Description
Technical field
It the utility model is related to a kind of duct closing type device, category Oil ＆ Gas Storage gathering line maintenance tool field.
Background technology
In order to meet that the field such as the needs remotely conveyed, petrochemical industry, gas industry generally conveys oil, gas by pipeline
Deng medium.Under self-corrosion, the effect of artificial or external force, pipeline can leak, it is necessary to carry out mending-leakage to pipeline in time and rob
Repair or connect head plugging construction.Due to can not thoroughly exclude, replacing the residual dielectric inside pipeline, the band fire in even head plugging construction
Lighting-blast casualty easily occurs for operation, causes potential safety hazard.At present, even head plugging construction seals frequently with nitrogen displacement method and butter wall
Stifled method, if nitrogen displacement method running cost is high, complex procedures and generation Lighting-blast casualty need to re-start nitrogen displacement；Butter wall seals
Stifled rule blocking time early stage length, oil and gas loss is big and is not easy to clean up when sealing off and causes oil vapour pollution.
The utility model patent that Authorization Notice No. is CN205534817U discloses a kind of duct closing type device, including exhaust
Pipe, sealing device and fixing device；The blast pipe, which is arranged on, to be treated in blocking pipe, and one end of the blast pipe waits to block close to this
The opening of pipeline, the blast pipe treat that one end of opening of blocking pipe is used for connection flexible pipe close to this, and the blast pipe can should
Treat that the gas leakage in blocking pipe is discharged by the flexible pipe；The sealing device is socketed in the blast pipe and treats blocking pipe away from this
Opening one end, and outer rim treats that blocking pipe contacts with this, and blocking pipe is treated for sealing this；The fixing device is socketed in this
Blast pipe close to this treat blocking pipe opening one end, treated for the duct closing type device to be fixed on into this in blocking pipe.
But the patent structure is complicated, keeps described device position to consolidate using pressing plate fixed seal ring and by fixing device
It is fixed to carry out the closure of pipeline, pipe deforming, inwall it is uneven it is smooth in the case of, plugging effect is poor, oil, gas can still occur
The phenomenon of leakage, there is potential safety hazard.
Utility model content
It is close to solve to fix using pressing plate in the prior art that the purpose of this utility model is to provide a kind of duct closing type device
Seal blocking pipe pipe deforming, inwall it is uneven it is smooth in the case of the bad technical problem of sealing effectiveness.
To achieve the above object, what the utility model carried uses following structure for duct closing type device：Duct closing type device

As a kind of improvement of the present utility model, the installed part is the base, and the interior Stop structure is located at described
On base.This is improved to have the beneficial effect that：When gland extrudes elastic sealing structure, elastic sealing structure is because being fixed on base
Without being moved at installation step, the friction loss for reducing elastic sealing structure and inner-walls of duct is preferably close so as to ensure
Seal effect.
As further improvement of the utility model, the interior Stop structure is inner shield ring, it is described press fitting part be provided with
The recess of the interior Stop structure inserting.This is improved to have the beneficial effect that：When inner shield ring can ensure that elaxtic seal is compacted
To form better seal, recess can plug together preferably to compress elastic sealing structure deformation direction with interior Stop structure.
As another improvement of the present utility model, elastic sealing structure is sealed packing, rubber seal or is lithium
The mixture of base grease and clay.This is improved to have the beneficial effect that：Sealed elastic structure uses sealed packing or rubber seal
During circle because sealed packing or rubber seal have solid shape convenient disassembly, if but inner-walls of duct deformation, inwall it is uneven
When even smooth, sealed packing or rubber seal may be not enough to be formed with inner-walls of duct completely when being compacted and seal；Sealing
When elastic construction is using the mixture of lithium base grease and clay, because this kind of mixture has more preferable plasticity, it is under pressure
Easily expansion can better adapt to deformation, the uneven smooth inner-walls of duct to be sealed of inwall afterwards, so can riser tubing closure effect
Fruit, expand the duct closing type device scope of application provided by the utility model.
As another improvement of the present utility model, it is provided between the gland and the compressing structure and is compressed to transmit
The sleeve of power, the compressing structure are the nut coordinated with the guiding bar screw thread.This is improved to have the beneficial effect that：The peace of nut
For holding position on the right side of gland, the installation site generally causes inconvenient dismounting inside pipeline, is passed using sleeve
Passing thrust can make nut be in pipeline external with convenient construction.
