Description

Technical Field

[0001] This utility model relates to the field of anti-backflow PE pipe valve technology, and in particular to an anti-backflow PE pipe valve. Background Technology

[0002] Anti-backflow PE pipe valves are pipe control components made primarily of polyethylene (PE), combining anti-backflow functionality with the advantages of PE material. They are mainly divided into three types: spring-loaded anti-backflow PE valves, gravity-loaded anti-backflow PE valves, and slow-closing anti-backflow PE valves. Their main function is to precisely prevent reverse flow of fluid within the pipe, effectively avoiding equipment damage, media contamination, and decreased system operating efficiency caused by fluid backflow. Due to their excellent performance, these products are widely used in many important fields such as water supply and drainage, gas transmission, chemical production, and agricultural irrigation, providing strong protection for the safe and stable operation of pipeline systems in various industries. However, currently used anti-backflow PE pipe valves lack a filtration structure, allowing impurities in the liquid to easily become stuck at the valve disc after passing through, resulting in incomplete closure of the anti-backflow PE pipe valve. Utility Model Content

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Participation Figure 1-3As shown, an anti-backflow PE pipe valve includes a valve body 1, with an inlet pipe 2 connected to one end of the valve body 1 and an outlet pipe 3 connected to the other end. A filter structure 4 is installed inside the inlet pipe 2. The filter structure 4 includes a protective cover 401, a drain pipe 402, a sealing cover 403, a micro motor 404, a circular transmission rod 405, a connecting column 406, a rectangular scraper 407, a rectangular connecting plate 408, a filter screen 409, a rectangular transmission box 410, a first bearing 411, a first bevel gear 412, a second bevel gear 413, a second bearing 414, and a rotating rod 415. The micro motor 404 is controlled by a control switch and connected to an external power source.

[0016] Specifically, water can enter the valve body 1 from the inlet pipe 2 connected to one end of the valve body 1 and then be discharged through the outlet pipe 3 connected to the other end of the valve body 1.

[0017] Participation Figure 2-3 As shown, a protective cover 401 is installed at the upper end of the water inlet pipe 2. A micro motor 404 is installed inside the protective cover 401. A circular transmission rod 405 is connected to the rotating part of the micro motor 404. Connecting columns 406 are installed at both the front and rear ends of the inner wall of the water inlet pipe 2. Connecting columns 406 are installed at both the front and rear ends of the rectangular transmission box 410. A bearing 411 is installed at the upper end of the rectangular transmission box 410. A circular transmission rod 405 is installed on the bearing 411. A bevel gear 412 is installed at the lower end of the circular transmission rod 405. A bearing 414 is installed at the other end of the rectangular transmission box 410.

[0018] Specifically, the micro motor 404 installed inside the protective cover 401 and the circular transmission rod 405 connected to the rotating part of the micro motor 404 can be started by a control switch, so that the rotating part of the micro motor 404 drives the circular transmission rod 405 to rotate on the first bearing 411, thereby driving the first bevel gear 412 installed at the lower end of the circular transmission rod 405 to rotate.

[0019] Participation Figure 2-3 As shown, a rotating rod 415 is installed on the second bearing 414. A second bevel gear 413 is installed at one end of the rotating rod 415, and a rectangular connecting plate 408 is installed at the other end of the rotating rod 415. A first bevel gear 412 installed at the lower end of the circular transmission rod 405 meshes with the second bevel gear 413 installed at one end of the rotating rod 415. A rectangular scraper 407 is installed at the other end of the rectangular connecting plate 408. A filter screen 409 is installed on the inner wall of the water inlet pipe 2. The rectangular scraper 407 is in contact with the surface of the filter screen 409. A drain pipe 402 is connected to the lower end of the water inlet pipe 2. A sealing cap 403 is threaded onto the lower end of the drain pipe 402.

[0020] Specifically, through the rotating rod 415 installed on the second bearing 414 and the second bevel gear 413 installed at one end of the rotating rod 415, when the first bevel gear 412 rotates, because the first bevel gear 412 installed at the lower end of the circular transmission rod 405 meshes with the second bevel gear 413 installed at one end of the rotating rod 415, the rotating rod 415 is driven to rotate on the second bearing 414, thereby driving the rectangular connecting plate 408 installed at the other end of the circular transmission rod 405 to rotate, so that the rectangular connecting plate 408 drives the rectangular scraper 407 installed at the other end to rotate, cleaning the impurities on the surface of the filter screen 409. Then, the sealing cover 403 is screwed on, and the cleaned impurities are discharged from the drain pipe 402.

[0021] It should be noted that this utility model is an anti-backflow PE pipe valve, which can intercept impurities in the liquid and prevent them from getting stuck at the valve disc. Furthermore, the micro motor 404 can be activated by a control switch, causing the rotating part of the micro motor 404 to drive the circular transmission rod 405 to rotate on the first bearing 411. This, in turn, drives the first bevel gear 412 mounted at the lower end of the circular transmission rod 405 to rotate. Because the first bevel gear 412 meshes with the second bevel gear 413 mounted on one end of the rotating rod 415, the rotating rod 415 rotates on the second bearing 414. This, in turn, drives the rectangular connecting plate 408 mounted on the other end of the circular transmission rod 405 to rotate. The rectangular connecting plate 408 then drives the rectangular scraper 407 mounted on the other end to rotate, cleaning impurities from the surface of the filter screen 409 and preventing clogging. Finally, the sealing cap 403 is screwed on, and the cleaned impurities are discharged from the drain pipe 402.
