Abstract

The invention discloses an electromagnetic valve air tightness test device. The electromagnetic valve air tightness test device comprises a first cylinder, a first piston rod, a support, an electromagnetic valve fixing seat, a second cylinder, a connection rod, a ventilation sleeve, a second piston rod, a buffer head, an air inlet pipe, an oil tank and oil, wherein the first cylinder is fixed above the oil tank, the first piston rod stretches out from a lower side of the first cylinder, a lower end of the first piston rod is fixedly connected with the support, the support is provided with a transverse through hole, a right end of the support is fixedly provided with the electromagnetic valve fixing seat at the transverse through hole, a left end of the support is fixedly connected with thesecond cylinder through the connection rod, the second piston rod of the second cylinder stretches out rightwards and extends into the transverse through hole, and the second piston rod is internallyprovided with a center hole opened at a right end. The electromagnetic valve air tightness test device is advantaged in that the compressed air and the oil are employed to test air tightness of an electromagnetic valve, and compact structure, low cost, reliable action and high test efficiency are further realized.

Description

technical field [0001] The invention relates to an airtight test device, in particular to a solenoid valve airtight test device. Background technique [0002] The solenoid valve used on the high-pressure oil pump is one of the key components of the high-pressure common rail system. If the solenoid valve leaks oil during the operation of the high-pressure common rail system, it will seriously affect the working performance of the entire system, and then affect To the stability and reliability of the oil supply, therefore, in the manufacturing process of the solenoid valve, how to check the solenoid valve with leakage is an urgent problem to be solved. Contents of the invention [0003] The object of the present invention is to provide a solenoid valve airtightness test device, which is used for the solenoid valve airtightness test, has the advantages of sensitive action and high test efficiency, and solves the problem of detecting a leaking solenoid valve through the test. ...
