Description
Technical field
The utility model is the four-way of the small-bore gas pipeline perforate shutoff when being used for the online press and open holes shutoff of the small-bore gas pipeline of high pressure, relates to the pipe-line system technical field.
Background technique
Gas pipeline need be drawn numerous branch pipelines from main pipeline 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.Present shutoff operation in cartridge type four-way of shutoff place elder generation overcoat and welding, is inserted by the blocking device enforcement shutoff of exerting pressure with block head after the perforate from four-way.But present four-way since need with implemented welding by the shutoff pipe, so only be suitable for the branch pipeline of thick tube wall.And, then do not have the four-way that is suitable for for the perforate shutoff of light wall pipe wall branch pipeline.
The model utility content
The purpose of this utility model is the four-way of safe, the tight small-bore gas pipeline perforate shutoff of the online press and open holes shutoff of the design small-bore gas pipeline of a kind of high pressure.
The four-way of present small-bore gas pipeline perforate shutoff comprises that four-way upper shell 5, four-way lower shell body 8, nut cap 1, plug are stifled 2, back-up ring 3 and seal ring 4, the following logical sealing that communicates with four-way lower shell body 8 middle parts, lead to upper shed on communicating with four-way upper shell middle part, and it is stifled 2 to be screwed into the plug that has back-up ring 3 and seal ring 4 by screw thread, and upward logical top is screwed into nut cap 1 cap seal by outside thread.The problem that the utility model can not be implemented to weld by the shutoff pipe at thin-walled, the four-way of the bonding replacement welding of a kind of usefulness is proposed, its structure as shown in Figure 1 and Figure 2, be exactly two half-covering tubes 7 of cover and on by the shutoff pipe with two seam welding, four-way upper shell 5 is placed in sleeve pipe 7 outer involutory back welding with four-way lower shell body 8, annotate at the sleeve pipe 7 of the non-welding ends of four-way and between and add that sealer is close to be pressed into two and half glands 6 after bonding again by shutoff pipe and four-way, at last again with sealer with gland 6 with close bonding by shutoff pipe and sleeve pipe 7.Wherein, sleeve pipe 7 (seeing Fig. 3, Fig. 4) is from axially being divided into two semicanals, it after involutory the big steel pipe of one side little another side external diameter of external diameter, the internal diameter of big external diameter end equals or is slightly larger than the external diameter of gland 6, to be pressed into gland 6, the internal diameter of path section equals or is slightly larger than by the external diameter of shutoff pipe 9, and has for the groove that welds in the outside of two semicanals to joint close.Gland 6 (seeing Fig. 5, Fig. 6) is from axially being divided into two semicanals, the involutory back isometrical lengths of steel pipes that is.And sealer is a kind of high voltage bearing double-component glue.In order to be convenient to change pipeline section at four-way osculum place, there is step non-welding termination at four-way upper shell 5 and four-way lower shell body 8, and groove (seeing Fig. 7, Fig. 8) is arranged on the quadruple board platform limit, so that when changing, change pipe box behind thin termination, weld with the quadruple board platform rank by the shutoff pipe.When carrying out the perforate shutoff with this four-way, earlier two half block sleeve pipes 7 are enclosed within and are welded into homogeneous tube on the shutoff pipe, its outer four-way upper shell 5 and four-way lower shell body 8 of putting again, the involutory integral body that is welded into, trumpet end is enclosed within by on the boss of shutoff pipe root, outer edge and main pipeline contacting point welded seal at trumpet end, sleeve pipe 7 is bonding with four-way upper shell 5 and 8 sealings of four-way lower shell body at the non-welding ends of four-way by high pressure sealing glue, and be pressed into gland 6, by sealer that the clearance seal between gland 6 and sleeve pipe 7 and four-way upper shell 5, the four-way lower shell body 8 is bonding again.So structure do not weld on by the shutoff pipe, and all sealing-in is tight on four-way is enclosed within by two of the shutoff pipe logical directions, thereby can have been carried out perforate shutoff operation.

