Abstract

The present invention discloses a blow-down valve. The blow-down valve comprises a valve seat, a pipe joint, a filter screen, crushing blades and a second air bag, a valve body is installed at the upper end of the valve seat, a connector is arranged on the outer side of the valve seat, the pipe joint is arranged on the outer side of the connector, a limiting column is arranged on the outer side ofthe right end of the pipe joint, and a connecting shaft is connected to a middle bearing of the filter screen; crushing blades and a micro impeller are fixed to the upper end and the lower end of theconnecting shaft through bolts correspondingly, a blow-off pipe is arranged on the outer side of the pipe connector, a limiting groove is formed in the surface of the connecting column, a movable ring is arranged on the outer side of the connector, a linkage block is arranged on the inner side of the connector, a containing groove is formed in the connector, and a containing groove is formed in the end face of the connector. The blow-down valve can be conveniently and stably installed, is convenient to disassemble and maintain in the later period, and can automatically cut and crush impurities in sewage to prevent the valve from being blocked.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a blowdown valve. Background technique [0002] With the development of economy and science and technology, my country's maritime military power has been greatly developed and improved, and has made great contributions to defending the country's territorial integrity. Among them, warships are an indispensable part of maritime military weapons. In combat, when warships perform tasks, they often need to sail at sea for several months. Therefore, while ensuring military combat effectiveness, warships also need to protect the sea life of the crew. Among them, vacuum toilets are indispensable living utensils on warships. During the use of vacuum toilets, It is necessary to use the blowdown valve to realize vacuum blowdown, but the existing blowdown valve still has certain defects in use: [0003] 1. Most of the existing sewage valves and sewage pipelines are connected by bolted flanges,...
