Among them, butterfly valves are widely used in gas-solid transportation pipeline systems. Butterfly valve, also known as flap valve, is a valve that uses disc-type opening and closing parts to turn back and forth from 0 to 90° to realize closing, opening and regulating flow. It has the advantages of simple structure, small size and convenient operation. It is widely used in industrial fields. The application is very extensive. During the use of the butterfly valve, the seal is mainly achieved by the tight fit between the outer circumference of the valve plate and the inner wall of the valve, but due to the small contact area and continuous wear and tear, weak points of the seal are prone to appear on the joint surface, resulting in leakage Occurs, affecting the use effect.
针对以上问题，申请人进行了研究，提供了一种经过改进的防漏效果好的蝶阀。In view of the above problems, the applicant conducted research and provided an improved butterfly valve with good leak-proof effect.
