Abstract
The utility model discloses a flange deviation rectifying device which is a special tool for conducting deviation rectifying and centralizing during flange connection and installation in the pipeline flow. The device comprises a fixed clamp, a pull rod, a support arm and a lead screw. The fixed clamp is installed at one end of the pull rod, the other end of the pull rod is fixed on the support arm, the lead screw is installed at the other end of the support arm, and the fixed clamp and the lead screw are fixed on two flanges which are staggered respectively to enable the two flanges to be subjected to relative displacement to achieve the concentric effect to facilitate connection. The flange deviation rectifying device overcomes the shortcomings of an original flange staggered connection method, solves the problem of force application direction deviation caused by absence of attaching force bearing points, and achieves the aims of saving time and labor and connecting flange pipe fittings and valves of the pipe fittings safely and conveniently. The flange deviation rectifying device is simple in structure, easy to manufacture, convenient to carry and safe and reliable in work, greatly reduces labor intensity of workers and improves working efficiency.
Description
Technical field
The utility model relates to the regulating device of flange in pipeline flow process, and flange plate Deviation rectifier is particularly a kind of special tool to the righting of rectifying a deviation during flange plate connection in pipeline flow process.
Background technique
In petroleum industry, well head production procedure is the important device that connects wellhead production valve and back pressure valve, by it, realizes being connected of oil pipe and gathering and transferring process, and can be used to survey time pressure, amount temperature, the regular job such as draw oil sample.But when workover eration, for ease of workover eration, well head production procedure needs dismounting.
After workover eration completes, most of workload of preparing for driving a well is to connect well head production procedure, generally needs three people to coordinate.Run into the situation of well head production procedure distortion, the flange plate in flow process and the dislocation of back pressure valve flange plate, cause connection difficulty.Above-mentioned situation, the Shi Douhui that drives a well of the operation well 30% occurs.Current solution is to adopt the mode that manpower pulls, crowbar is prized, coir rope twists, tractor pulls to correct, and these several modes exist following shortcoming:
1, there is no good force bearing point, be not easy to operation.
2, account for the well time long, affect oil well output.
3, there is certain potential safety hazard.
When removing and installing, equally also there is the installation connection difficult problem that staggers and cause due to two flange plate in the pipe fitting valve that the various flanges that in addition, field produces is used connect.Therefore, production scene in the urgent need to a kind of not only safety, but also practical flange plate dislocation after correction instrument.
Summary of the invention
The purpose of this utility model is to provide flange plate Deviation rectifier, after can safely, easily the flange plate of dislocation being corrected, links together, and overcomes the existing defect that flange plate correction mode is existed, and easy-to-operat, increases work efficiency.
For achieving the above object, the technical solution of the utility model is: flange plate Deviation rectifier comprises fixing hoop, pull bar, support arm and leading screw, fixing hoop is equipped with in pull bar one end, the other end is fixed on support arm, the other end of support arm is equipped with leading screw, and fixing hoop and leading screw are separately fixed on two flanges that stagger.
Compared with prior art the utility model has the advantage of; The utility model is according to screw thread rotation moment, to produce the principle of displacement, and this instrument is arranged on two flanges that stagger, and rotating threaded shaft, can make the flange plate generation relative displacement of these two flanges reach with one heart, thus convenient connection.This instrument has overcome the shortcoming of original flange dislocation connecting means, has solved without a difficult problem of adhering to force bearing point and cause power thrusts deviation, can reach the object of time saving and energy saving, safe ready ground adpting flange pipe fitting and valve thereof.The utility model is simple in structure, easy to manufacture, easy to carry, safe and reliable, has significantly reduced workman's labor intensity, has improved working efficiency, has obvious economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, referring to Fig. 1, flange plate Deviation rectifier comprises fixing hoop 1, pull bar 2, support arm 3 and leading screw 4, and fixing hoop 1 is equipped with in pull bar 2 one end, the other end is fixed on support arm 3, and the other end of support arm 3 is equipped with leading screw 4.The internal diameter of fixing hoop 1 conforms to the body external diameter of flange, and its opening is provided with wing limit, is bolted.Leading screw 4 front ends are provided with top screw seat 5, and its rear end is provided with spanner side, can mounting knob 6 or directly use the spanner application of force to rotate.Also can in punching ，Qi hole, the rear end of leading screw 4, insert application of force thick stick, rotational lead screw 4.The front end arc of top screw seat 5 coordinates stability under loading with flange plate body, and rear end is provided with the region between the heart and the diaphragm hole, the front end body of rod transition fit of the blind hole of top screw seat 5 rear ends and leading screw 4, and when leading screw 4 rotates, top screw seat 5 is not with its rotation.
During operation, flange plate Deviation rectifier is arranged on the body of upper flange by fixing hoop 1, support arm 3 is alignd with the center line of two flange plate staggered positions, the upper-lower position of simultaneously adjusting fixing hoop 1 makes top screw seat 5 aim at the flange plate of lower flange.Tighten fixing hoop 1, pulling handle 6, make leading screw 4 displacements, the body of upper flange is as the strong point, the flange plate of lower flange is as force bearing point, thereby upper and lower flange plate produces to relatively move and resets with one heart, at this moment packs flange gasket into, and first-class flange bolt can be realized the connection between two flanges.
