The pipe connecting piece is simple to construct and convenient to operate, can save pipe cost and mounting time and cost, has strong drawing resistance, reliable connection, good sealing, good ageing resistance, and is particularly applicable to the connection of thin-wall stainless steel pipes in water supply systems and gas systems.
Description
Technical field
The utility model relates to pipeline and connects, and relates in particular to a kind of card and presses the bonded pipe joint of screw thread.
Background technique
At present, the Placement between existing stainless steel thin-wall tubing has following several: have plenty of and will between link and stainless steel thin-wall tubing, adopt welding type to be connected.This welding type Placement, construction trouble, scene must make electricity consumption, the poor chromium phenomenon of the high easily appearance of position temperature of its welding, solution treatment can not be carried out again in scene, and welding part is got rusty easily.And this welding connecting mode cost is higher; Have plenty of and seal ring is set in link and causes link and the plastic deformation of pipe fitting oral area to complete being connected between link and stainless steel thin-wall tubing by extruding.This Placement seal ring used is nitrile rubber seal ring, and its weatherability and rebound elasticity are all poor, seals easily agingly, and time one is long probably causes seepage, cannot guarantee that pipe-line system is long-term to occur without leaking; Also have plenty of and adopt simple bonding way, this mode is that the attachment hole of link is made to internal taper hole, the connection mouth of stainless steel pipe is made to outer cone mouth simultaneously, again sealant is spread upon respectively in the internal taper hole of link and on the surface of the outer cone mouth of stainless steel pipe, finally the outer cone mouth of stainless steel pipe is inserted in the internal taper hole of link, realized their connection.Although this Placement has solved the problem of aging of seal ring, the tension pull out force between them is also not ideal, and join strength is not so good as two kinds of modes above.
Model utility content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, and provides a kind of card to press the bonded pipe joint of screw thread, solves in current technology pipeline junction sealing bad, the problem that anti-pulling is poor.
For solving above technical problem, the technical solution of the utility model is:
A kind of card is pressed the bonded pipe joint of screw thread, include connecting body, adhesive layer and be connected tubing, it is characterized in that, the pipe fitting internal diameter of connecting body is than the large 0.2mm～1.0mm of the external diameter that is connected tubing, the pipe fitting inner wall coating adhesive adhesion coating of connecting body, being connected tubing is inserted in connecting body, be pressed into pressing section by blocking compression mould by connecting body and being connected tubing intersection card, make connecting body inwall and be connected tubing outer wall to fit tightly, pressing section part is thread section, and the two ends of thread section or one end are suppressed with anticreep section.Utilize card compression mould to impose compacting to the connection end position of connecting body, the cylindrical that makes the connection end position of connecting body produce plastic deformation and be connected tubing and engage and be riveted together, also be suppressed with anticreep section in riveted joint place, thereby very big increase the structural strength that tubing connects, improve the anti-pulling performance that tubing connects, adhesive layer between the two plays adhesive effect and also plays seal action, guarantees the good sealing property that tubing connects, and can realize long-acting without leaking.
Further, described pressing section nominal diameter is 10mm～160mm, the thread pitch of thread section is 2mm～20mm, height of thread is 0.3mm～4mm, select suitable pitch and height of thread according to the caliber size of actual tubing, make connecting body and to be connected tubing riveted tight, after pressing, there will not be space.
Further, described anticreep section is polygon-shaped, can effectively prevent pipeline radial rotating.
Further, described adhesive layer adopts anaerobic adhesive, and adhesive layer anoxic in the pipe joint suppressing is solidified rapidly, plays sealing and bonding effect, thereby completes the connection to pipe fitting.
Further, connecting body is the connecting body of straight-through shape, or the connecting body of elbow-shaped, or the connecting body of threeway shape.
Compared with prior art, the utility model advantage is:
Card described in the utility model press the bonded pipe joint construction of screw thread simple, easy to operate, greatly save tubing cost and installation work-hour expense, and join strength is high, anti-pulling performance is good, good seal performance, is applicable to the connection of the thin-wall stainless steel tubing in water supply system, gas burning system; The utility model is simple in structure, is easy to realize, and economic benefit is high.
