Abstract
The utility model discloses a gas meter built-in explosion-proof tongue tube valve. The valve is integrally installed inside the gas meter, which comprises an engine seat, a supporting plate, a bracket, a valve plug, a transmission gear, a spring and an output gear; the engine seat is connected with the valve plug through the supporting plate, and the bracket is arranged on the valve plug; a motor arranged inside the engine seat is connected with a valve bolt with the outer part being sleeved with the spring and arranged inside the valve plug through the output gear and the transmission gear. An explosion-proof circuit board is also adjacently arranged on the outer side of the engine seat. The engine seat is fixed with the valve plug together through the supporting plate with screws, and a tongue tube is arranged on a dummy club fixed by screw. The gas meter built-in explosion-proof tongue tube valve has the advantages that the valve is integrally installed inside the gas meter, the structure is reasonable, exterior space is not occupied, and the valve has the functions of switch valve automatically detecting and explosion protection, and the operation is more secure.
Description
Technical field
The utility model relates to a kind of valve, the built-in explosion-proof dry reed-pipe valve of specifically a kind of gas meter.
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 coefficient is little, do not have automatic detecting switch valve, do not have explosion prevention function, use dangerous, 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 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.
The technological scheme that its technical problem that solves the utility model adopts is: the built-in explosion-proof dry reed-pipe valve of a kind of gas meter, 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.
The adjacent intrinsically safe circuit plate that also is provided with in the described support outside.
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.
