IBC barrel breather valve

Abstract

The invention belongs to the technical field of breather valves, and particularly relates to an IBC barrel breather valve which comprises a valve element, a breather pad and a dustproof cover. When air is exhausted in an IBC barrel, an annular valve shell and a first valve can be locked firstly, namely, the upper end of the annular valve shell is blocked, and the lower end of the annular valve shell is opened; at the moment, air in the IBC barrel is exhausted into the annular valve shell, and gas in the annular valve shell cannot be intersected with external gas, so that convection and radiation heat loss are basically avoided. Then, a second valve is closed, the first valve is opened and the second valve is closed and locked at the same time, namely, the lower end of the annular valve shell is blocked, the upper end of the annular valve shell is opened, at the moment, gas in the annular valve shell is exhausted to the outside through the first valve, and in the state, the second valveblocks the lower end of the annular valve shell, so that the heat of the gas in the IBC barrel is basically not greatly lost, and the heat of the gas in the IBC barrel is prevented from being greatlylost in the exhaust process of the gas.

Description

[0001] Technical field [0002] The invention belongs to the technical field of breathable valves, in particular to an IBC barrel breathable valve. 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.

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.
