Description

A kind of hole leakage blocking device

Technical field

The utility model belongs to closure field, more particularly, to a kind of hole leakage blocking device.

Background technique

All kinds of harmful influence media are in transport or storing process, and pipeline, tank body etc. by medium due to being washed away, burn into is old The influence of the factors such as change is easy to appear the problem of ontology leaks, needs to carry out repairing leak stopping in time, to reduce property loss, people Member's harm and environmental pollution etc..

In existing sealing technique, some use fastening-type blocking method, i.e., are tied up using stationary fixture, steel band or timber wedge etc. Mode makes it generate reaction force, is applied more than the pressure of medium itself in leakage position by modes such as part tightenings, real The method for blocking of existing final pressure balance.

It is timber wedge leak stopping with the immediate existing weaponry and equipment of the present invention, it may also be said to, the hole of novel straight tube (tank body) leakage Blocking equipment is to overcome itself existing defect on the basis of timber wedge leak stopping, and be subject to perfect optimization equipment.

Leak stoppage tool used by timber wedge leakage stopping technology is wooden leak stopping wedge.Applicable temperature is -70 DEG C to 100 DEG C, pressure Power -1.0MPa to 0.8MPa, timber wedge cannot complete leak-stopping, only by leakage control be micro- leakage, so can only temporarily use.Timber wedge The operation of leak stopping: being directed at leakage point for timber wedge, and righting is simultaneously forced into, with wooden mallet tap timber wedge, until timber wedge no longer wedge into for Only.Timber wedge leak stoppage tool has the characteristics that simply, quickly and effectively.

Using timber wedge leak stoppage tool, there is a problem that adapting to pressure it is relatively low, for irregular hole plugging effect compared with Difference.Because timber wedge leak stopping mode is the closure completed by the frictional force and expansive force of timber wedge to leakage point, sealing effect is inclined Difference.And timber wedge leak stopping is used, because wooden density is smaller, liquid medium has certain permeability to wood materials, thus Cause the effect blocked not ideal enough.When pressure medium is higher, timber wedge has the possibility being ejected, thus, cause plugging operations Failure.

Summary of the invention

In view of this, the utility model is directed to a kind of hole leakage blocking device, to solve, adaptability is poor, seals The technical problem of effect difference.

In order to achieve the above objectives, the technical solution of the utility model is achieved in that
