Description
Technical field
The present invention is to provide a kind of pipe jointer, specifically a kind of hydraulic drive type pipe jointer, the quick reparation being applicable to submarine pipeline be connected fast.
Background technique
The method that current submarine pipeline connects mainly contains flange-type and connects, welding, clamp coupling.These three kinds of time-consuming length of Placement, consumption costs is high, in case of emergency can not realize connecting fast.And due to the special environment in ocean, some mode wherein, the probability of its Joint failure is also larger.
The domestic research connected for pipeline at present is also in the starting stage, does not also have a kind of pipe jointer being realized connecting fast by hydraulic pressure.And external pipeline connects the technology and the product that there are comparative maturity with reparation aspect fast.With the intelligent flange coupling connector of Oceaneering company of the U.S. for representative, be widely applied in the connection of pipeline, there is very high market share.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic pressure that uses be fixed pipeline and seal, the hydraulic drive type underwater connector repaired fast and connect can be realized for the submarine pipelines of less than eight inches.
The object of the present invention is achieved like this:
Comprise housing 5, be connected to thread ending cover 3 and the flange end cap 13 at housing two ends, power transmission cover 4 is furnished with from thread ending cover 3 end successively to flange end cap 13 end in housing 5, promptly extruded sleeve 6 and sealed extruded cover 10, housing 5 has hand-hole 40, power transmission cover 4 with promptly leave gap with corresponding source, hand-hole 40 position between extruded sleeve 6, the centre of flange end cap 13 is shoulder hole, seal ring is arranged in shoulder hole, the centre of described thread ending cover 3 is through hole, through hole is with a sleeve, barrel forward end has opening 25, barrel forward end inwall has internal thread segment 24, power transmission is overlapped 4 inwalls and is made up of two sections of inner cylinder and the one section of inner conical surface be clipped in the middle of two sections of inner cylinder.
Hydraulic drive type underwater connector of the present invention can also comprise:
1, power transmission is overlapped on 4 outer surfaces and is had Baltimore groove 36, arranges support ring 20 at described Baltimore groove.
2, described seal ring comprises small sealing ring 11 and big sealing ring 17, is provided with spacer ring 12 between small sealing ring 11 and big sealing ring 17, flange end cap 13 has detect aperture 79.
3, also comprise position limit pin 9, housing has limit pin hole 45, limit pin hole 45 has 4-8 and circumferentially equidistantly distributes of housing, and sealed extruded cover 10 has two circle cotter ways.
Hydraulic drive type pipe jointer of the present invention, the quick reparation being applicable to submarine pipeline be connected fast.It is easy for installation, by ROV injection liquid force feed, relies on hydraulic pressure realization to the sealing of pipeline and fixes, and not needing diver.Can be whether qualified by the sealing of sealing propertytest mouth testing pipes sealing after installation.
The invention provides a kind of structure simple, connect reliable hydraulic drive type pipe jointer.It uses hydraulic pressure reliably fix pipeline and seal.Can realize repairing fast and connecting for the submarine pipelines of less than eight inches.First complete the assembling of connector according to erection drawing, idea assembling process will insert position limit pin 9 and realize installing front initial position.First pull out position limit pin 9 when mounted, with hydraulic equipment by the hydraulic oil hand-hole 40 on housing 5 to connector injection liquid force feed, be forced into setting pressure, now hydraulic oil is full of sealed extruded cover 10 and the toroidal cavity promptly between extruded sleeve 6.Under the effect of hydraulic coupling, sealed extruded cover 10 moves towards flange end cap 13 direction, and tightly pushes down small sealing ring 11, and small sealing ring 11 and big sealing ring 17 produce radial contraction under the effect of the pressure and tightly against pipeline 1, realize reliable sealing.Now inserted by position limit pin 9, position limit pin 9 will enter into pin-and-hole 63 again, even if withdraw hydraulic equipment, seal still intact.And now, promptly extruded sleeve 6 is also under the effect of hydraulic coupling, move towards thread ending cover 3 direction, thus promotion power transmission cover 4 moves towards thread ending cover direction, due to power transmission cover 4 also existing conical surface 33, now conical surface 33 will move to the top of the thread section 24 of thread ending cover 3 and thread-rolling screw section 24, and thread section 24 creates radial contraction and tightly embraces pipeline and be engaged with it, therefore can resist various External Force Acting.So far, withdraw hydraulic equipment, then connect with the pipe jointer of pipeline to two ends of two ends with flange.The present invention installs simply, need not design special loading facility, just synchronously can realize sealing with fixing.

Installation process is as follows:
(1) installed successively by part each in connector according to erection drawing, and use instrument by each screw, nut is loaded on predetermined load.
(2) need to insert connector internal depth two pipeline 1 surface markers to be connected;
(3) pipeline 1 waiting is inserted into connector inside, reaches assigned tags, thrust surface 73 close contact on the flange end cap 13 of now pipeline 1 end face to be connected and connector.Pipeline 1 is also according to said method inserted designated depth by the other end.
(4) pull out the position limit pin 9 on housing 5, then with hydraulic equipment by the hydraulic oil hand-hole 40 on housing 5 to toroidal cavity injection liquid force feed, and be loaded on predetermined pressure, make sealed extruded overlap 10 and move to two ends with promptly extruded sleeve 6, arrive specified position.
(5) extruded sleeve to be sealed 10 is with after promptly extruded sleeve 6 arrives specified position, then inserts 6 position limit pins 9 by the uniform limit pin hole 45 of the circumference of 6 on housing 5.Now remove hydraulic equipment, then the other end is connected after the same method.
(6) after treating that two ends pipeline 1 all connects, injected the hydraulic oil of suitable pressure with hydraulic equipment by the sealing detection mouth 79 on housing 5, and connect piezometer, if piezometer reading is constant after 15 minutes, good seal can be thought.
(7) if the equal good seal of two terminal adapters, now with the pipeline that two ends are flanged (FLGD), two mounted pipe jointers are connected.So far, connector installs.
