Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to an anti-clogging butterfly valve. Background Art

[0002] The anti-clogging butterfly valve is a valve used to control the flow of fluid media. It is designed to reduce or prevent the accumulation of solid particles or impurities inside the pipeline or valve to prevent valve clogging and ensure the normal operation of the fluid system. This valve is usually used in industrial fields that need to handle fluid media containing solid particles, such as sewage treatment, chemical production, food processing, etc. In many industrial processes, the accumulation and clogging of solid particles are common problems, which will lead to pipeline or equipment failure, production interruption and equipment damage, seriously affecting production efficiency and product quality. Therefore, designing an anti-clogging butterfly valve has become an important way to solve this problem.

[0003] After searching, the existing patent (Announcement No.: CN213419914U) discloses an anti-clogging butterfly valve, including a hand wheel, a valve body, a valve plate, a rotating shaft and a shaft seat, the bottom end of the valve body is fixed with a shaft seat, both sides of the valve body are equipped with sealing rings, a protective shell is fixed at the middle position of the top of the valve body, the outer walls on both sides of the fixed shaft are provided with rotating shafts, and the outer walls of the rotating shaft are evenly fixed with crushing leaves. The utility model arranges a crushing structure on both sides of the inside of the butterfly valve, and the flow of the fluid will drive the crushing leaves on the structure to rotate. When larger impurities pass through the crushing device, they will be cut off by the rotating crushing leaves, so that the impurities cannot gather inside the butterfly valve and cause blockage inside the butterfly valve, which provides a guarantee for the normal operation of the butterfly valve, and well solves the problem of malfunction caused by the blockage of the butterfly valve, which requires the disassembly of the pipes on both sides of the butterfly valve for dredging and maintenance, thereby improving the practicality of the butterfly valve.

[0004] However, in the actual use of the above scheme, the impurities will still remain in the pipeline after being crushed by the crushing blades, and it is difficult to clean them. Impurities that are difficult to clean may hinder the normal flow of the fluid, reduce the processing capacity of the valve, and affect the normal operation of the industrial production process. Utility Model Content

[0005] The utility model provides an anti-clogging butterfly valve, which solves the problem of difficulty in cleaning impurities.

[0006] The technical solution of the utility model is as follows: an anti-clogging butterfly valve comprises a water inlet pipe, a connecting pipe is fixedly connected to the right bottom end of the water inlet pipe, a filter tube is fixedly connected to the inner side of the connecting pipe, a fixing nut is threadedly connected to the outer side of the bottom end of the filter tube, a sealing nut is threadedly connected to the inner side of the bottom end of the filter tube, a connecting rod is fixedly connected to the top end of the sealing nut, and evenly distributed cleaning plates are fixedly connected to the outer side of the top end of the connecting rod.

[0007] Preferably, the cleaning plate is slidably connected to the filter tube.

[0008] Preferably, a connecting flange is fixedly connected to the left outer end of the water inlet pipe, and a valve body is fixedly connected to the left side of the connecting flange.

[0009] Preferably, a first sealing plate is fixedly connected to the top end of the valve body, and a transmission column is rotatably connected to the inner side of the first sealing plate.

[0012] Preferably, the transmission column is rotatably connected to the valve body.

[0013] Preferably, the handle is rotatably connected to the first sealing plate.

[0014] The working principle and beneficial effects of the utility model are as follows: when the anti-clogging butterfly valve is used, liquid first enters through the right side of the water inlet pipe, is transported into the filter tube, and the liquid is filtered through the filter holes opened on the inner wall of the filter tube. At the same time, impurities are filtered out and retained in the filter tube, thereby preventing the valve body from being clogged. By filtering the liquid through the filter tube, solid particles or impurities in the liquid can be effectively removed, and the chance of these particles entering the valve can be reduced, thereby reducing the risk of valve clogging, reducing the wear and damage of the internal structure of the valve by solid particles, extending the service life of the valve, and reducing maintenance costs.
