Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.For the person of ordinary skill in the field, to the detailed description of model utility by reference to the accompanying drawings, will readily appreciate that above-mentioned purpose of the present utility model, feature and advantage.
With reference to Fig. 1 and 2, show and have the first naked pipe 1 of bell 12 and be used for the second naked pipe 2 that is provided with pin shaped part 16 with the socket of the first naked pipe 1.
Have cylindrical part 18 for bell 12, this cylindrical part 18 along the longitudinal axis 20 extends.The internal diameter in the hole that the cylinder shape inner wall 22 of cylindrical part 18 forms is slightly smaller than the external diameter of the cylindrical outer wall 24 of the second naked pipe 2, thus in the middle of wall 22 and 24, form closely, metal to metal, mechanical drive fit (with reference to Fig. 2).
And then bell 12 cylindrical part 18 is the also cone-shaped section 28 that extends of axis 20 along the longitudinal.Cone-shaped section 28 begins to extend from the separating surface 29 of cylindrical part 18, and inwardly towards the longitudinal axis constriction, last body with the first naked pipe 1 continues.Cone-shaped section 28 and the radial plane punishment circle of pipe 1 at point 30 places.From separating surface 29 to point 30, form taper angle 21 between the longitudinal axis 20 of the bus of cone-shaped section 28 and pipe 1.
The second naked pipe 2 has the cylindrical part 32 as body, and this cylindrical part 32 extends between point 34 and separating surface 36.What continue with cylindrical part 32 is the pin shaped part 16 that always extends to pipe 2 free end face 40, and described pin shaped part 16 comprises cone-shaped section 38.From separating surface 36 to end face 40, the inside constriction of the male cone (strobilus masculinus) of cone-shaped section 38 shows as between the longitudinal axis 20 of the bus of cone-shaped section 38 and pipe 2 and form taper angle 23, but the inwall of whole the second pipe 2 keeps being continuous straight line.
According to the utility model, angle 23 is greater than angle 21, thereby when pipe joint forms (Fig. 2), formed space 42 between the inner conical surface 44 of the cylindrical conical surface 43 of cone-shaped section 38 and cone-shaped section 28.Space 42 roughly extends to end face 40 from separating surface 36.The radial width 41 of space 42 between relative trochoidal surface 43 and 44 be 40 equably increases from separating surface 36 to end face.Width 41 size in space 42 is determined by the angle extent between angle 21 and 23.Wherein, differential seat angle is at least 2 degree.
The axial length in space 42 is chosen to can not limit the hole by pipe 1 and 2 pipes that form.Whether wall thickness and the pipe of the accurate dimension of concrete pipe joint and the size that the tapering differential seat angle will depend on pipe to be connected, pipe are determined for having coated inside.
In practical operation, the method that forms pipe joint can be implemented with naked pipe and undercoating pipe, although the internal coated pipe of the method is especially practical.Described method is included as a pipe and 1 at one end makes bell 12, and in an end manufacturing pin shaped part 16 of another pipe 2.Before making joint, the outer wall 43 of the cone-shaped section 38 of pin shaped part 16 at first is coated with the flexible adhesives (for example liquid epoxies) of enough thick-layers, then will sell shaped part 16 and little by little, effectively and fully be socketed in bell 12 inside, so flexible adhesives little by little is extruded along axial direction from space 42, this extruding action has gradually produced useful effect: (1) outer wall 43 is tending towards tackiness agent is applied the pressure of dispersion, and this is required for firm connection with being connected between the pipe; (2) 42 tackiness agents of extruding have also formed mouth 52 the ring 50 of sealed pipe joint from the space so that manage 1 and the inwall of the whole pipe joints that consist of of pipe 2 substantially be continuous straight line.Therefore avoided the common shortcoming of most of pipe joints: form burr at relative wall 43 and 44 inevitably, so that at joint formation " blank " or aperture.This blank soundness that has butt joint and corrosion resistance are very unfavorable, further reduce simultaneously the probability that turbulent flow produces.
In addition, differential seat angle between angle 21 and 23 must at least 2 degree, thereby flexible adhesives can be extruded under the pressure that is fit to, and can not form blank or aperture, thereby and the tackiness agent of spendable enough capacity wide ring 50 covers mouth 52 fully so that form fully in space 42.
Fig. 3 and 4 basic similar with Fig. 1 and 2 has undercoating 60 except managing 1 and 2, and in pipe 1, undercoating 60 extends to a little 61 and is close to the cylindrical part 18 of (preferably not having to arrive) and the separating surface 29 between the cone-shaped section 28.In pipe 2, coating 60 covers whole inwalls and the fraction of 38 point 62 from end face 40 to outer wall.
By between angle 21 and 23, making the differential seat angle of at least 2 degree, after tackiness agent solidifies, tackiness agent 42 has interiorly formed tapered wall 65(Fig. 4 continuous, that solidify in the space), and form ring 50 at the mouth place, and then the coating on the inwall of bell section 60 becomes fully and coating 60 bridge joints on the inwall of pin shaped part, inwall for pipe joint provides continuous interior coating in the whole process that pipe joint forms thus, does not expose to the corrosive fluid that flows by the pipe carrying thereby do not have exposed metal.
