Abstract

The invention discloses a gas valve, which comprises a valve body and a casing. The valve body and the casing form a valve chamber. The valve body is provided with an air inlet chamber and an air outlet chamber. A valve membrane mechanism is installed in the valve body. The cavity is divided into a balance cavity and a decompression cavity connected with the outlet cavity. The decompression cavity communicates with the intake cavity through a spool hole. The spool for opening and closing the spool hole, the shell includes an upper shell installed on the valve body, and an adjusting nut threadedly connected with the upper shell, and a large spring acting on the wall of the upper shell is arranged inside the balance chamber, and can act For the small spring of the adjusting nut, one end of the adjusting nut is a cavity for giving way to the small spring, and the other end is provided with a blocking wall that can interact with the small spring. By adjusting the installation method of the nut, two air pressure modes can be selected, so that there is no need to replace the gas valve when changing the type of gas used, and the purpose of using different gases alternately is achieved, which is convenient, quick and widely used.

Description

technical field [0001] The invention relates to the field of fluid valves, in particular to a gas valve with adjustable pressure. Background technique [0002] Generally, the gases we use for combustion include liquefied petroleum gas and natural gas. Different gases have different calorific values ​​and different pressures. Usually, the pressure of liquefied petroleum gas is as high as 2800p, while the pressure of natural gas is as small as 2000p. Therefore, the two Gas matching gas valve specifications are also different. In daily life, when one of the liquefied petroleum gas or natural gas is used up or stops supplying, people need to replace it with another one. At this time, the gas valve needs to be replaced in addition to the gas pipe. The replacement process is complicated. Life is inconvenient. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. The...
