Gas solenoid valve is still familiar to most of our friends, gas solenoid valve is also called gas taboo shut-off valve, it is mainly used in city gas, natural gas and liquefied petroleum gas, in addition to gas solenoid valve is widely used in the textile industry, printing industry and gas qualitative industry, light bulb industry and so on. Generally, the gas solenoid valve is more suitable for gas, and its material is also very good, which belongs to NBR rubber. Moreover, the technology used in the gas solenoid valve is also very advanced, so let's talk about the knowledge of the gas solenoid valve.
Gas solenoid valve**
Gas solenoid valve, also known as gas emergency shut-off valve, is an actuator suitable for two-position on-off switching and automatic temperature control of city gas, liquefied petroleum gas, natural gas and other coal gases for heating and combustion medium pipelines. It is widely used in the automatic control system of gas heating in the textile industry and printing industry, kiln heating in glass and light bulb industry and other industries.
The working principle of gas solenoid valves
The cold water enters the water heater, flows through the water-gas linkage valve body, and under the action of a certain pressure difference of the flowing water, pushes the water-gas linkage valve, and pushes the micro switch to turn on the power supply and start the pulse controller, open the gas ventilation solenoid valve, and ignite the gas water heater to burn the burner; After the burner is ignited, the flame detection element gives a flame signal to the pulse controller by detecting the flame, and opens the solenoid valve by maintaining the current to maintain the normal combustion of the burner. If the ignition fails, the pulse igniter cannot maintain the normal opening of the solenoid valve because it does not detect the maintenance current signal of the flame, close the solenoid valve, and cut off the gas **.
The role of the solenoid valve of the gas water heater:
Clause. First, the solenoid valve plays the role of a water vapor linkage, water and electricity, ventilation, and double protection. The normal startup procedure to follow is:
The water is turned on first, and then the micro switch is started, the whole machine is energized, and then the ignition, after ignition for 1 3 seconds, the solenoid valve is engaged, ventilated, and burned. If the solenoid valve is lost, when the water is connected, that is, it is ventilated, and if the ignition is delayed, when the gas fills the combustion chamber, deflagration will occur, bringing potential safety hazards.
Second: the double protection of the water heater, that is, when the water pressure starts, the water film is affected by the water pressure, and at the same time, the power supply of the whole machine is turned on while pushing to the left, and at the same time, a spring top cover is also put on the top of the middle yard to the left. (This is another switch to control the air source), it is a mechanical action, if there is a residue in the water film, after the scale, if the water film is not in place, and you do not use the solenoid valve, it will leak and cause a safety accident.
The status of gas solenoid valve in our life has been higher, and its appearance has greatly improved the safety of our lives. And it also saved a lot of lives. The gas solenoid valve is actually a tool used to control the excessive concentration of gas in the air, which can lead to the danger of people's lives.
The work of the gas solenoid valve is also very simple, it is by sensing the external situation, and then making an adjustment to its own circuit to achieve a very good effect, which greatly reduces the safety risk of gas.

1.Before installation, you should carefully read the instruction manual of the product, check whether the product fully meets the requirements of use, be familiar with the installation points, and make preparations. 2.
When taking over, care should be taken that the sealing material should not be used in excess. If the thread is connected, the pipe thread should be kept within the effective length, and the end half pitch is chamfered with a file, and the sealing tape is wound from the end at 2 teeth, otherwise the excess sealing tape or adhesive will enter the solenoid valve, and the accident that hinders the normal operation will occur. 3.
There should be a certain amount of reserved space at the installation place of the solenoid valve for its daily maintenance and regular maintenance. 4.When installing, fix the valve body with a wrench or pipe wrench, and then screw on the pipe, and do not force the first ring assembly to cause deformation, so that the solenoid valve is difficult to work normally.
5.In the case of insufficient rigidity of the pipeline, or water hammer, please fix the front and rear pipes of the valve firmly with brackets. 6.
When used in frozen places, the pipes are protected with thermal insulation materials or heaters are installed on the pipes. 7.Check whether there is any leakage in the solenoid valve itself and its connection to the pipe.
8.Check the connection of the coil lead-out wire, especially when there are three lead-out wires. 9.
Electrical components connected to solenoid valves, such as relays, switches, and contactors. The contact should not vibrate when the valve is opened, otherwise the work will be unreliable and affect the life of the solenoid valve. 10.
The electrical circuit should be connected to the corresponding safety line as the protection of the electrical circuit. 11.In order to facilitate maintenance and repair operations, or to ensure that continuous production is not interrupted, the bypass isolation installation method is recommended for general solenoid valves.
12.Generally, the solenoid coil parts of the solenoid valve should be upright and perpendicular to the pipeline, some products have special regulations, please install them according to the instructions. 13.
Check whether the parameters marked on the nameplate are the parameters of the selected product and whether they are consistent with the instruction manual. 14.The pressure used before taking over the pipe is fully flushed, and the metal powder, residual sealing material, rust and scale in the pipe are completely removed.
15.Pay attention to the cleanliness of the medium, if the dust and dirt and other impurities mixed in the medium hinder the normal operation of the solenoid valve, the pipeline should be equipped with a filter. 16.
The solenoid valve should not be installed in the low recess of the pipeline, such as in the discharge pipe of the container, pay attention not to lead out from the bottom of the container, but should be installed at the bottom of the container slightly above the position. 17.If the medium will cause water hammer, then a multi-function solenoid valve should be used or corresponding precautions should be taken.
18.The inlet side of the steam solenoid valve should be equipped with a trap, the pipe should be tilted, the trap should be installed in a low position, and it is best to install a multi-way backflush filter. 19.
The solenoid valve is generally directional, can not be installed in reverse, usually on the valve body with the "arrow" to indicate the direction of the medium flow, installation should be in accordance with the "arrow" direction of installation.
