Correct, the demolition of the gas valve is the gas valve from the spare machine work location, the body upperend in the jaws of a pair of pliers-bed of one side, the seat of the valve body with M8X 25 hexalobular heicobacter of hexalobular head alignment valve set's center position, hupensis the other side of the top in the jaw, to increase the contact area on the screw to prevent bursting valve set, at the same time makes it easy to remove.
气阀正确的，拆卸方法是，把气阀从机器工作位置拆下来，将阀体的一头放在钳台的钳口一边，阀体的阀座边用M8X 25内六角螺杆的内六角头对准阀套的中间位置，螺的另一边顶在钳口上，目的是增加螺杆的接触面积，防止顶破阀套，同时便于取出卡簧。
