Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further details.
As illustrated in fig. 1 and 2, the assembling pipe joint of the fast demountable that the application provides, including tubing joinder 1, described tubing joinder 1 be respectively provided on two sides with gland 2, pipeline tapping bail wire 3, band platform wedging ring 4 and sealing ring 5, the two ends of described tubing joinder 1 are provided with tubing joinder screw thread 11 in the same direction, and the inside of described tubing joinder 1 is provided with two sealing surfaces 12；The sealing ring 5 of described tubing joinder 1 both sides is individually placed on two sealing surfaces 12 of tubing joinder 1, and the sealing ring 5 of both sides band platform wedging ring 4, pipeline tapping bail wire 3 and gland 2 with both sides respectively is linked in sequence；The lower end of described band platform wedging ring 4 is inserted the end head of tubing joinder 1 and is enclosed within pipeline, its inner face 41 contacts with sealing ring 5, outer face 42 offsets with the inner face 31 of pipeline tapping bail wire 3, and the outer face oblique 32 of opening bail wire contacts with the medial slope 21 of gland 2；Described gland 2 is connected with tubing joinder 1 by gland screw thread 22 and tubing joinder screw thread 11；Described pipeline tapping bail wire 3 is the ring body of opening retractable diameters.
The attachment means that the application provides, by the screw thread design in the same direction at tubing joinder 1 two ends, needs gland 2 to tighten in the same direction when mounted, it is ensured that pipeline tightens in the same direction, facilitates the Fast Installation of workman, improve work efficiency.
Pipeline tapping bail wire 3 described herein is the ring body of opening retractable diameters, it is preferable that opening thereon is and the parallel open axially becoming angle, and is provided with clamping screw thread 33 in inner side；Preferably, clamping screw thread 33 is multi-turn bastard screw thread or the many groups of parallel bastard lines becoming angle section to be triangle with axis；Pipeline tapping bail wire 3 in use can radially reduce diameter, and by clamping screw thread clamping pipeline, it is ensured that pipeline cannot be carried out moving axially and radial rotating.
It addition, in installation process, to keep the distance at least 1 times of sealing ring 5 line footpath between two end faces of two pipeline 8 joints of described tubing joinder 1 both sides, so could more easily change aging parts；Install for convenience, preferably, can set a locating ring 7 in tubing joinder 1, locating ring can make it can only pass in and out from the side of tubing joinder 1 by the boss of tubing joinder 1 is spacing, the width of locating ring is at least 1 times of sealing ring 5 line footpath, and corresponding structure is as shown in Figure 3.
Band platform wedging ring 4 outer face described herein can be plane form, it can also be the structure of band boss, or the shape being integrated with band boss outer face for its step 43, actual should during, can adjust the shape of pipeline tapping bail wire accordingly according to the structure of band platform wedging ring 4 outer face, Fig. 4 and Fig. 5 is wherein through low cost, two kinds of practical shapes of practical proof.
First two pipeline 8 joints are inserted respectively during specifically used by the attachment means that the application provides from the two ends of tubing joinder 1, if there being locating ring 7, then first locating ring is put on the boss of tubing joinder 1, and packing ring, sealing ring 5, band platform wedging ring 4, pipeline tapping bail wire 3 and gland 2 it is inserted in successively in both sides, it is inserted into pipeline, sealing ring 5 contacts with the sealing surface in tubing joinder 1, without locating ring, two pipelines the both ends of the surface in tubing joinder 1 need to keep the spacing in about 1.5 times of sealing ring 5 line footpaths；Gland 2 promotes pipeline tapping bail wire 3 to be axially moveable by gland medial slope 21 contact, and promotes the band platform wedging ring 4 being in contact with it to compress sealing ring 5 in tubing joinder 1 vertically, makes sealing ring 5 reach effectively and seals deformation.After the step 43 of band platform wedging ring 4 compresses with tubing joinder 1 outer face 13, the pipeline tapping bail wire 3 being in contact with it cannot continue to be axially moveable, diminish in the effect under shed gap of gland medial slope 21 extruding, radially reduce diameter, bastard screw thread clamping pipeline inside pipeline tapping bail wire 3, it is ensured that pipeline cannot be carried out moving axially and radial rotating；The gland 2 of pipeline both sides is homodromal.When after sealing ring 5 seal failure, unclamp gland 2, then pipeline tapping bail wire 3, band platform wedging ring 4, sealing ring 5 loses external force, recover deformation, can be axially moveable on pipeline, tubing joinder 1 can on pipeline single-way moving vertically, the joint making two pipelines 8 removes, after taking out locating ring 7, then tubing joinder 1 can on pipeline way moving vertically, inefficacy sealing ring 5 is after two pipeline end faces keep pulling down replacing the spacing in about 1.5 times of sealing ring 5 line footpaths, put back to locating ring 7, Fast Installation completes, the replacing of potted component can be completed without the pipeline 8 on disassembling pipe and pipe fitting.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope of present disclosure; according to technical scheme and inventive concept equivalent or change in addition thereof, all should contain within protection scope of the present invention.
