Description
Technical field
The present invention is to provide a kind of pipe jointer, specifically a kind of hydraulic drive type pipe jointer is applicable
The quick reparation of Yu Haiyang pipeline is connected with quickly.
Background technology
The method of current submarine pipeline connection mainly has flange form to connect, welding, clamp coupling.These three connected modes
Time-consuming length, consumption costs is high, can not in case of emergency realize quickly connection.And due to the special environment in ocean, wherein
Some modes, the probability of its Joint failure is also larger.
The research connected for pipeline domestic at present is also realized quick without one kind also in the starting stage by hydraulic pressure
The pipe jointer of connection.And the pipeline of foreign countries quickly connects the technology and product for having comparative maturity with reparation aspect.With the U.S.
The intelligent flange coupling connector of Oceaneering companies is representative, is widely applied in the connection of pipeline, is accounted for market very high
There is rate.
The content of the invention
Pipeline is fixed and sealed using hydraulic pressure it is an object of the invention to provide one kind, for less than eight inches
Submarine pipeline can realize the quick hydraulic drive type underwater connector repaired and connect.
The object of the present invention is achieved like this：
Including housing 5, the thread ending cover 3 and flange end cap 13 at housing two ends are connected to, from the end of thread in housing 5
The end of lid 3 has been sequentially arranged power transmission set 4, promptly extruded sleeve 6 and sealed extruded set 10 to the end of flange end cap 13, and note is provided with housing 5
Enter hole 40, the gap corresponding with the position of hand-hole 40, flange end cap 13 are left between sealed extruded set 10 and promptly extruded sleeve 6
Centre be shoulder hole, arrange sealing ring in shoulder hole, the centre of the thread ending cover 3 is through hole, and through hole is with a set of
Cylinder, barrel forward end has opening 25, and barrel forward end inwall has internal thread segment 24, and power transmission covers 4 inwalls by two sections of inner cylinders and is clipped in two
One section of inner conical surface in the middle of section inner cylinder is constituted.
Hydraulic drive type underwater connector of the invention can also include：
1st, power transmission to be covered and be provided with Baltimore groove 36 on 4 outer surfaces, and support ring 20 is set in the Baltimore groove.
2nd, the sealing ring includes small sealing ring 11 and large sealing packing ring 17, is set between small sealing ring 11 and large sealing packing ring 17
There is spacer ring 12, detection hole 79 is provided with flange end cap 13.
3rd, also include spacer pin 9, limit pin hole 45 is provided with housing, limit pin hole 45 has 4-8 and at one of housing
Equidistantly distributed on circumference, two circle cotter ways are provided with sealed extruded set 10.
Hydraulic drive type pipe jointer of the invention, it is adaptable to which the quick reparation of submarine pipeline is connected with quickly.It pacifies
Dress is convenient, and hydraulic oil is injected by ROV, realizes the sealing and fixation to pipeline by hydraulic pressure, and need not dive under water
Member.Can whether qualified by the sealing of sealing propertytest mouthful detection seal for pipe joints after installation.
The invention provides a kind of simple structure, reliable hydraulic drive type pipe jointer is connected.It uses hydraulic pressure pair
Pipeline is carried out reliable fixed and sealed.Submarine pipeline for less than eight inches can realize quick reparation and connection.Press first
The assembling of connector is completed according to installation diagram, idea assembling process will insert initial alignment before spacer pin 9 is realized installing.When mounted
Spacer pin 9 is pulled out first, and hydraulic oil, pressurization are injected to connector by the hydraulic oil hand-hole 40 on housing 5 with hydraulic test
To pressure is set, now hydraulic oil covers 10 and the promptly toroidal cavity between extruded sleeve 6 full of sealed extruded.In the work of hydraulic coupling
Under, sealed extruded set 10 tightly pushes down small sealing ring 11 towards the movement of the direction of flange end cap 13, and small sealing ring 11 is close with big
Seal 17 produces radial contraction and tightly close to pipeline 1, realizes reliable sealing under the effect of the pressure.Now again by spacer pin 9
Insertion, spacer pin 9 will go into pin-and-hole 63, even if withdrawing hydraulic test, seal still intact.And now, promptly extruded sleeve 6
Also in the presence of hydraulic coupling, towards the movement of the direction of thread ending cover 3, so that promote power transmission to cover 4 moved towards thread ending cover direction,
Due to there is taper surface 33 on power transmission set 4, now taper surface 33 will be moved to the top of the thread segment 24 of thread ending cover 3 and squeeze
Pressure thread segment 24, thread segment 24 generates radial contraction and tightly embraces pipeline and be engaged therewith, therefore can resist various outer
Power is acted on.So far, hydraulic test is withdrawn, then the pipe jointer at two ends is connected with pipeline of the two ends with flange
Connect.The present invention installs simple, it is not necessary to design special loading equipment, just can synchronously realize sealing and fixed.
