Abstract
The utility model discloses a pipeline connecting device, and belongs to repairing or connecting devices to the damaged positions or broken positions of a pipeline. The pipeline connecting device comprises a straight pipe and flange plates. The number of the flange plates is two. Two ends of the straight pipe are in shape of a trumpet, and the two ends of the straight pipe are both connected with the flange plates. The pipeline connecting device is used, so that the phenomena of water leakage, gas leakage and the like on connecting portions can not happen. Moreover, the pipeline connecting device can enable pipelines after being connected to be not disturbed by geological subsidence or other external force so that secondary breakage or twist is avoided.
Description
Technical field
The utility model discloses a kind of assembling pipe joint, belong to the reparation or the coupling arrangement that pipeline there are the positions such as damage, fracture.
Background technique
Existing movable joint pipe joint is made of two adapter terminations and an attaching nut, and taking over the junctions, termination at two is shoulder applying forms, and stuffing box packing is filled in takes between termination and the attaching nut three.When installing and removing because of pipeline, it axially can not play, and this pipe joint is because the restriction of shoulder mesh form, makes its radially direct mutual dislocation, brings very burden to dismantle, and has increased labor intensity.Simultaneously, because the attaching nut is unique connection fastening piece, and stuffing box packing is filled in again it and takes between the termination, so at the maintenance joint, must cut off the water in (or gas) when changing filler, can give and produce or live and bring greater loss.
The patent No. having occurred subsequently is 94215778.4, and denomination of invention is adjustable screw-threaded tube joint, and the day for announcing is the patented technology scheme on February 27th, 1991.This patented technology scheme is: two adapter terminations are made respectively be with externally threaded shaft type and tapped cartridge type, and with its connection that cooperatively interacts, the male thread portion in shaft type adapter termination is rotary with an adjustable limiting spare simultaneously.Connecting under the tightening state, this bounding means divides cartridge type to take over termination one end is taken in the termination near shaft type end face applying compression, by regulating bounding means, two of capable of regulatings are taken over the degree of depth that the termination screws mutually, take over the inboard that the termination is close to the place at bounding means and cartridge type, stay a little space-filling stuffing box packing, this bounding means preferably adopts the nut form.The employing technique scheme has: 1, during the dismantle pipeline, only need unclamp and return bounding means, then can therefrom screw out also by the pipe head that turn cartridge type adapter termination will link with it and can carry out radial misalignments, thereby reduce Pipeline damage, reduce labor intensity, improved working efficiency.2, when maintenance or replacing stuffing box packing, only need unclamp bounding means and can realize, (or gas) need not to cut off the water.But, because the thing thread connecting mode that above-mentioned patented technology scheme adopts, need to be to the pipeline tapping that is connected, or leave in advance the silk mouth, so just strengthen difficulty of construction, or construction is brought narrow limitation, and the bad defective of sealing also appears in the pipe fitting that this mode connects.Again, what this mode adopted is the equal of hard connection, and secondary breakdown is appearred in pipe fitting, particularly runs into the geology sedimentation, and connecting head just is easy to destroyed.
Summary of the invention
For avoiding above-mentioned technical problem, the utility model provides the omission phenomenons such as leaking can not appear in a kind of coupled position, gas leakage.And this device also has the interference that can not be subjected to geology sedimentation or other external strength to the pipeline after connecting, and the connection set of secondary breakdown or distortion occurs.
For realizing above-mentioned technical purpose, the technical solution of the utility model is as follows:
A kind of assembling pipe joint comprises a straight-through tube 1, flange plate 2, and described flange plate 2 is two, and it is characterized in that: the two ends of described straight-through tube 1 are horn-like, and the two ends of described straight-through tube 1 all connect with flange plate 2.
The annular ridge 3 that the inwall that the utility model also is included in described straight-through tube 1 all arranges near opening.
Also be provided with seal ring 4 between flange plate 2 described in the utility model and the straight-through tube 1.
Because the utility model has adopted technique scheme, therefore, has the following advantages:
At first, because the two ends of straight-through tube are horn-like, not only make things convenient for stretching into of fracture pipeline, also laid a good foundation for the connection of flange plate, therefore, when the fracture pipeline is all stretched at the two ends of straight-through tube, adopted flange plate to connect as one firmly between the two;
Secondly, inwall at straight-through tube is provided with annular ridge near opening, that the fracture pipeline is played position-limiting action, after the fracture pipeline is all stretched at the two ends of straight-through tube, certain distance is arranged between the fracture port all the time, so that connection set after the interference that runs into geology sedimentation or other external strength, has corresponding displacement space, secondary breakdown or distortion can not occur;
The 3rd, between flange plate and straight-through tube, also be provided with seal ring, effectively played the effect of sealing, can not occur leaking, gas leakage etc. omitted phenomenon.
Working principle of the present utility model and mode are:
After fracture, breakage appear in pipeline, pipeline is disconnected, make the two ends of the pipeline of disconnection stretch into respectively the two ends of assembling pipe joint described in the utility model, after adding upper sealing washer between the pipeline that is connected and this connection set, the employing flange plate is fixed, and can finish connection.At this moment, seal ring not only is subject to the radial pressure between pipeline and the straight-through tube, also is subject to the axial pressure from flange plate and straight-through tube, and therefore, sealing effect is fairly good.Here, it is best especially adopting reducing flange.
