Use and maintenance:
1、Recommended to assign specific units responsible for the use and maintenance
2、1-2 annual meeting of the regular maintenance solenoid valve is reliable and the best way to longevity. Electromagnetic valve within the following four types of solenoid valve is impeding normal work and shorten the life of reasons.
⑴、Media use changes
⑵、Rust inside receiver
⑶、Air compressor oil oxidized to produce carbon tar and other debris, mixed with pipeline
2.4Pipelines are dirt and other impurities in dust
3、Solenoid valve installed or again after a long time out to be put into operation leads to several media test action after normal work before the official
4、Valve steam again after a long time out and put into operation, should be discharged after examination condensed water moves several times, After normal working order and put into operation.
5、In the maintenance, the need to cut off power supply, shed medium pressure.
6、Coil not disassemble components
7、Disassemble for cleaning the solenoid valve may be used when kerosene `TCE, and other solutions. It should be noted, however rubber pieces may Swelling, Therefore it should change.
8、Unpick cleansing, according to the order of the components installed in restitution.
9、I have Fragile pieces of the company, when needed by the market, brochures explain.
10、Demolition order, fragile pieces, and other matters are not available between, to the headquarters of the Department of Technical Advisory（Advisory Hotline：0577-65021168）
□ Installation notes:
1．Installation should carefully read the product's instruction manual to check whether or not the products fully comply with the requirement, the installation of familiar elements, make preparations.
2．Installed solenoid valve coils upward, and maintain the vertical position, the solenoid valve on the arrow or marking should be consistent with the pipeline flow, not installed in a splash of water or leaks place.
3．Before taking over with the pressure of 0.3MPa full irrigation channels, pipelines metal powder residue sealing material, Rust remove dirt, etc.; Solenoid Valve media should work without clean particle impurities valve installed before the proposed filters, Steam pipe installation traps; Electromagnetic valve on the surface of the dirt and filters, to regularly clean.
4．Electromagnetic valve in the event of malfunction, in order to prompt isolation solenoids, and ensure the normal operation, the best bypass device installed. Figure (1). When the solenoid valve installed in the slip road, solenoids than the diameter of the valve Road for a small-caliber figure (2) by-pass device. Note : Extension of the road to close the valve.
5．Do not install the valve in the pipeline low cavity to avoid condensation of water vapor, precipitation and other impurities in the valve and prevent action.
6．Common type solenoid valve, not in regard to the use of dangerous occasions.
7．The lack of rigid pipe, valve before and after the proposed scaffold tubes fixed to prevent electromagnetic valve caused vibration.
8．Electromagnetic valve before and after pipeline installation manometer need to observe the pipeline pressure.
