Notes for installation of solenoid valve
1, first check whether the solenoid valve is consistent with the selection parameters, such as power supply voltage, medium pressure, voltage difference, etc., especially the power supply, if wrong, will burn out the coil. The power supply voltage should meet the rated voltage fluctuation range: ac +10%~-15%, dc +10%~-10%, the coil assembly should not be disassembled at ordinary times.
2. Before taking over the pipe, wash the pipe to remove metal powder, sealing material residue and rust. Attention should be paid to the cleanliness of the medium, if the medium is mixed with dirt, impurities and other obstacles to the normal work of the solenoid valve, the pipeline should be installed with a filter or mesh.
3, the general solenoid valve solenoid coil components should be vertical upward, vertical installation in the horizontal pipe on the ground, if limited by space or operating conditions must be installed on the side, when the selection of the order. Otherwise the solenoid valve may not work properly.
4, the solenoid valve should be added before and after the manual cut off valve, at the same time should be set up bypass, easy to maintain the solenoid valve in case of failure.
5, solenoid valve is generally directional, can not be installed backwards, usually in the valve body with → pointing out the direction of medium flow, the installation should be in accordance with the → indicated direction of installation. But in the vacuum pipeline or special circumstances can be installed back.
6, if the media will be water hammer phenomenon, then should choose a waterproof hammer function of the solenoid valve or take corresponding preventive measures.
7, try not to let the solenoid valve in the state of power for a long time, so easy to reduce the service life of the coil or even burn out the coil, that is to say, normally open, normally closed solenoid valve is not interchangeable use.
8, steam electromagnetic valve inlet side should be equipped with a trap, the pipe should be inclined.
1.The threaded interface around the ribbons
2.According to the direction of access to the solenoid valve
3.According to the standard access power supply
4.Detection of sealing and circuit
