Described first plane is provided with the detent of horizontally set, and described three-axis body is provided with the second plane, described second plane
With the first parallel connection of plane so that three-axis body is away from forming a boss at the first plane.
Further, described first plane is extended near three-axis body one end by near the first axle body one end, described location
Groove system is formed to the second axle body axis direction depression by the first plane, and the lateral length phase of its lateral length and the first plane
Deng.
Further, curved setting bottom described detent.
Further, the longitudinal length of described second plane is more than the length of side of three-axis body longitudinal section, less than the first plane
Longitudinally wide.
Further, the periphery of described 5th axis body is provided with a pair the 3rd planes arranged according to its axisymmetrical, and described
Three planes and the first plane parallel, described 5th axis body is provided with through hole, and the center of the 3rd plane is connected by described through hole with this
Line is perpendicular.
During use, the 5th axis body abuts against with diaphragm, and the first axle body is arranged with spring, and three-axis body is near the 4th axis body
Side is docked with sealing valve port, and arranges the locating piece suitable with detent in the valve body being provided with spring, and locating piece is inserted
Being located in detent, when the pressure differential of diaphragm both sides increases, electronical line shaft moves toward spring direction and compression spring, electronical line shaft
Axis body is separated with valve port, thus supplies combustion gas by valve port, when the pressure difference ends of diaphragm both sides, under the action of the spring
Resetting, electronical line shaft axis body abuts with sealing valve port, cuts off gas supply, and no matter the normal use of protection gas heater is pressure
Contracting spring still resets, and locating piece is inserted in detent all the time, so that electronical line shaft occurs without rotation phenomenon.
Compared with prior art, the beneficial effects of the utility model are: by the improvement of said structure, electronical line shaft is running
During occur without rotation phenomenon, it is ensured that reset time three-axis body coordinate with the sealing of valve port, it is ensured that the use of equipment is steady
Qualitative, extend service life, reduce use cost.
