How to use the gas cut-off solenoid valve, gas cut-off solenoid valve installation and wiring instructions

How to use the gas cut-off solenoid valve 1. There are two ways to close the valve when it is open: ① Provide an instantaneous DC pulse (DC 9~12V) power to the solenoid coil (about 1 second), and the solenoid valve will quickly close;② Open the protection cover, and the valve can also be closed by manually pressing the red handle. The status is maintained after closing the valve. Note: Under normal circumstances, it is not advisable to open the protective cover to avoid closing the valve by mistake. 2. There is only one way to open the valve when it is closed: manually pull up the red handle to open the valve. The open valve state can be self-maintained. Note: When opening the valve, if it is difficult to lift the handle upward, measures should be taken to balance the inlet and outlet pressures at both ends of the valve, and then open the valve after balancing. Avoid rough operations to avoid damaging the valve opening actuator. 3. The valve is in an open state: Due to the magnetic lock principle design, when the valve encounters harmful strong vibrations, the valve may automatically close, which is normal. If the valve opening self-locking force is abnormal (too small), the manufacturer should be notified for repair. 4. When the valve is cut off in an emergency, it must be manually confirmed on site and the hidden dangers of the accident can be eliminated before it can be manually reset and ventilation resumed. Instructions for installation and wiring of gas cut-off solenoid valve 1. The valve installation unit should have corresponding qualifications and install according to relevant gas pipeline construction specifications. 2. The valve should be installed behind the main indoor air inlet valve for easy maintenance. 3. It should be installed according to the air flow direction marked on the valve body. The valve body coil must not be inverted. Horizontal and vertical installation are allowed. 4. The control wire of the solenoid valve should be connected correctly and reliably. The control wire has polarity: the white wire is the positive pole and the black wire is the negative pole. They cannot be connected reversely. 5. When purging the pipeline, it is recommended to isolate the solenoid valve to prevent debris in the pipe from damaging the valve sealing material. 6. Before performing a pressure test to check the sealing performance of the pipeline, the solenoid valve should be opened first. 7. When opening the valve manually, it should be operated when the pressure at the valve inlet and outlet is balanced. 8. When closing the valve electrically, be sure not to connect the wrong power source, such as wrong polarity, wrong voltage, or long-term power supply, to avoid damaging the solenoid coil. Installation guide for household emergency cut-off solenoid valve Wiring requirements Cable wire: It is recommended to use double-core protective conductor 2×0.75mm2, and terminal crimping method is used for wiring;control distance: capacitor discharge drive method, wiring length is less than 50 meters. For valve maintenance, it is recommended that users regularly check the opening and closing of the valve. If a fault is found, the professional or manufacturer should be notified in time for maintenance. The above is how to use the gas cut-off solenoid valve, and the installation and wiring instructions of the gas cut-off solenoid valve.
