Description

TECHNICAL FIELD

[0001] The utility model relates to air conditioner related part technical field, concretely is a light -duty pipe clamp. BACKGROUND

[0002] In the cooling and heating type air conditioning system, the air conditioner is through the heat transfer to the outdoor to realize when refrigerating, and the refrigerant absorbs heat and vaporizes in the indoor unit, then releases heat and liquefies in the outdoor unit, thereby reducing indoor temperature. When air conditioner heating, the heat is transferred to the indoor from the outdoor. The refrigerant absorbs heat and vaporizes in the outdoor unit, then releases heat and liquefies in the indoor unit, thereby improving indoor temperature. In the refrigeration and heating mode, the function of evaporator and condenser will be exchanged. When refrigerating, the indoor unit is evaporator, and the outdoor unit is condenser; when heating, the indoor unit is condenser, and the outdoor unit is evaporator. The exchange of indoor unit and outdoor unit function is realized through electromagnetic four-way reversing valve. Therefore, electromagnetic four-way reversing valve is an essential part in air conditioning system. Because the volume of electromagnetic four-way reversing valve is large, and it is welded with various pipelines of air conditioning system, so it needs to be fixed well to prevent cracking of welding joint and leakage of refrigerant due to vibration.

[0003] The traditional fixing method is to use the light -duty pipe clamp used in industry for fixing, but because the structure of electromagnetic four-way reversing valve is special, there is a 3mm pressure pipe on the outside of the pipe body to push the valve core of electromagnetic four-way reversing valve to slide and change the flow direction of refrigerant. Therefore, when fixing the electromagnetic four-way reversing valve, a groove is needed to be opened on the light -duty pipe clamp to avoid the 3mm pressure pipe, so as to prevent the light -duty pipe clamp from extruding the 3mm pressure pipe and causing its internal blockage, resulting in failure of electromagnetic four-way reversing valve. Therefore, workers need to process a groove on each light -duty pipe clamp during installation each time. Because it is manual operation, it not only increases the workload of workers, but also is difficult to ensure that the opened groove meets the technical process requirements, and it is also not beautiful. If the 3mm pressure pipe is damaged, the four-way reversing valve can only be replaced, which is a large amount of work; and it also leads to the waste of previous welding and pressure maintaining work.
