Abstract

The anti-explosion breather valve for the oil tank comprises a shell, a first connecting pipe is fixedly installed on the side of the shell, a second connecting pipe is fixedly installed on the lower end face of the shell, and a first partition plate and a second partition plate are fixedly installed in the shell. According to the anti-explosion breather valve for the oil tank, the first partition plate and the second partition plate are arranged to separate the negative pressure cavity from the positive pressure cavity, when the negative pressure valve seat moves upwards, the first connecting hole and the second connecting hole in the upper portion are communicated, gas in the negative pressure cavity needs to enter the positive pressure cavity through the connecting holes, and when explosion occurs, fire spreading can be effectively reduced; when explosion occurs, flames firstly make contact with the first fireproof net, then enter the upper end of the first partition plate and then enter the lower end of the second partition plate through the connecting holes, the fire behavior is greatly reduced in the process, and finally the flames are blocked by the second fireproof net. And the explosion-proof performance of the breather valve is greatly improved.

Description

technical field [0001] The invention relates to the technical field of breathing valves, in particular to an explosion-proof breathing valve for oil tanks. Background technique [0002] Breathing valve refers to a valve that not only ensures that the storage tank space is isolated from the atmosphere within a certain pressure range, but also communicates with the atmosphere when it exceeds or falls below this pressure range. Its function is to prevent the storage tank from being damaged due to overpressure or vacuum. , while reducing the evaporation loss of the storage liquid. [0003] Nowadays, the internal structure of most breathing valves is relatively simple. The negative pressure chamber and the positive pressure chamber are connected together, and there is no buffer area. When an explosion occurs, the flame directly enters the positive pressure chamber through the negative pressure chamber, which cannot reduce the fire. spread. SUMMARY OF THE INVENTION [0004] Th...
