Description
Technical field
The present invention relates to pipe fitting interconnection technique field, more particularly to a kind of pipe connecting structure.
Background technology
The conventional connected mode of at present pipeline engineering have threaded connection, be welded to connect, flange connection, groove connection, card pressure
The forms such as formula connection.Threaded connection is mainly used in low-pressure fluid conveying welded still pipe and external diameter can be with the seamless steel pipe of tapping
Connection, processing, easy to connect, but pressure-bearing property and sealing are poor, it usually needs install raw material band, raw material band tool additional on screw thread
There is contaminative；It is most widely used connected mode in pipeline engineering to be welded to connect, and interface is firmly durable, not easy to leak, joint
Intensity and tightness are high, do not need Jing often to manage after use, type of attachment environmental protection, and pollution will not be produced to circulation medium, but need
On-the-spot welding is wanted, installation difficulty of processing is larger, and time long efficiency is low, need skilled workmen, be otherwise difficult to the company of guarantee
The sealing for connecing, processing human cost is high；Flange connection is that pad is put in the flange that a pair are fixed on two mouths of pipe
Between, a kind of dismountable joint for making it combine closely, easy to assembly, efficiency high are tensed with bolt, but flange company is set
Relatively costly, the replacing maintenance cost height of binding structure；Plough groove type interface tube is processed at the pipe fitting joint such as tubing, pipe fitting position
Ring-shaped groove, with the telescopic snap joint of the compositions such as clamping piece, rubber seal and securing member, during installation, in adjacent pipe end
After putting special-shaped rubber seal, connected with split type clamping piece, it is easy to loading and unloading, but pressure-bearing property is poor, and long-term seal is poor；Card pressure
Formula connection is stainless steel tube to be inserted in pipe fitting, with special pressing tongs in pipe fitting end card pressure, makes the end of stainless steel tube and pipe fitting
Portion's simultaneously contraction distortion and produce sealing function, be generally used for water supply system, heating system etc., construction is simple, operation side
Just pipe fitting connection processing, can be whenever and wherever possible carried out, tubing cost and installation work-hour expense is greatlyd save, but card pressure easily occurs
Fold so that card pressure connects uneven and the bad situation of sealing occurs between pipe fitting, and can apply between steel pipe and pipe fitting
Anaerobic sealer is covered, precipitate is had during life-time service the medium for conveying is polluted, it is impossible to be applied to conveying
Medium has the environment of high-cleanness, high requirement.
The content of the invention
The technical problem to be solved and the technical assignment for proposing are that prior art is improved, there is provided a kind of
Pipe connecting structure, traditional pipe fitting connected mode connection sealing is poor in the current technology of solution, and packaging efficiency is low, high cost
Problem.
To solve above technical problem, the technical scheme is that：
A kind of pipe connecting structure, including pipe connector, it is characterised in that the outer wall of described pipe fitting one is provided with convex
Edge, pipe fitting one is penetrated in pipe connector, and the securing member being connected with pipe connector pushes down flange so that the end of pipe fitting one is supported

Between be provided with seal washer, the out-of-flatness position of pipe fitting end is filled up in the seal washer deformation that is squeezed, and effectively improves sealing.
Further, described seal washer is metallic gasket, and good airproof performance, resistance to pressure is good, long service life, without dirt
Dye, ensures the cleanliness factor of pumped (conveying) medium in pipe fitting.
Further, in a ring, securing member is slided over to be placed described securing member outside pipe fitting one, and securing member pushes down flange simultaneously
It is threaded connection with pipe connector, securing member is using the structure of nut and the external screw thread or interior spiral shell of setting on pipe connector
Stricture of vagina is attached, and the fastening dynamics that helicitic texture is produced can ensure that pipe fitting end is in close contact with seal washer, ensure good
Sealing, simple structure is easy to loading and unloading, low manufacture cost.
Further, the periphery of described securing member arranges prism structure, easy to loading and unloading, or on the circumference of securing member
The draw-in groove of fastening is provided with, just can only can be assembled and disassembled using matching instrument.
Further, described flange is located at the end of pipe fitting one, and flange is penetrated in pipe connector and supported with seal washer
Lean on, increase the contact area of pipe fitting and seal washer, flange and seal washer good contact, connection sealing is ensured, using end
The sealing in face can meet sealing requirements, and without the need for arranging O-ring seal etc., simple structure, packaging efficiency is high, pollution-free, meets
The requirement of high-cleanness, high conveying.
Further, described flange outwards turns down the flange of formation for the end of pipe fitting one, easy to process, live can make
Make, stabilized structure intensity is high, make motility good.
Further, described flange is perpendicular to the axial direction of pipe fitting one.
Further, described flange bends acute angle in the arc-shaped, and securing member is in match with flange against place with flange
Shape, securing member contacts closely with flange, ensures that securing member applies the active force of stable and uniform to flange, it is ensured that flange with it is close
Seal washer is brought into close contact, and improves sealing.
Further, clear opening is opened up on described pipe connector, one end of clear opening is screwed hole, and the other end is mouth
Footpath is less than the stepped hole of screwed hole, and pipe fitting one and pipe fitting two are straight-through from the insertion of screwed hole one end in the way of flange is to together with being against
Seal washer is provided between Kong Zhong, and two pipe fittings one and the flange of pipe fitting two, securing member is locked will pipe on screwed hole
Part one is pressed on stepped hole with the flange of pipe fitting two with seal washer.A securing member is only needed to when two pipe fittings are connected,
Compact conformation, parts are few, low cost, and packaging efficiency is high, good airproof performance.
Compared with prior art, the invention has the advantages that：
Pipe connecting structure of the present invention is easy to loading and unloading quick, and pipe connector and securing member all adopt metalwork,
Corrosion-resistant, pollution-free, long service life meets the demand of high-cleanness, high conveying, and using the structure of end face seal, structure is simplified,
Good seal performance, carries hydraulic pressure height, and anti-pull-out property is good, and seal washer need to be only changed in seal failure, changes maintenance cost
Low, maintenance efficiency is high.
