Abstract
The utility model relates to a plug end for plugging of small caliber gas delivery pipe opening matched with online pressurized opening plug device of small caliber gas delivery pipe relating to pipe system technical field. The utility model consists of a plug rod (1) , a sealing sleeve (2), a compression seat (6) and a screw (5). The sealing sleeve (2) is slipped outside the plug end of the plug rod (1). Wherein, one end of the sealing sleeve (2) is clamped at the coarse-pitch snap ring at the middle part of plug rod (1). Another end of the sealing sleeve (2) is contacted with compression seat (9) for locating, which is slipped on the end socket of plug rod (1) and is cooperated and located by the internal threads and the screw (5) of the end socked of plug rod (1) . The plug end has advantages of tight plug without any leakage, long plug duration and long life, so the invention can be used in the plugging of pipeline with work pressure up to 10Mpa.
Description
Technical field
The utility model is the block head of the supporting small-bore pipeline perforate shutoff of the online press and open holes blocking device of a kind of and small-bore gas pipeline.Relate to the pipe-line system technical field.
Background technique
Gas pipeline is because its user is numerous, and these small-bore branch pipelines usually can need be done the shutoff processing operation of circuit because of a variety of causes.During the shutoff operation,, from four-way, insert by the blocking device enforcement shutoff of exerting pressure with block head after the perforate in cartridge type four-way of shutoff place elder generation overcoat and weldering or bonding.But present block head only is applicable to low pressure pipeline owing to structure problem, and shutoff imprecision, short deficiency of shutoff time are arranged.
The model utility content
The purpose of this utility model is the block head of the tight and small-bore pipeline perforate shutoff that the shutoff time is long of the shutoff of the design small-bore gas pipeline of a kind of high pressure online press and open holes shutoff.
The utility model proposes a kind of new design at the deficiencies in the prior art, and its structure as shown in Figure 1.It mainly is made up of shutoff bar 1, stuffing box gland 2, wedge 6 and screw 5.Be stuck in the Huan Kachu on particle size limit, shutoff bar 1 middle part at the shutoff end overcoat stuffing box gland 2 of shutoff bar 1, the other end of stuffing box gland 2 be placed in shutoff bar 1 termination and cooperate the wedge 6 of location to contact the location with screw 5 by the internal thread of shutoff bar 1 termination.Shutoff bar 1 (see figure 2) wherein is the round bar that two ends are thin, the middle part is thick, with the center, termination of wedge 6 connecting ends inner bolt hole is arranged, and connects the shape of the thin end of blocking device power end, decides on the concrete structure of blocking device.Stuffing box gland 2 (see figure 3)s are tubulose, are loose fit with shutoff bar 1, and its material is a teflon.Wedge 6 (see figure 4)s are that an end opening, the other end plug center have the round short tube that makes 1 hole of passing of shutoff bar.After shutoff bar 1 and wedge 6 connecting ends are inserted in stuffing box gland 2 and wedge 6 successively, be screwed in the inner bolt hole of shutoff bar 1 termination by the interior hexagonal left-handed screw 5 that puts spring pad 4 and pad 3, wedge 6 is positioned on the shutoff bar 1.The external diameter of the pad 3 here is more smaller than the internal diameter of wedge 6, and when 1 on shutoff operation shutoff bar was pressed to wedge 6,1 on shutoff bar and pad 3 can slide wedge 6 in, and the while crush seal overlaps 2, makes stuffing box gland 2 bulges, tightly with the pipe plugging of perforate.

Embodiment
Embodiment. with this example embodiment of the present utility model is described.This example is that its structure as shown in Figure 1 to the block head of the gas pipeline perforate shutoff of Φ 34mm, working pressure 10Mpa.Shutoff bar 1 wherein as shown in Figure 2, its physical dimension is: length overall 190mm connects wedge 6 segment length 90mm, Φ 18mm, middle part big outer diameter section long 59mm, Φ 32mm has the outside thread of M32 * 3, at connection wedge 6 one ends large diameter ring card is arranged, be cut into the inclined to one side shape of thick 12.6mm at connection 7.5mm place, blocking device termination, connect blocking device segment length 41mm, Φ 12.6mm, laterally make a call to the hole of a Φ 3mm apart from outer end 20mm place, this is for cooperating the used blocking device of this shutoff custom-designed; The shape of stuffing box gland 2 as shown in Figure 3, its physical dimension is: long 79mm, external diameter 37.5mm, internal diameter 18.8mm, material is a teflon; Pad 3 external diameter 24.5mm, internal diameter 10.5mm, thick 3mm; Screw 5 is a hexagonal left-handed screw in the M10, nut Φ 16mm, length overall 35mm, the long 25mm of screw thread; Wedge 6 shapes as shown in Figure 4, external diameter 35mm, internal diameter 25mm, plug end center hole is Φ 18mm, long 44.5mm.This block head is through the on-the-spot use of transfering natural gas from the west to the east pipeline pressure inlet tube (pipeline working pressure 10Mpa), and shutoff is tight, does not have to leak, and the time of shutoff can be grown arbitrarily and still not leak, and can use repeatedly, and the life-span is long, and is simple, convenient during the shutoff operation.
As seen, the utility model has overcome the deficiency of existing block head, does not make the online press and open holes shutoff of small-bore gas pipeline tightly, do not leak, the shutoff time lengthening, and the block head life-span is long, and can use repeatedly, applicable to the shutoff up to 10Mpa pipeline working pressure.
