As preferably, adopt argon arc welding or laser beam welding to be welded to connect between the 234 adapter and the valve seat mouth.
As preferably, valve seat and square connection mouth adopt argon arc welding or laser beam welding to be welded to connect.
As preferably, first takes over and is processed by the red copper material, adopts soldering to be welded to connect with the circular connection mouth of main valve body.
As preferably, first takes over and is processed by stainless steel material, adopts argon arc welding or laser beam welding to be welded to connect with the circular connection mouth of main valve body.
As preferably, the centre of said valve seat is plane, two ends bending, and section is ' [' type shape.
As preferably, the material of the valve seat that said punching press is processed is copper coin or corrosion resistant plate.
Beneficial effect of the present invention: the present invention is through changing material and the group technology and the structure of valve body, valve seat, adapter; Cost of material descends; The technology cost descends, the scolder cost descends; Also help reducing the radiation loss of four-way change-over valve, thereby improve the efficiency of air-conditioning system at heat pump type air conditioning system.
Characteristic of the present invention and advantage will combine accompanying drawing to be elaborated through embodiment.
