Then the gas inlet of a pair of of connecting pin insertion gas meter, flow meter is detected with gas exit, be usually all in existing detection process
It is directly sleeved on connecting pin, but so often sealed not perfect by a sealing ring.
Utility model content
Problem to be solved in the utility model is to provide a kind of combustion gas for the above-mentioned deficiency in the presence of the prior art
Gas leakage when table air-leakage test sealing mechanism prevents from detecting.
To achieve the above object, the utility model employs following technical solution：A kind of gas meter, flow meter air-leakage test is close
Sealing mechanism, it is characterised in that：Including connector, the first sealing ring, the second sealing ring, gasket and fixing piece, the connector bag
Connector body and the protrusion being arranged on the left of the connector body are included, first sealing ring is sleeved in the protrusion, institute
Stating has recess on the right side of connector body, and second sealing ring is overlayed in the recess, the fixing piece tighten through
Second sealing ring, connector body, the first sealing ring and gasket the airtight detector connecting pin on.
Further, the gasket is equipped with a circle and is recessed, and the protrusion is stuck in the recess.
Compared with the prior art, the utility model has the advantages that：The utility model passes through in the connector
Second sealing ring is adjacent on the right side of body, first sealing on set in the protrusion on the left of the connector body
Second sealing ring, connector and first sealing ring, are then sleeved on the connecting pin, then again by institute by circle together
It states gasket to be sleeved on the connecting pin, be tightened finally by the fixing piece at the screw thread of the connecting pin, the fixing piece
For nut, so described second sealing ring, connector and first sealing ring would not come off from the connecting pin, combustion gas
The gas inlet of table, which is sleeved on gas exit on the connecting pin, covers the upper fitting, the first sealing ring, the second sealing ring, pad
On piece and fixing piece, then from pass on left introduce gas meter, flow meter fuel gas inlet connector and gas outlet connector be sequentially sleeved in it is described
Fixing piece, gasket, the first sealing ring, connector, the second sealing ring and the second sealing ring；When gas meter, flow meter fuel gas inlet connector with
After gas outlet connector is inserted in, the fuel gas inlet of sealed connecting component body and gas meter, flow meter connects after being squeezed by first sealing ring
Head gas outlet connector between gap, by second sealing ring in recess due to it is described recess indent effect make
Second sealing ring seals the gap between the connecting pin of airtight detector and connector, so as to fulfill double-layer seal, normally
In use, the connecting pin is vertical, the gas inlet of gas meter, flow meter is with being directed at the connecting pin on gas exit vertical direction.
Part is illustrated to embody by the further advantage, target and feature of the utility model by following, and part will also pass through
Research and practice to the utility model and be understood by the person skilled in the art.
Description of the drawings
Fig. 1 is a kind of gas meter, flow meter air-leakage test sealing mechanism structure diagram of the utility model.
Specific embodiment
In order to which the technological means, creation characteristic, the reached purpose that realize the utility model more understand and are easy to acting on
Understand, the utility model is further elaborated with reference to the accompanying drawings and detailed description：
The utility model proposes a kind of gas meter, flow meter air-leakage test sealing mechanism, including connector 1, the first sealing ring 2,
Second sealing ring 3, gasket 4 and fixing piece, the connector 1 include connector body and are arranged on the left of the connector body
Protrusion 11, first sealing ring 2 is sleeved on described raised 11, has recess on the right side of the connector body, described second
Sealing ring 3 is overlayed in the recess, and the fixing piece is tightened through second sealing ring 3, connector body, first close
On the connecting pin 5 of the airtight detector of seal 2 and gasket 4.
The utility model on the right side of the connector body by being adjacent to second sealing ring, in the connector body
First sealing ring is put in the protrusion in left side, then by second sealing ring, connector and first sealing
Circle is sleeved on together on the connecting pin, and then the gasket is sleeved on the connecting pin again, is turned round finally by the fixing piece
Tightly at the screw thread of the connecting pin, the fixing piece is nut, so described second sealing ring, connector and described first close
Seal would not come off from the connecting pin, and gas inlet and the gas exit of gas meter, flow meter are sleeved on the connecting pin on set
On the fitting, the first sealing ring, the second sealing ring, gasket and fixing piece, then from introducing gas meter, flow meter is passed on left by combustion gas
Inlet union and gas outlet connector be sequentially sleeved in the fixing piece, gasket, the first sealing ring, connector, the second sealing ring and
Second sealing ring；After the fuel gas inlet connector of gas meter, flow meter is inserted in gas outlet connector, squeezed by first sealing ring
Gap between sealed connecting component body and the fuel gas inlet connector of gas meter, flow meter and gas outlet connector afterwards, it is close by described second
Seal is in recess since the effect of the recess indent makes connecting pin and the company of the airtight detector of the second sealing ring sealing
Gap between fitting, so as to fulfill double-layer seal, during normal use, the connecting pin is vertical, the gas inlet of gas meter, flow meter with
The connecting pin is directed on gas exit vertical direction.
As specific embodiment, the connecting pin 5 is equipped with screw thread 51, and the fixing piece is nut, is tightened by nut
On the screw thread 51.
