Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, and in particular to an anti-clogging butterfly valve. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve used for on / off control of low-pressure pipeline media. A butterfly valve is a type of valve where the closing element is a disc that rotates around the valve shaft to open and close. Butterfly valves can control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. In pipelines, they primarily function as shut-off and throttling devices. The butterfly valve's opening and closing element is a disc-shaped butterfly plate that rotates around its own axis within the valve body to achieve opening, closing, or regulation.

[0003] In the existing valve plate structure, when the liquid contains impurities during opening and closing, the space for impurities to pass through the valve plate becomes smaller, causing impurities on the outside to be trapped on both sides of the valve plate. If this is not cleaned for a long time, it will cause blockage in the flow channels on both sides of the valve plate, which requires treatment. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-clogging butterfly valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-clogging butterfly valve includes a valve body, a flange, and a valve plate. The valve plate is movably disposed inside the valve body. An inner groove is formed inside the valve plate. An electric push rod is disposed in the middle of the inner groove. The output end of the electric push rod is connected to a rotary motor. The output end of the rotary motor is connected to an output rod. Two mounting seats are provided at one end of the output rod. Anti-clogging scraper one and anti-clogging scraper two are respectively installed on the outer sides of the two mounting seats.

[0007] Preferably, one end of the output rod is provided with a threaded head, the threaded head is externally threaded with a threaded sleeve, and an arc-shaped rubber sheet is provided on the outer side of the threaded sleeve.

[0008] Preferably, the inner wall of the inner groove is provided with a support end face, and the inner side of the arc-shaped rubber sheet is pressed against the support end face.

[0009] Preferably, a valve seat is provided at the top of the valve body, a valve stem is provided inside the valve seat, a valve stem seat is provided at the top of the valve plate, and the bottom end of the valve stem is fixed inside the valve stem seat. Rotating the lever drives the valve stem inside the valve seat to rotate through the transmission gear, which in turn drives the valve plate to rotate, opening the valve plate and thus opening the flow channel. The transmission gear and lever transmission principle and structure of this application are all existing publicly disclosed technologies. In this application, we are only using them without making any structural or functional improvements, and we will not elaborate on them here.

[0010] Preferably, flanges are provided on both sides of the valve body, and two sealing strips are provided on the outer side of the valve plate. The two ends of the valve body are connected to the external pipeline through the flanges to realize installation. The two sealing strips on the outer side of the valve plate can improve the sealing performance of the valve plate.

[0011] Preferably, a transmission seat is provided on the top of the valve seat, and a handle is provided on one side of the transmission seat.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This application features an output rod driven by a rotary motor and two anti-clogging scrapers mounted on the output rod inside the valve body. When the valve plate is open and the flow channel on its side becomes blocked, the anti-clogging scrapers can be pushed by an electric push rod. The arc-shaped rubber sheet at the front end of the anti-clogging scraper is pressed against the inner wall of the valve body. At the same time, the anti-clogging scrapers are placed inside the flow channel. In this way, the rotary motor can drive the anti-clogging scrapers to rotate, thereby causing them to rotate and scrape away the blockage, effectively removing debris from the blockage site and relieving the blockage, thus achieving the anti-clogging effect of the butterfly valve.
