Abstract
The invention relates to a sealing connection method for thin-wall stainless pipe. The pipe is made up of pipe body and sealing ring. The pipe body and the pipe are connected together with glue. At the same time, on the internal side of the connecting cone surface is arranged with sealing ring which has self sealing function under pressure of fluid, resists the boiled water from immersing the glue layer. The method can make stainless steel pipe applied to transmit each kind of fluid media, it also includes boiled water pipe.
Description
(1) technical field:
The present invention relates to thin wall stainless steel pipeline seal adhesive connecting method, be applicable to the thin-walled stainless steel tube of carrying various fluids.
(2) background technique:
Since thin-walled stainless steel tube came out, the pipe fitting that adopts on the engineering mainly contained following three kinds.A kind of is the MOLCO clamp-press type pipe, and China and the U.S., Britain, Germany, Japan and other countries have all been formulated corresponding industry standard.Its major defect is: the rubber seal that (1) seals is in the pipe fitting external port, owing to be exposed in the air, easily produces aging.(2) pipe fitting can't be dismantled.Another kind is the spigot and socket type weld-end fittings, and its major defect is: (1) installs trouble, and each interface all need weld.(2) pipe fitting can't be dismantled.Another is a quick-acting pipe spare, though its structure is not quite similar, common drawback is a complex structure, and cost is too high.In order to overcome the above-mentioned deficiency of prior art, in the patent application of number of patent application 00130741.X, the bonding connection method of thin-walled stainless steel tube has been proposed.Though its cost is low, and is easy for installation, can dismantle, on probation showing, to the pipeline of long-term delivery hot water, owing to have hot water " etch " effect to glue-line, so do not try out in hot water pipeline.
(3) summary of the invention:
The objective of the invention is to provide a kind of thin wall stainless steel pipeline seal adhesive connecting method, states the patent application deficiency to fill, and enables to be applicable to hot water pipeline.
The object of the present invention is achieved like this: in a pipe fitting of being made up of pipe fitting and seal ring, the outer end of pipe fitting joint is conical.Conjointly be provided with an annular groove with this taper shape the inner, the seal ring that has self-sealing function under hydrodynamic pressure is housed in the groove.The outer end of pipe joint is cylindrical, passes seal ring and also closely cooperates with it, and its inner has the outer little interior big taper shape with the identical tapering of pipe fitting, forms the conical surface by adhesive between the two and connects.Seal ring can be made annular groove thereon one, and the height on edge is less than the shape of outer in the groove.Fluid of this height difference formation can enter the slit in the groove.Thereby under fluid pressure action, the interior edge of seal ring closely surrounds pipe, produces self sealing action.Seal ring also can adopt the water-expansible rubber manufacturing, for water pipe, because imbibition also can produce self sealing action.
Like this,, stoped " etch " of hot water, improved the hot water resistance energy of bonded joint, enabled to be applicable to hot water pipeline because the self sealing action of seal ring separates bonding plane and water.Adopt the bonding head of envelope of this seal adhesive connecting method, be applicable to and being connected of tubing.
For with the piping attachment that has pipe thread (as valve, water meter etc.) between be connected, then the pipe fitting the other end is processed into corresponding pipe thread.Thereby constitute the envelope bonding head of an end for being connected with tubing, the other end is the wire connection joint that is connected with piping attachment.
In order in pipeline, to constitute the loose joint structure, be processed with outside thread at pipe fitting one end, the nut that has an internal thread passes the loose joint body and matches with outside thread on the pipe fitting.Seal ring between pipe fitting and loose joint body is a hollow structure, and edge has the enterable slit of fluid in it between a side edge.Such ring structure can seal pipe under hydrodynamic pressure, the internal and external threads face that also can be tightly connected simultaneously.Wherein the external end of loose joint also can be processed into pipe thread, is the bonding head of envelope that is connected with pipe thereby form pipe fitting one end, and the other end is the wire connection joint that is connected with piping attachment, connects by nut between the two ends again, becomes easy-off loose joint joint.
The invention will be further described below by drawings and Examples.
(4) description of drawings:
Fig. 1 is the sectional arrangement drawing of the bonding head of envelope.
Among the figure: 1, pipe fitting 2, seal ring 3, adhesive 4, pipe
Fig. 2 is the union sectional arrangement drawing.
Among the figure: 1, pipe fitting 2, seal ring 3, adhesive
4, pipe 5, nut 6, loose joint body
(5) embodiment:
Pipe fitting (1), nut (5) and loose joint body (6) all adopt with pipe (4) with the material stainless steel, make by precision casting.Seal ring (2) can adopt the manufacturing of silicone rubber elastomeric material.Adhesive (3) can adopt second generation acrylate adhesive.Pipe (4) can adopt Spinning pipe cutter (number of patent application 200410000558.6) to cut, and adopts pipe end shrink mouth device (number of patent application 200420049026.7) that pipe end is processed.
