Abstract

The invention relates to a membrane type quick-opening sludge drainage valve comprising a valve body, a membrane base and a valve deck. An inlet is formed in one side of the valve body. An outlet is formed in the bottom of the valve body. A valve clack is arranged in the valve body. A membrane piece is arranged between the bottom end of the valve deck and the top end of the membrane base. A water pressure cavity is formed between the membrane piece and the valve deck. A matching cavity is formed between the membrane piece and the membrane base. An upper membrane pressing plate and a lower membrane pressing plate are arranged on the upper face and the lower face of the membrane piece correspondingly. A through hole is formed in the bottom of the membrane base. A valve rod is connected with the valve clack. The upper end of the valve rod penetrates the through hole of the membrane base to be connected with the membrane piece, the upper membrane pressing plate and the lower membrane pressing plate. A water inlet and a water outlet are formed in the top of the valve deck. A filter is arranged at the position of the water inlet and communicates with the inlet end of the valve body through a connection pipe. A pressure balance hole communicating with the outside world is formed in the matching cavity. Compared with the prior art, the membrane type quick-opening sludge drainage valve has the beneficial effects of being good in operability, long in service life, low in installation cost and the like.
