Liquid-drip-proof liquid-sealed breathing valve

Abstract

The utility model discloses a kind of liquid-droplet-spraying-preventing liquid seal breathing valve, it is related to breathing valve technical field.The liquid seal breathing valve includes valve seat and rain cover, the outer wall of the valve seat is provided with liquid collecting groove, sealing liquid is placed in the liquid collecting groove.The outer wall of the valve seat is fixed with first anti-splashing baffle, the inner wall of the liquid collecting groove is fixed with second anti-splashing baffle.The rain cover is covered in the liquid collecting groove outer, and with the liquid collecting groove fixed connection;The rain cover is provided with separation cylinder, and the separation cylinder is located between the first anti-splashing baffle and the second anti-splashing baffle.In the utility model, separation cylinder cooperates with first anti-splashing baffle and second anti-splashing baffle respectively, can effectively limit the liquid level fluctuation of sealing liquid, avoid sealing liquid splashing out liquid storage tank to pollute surrounding environment and cause liquid pollution problem to storage tank inner.
