return spring 8. A water inlet 5 is located at one end of the connecting pipe 4, and a sealing ring is provided at the port of the water inlet 5. The end of the inlet pipe 2 away from the connecting pipe 4 is connected to the water meter body 1. Water is supplied to the interior of the connecting pipe 4 through the water inlet 5. The flow pressure pushes the flow-blocking ball 6 to squeeze the return spring 8 and move it away from the inlet 5, making the inlet 5 fully open. Thus, the water flows through the water meter body 1 into the outlet pipe 3. The water meter body 1 closes the water flow, and the water pressure gradually weakens. Under the action of the return spring 8, the flow-blocking ball 6 moves and enters the interior of the inlet 5, achieving the effect of preventing backflow. A rotating motor 14 is installed on the top of the outlet pipe 3. The output end of the rotating motor 14 is fastened to a valve plate 15. The outlet pipe 3 is connected to one side of the water meter body 1. By starting the rotating motor 14 on the outlet pipe 3, the valve plate 15 is rotated, closing the interior of the outlet pipe 3 and improving the effect of preventing backflow.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The connecting pipe 4 has grooves 7 on both sides inside, and the flow-blocking ball 6 has connecting rods 9 on both sides. One end of the connecting rod 9 is rotatably connected to a pulley 10, and the pulley 10 is slidably connected to the groove 7. The connecting rods 9 on both sides of the flow-blocking ball 6 drive the pulley 10 to move in the groove 7, so that the flow-blocking ball 6 moves in a straight line, improving the accuracy of the flow-blocking ball 6 entering the water inlet 5 and preventing the flow-blocking ball 6 from deviating, which would cause the anti-backflow effect to fail. The connecting pipe 4 has threads inside, and the threads are connected to the mounting plate 11. The mounting plate 11 is set as a ring. The water inlet pipe 2 is installed on the connecting pipe 4 by bolts. After the connecting pipe 4 and the water inlet pipe 2 are disassembled, the mounting plate 11 can be rotated open to facilitate internal maintenance.

[0025] Working principle: Water is supplied to the inside of the connecting pipe 4 through the inlet 5. The water pressure pushes the flow-blocking ball 6 to squeeze the return spring 8 and move it away from the inlet 5, so that the inlet 5 is fully opened. Thus, the water flows through the water meter body 1 and into the outlet pipe 3. The water meter body 1 closes the water supply, and the water pressure gradually weakens. Under the action of the return spring 8, the flow-blocking ball 6 moves. The connecting rods 9 on both sides of the flow-blocking ball 6 drive the pulley 10 to move in the slide groove 7, so that the flow-blocking ball 6 moves in a straight line. Thus, the flow-blocking ball 6 can accurately enter the inside of the inlet 5, avoiding the flow-blocking ball 6 from deviating and causing the anti-backflow effect to fail, thus achieving the anti-backflow effect. By starting the rotating motor 14 on the outlet pipe 3, the valve plate 15 is rotated, and the inside of the outlet pipe 3 is closed, increasing the anti-backflow effect.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
