Abstract

The utility model discloses a pipeline expansion device which comprises a sealing element, and is characterized in that: the pipeline expansion device also comprises a parent tube, an extension tube and a honeycomb duct. One end of the parent tube is fixed with a connection flange disk and the external side of the other end is fixed with an outer ring clasp. One end of the extension tube is fixed with the connection flange disk, and the other end is sheathed at the external side of the parent tube with the outer ring clasp and is provided fixedly with an inner ring clasp to be matched with the outer ring clasp to form a scalable structure. The sealing element is arranged on the interface of the outer ring clasp and the inner ring clasp. The honeycomb duct is located via a circular step structure and is sheathed actively in the internal end of the extension tube with the flange disk and is easily dismantled. The parent tube, the extension tube and the honeycomb duct can be conical and are connected with conical pipes and devices. The device creates ample space for connectors in the pipeline system to well conduct work without damaging original pipelines or devices, which greatly reduces the amount of work and time, thereby enhancing work efficiency.

Description

The pipeline expansion device

Technical field

The utility model relates to a kind of pipe-line system, especially the connection between the pipe-line equipment.

Background technique

In present pipe-line equipment technology, certain equipment in pipe-line system, pipeline valve for example, when needing to change, particularly caliber is greater than the dismounting of 100mm pipe valve with install all difficult.Its reason is: it is very little with the space of leaving mounted valve and seal rubber pad thereof for that seal rubber pad is equipped with at the valve two ends.Usually be to cut off, together valve and steel pipe taken off, behind the valve of waiting to fix or finish changing, weld just with the electric weld handle scarfing again and finish with gas cutting handle and valve linking steel tubes, very bothersome.

The model utility content

The purpose of this utility model provides a kind of pipeline expansion device, can solve the deficiency that exists in the existing pipe-line equipment maintenance connection, increases work efficiency.

A kind of pipeline expansion device, it comprises Sealing, it is characterized in that also comprising:

Parent tube, an end of this substrate pipe is fixed with mounting flange, and the outside of the other end is fixed with outer latch closure;

Telescopic pipe, one end of this telescopic pipe is fixed with mounting flange, on the outside of the other end moving sleeve latch closure outside described parent tube has, and is fixed with inner becket, cooperate formation button Collapsible structure mutually with outer latch closure, described Sealing is located on the interface of outer latch closure and inner becket;

Honeycomb duct with the structural orientation of ring-shaped step, is actively set on the inner that telescopic pipe has flange plate, and can conveniently draws off.

The shape of described parent tube, telescopic pipe and honeycomb duct can be taper, connects conical pipeline and equipment.

The pipeline expansion device of said structure, parent tube and telescopic pipe constitute Collapsible structure, and honeycomb duct can conveniently draw off, and has created abundant space for the connection place in the pipe-line system, greatly facilitates the connection between the equipment in the pipe-line system.During use the pipeline expansion device is installed in a side of rapid wear pipe-line equipment, by this pipeline expansion device in maintenance or when changing this pipe-line equipment, enough operating spaces can be arranged, needn't destroy original pipeline or equipment, just can carry out work soon, greatly reduce workload and time, thereby improved working efficiency.Generally speaking this pipeline expansion device has following advantage:

(1) simple in structure, making and easy to use;

(2) flexible reliable with sealing flexibly;

(3) flexible distance is big, is very easy to the maintenance of pipe-line system;

(4) workload and the time of system maintenance have been reduced;

(5) in the little pipe-line system of negative pressure, low pressure or convergent-divergent amount, this device can be made used for expansion joint.

Embodiment

Below, in conjunction with the accompanying drawings this practicality newly is described further.

Shown in Figure 1, be the new sectional structure schematic representation of this practicality.In the drawings, parent tube 1 comprises latch closure 7 outside the outside of the parent tube flange plate 9 that is fixed on the left end outside and right-hand member; Telescopic pipe 3 comprises the parent tube flange plate 6 that is fixed on the left end outside and the inner becket 8 of right-hand member; Sealing 2 is located between described outer latch closure 7 and inner becket 8 opposing sides; Honeycomb duct 4 is actively set on the inboard that telescopic pipe 3 has flange plate 6 ends, and can conveniently draws off by the structural orientation of ring-shaped step 5.Wherein, the left side of telescopic pipe 3 is actively set on outside the right side of parent tube 1, and, as shown by arrows, can shrink left; Honeycomb duct 4 as shown by arrows, can make things convenient for to the right to draw off; The flange plate 6 and 9 of both sides is used for being fixedly connected with the system equipment of both sides.

Shown in Figure 2, be the cross-sectional schematic of the utility model cone structure.By among the figure as can be known, its structural principle is identical with Fig. 1's, different just parent tube 1a, telescopic pipe 3a are corresponding with honeycomb duct 4a pipe wherein is taper, are used to connect corresponding conical pipeline equipment.

Shown in Figure 3, be the sectional structure schematic representation that the utility model embodiment installs.In the drawings, pipeline expansion device of the present utility model, be installed in the left side of the valve 13 that goes wrong easily, and between the right side of pipeline 10, the connection place is respectively equipped with leakproof left side O-ring seal 11 and right O-ring seal 12, and the flange plate 6 by both sides and 9 and corresponding bolts connect with valve 13, pipeline 10 realization fixing seals.

Shown in Figure 4, be the sectional structure schematic representation of the utility model embodiment dismounting.By among the figure as can be known, pipeline expansion device of the present utility model is the dismounting of carrying out on the basis of Fig. 3, its witness's is that valve 13 is changed dismounting.At first, expansion device right side flange plate 6 is connected dismounting with bolt between the valve 13 left side flange plate; Telescopic pipe 3 being turned left pushes away again, and takes out honeycomb duct 4 simultaneously.Like this, between pipeline expansion device and valve 13, vacateed the space of a honeycomb duct 4 at least, for the dismounting and change of valve 13 has provided enough operating spaces.For reducing workload and time, increasing work efficiency provides reliable guarantee.
