Solenoid valve maintenance and installation instructions
Solenoid valve use and maintenance: 1, it is recommended to use the unit to assign someone responsible for the use and maintenance 2, 1-2 times a year regular maintenance is the solenoid valve reliable work and longevity of the best way. Solenoid valve within the following four kinds of situations, is to prevent the normal operation of the solenoid valve and shorten the life of reason. ⑴, the media used in the change ⑵, taking over the rust ⑶, air compressor oil oxidation, resulting in carbon tar and other debris, mixed with pipe 2.4 Dust and other impurities in the pipeline 3, the solenoid valve installed or a long time Discontinued, put into operation again after the media into the trial to try a few times to work properly before the official use 4, the steam valve for a long time after deactivation put into operation, should drain net condensate after the trial move several times before normal work put into service. 5, before maintenance, you must cut off the power, remove the media pressure. 6, the coil assembly should not be opened 7, open the solenoid valve for cleaning, you can use kerosene `trichlorethylene solution, etc., but should pay attention to the rubber may dissolve So, it should be replaced. 8, open the cleaning, the parts should be restored in order to restore the status quo installed. 9, my company with wearing parts, if necessary, please specify when ordering according to the instructions. Order, wearing parts and other matters are not yet available, please consult Technical Department. Solenoid valve installation instructions: 1. Before installation, you should carefully read the manual of the product, check whether the product fully meets the requirements of use, be familiar with the installation points, and make preparations. 2. Install the solenoid valve coil up, and maintain a vertical position, the solenoid valve arrow or mark should be consistent with the flow of the pipeline shall not be installed in a place splashing water or water leakage. 3. 0.3MPa before taking over the full flushing of the pipeline, the pipeline of metal powder sealing material residues, rust and other completely clear; solenoid valve working medium should be clean without impurities, it is recommended to install filters before the valve, steam pipe installation Traps; Solenoid valve on the surface of the dirt and filters, to be regularly cleaned. 4. In the solenoid valve failure, in order to promptly isolate the solenoid valve, and to ensure the normal operation of the system, it is best to install a bypass device. When the solenoid valve is installed in the branch, the diameter of the solenoid valve should be smaller than the diameter of the main pipeline valve. Note: The valve on the branch must be closed. 5. Do not install the valve in the low recess of the pipe to avoid condensation of water vapor, impurities and other precipitation in the valve and impede the action. 6. Ordinary solenoid valve can not be used in flammable and explosive dangerous situations. 7. In the case of inadequate pipeline rigidity, it is recommended to fix the pipe before and after the pipe with a bracket to prevent vibration when the solenoid valve works. 8. Solenoid valve before and after the pipeline to be installed on the pressure gauge, in order to observe the pipeline pressure
