Abstract

The utility model relates to a pipe plug component used for plugging a pipe hole on a gas pipeline. The pipe plug component comprises a nut, a gasket with a convex end face, and a T-shaped main body. The pipe plug component is characterized in that: the pipe plug component also comprises a downward cone-shaped sealing ring sleeved on a vertical bar of the 'T'-shaped main body. The material of the sealing ring is gas-resistant rubber. The convex end face of the gasket is pressed on the sealing ring downwards, and the convex end face of the gasket and an upper end surface of the sealing ring are in male and female connection. The pipe plug component has the advantages of simple structure, convenient operation and low cost, and is not limited by thickness of the pipe wall of the pipeline and the shape of the pipe hole in order to ensure to realize good tightness in pipe hole plugging.

Description

A kind of pipe plug spare

Technical field

The utility model relates to the mechanical interface of not getting angry, and relates in particular to a kind of pipe plug spare that is used for the pore shutoff on the gas pipeline.

Background technique

Now, generally use steel pipe or ductile iron pipe in the gas industry, though mechanical strength height such as withstand voltage, the impact resistance of steel pipe, cast iron tube still exist because the leakage hidden danger that material is not good or construction wrong caused as fuel gas transportation pipeline.The gas leakage of the gas pipeline which kind of reason is drawn all is not allow the serious accident that takes place, therefore leaks in case take place, and must rush to repair fast and effectively.Yet at present, existing gas pipeline repairing accessory user cost height, poor practicability, therefore, with regard to present industry present situation, what be short of most is ripe effectively damage repair technology and handy repairing means and repairing parts.

The model utility content

In order to overcome the problems referred to above, the utility model aims to provide a kind of pipe plug spare, and is simple with implementation structure, easy to operate, and cost is low, is not subjected to the restriction of pipe wall wall thickness and pore shape, makes the pore shutoff reach the purpose of good leakproofness.

A kind of pipe plug spare described in the utility model, be used for the pore shutoff on the gas pipeline, comprise that nut, an end face are the packing ring of convex surface, T type main body, handle, is characterized in that: it also comprises a downward tapered seal ring that is set on the T type main body montant.

In above-mentioned a kind of pipe plug spare, the material of described seal ring is the rubber of anti-the combustion gas.

In above-mentioned a kind of pipe plug spare, described packing ring convex surface is put on described seal ring to pressing down, and the convex surface of described packing ring cooperates with the upper-end surface negative and positive of described seal ring.

In above-mentioned a kind of pipe plug spare, the montant surface of described T type main body has additional screw thread.

Owing to adopted above-mentioned technical solution, the utility model is to the shape of seal ring, the design of material, and set up screw thread on the montant surface of T type main body, and realized not being subjected to the restriction of pipe wall wall thickness and pore shape, make the pore shutoff reach the purpose of good leakproofness.In addition, the montant of T type main body connects handle, makes fitting operation convenient and swift, also have simultaneously simple in structure, low cost and other advantages.

Description of drawings

Fig. 1 is the structural representation that the utility model pipe plug spare is installed in gas pipeline pore place.

Embodiment

As shown in Figure 1, the utility model, promptly a kind of pipe plug spare, comprise that nut 1, an end face are the packing ring 2 of convex surface, T type main body 3, seal ring 4, handle 5, wherein seal ring 4 is set on the montant 31 of T type main body 3, and tapered downwards, and its material is the rubber of anti-the combustion gas.

Packing ring 2 convex surfaces are put on seal ring 4 to pressing down, and the convex surface of packing ring 2 cooperates with the upper-end surface negative and positive of seal ring 4.

Montant 31 surfaces of T type main body 3 have additional screw thread.

When the utility model is installed in the pore 61 of gas pipeline 6, can earlier nut 1, packing ring 2, seal ring 4 be inserted in handle 5 successively, handle 5 be screwed in counterclockwise in the silk mouthful on montant 31 tops of T type main bodys 3 and screw; Again T type main body 3 is inserted in the pipeline 6 along pore 61, use handle 5 that T type main body 3 is upwards pulled to vertically, the cross bar 32 of T type main body 3 stays in pore 61, in pore 61, put into seal ring 4, packing ring 2 successively, with the cross bar 32 2 pin adjustment of T type main body 3 and the parallel axes of pipeline 6 (being the highest position of pipeline 6); Screw nut 1 at last, packing ring 2 is pressed on the seal ring 4, seal ring 4 shutoff are in pore 61.After finishing above-mentioned installation, the handle 5 of can also dextrorotation loosing one's grip is removed.

In sum, the utility model is to the shape of seal ring, the design of material, and sets up screw mouth on the montant surface of T type main body, realized not being subjected to the restriction of pipe wall wall thickness and pore shape, makes the pore shutoff reach the purpose of good leakproofness.In addition, the montant of T type main body connects handle, makes fitting operation convenient and swift, also have simultaneously simple in structure, low cost and other advantages.

Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
