Background
One of the main safety accidents of oil storage tanks during road transportation of hazardous liquid media (such as oil products) is the explosion accident caused by overpressure or vacuum damage. GB18564.1 specifies that tanks for the shipment of flammable and explosive media should be provided with breather valves which should not leak in the event of a tank car tipping accident. The breather valve for oil tank truck is one of the necessary measures to reduce the oil gas discharge and ensure the use safety of oil storage tank when the inflammable medium (oil product) is transported by road. It is usually installed on top of the oil storage tank to avoid overpressure and negative pressure (vacuum) damage of the oil storage tank while reducing the amount of oil and gas loss. The action principle is as follows: under normal conditions, the breather valve is in a sealing state, so that oil (oil gas) is prevented from escaping, and the oil loss is reduced; when the pressure in the tank exceeds the environmental pressure, the breather valve opens to exhale outwards, so that the overpressure expansion deformation damage of the oil storage tank is avoided; when the pressure in the tank is lower than the environmental pressure (namely when negative pressure appears in the tank), the breather valve opens to suck air into the tank, and the negative pressure of the oil storage tank is prevented from being compressed, deformed and damaged.

At present, the existing breather valve inspection device for the tank truck has the defects of insufficient functions, single specification of a tested product, low automation degree, low measurement precision, complex and irregular detection process (a plurality of devices are required to be spliced at multiple stations in a test, for example, 2 sets of devices are required for built-in and external breather valves), high cost and low efficiency, cannot meet the measurement requirements of functional items such as the opening pressure (positive pressure and negative pressure), the valve seat tightness, the overturning tightness and the like of the breather valve for the tank truck specified by QC/T1064 and BS EN 14595, can only qualitatively measure the leakage amount, cannot realize accurate measurement, and is not beneficial to the improvement and wide application of product quality.
