The invention discloses an automatic checking and testing device for a breather valve. The automatic checking and testing device comprises a low-pressure gas storage tank, the breather valve to be checked and a computer at the operation end, wherein the low-pressure gas storage tank is communicated with the breather valve to be checked through a pipeline, a pipe of the pipeline is provided with a check valve, a vacuum pump, a pressure sensor and a vent valve, the vacuum pump, the pressure sensor and the vent valve are located on the portion, between the check valve and the breather valve to be checked, of the pipe, and the pressure sensor is electrically connected with the computer at the operation end through a data processor. The testing device further comprises a computer at the management end, wherein the computer at the management end is electrically connected with the computer at the operation end, and a server is arranged on a circuit between the computer at the management and the computer at the operation end. The automatic checking and testing device can accurately and automatically measure exhalation pressure and suction pressure of the breather valve, manage measurement data and results in a classified mode, and automatically generate detection reports and detection records, and detection operation is highly user-friendly.
Description
technical field [0001] The invention relates to an automatic calibration test device for a breathing valve. Background technique [0002] Breathing valve is a safety device installed on the roof of low-pressure storage tanks such as fixed storage tanks and transport storage tanks (storage of Class A and B liquids), used to keep the pressure of the storage tank at a normal state and reduce the volatility of the storage tank. The evaporative loss of the liquid protects the storage tank from possible damage caused by overpressure or ultra-vacuum. [0003] Breathing valve calibration refers to measuring the exhalation pressure and inhalation pressure of the breathing valve to be calibrated. If the measured result is not within the acceptable range, it needs to be adjusted and then re-tested until the measured exhalation pressure and inhalation pressure are within the range. within the qualified range. Therefore, the core of breathing valve calibration is to measure its exhalat...
