Abstract
The utility model discloses a line pipe plugging device. Temporary plugging and permanent plugging of oil and gas line pipes with various sizes can be achieved. The line pipe plugging device comprises a line pipe plugging part and a plugging implementing part. The line pipe plugging part and the plugging implementing part are connected through a lead screw. The lead screw comprises a lead screw front segment and a lead screw rear segment. The lead screw front segment and the lead screw rear segment are connected in a threaded mode at the position of a joint of the lead screw. An end portion drain plug is arranged at the end portion of the front end of the lead screw front segment. A spanner square is arranged at the end portion of the rear end of the lead screw rear segment. Force is applied through the lead screw and the plugging implementing part, and the line pipe plugging part is extruded to seal the inner wall of a line pipe. The line pipe plugging device guarantees basic requirements of safe flame operation, can be in repeated use, and is low in cost price. Not only are economic losses due to large area stopping production reduced, normal running of production is guaranteed, but also social benefit due to safe construction is provided.
Description
Technical field
Pipeline capping tools when the utility model relates to petroleum industry oil, gas pipeline hot work, particularly a kind of pipeline blocking device can be realized temporary plugging and the permanent shutoff of Multiple Type oil, gas pipeline.
Background technique
When oil depot, pumping plant carry out the pipeline modification construction, there are some production flow lines need to disconnect isolation, can construction reformation.These pipelines often have some oil gas, if will cut off shutoff, produce easily naked light, and the Security of producing is on every side brought a lot of disadvantageous factors.Method of construction commonly used is to carry out large-area stopping production operation at present, with the Security that guarantees to get angry, so not only is difficult to guarantee the Security of construction, has also caused certain economic loss.
Summary of the invention
The purpose of this utility model provides a kind of pipeline blocking device, overcome need to the stop production situation of operation of prior art production flow line construction reformation, at oil depot, when pumping plant needs hot work, in the situation of not getting angry, pipeline is cut off, the pipeline that utilizes this device shutoff to cut off, make oil, the gas of pipeline the inside isolated with extraneous air, guaranteed the Security of constructing.
Technical solution of the present utility model is: a kind of pipeline blocking device comprises pipeline occluding member and shutoff implementation section, and the pipeline occluding member is connected leading screw with the shutoff implementation section and connects.Leading screw comprises leading screw leading portion and leading screw back segment, and leading screw leading portion and leading screw back segment are threaded connection in the leading screw joint; The front end end of leading screw leading portion is provided with end part plug, and the end, rear end of leading screw back segment is provided with spanner side.By leading screw and the shutoff implementation section application of force, extruding pipeline occluding member sealing pipeline inwall.
Compared with prior art the utlity model has following useful effect: this device utilizes the cartridge of shutoff implementation section extruding pipeline occluding member, makes its expansion reach the purpose of sealing.By using this pipeline blocking device isolated by the air in oil, gas and the external world of pipeline the inside, guaranteed the Security of construction.When needing permanent shutoff, clamping sleeve and the spot welding of leading screw leading portion can be lived, leading screw back segment and application of force frame be taken off, and leading screw leading portion and pipeline occluding member are stayed the pipeline the inside.After pipeline sealing, also can be at this off-site of staying pipe blind plate of burn-oning.This device has guaranteed the basic demand of coal Gas for safety Ignition, can repeatedly use, and cost price is low.Not only reduce the economic loss that large size stops production and brings, guaranteed to produce and normally carried out, also had the social benefit of being brought by safe construction.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail.A kind of pipeline blocking device comprises pipeline occluding member and shutoff implementation section, and the pipeline occluding member is connected leading screw 5 and connects with the shutoff implementation section.Leading screw 5 comprises leading screw leading portion and leading screw back segment, and leading screw leading portion and leading screw back segment are threaded connection at leading screw joint 8 places; The front end end of leading screw leading portion is provided with end part plug, and the end, rear end of leading screw back segment is provided with spanner side 3.The pipeline occluding member comprises cartridge 6 and pressure strip 2, and cartridge 6 and pressure strip 2 are set on the leading screw leading portion of leading screw 5.The shutoff implementation section comprises clamping sleeve 7, application of force frame 1 and gland nut 4, and application of force frame 1 is set on the leading screw 5, and clamping sleeve 7 is threaded with the leading screw leading portion of leading screw 5, and gland nut 4 is threaded with the leading screw back segment of leading screw 5.Application of force frame 1 comprises top board and clamp sleeve, and the clamp sleeve bottom is cylindrical body, and its cylindrical shell both sides, top fluting is convenient to spot welding clamping sleeve 7; Top board is strip shape body, and its length is greater than the diameter of pipeline 9, with clamp sleeve upper end and top board welding.
When temporary sealing, at first pipeline 9 is cut open, the pipeline occluding member of this device and clamping sleeve 7 are connected on the leading screw leading portion of leading screw 5, put into pipeline 9.Application of force frame 1 is leaned port at pipeline 9.Screw nut 4 drive leading screws 5 and strain outward, make pressure strip 2 crush seal packing elements 6, contacts with the inwall of pipeline 9 after expanding, reach sealing purpose.
When needing permanent seal, 7 of clamping sleeves are welded in above the leading screw leading portion of leading screw 5, make pressure strip 2 push down cartridge 6, can not resilience.Rotary spanner side 3 dismantles the leading screw back segment from leading screw joint 8 again, takes out application of force frame 1 and leading screw back segment, and it remains in the pipeline 9.After sealing up pipeline 9, also can stay the outside of the tubular portion blind plate of burn-oning at this device.
