The main valve and control valve four capillary connection four-way reversing valve, and the three root capillary connection compared the four-way reversing valve, control valve below three capillary connection in the same way, but on the control valve to increase the capillary connection to the main valve of wholesalemotor.blogspot.com high-pressure air inlet pipe 4, a high voltage channel. The four-way reversing valve control valve and main valve on the structure and movement theory, namely: the control valve is itself a four-way change valve. When the system is in a state of refrigeration, the electromagnetic coil is not electricity, release valve, valve core due to spring force moved to the left, capillary E and C, B and D, the main valve nozzle within 4 high pressure through capillary B and D into the right space inside the main valve, main valve in the space of the left by capillary C and E to the low pressure air gate 2, the main valve internal pressure is generator set spare parts right high left low, piston driven slider move to the left side, nozzle with the 1 in 2 and 4 with 3 connected; When the system is in a state of heating, electromagnetic coil current and the effect of electromagnetic force control valve valve core to move to the right end, capillary E connected with D, B and C, the main valve in the left side become high pressure and right side into a low pressure, the valve core is to the right side, the connecting tube 2 and 3, 4 and 1.

Expansion valve is an important component of the refrigeration system, general installation between the liquid storage container and evaporator. Expansion valve makes the temperature in the high 3 phase induction motor pressure liquid refrigerant through the throttle into low temperature low pressure wet steam, then the refrigerant in the evaporator absorbs heat cooling effect, expansion valve by the end of the evaporator superheat changes flow control valve, preventing evaporator area of under- utilization and knocking phenomenon of electronic expansion valve is according to the preset program conditioning evaporator for fluid volume, belongs to the electronic control mode, so called electronic expansion valve. It adapt to the development of the refrigeration and electromechanical integration requirements, has the good characteristics of thermal expansion valve can't compare with, provides conditions for intelligent control of cooling system, is a very promising control energy- saving components. The primary use of electronic expansion valve thermal expansion valve and the same, variety structure, but on the performance, there are many differences between this two.
