Abstract
The utility model belongs to the helium inspection technical field of sealing technology of high-pressure oil pipe, and in particular to a kind of helium inspection sealing device of high-pressure oil pipe.The helium of the high-pressure oil pipe examines sealing device, including sealing frock, spanner, mandril and seal plug, seal plug is equipped in the sealing frock, seal plug is connect by connecting rod with external spanner, and the side that the sealing frock is located at seal plug is equipped with locating piece.The beneficial effect is that: efficient advantage high, fraction defective is low, sealing effect is good, and False Rate is lower than 1%；Plug durability is high, improves service life, and greatly reduces the loss in efficiency as caused by replacement vulnerable part；It is high-efficient.
Description
Technical field
The utility model belongs to the helium inspection technical field of sealing technology of high-pressure oil pipe, and in particular to a kind of helium inspection of high-pressure oil pipe is close
Seal apparatus.
Background technique
Existing sealing means are the sealing of both ends sealing ring, and oil pipe bulb rear portion is blocked using U-shaped card slot, and forward end seal circle is logical
It crosses screw thread to screw, so that sealing ring is close to bulb, achieve the effect that sealing；It possibly can not since bulb is spherical structure, when positioning
It is aligned with oil pipe axle center, causes bulb leading portion there may be offset, the contact of bulb and sealing ring is uneven, causes
It can not be sealed up under 200Bar pressure；Since sealing means screw for screw thread, sealing ring can be born in rotary course with bulb
Tangential force causes the sealing ring service life poor, and when thread seal is by high pressure, and there are the risks of loosening, increases the bad of helium inspection
Rate.
Utility model content
In order to make up for the defects of the prior art, the utility model provides a kind of helium of high-pressure oil pipe to examine sealing device.
The utility model is achieved by the following technical solution:
A kind of helium inspection sealing device of high-pressure oil pipe, including sealing frock, spanner, mandril and seal plug, the sealing
Seal plug is equipped in tooling, seal plug is connect by connecting rod with external spanner, and the sealing frock is located at seal plug
Side be equipped with locating piece.
Further, the seal plug end is equipped with seal area.
Further, the cross section profile of the seal area is trapezoidal.
The beneficial effects of the utility model are: efficient advantage high, fraction defective is low, sealing effect is good, and False Rate is low
In 1%；Plug durability is high, improves service life, and greatly reduces the loss in efficiency as caused by replacement vulnerable part；It is high-efficient.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Attached drawing 1 is the structural schematic diagram of the utility model.
In figure, 1 mandril, 2 locating pieces, 3 seal plugs, 4 sealing frocks, 5 spanners, 6 seal areas.
Specific embodiment
Attached drawing 1 is a kind of specific embodiment of the utility model.A kind of helium inspection sealing dress of high-pressure oil pipe of the utility model
It sets, including sealing frock 4, spanner 5, mandril 1 and seal plug 3, is equipped with seal plug 3, seal plug in the sealing frock 4
3 are connect by connecting rod with external spanner 5, and the side that the sealing frock 4 is located at seal plug 3 is equipped with locating piece 2.
Further, 3 end of seal plug is equipped with seal area 6.
Further, the cross section profile of the seal area 6 is trapezoidal.
The helium of high-pressure oil pipe of the utility model a kind of examines sealing device, and when sealing, oil pipe is caught in locating piece 2 first,
Bulb is located among mechanism；Then it is fastened by pressurization spanner 5,6 domain of bulb seal area will be withstood in the pressure of seal plug 3, it is fixed
After firmly, part and sealing mechanism are put into togerther cabinet automatic-sealed end, principle is same as above；Manual sealing mechanism is placed on supporting block
On, in test, the cylinder of automatic end can pressurize, and plug, which can advance, withstands bulb, achieve the effect that sealing, be completed
Afterwards, part is taken out from cabinet, unlocks manual sealing end, part completion of processing.
The utility model is not limited to above embodiment, anyone, which should learn, makes under the enlightenment of the utility model
There is same or similar technical solution with the utility model, each fall within this
Within the protection scope of utility model.
Technology that the utility model is not described in detail, shape, construction portion are well-known technique.
