It can form fire independent series products. Compared with the existent technology, the invented device is simple in structure, good in sealing property, broad in adaptability, bealiful in moulding, etc.
Description
The present invention relates to a kind ofly be used for various pipelines especially for the speed of various trunkings (as valve, instrument, transducer, elbow, threeway etc.) connection, fast dismantling device.
The pipeline of conveyance fluid is used very wide in people's life, in producing, from oil, natural gas transport, urban duct engineering, to recycled water in family, combustion gas, heater pipe ... all trades and professions, every household is not all from.Yet the connection of pipeline is unsatisfactory always, we met the pipe tapping, twined adhesive tape, loaded down with trivial details work such as twisted with pipe wrench, if pipe has been broken or has been changed valve, gas meter, complex procedures, often get rusty twist motionless, can not get any more ... that vexatious strength is really want they have been pounded.Though nowadays family expenses have had the FERRULETYPE interface, be only applicable to cover and mould flexible pipe, the metal hard tube is still used the same old stuff.For industrial pipeline, except above-mentioned silk mouthful connects, also have flange plate bolt to tighten up and weld, these conventional methods, site operation instrument, operating condition are had relatively high expectations, and waste time and energy, and often because of connecting bad or welding bead slag inclusion, pore connect badly, cause leakage.
For solving an above-mentioned difficult problem, the researcher has made extensive work in recent years both at home and abroad, has obtained certain progress.As domestic relevant patent (title: " pressure piping quick jointer " just arranged; The patent No.: 95222256.6), can represent this field prior art substantially, have advantages such as easy for installation, good seal performance.But its exists following obviously not enough: the one, and used part is more, and connecting screw thread will be with dextrorotation and left-handed two kind, and structure still can be simplified; The 2nd, applicability is limited, and two pipes directly connection are better, and then advantage is not obvious to be used for elbow, threeway etc.; The 3rd, because the restriction of structure, its sealing, robustness are still waiting further raising.Four particularly, to quick mounting, the replacing of various trunkings, or deals with burst accident (as pipeline burst), do not have desirable solution so far both at home and abroad.
The purpose of this invention is to provide a kind of pipeline speed multi pack and put, it is simple in structure, beautiful shape, wide, the excellent performance of applicability, especially former pipeline is not done any transformation, can simply promptly assemble or change pipeline and various trunking.
The purpose of invention is to realize (referring to Fig. 1) like this: this device is made up of fast union nut, seal ring and profile of tooth Taper Pipe, it is characterized in that: the end face of screwed adapter (4-1) is on the same planar S with the end that connects of being taken over (5); Locate to have seal ring (2) near the S plane in that pipe is outer, the preferable shape of it and profile of tooth Taper Pipe inner chamber connecting part is the right angle; Be provided with the conical surface that aims at the crush seal circle in the speed union nut (1-1), coupled is the long cylinder chamber, and the chamber transversal is positioned at the middle part in seal ring cross section; In cylindrical cavity, be provided with slidably profile of tooth Taper Pipe (3-1), the preferred gradient rectangle of profile of tooth, the lonely face that unauspicious pressure connection is taken over should be handled according to different situations: generally keep the nature machining state; Adopt non-skid feature as increasing the roughness of lonely face when pressure is high; Under high pressure very, cambered surface can be established the arc pointed tooth bar of aculeolus or protrusion, and this tooth bar is the inclined-plane to end face not, another side vertical with pipeline (, being called for short " speed connection 1 type " by the formed fast joint product of this public technology).
Said apparatus can be realized all purposes of the present invention.Compared with prior art, following " six big advantages " arranged:
1. simple in structure, cheap.Like product is made of four parts at least, and the present invention only uses three, under certain condition only with two, and only uses right-handed thread, structure to be simplified to and can not to have streamlined any further, and is also like this after thousand; Because each part in advance can be in plant layout production, make the scene execute condition and program greatly simplifies, saved human and material resources, accelerated project progress, so its overall cost is more cheap, more effective than conventional method;
2. sealing is excellent, and is durable.Find out its " richly endowed by nature " from textural: seal ring only depends on the pressurization of profile of tooth Taper Pipe unlike existing technology, also has fast union nut to finish jointly, is " dual fail-safe "; The little sharp Saw blade that its profile of tooth Taper Pipe is not held is screwed into can thrust under exerting pressure to be taken at fast union nut it is clenched, and " perfectly safe ", and prior art I had never expected and establishes little sharp sawtooth, makes the high pressure lower link not firm; If established, can thrust too early and be taken over, the profile of tooth Taper Pipe moves no longer inwards, and the function of pressure seal ring is promptly lost, and will have a strong impact on sealing, " attending to one thing and lose sight of another ";
3. applicability is extremely wide.High temperature resistant, high pressure resistant, can be used for various pipelines: big, little; Soft, hard; Straight tube, bend pipe; Threeway, how logical; Various trunkings, terminal equipment, block device
4. beautiful shape, generous.There is one section ring cavity slightly thicker than phase adapter at speed union nut two ends, can cover the silk mouthful or the sawtooth of the inside, and interface concisely cleans, and no matter house fitting or pipework all can be beautification of the environment contribution;
5. environmental protection.Existing some part of technology is immersed in the fluid, perishable polluting, and the present invention's sealing narrow slit loop contacts fluid of seal ring only, thereby corrosion-resistant, the life-span is long;
6. mounting or dismounting are very convenient.This is a main purpose of the present invention, also is sharpest edges.Because of disclosed herein as well is under a total inventive concept other four kinds each has something to recommend him, can independently become the technological scheme of patent, so be placed on hereinafter introduction in the lump.

