Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically to a ball valve with a self-cleaning function. Background Technology

[0002] A ball valve is a valve in which the valve stem drives the valve to rotate around the valve axis. It can also be used for fluid regulation and control. Among them, the hard-seal V-type ball valve has a strong shearing force between the V-shaped ball core and the metal valve seat with hard alloy overlay, making it particularly suitable for media containing fibers, small solid particles, etc.

[0003] However, many existing ball valves accumulate a lot of impurities inside after prolonged use. If these impurities cannot be filtered out in time during transmission, they will stick to the inner wall of the valve body. Over time, this sticking will affect the use of the ball valve and its service life to some extent. Utility Model Content

[0004] This utility model proposes a ball valve with a self-cleaning function. By setting up a filter pipe, mounting box, mounting groove, mounting plate and filter screen, it is possible to filter impurities contained in the liquid entering the ball valve, thereby reducing the impurities adhering to the inner wall of the valve body, thus ensuring the use of the ball valve to a certain extent and solving the above-mentioned problems.

[0024] like Figures 1-5 As shown, this embodiment proposes a ball valve with a self-cleaning function, including a valve body 1, a filter pipe 2 arranged on the left side of the valve body 1, flanges 3 fixedly installed on both sides of the valve body 1 and the filter pipe 2, each flange 3 having a mounting through hole 4, a mounting box 5 fixedly installed on the filter pipe 2, a mounting groove 6 opened at the top of the mounting box 5, a mounting plate 7 slidably installed inside the mounting groove 6, a grooved handle 8 opened at the top of the mounting plate 7, a filter screen 9 fixedly installed on the mounting plate 7, and a mounting strip 12 rotatably installed at the rear end of the top of the mounting box 5, a spring groove 13 opened at the bottom end of the mounting strip 12, and a spring... A pressure strip 14 is slidably installed inside the spring groove 13. Several sets of first springs 15 are fixedly installed at the top of the spring groove 13. The other end of each set of first springs 15 is fixedly connected to the pressure strip 14. A handle 16 is fixedly installed at the top of the mounting strip 12. A sliding hole 17 is opened horizontally at the front left side of the mounting box 5. A limit rod 18 is slidably installed through the sliding hole 17. A second spring 20 is sleeved on the limit rod 18. The left side of the second spring 20 is fixedly connected to the fixing plate 19, and the right side of the second spring 20 is fixedly connected to the mounting box 5. A limit through hole 21 corresponding to the limit rod 18 is opened on the mounting strip 12.

[0025] A first sealing gasket is fixedly installed at the connection between the outer surface of the mounting plate 7 and the mounting groove 6; a sliding strip 10 is vertically fixedly installed on the outer wall of both the front and rear ends of the mounting plate 7, and a sliding groove 11 is vertically opened on the inner wall of both the front and rear ends of the mounting groove 6; the cross-sections of the two sets of sliding strips 10 and the two sets of sliding grooves 11 are trapezoidal; the number of mounting through holes 4 opened on each flange 3 is six, and they are all opened in a ring array on the flange 3; a valve stem 22 is provided at the top of the valve body 1, and a rotating ring 23 is fixedly installed at the top of the valve stem 22.

[0026] In this embodiment, the filter screen 9, which is fixedly installed on the mounting plate 7, can filter impurities contained in the liquid entering the ball valve, thereby reducing impurities adhering to the inner wall of the valve body. This ensures the use of the ball valve to a certain extent and also reduces the impact of impurities on the service life of the ball valve.
