Abstract
The utility model discloses an all pipeline loose jointed overlapped pipe connection, which comprises a body. The utility model is characterized in that the terminal port of the body inner wall is in the shape of a step-like external cone. The external wall of the body is provided with a boss and a gland, one end of which corresponds with the body and the other end is in the shape of a cylinder inner cone. A locking cap whose inner wall has a boss is sheathed around the periphery of the body and the gland boss. A cup-shaped sealing ring, a plain cushion and a shedding lock ring are arranged in sequence between the terminal port of the body and the inside wall of the gland. The utility model has the advantages of wide application, easy installation, high work efficiency, small labour strength, convenient maintenance, etc. The utility model is in particular suitable for the temporal installation and maintenance and dismount of the water and the air route.
Description
The utility model relates to the new tube joint that pipelines such as being used for tap water, heating installation connects.
The pipe joint that uses in pipeline installation and maintenance process at present need manually be pulled the system screw thread, and labor intensity is big, and installation efficiency is low, when especially keeping in repair, and very inconvenience, expense height.
Task of the present utility model is: design a kind of pipeline that is directly used in and install, promptly need not pull the system screw thread on tube outer wall, and be beneficial to the raising installation efficiency, full pipeline loose joint overlapping pipe joint easy to maintenance.
Full pipeline loose joint overlapping pipe joint provided by the utility model, it includes main body, it is characterized in that: it is step-like that the main body inner wall port is outer cone, outer wall is provided with several boss, also having one one end and the other end corresponding with main body outer wall boss is the gland of the interior taper of cylinder, on the periphery of main body boss and gland boss, be with an inwall convex platform number and main body and the corresponding locking cap of gland boss number, between main body inner port place and gland inwall, be disposed with the bowl ring that inwall is the cylinder table scalariform, plain cushion and outer wall are the opening of screw thread tooth retainer on the coniform inwall.
The utlity model has following advantage: it is widely applicable, is specially adapted to provisional water, air pipe I﹠M, and have dismounting, simple installation and easily go, the work efficiency height, labor intensity is little, advantages such as maintenance facility.
Fig. 1 is the assembly structure schematic representation of the full pipeline loose joint of the utility model overlapping pipe joint.
Fig. 2 is that the locking cap A of the full pipeline loose joint of the utility model overlapping pipe joint is to view.
Fig. 3 is the sectional view of the bowl ring of the full pipeline loose joint of the utility model overlapping pipe joint.
Fig. 4 is the partial enlarged drawing of the opening retainer of the full pipeline loose joint of the utility model overlapping pipe joint.
To describe embodiment in detail in conjunction with above accompanying drawing.
Full pipeline loose joint overlapping pipe joint as shown in the figure, its critical piece comprises main body 1, gland 2, bowl ring 3, plain washer 4, opening retainer 5 and locking cap 6.Main body 1 inwall is cylindric, and its port is outer tubaeform circular cone scalariform, and several boss are arranged on the middle outer wall.Outer wall one end of gland 2 is provided with and corresponding several boss of main body boss, and it is coniform that inwall is.Seal ring 3 is shaped as bowl-type, and inwall is the cylinder table scalariform.Be coniform outside opening retainer 5 is shaped as, inwall is the worm tooth dentation.Between gland 2 inwalls and main body 1 inner port, be disposed with bowl ring 3, plain washer 4 and opening retainer 5, be with a locking cap 6 at main body 1 outer wall boss and gland 2 outer wall boss peripheries.Locking cap 6 one end inwalls are provided with several boss that match with main body 1 boss, gland 2 boss.In pipeline installation or maintenance process, earlier locking cap is enclosed within on gland 2 outer walls, then with gland 2, opening retainer 5, plain washer 4 penetrates on the outer wall of pipe 7 successively, pipe 7 terminations are inserted in the bowl ring 3, make plain washer 4, opening retainer 5 is close to bowl ring 3 and is real with the conical surface top of main body 1 termination, move axially gland 2 and locking cap 6, make of the outer wall reach of the inwall of gland 2 along main body 1 termination, gland 2 boss are corresponding with main body 1 boss, at last, rotation locking cap 6, it is interior and overlapping with the boss in the locking cap 6 to make main body 1 boss and gland 2 boss all be in locking cap 6, makes locking cap 6 that main body 1 is fixing with gland 2.Because the effect of axial pressure, the conical surface of gland 2 inwalls moves along the outer wall inclined-plane of opening retainer 5, compressing opening retainer 5 is held pipe tightly, meanwhile, opening retainer 5 promotes plain washer 4 even stressed extruding bowl rings 3, make its lateral expansion, seal, reach the purpose of connecting pipeline.
