Description
Technical field
The present invention relates to change in a kind of oil field gathering and transportation operation the high pressure line valve changer of fault accessory on hydraulic oil water pipeline.
Background technology
Owing to all containing Korrosionsmedium in the water pipeline in oil field gathering and transportation operation and oil pipeline, and internal pressure is high, therefore often occur on pipeline that valve body corrosion failure, flashboard come off, steel ring and the accident such as sealing gasket seepage, ball-and-seat damage, for carrying out smoothly of ensureing to produce, prevent the pollution of the environment, avoid the generation of security incident, must be in time on pipeline, damage valve, steel ring, ball-and-seat and sealing gasket change.But, also there is no at present special replacing instrument, when field operation, not only to remove fault accessory, also must disassemble adjacent pipeline, not only workload is large, need operating personnel many, labour intensity is high, and the time is long, and pipeline tends to after taking apart because expanding with heat and contract with cold or the reason generation dilatation such as vibrations, and while causing reinstalling new accessory, pipeline cannot centering.Little install again after can also utilizing that the aids such as guide chain, afterburning thick stick, jack are powerful and correcting being out of shape, for distortion large can only carry out welding with electrogas welding.Thereby affect normal crude oil production, polluted environment, increased labour intensity, increase the generation of security incident.
Summary of the invention
The object of the present invention is to provide a kind of high pressure line valve changer that can change fast, easily and safely fault accessory on hydraulic oil water pipeline.
For achieving the above object, high pressure line valve changer of the present invention comprises changer and centralizer two parts, and described changer is made up of upper clip, lower clip, upper backup pad, lower supporting plate, fixed bar, upper fixed cover, lower fixed cover, regulating nut, jack, adjusting rod, hold-doun nut, upper clip hold-doun nut, upper clip screw rod, upper clip screw shaft, lower clip hold-doun nut, lower clip screw rod, lower clip screw shaft, upper clip nut pad, lower clip nut pad, upper clip fixed axis, lower clip fixed axis, jack fixed screw.Described upper clip and upper backup pad welding, be welded with fixed cover and hold-doun nut, hold-doun nut and adjusting rod screwed connection on upper backup pad; Lower clip and lower supporting plate welding, be welded with lower fixed cover and regulating nut on lower supporting plate, jack is fixed on lower supporting plate by fixed screw, and upper backup pad is connected by fixed bar with lower supporting plate.Upper clip is connected by upper clip fixed axis, there is screw thread card tooth upper clip inner side, and upper clip screw rod is fixed on upper clip by upper clip screw shaft, and lower clip is connected by lower clip fixed axis, there is screw thread card tooth lower clip inner side, and lower clip screw rod is fixed on lower clip by lower clip screw shaft.
Described centralizer is made up of centralizer fixed axis, centralizer screw shaft, centralizer screw rod, centralizer nut pad, centralizer nut, the left card of centralizer, the right card of centralizer, the right card of the left card of centralizer and centralizer inner side is all plane, the two links by centralizer fixed axis, centralizer screw shaft is fixed centralizer screw rod, the fastening auxiliary centralizer of centralizer nut pad and centralizer nut.
After having adopted said structure, upper clip and lower clip can be fixed on the oil-water pipeline at fault valve two with upper clip hold-doun nut and lower clip hold-doun nut respectively, rotary regulating lever makes jack head enter adjusting rod, rotate counterclockwise fixed bar and move to needed length while replacing, then unload valve fixed screw or clip on oil-water pipeline, push up needed operating distance with jack, put stay pipe, take out fault valve, install the valve that will change, the accessories such as steel ring, jack release, rotating fixed bar is withdrawn into pipeline after original position, first-class connecting screw, complete replacing operation.To the too large pipeline of skew, after can first aligning with centralizer adjustment, then to rotate fixed bar pipeline is withdrawn into original position, first-class connecting screw, pulls down high pressure line valve changer.
High pressure line valve changer of the present invention, can change the accessories such as vertical, valve, steel ring, ball-and-seat and sealing gasket laterally, on incline direction on all hydraulic oil water pipeline, when replacing, only need the connection at dismounting and change position, need not dismantle unnecessary pipeline, prevent the skew of pipeline, convenient to operation, reduce the replacing time, reduced labour intensity, avoid environmental pollution, ensured to produce and carried out smoothly, avoided the generation of security incident.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation, as shown in drawings, high pressure line valve changer of the present invention comprises changer and centralizer two parts, changer is by upper clip 1, lower clip 2, upper backup pad 3, lower supporting plate 4, fixed bar 5, upper fixed cover 6, lower fixed cover 7, regulating nut 8, jack 9, adjusting rod 10, hold-doun nut 11, upper clip hold-doun nut 12, upper clip screw rod 13, upper clip screw shaft 14, lower clip hold-doun nut 15, lower clip screw rod 16, lower clip screw shaft 17, upper clip nut pad 18, lower clip nut pad 19, upper clip fixed axis 20, lower clip fixed axis 21, jack fixed screw 22 forms.Centralizer is made up of centralizer fixed axis 23, centralizer screw shaft 24, centralizer screw rod 25, centralizer nut pad 26, centralizer nut 27, the left card 28 of centralizer, the right card 29 of centralizer.
Select and the sizeable high pressure line valve of oil-water pipeline external diameter changer, the upper clip 1 and the lower clip 2 that inner side are threaded to card tooth are placed on the pipeline that will change parts two, adjust to correct position, upper clip screw rod 13 and lower clip screw rod 16 are dialled in to clamp draw-in groove, by upper clip hold-doun nut 12 and lower clip hold-doun nut 15, upper clip 1 and lower clip 2 are clamped on pipeline.Because the internal diameter size that is separately fixed at upper fixed cover 6 on upper backup pad 3 and lower supporting plate 4 and lower fixed cover 7 coordinates closely with fixed bar 5 crest clearances, the regulating nut 8 being welded on lower supporting plate 4 is threaded with fixed bar 5 use, upper fixed cover 6 and lower fixed cover 7 can stop the left and right of dismantling pipeline to be offset with fixed bar 5, and it can only be moved linearly in the space that upper fixed cover 6 and lower fixed cover 7 and fixed bar 5 are controlled.Lay down connecting bolt or the clip that will change accessory two ends, jackscrew or the adjusting rod 10 of rotation jack 9, the jackscrew of jack 9 is entered in adjusting rod 10 following shrinkage pools, shrinkage pool can prevent jack 9 top partially, and the symmetrical jack 9 of pressing backs down pipeline to needed distance, takes out the valve that damaged, steel ring, ball-and-seat, sealing gasket etc., change new parts, jack 9 releases, with spanner symmetrical rotary fixed bar 5, pull pipeline closure.The oil-water pipeline too large for distortion skew can, with first using centralizer adjustment, be stuck in centralizer the pipeline end of skew, and fastening centralizer nut 27, makes both sides pipeline symmetry, then rotates fixed bar 5 pipeline is withdrawn into original position.Finally, tighten connecting screw or clip, dismantle upper clip 1 and lower clip 2, take off changer, just completed fast, easily and safely the task of changing fault accessory on hydraulic oil water pipeline.
