Abstract
The utility model discloses a gas meter built-in screw type explosion-proof reed switch valve which is integrally arranged inside a gas meter. The valve comprises a frame, a support plate, a bracket, a valve plug, a driving gear, a spring and an output gear, wherein, the frame is connected with the valve plug through the support plate; the bracket is arranged above the valve plug; a motor arranged inside the frame is connected with a vent pin which is arranged in the valve plug and sleeved with a spring outside through the output gear and the driving gear; an explosion-proof circuit board is arranged on the outer side of and adjacent to the frame; the frame is fixed with the valve plug through the support plate by bolts; and a reed switch is arranged above a lug boss at the position for fixing with the bolt. The gas meter built-in screw type explosion-proof reed switch valve is arranged inside the gas meter, has reasonable structure, and occupies no exterior space. The gas meter built-in screw type explosion-proof reed switch valve has the functions of the automatic detection of the switch valve and explosion-proofness, which is used more safely. The motor is sealed with a screw type frame cover, thus installing more conveniently.
Description
Technical field
The utility model relates to a kind of valve, the explosion-proof dry reed-pipe valve of specifically a kind of gas meter built-in screw type.
Background technique
What at present most gas meter all used is external valve, and it is big to take up room, unreasonable structure, and safety is all little, do not have automatic detecting switch valve, do not have explosion prevention function, use dangerous, most important be, when keeping in repair motor if desired, need the demountor flap, but the support lid is because its structural reason, suchlike drawback is not easy dismounting and installation, so must solve.This product is installed in gas meter inside, does not take space outerpace, uses safer.
The model utility content
Technical problem to be solved of the present utility model is at the prior art deficiency, provides a kind of gas meter built-in screw type explosion-proof dry reed-pipe valve, and it is little to occupy the space, and structure is more reasonable, has automatic detecting switch valve function and explosion prevention function, and is safe in utilization; Motor uses spiral support cap seal mouth, installs more convenient.
The technological scheme that its technical problem that solves the utility model adopts is: the explosion-proof dry reed-pipe valve of a kind of gas meter built-in screw type, described valve integral installation is in gas meter inside, and described valve comprises support, dunnage, support, valve plug, driving gear, spring, output gear; Described support is connected with valve plug by dunnage, is provided with support above the described valve plug; The motor of described base inner is connected by the bibcock that output gear and driving gear and outside in being arranged on valve plug are with spring.
Described support bottom is provided with the support lid; Described support top is provided with back-up ring.
Described support lid is spirality.
The support base inner of described motor top also is provided with the intrinsically safe circuit plate.
Described support is screwed together by dunnage and valve plug, is provided with dry reed-pipe above the convex at described screw place; Described valve plug one side margin place also is provided with small gear.
The explosion-proof dry reed-pipe valve of a kind of gas meter built-in screw type of the present utility model is compared with prior art, has following beneficial effect:
The explosion-proof dry reed-pipe valve of a kind of gas meter built-in screw type of the utility model is installed in gas meter inside, and is rational in infrastructure, do not take space outerpace, has automatic detecting switch valve function and explosion prevention function, uses safer.Motor uses spiral support cap seal mouth, installs more convenient.
