Description

A kind of pipe stopper

Technical field

The utility model is related to pipe technology field, and in particular to a kind of pipe stopper.

Background technology

Generally require to block the mouth of pipe using plug when overhauling pipeline, traditional plug is next only by compressing Stifled tight purpose is reached, but is just inconvenient overhauling when end needs to take out plug, or even needs to take after plug is crushed Go out, many plugs can only be intended for single use, greatly increase the cost of overhaul, and it is difficult complete that fragment, which is, under this particular surroundings of pipeline Portion takes out, and fragment residual produces certain potential safety hazard in the duct.

The content of the invention

The purpose of this utility model, which is to provide one kind, to be used for multiple times, convenient to take out, cost-effective, will not produce residual broken The pipe stopper minced.

To achieve these goals, a kind of technical scheme of the present utility model is：A kind of pipe stopper, its improvement is： With body, upper tabletting, lower sheeting, screw bolt and nut, the body is in taper type, the screw bolt passes lower sheeting, sheet Body and upper tabletting, and fixed by nut, the cap portion of the bolt is located at the miner diameter end of body, and the nut is located at the big footpath of body End, the body is elastomeric material.

In the above-mentioned technical solutions, the material of the body is rubber or silica gel.

In the above-mentioned technical solutions, the end of thread end face of the bolt has the inner bolt hole of axial direction.

In the above-mentioned technical solutions, the bigger diameter end external diameter Φ of the body₁With the external diameter Φ of upper tabletting₂Meet relational expression 0.5 Φ₁≤Φ₂＜ Φ₁, the miner diameter end external diameter Φ of the body₃With the external diameter Φ of lower sheeting₄Meet the Φ of relational expression 0.5₃≤Φ₄＜ Φ₃。

To achieve these goals, another technical scheme of the present utility model is：A kind of pipe stopper, with body, Upper tabletting, lower sheeting, screw bolt and nut, the body in cylinder, and on the outer peripheral face of body have some annular grooves and Annular boss, the screw bolt passes lower sheeting, body and upper tabletting, and fixed by nut, the body is elastomeric material.

In the above-mentioned technical solutions, the cross section of the annular groove is rectangular channel or dovetail groove or arc-shaped slot.

In the above-mentioned technical solutions, there are two annular grooves and three annular protrusions on the body.

In the above-mentioned technical solutions, the cylinder external diameter Φ of the body₅, upper tabletting external diameter Φ₆With the external diameter of lower sheeting Φ₇Meet the Φ of relational expression 0.5₅≤Φ₆＜ Φ₅, 0.5 Φ₅≤Φ₇＜ Φ₅。

Benefit of the present utility model is：, can be by tightening due to body, upper tabletting, lower sheeting, screw bolt and nut Nut drives upper tabletting and lower sheeting to carry out the extruding of axial direction to body, body is produced the mesh for being radially expanded and reaching stifled tight pipeline , it and need to only unscrew nut when taking out, release axial thrust, body not reflation and volume contraction can easily take Go out, plug can be used for multiple times, not only greatly save cost, and need not be taken out by the way of destruction and residual will not be produced Fragment, it is to avoid potential safety hazard.

Embodiment

Below in conjunction with accompanying drawing and the embodiment provided, the utility model is further described.

Embodiment one：

As shown in Fig. 1 ~ 3, a kind of pipe stopper is described with body 1, upper tabletting 2, lower sheeting 3, bolt 4 and nut 5 Body 1 is in taper type, and the bolt 4 sequentially passes through lower sheeting 3, body 1 and upper tabletting 2, and is fixed by nut 5, the bolt 4 Cap portion be located at body 1 miner diameter end, the nut 5 be located at body 1 bigger diameter end.

The body 1 is elastomeric material, and the material of the body 1 is rubber or silica gel.

The end of thread end face of the bolt 4 has the inner bolt hole 4-1 of axial direction, when the excessively thick plug of service conduits slips into pipeline When, the inner bolt hole of bolt 4 can be screwed into instrument, plug is extracted after coordinating with inner bolt hole.

As shown in Figure 1, 2, the bigger diameter end external diameter Φ of the body 1₁With the external diameter Φ of upper tabletting 2₂Meet the Φ of relational expression 0.5₁ ≤Φ₂＜ Φ₁, the miner diameter end external diameter Φ of the body 1₃With the external diameter Φ of lower sheeting 3₄Meet the Φ of relational expression 0.5₃≤Φ₄＜ Φ₃。

Embodiment two：

As shown in Fig. 4 ~ 6, with body 1, upper tabletting 2, lower sheeting 3, bolt 4 and nut 5, the body 1 is in cylinder, And there are some annular groove 1-1 and annular boss 1-2 on the outer peripheral face of body 1, the bolt 4 sequentially passes through lower sheeting 3, sheet Body 1 and upper tabletting 2, and fixed by nut 5.

The end of thread end face of the bolt 4 has the inner bolt hole 4-1 of axial direction, when the excessively thick plug of service conduits slips into pipeline When, the inner bolt hole 4-1 of bolt 4 can be screwed into instrument, plug is extracted after coordinating with inner bolt hole.
