Abstract

The invention discloses a method for testing the opening degree of a breather valve. A mechanical part and a circuit acquisition part are included, the two parts are connected and matched with each other and are correspondingly arranged and operated; a displacement signal of the breather valve clack is converted into an electric signal; therefore, high-speed online real-time monitoring and acquisition of the opening degree of the breather valve under multiple working conditions and multiple mechanisms are realized; in the working process of the breather valve, by detecting the opening degree of the breather valve in real time and recording the flow in the working process of the breather valve, the gas release rate can be calculated, and therefore the gas release process can be further simulated.

Description

technical field [0001] The invention relates to the field of breathing valve experimental devices, in particular to a method for testing the opening of a breathing valve. Background technique [0002] The breathing valve is an indispensable safety device installed on the transport storage tank and used to fix the storage tank. It is mainly used to ventilate the storage tank and the outside world, maintain the balance of the air pressure in the storage tank, and prevent the tank from being damaged by overpressure or vacuum. Destruction, so as to avoid major combustion and explosion accidents. At present, there are not many detection devices for the opening of the breathing valve. Most people only consider the test of the opening pressure of the breathing valve and the flow of the breathing valve, and ignore the test of the opening of the breathing valve. During the discharge process of the breathing valve, the discharge flow rate of the gas can be measured by the flow meter,...