Embodiment
Embodiment. embodiment of the present utility model is described and this four-way is further described with this embodiment.This example is that Φ 34 * 3mm branch pipeline is carried out the used four-way of perforate shutoff, pipeline working pressure 10.0Mpa.The structure of this four-way such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, shown in Figure 8.Two half-covering tubes 7 of cover and on by the shutoff pipe with two seam welding, four-way upper shell 5 is placed in sleeve pipe 7 outer involutory back welding with four-way lower shell body 8, annotate at the sleeve pipe 7 of the non-welding ends of four-way and between and add that sealer is close to be pressed into two and half glands 6 after bonding again by shutoff pipe and four-way, at last again with sealer with gland 6 with close bonding by shutoff pipe and sleeve pipe 7.In order to be convenient to change pipeline section, in the non-welding termination of four-way upper shell 5 and four-way lower shell body 8 step to be arranged, and on the quadruple board platform limit groove is arranged (seeing Fig. 7, Fig. 8) at four-way osculum place.Wherein, sleeve pipe 7 (seeing Fig. 3, Fig. 4) is from axially being divided into two semicanals, it after involutory the big steel pipe of one side little another side external diameter of external diameter, the internal diameter of big external diameter end equals or is slightly larger than the external diameter of gland 6, to be pressed into gland 6, the internal diameter of path section equals or is slightly larger than by the external diameter of shutoff pipe 9, and has for the groove that welds in the outside of two semicanals to joint close.Gland 6 (seeing Fig. 5, Fig. 6) is from axially being divided into two semicanals, the involutory back isometrical lengths of steel pipes that is.
Its key dimension is: the long 200mm of four-way substantially horizontal after involutory, the long 53mm of trumpet end, mouthful Φ 146mm, the non-welding ends external diameter 87mm that trumpet end is relative, internal diameter 56mm, platform external diameter 70mm; The high 238mm of Vertical direction, the thinnest 40mm of place in four-way middle part; Sleeve pipe 7 big outer diameter section Φ 56mm after involutory, long 57mm, large diameter Φ 46mm, long 35mm, small outer diameter section Φ 40mm, long 73mm, internal diameter Φ 34mm, long 103mm, big or small external diameter changeover portion 8mm, length overall 138mm; Be the short steel pipes of Φ 44mm, internal diameter 36mm behind 6 liang of semi-involutions of gland.Before implementing the perforate shutoff, earlier two half-covering tubes 7 are enclosed within by on the shutoff pipe, two seam crossing weldings, be enclosed within four-way upper shell 5 and four-way lower shell body 8 outside the sleeve pipe 7 involutory, to its seam welding, horn mouth is enclosed within by after on the boss of shutoff pipe and main line pipe joint, horn mouth and the welding of main line pipe, in non-welding ends usefulness sealer sprue bushing 7 and by the gap between shutoff pipe, the four-way, with they close seals, be pressed into two half glands 6 at sleeve pipe 7 and between by the shutoff pipe, at last again with sealer with gland 6 with sleeve pipe 7, by the close seal of shutoff pipe.Here used sealer is a high pressure double-component glue.So just can begin perforate and shutoff operation, after shutoff is good, change by the shutoff pipe, can cut away old pipe as need, new pipe box the four-way level to non-welding ends on, weld with step.Prop up enforcement perforate shutoff operation on the spool with this four-way at the Φ 34 * 3mm of the main line gas pipeline of working pressure 10Mpa, after shutoff, replace tubes were finished, through surveying, the sealing of this four-way was tight, and no Vent leaks, safely, reliably, and processing ease.
As seen, though the utility model has been used two in addition parts more, processing ease, sealing is tight, and safety, reliable has solved the difficult problem that spool perforate shutoff is propped up in the thin-walled gas transmission, and is extremely with practical value.
