Abstract
The utility model relates to an elastic sealed composite pipeline connector which is formed by the way that notches on both ends of an inner through hole are provided with pipe sleeves for step type grooves, platform troughs in pipe openings on both ends of each pipe sleeve are respectively connected with an elastic sealing ring and a check ring, and elastic snap rings are inlaid in annular grooves of the pipe openings. The utility model has the advantages of novel structure, reasonable design, easy processing, high compressive strength, good seal performance and convenient use, and is widely suitable for the connection of plastic pipes with large calibers or the connection of plastic pipes with metal pipes. The utility model is a novel pipeline connector.
Description
Technical field
The utility model relates to a kind of joiner of plastic pipe.
Background technique
Along with the extensive use of plastic pipe, the also continuous development and progress of its used plastic pipe joiner.In known technology, existing pipeline connects the main methods such as pipe box scyewed joint, flange connection, enlarging grafting, the welding of plastics counterpart, the molten weldering of bonding electricity that adopt, but it is low all to exist joint strength, and installation and processing is loaded down with trivial details, time-consuming, shortcomings such as sealability is relatively poor, particularly the two ends jointing processing effort difficulty of large-bore plastics tubing is big, the huge heaviness of process equipment, cost height, and inefficiency brings inconvenience to use.
Summary of the invention
The purpose of this utility model provides a kind of improved plastic pipe joiner, makes its novel structure, and processing is equipped simple and easy, time saving and energy saving, and good airproof performance is particularly useful for the joiner of large-bore plastics pipeline.
For achieving the above object, the technological scheme that the utility model is taked is: adopt the pipe box that is shaped on stepped recesses at the two ends mouth of pipe, the interior platform trough load elastic seal ring and the back-up ring of the pipe box mouth of pipe, embedded the shooting property snap ring of the ring groove of the mouth of pipe, the composite plastic pipeline joiner of the elastic packing that consists of.During use, the tubing jointing that need are connected grinds groove, earlier be enclosed within snap ring, back-up ring and O-ring seal on the tubing successively, insert two tubing in the pipe box relatively again, afterwards O-ring seal and back-up ring load interior platform trough to the pipe box two ends mouth of pipe, again snap ring is installed on respectively in the ring groove of the pipe box two ends mouth of pipe at last, has just realized the connection of pipe fitting two plastic tubes.
Because the composite plastic joiner structure of elastic packing has been adopted in the utility model design.The contrast prior art, it has novel structure, and is reasonable in design, process simple and easy, connect quick, compressive strength height, advantage such as airtight performance is good, easy to use.It is applicable to the connection of plastic tubes such as heavy caliber (is more than 300～630mm reaches as diameter) polyethylene, polypropylene, PVC, also is applicable to connecting of plastic tube and metal tube, also can be applicable to the repairing leak stopping connection of old pipeline etc.The pipeline that can be widely used in industries such as agricultural water-saving irrigation, ejectment water conservancy project journey, urban construction water supply project and industrial and mining enterprise connects engineering, is a kind of novel pipeline joiner.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model embodiment concrete structure sectional view.
Reference character: 1 pipe box, 2 liners, 3 elastic seal rings, 4 back-up rings, 5 snap rings, 6 tubing.
Embodiment
Embodiment as shown in Figure 1, the utility model is the pipe box 1 that is shaped on the step type groove by the inner via hole two ends mouth of pipe, the interior platform trough of the pipe box 1 two ends mouth of pipe is embedded the shooting property snap ring 5 of ring groove of load O-ring seal 3 and back-up ring 4, the mouth of pipe respectively, the composite plastic pipeline joiner of the elastic packing that consists of.
Pipe box 1 endoporus of the utility model pipe jointer and back-up ring 4 cooperates and supporting tubing, and be even to the side pressure of O-ring seal 3, it can not flattened and press partially, makes it the spring-back force that keeping good, the sealability of protection cushion rubber; Form a variable annular groove between pipe box 1 endoporus step and the back-up ring 4, make seal ring 3 form a seal band more freely.Also played the effect of expansion joint.
The utility model is joined the pipe box 1 that connects and is the high duty metal pipe box, and its outer surface carries out plastic-blasting to be handled, and inwall is attached with liner 2 by blowing, can play good antiseptic and rustproof effect; Pipe box 1 also can be used the plastic pipe sleeve of polyethylene, polypropylene, PVC etc., so just omits liner 2.
Claims (3)
1, a kind of composite plastic pipeline joiner of elastic packing, it comprises pipe box, it is characterized in that also comprising elastic seal ring (3), back-up ring (4) and snap ring (5), pipe box is the pipe box (1) that the inner via hole two ends mouth of pipe is shaped on the step type groove, embedded the shooting property snap ring of ring groove (5) of the interior platform trough difference load elastic seal ring (3) of pipe box (1) the two ends mouth of pipe and back-up ring (4), the mouth of pipe.
2, pipe coupler according to claim 1 is characterized in that pipe box (1) is metal pipe box or plastic pipe sleeve.
3, pipe coupler according to claim 2 is characterized in that being shaped in the metal pipe box (1) liner (2).
