Abstract
A steam injection compensator in planar rotation comprises hoops, a high-pressure pipe A, dynamic seals, a high-pressure pipe B, a high-pressure pipe C and a high-pressure pipe D. A first hoop is in threaded connection with the high-pressure pipe A which is in right-angled connection with a high-pressure central pipe of a first dynamic seal, the high-pressure central pipe is movably and hermetically connected with a packing box which is in right-angled connection with the high-pressure pipe B, the other end of the high-pressure pipe B is in right-angled connection with a high-pressure central pipe of a second dynamic seal, a packing box of the second dynamic seal is in right-angled connection with the high-pressure pipe C, and the other end of the high-pressure pipe C is in right-angled connection with the high-pressure pipe D which is in right-angled connection with a second hoop. The steam injection compensator in planar rotation is applicable to compensation of ground movable steam injection high-pressure pipelines for thermal recovery steam injection in oil fields and is convenient to mount, the hoops at two ends of the compensator are positioned on a same plane, suspension is prevented while thermal compensation flexibility is guaranteed, and supporting is not needed, so that damage of the steam injection compensator due to stress concentration can be avoided, steam injection is guaranteed, and the steam injection compensator is long in service life.
Description
Technical field
the utility model relates to a kind of oil thermal recovery steam injection and connects the compensator using, specifically a kind of Plane Rotation steam injection compensator with land operations steam injection high pressure line.
Background technique
at present, when oil thermal recovery steam injection well adopts movable steam injection boiler construction, need to connect outlet of steam boiler to the steam injection high pressure line between steam injection well head, to carry the high-temperature steam of injection.According to standard, when land operations steam injection high pressure line connects, surpass 100m compensator need be installed, in real work, because limited by environment landform, steam injection high pressure line often need to turn to, general using compensation device turns to, former 90 degree compensators or 90 fixing degree elbow steering angles are fixed, can only change 90 degree, former 180 degree compensator indexings are flexible, but after connecting, cause steam injection high pressure line one end high, and the other end is low, high pressure line and compensator strength are larger, very easily causing stress to concentrate is damaged, the support of field by using is often opened less than due effect.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of Plane Rotation steam injection compensator is provided.
technical solutions of the utility model: comprising: hoop, high-voltage tube A, motive sealing, high-voltage tube B, high-voltage tube C, high-voltage tube D; Motive sealing is comprised of high pressure center pipe, pressure cap, packing box, seal ring, outer steel pad, graphite pads, interior steel pad.The hoop of described Plane Rotation steam injection compensator is threaded with high-voltage tube A, high-voltage tube A is connected with the pipe right angle, high pressure center of motive sealing, high pressure center pipe is connected with packing box movable sealing, packing box is connected with high-voltage tube B right angle, the other end of high-voltage tube B is connected with the pipe right angle, high pressure center of motive sealing, the packing box of motive sealing is connected with high-voltage tube C right angle, and the other end of high-voltage tube C is connected with high-voltage tube D right angle, and high-voltage tube D is connected with hoop right angle.
interior steel pad, graphite pads, outer steel pad are from inside to outside equipped with successively in motive sealing in above-mentioned Plane Rotation steam injection compensator between packing box and high pressure center pipe, and the pressure cap that seal ring is housed is connected with packing box internal thread, and outer steel pad is compressed.
the beneficial effects of the utility model are: be applicable to the compensation of oil thermal recovery steam injection land operations steam injection high pressure line, easy for installation, the hoop at compensator two ends is in same plane, when guaranteeing thermal compensation Telescopic, can prevent unsettled, without support, can prevent the concentrated steam injection compensator that damages of stress, guarantee steam injection production, long service life.
