Solenoid valve is how to work it?
    The utility model relates to an electromagnetic valve, which is a switch type (double position type) automatic valve, which is suitable for various refrigerants, including gas and liquid refrigerant, fresh water, salt water and lubricating oil. It is a component that must be equipped in the screw type refrigerator, which is usually installed between the liquid storage device (or condenser) and the expansion valve.
    Although there are many forms of solenoid valve, but according to its action principle, basically divided into two:
    1, direct action, that is a single open;
    2, indirect action, namely the two open type. In the screw chiller, solenoid valve coil field is often connected with the circuit of a motor compressor when the compressor is running, open, the solenoid valve opens; when the compressor closed operation, solenoid valve closes immediately, to avoid a large number of liquid refrigerant into the evaporator in the machine, when the compressor starts again to prevent the occurrence of the phenomenon of liquid hammer cylinder.
    Solenoid valve working principle is: when the power is turned on, the coils generate a magnetic field, the heart of iron magnetic suction, the valve port is opened, the inflow end and discharge end is communicated; when the coil power supply is cut off, the magnetic force disappears, the spring force and the iron heart closed under the action of dead weight valve.
    On the selection of solenoid valve, generally based on the size of the pipe size matching, in addition to the use of the screw for the medium of the valve body material. East Star screw refrigerator solenoid valve are selected well-known brands, 100% new original.
