    EVR20 Refrigeration Solenoid Valves are connected to a series of refrigerating system ducts and are controlled by a command signal from a pressure relay, relay, temperature level controller and manual switch to open and close system fluid ducts, and are commonly used for refrigeration. System pipes open and close automatically with system control commands. When connected to the controller, it can cut off the flow of fluid in the system.

    Function of EVR20 refrigeration solenoid valve in refrigeration system:

    EVR20 Refrigeration Solenoid Valve can be used in evaporator liquid supply lines. When the compressor is shut down, the liquid can be closed into the evaporator to prevent the wet steam from entering the evaporator when the compressor is shut down. The compressor produces the liquid hammer. Another example is the cooling water pipe used by the condenser, which automatically cuts off or opens the water source while the compressor is turned on and off to save cooling water. In addition, the solenoid valve can also be used as a pilot valve to control the main valve and other applications. In short, it is combined with some automatic electrical appliances, constitute the refrigeration system automatic control and regulation of the main components.

     

    Cold storage EVR refrigeration solenoid valve selection, installation and inspection considerations:

    The working current, voltage, frequency and power of each solenoid coil have a certain range, which cannot be abused to avoid burning out. As the voltage drops, so does the coil's suction. When the ac frequency is low, the suction increases, but the coil is hot, easy to burn out. When assembling the solenoid valve, the coil part should be assembled correctly according to the drawings in the manual to avoid increasing the magnetoresistor. The increase of magnetoresistance will not only reduce the electromagnetic suction, but sometimes the direction of the suction is not correct, affecting the valve action.


    Different duty stations should use different types of electromagnetic widths. For example, solenoid valves in refrigerant lines should not be used in water pipes because water can scale, solid impurities are difficult to avoid and can easily clog small balance holes in the diaphragm. For the solenoid valve on the oil separator return pipe, shockproof measures should be taken to avoid the compressor exhaust pressure fluctuation to open and close the auxiliary valve. For use with suction solenoid valves, use hygroscopic coils or close solenoid valves as they are prone to condensation. Should be used when the environment temperature is higher than 40 ℃, hot coil, etc.


    Solenoid valve must coil, vertical installation in the pipeline, otherwise, because the core can not work properly and failure. Solenoid valve media flow from the top of the spool to the bottom, so must be in accordance with the direction of the arrow marked on the valve body installation, arrow direction for the flow of pipeline media.


    In order to check whether the solenoid valve works normally, a light bulb can be connected in parallel on the power line of the solenoid valve to indicate its switching state. Manual switch is also available in series on the power line of the solenoid valve. When the circuit and manual switch on and off, if you can hear the sound of the solenoid valve spool action, the solenoid valve is working normally. The abnormal operation of solenoid valve mainly occurs in three aspects: coil burning, spool sticking and iron core remanence. The core can be removed and removed by heating or tapping if the core residues do not allow the power to drop automatically.
