Problems solved by technology

[0003] Since there is currently no relevant detection device that can reliably detect parameters such as the life of the valve spring in the refrigerant filter, it is urgent to design and develop a detection device for the check valve assembly in the refrigerant filter. Detect and evaluate parameters such as the service life of the valve plate spring to improve its filtering effect and service life on refrigerant

Abstract

The invention relates to a detection device and method of a valve block spring of a refrigerant filter. The detection device of the valve block spring of the refrigerant filter comprises a pressure pulse device and a detecting element, the pressure pulse device enables detection media to be arranged in the refrigerant filter to be detected in a filling mode or discharged out of the refrigerant filter to be detected through a connecting pipeline, so that opening and closing of a one-way valve assembly including the valve block spring in the refrigerant filter to be detected are achieved, and the detecting element is used for obtaining parameters related to the reliability of the valve block spring. According to the detection device and method, the detection media are arranged in the refrigerant filter in a reciprocating and filling mode through the pressure pulse device, ceaseless opening and closing of the one-way valve assembly including the valve block spring in the refrigerant filter are achieved, and through motion simulation similar to the actual use process, detection and evaluation of the parameters, such as the service life of the valve block spring, related to reliability are achieved.

Description

technical field [0001] The invention relates to a spring detection device and method, in particular to a detection device and method for detecting parameters related to the reliability of the valve spring, such as the service life of a valve spring of a one-way valve assembly in a refrigerant filter. Background technique [0002] During the connection process of the refrigerant, the pipeline and other gas impurities will cause pollution to it. Therefore, a refrigerant filter is used in the entropy inspection room to filter the refrigerant entering the system to improve the purity of the refrigerant. In the refrigerant filter structure, the one-way valve assembly directly determines the filtering effect and the service life of the refrigerant filter. The working principle of the refrigerant filter is mainly to push the refrigerant into the filter element through pressure. After filtering through the filter element, the pressure of the refrigerant will open the one-way valve a...
