Abstract

The invention discloses a pipe pressure type explosion suppression valve which comprises a pipe pressure valve and an air storage valve. The pipe pressure valve is communicated with the air storage valve through a pipe, a pulse electromagnetic valve is arranged on the pipe for communicating the pipe pressure valve and the air storage valve, a first electromagnetic valve is arranged on an inlet pipe of an air storage tank, and a pressure sensor for detecting air pressure inside the air storage tank is arranged on the air storage tank and connected with the first electromagnetic valve; and a second electromagnetic valve is arranged on an outlet pipe of the pipe pressure valve, the pulse electromagnetic valve is connected with a front section sensor used for detecting explosion signals, and the front section sensor is connected with the second electromagnetic valve. During normal work, the pipe pressure type explosion suppression valve is in the opening state; when explosion happens, the front section sensor detects the explosion signals, and signals are sent out to control opening of the pulse electromagnetic valve, the second electromagnetic valve is closed, gas in the air storage tank is injected into the pipe pressure valve, the pipe pressure valve is closed to isolate explosion, and downstream persons and equipment are protected.

Description

technical field [0001] The invention belongs to a pipe pressure type explosion-proof valve, and more specifically relates to a pipe pressure type explosion-proof valve for isolating explosions. Background technique [0002] With the development of the national economy, several large dust explosion accidents have occurred in our country, causing heavy casualties and property losses. At present, there is no explosion isolation device in the dust pipeline transmission, which cannot cut off the propagation of explosion shock wave and flame, which is easy to cause greater losses. Contents of the invention [0003] The object of the present invention is to provide a pipe pressure type explosion-proof valve for blocking explosion. [0004] According to one aspect of the present invention, a pipe pressure type explosion-proof valve is provided, including [0005] A gas storage tank, the inlet pipe of the gas storage tank is provided with a first electromagnetic valve, the tank b...
