And, because the valve core assembly 22 has certain weight, the downward slope is easy to produce because of the effect of gravity in the course of moving the valve core assembly 22, thus has influenced the pressure stabilizing effect of the pressure stabilizing membrane 23, the technical scheme of the invention is through setting up the guide 211 in isolating the assembly 21 fixedly, and wear and locate the valve core assembly 22 in the guide 211 movably, guide the movement of the valve core assembly 22 through the guide 211, and reduce the degree of inclination of the valve core assembly 22, reduce because the valve core assembly 22 moves the influence to the pressure stabilizing membrane 23 because of its effect of gravity in the course, has promoted the pressure stabilizing performance of the pressure stabilizing structure 20, guarantee the pressure stabilizing effect of the gas valve device 100.
