Abstract

The invention discloses an electromagnetic valve pulse test tool used for an oil pressure electromagnetic valve. The electromagnetic valve pulse test tool comprises a tool body, an oil feed pipe and an oil discharge pipe, wherein the tool body is provided with a tool oil inlet corresponding to an oil inlet of the oil pressure electromagnetic valve and a tool oil outlet corresponding to an oil outlet of the oil pressure electromagnetic valve, and the tool body is provided with an oil feed channel communicated with the tool oil inlet and an oil discharge channel communicated with the tool oil outlet; the oil feed pipe is communicated with the oil feed channel in a sealed mode; the oil discharge pipe is communicated with the oil discharge channel in a sealed mode. Through the electromagnetic valve pulse test tool, a pressure pulse test of the oil pressure electromagnetic valve is achieved in the mode that pressure oil is not directly fed into the oil pressure electromagnetic valve but pressure oil is fed into the tool body. Thus, through the electromagnetic valve pulse test tool, change-over of the oil inlet and the oil outlet of the oil pressure electromagnetic valve of a screw compressor is achieved, oil pressure pulse and voltage withstanding tests can be conducted on the electromagnetic valve, the reliability of the oil pressure electromagnetic valve is verified, and the hidden danger that the sold oil pressure electromagnetic valve leaks is avoided.

Description

technical field [0001] The invention relates to the technical field of tooling for air-conditioning units, and more specifically relates to a pulse test tooling for electromagnetic valves. Background technique [0002] Oil pressure solenoid valves used on screw compressors, such as figure 1 with figure 2 As shown, the oil inlet hole 102 and the oil outlet hole 103 of the oil pressure solenoid valve are two positions where the oil pressure solenoid valve circulates. 101 is used for fixing the solenoid valve, and is mainly locked by hexagon socket head bolts. The sealing surface of the oil pressure solenoid valve is a flange surface, which is sealed by a gasket, and the oil inlet hole 102 and the oil outlet hole 103 are distributed on the same plane. [0003] In order to verify the ability of the oil pressure solenoid valve to withstand impact pressure, there are currently standards that require a pressure pulse test for the oil pressure solenoid valve. Connect the oil pr...
