Problems solved by technology

[0003] The inside of the traditional diaphragm valve is provided with a sealing reinforcement convex diameter, so that when the sealing convex diameter is in contact with the valve body, it is easy to form a slit stagnation area in the convex diameter, causing internal pollution of the valve body. Therefore, we propose a diaphragm valve without dead angle. Solve the above problems

Abstract

The invention relates to a pneumatic diaphragm valve. The diaphragm valve includes an indication cover, an actuator, a valve stem, a valve cover, a valve element, a diaphragm, a valve body, a nut anda screw; and the actuator is arranged on the top of the diaphragm valve, the upper part of the actuator is provided with the indication cover, the valve cover is arranged at the lower portion of the actuator through a connecting member, the valve element is arranged in the valve cover, the valve element is in a bowl shape, the diaphragm is arranged at the lower portion of the valve element, the valve stem is vertically arranged in the valve cover, the valve body is arranged at the lower portion of the valve cover, the diaphragm is arranged between the valve body and the valve cover for filling, and the valve body and the valve cover are fixedly connected through the nut and the screw. The pneumatic diaphragm valve is simple in structure, can achieve two-way circulation, enables the inner surface to be clean and is good in sealing performance, simple in operation, low in production cost and long in service life.

Description

technical field [0001] The invention relates to a pneumatic valve, in particular to a pneumatic diaphragm valve. Background technique [0002] The structure of the diaphragm valve is very different from that of the general valve. It relies on a soft rubber or plastic film to control the movement of the fluid. Commonly used diaphragm valve materials are divided into cast iron diaphragm valves, cast steel diaphragm valves, stainless steel diaphragm valves, and plastic diaphragm valves. [0003] The inside of the traditional diaphragm valve is provided with a sealing reinforcement convex diameter, so that when the sealing convex diameter is in contact with the valve body, a slit stagnation area is easily formed in the convex diameter, causing internal pollution of the valve body. Therefore, we propose a diaphragm valve without dead angle. Solve the above existing problems. Contents of the invention [0004] In order to solve the above problems, the present invention provide...
