Abstract

A pipeline pressure-pumping shut-off device is composed of a shut-off screw cap, a shut-off screw rod, a seal cap, a seal pressure lid, an open cirque expansion bush and a taper rod. One end of the shut-off screw rod is connected with the taper rod and the two form an integral structure, and the other end of the shut-off screw rod is fixed spirally with the shut-off screw cap. A taper placket is arranged at one end of the open cirque expansion bush and is matched with the taper rod. The open cirque expansion bush is sleeved and arranged via the taper placket onto the taper rod. The taper rod together with the open cirque expansion bush is encased into a pipeline flange or a pipeline. The seal pressure lid is spirally arranged onto the shut-off screw rod, and is covered on the flanged mouth of the pipeline flange or the nozzle of the pipeline. The seal cap is spirally arranged onto the shut-off screw rod. One end of the seal cap is connected with the seal pressure lid, and the other end of seal cap is connected with the shut-off screw cap; thereby forming the pipeline pressure-pumping shut-off device. The utility model has the advantages of small body, no leakage, and easy operation and disassembly, which greatly improves the working efficiency.

Description

A kind of pipe is suppressed blocking device
(1) technical field
The utility model relates to a kind of pipe and suppresses blocking device, the blocking device when particularly relating to a kind of single tube road, multitube road and system and suppressing.
(2) background technique
In the shipbuilding process, it is a requisite work for inspection that single tube road, multitube road and system suppress.Former when carrying out the pipe bulge test, all adopt the taper stopper to seal, but the tube mouth irregularity that has, stopper shutoff difficulty need be by the knocking of external force during stopper mounting or dismounting simultaneously, and narrow and small place, space is difficult for by external force, constructional difficulties.Shutoff ubiquity leakage phenomenon in this way, the duplication of labour is too much, wastes a large amount of manpowers and the energy, and working efficiency is low.
(3) summary of the invention
The technical problems to be solved in the utility model, it is little, convenient and practical to provide a kind of volume, can solve leakage phenomenon when suppressing, and satisfies a kind of pipe of test requirements document and suppresses blocking device.
The technological scheme that adopts is:
A kind of pipe is suppressed blocking device, comprises shutoff nut, shutoff screw rod, sealed cap, sealing gland, opening expansion set, cone body rod.One end of described shutoff screw rod connects cone body rod and is an overall structure, and the other end with screw thread and shutoff nut spinning together.Opening expansion set one end is set as the tapered opening that is complementary with cone body rod, and the opening expansion set is sleeved on the cone body rod with its taper mouth, and cone body rod is packed in pipeline flange or the pipe together with the opening expansion set.Sealing gland with the screw thread spinning on the shutoff screw rod, and lid is contained on the mouth of pipe of the flange mouth of pipeline flange or pipe, and on the shutoff screw rod, the one end is connected with sealing gland sealed cap with the screw thread spinning, its the other end is connected with the shutoff nut, constitutes a kind of pipe and suppresses blocking device.
Above-mentioned sealing gland is equiped with seal ring, is pressed on the mouth of pipe sealing on every side of the flange mouth or the pipe of pipeline flange with sealing gland.
Above-mentioned sealed cap is equiped with seal ring, is pressed on the sealing gland with sealed cap to seal.
Packing ring is equipped with in the joint between above-mentioned sealed cap and the shutoff nut.
The utility model volume is little, simple to operate, installing/dismounting is quick, does not have to leak, and has improved working efficiency greatly.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
A kind of pipe is suppressed blocking device, comprises shutoff nut 1, shutoff screw rod 2, sealed cap 4, sealing gland 8, opening expansion set 7, cone body rod 10.One end of described shutoff screw rod 2 connects cone body rod 10 and is an overall structure, and the other end with screw thread and shutoff nut 1 spinning together.Opening expansion set 7 one ends are set as the tapered opening that is complementary with cone body rod 10, and opening expansion set 7 is sleeved on the cone body rod 10 with its taper mouth, with cone body rod 10 together with opening expansion set 7 pipeline flange 11 of packing into.Sealing gland 8 with the screw thread spinning on shutoff screw rod 2, and lid is contained on the flange mouth of pipeline flange 11, sealed cap 4 with the screw thread spinning on shutoff screw rod 2, the one end is connected with sealing gland 8, its the other end is connected with shutoff nut 1, screwing hermetic gland 8 and sealed cap 4, the seal ring 5 compacted sealings of the seal ring 6 of sealing gland 8 installings and sealed cap 4 installings, the packing ring 3 that rubber asbestos plate is made also is equipped with in the joint between sealed cap 4 and shutoff nut 1.With spanner the terminal nut 9 on the shutoff nut 1 is screwed, can realize managing interior shutoff, the pipe external sealed constitutes a kind of pipe and suppresses blocking device.
Working principle:
Cone body rod 10 is put into pipeline flange 11 or pipe together with opening expansion set 7, screw shutoff screw rod 2, this moment, cone body rod 10 in pipeline flange 11 or pipe rose gradually, and opening expansion set 7 is subjected to cone body rod 10 to push also swellings gradually, in pipeline flange or the pipe just by shutoff.Screwing hermetic gland 8 and sealed cap 4 compress seal ring 6 and seal ring 5 again, and whole mouth of pipe outside is sealed.Air feed is suppressed in pipeline, and pressure is transferred to required pressure testing value, checks whether sealing part has leakage, and if any leaking as long as with spanner terminal nut 9 turns on the shutoff nut 1 are compressed, leakage phenomenon will be resolved, and smooth implementation is suppressed.
