The gas pressure regulating valve is a straight pole and leveraged pressure difference feedback to control the pressure regulation.The gas in the gas cylinder is liquid, and the pressure is too high. It must be reduced to the furnace burning.The gas pressure regulating valve must be replaced with a new one.Classified according to the methods and functions of use, main parameters, pressure, media work temperature, special use (that is, special, special valve), driver energy, structure, etc. The most commonly used classification method is to divide the regulating valve into nine according to the structure.The large category, 6 types are straight strokes, and 3 are corner itineraries.
Gas pressure regulating valve price
The gas pressure regulating valve with explosion -proof devices is made of thickened zinc alloy valve body. In addition, a high -temperature spray paint process is used, which makes the appearance particularly delicate, and it will not be painted even if it is used for a long time.At the same time, it also uses a thickened all -copper hand wheel design. The thread is particularly accurate. It is also particularly convenient during installation. It has a long service life.It also has a high -end LPG pressure gauge, which is made of copper, which can accurately display the gas pressure in the bottle.Then the reference price of the gas pressure regulating valve with an explosion -proof device is about 60 yuan.The crown gas pressure regulating valve uses imported all -copper nets. The quality is stable and reliable, relatively durable, and can also effectively filter some impurities in the gas to enhance its service life. At the same time, the gas in the gas stove burns even morefull.There are also high -level sealing items, and the sealing degree is very good.His decompression valve body uses a stainless steel thread design, which has the advantages of corrosion resistance.It is particularly safe to use.The reference price of this crown gas regulation valve is about 80 yuan.MADAS gas pressure regulating valve uses a double -band valve and has its own gas pressure meter, which shows that it is particularly accurate and clear. It can automatically regulate the gas pressure. The operation is also very convenient.Safety.The reference price of this Madas gas pressure regulating valve is around 100 yuan.

Principles of gas pressure regulating valve
The working principle of the gas pressure regulating valve is that the high -pressure medium is charged to a relatively large cavity through a small hole to achieve decompression. In fact, it depends on the decompression of the interception. The two sides of the film or the piston are exportedPressure, and control the small pore size valve stems and membrane (piston), so as to give a fixed pressure, then the pressure of the export cavity will always be equal to this pressure.Or the hydraulic source to provide.