Please referring to Fig. 5, " speed connection 5 types " are characterised in that: seal ring (2) and profile of tooth Taper Pipe (3-3) all are located at the inside of adapter (4-5), because this model is suitable for joining terminal equipment (9 most, as water tap), for meeting the operating habit that dextrorotation is tightened, preferred left-handed thread between its adapter and the fast union nut (1-5).
In addition, the above-mentioned various fast union nut that adopts, seal ring and profile of tooth Taper Pipe have common technical characterstic and requirement:
The profile of tooth Taper Pipe adopts than the hard elastics made; The preferred gradient rectangle of profile of tooth, outer Dou cambered surface roughness is little, and the equal chamfering of all ribs can be coated with lubricant oil in case of necessity; The root system that its pressurized bending place is a tooth be screwed into moment than book to reduce fast union nut; The lonely face that unauspicious pressure connection is taken over should be handled according to different situations: generally keep the nature machining state; Adopt non-skid feature as the roughness that increases lonely face etc. when pressure is high.
Can establish one section ring cavity slightly thicker in the pipe of speed union nut two ends, make beautiful shape than phase adapter; The Dou degree of inner conical surface should be consistent with the Dou degree of being pressed the profile of tooth Taper Pipe, and its numerical value should comprehensively be determined according to seal request, overall anti-dial-out, bend resistance performance and the lonely surface state of pressing connection to be taken over; The outside can be set as hexagonal, anise or other is prismatic, also can adopt combination such as annular knurl, the recessed tooth bar of strip and above-mentioned measure etc.
The seal ring selected materials should be determined according to temperature, the pressure of institute's conveyance fluid and fluid, but butyronitrile rubber, polyamine fat, silicon, fluorine rubber or other NEW PLASTIC material, but its sectional shape rectangle, runway shape, general choosing is circular, also can get up to be sugar coated haws shape by two or more circular connection; Under high pressure, also can form jointly by adding a metal spacer ring in the middle of two seal rings.
Trunking (8, adopt the valve, instrument of interface of the present invention etc. as two ends) is installed, and two are taken over the distance that should stay between (5), and speed is joined 1 type or 3 types should equal or be slightly larger than two length L of taking between end face of trunking; Should equal or be slightly larger than two total length and fast union nuts of taking between end face of trunking to 2 types and connect end tube section length N sum.
The fluid of taking over (4) goes out the auspicious sealing attitude that is, aim at plugging mouth device (10), it has solved a difficult problem for a long time in a lot of occasions of great use, can independently become series product.。
Introduce the most important purpose of the present invention at last, how to make realization quickly by above-mentioned each device side:
The internal diameter that external diameter of being taken over and fast multi pack are put adapts, and this is necessary; End face is smooth, vertical with pipe and remove burr and foreign matter, and this is that all install total requirement.Two directly link with the bore pipe, and " speed connection 4 types " are more suitable for, and two tubes need only be inserted, and tighten i.e. completion; For the connection of different bore pipes, or angled, or threeway, how logical, the present invention adopts 1 type or the very easy respective transducer of making of 3 types, and installing is to insert one to twist promptly equally.
Two of trunking connect end and generally establish 1 type or 3 types, and installation process as above.As a rule, two quilts are taken over fixing, as long as the spacing between two pipes meets aforementioned requirement, install also very simple: at first equipment two ends fast union nut, seal ring and profile of tooth Taper Pipe separately is enclosed within respectively and taken over, put into trunking again, each part is moved on to the position inwards, and fastening nut is promptly finished.
If two quilts are taken over fix tightly and tension or the power of being bent is little, can save the profile of tooth Taper Pipe like this and make structure more simplify (as shown in Figure 4); This situation speed connection 2 types just have showed its exclusive advantage: put into two after two fast union nuts need only being screwed home inward by between adapter, twist the roof pressure sealing more outward and get final product, always take time only several seconds!
By all made products of the present invention, comprise various valves, instrument, transducer, elbow, threeway, plugging mouth device ... not only install very simply, its dismounting is " ery easy " especially, and general one minute, special several seconds can be finished.
