Description

Technical Field

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

[0002] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can be used for the regulation and control of fluids and is widely used in industries such as chemical, water conservancy, and power. The valve body is the main component of the ball valve and is usually made of metal materials to house the valve parts and the medium inside the valve.

[0003] The existing patent document CN217108458U discloses a ball valve with a self-cleaning function. This utility model has a support frame provided inside both the first and second valve chambers. When the valve body transmits water flow, some impurities will be mixed in with the water flow. During the transmission process, the water flow will pass through the internal adsorption net. The water flow will penetrate the adsorption net, and the mixed impurities will stick to the outer wall of the adsorption net, thereby blocking the impurities in time. It is very convenient to use.

[0004] However, existing ball valves with self-cleaning functions do not provide good buffering protection for the adsorption net during use. When filtering fluids, the fluid in the existing ball valve will bring a certain impact force to the adsorption net during the transportation process. If it is not buffered, it will easily cause wear to the adsorption net structure, directly affecting the service life and filtration effect of the adsorption net, and its practicality is poor. Utility Model Content

[0024] 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.

[0025] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a ball valve with self-cleaning function, including a ball valve body 1, a first valve chamber 2 is provided on one side of the ball valve body 1, a second valve chamber 3 is provided on the side of the ball valve body 1 away from the first valve chamber 2, a filter mechanism 4 is provided inside the first valve chamber 2, a sealing mechanism 5 is provided on the outside of the first valve chamber 2, and a connecting mechanism 6 is provided above the first valve chamber 2.

[0026] The filtration mechanism 4 includes a U-shaped positioning seat 401, which is located inside the first valve chamber 2. An adsorption net 402 is movably connected inside the U-shaped positioning seat 401. A buffer spring 403 is fixedly connected to one side of the U-shaped positioning seat 401. A positioning clamp 404 is fixedly connected to the side of the buffer spring 403 away from the U-shaped positioning seat 401, located on one side of the adsorption net 402. During the use of the ball valve, fluid enters the first valve chamber 2, and the adsorption net 402 adsorbs fluid... Impurities are trapped and adsorbed. The filtered fluid flows into the second valve chamber 3 through the opening and closing of the ball valve body 1. During the flow of the fluid, a certain impact force is brought to the adsorption net 402. The adsorption net 402 is squeezed by the force and the positioning clamp 404 is compressed by the positioning clamp 404. The positioning clamp 404 compresses the buffer spring 403. The buffer spring 403 uses its elastic potential energy to buffer the impact force on the positioning clamp 404, thereby achieving shock absorption and protection for the adsorption net 402 and reducing the wear caused by fluid impact on the adsorption net 402.

[0027] The sealing mechanism 5 includes a support base 501, which is fixedly mounted on the upper surface of the first valve chamber 2. U-shaped positioning seats 401 are located on both sides inside the support base 501. A protective cover plate 502 is movably connected to the upper surface of the support base 501. A rectangular sealing gasket 503 is fixedly connected to one side of the protective cover plate 502. A sealing groove 504 is fixedly provided inside the support base 501. The rectangular sealing gasket 503 corresponds to the sealing groove 504 and is movably connected to it. A sealing plate 505 is fixedly connected to the side of the support base 501 closest to the rectangular sealing gasket 503. The connecting mechanism 6 includes a positioning groove 601, on which the protective cover plate 502 is fixedly mounted. On both sides of the upper surface, fastening bolts 602 are movably connected to the upper surface of the protective cover 502, and connecting grooves 603 are fixedly provided on both sides of the upper surface of the support base 501. The fastening bolts 602 are movably connected to the connecting grooves 603. When it is necessary to inspect, clean or replace the adsorption net 402, the operator can operate the fastening bolts 602 to separate them from the connecting grooves 603, thereby releasing the restriction on the protective cover 502. The operator can then pull the protective cover 502 to pull out the rectangular sealing gasket 503 from the sealing groove 504, thus disassembling the protective cover 502. The operator can then pull the adsorption net 402 out of the U-shaped positioning seat 401, thereby enabling the adsorption net 402 to be inspected or replaced.

[0028] Working principle: During the use of the ball valve, fluid enters the first valve chamber 2. The adsorption net 402 traps and adsorbs impurities in the fluid. The filtered fluid flows into the second valve chamber 3 through the opening and closing of the ball valve body 1. During the flow of the fluid, a certain impact force is exerted on the adsorption net 402. The adsorption net 402 is subjected to force that compresses the positioning clamp 404, which in turn compresses the buffer spring 403. The buffer spring 403 uses its elastic potential energy to buffer the impact force on the positioning clamp 404, thereby achieving shock absorption and protection for the adsorption net 402. To minimize wear and tear on the adsorption net 402 caused by fluid impact, when it is necessary to inspect, clean, or replace the adsorption net 402, the operator can operate the fastening bolt 602 to separate it from the connecting groove 603, thereby releasing the restriction on the protective cover plate 502. By pulling the protective cover plate 502, the operator can pull the rectangular sealing gasket 503 out of the sealing groove 504, thus disassembling the protective cover plate 502. By pulling the adsorption net 402, the operator can pull it out of the U-shaped positioning seat 401, allowing for inspection or replacement of the adsorption net 402.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
