Abstract
The utility model relates to a safety protective joint for a gas meter, which is composed of an inverted tooth pipe 1, an inner core 2, and a joint 3 for the gas meter, wherein, one end of the inner core 2 is provided with an inner core protruding edge 4 which forms in a hollow cylinder shape, the other end of the inner core 2 is provided with an inner core baffle plate 5 which forms in a cylinder shape, and the middle part of the inner core 2 is provided with a hollow passage. The inner core protruding edge 4 is positioned between the inverted tooth pipe 1 and the joint 3 of the gas meter; a cylinder which is arranged at the outer side of the inverted tooth pipe 1 is provided with a lead seal hole 6. Compared with the prior art, the utility model has the advantages of compact and simple structure, high safety, reliability, convenient operation, installation and maintenance, etc. The utility model is widely used as a safety joint for the gas meter.
Description
The utility model relates to a kind of gas meter safeguard protection joint of protection pipeline and gas metering table safety.
From security consideration with for the purpose of preventing to steal, leaking gas; adopt antitheft pipe unit at existing gas meter; be to utilize two articulations and two lead sealings; make gas meter and attached pipeline affixed; the protection gas meter is not subjected to artificial destruction; but this complex structure, the cost height, installation, maintenance, use are all inconvenient.In the patent disclosure of number of patent application 91202859.9 " a kind of gas meter water meter measurement anti-theft check apparatus ", also have above-mentioned deficiency.
The purpose of this utility model is to overcome the prior art above shortcomings, and a kind of compact conformation is provided, i.e. safety can be used again, installation, maintenance gas meter safeguard protection easily joint.
Above-mentioned purpose of the present utility model is to realize by such structure, form by pawl pipe, inner core, gas metering meter connector, its inner core one end is the prominent edge of hollow cylinder bodily form inner core, the other end is a Cylinder shape inner core baffle plate, the centre is a hollow passageway, inner core is prominent along being between pawl pipe and the gas metering meter connector, and Cylinder has lead seal hole outside the pawl pipe.When using the utility model, load onto inner core at the gas metering meter connector, the pawl pipe of screwing on again, because the inner core baffle plate can effectively block artificially and practise fraud from the pawl pipe orifice, the pawl pipe has the lead sealing measure simultaneously, gas meter can not arbitrarily be dismantled, effectively prevent to usurp the gas phenomenon and take place.
The utility model said structure can further specify by accompanying drawing.
Accompanying drawing is the utility model structure cross-sectional schematic.
Among the figure: 1-pawl pipe 2-inner core 3-gas metering meter connector 4-inner core is prominent along 5-inner core baffle plate 6-lead seal hole
As shown in drawings, there is screw thread in the utility model gas metering meter connector 3 outer gardens, be threaded with garden in the pawl pipe 1, inner core 2 is between them, inner core 2 one ends have inner core prominent along 4, the other end has inner core baffle plate 5, and it is blast tube that the centre is hollow passageway, on the garden lead seal hole 6 is arranged outside pawl pipe 1 Cylinder.
Pawl pipe 1 also can be made threeway.
Lead seal hole 6 on pawl pipe 1 after the lead sealing, is fixed on pipeline or the wall.
The utility model compared with prior art, its compact conformation is simple, and is safe and reliable, use, install, The advantage such as easy to maintenance. Can be extensively as the gas meter safety joint.
