A rotating rod and impurity-scraping plates are arranged, so that the rotating rod, when rotating, drives the impurity-scraping plates on one side of the first filter screen and the second filter screen to perform a scraping operation, thereby scraping off impurities filtered on one side of the first filter screen and the second filter screen, preventing blockage of the first filter screen and the second filter screen, and eliminating the need for frequent cleaning and maintenance of the first filter screen and the second filter screen. By providing a threaded sealing post, a threaded through-hole, and a cover body, threaded installation between the threaded sealing post and the threaded through-hole is achieved, with further sealing provided between a rubber sealing material on the outer side of the threaded sealing post and the threaded through-hole; by removing the cover body and the threaded sealing post, impurities in a maintenance groove and the valve body can be cleaned out.

Description

A shut-off valve for easy handling of impurities Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a gate valve that facilitates the handling of impurities. Background Technology

[0002] A gate valve is a valve in which the closing element (valve disc) moves along the centerline of the valve seat. Its working principle relies on the movement of the valve disc on the valve seat to control the flow of fluid. The valve disc moves linearly along the centerline of the valve seat, changing the distance between the valve disc and the valve seat, thereby changing the cross-sectional area of ​​the flow channel and achieving flow control and cutoff. In practical applications, gate valves are difficult to effectively filter impurities in the fluid. These impurities tend to accumulate in the valve body, causing blockage of the gate valve. This not only affects the normal operation of the valve, but also makes it inconvenient to clean the impurities. Utility Model Content

[0003] The purpose of this utility model is to provide a gate valve that facilitates the handling of impurities, thereby solving the problem mentioned in the background art that it is difficult to effectively filter impurities in the fluid during the actual application of gate valves. These impurities are prone to accumulate in the valve body, causing blockage of the gate valve, which not only affects the normal operation of the valve, but also makes it inconvenient to clean the impurities.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shut-off valve for convenient impurity handling, comprising a valve body, wherein a first filter screen is disposed inside the valve body, and a second filter screen is disposed on the inner side of the valve body. A scraper is rotatably connected to one side of both the first and second filter screens, and a rotating rod is disposed between the two scraper plates. The rotating rod is rotatably connected to the first filter screen. A maintenance groove is provided inside the valve body to cooperate with the first and second filter screens. A threaded through hole is provided at the bottom of the maintenance groove, and a threaded sealing post is threadedly connected to the inner side of the threaded through hole. A cover is provided at the bottom of the threaded sealing post.

[0005] As a preferred embodiment of this utility model: a side fixing box is rotatably connected to the outer side of the rotating rod, one side of the side fixing box is fixedly connected to the No. 1 filter screen, a worm gear is fixedly connected to the outer side of the rotating rod, a worm is rotatably connected to the inside of the side fixing box, and the worm is rotatably connected to the valve body.

[0016] 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.

[0017] Please refer to Figures 1 to 4. This utility model provides a technical solution: a stop valve for convenient impurity handling, including a valve body 1. A first filter screen 3 is fixedly connected inside the valve body 1, and a second filter screen 4 is fixedly connected to the inner side of the valve body 1. A scraper 9 is rotatably connected to one side of both the first filter screen 3 and the second filter screen 4. A rotating rod 6 is fixedly connected between the two scraper plates 9. The rotating rod 6 is rotatably connected to the first filter screen 3. A maintenance groove 16 is provided inside the valve body 1 to cooperate with the first filter screen 3 and the second filter screen 4. A threaded through hole 13 is provided at the bottom of the maintenance groove 16. A threaded sealing post 14 is threadedly connected to the inner side of the threaded through hole 13. A cover 15 is fixedly connected to the bottom of the threaded sealing post 14. By rotating the threaded sealing post 14 through the cover 15, the threaded sealing post 14 can be removed from the threaded through hole 13, and the impurities in the maintenance groove 16 can be cleaned.

[0018] The rotating rod 6 is rotatably connected to a side fixing box 5 on its outer side. One side of the side fixing box 5 is fixedly connected to the first filter screen 3. The rotating rod 6 is fixedly connected to a worm gear 7 on its outer side. The side fixing box 5 is rotatably connected to a worm 8 inside. The worm 8 is rotatably connected to the valve body 1. When the worm 8 rotates, it drives the meshing worm gear 7 to rotate. When the worm gear 7 rotates, it drives the inner rotating rod 6 to rotate. The rotating rod 6 drives the scraper 9 on one side of the first filter screen 3 and the second filter screen 4 to rotate, thereby scraping away the impurities on one side of the first filter screen 3 and the second filter screen 4.

[0019] The valve body 1 is equipped with a motor 11, the output end of which is fixedly connected to the worm gear 8. A maintenance plate 12 is bolted to the top of the valve body 1. The maintenance plate 12 has a wire hole inside, which protects the motor 11 and allows wiring to be done.

[0020] Among them, the top of the side fixed box 5 is symmetrically fixedly connected with a fixed bracket 10, the top of the fixed bracket 10 is fixedly connected to the valve body 1, and the side fixed box 5 is fixedly supported by the fixed bracket 10.

[0021] The threaded sealing post 14 is provided with a rubber sealing material on its outer side. By providing a rubber sealing material on the outer side of the threaded sealing post 14, the sealing effect of the threaded connection between the threaded sealing post 14 and the threaded through hole 13 is further improved, and leakage is avoided.

[0022] The valve body 1 has multiple observation windows 2 fixedly connected to its top, allowing for observation of impurities inside the valve body 1 and facilitating maintenance.

[0023] Specifically, during use, water entering the valve body 1 is filtered through the first filter screen 3, and then through the second filter screen 4 for secondary filtration to remove impurities. The output of the motor 11 drives the worm gear 8 to rotate, which in turn drives the meshing worm wheel 7 to rotate and adjust. When the worm wheel 7 rotates, it drives the inner rotating rod 6 to rotate, which in turn drives the scraper plates 9 at both ends to rotate synchronously. The scraper plates 9 scrape away impurities on one side of the first filter screen 3 and the second filter screen 4, ensuring the filtration effect of the first filter screen 3 and the second filter screen 4 and preventing clogging. When maintenance is required, the water supply is stopped, and the cover 15 is rotated. When the cover 15 rotates, it drives the threaded sealing post 14, which is threadedly connected to the threaded through hole 13. The threaded sealing post 14 and the cover 15 are removed from the valve body 1, and can be inserted into the maintenance groove 16 for impurity cleaning. The condition inside the valve body 1 can be observed through the observation window 2 for convenient maintenance and cleaning.
