Abstract

The invention discloses a positive and negative pressure protector. The protector concretely comprises a gas inlet tube, a triplet, a negative pressure valve, a gas guide tube, an outer cylinder, a diffusion tube, a liquidometer and an overflow tube. The length of the overflow tube is adjusted to change the liquid seal height, so the positive pressure of a container is adjusted; and the triplet is adjusted and the angle of the negative valve is changed to adjust the negative pressure of the container, so the positive and negative pressures in the container are conveniently adjusted, thereby the suck-shriveling and expansion-cracking of the container are effectively prevented.

Description

technical field [0001] The invention relates to the protection field of storage gas containers, in particular to a positive and negative pressure protector. Background technique [0002] When the gas produced by fermentation is stored in inflatable equipment such as membrane gas cabinets and steel tanks, other changes in the tank will occur due to changes in the container itself or the external environment, causing potential safety hazards. Since the tank has a certain pressure range for the gas in the tank, if the pressure of the gas in the tank is lower than the rated pressure, you need to inhale a certain amount of air to ensure that the pressure of your gas is within the rated range; if the gas in the tank If the pressure is higher than the rated pressure, a certain amount of gas needs to be removed to achieve the purpose of protecting the tank. Therefore, it is necessary to install a positive pressure protector and a negative pressure protector to protect the container...
