Description
The utility model relates to the rapid pipeline connection set of a kind of suitable gas and liquid conducting pipes.It is widely used in every field such as hot-water heating installation, gas pipe line installation, chemical system piping erection and urban construction.
In existing piping erection, the assembling pipe joint kind of selecting for use is a lot, does not have two kinds but the Placement between connection set and steel pipe is outer.A kind of is to utilize electric welding that connection set and steel pipe are welded together; Another kind be in the connection set hole be assembled together after outer diameter of steel pipes is processed into the screw thread that matches simultaneously.There is following problem thus:
1, in the piping erection process, need steel pipe and connection set are welded together, so just need the several people to cooperate to carry out to weld again behind the centering.Its auxiliary time is longer, also need be equipped with electric welding machine, and the technical merit of welding worker is had relatively high expectations.In general, in the overall process of the intact connection set of every assembling, weld the used time to account for 40% of overall process;
2, in the installation process of plumbing pipe, need tube head is processed into pipe thread, this just needs special tools such as worktable, clamp device and band silk, and operator's labor intensity is very big, and the time that takies simultaneously is also longer;
3, the quick mounting joint of using now also needs before installation protruding tube head to be welded on the steel pipe, and the processing technology complexity of this joint, and manufacture cost is also very high.
The purpose of this utility model is exactly that a kind of rapid pipeline connection set that neither need weld and not need just pipeline to be linked together in the tube head machining screw will be provided.
The purpose of this utility model is achieved in that it is made up of connecting body, seal arrangement and hold down gag.By connecting body two pipelines being coupled together, matches with seal arrangement in the connecting body both sides, by the hold down gag in the seal arrangement outside connecting body and seal arrangement is fixed, and two pipelines are closely linked together.
Distinguishing feature of the present utility model is: utilize metal plastic deformation and rubber elasticity to be out of shape this feature, by choose reasonable to assembling pipe joint associated shape and each size, the pressure that utilization is produced in installation, seal arrangement and pipeline are closely linked, thereby reach the connection and the seal action of pipeline enclosure; It has saved and has overlapped the system screw thread or weld this two procedures in piping erection, thereby has reduced piping erection technology and supplementary equipment; The destruction that can make the top layer protective tissue of pipelines such as galvanized pipe not be subjected to smear metal and scaling loss; For the cast iron tube that is difficult for welding etc. has been created easy-to-install condition; Can provide by the specification condition of blanking in batch for some construction places.

Below in conjunction with accompanying drawing the utility model is further described:
The utility model can select following three kinds of assembling forms to realize according to the various conditions of pipeline.
Shown in Fig. 1-4, A kind rapid pipeline connection set is made of connecting body 1, seal arrangement (collar 3, seal ring 2), hold down gag (bolt 5, gland 4).Connecting body 1 is one and is enclosed within the cirque body that two-phase connects pipeline enclosure, which is provided with the threaded shank hole 15 of several and parallel to an axis, and the connecting body internal surface is provided with step 17 that matches with O RunddichtringO 2 and the step 16 that matches with collar 3.Seal ring 2 is O type rubber seal that are enclosed within on the pipeline 14 and match with pipeline.Collar 3 is enclosed within on the pipeline 14, its outer surface is provided with the conical surface 20 that matches with gland 4 and is convenient to a circle groove 19 of plastic deformation, and on collar 3, having six sulculuses 18 that perpendicular collar is axial, the mating reaction of the conical surface by gland 4 and the collar conical surface etc. makes collar produce radial deformation.Gland 4 is enclosed within on the pipeline 14, which is provided with the bolt hole 21 of several and its parallel to an axis, and the gland internal surface is provided with the conical surface 22 that matches with the conical surface 20 in the collar 3.
By bolt 5 gland 4, collar 3, seal ring 2 and connecting body 1 are tightened together, with spanner gland 4 is shifted near abreast to connecting body 1, fastening along with bolt, collar 3 produces and moves axially, compressing O RunddichtringO produces resiliently deformable, seal up the leak of pipeline enclosure, reach sealing and fastening effect.
Shown in Fig. 5-8, B kind rapid pipeline connection set is made of connecting body 6, seal arrangement (collar 7), hold down gag (bolt 9, nut 28, gland 8).Connecting body 6 internal surfaces are provided with the conical surface 23.One end of collar 7 is provided with the step 25 of being convenient to plastic deformation, and outer surface is provided with a circle groove 24.Gland 8 is provided with the bolt hole 26 with its parallel to an axis, and its internal surface is provided with the step 27 that matches with collar 7.Bolt 9 closely links together two pipelines with making connecting body 6 and collar 7 cooperating of nut 28.
The installation method of this kind rapid pipeline connection set is similar to the A kind, difference be it sealing and fastening be to be provided with the plastic deformation that step one end pressurized produces by collar to form.Because plastic deformation of metal is limited, the stretchability of metal is relatively poor simultaneously, and it is higher that it requires the outside dimension precision and the degree of finish of pipeline for this reason.
Shown in Fig. 9-12, C kind rapid pipeline connection set is made of connecting body 10, seal arrangement (collar 12, seal ring 11), hold down gag (nut 13).The outer surface two ends of connecting body 10 are provided with screw thread 29, and internal surface is provided with the step 30,31 that matches with seal ring 11, collar 12.Have six vertical its axial sulculuses 34 on the collar 12, outer surface is provided with the conical surface 33 that matches with nut 13 and is convenient to a circle groove 32 of plastic deformation.The internal surface of nut 13 is provided with the conical surface 35 that matches with collar 12 and the screw thread 36 that matches with connecting body 10.
No matter this kind device is all close with the A kind on textural and characteristics.Different is that this device is applicable to the pipe-line system installation that caliber is less.
The example test:
Test selects for use ZS-2 t shore testing machine to carry out.With the 50# antiwear hydraulic oil is work fluid.By test specimen is to carry out after installing by the form fit dimensioned of the part shown in Fig. 5-8 and Fig. 9-12.Wherein the employed at the trial steel pipe of B kind rapid pipeline connection set is that external diameter is the seamless steel pipe of φ 90, and the external diameter roundness tolerance of this steel pipe is less, and degree of finish is higher.C kind rapid pipeline connection set selects 1 at the trial for use " zinc-plated water gas conveying steel pipe, the circularity of this outer diameter of steel pipes and degree of finish are all undesirable, and the purpose of selecting for use just is to check its adaptability.Test result such as following table:
B kind connection set pressure test table
Whether the withstand voltage numerical value dwell time leaks
2MPa did not have leakage in 10 minutes
4MPa did not have leakage in 10 minutes
6MPa did not have leakage in 10 minutes
8MPa leaked in 1 minute
C kind connection set pressure test table
Whether the withstand voltage numerical value dwell time leaks
2MPa did not have leakage in 10 minutes
4MPa did not have leakage in 10 minutes
6MPa did not have leakage in 10 minutes
8MPa did not have leakage in 10 minutes
To their pressure test, be the important indicator that can this kind of check connection set be used.This test result is that the highest voltage endurance capability can reach 6MPa, and the voltage endurance capability that proves this connection set thus and possessed can be applied in the water gas conveyance conduit.
