The invention provides a pre-pressing breather valve test board, relates to the technical field of test equipment, and solves the technical problems that breather valve test equipment is unstable in test, inaccurate in result and incomplete in test function. The pre-pressing breather valve test board comprises a rack, a plurality of test stations are arranged on the rack side by side, and each test station is provided with a positioning assembly used for fixing a breather valve; an expiration testing assembly, an inspiration testing assembly and pressure measuring assemblies are arranged in the rack, and the expiration testing assembly is connected with the breather valve of each testing station through a first pipeline so as to provide constant-pressure gas; the inspiration testing assembly is connected with the breather valve of each testing station through a second pipeline so as to provide negative pressure gas with set inspiration flow; and the pressure measuring assemblies are arranged on the first pipeline and the second pipeline so as to test the expiratory pressure and the inspiratory pressure. The pre-pressing breather valve test board is used for testing the expiration pressure and the inspiration pressure of the breather valve and has the advantages of being comprehensive in detection, high in accuracy, convenient to operate, time-saving and labor-saving.
Description
technical field [0001] The invention relates to the technical field of testing equipment, in particular to a pre-pressurized breathing valve test bench. Background technique [0002] Most of the domestic vehicle hydraulic systems use a pre-pressurized breathing valve installed on the fuel tank to adjust the pressure difference inside and outside the fuel tank to ensure a certain pressure in the fuel tank to prevent the pump from being sucked. When the oil in the fuel tank is too high and the pressure is too high The valve needs to be opened for exhaust, and when the oil pressure in the fuel tank is too low, the breathing valve is opened for suction to ensure a constant pressure in the fuel tank. [0003] In the prior art, in order to test whether the breathing valve can breathe in the set pressure range, the breathing valve is usually connected with an air compressor, and the air compressor is used to determine whether the breathing valve can be opened smoothly for exhalatio...
