One-way valve industry solutionsAs a key component of the flow path control of the refrigeration system, the air-conditioning check valve's sealing performance directly affects the system energy efficiency and operational stability. Under the harsh working conditions of high pressure and high frequency opening and closing, the sealing failure of the one-way valve will lead to refrigerant backflow and system pressure imbalance, seriously affecting the refrigerationeffect. Hairis provides professional sealing testing solutions for the special structure and working principle of air conditioning check valves to ensure that the product maintains excellent sealing performance throughout its life cycle.
We provide precise testing for the three key sealing parts of air conditioning check valves:
Valve core and valve seat sealing surface inspection
Evaluate the sealing performance of the mating surface of the valve core and valve seat to ensure zero leakage sealing effect when the pressure is reversed.
Welding part seal verification
Conduct precise inspections on the welding parts of the valve body and the nozzle to prevent refrigerant from leaking from the welds.
Seal component performance evaluation
Detect the compression permanent deformation characteristics of the sealing ring in the valve to verify its sealing durability in long-term use.
Quality and reliability
The detection accuracy is as high as 99.98%, ensuring system stability
Achieve 100% online inspection of products and reduce the leakage defect rate to less than 0.002%
Effectiveness and Efficiency
Detection efficiency increased by 6 times, single piece detection ≤5 seconds
Quality costs are reduced by 40%, and repair rates are reduced by 85%
