Abstract
The utility model discloses a pipeline compensator for offshore water injection, comprising a pipeline and a compensator which is composed of a catch hoop joint, a compensation rod, a sealing assembly, a groove, a sealed chamber, a sealing ring, an outer pipe, an expansion pipe and a pressure ring. The catch hoop joint of the utility model is connected with the water injection pipeline, which enables a spherical pair of the compensator to swing in any direction in the plane perpendicular to the axis of the compensator and enables a sliding pair to move horizontally along the axis of the compensator. The utility model has the advantages that the offshore water injection pipeline can be kept from damage due to the relative swing of an oil production platform and a trestle by combining the spherical pair with the sliding pair; the utility model is mainly used for water injection pipelines of the offshore oil production platform, and the utility model can also be used for other pipeline flows requiring compensation.
Description
One, technical field
The utility model relates to producing oil, gas, water water displacement equipment from well, particularly a kind of sea filling pipe expansion loop.
Two, background technology
The filling pipe of offshore production platform behind each marine production platform bottom, " is climbed " production platform by the standpipe stake through the seabed at present, is branched off into each water injection well through trestle again.All filling pipes all are that " firmly " connects, and are to flexibly connect between thirty years of age pile tube and trestle, trestle and the production platform.When the sea runs into stormy waves or transportation ship stop production platform, can cause waving relatively or misplacing between standpipe stake, trestle and the production platform, the filling pipe fracture often takes place in this case, directly influence the problem that reason is produced.
Three, summary of the invention
The technical problems to be solved in the utility model provides a kind of sea filling pipe expansion loop, solves the filling pipe breakage problem that exists in the above-mentioned background technology effectively.
The technical solution of the utility model is to connect an expansion loop that has clip head, compensation bar, black box and groove, closed chamber, sealing ring, outer tube, telescoping tube and pressure ring to constitute in filling pipe.The clip head connects filling pipe, and telescoping tube and compensation bar are connected on the clip head, and the other end of telescoping tube is packed in the outer tube, and the other end of compensation bar matches with outer tube, seals mutually by closed chamber.The other end of telescoping tube has with outer tube wall and matches, and the outer step of linear slide therein, and black box and the mounting groove thereof that seals mutually with outer tube wall arranged on this outer step.One end of compensation bar has with the sphere of closed chamber and outer tube one end the sphere that matches, seals mutually.One end of outer tube has the Internal Spherical Surface that seals mutually, matches with the spherical outside surface of compensation bar one end.One end of closed chamber matches by the spherical annular seal space of forming with an end of outer tube with the spherical outside surface of compensation bar, the Internal Spherical Surface of sealing mutually.Be furnished with the combination seal mounting groove on the spherical outside surface of compensation bar one end.Black box is " O " RunddichtringO, on one side its cross section is spherical, all the other limits are rectangle.
Filling pipe expansion loop of the present utility model mainly is made up of a spherical pair and a moving sets.Spherical pair can with the plane of its axis normal on do the swing of any direction, moving sets can be done moving of horizontal direction along its axis, like this, just can make the filling pipe on the trestle of offshore production platform that the ability of resisting marine stormy waves and transportation ship bump is arranged, guarantee normally carrying out of offshore oil production.
Four, description of drawings
Accompanying drawing is the utility model example structure general assembly drawing
Five, the specific embodiment
As shown in drawings, clip head 1 is connected with filling pipe, and its other end connects compensation bar 2 and telescoping tube 8 respectively.The other end of compensation bar 2 is spherical, the black box 3 that is installed in the groove is arranged on it, this sphere is in closed chamber 4, match with the sphere of outer tube 6 one ends on being connected closed chamber 4, sealing mutually, the other end of outer tube 6 links to each other with pressure ring 9, black box 3 also is sphere with the face that closed chamber 4 and outer tube 6 spheres seal mutually, and its lap is a rectangle.The other end of telescoping tube 8 is packed in the outer tube 6, and outer step and groove that black box 7 is installed are arranged on it, match with the inwall of outer tube 6, sealing mutually, and linear slide therein.Closed chamber 4 is formed slidably spherical annular seal space with an end of outer tube 6.Sealing ring 5 is contained in the seal groove of outer tube 6.
