Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning valve body processing, in particular to a drilling processing device for an air-conditioning valve body. Background Art

[0002] The air conditioning stop valve is a valve used to control the flow of refrigerant in the air conditioning system. It is usually installed in the pipeline of the refrigeration system to open or close the flow of refrigerant. The working principle of the air conditioning stop valve is to control the cooling and heating functions of the air conditioner by changing the flow direction of the refrigerant. When the refrigerant flows in the stop valve, it controls the flow of the refrigerant through the valve port, thereby achieving the effect of cooling or heating.

[0003] In the prior art, when producing the air-conditioning stop valve body, it is necessary to use a drilling device to perform hole drilling operations on the air-conditioning stop valve body. During long-term use observation, it is found that when drilling holes in the air-conditioning stop valve body, the drilling device will generate a large torsional force when drilling, and the air-conditioning stop valve body may rotate together with the drilling device, thereby affecting the drilling effect and drilling efficiency of the air-conditioning stop valve body.

[0004] To this end, the utility model provides a drilling processing device for an air-conditioning valve body. Utility Model Content
