According to the invention, the expansion valve body is inserted into the L-shaped mounting plate; the expansion valve body is clamped and fixed through the clamping mechanism, and the expansion valve body is connected with a fixed pipe through a joint mechanism, so that the expansion valve body is connected in a refrigeration system, and the expansion valve body is detected, so that the efficiency of installing the expansion valve body by people is improved, and the detection efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of expansion valve performance detection, in particular to an expansion valve performance automatic detection device and a process thereof. Background technique [0002] The expansion valve is an important part in the refrigeration system, generally installed between the liquid storage cylinder and the evaporator. The expansion valve makes the medium-temperature and high-pressure liquid refrigerant become low-temperature and low-pressure wet steam through its throttling, and then the refrigerant absorbs heat in the evaporator to achieve the cooling effect. The expansion valve controls the flow rate of the valve through the change of the superheat at the end of the evaporator to prevent Insufficient utilization of the evaporator area and cylinder knocking phenomenon. After the expansion valve is produced, the performance of the expansion valve needs to be tested. Generally, the performance is tested by connec...

The expansion valve makes the medium-temperature and high-pressure liquid refrigerant become low-temperature and low-pressure wet steam through its throttling, and then the refrigerant absorbs heat in the evaporator to achieve the cooling effect. The expansion valve controls the flow rate of the valve through the change of the superheat at the end of the evaporator to prevent Insufficient utilization of the evaporator area and cylinder knocking phenomenon. After the expansion valve is produced, the performance of the expansion valve needs to be tested. Generally, the performance is tested by connecting the expansion valve to the refrigerant pipe of the refrigeration system and detecting the refrigerant throughput at different temperatures. , but most of the existing detection equipment for expansion valves are installed manually, and the work efficiency is low. Therefore, we propose an automatic detection equipment for expansion valve performance and its process
