Abstract

The invention discloses a pipe pressure type explosion-proof valve, which comprises a pipe pressure valve and a gas storage tank. The pipe pressure valve and the gas storage tank are connected through a pipeline. The inlet pipe of the gas tank is provided with a first solenoid valve, and the gas storage tank is provided with a pressure sensor for detecting the internal pressure of the gas storage tank. The pressure sensor is connected with the first solenoid valve, and the outlet pipe of the pipe pressure valve is provided with a second valve. The electromagnetic valve, the pulse electromagnetic valve is connected with the front sensor for detecting the explosion signal, and the front sensor is connected with the second electromagnetic valve. When working normally, the pipe pressure type explosion-proof valve is in the open state; when the explosion occurs, the front sensor detects the explosion signal, then sends out a signal to control the pulse solenoid valve to open, the second solenoid valve closes, and the gas in the gas storage tank is poured into the pipe. In the pressure valve, the pipe pressure valve is closed to isolate the explosion and protect people and equipment downstream.

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...
