Integrated anti-overflow fire-retardant breather valve performance test system

Abstract

The invention discloses an integrated anti-overflow fire-retardant breather valve performance test system, a breather valve detection system comprises a temperature unit, an air pressure detection unit, a heating unit and a cooling unit, and the air pressure detection unit comprises a pressurizer, a connecting pipe, an air pressure sensor and a meson air pressure numerical value unit. The output end of the pressurizer is electrically connected with the output end of the air pressure sensor through a wire, and the output end of the air pressure sensor is electrically connected with the input end of the meson air pressure numerical value unit through a wire. The integrated anti-overflow fire-retardant breather valve performance test system solves the problems that existing detection is single, whether a fire arrester breather valve can be normally opened and closed or not under air pressure is detected, the use condition of the fire arrester breather valve on an oil tank cannot be simulated, and whether influences can occur or not under different temperatures, so that the fire arrester breather valve cannot be normally opened or closed or not. And in addition, the flame arrester can prevent backfire.

Description

technical field [0001] The invention relates to the technical field of breathing valves, in particular to an integrated anti-overflow and fire-resisting breathing valve performance testing system. Background technique [0002] The flame arrester breathing valve refers to the breathing valve and the flame arrester. The breathing valve and the flame arrester are used together, or they can be used separately. The breathing valve is an important accessory to protect the safety of the oil tank. It is installed on the top plate of the oil tank and is controlled by pressure. Valve and vacuum valve are composed of two parts. Its function is to maintain the airtightness of the oil tank and reduce the evaporation loss of oil to a certain extent. When necessary, it can automatically ventilate and adjust the internal and external pressure of the oil tank, which plays a safe role in the oil tank. When the oil and gas pressure in the tank is greater than the allowable pressure of the oi...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an integrated anti-overflow and flame arresting breathing valve performance test system, which solves the problem that the existing detection is relatively simple, and only detects whether the flame arrester breathing valve can be opened normally and whether it is under air pressure. Closed, it is impossible to simulate the use of the flame arrester breathing valve on the oil tank, and whether it will be affected at different temperatures, and whether the flame arrester can prevent backfire
