Abstract
The utility model discloses a gas meter capable of preventing fraudulent use of gas. The gas meter capable of preventing fraudulent use of gas comprises an outer housing and a metering core, wherein the metering core is disposed inside the outer housing. The outer housing is provided with a gas inlet joint and a gas outlet joint. The metering core is provided with a gas inlet and a gas outlet. The gas inlet of the metering core is communicated with the inside of the outer housing. A gas outlet of a gas outlet pipe is connected below the gas outlet joint, and a gas inlet of the gas outlet pipe is connected with the gas outlet of the metering core. The gas meter capable of preventing fraudulent use of gas is characterized in that a through-hole at the center of the gas outlet pipe is sleeved an inner sleeve pipe; and the top of the inner sleeve pipe curls outward into a shape of a bell and is mated with the gas outlet of the gas outlet pipe. The obvious effects are that the gas meter of the utility model can prevent fraudulent use of gas and gas leakage, the inner sleeve pipe has a simple structure, the gas meter is convenient in mounting and cost is low.
Description
Technical field
The utility model relates to measuring apparatus, especially a kind of anti-theft gas gas meter, flow meter.
Background technology
Gas meter, flow meter is used by vast combustion gas user at present, gas meter, flow meter manufacturer is in order to save cost, how to replace metal material with plastics, to save cost, the present gas meter, flow meter that uses, its gas outlet substantially all is to be made by engineering plastics, in actual use, the gas outlet that the user destroys gas meter, flow meter has appearred, common practices is to hole on the gas outlet inwall, make to enter the measuring apparatus of the interior combustion gas of gas meter, flow meter shell, but directly enter gas outlet, reach the purpose of gas gas leakage steathily without gas meter, flow meter.
Therefore the shortcoming of prior art is: the gas outlet of gas meter, flow meter is destroyed easily, causes by destroying gas meter, flow meter and steals gas.
The utility model content
The purpose of this utility model provides a kind of gas meter, flow meter that can anti-theft gas.
For achieving the above object, the utility model is explained a kind of anti-theft gas gas meter, flow meter, comprise shell body and metering movement, described metering movement is installed in described shell body inside, inlet end joint and outlet side joint are installed on the described shell body, described metering movement is provided with air intake opening and gas outlet, the air intake opening of described metering movement communicates with described shell body inside, joint bottom, described outlet side is connected with the gas outlet of gas outlet, the air intake opening of this gas outlet is connected with the gas outlet of described metering movement, its key is: be set with inner sleeve in the described gas outlet center pit, this inner sleeve top outward flanging becomes the gas outlet of toroidal and described gas outlet to fit.
Rock gas enters in the shell body internal cavities by the inlet end joint, when the user uses rock gas, rock gas enters the metering movement by the air intake opening of metering movement, be transported to by the gas outlet that is connected with metering movement gas outlet and be transferred to the outlet side joint, use for the combustion gas tool that is connected with escape pipe, the rock gas volume that its movement is crossed in the convection current of metering movement carries out accumulated counts, the gas outlet material of installing on this gas meter, flow meter is traditional engineering plastics, the inner sleeve that suit is made by the material of anti-destruction in the through hole of gas outlet middle part, inner sleeve is generally made by stainless steel, its anti-destruction, simple in structure, easy for installation, cost is little.The hydraucone shape that inner sleeve top outward flanging becomes and the gas outlet of gas outlet fit tightly, and cover the inside of gas outlet fully, effectively prevent the generation of gas gas leakage steathily.
Described gas outlet bottom is equipped with mount pad, has mounting hole on the described mount pad, and described mount pad bottom surface is positioned at the top of described gas outlet bottom surface, and described gas outlet top is an annular frustum, and the middle part of this annular frustum has annular groove.
The mount pad of gas outlet is installed on the metering movement by screw, gas outlet middle part through hole communicates with the gas outlet of metering movement, and gas outlet upper, annular frustum has annular groove, and rubber ring is installed on the annular groove, gas outlet top is connected with joint bottom, outlet side, and rubber ring plays the effect of sealing.
Remarkable result of the present utility model is: can prevent tax evasion gas, inner sleeve is simple in structure, and is easy for installation, and cost is little.
Description of drawings
Fig. 1 is a structural principle synoptic diagram of the present utility model;
Fig. 2 is the structural representation that the gas outlet of inner sleeve is housed;
Fig. 3 is the vertical view of gas outlet;
Fig. 4 is the A-A view of Fig. 3.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, anti-theft gas gas meter, flow meter, comprise shell body 1 and metering movement 2, described metering movement 2 is installed in described shell body 1 inside, inlet end joint 3 and outlet side joint 4 are installed on the described shell body 1, described metering movement 2 is provided with air intake opening and gas outlet, the air intake opening of described metering movement 2 communicates with described shell body 1 inside, joint 4 bottoms, described outlet side are connected with the gas outlet of gas outlet 5, the air intake opening of this gas outlet 5 is connected with the gas outlet of described metering movement 2, be set with the inner sleeve 6 that stainless steel material is made in described gas outlet 5 center pits, these inner sleeve 6 top outward flangings become the gas outlet of toroidal and gas outlet 5 to fit, inner sleeve 6 tops cover the top of gas outlet 5 fully, both closely cooperate, realize that inner sleeve 6 covers the inside of gas outlet 5 fully, prevent to destroy gas outlet 5 and steal gas, perhaps owing to reason breakages such as gas outlet 5 wears out are leaked gas.
Shown in Fig. 2 to 4, gas outlet 5 bottoms are equipped with mount pad 7, have four mounting holes 8 on the described mount pad 7, the level height of described mount pad 7 bottom surfaces is higher than the level height of described gas outlet 5 bottom surfaces, described gas outlet 5 tops are an annular frustum 9, and the middle part of this annular frustum 9 has annular groove 10; Be installed on the metering movement 2 by the mount pad 7 of screw gas outlet 5, gas outlet 5 middle part through holes communicate with the gas outlet of metering movement 2, gas outlet 5 upper, annular frustums 9 have annular groove 10, on the annular groove rubber ring can be installed, play the effect of sealing, gas outlet 5 tops are connected with outlet side joint 4 bottoms.
