Description

Technical Field

[0001] The utility model relates to a water valve structure, in particular to a water valve structure with a water inlet filtering function, belonging to the technical field of valves. Background Art

[0002] Valves are key control components in fluid delivery systems, used to open and close pipelines, control flow direction, and adjust parameters of the delivery medium (such as temperature, pressure, and flow). There are many types of valves, which can be divided into shut-off valves, check valves, and regulating valves according to their functions; and various materials including cast steel, stainless steel, and plastic according to their materials. Valves have multiple functions such as shutoff, regulation, flow diversion, backflow prevention, and voltage stabilization, and are widely used to control the flow of various types of fluids such as water, steam, oil, and gas. In industrial production, valves are indispensable pipeline accessories, and their performance and quality directly affect the safety and efficiency of fluid delivery systems.

[0003] In order to filter impurities in water supply pipelines, filters are usually installed on valves. After long-term use, impurities will accumulate on the filters. Therefore, it is necessary to close the valve and take out the filters for cleaning. The filter cleaning may take a certain amount of time. Users cannot use water during the cleaning process. Especially for some main valves, cleaning will cause a large number of users to be unable to use water. Utility Model Content

[0022] The embodiment of the present utility model provides a water valve structure with an inlet water filtering function.

[0023] Please refer to Figure 1 and Figure 2 , a water valve structure with an inlet water filtering function, including a valve body 1, docking nuts 2 are provided at both ends of the valve body 1, a valve stem 4 is provided on the valve body 1, a handle 3 is connected to the valve stem 4, a filtering mechanism 5 is provided on the valve body 1, the filtering mechanism 5 includes a filter screen outlet 501 and a plunger inlet 506 provided on the valve body 1, a filter screen 507 is provided in the valve body 1, sealing pistons 502 are fixedly installed at both ends of the filter screen 507, a cleaning mechanism 6 is provided in the plunger inlet 506, the filtering mechanism 5 can filter the water in the pipeline, and when cleaning the filter screen, the water will pass through the temporary water passage hole 607, ensuring that users can use water normally while cleaning the filter screen 507.

[0024] Please refer to again Figure 2 and Figure 3 , the filtering mechanism 5 includes a filter screen outlet 501 and a plunger inlet 506 provided on the valve body 1, a filter screen 507 is provided in the valve body 1, sealing pistons 502 are fixedly installed at both ends of the filter screen 507, a movable shaft 504 is movably installed between the sealing pistons 502, a cleaning scraper 503 is fixedly installed on the movable shaft 504, and the filtering mechanism 5 further includes a sealing ring 505 provided on the sealing piston 502.

[0025] Specifically, the moisture in the pipeline can be filtered through the filter screen 507. During the filtering process, the sealing piston 502 will block the filter screen outlet 501 and the plunger inlet 506 to prevent the leakage of moisture in the valve body 1. At the same time, when the handwheel 606 is rotated, the driving screw 605 will drive the transmission shaft 608 to rotate, thereby driving the cleaning scraper 503 on the movable shaft 504 to rotate and scrape off the impurities on the surface of the filter screen.

[0026] Please refer to again Figure 2 and Figure 4 Specifically, the cleaning mechanism 6 includes a driving screw 605 threadedly installed on the plunger inlet 506. The lower end of the driving screw 605 is fixedly installed with a handwheel 606. The upper end of the driving screw 605 is rotatably connected to a sealing plunger 601. A temporary water passage hole 607 is provided in the sealing plunger 601. A temporary filter screen 602 is provided in the temporary water passage hole 607. A transmission shaft 608 is provided between the driving screw 605 and the movable shaft 504. The cleaning mechanism 6 further includes a rotary connection seat 604 provided at the bottom of the sealing plunger 601. An installation port 603 is provided on the side wall of the plunger inlet 506, and the installation port 603 is aligned with the temporary water passage hole 607 on the sealing plunger 601.

[0027] Specifically, by rotating the handwheel 606, the driving screw 605 can be driven to extend into the valve body 1, thereby lifting the sealing plunger 601 and moving the sealing plunger 601 to the middle position of the valve body 1. After the sealing plunger 601 moves to the middle position of the valve body 1, the filter screen 507 will move to the outside of the valve body 1 through the filter screen outlet 501, facilitating the user to clean. During the cleaning process, the moisture will pass through the temporary water passage hole 607, ensuring that the user can use water normally while cleaning the filter screen 507, and the temporary filter screen 602 can filter the moisture passing through the temporary water passage hole 607.

[0028] Working principle: When in use, install the valve body 1 on the pipeline. After turning the handle 3, the valve can be controlled to open. After the valve is opened, the water flow will pass through the filter screen 507, thereby filtering the water in the pipeline. During the filtering process, the sealing piston 502 will block the filter screen outlet 501 and the plunger inlet 506, thereby preventing the leakage of water in the valve body 1. After long-term use, impurities will accumulate on the filter screen 507. After impurities accumulate on the filter screen 507, the handwheel 606 can be rotated. After rotating the handwheel 606, it will drive the drive screw 605 to extend into the valve body 1. After the drive screw 605 extends into the valve body 1, it will lift the sealing plunger 601, causing the sealing plunger 601 to move to the middle position of the valve body 1. After the sealing plunger 601 moves to the middle position of the valve body 1, the filter screen 507 will move to the outside of the valve body 1 through the filter screen outlet 501, facilitating the user to clean it. And during the cleaning process, the water will pass through the temporary water passing hole 607, ensuring that the user can use water normally while cleaning the filter screen 507. When the water passes through the temporary water passing hole 607, the temporary filter screen 602 can filter the water. At the same time, when the handwheel 606 is rotated, the drive screw 605 will drive the transmission shaft 608 to rotate. After the transmission shaft 608 rotates, it will drive the cleaning scraper 503 on the movable shaft 504 to rotate, thereby scraping off the impurities on the surface of the filter screen when the filter screen 507 is taken out.
