Embodiment 1

[0029] A communication valve structure for a pressure switch, including an exhaust valve 21 and a main body valve 22, the main body valve 22 is provided with an exhaust valve 21, the main body valve 22 connects the pressure switch 1 and the equipment pipeline, and the main body valve 22 is used to cut off the pressure switch 1 And the equipment pipeline, when the main body valve 22 is in the cut-off state, adjusting the exhaust valve 21 can make the refrigerant on the side of the pressure switch 1 of the main valve 22 be discharged through the exhaust valve 21;

[0030] One end of the main valve 22 is connected to the pressure switch 1 through the straight pipe 3, and the other end is connected to the equipment pipeline through the L-shaped pipe 4. The two ends of the main valve 22 are flared, and the straight pipe 3 and the L-shaped pipe 4 are respectively inserted into the main valve. One end corresponding to 22 is connected to the main valve 22 by brazing, and the connection...

Abstract

The invention provides a communication valve structure for a pressure switch, a pressure switch assembly and an air conditioner, relates to the technical field of pressure switches, and solves the technical problem of relatively large refrigerant discharge amount in the prior art when the pressure switch assembly of the air conditioner is replaced. The communication valve structure for the pressure switch is connected with the pressure switch and an equipment pipeline, wherein a pressure switch removal part is formed between the communication valve structure and the pressure switch, and when the communication valve structure intercepts the pressure switch and the equipment pipeline, refrigerant on the pressure switch side of the communication valve structure can be discharged by adjustingthe communication valve structure. The communication valve structure for the pressure switch provided by the invention facilitates the replacement of the pressure switch in an air conditioning fluorine system.

Description

technical field [0001] The invention relates to the technical field of pressure switches, in particular to a communication valve structure for a pressure switch, a pressure switch assembly including the communication valve structure and an air conditioner. Background technique [0002] At present, the pressure switch of the general air-conditioning fluorine system adopts a mechanical type, which can be found in figure 1 , The pressure switch is connected with the L-shaped copper tube to form an assembly, and then the L-shaped copper tube is brazed with the large tube. When the pressure switch fails and needs to be replaced, it is necessary to remove the refrigerant in the fluorine system, weld it off from the connection between the L-shaped copper tube and the large tube, and then re-weld the new pressure switch assembly; Inject refrigerant, debug and start up. For a system with a large cooling capacity, it will result in higher maintenance costs, longer maintenance interv...
