The reasonable installation, use and maintenance of solenoid valve is the guarantee of its reliable operation. But the type of solenoid valve is complex and its main use is different. Therefore, basic guidelines for installation and maintenance cannot be listed.
(1) During installation and installation, attention should be paid to the inflow of materials during the working period, and the commodity circulation direction indicated by arrow should be installed on the oil circuit board. The power supply standard of the power supply system shall meet the requirements of the electromagnetic valve nameplates such as communication, DC, rated voltage, output power, etc. According to the control relay driver, this should be valid for. The solenoid should be grounded for safety. The solenoid valve is equipped with elastic yellow, which can withstand certain vibration level, light vertical installation and all normal operation, but should be installed as low as possible in terms of vibration and vertical installation. Pay attention to the connection position with the valve and the tightness of the valve itself to avoid leakage. In the workplace with corrosive substances, outdoor installation, solution valve to take necessary protection measures.
(2) Check and repair the solenoid valve installed in the new pipeline, and purge the pipeline with pretreatment process to remove the residue, dirt and welding in the pipeline to prevent the valve from blocking or jamming. When the process stops without solenoid valve, the manual stop before closing the valve should be performed. If the shutdown time is too long, the solenoid valve can be brought into the valve for disassembly and storage, or the valve can not work due to the serious proportion of processing pipeline in the valve. It's easier and more aggressive to consider reducing storage than working hours to solve common failures. It is also important to prepare the necessary spare parts in advance. Because the structure of solenoid valve is not too complex, it is not too difficult to solve common faults. The following are some common problems, such as power supply but solenoid valve does not work, should check whether the circuit is normal, otherwise check whether the coil is broken. The power supply valve cannot be opened, and the screw of check valve cover is loose. If the replacement bonnet gasket is removed after this common failure occurs, check whether the gasket is too thick or too thin, or the problem caused by inconsistent screw loosening level. The other is to check whether the plug is dead, and the tester should see if the valve is blocked. After the power is turned off, the valve cannot be closed. Check whether the valve plug is closed and the pilot valve is blocked. The valve has been closed, but it has not been closed. There is still material leakage during operation, the gasket of key check valve plug is damaged, and the valve of high-pressure gate valve is loose.
