Description
Technical field
The present invention relates to leakage stopping technology field, and in particular to a kind of Quick mechanical formula hydraulic pressure device for plugging.
Background technology
In the industrial production, many raw materials conveying and accumulating be all to be realized by pipeline or container.These pipelines or
The material of container mainly has stainless steel, plastics, glass etc. according to purposes and the difference of medium.The form of raw material is of all kinds, has
Oil, the ethanol, gaseous natural gas, hydrogen, oxygen etc. of liquid, these raw materials often have certain danger (inflammable easy
It is quick-fried or there is corrosivity or poisonous), once it is hardly imaginable that leakage consequence occurs.But reality production in, no matter how good pipe
Road or container are all inevitable in the presence of the risk ruptured in use, so as to cause raw material leakage, production pause etc. sternly
Weight consequence.
In the prior art, the common method of disposal of piping failure is carried out to close upstream and downstream valve immediately after emptying pipeline
Change.This emergency processing method is often time-consuming longer, and less efficient, unplanned shut-down can also cause larger damage to factory
Lose.There is a method in which it is exactly that breakage is blocked using device for plugging, Chinese patent CN206268707U discloses one
The leak stopping sleeve pipe of kind ring-type, although various sizes of pipeline can be adapted to by adjusting inner ring body, its adjustable range mistake
In narrow and be bonded defective tightness with pipeline, limited to its application.Chinese patent CN206280661U discloses one kind
Valve body micropore leak stoppers, but the equipment needs external power supply to vacuumize, being doomed it can not be carried out using building site in the wild
Construction operation.Chinese patent CN206310154U discloses a kind of Pipe leakage stopper, pipe of the device to conveying liquid medium
Also need to carry out pressure release thorn leak source repair welding after pipeline leakage stopping.Chinese patent CN206329859U discloses a kind of Pipe leakage stopper,
By the principle expanded with heat and contract with cold, using the expansion plugging leak source of leakage stopping block, this requires that leak source is larger and leakage stopping block needs to insert
In pipeline.Chinese patent CN106958715A discloses a kind of natural gas line on-line production fast blockage equipment, passes through belt tensioner
Pressure bowl and clay are fixed at piping failure, remove leak stoppers again after clay solidification, the method for blocking is complex also
Clay need to be coordinated to be used together, easily pollute the medium of conveying in pipeline, and for larger leak source plugging effect and bad,
This contact of external pressure bowl with pipeline is not close, easy residual air, influences the persistence of closure.
The present invention after current all device for plugging, with reference to each advantage, develops a kind of Novel machine in comprehensive study
Tool formula hydraulic pressure device for plugging, the sealing gasket of the device be bondeds closely with pipeline or closure face, be suitable for different size of caliber with
Leak source, closure process operation is simple, and without additionaling power source, small volume is easy to carry, and the field condition that is particularly suitable for use in closure is made
Industry.

Arm is connected with handwheel, and the other end of main shaft is connected with outer casing base and plugging block respectively, and spring and spacing is socketed with main shaft
Nut, drag hook and drag-line chuck have been movably connected with tension arm both ends, and the plugging block includes shell, briquetting, leather bag support
Disk, leather bag and rubber seal.
According to such scheme, the mounting seat being attached thereto is also respectively provided with plugging block both sides, is set in mounting seat
Having can 90 ° of handle rotated.
According to such scheme, the structure of leather bag is the block rubber with concave shape, and the leather bag passes through leather bag pallet., bolt
It is fixedly connected with briquetting, the briquetting is fixedly connected by bolt with outer casing base, and the rubber seal is arranged on leather bag week
Enclose and be connected with shell, be thus internally formed a cavity for being available for leather bag closure deformation in plugging block.Filled in the cavity
Hydraulic oil.Pressure is uniform after hydraulic oil can ensure leather bag stress, preferably presses close to block curved surface.
According to such scheme, the drag-line chuck is fixed by locking claw or unclamps drag-line.
Compared with prior art, beneficial effects of the present invention are：(1) structure of plugging device is optimized, is especially blocked
The structure of block so that whether contact of the leather bag with blocking face is even closer, no matter manage interior medium and pressurize and leak source size,
There is more preferable plugging effect, while avoid using pollution of the clay to pipeline internal medium；(2) device for plugging can be used for sealing
Stifled plane, pipeline or tank surface and curved surface, can block the medium within 8MPa, generally left in 3-5min the time required to closure
It is right；(3) structure is relatively simple, easy to carry, is particularly suitable for factory or field condition operation；(4) one is i.e. operable, without
Stop work and production, do not influence to produce, efficiency high.
