Gas jet valve detection device and method based on current detection

Abstract

The invention relates to the technical field of jet valve detection and particularly discloses, according to an embodiment, a gas jet valve detection device and method based on current detection. Thegas jet valve detection device comprises a gas jet valve driving module, a gas jet valve current acquisition module and a controller module; the gas jet valve driving module and the gas jet valve current acquisition module are separately connected with a gas jet valve; the controller module is connected with the gas jet valve current acquisition module. The gas jet valve detection device and method have the advantages that a current detection method used herein is to directly detect characteristics of a gas jet valve itself, the accuracy is high, conformity is good, the basic properties of thegas jet valve can be better revealed, the test structure is simple, and normal running of an external drive gas jet valve is just required; the method to reflect gas jet valve characteristics throughcurrent changes allows a uniform experiment standard to be established among the manufacturers more conveniently and is easier to accept by users.

Description

technical field [0001] The invention relates to the technical field of injection valve detection, in particular to a gas injection valve detection device and detection method based on current detection. Background technique [0002] As a reliable actuator that can control the flow of gas, the gas solenoid valve is widely used in industrial production, automotive engine systems and aerospace propulsion systems. Usually the gas injection valve technical indicators we pay attention to include the gas injection valve opening time and the gas injection valve closing time, which are the two core performance indicators of the gas injection valve, which directly reflect the performance of the gas injection valve. [0003] At present, the air pressure method is generally used for the performance test of the opening time of the gas injection valve and the closing time of the gas injection valve. The response time of the gas injection valve is reflected by collecting the pressure chan...

Problems solved by technology

However, this is an indirect test method. In the absence of unified and clear experimental test standards for major manufacturers, it is difficult for the test results to be authoritative and reliable.

And the air pressure method is used to test the technical indicators of the gas injection valve. The structure is relatively complicated, the pipeline needs to provide a certain value of air pressure, and a specially designed air pressure change collection chamber is required at the rear end, which brings certain limitations and complexity to the test. sex
