Abstract
The utility model discloses a safe and effective cut-off device used on a pipeline. The cut-off device used on the pipeline comprises a rubber pneumatic tire, a drainage pipe, a supporting pipe, a baffle, a check ring, frame plates and bolts, wherein the check ring is welded at one end of the drainage pipe, the supporting pipe is welded on the outer edge of the check ring, the frame plates are welded on the outer surface of the middle section of the supporting pipe, the bolts are welded on the inner wall of the other end of the supporting pipe, the bolts are evenly distributed on the inner wall of the supporting pipe, the baffle is in screw connection with the bolts in an integral mode, the rubber pneumatic tire is arranged on the drainage pipe between the baffle and the check ring in a sleeved mode, and a charging connector opening is formed in the inner wall of the drainage pipe. According to the cut-off device used on the pipeline, a structure with the rubber pneumatic tire matched with the drainage pipe is adopted, the cut-off function is achieved by means of the rubber pneumatic tire, accumulated water coming from the inflow direction is discharged through the drainage pipe, and therefore accumulated water generated during the cut-off is not excessive, and potential safety hazards of constructors are avoided.
Description
Technical field
The utility model relates to the cut-off device that uses in a kind of pipeline.
Background technique
In such as pipeline constructions such as pipe network improvings, usually in pipeline, carry out work, owing to the restriction of all objective condition, can have the ponding of certain pressure in the pipeline, and the time of constructing in the pipeline is usually ofer short duration.Traditional method is to wait in the pipeline that water nature earial drainage is complete just can enter construction afterwards, can prolong the engineering time like this, and construction unit is produced normally, lives and cause larger impact.Be the employing air tyre with the immediate prior art of the utility model, by the volumetric expansion of air tyre that the complete complete shutoff of pipeline section is dead, reach the purpose of damming.But often can run into the pipeline that to dam during construction and carry out the short time construction; do not need again the situation of cutting off the water for a long time; and above-mentioned correlation technique is that whole pipe plugging is dead; after ponding is more; air tyre can bear larger pressure; after the friction of hydraulic pressure greater than air tyre and tube wall, the problem that shutoff was lost efficacy can appear, bring potential safety hazard to workmen in the pipeline.
Summary of the invention
The purpose of this utility model provides a kind of safely and effectively pipe flow blocking device.
The technical solution of the utility model is: comprise rubber filling gas tyre, also comprise drainage tube, support tube, baffle plate, back-up ring, frame plate and bolt, drainage tube one end is welded with back-up ring, the back-up ring outer rim is welded with support tube, and support tube stage casing outer surface is welded with frame plate, and support tube the other end inwall is welded with bolt, bolt is along the inner wall even distribution of support tube, baffle plate and bolt are spirally connected and are integrated, and rubber filling gas tyre is enclosed within on the drainage tube between baffle plate and the back-up ring, and the drainage tube inwall is provided with the charging air inlet opening.
Because the structure that adopts rubber filling gas tyre to match with drainage tube in the utility model relies on closely cooperating of rubber filling gas tyre and inner-walls of duct, the dam effect of water proof of realization.When the pipeline internal water accumulation reaches a certain amount of, derive by drainage tube, make the ponding that produces when damming can be not too much, can not cause potential safety hazard to the workmen.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but does not consist of any restriction of the present utility model.Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises rubber filling gas tyre 7, drainage tube 1, support tube 3, baffle plate 2, back-up ring 5, frame plate 4 and bolt 6, drainage tube 1 one ends are welded with back-up ring 5, back-up ring 5 outer rims are welded with support tube 3, support tube 3 stage casing outer surfaces are welded with frame plate 4, support tube 3 the other end inwalls are welded with bolt 6, bolt 6 is along the inner wall even distribution of support tube 3, baffle plate 2 is spirally connected with bolt 6 and is integrated, rubber filling gas tyre 7 is enclosed within on the drainage tube 1 between baffle plate 2 and the back-up ring 5, and drainage tube 1 inwall is provided with the charging air inlet opening.During use, charging air inlet on the rubber filling gas tyre 7 is passed drainage tube 1 inwall, then inflate, rubber filling gas tyre 7 outer rims are contacted with inner-walls of duct, and when inflation was finished, rubber filling gas tyre 7 was close to inner-walls of duct, reach the purpose of damming, the water of inflow direction is blocked by rubber filling gas tyre 7, and the water of the direction of leaking water drains naturally, creates conditions to pipeline construction.
