Open the breathing valve quickly

​The quick opening breathing valve is a gravity type structure with overlapping valve seats.
DETAILS:

The quick opening breathing valve is a gravity type structure with overlapping valve seats. It is characterized by soft contact with air cushion between valve disc and valve seat, good air tightness, not easy to frost and freeze, suitable for use in cold areas. The traditional breathing valve of storage tank is combined with the fire arrester of storage tank. The flame arrester is placed at the suction port of the breathing valve to prevent the fire source from entering the breathing valve shell. It has the characteristics of small volume, light weight, compact structure, large ventilation capacity and small leakage, and has good sealing performance. Especially when working at high altitude, it is very convenient to overhaul and clean the fire retardant disc and positive and negative pressure valve disc in the fire retardant breathing valve 。 It is installed on the top of the tank to solve the positive pressure and negative pressure gas in the tank, so that the liquid in and out of the tank is not obstructed. When the external liquid is input into the tank, a large amount of gas is called out (called positive pressure). If the liquid in the tank is exported to the outside, the air inside the tank is sucked into the tank from the outside (called negative pressure). If the breathing valve closes automatically when it stops working, the liquid and gas in the tank will not leak out.
