Zusammenfassung: | The invention provides a pilot (control) valve of an air conditioner four-way reversing valve, and relates to the appearance, structure and machining technology of the pilot (control) valve, in particular to the technical field of machining technologies of pilot valve bodies of air conditioner four-way reversing valves. A valve body of the pilot (control) valve of the air conditioner four-way reversing valve is made of a stainless steel material or an aluminum alloy material, machining is easy, the technologies such as spinning or upsetting reducing and stamping are used, integrated and process machining forming is achieved, the assembling position of a capillary seat is limited through a positioning tool, and integrated welding of a structure of the air conditioner four-way reversing valve is facilitated. A poisoning bulged point is designed on an end cover of the valve body of the pilot (control) valve of the air conditioner four-way reversing valve and used for fixing and embeddingof the pilot (control) va |
