Dust explosion proof positive pressure tank

Within the combustible dust environment using measuring instrument system and electric installation system, demand more and more. But simply rely on containment shell to solve the problem of explosion, it is only suitable for electrical components and low calorific value of electrical system less, for relatively large electrical system (electrical parts, large power, high calorific value), only rely on the sealed performance is good shell of explosion-proof electrical equipment, and its security can not meet the requirement, the feasibility is not high.
Its characteristics lies in the cabinet put oneself in another|s position structure including exhaust system, must be used to install explosion protection control system of the main tank, used to install ark of positive pressure control system of the deputy, among them, the ark of the Lord and deputy ark cabinet put oneself in another|s mutual independence and fixed connection, exhaust system in the main tank top, exhaust system, cable seal welding joints and ferrule connector to connect to the ark of the Lord; Deputy ark buy a dust explosion-proof electric cabinet, dust explosion-proof electric cabinet built-in main cases of positive pressure protection and control unit of power, and through the line connected with main tank, gas path export.

Explosion-proof fire ventilation cap with bolt connection with base, middle add sealing washer. Pressure relief valve installed in the main tank at the top of the hole. Flame retardant breathable cover cap base on the outside of the pressure relief valve, and full welding on the main tank top. Explosion-proof solenoid valve end by unicom card sleeve joint and copper pipe and the ark, the other end through the card sets of joints and brass with explosion-proof fire vent cap base thread interface connection. Adjustable one-way throttle valve end through the card sets of joints and copper pipe and the main tank unicom, on the other side through the card sets of joints and brass with explosion-proof fire vent cap base thread interface connection.
