Abstract
The utility model discloses a household gas pressure stabilizer which comprises a gas inlet tube, a shell body, a surface shell, a bottom shell, a valve rod, a working diaphragm, a compensation diaphragm and a gas outlet tube; the household gas pressure stabilizer is characterized in that a cavity body is formed between the working diaphragm and the compensation diaphragm, the cavity is communicated with the cavity body of the bottom shell and the cavity body of the bottom shell is communicated with the gas outlet tube. As the working diaphragm, the compensation diaphragm and the valve rod are arranged in the shell body, the output pressure in the outlet is regulated through the regulation effect of vertical displacement of the working diaphragm and the compensation diaphragm on the valve rod so that the output pressure can satisfy the pressure demands of gas appliance. Compared with conventional lever transmission and single diaphragm stabilizer, the double-diaphragm structure stabilizer not only can be suitable for lower gas source pressure, but also can have good response speed and stability. Besides, parts contacted with gas are all made of non-metal material and the influence on service life of parts due to corrosion of biogas is avoided.
