The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As shown in Figure 1 to Figure 3: present embodiment discloses a kind of natural gas line connectors with gas leakage detection, including pipeline
One 1, the end of pipeline 22, sealing clamp 3, interconnecting piece 4 and pressure sensor 5, pipeline 1 is equipped with one end face 12 of pipeline, pipeline
One end face, 12 end is equipped with facing groove 121, and the end of pipeline 22 is equipped with pipeline biend 21, the end of pipeline biend 21
Equipped with head face hump 211, the side of pipeline 1 and pipeline 22 is equipped with wedge-shaped protrusion 23, and sealing clamp 3 is equipped with sealing clamp
Internal projection 31, sealing clamp flange face 32 and sealing clamp groove 33, pressure sensor 5 are set to inside interconnecting piece 4, interconnecting piece
4 are equipped with interconnecting piece ring flange 41 and interconnecting piece protrusion 42, when pipeline 1 is connect with pipeline 22,121 connecting pin of facing groove
Face protrusion 211, sealing clamp 3 pass through 31 connecting pipe of sealing clamp internal projection, one end face 12 and pipeline biend 21, interconnecting piece 4
Sealing clamp flange face 32 is connected by interconnecting piece ring flange 41, interconnecting piece 4 is also connected with wedge-shaped protrusion 23, and interconnecting piece protrusion 42 connects
Sealing clamp groove 33 is connect, pressure sensor 5 passes through interconnecting piece 4 by conducting wire.
It is close when preventing pressure larger in order to further enhance sealing clamp 3 for the leakproofness of pipeline 1 and pipeline 22
Envelope clip internal projection 31 deforms, and is preferably equipped with one protrusion 11 of pipeline in pipeline 1, and pipeline 22 is convex equipped with pipeline two
22 are played, one protrusion 11 of pipeline is all connected with sealing clamp internal projection 31 with two protrusion 22 of pipeline, is used for sealing clamp internal projection 31
More closely extrusion pipe biend 21 and pipeline biend 21.
For lift-off seal performance, facing groove 121 and head face hump 211 there are two, the effect of dual-seal can be played
Fruit.
It is bolted between the interconnecting piece ring flange 41 and sealing clamp flange face 32 of the present embodiment.
Sealing clamp 3 has two parts, and the two is symmetrical with joint face, when in use, 3 phase of two-part sealing clamp interconnects
