[0015] This embodiment provides a gas-liquid separator integrated stop valve structure, such as Figure 1-3 As shown, it includes a gas-liquid separator 1 and a stop valve 2 connected thereto, the gas-liquid separator is provided with a refrigeration inlet 3 and a heat pump heating inlet 4, the stop valve includes a valve body 5 and a driving coil 7 connected thereto through a fixing member 6, the valve body is provided with a receiving cavity 8 and a valve port 9 which are interconnected therewith; a stationary core iron 10 is installed in the receiving cavity; a moving core iron 11 is provided at one end of the stationary core iron close to the valve port, and the stationary core iron is drivingly connected to the moving core iron so that the moving core iron moves in the receiving cavity, a valve needle 12 is connected to one end of the moving core iron close to the valve port, and a piston 13 for blocking or opening the valve port is provided at one end of the valve needle close to the valve port;

[0016] A fixed connecting ring 14 is arranged on the outer side of the valve body, and a connecting thread is arranged on the fixed connecting ring. The stop valve is threadedly connected to the gas-liquid separator through the connecting thread. A rubber sealing ring 15 is arranged on the outer side of the valve body above the fixed connecting ring, and an annular groove is arranged on the outer side of the valve body at one end of the valve port. A rubber sealing ring 2 16 is arranged in the annular groove. A limiting plate 17 is arranged on the fixing part, and the limiting plate is clamped with the limiting groove 18 arranged on the gas-liquid separator.

[0017] In this embodiment, the stop valve is threadedly connected to the gas-liquid separator. After the driving coil is energized, the moving iron core is driven to move, and the moving iron core drives the valve needle to move, so that the piston opens or closes the valve port. In the summer cooling mode 5, the stop valve is closed, and the refrigerant enters the gas-liquid separator from the cooling port of the gas-liquid separator, and then comes out from the gas-liquid separator outlet to enter the compressor. When the heat pump is heated in winter, the stop valve is opened, and the refrigerant enters the gas-liquid separator from the heat pump heating inlet of the gas-liquid separator, and then comes out from the gas-liquid separator outlet to enter the compressor.

[0018] This embodiment has a simple structure and a small size. The stop valve is fixed to the gas-liquid separator by a threaded connection, which is convenient for disassembly and installation as well as subsequent maintenance. At the same time, the stop valve traditionally arranged on the pipeline is directly integrated into the gas-liquid separator, thereby improving the degree of integration. Rubber sealing ring 1 and rubber sealing ring 2 are respectively arranged on the valve body to play a sealing role and ensure that the refrigerant does not leak.

[0019] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
