A portion of the solenoid valve core component 2 is fixedly disposed with the valve seat 1, and the solenoid valve core component and the valve seat are fixedly connected by threads. The valve seat 1 also includes a first interface channel 101 and a second interface channel 102. The first interface channel 101 communicates with the first valve chamber 11, and the control valve 100 can control the opening and closing of the first interface channel 101 and the second interface channel 102.

[0023] The control valve 100 also includes a throttle valve core component 3, and the valve seat 1 also includes a second valve chamber 12. The throttle valve core component 3 is at least partially located in the second valve chamber 12, and a portion of the throttle valve core component 3 is fixedly disposed with the valve seat 1. The throttle valve core component and the valve seat are fixedly connected by threads.

[0024] The valve seat 1 also includes a first flow channel 103, which connects the first interface channel 101 and the second valve chamber 12. The second valve chamber 12 is connected to the second interface channel 102. The control valve 100 can control the cut-off and conduction of the first flow channel 103 and the second interface channel 102, or the control valve 100 can control the fluid flow rate of the second interface channel 102.

[0025] The valve seat 1 also includes a first valve port portion 1111, which protrudes from the bottom wall of the first valve cavity 11. The first valve port portion 1111 has a first valve port 110, which can connect to the first interface channel 101 and the second interface channel 102.

[0026] The first valve chamber 11 also includes a groove region 1112, which is located between the outer wall of the first valve port 1111 and the corresponding side wall of the first valve chamber 11. The bottom wall of the groove region 1112 is the bottom wall of the first valve chamber 11. The first interface channel 101 is connected to the groove region 1112, and the first flow channel 103 is connected to the groove region 1112, so that when the solenoid valve is closed, the first flow channel can be connected to the groove region.

[0027] The control valve 100 also has a second valve port 120, which is located in the throttle valve core component 3. The valve seat 1 also includes a second flow channel 104, which communicates with the second valve cavity 12. The second valve port 120 is located between the connection between the first flow channel 103 and the second valve cavity 12 and the connection between the second flow channel 104 and the second valve cavity 12.

[0028] The valve seat 1 also includes a first interface 13 and a second interface 14. The first interface 13 is located in the first interface channel 101, and the second interface 14 is located in the second interface channel 102.

[0029] The second interface channel 102 also includes a third flow channel 105 and a fourth flow channel 106. The third flow channel 105 can be connected to the first valve port 110, and the fourth flow channel 106 connects the third flow channel 105 and the second interface 14.

[0030] The first flow channel 103 includes a first sub-flow channel 1031 and a second sub-flow channel 1032. The first sub-flow channel 1031 is located in the first interface channel 101. The second sub-flow channel 1032 connects the first sub-flow channel 1031 and the second valve chamber 12. The second flow channel 104 is a part of the second interface channel 102.

[0031] The second port 14 is located on the periphery of the valve seat 1. The axis of the second port 14 is parallel to the axis of the fourth flow channel 106, which makes it easier for the refrigerant in the fourth flow channel 106 to flow out of the valve seat 1 from the second port 14, thereby relatively reducing the flow resistance of the control valve.

[0032] During operation, with the first valve port 110 open and the second valve port 120 closed, the refrigerant enters the first valve chamber 11 through the first interface channel 101, then enters the third flow channel 105 and the fourth flow channel 106, and finally flows out of the valve seat 1 from the second interface 14. With the first valve port 110 closed and the second valve port 120 open, the refrigerant enters the first flow channel 103 through the first interface channel 13, then enters the second valve chamber 12, and finally flows out of the valve seat 1 from the second interface 14.

[0033] The control valve has an integrated throttling valve core component on its seat, which can relatively reduce the number of connecting pipelines for the control valve.

[0034] Please refer to Figure 7 As shown, in another embodiment, the structure of the second interface channel is different from that in the first embodiment. The second interface 14' is located at the bottom of the valve seat 1' and directly below the second valve chamber 12, which makes it easier for the refrigerant in the second valve chamber 12 to flow out of the valve seat 1' from the second interface 14', thereby relatively reducing the flow resistance of the control valve.

[0035] Please refer to Figure 8 As shown, in the third embodiment, the second interface channel 102 further includes a third flow channel 105, which connects the first valve port 110 and the second interface 15. The second flow channel 104 connects the second valve chamber 12 and the second interface channel 102. The second interface 15 is located on the periphery of the valve seat 10, and the axis of the second interface 15 is parallel to the axis of the second flow channel 104, making it easier for the refrigerant in the second flow channel 104 to flow out of the valve seat 10 from the second interface 15, thereby relatively reducing the flow resistance of the control valve. The other parts of the structure are the same as in the first embodiment.

[0036] Please refer to Figure 9 As shown, in the fourth embodiment, the structure of other parts is the same as that of the third embodiment, but the second interface 15' is located at the bottom of the valve seat 10', and the axis of the second interface 15' is parallel to the axis of the third flow channel 105, so that the refrigerant in the third flow channel 105 can more easily flow out of the valve seat 10' from the second interface 15', which can relatively reduce the flow resistance of the control valve.

[0037] Please refer to Figure 10 As shown, in the fifth embodiment, the first flow channel 103' directly connects the first valve chamber 11 and the second valve chamber 12, which can relatively reduce the flow channel length and relatively reduce the flow resistance. The other parts are the same as the structure of the first embodiment.

[0038] Please refer to Figure 11 As shown, in the sixth embodiment, the first flow channel 103' directly connects the first valve chamber 11 and the second valve chamber 12, which can relatively reduce the flow channel length and relatively reduce the flow resistance.

[0039] Please refer to Figure 12 As shown, in the seventh embodiment, the first flow channel 103' directly connects the first valve chamber 11 and the second valve chamber 12, which can relatively reduce the flow channel length and relatively reduce the flow resistance. The other parts are the same as the structure of the third embodiment.

[0040] Please refer to Figure 13 As shown, in the eighth embodiment, the first flow channel 103' directly connects the first valve chamber 11 and the second valve chamber 12, which can relatively reduce the flow channel length and relatively reduce the flow resistance. The other parts are the same as the structure of the fourth embodiment.
