Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
In the present embodiment, the concrete restrictive condition of institute's connecting tube by: connected two pipelines, but wherein have at least the end of a pipeline that the fastening screw thread of socket is arranged, and have in two pipelines one the pipe removable.
To shown in Figure 6, comprise connecting sleeve 1, seal ring 2, lining 3, retaining ring 4 like Fig. 1 in the utility model assembling pipe joint.
During assembling; Move the end of a pipeline, enlarge the distance between two pipes, 5,6 ends, in pipeline 6 ends; Suit retaining ring 4, lining 3, seal ring 2, connecting sleeve 1 successively; There is an end of screw thread 501 to dock on two pipelines, 5,6 ends of aliging, an end that connecting sleeve 1 is provided with screw thread 101 and pipe end 5 and tightens, make pipeline 5 and connecting sleeve 1 be tightly connected fixing.
Subsequently; On pipeline 6; On the position of connecting sleeve 1 the other end conical section 102, screw thread 103, be set with seal ring 2, lining 3 by the opposite direction of previous suit, tighten lining 3, lining 3 inboard end 304 inside pushing tow seal rings 2; Make on seal ring 2 internal surfaces 201, the outer surface fitting surface 202 respectively with pipeline 6 cylindricals, connecting sleeve 102 airtight joining of 1 upper conical section, thereby pipeline 6 and connecting sleeve 1 are tightly connected.
At last; Suit and tighten retaining ring 4 on the outboard end outside thread 305 of lining 3; The conical surface 303 on the conical surface 402 extruding linings 3 on the retaining ring 4 makes that lining 3 is outer then to be held 302 radial contraction and be locked with the pipeline that is arranged in hole in it 6, and accomplishes thus being connected pipeline 5 and pipeline 6.
In order to make seal ring 2 and to be arranged in the pipeline external surface in hole in it and 102 reliable airtight the joining of conical section in 1 li hole of connecting sleeve; As shown in Figure 7; Also be spaced several bulge loops 204 in the seal ring 2 on the sidewall of hole vertically, be spaced several bulge loops 203 on the fitting surface 202 on seal ring 2 outer surfaces equally vertically.
In the present embodiment, the concrete restrictive condition of institute's connecting tube by: connected two pipelines, wherein have at least a tube end to have and can be used for the fastening screw thread of socket, and the ends of tubes relative fixed, can not be moved.
As scheme Fig. 8, shown in 9, connecting sleeve by about two sections 8A, 8B butt joint form, left side section 8A docks with screw thread 805 through screw thread 804 with right section 8B and is connected.
During assembling; Inspection two pipes 5,6 tip spacings are from being not less than lining 3, left side section 8A, right section 8B axial length; On another pipeline 6 relative with pipe 5 screw threads 501; Suit retaining ring 4, lining 3, seal ring 2, left side section 8A, right section 8B successively dock left side section 8A after adding sealing material on the right section 8B screw thread 805 then and tighten with a right side section 8B; Then, with the screw thread 801 of right section 8B one end with manage screw thread 501 on 5 and dock and tighten.At last, when the step of pressing the foregoing description 1 is installed seal ring 2, lining 3 by the opposite direction of previous suit on pipeline 6, retaining ring 4, accomplish remaining installation process.
