      How does the three-piece all-inclusive ball valve work? What is the working principle of the three-piece all-inclusive ball valve?

     1. When the flow direction of the refrigerant in the pipeline is consistent with the throttling direction of the high temperature check valve, push the limit ring in the valve to open the check valve and the valve is turned on, so that the refrigerant can flow.

     2. When the flow direction of the refrigerant is inconsistent with the throttling direction of the high temperature check valve, the check valve is in a blocking state at this time, the valve needle does not move, and the refrigerant cannot flow through the valve.

     3. In the entire air-conditioning pneumatic system, the one-way valve is opened during cooling, and the refrigerant smoothly passes through the one-way valve and the main capillary to play a cooling role. When heating, the one-way valve is closed and the refrigerant cannot pass through the one-way valve, but can only be heated through the auxiliary capillary network.
