What does the gas solenoid valve look like when it is open? Gas solenoid valve installation methods and precautions

How does the gas solenoid valve open? 1. After the valve core in the AB valve is turned open, turn the valve 90 degrees to open the valve. The solenoid valve has a pull-in button, also called a pull handle. When the HD2000 natural gas alarm is moved, the solenoid valve will be pulled in to close the gas source. If the crisis is resolved, you need to manually pull the extension handle before you can use gas. 2. The solenoid valve includes (coil, magnet, ejector rod). When the coil is connected to current, it generates magnetism and attracts each other to the magnet, and the magnet pulls the ejector rod. When the power is turned off, the magnet and ejector rod are reset, so that the solenoid valve completes the working process. This is how a solenoid valve works. Solenoid valves are generally used in hydraulic systems to close and open oil lines. 3. The gas solenoid valve is a safety emergency cut-off device for gas pipelines. It can be connected to the gas leakage alarm system or to the fire protection and other intelligent alarm control terminal modules to achieve on-site or remote automatic/manual emergency cut-off of the gas source to ensure gas consumption. Safety. When harmful strong vibration occurs, the valve will automatically close. Gas solenoid valve installation methods and precautions 1. First, align the pipes at both ends, vertically connect the end faces parallel, and use spot welding to position the solenoid valve to ensure the sealing of the solenoid valve. 2. In order to prevent internal parts from being damaged by heat, dismantle the valve body and then weld it. After welding, remove welding slag and oxides to prevent channel blockage. 3. Check and remove burrs or dirt on the sealing line connecting the solenoid pilot valve and the main valve to avoid scratching the soft aluminum sheet and causing loose sealing. 4. When connecting the solenoid pilot valve to the main valve, do not apply too much force, otherwise the five-hole aluminum sheet in the middle will be biased, causing the through hole to become smaller or sealed and unable to conduct. 5. The magnetic isolation bushing flange and the pilot valve seat are sealed by a gasket. When tightening the screws, they should be tightened diagonally. Uneven force will cause leakage. 6. First, check whether the working environment of the gas solenoid valve product meets the working conditions, including temperature, pressure, medium properties, etc. Check whether the parts of the solenoid valve product itself lack structural stability. Generally, the coil is in the same direction as the horizontal pipe, except for special models. If you are a novice, please read the manual carefully before installation. 7. Check the cleanliness of the working environment and internal parts to ensure that there are no visible debris. If large debris enters the solenoid valve during work, it will cause certain damage to the solenoid valve. 8. Install pressure gauges at key parts of explosion-proof gas solenoid valve products. And pay attention to monitoring the pipeline pressure of the solenoid valve. Once it exceeds the standard, corresponding measures must be taken promptly to avoid unnecessary losses caused by accidents. 9. When installing the gas solenoid valve, pay attention to the arrow mark on the valve body. It indicates the direction of medium transmission. Of course, it can be ignored in special circumstances. 10. Gas solenoid valves generally have two types: normally open type and normally closed type. They cannot be used interchangeably, otherwise it will easily cause damage to the solenoid valve and reduce the service life of the solenoid valve. The above is an introduction to how the gas solenoid valve is opened, the gas solenoid valve installation method and precautions.
