The work of liquefied gas pressure reduction valve is controlled by the pressure of the valve.When the pressure sensor detects the increase in the valve pressure indication, the pressure decompression valve valve is reduced; when the pressure reduction valve decreases after detecting the pressure decompression valve, the opening degree of the pressure reducing valve increases to meet the control requirements.LPG pressure reduction valve -The decompression ratio of this valve must be higher than the system value to a certain extent; even at the maximum or minimum traffic it should be able to respond to the control signal of positive or reaction.
Specification of liquefied gas pressure reduction valve
How much is the liquefied gas pressure reduction valve?
According to the difference between the quality and use, the price is between 20 yuan and 80 yuan.There are many types of pressure reduction valves. Common ones are: pilot piston pressure decompression valve, film -type decompression valve, ripple tube pressure decompression valve, proportional pressure decompression valve, self -force pressure decompression valve, direct piston pressure decompression valve, Back pressure regulating valve and so on.They are suitable for different working media.
Principles of liquefied gas pressure reduction valve
The high -pressure cavity and connection of the liquefied gas pressure reduction valve, the low pressure cavity is the exit of gas and leads to the system.The value of the high pressure gauge is the pressure of gas storage in the cylinder.The exit pressure of the low pressure gauge can be controlled by the adjustment screw.When using, open the total switch of the cylinder first, and then rotate the low -voltage meter pressure to adjust the screw clockwise to compress the main spring and drive the thin film, spring cushion and the top rod to open the living door.In this way, the imported high -voltage gases enter the low -voltage chamber from the high voltage chamber after decompression, and the export to the working system.Rotate the adjustment screw to change the height of the living door opening, thereby adjusting the amount of high -pressure gases and reaching the required pressure value.The liquefied gas reduction valve is equipped with a safety valve.It is a device that protects the pressure reduction valve and use it safely, and it is also a signal device for failure valve.If the outlet pressure rises by itself due to damage to the living door and the living door or for other reasons, the safety valve will automatically open the exhaust when the export pressure rises on its own and exceeds a certain permit value.
LNG pressure reduction valve leakage
Bar off the valve, then take the wrench handle first, and then unscrew the first nut to see the skin ring inside. Just hit it and change it.If you do n’t have a leather ring, you can find the raw material belt for connecting tap water, wrap it in a few more circles clockwise, and then re -put the nut and hand wheel.If you are a liquefied gas tank, you cannot repair it. If you have a leakage, you must change the liquefied gas tank.
