Breather valve for IBC tank

Abstract

The invention belongs to the technical field of breather valves, and particularly relates to a breather valve for an IBC tank. The breather valve comprises a valve element, a breather pad and a dustproof cover. When the pressure of outside gas is greater than that of gas in the IBC tank, the outside gas can extrude an air inlet valve, the air inlet valve moves downwards to be opened, and the outside gas can enter a sliding groove formed in a first valve through the air inlet valve; the gas entering the sliding groove passes through a connecting hole and enters each connecting pipe; the gas entering the connecting pipes enters an annular groove formed in a connecting annular shell after being subjected to warming of heat preservation cotton, then the gas enters a heating groove formed in the IBC tank, is heated by a heat preservation layer wrapping on the outer side of the IBC tank in the heating groove, and finally, enters the IBC tank; and the temperature of the inlet gas is ensured.

Description

[0001] Technical field [0002] The invention belongs to the technical field of breathable valves, in particular to a breathable valve used for an IBC barrel. Background technique [0003] The IBC breather valve plays the role of adjusting the air pressure inside and outside the IBC barrel during use. When the pressure inside the IBC barrel exceeds the external pressure value, the vent valve opens to discharge a part of the gas in the IBC barrel into the atmosphere to reduce the pressure in the IBC barrel. Enter the IBC barrel, increase the pressure in the IBC barrel, and ensure the safety of the IBC barrel through air intake and exhaust. [0004] For the storage of IBC barrels containing urea, in winter, it is necessary to wrap an insulation layer around the barrel to prevent the interior from freezing, but because of the existence of the breathable valve; It is not easy to install and take off. Generally, for the IBC barrels containing urea, in order to facilitate the loa...

Problems solved by technology

[0004] For the storage of IBC barrels filled with urea, in winter, it is necessary to wrap the insulation layer around the barrel to prevent the inside from freezing, but because of the existence of the breathable valve; not easy to install

In order to facilitate the loading and unloading of urea in general, the IBC barrel lid will not be wrapped with insulation layer, which will lead to partial freezing of the urea area under the breather valve.
