Abstract

The invention relates to the technical field of blow-down valves, in particular to a pull-fastened vacuum barrier-free blow-down valve comprising a plastic body (8), a pair of end plates (1), a rubber sealed hose (2), a pair of seals (3), a pair of cover plates (4), a pair of springs (5), a first piston (6) and a second piston (7). The plastic body (8) is provided with an air access (111), a pair of outer protrusions and a pair of inner protrusions. The end plates (1) are mounted on the outer protrusions arranged at two ends of the plastic body (8). The two ends of the rubber sealed hose (2) hermetically sleeve the inner protrusions of the plastic body (8), respectively. The cover plates (8) are both mounted on the plastic body (8) and sealed with the seals (3). The pull-fastened vacuum barrier-free blow-down valve is controlled via vacuum air provided by a system, is rarely damaged, is lower in application cost and is rarely jammed.

Description

technical field [0001] The invention relates to the technical field of blowdown valves, in particular to a pull button type vacuum unobstructed blowdown valve. Background technique [0002] The sewage valve is a valve driven by a solenoid valve or compressed air. Most of the existing sewage valves are made of metal, which is expensive and heavy, and the sealing part is sealed by extrusion between the diaphragm and the metal valve body. The diaphragm is easily damaged, resulting in frequent leakage, troublesome replacement, and high maintenance costs. In addition, the channel sealed by the diaphragm is not directly connected to the sewage pipe, which changes the flow direction of sewage, creates resistance, hinders the passage of sewage, and is prone to blockage. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems, and to provide a pull button type vacuum unobstructed sewage valve. [0004] The invention includes...
