When it comes to gas solenoid valves, everyone may feel very unfamiliar, but when we see the use of gas, the
Gas solenoid valve will not feel strange. Next, I will tell you about the steps of using the gas solenoid valve.
When the solenoid valve coil is energized, the solenoid valve opens, and at this time the input source of the magnetic switch is in contact with the output open contact, and the input source and the output
The close contact is disconnected, and the coil keeps the solenoid valve in the open state; when the solenoid valve coil is de-energized, the solenoid valve closes quickly, at this time
The input source of the magnetic switch is connected to the output close contact, and the input source is disconnected from the output close contact.
1. The valve installation unit should have corresponding qualifications and install according to the relevant gas pipeline construction specifications.
2. The valve should be installed after the main air intake valve indoors for easy maintenance.
3. It should be installed according to the airflow direction marked on the valve body. The coil of the valve body must not stand upside down, and horizontal and vertical installation are allowed.
4. The solenoid valve control wires should be connected correctly and reliably. The control wires have polarity: the white wire is the positive pole and the black wire is the negative pole, which cannot be reversed.
5. When purging the pipeline, it is recommended to isolate the solenoid valve to prevent the debris in the pipeline from damaging the valve sealing material.
6. Before the pipeline is subjected to pressure test to check the sealing performance, the solenoid valve should be in the open state.
7. When opening the valve manually, it is advisable to operate it when the inlet and outlet pressures of the valve are balanced.
8. When electrically closing the valve, do not connect the wrong power supply, such as: wrong polarity, wrong voltage or long-term power supply, etc., so as not to damage the electromagnetic wire
lock up.
Only by mastering the installation and use of gas solenoid valves can we better protect people's lives and property.
