State the medial surface of the lateral surface of movable plate and the valve pipe slidably and be tightly connected, the inner and movement of the bursting tube
The lateral surface of plate is fixedly connected, and through hole is provided with the fixed cylinder, and the second end of the bursting tube is arranged on the through hole
It is interior, stomata is provided with the movable plate, the blind hole connected with the stomata is provided with the bursting tube, outside the blind hole
End is provided with the steam vent set along the bursting tube radius, and the lateral surface that the spring is arranged on the movable plate is solid with described
Determine between the medial surface of cylinder.
Specifically, the valve pipe, the movable plate, the fixed cylinder, the bursting tube, the through hole, the stomata
It is coaxially disposed with the blind hole.
Specifically, when spring is in non-compressed state, the steam vent of the bursting tube is located at the logical of the fixed cylinder
In hole, the medial surface palette of the steam vent and the through hole；When spring is in most compressed state, the blast pipe
It is arranged on outside the outer end of the fixed cylinder.
Specifically, the chute with the axis parallel of the valve pipe is provided with the valve pipe, is set on the movable plate
There is the sliding block being adapted to the chute, the sliding block is sealed and slidable connection with the chute.
The beneficial effects of the utility model are：
A kind of automatic pressure-controlled gas valve of the utility model is total to by spring, voltage stabilizing inside cavity pressure and atmospheric pressure
Same-action, the movement of control movable plate and bursting tube makes voltage stabilizing inside cavity with outside atmosphere even by the movement of bursting tube
It is logical to switch and isolation between, so that realize stablizing the purpose of voltage stabilizing inside cavity pressure, and simple structure, it is easy to repair and pacifies
Dress.
Brief description of the drawings
Fig. 1 is a kind of structural representation of automatic pressure-controlled gas valve described in the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of automatic pressure-controlled gas valve of the utility model, including valve pipe 1, movable plate 2, fixed cylinder 3,
