Description
Technical field
The utility model relates to gas meter, flow meter technical field, specifically a kind of card insert type lock ring anticreep gas meter, flow meter.
Background technology
Along with the development of science and technology, natural gas uses widely industry, business and civilian being obtained for.But some businessmans are under interests drive, privately gas meter, flow meter is overlapped, wherein mostly being the tracheae private of taking off meter connector receives on the pipeline oneself built, the pipeline of putting up in disorder carries out accounting management in Shi Bu aspect gas company on the one hand, the more important thing is that these pipelines do not have safety guarantee, and easily occur reveal thus cause security incident.
Utility model content
The utility model aims to provide a kind of card insert type lock ring anticreep gas meter, flow meter, by providing protection to gas meter connector part, to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of card insert type lock ring anticreep gas meter, flow meter, is characterized in that: comprise gas meter, flow meter, meter connector containment vessel, the meter connector be connected on shell of gas meter; Described meter connector containment vessel comprises the chassis be weldingly fixed on gas meter, flow meter, chassis has the jack of meter connector, is provided with turbination limiting stand in the middle part of jack; Meter connector containment vessel also comprises the tubular meter connector protective cover be connected in jack, and protective cover excircle has annular groove, arranges and has multiple counter sink, be connected with socket head cap screw in each counter sink in annular groove; Described chassis excircle has adjustment hole, and the size of adjustment hole is less than the maximum outside diameter of socket head cap screw; Described meter connector is connected with cutting ferrule, is provided with tracheae protection pipe in cutting ferrule; Described cutting ferrule comprises set nut, clamping joint, clamping device, and clamping device is welded on set nut, and leaves space between set nut and clamping device; Described clamping joint is provided with taper surface, and one end that clamping device contacts with clamping joint is also provided with the conical surface; The axial angle of the conical surface of described clamping joint is greater than the axial angle of the conical surface of clamping device.
Further, described gas meter, flow meter side is provided with card slot.
Further, described gas meter, flow meter front surface is provided with Meter Reading Device.
The beneficial effects of the utility model are:
One, the utility model in use, and first tightened by the socket head cap screw in the protective cover counter sink of tubular, then be inserted in jack by roll boot, now socket head cap screw is embedded in counter sink completely, can pass through turbination limiting stand smoothly; After protective cover puts in place, stretch into allen key outwards twisted one by one by screw from adjustment hole, protective cover is stuck in hole cannot be taken out.Simple to operate, economical and practical.
Two, secondly, the utility model is provided with cutting ferrule, when set nut constantly inwardly screws, it can promote clamping device constantly towards clamping joint motion, until two conical surfaces start extruding, because the tapering of two conical surfaces is not identical, its contact portion starts as single-point, and it can produce radial force in extrusion process, and the axial angle of the conical surface of clamping joint is greater than the design of the axial angle of the conical surface of clamping device, ensure that produced radial force is towards gas passage, also just creates clamping force.Tracheae protection pipe can produce certain deformation under the effect of clamping force, makes it more difficultly come off, never prevent pipeline from being connect by private by deformation.