Therefore, can prevent from being located to corrode at the point of the most fragile of pipeline (that is, mouthful 52) by any corrosive fluid (for example hydrocarbon products) of pipeline carrying the metal of pipeline.The fluid binder that promptly solidifies to form ring 50 and solidify tapered wall 62 provides perfect sealing between relative cone- shaped wall 43 and 44.
Cooperation tight, metal to metal between cylindrical part 18 and 24 is connected with anti-leak for joint provides required high mechanical strength in undercoating pipe and naked pipe, thereby protective bulkhead 65 and ring 50 avoid standing too much tension force and warping stress.Further, the inwall of whole pipe joint is continuous straight line, has greatly reduced fluid and carry the probability of turbulization in pipeline, has kept the flow rate of fluid.
The equipment 70 that is suitable for making joint of the present utility model is schematically illustrated in Fig. 5-7.Layout shown in Figure 5 is relevant by pipe 1 and 2 pipe joints that form with manufacturing, and pipe 1 and 2 has had pin shaped part and the bell section at the place, end that is formed on them.Equipment comprises barrier structure 71A and the 71B of two positioned opposite.Each barrier structure has center hole, and the pipe 1 that is used for being socketed and 2 longitudinal axis 20 run through this center hole and coaxial with it.Be extended with conical cavity 74 from the inside face of each block piece, this conical cavity 74 is inwardly towards longitudinal axis 20 constrictions.Cavity 74 formed instrument 75,82 and 92 selectively be positioned at wherein accommodating chamber.Each instrument is by locking devicen 76 and 77 manual lockings (only shown in Figure 5 on block piece 71B in order to simplify view) in place.Block piece 71A and 71B connect actively by a pair of hydraulically operated cylinder 72A and 72B.
How telescopically, advantageously and fully the cone-shaped section 38 that Fig. 5 shows pin shaped part 16 inserts bell 12 cylindrical part 18.The contractibility of the joined wall of bell and pin shaped part does not surpass the elastic limit of the material of pipe, and firmly mechanical drive fit and suitable restraining force will be kept always.
In Fig. 6, show equipment 70 and how to be applicable to simply form bell section.Wherein, cylindrical part 18 and bell 's 12 tapered wall 28 can strongly be inserted cylindrical tube 1 by the stiff spindle 90 of instrument 92 and forms.Instrument 92 can be a unit that is tacked tightly by the mechanism of U-shaped folder-bolt.Axle 90 is alignd coaxially with the longitudinal axis 20 of pipe 1.Because pressure is applied by cylinder 72A and 72B, therefore block piece 71A and 71B force the cylinder-shaped end of tubular portion 1 to cross the axle 90 that forms tapering part 28 towards mobile each other.
In Fig. 7, show equipment 70 and how to use formation pin shaped part, at first, the mode that the inwall of pipe 2 tip side utilizes related domain to be fit to is arbitrarily become predetermined skew wall by machine cuts, thereby then utilizes equipment 70 to form so that manage the pin shaped part 16 that 2 inwall is continuous straight line with the mode opposite with the mode that forms bell 12 this tip side that bends inwards.Instrument 82(Fig. 7) similar with instrument 92, except having cavity 81, its axle 80 is configured as for bending tip side formation pin shaped part 16.The conical end of cavity 81 forms cone-shaped section 38.Instrument 82 is held in place by U-shaped folder-bolt arrangement 83.
As a kind of alternate embodiment, can be directly the outer wall of tip side by machine cut pipe 2 to form so that manage the pin shaped part 16 that 2 inwall is continuous straight line.
Although in pipe manufacturer factory, pin shaped part and bell section are formed by automated machine, have portable set 70 in related domain expectation the pipeline that breaks is keeped in repair, and pass through to make pin shaped part and bell section with 92 with the pipe at new different bores and wall thickness at the instrument 75,82,90 of block piece 71A and the 71B different bores of exchange and function simply.Particularly, in actual maintenance process, by the pipe joint in the pipeline of bad connection is excised, the on-the-spot 70 pairs of pipes to be processed or maintenance of portable set that can directly utilize push or bend cutting operation formation pin shaped part and bell section, thereby are assembled into quickly and easily new pipe joint.Compare the welding or be spirally connected, the more simple efficient and saving cost of pipe joint of the present utility model, the pipe seal intensity that forms simultaneously is good, mechanical connection tight and can reduce the turbulent flow phenomenon, and this scheme than other known pipe joints is much outstanding.
It should be noted that; the above only is preferred embodiment of the present utility model; be not so limit scope of patent protection of the present utility model, the utility model can also carry out to the structure of above-mentioned various component the improvement of material and structure, or adopts the technical equivalents thing to replace.So the equivalence that all application specification of the present utility model and diagramatic content are done changes, or the safety locking pipeline connected system that directly or indirectly uses the described pipe joint of present technique and contain pipe joint comes the connection metal pipeline, no matter place to use (ground, underground, wait under water) is no matter and use object (transport gas, conveying water, conveying crude oil etc.) all to be contained in the scope that the utility model contains.
