The problems in the process of the localization of electromagnetic valve

Solenoid valves in the process of localization of li problems in the network times, flexible control valve action not only control valve switch freely, sensitive and reliable, and can effectively control pollution the main valve opened or closed, to achieve timing drainage, guarantee the normal work of the compressor. At the early stage of the localization of the valve in use process, sometimes appear on the solenoid valve, closing seal is lax. Found after overhaul of valve core guide bar rusting, can not freely slide in the core, this is because the sewage with oil, such as water to remove dirt with gas into the clearance between guide rod and the core, guide rod causes corrosion. To improve the control valve parts structure ( See the figure) , at the bottom of the core O ring, make sure no oil, water and other dirt into the clearance between guide rod and the core. So as to achieve the control valve core freely slide in the core, to ensure the reliable air compressor discharge. Second, the rectifier diode is punctured the solenoid valve for dc electromagnetic valve, V ac input, by a bridge rectifier circuit into V dc effect on power about W dc coil. After electrify coil to generate electromagnetic force used on the core core drives the valve core to realize seating, electromagnetic valve is closed. Solenoid valve, losing electricity coil on the instantaneous release will produce a high peak power to reverse voltage, the voltage effect to likely breakdown diode rectifier diode. To choose high voltage of diode bridge rectifier circuit are improved, and the bridge circuit and load in parallel bidirectional diode, used to release the above in order to protect the peak reverse voltage rectifier diode. Well solve the problem of the rectifier diode is punctured. Solenoid valve solenoid valve factory hours telephone landline fax order
