[0002] With the progress of the times and the development of science and technology, the application of chemical engineering has gradually attracted people's attention. Pipe valves are one of the essential pieces of equipment in chemical equipment and facilities. Chemical valves are important accessories for controlling the flow of media in chemical pipelines. They are used to regulate the flow rate and adjust the opening and closing of the flow path in chemical liquid transportation pipelines.

[0003] Currently, in existing chemical pipeline valves, impurities easily accumulate in the valve core, causing blockage and affecting service life. Therefore, it is necessary to provide an anti-clogging chemical pipeline valve to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a valve for preventing blockage in chemical pipelines.

[0014] Example 1 like Figures 1-5As shown, the anti-clogging chemical pipe valve of this utility model includes a pipe valve body 1, a valve stem fitting 16 on the pipe valve body 1, a threaded valve stem 18 rotatably connected inside the valve stem fitting 16, a movable partition plate 19 fixedly connected to the threaded valve stem 18 and slidably connected inside the valve stem fitting 16, a stop valve core 20 adapted to the pipe valve body 1 fixedly connected to the bottom of the threaded valve stem 18, a valve stem handle 17 fixedly connected to the top of the threaded valve stem 18, and an anti-clogging component inside the pipe valve body 1; the anti-clogging component includes components that penetrate the bottom of the pipe valve body 1 and are slidably connected inside the pipe valve body 1. The filter screen 10 has a locking and fixing component at its bottom. The valve body 1 has a sealing groove 13 and a slot 11 that are adapted to the filter screen 10. The filter screen 10 is installed inside the valve body 1 to block impurities and prevent them from accumulating at the valve core. By pulling down the operating block 7, the filter screen 10 can be moved out of the valve body 1 housing 5, which facilitates regular cleaning of the filter screen 10 to prevent clogging. This solves the technical problem in the prior art where impurities easily accumulate at the valve core during the use of chemical valves, causing valve clogging and affecting service life.

[0015] The locking and fixing assembly includes a housing 5 located at the bottom of the valve body 1 and slidably connected to the filter screen 10, an operating block 7 fixedly connected to the bottom of the housing 5 and the filter screen 10, a rubber sealing plug 9 corresponding to the valve body 1 and the housing 5 on the operating block 7, and a locking block 8 adapted to the operating block 7 rotatably connected to the housing 5. The locking block 8 is rotatably connected to the housing 5 through a rotating shaft 12, and a torsion spring 14 adapted to the locking block 8 is sleeved on the rotating shaft 12. The elastic force of the torsion spring 14 is used to lock the locking block 8 connected to it through the rotating shaft 12 to the bottom of the operating block 7, thereby restricting the position of the operating block 7, the fixing block 15, the rubber sealing plug 9 and the filter screen 10, preventing them from detaching and ensuring sealing.

[0016] The operating block 7 is provided with a fixing block 15 that is adapted to the box body 5.

[0017] Both ends of the valve body 1 are provided with connectors 6. Multiple fixing holes 3 are evenly opened on the connectors 6. Grooves 4 are opened on the connectors 6, and rubber sealing rings 2 are provided in the grooves 4.

[0018] The thickness of the rubber sealing plug 9 is greater than the thickness of the filter screen 10, and the fixing block 15 and the operating block 7 are integrally formed.

[0019] Working process or working principle: In use, the filter screen 10 is used to filter impurities from the flowing liquid to prevent them from settling at the valve core. When the filter screen 10 needs to be removed, first cut off the liquid flow into the valve body 1, then rotate the locking block 8 after the liquid in the valve body 1 has been removed. This causes the torsion spring 14 to deform elastically, allowing the locking block 8 to release its restriction on the position of the operating block 7. Then, pull the operating block 7 down to move the filter screen 10, which is connected to it by the fixing block 15 and the rubber sealing plug 9, out of the valve body 1 housing 5. Since the thickness of the rubber sealing plug 9 is greater than the thickness of the filter screen 10, impurities on the filter screen 10 can be removed along with it. Moreover, after closing the stop valve core 20, if the liquid continues to flow into the valve body 1, impurities can be discharged from the sealing groove 13.

[0020] This invention features a filter screen 10 inside the valve body 1, which can block impurities and prevent them from accumulating at the valve core. By pulling down the operating block 7, the fixed block 15 connected to it moves the rubber sealing plug 9 and the filter screen 10 out of the valve body 1 and the box 5, thus facilitating regular cleaning of the filter screen 10 and preventing clogging. This invention solves the technical problem in the prior art where impurities easily accumulate at the valve core during the use of chemical valves, causing valve blockage and affecting service life.

[0021] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
