Abstract
The utility model relates to a valve rod limiting structure of a gas plug valve. The valve rod limiting structure comprises a valve rod arranged on a valve casing in a penetrating mode. The valve rod limiting structure is characterized in that a shell which is fixedly arranged relative to the valve casing is included, the valve rod penetrates through a shaft hole in the shell and can rotate around the axis of the valve rod, and a shaft groove matching structure is arranged between the valve rod and the inner wall of the shaft hole; when the valve rod is in an initial state, a limiting shaft in the shaft groove matching structure is located in a limiting groove so that the valve rod can be limited axially and cannot move downwards; when the valve rod rotates, the limiting shaft in the shaft groove matching structure can slide along the limiting groove; when the valve rod rotates to be at 90 degrees, the limiting shaft in the shaft groove matching structure is not limited by the limiting groove so that the valve rod can move up and down. According to the valve rod limiting structure, the valve rod can be freely rotated, only when the valve rod rotates to be at 90 degrees can the valve rod get rid of limiting and press downwards to ignite, during igniting, pressing and rotating are separated to be two independent steps, a key-type igniting experience is created, igniting operations are convenient to carry out and the operation experience is better.

A kind of valve stem spacing structure as just disclosed in the patent No. Chinese utility model patent " a kind of fuel gas plug valve " that is ZL200920191607.7 (notification number is CN201487275U).
Summary of the invention
Technical problem to be solved in the utility model is that a kind of valve stem spacing structure that can allow the convenient fuel gas plug valve of ignition operation is provided for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of valve stem spacing structure of fuel gas plug valve, comprise the valve rod being located on valve casing, it is characterized in that: also comprise the housing that relative valve casing is fixedly installed, valve rod also can be around self axis rotation through the axis hole on housing, between valve rod and shaft hole inner wall, be provided with axial trough cooperating structure, under valve rod original state, position-limited shaft in axial trough cooperating structure is positioned at restraining groove and valve rod can not be moved down by axial limiting, in valve rod rotary course, position-limited shaft in axial trough cooperating structure can be along restraining groove slippage, rotate to the state of 90 degree at valve rod, position-limited shaft in axial trough cooperating structure departs from the constraint of restraining groove and valve rod can be moved up and down.
Above-mentioned valve rod has D oblique crank Z portion, this D oblique crank Z portion is located in the axis hole on described housing, position-limited shaft in described axial trough cooperating structure is arranged on the madial wall of axis hole, restraining groove in described axial trough cooperating structure is arranged on the arc shaped surface of D oblique crank Z portion and is curved, and the tool cutting edge plane of D oblique crank Z portion is run through at the two ends of restraining groove.Restraining groove is adapted at processing on valve rod, and position-limited shaft facilitates at the axis hole madial wall of housing and molds, and axial trough position can exchange certainly.
The sidewall of above-mentioned housing has two outward extending installation feet, on the upper-end surface of described valve casing, is fixed with support, and described installation foot is fixed on this support by screw.Certainly also housing directly can be fixed on valve casing.
Compared with prior art, the utility model has the advantage of: this valve stem spacing structure can rotate freely valve rod, but only in the time rotating to 90 degree position, valve rod just departs from and spacingly can press down igniting, in the time of igniting, will press and become two independently steps with rotating stripping on the one hand, provide a kind of touch-tone igniting to experience, not only ignition operation is more convenient, and operating experience is better; Realize on the other hand safe child's lock, the Der Grundsatz der Maschinen that this 90 degree just can press down use is two parts that use convex-concave to coordinate, and 90 couplings of convex-concave while spending can press down, and other positions are not mated and can not be pressed down.
