Description
Technical field
The utility model relates to pipe joint field, is specifically related to a kind of combustion gas polyethylene pipe.
Background technique
The fittings body position of existing combustion gas polyethylene pipe generally adopts screw-thread fit, and sealability is poor, and fittings body position there will be gas leak phenomenon, is badly in need of improving.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of combustion gas polyethylene pipe, good seal performance, there will not be gas leak phenomenon.
For achieving the above object, the technical solution of the utility model is: combustion gas polyethylene pipe, comprise first fittings body and the second fittings body of working in coordination and connecting, described first fittings body front end is provided with reducing pipe, first fittings body and reducing pipe intersection are provided with outward extending ora terminalis, described ora terminalis comprises abutting part and pressure contact portion, flange is provided with in the middle part of described reducing pipe outer wall, described flange inner is provided with seal ring, sealing gasket and jump ring is provided with between flange outer sides and abutting part, described jump ring is between flange outer sides and sealing gasket, described second fittings body front end is provided with expansion tube, described expansion tube inwall is provided with step surface, described step surface both sides form large-diameter pipe and small diameter tube respectively, step surface is connected to flange inner, the internal diameter of described small diameter tube and the external diameter of reducing pipe match, described large-diameter pipe inwall is provided with groove, large-diameter pipe end props up abutting part, the external diameter of the internal diameter of large-diameter pipe and flange and sealing gasket matches, the external diameter of large-diameter pipe and the diameter compatible of pressure contact portion, described jump ring snaps in groove.
The diameter of described reducing pipe reduces gradually from the first fittings body front end.
The diameter of described expansion tube expands gradually from the second fittings body front end.
The beneficial effects of the utility model: good seal performance, there will not be gas leak phenomenon and easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged view at A place in Fig. 1.
In figure: the first fittings body 1, reducing pipe 11, ora terminalis 12, flange 13, abutting part 14, pressure contact portion 15, second fittings body 2, expansion tube 21, large-diameter pipe 22, small diameter tube 23, groove 24, step surface 25, seal ring 3, jump ring 4, sealing gasket 5.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, combustion gas polyethylene pipe, comprise first fittings body 1 and second fittings body 2 of working in coordination and connecting, described first fittings body 1 front end is provided with reducing pipe 11, first fittings body 1 is provided with outward extending ora terminalis 12 with reducing pipe 11 intersection, described ora terminalis 12 comprises abutting part 14 and pressure contact portion 15, flange 13 is provided with in the middle part of described reducing pipe 11 outer wall, seal ring 3 is provided with inside described flange 13, sealing circle 3 forms first sealing, sealing gasket 5 and jump ring 4 is provided with outside flange 13 and between abutting part 14, sealing pad 5 forms second sealing, described jump ring 4 is outside flange 13 and between sealing gasket 5, described second fittings body 2 front end is provided with expansion tube 21, described expansion tube 21 inwall is provided with step surface 25, described step surface 25 both sides form large-diameter pipe 22 and small diameter tube 23 respectively, step surface 25 is connected to inside flange 13, the internal diameter of described small diameter tube 23 and the external diameter of reducing pipe 11 match, described large-diameter pipe 22 inwall is provided with groove 24, large-diameter pipe 22 end props up abutting part 14, the internal diameter of large-diameter pipe 22 and the external diameter of flange 13 and sealing gasket 5 match, the external diameter of large-diameter pipe 22 and the diameter compatible of pressure contact portion 15, described jump ring 4 snaps in groove 24.
The diameter of described reducing pipe 11 reduces gradually from the first fittings body 1 front end.
The diameter of described expansion tube 21 expands gradually from the second fittings body 2 front end.
The expansion tube 21 of the second fittings body 2 only need insert in the reducing pipe 11 of the first fittings body 1 when installing by the utility model, jump ring 4 shrinks under the inwall compressing of large-diameter pipe 22, until large-diameter pipe 22 end props up abutting part 14, now step surface 25 is connected on the seal ring 3 inside flange 13, jump ring 4 then recovers resiliently deformable and falls in the groove 24 of large-diameter pipe 22, good seal performance, there will not be gas leak phenomenon to install more simultaneously.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
