Abstract
The utility model relates to a hole opening pressure testing device for pipelines, which is used for liquid infusion pipelines and gas transmission pipelines and is composed of a hole sealing head (1), a positioning ring (3), a gate valve (4), a short pipe (5), a disc root (6), and a press cover (7) of the disc root. The hole sealing head (1) is welded on a position needing opening on the pipeline. The utility model is characterized in that after the opening pressure test, a plugging nail (2) forms threaded fixation with the interior of the hole sealing head (1), and the plugging opening with pressure is realized. The utility model has the advantages that the opening, the pressure test and the hole sealing can be completed by one step. The pipeline does not need to form back pressure to discharge liquid when the hole sealing is carried out. The construction period can be greatly reduced. The utility model is suitable for the hole opening pressure test of various liquid infusion and gas transmission pipelines.
Description
The utility model relates to a kind of transfusion, gas transmission line perforate pressure testing device.
The transfusion or the pipeline of gas transmission in use, because of change gate valve, the wiper card is stifled, pipeline freezes accidents such as stifled and paraffin blockage, all needs pipeline boring, pressure testing are rushed to repair.In the prior art, often need pipeline release, plugging hole then after boring, the pressure testing." Petroleum Engineering Construction " magazine (1993 third phase the 58th page) discloses a kind of oil transportation and has gone out the airtight boring of pipeline, jettison gear.This device is welding one short tube on pipeline to be cut, puts into the drill bit positioning ring in short tube, and adds the part cooling liquid, on connect gate valve.Open gate valve, put into the drill bit of band guide rod, gate valve top connects a short tube, the indoor asbestos seal filler of putting into of short tube top seal, compress with gland, make the drilling rod sealing, link to each other with pump, automobile oil tank at last with drilling rod and rig chucking, and with gate valve top short tube, the boring back proposes drill bit, utilize the pressure in the pipeline that the oil product in the pipe is emitted, drain the oil finish after, pipeline perforate weldering is dead.The defective that this device exists is: after boring is finished, need with the oil product in the long time blow-down pipe, perhaps pipeline is blocked, could weld perforate with method such as banket, otherwise just gate valve can only be stayed on the pipeline, be taken place easily so again to have an accident after stolen or unrelated person bump; Particularly judge under the inaccurate situation, the expensive time is handled the oil extraction operation, cause enormous economic loss in the stifled card position of generation.
The purpose of this utility model provides a kind of perforate, the pressure testing device that can take over line with pressure welding.
The utility model is by sealing of hole head (1), positioning ring (3), gate valve (4), short tube (5), packing (6), packing gland formations such as (7), sealing of hole head (1) is welded in pipeline and treats tapping, after the perforate pressure testing, shutoff nail (2) is fixed in the sealing of hole head (1) finishes the non-stop plugging perforate.
Advantage of the present utility model is: 1, perforate, pressure testing and sealing of hole can once be finished; 2, do not need pipeline back pressure exhaust fluid, reduction of erection time in a large number; 3, do not stay gate valve on the pipeline, can guarantee the safety of pipeline after the perforate pressure testing; 4, the utility model can be used for the perforate pressure testing of various transfusions, air delivering pipeline.

The utility model is further specified as follows below in conjunction with accompanying drawing:
As shown in Figure 1, sealing of hole head (1) is welded in pipeline position to be cut, the sealing of hole head has step in (1), and at step bottom car internal thread is arranged; Drill bit positioning ring (3) is placed in one, add suitable cooling liquid, gate valve (4) is connected with sealing of hole head (1), open gate valve (4), put into the drill bit (13) of band guide rod, connect short tube (5), put into asbestos packing (6) in that short tube (5) top seal is indoor, compress with packing gland (7), make the drilling rod sealing, the top body of rod and the rig (12) with drill bit (13) tightens at last.Connect the rig power supply then, hole, after boring finishes, will mention highest point on the drill bit (13), close gate valve (4), take out drill bit (13), and with short tube (5) top seal.Can open blow-down pipe (14) and carry out emptying, pressure testing operation (not exhaust fluid) this moment.After treating that this process finishes, closing gate valve (4), unload the discharge pipe line (14) that links to each other with short tube (5), then short tube (5) is unloaded on gate valve (4), the grapple device for taking out of IUD body of rod (8) is stretched into from short tube (5) bottom, stretch out from packing gland (7) upper end, and screw with grapple device for taking out of IUD handle (9).Open gate valve (4), the grapple device for taking out of IUD in sealing of hole head (1), is proposed positioning ring (3) and locates to short tube (5), closing gate valve (4) unloads short tube (5), takes out the positioning ring (3) and the grapple device for taking out of IUD body of rod (8).As shown in Figure 2, the internal thread that to mark closely screw-driver cutter hub (10) and shutoff nail (2) screws, according to the order identical the outside thread of shutoff nail (2) and the internal thread of sealing of hole head (1) are screwed with device for taking out of IUD, afterwards, to mark closely screw-driver carries to short tube (5) and locating, open packing gland (7), unload short tube (5), screw-driver cutter hub (10) and gate valve (4), at last that shutoff nail (2) and sealing of hole head (1) is integrally welded.With shutoff nail (2) and sealing of hole head (1) when being connected, the surface that can follow closely (2) in shutoff is coated with layer of metal binder or epoxy resin, to improve its sealing and corrosion resistance.The internal thread of aforesaid shutoff nail (2) and externally threaded direction opposite (promptly one is right-hand thread, and another is a left-hand thread).
Claims (4)
1, a kind ofly be used to infuse, the pipeline opening pressure testing device of gas transmission line, constitute by sealing of hole head (1), positioning ring (3), gate valve (4), short tube (5), packing (6), packing gland (7), sealing of hole head (1) is welded in pipeline and treats tapping, after it is characterized in that the perforate pressure testing, shutoff nail (2) is fixed in the interior shutoff perforate of sealing of hole head (1) by screw thread.
2,, it is characterized in that in the sealing of hole head (1) step being arranged, and internal thread is arranged in the step bottom according to the described pipeline perforate of claim pressure testing device.
3, pipeline perforate pressure testing device according to claim 1 is characterized in that an interior threaded hole is arranged at shutoff nail (2) top, and outside thread is arranged at top, and the internal and external threads direction is opposite.
