The working principle of four-way reversing valve

When electric motor price the electromagnetic valve is not electricity,work on the refrigeration system and the role of control valves for spring 1,valve core moves to the left side,is in a state of release,capillary E and C connected at this time. www.facebook.com/guohong.trading Because E on the low pressure suction tube,capillary C and main valve inside the left space for the low pressure,high pressure gas nozzle enters the main valve by the main valve,the main valve piston I vent in the right end of the space to become a high pressure,promote the main valve valve core is moved to the left,nozzle and nozzle 1 2 connecting the nozzle with the nozzle 3 in 4 and status form the refrigeration cycle system When the solenoid valve electricity,electromagnetic force pull-up control valve valve core to the right,capillary E connected to D. ac motor The main valve in the right space become low voltage,high pressure gas is entered into the main valve piston lamination II vent in the left space,promote the valve core to move to the right end,nozzle and nozzle 3 2 connecting the nozzle with the nozzle 1 in 4 and the function of the evaporator,condenser,exchange,system is transformed into heating circulation state.
