Problems solved by technology

[0002] Pinch valve is a kind of valve often used by chemical and mining enterprises. The inside of the valve is a rubber bushing. According to the control mode, it is divided into manual, pneumatic, electric and other varieties. It has a large amount of use and is widely used. Among them, the air control clamp Due to the poor sealing of pipe valves, air leakage often occurs when the rubber sleeve cannot be tightened at the flange part, resulting in the valve sleeve being unable to close. In addition, the valve lining pressure is low, it is easy to burst, it is not wear-resistant, and its service life is short. Replacement frequently

Abstract

The invention relates to a pneumatic control valve which comprises a valve body and a valve element arranged in the inner cavity of the valve body. The valve body comprises a shell body, an upper tubular inner cavity, an elliptic inner cavity, a lower tubular inner cavity and an air inlet, the upper tubular inner cavity, the elliptic inner cavity and the lower tubular inner cavity are arranged in sequence and are communicated in sequence, the air inlet is formed in the shell body, the air inlet is formed in the cavity wall of the elliptic inner cavity, and the valve element is provided with a middle through hole, a wear-resisting rubber layer and a tyre fabric reinforcement layer from inside to outside in sequence. The pneumatic control valve is good in sealing effect, the wear resistance of the valve element is good, the service life is long, and bearing pressure is high. The problem that the pneumatic control valve is poor in sealing or the valve element is easy to pull out is solved, the structure is simplified, and processing difficulty is lowered. The problems that an existing pneumatic control valve element is not resistant to wear and bearing pressure is low are solved.
