Use:
A one-way valve is an important part of air conditioning system,and the capillary with refrigerant is,to reverse direction flow control function.
Characteristic:
Using high quality engineering plastic,stainless steel valve core manufacturing, reliable performance.
Operational Principle:
（1）when the fluid from flowing,core to refrigerant flow pressure itself is open to, the retaining ring(or pin),the one-way valve is turned on;when the refrigerant from the entry,spool due to weight and the one-way valve at both ends of the pressure difference,pressed forming on the seat seal.
（2）the one-way valve and pipe parallel the structure forms,in the refrigeration cycle,the refrigerant flowing through the one-way valve positive; in the heating cycle,the refrigerant flow in the opposite direction,the one-way valve sealing,refrigerant through a heating capillary,This can make the air conditioner in the cooling and heating conditions,by changing the length of capillary flow obtained different so that the air conditioner is running properly.
