Abstract
The utility model is related to a kind of flange sealing structure that can arbitrarily dismantle, including locking flange, Sealing shield ring, mounting flange, the centre of described mounting flange is provided with flange hole, the upper end of the flange hole is provided with screw thread, locking flange is fixed by tightening way with the screw-threaded coupling set by flange hole, the lower end of the flange hole is through hole, by the through hole by mounting flange and pipe fitting close-fitting, Sealing shield ring is installed between the top and bottom of the flange hole, the Sealing shield ring is placed on pipe fitting, and positioned at Sealing shield ring flange hole section and flange hole lower end between pass through chamfered transition；The utility model can be dismantled at any time, dismounted more convenient, good seal performance, be relatively specific for situation about should not be welded between flange and pipe fitting.
Description
Technical field
The utility model belongs to flange sealing structure technical field, more particularly to a kind of flange seal knot that can arbitrarily dismantle
Structure.
Background technology
Should not be welded between some flanges and pipe fitting, it is therefore desirable to tighten or be fitted close, but between cooperation exist it is close
Sealing property is bad, is easily caused leakage liquid or air.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of flange that can arbitrarily dismantle
Sealing structure.
The purpose of this utility model is completed by following technical solution, including locking flange, Sealing shield ring, installation
Flange, the centre of described mounting flange is provided with flange hole, and the upper end of the flange hole is provided with screw thread, and locking flange is by twisting
Tight mode is fixed with the screw-threaded coupling set by flange hole, and the lower end of the flange hole is through hole, by the through hole by mounting flange and
Sealing shield ring is installed between pipe fitting close-fitting, the top and bottom of the flange hole, the Sealing shield ring is placed on pipe fitting, and positioned at close
Pass through chamfered transition between the flange hole section of block circle and the lower end of flange hole.The both sides up and down of described Sealing shield ring are set to taper
Face, top and the lower end of locking flange are in close contact, and are in close contact below with the inclined-plane set by flange hole.
Preferably, the material used in described locking flange, Sealing shield ring, mounting flange uses stainless steel.
The beneficial effects of the utility model are：1st, it due to the structure using screw-threaded coupling, therefore can at any time dismantle, dismount
It is more convenient；2nd, mounting flange, locking flange and Sealing shield ring use stainless steel, and therefore, the structure heatproof is very high, together
When aging phenomenon when being not in rubber seal；3rd, the structure is relatively specific for the feelings that should not be welded between flange and pipe fitting
Condition.

Embodiment
Detailed introduction is done to the utility model below in conjunction with accompanying drawing：As shown in accompanying drawing 1 to 3, the utility model includes
Flange 2, Sealing shield ring 3, mounting flange 4 are locked, the centre of described mounting flange 4 is provided with flange hole 41, the flange hole
41 upper end is provided with screw thread 43, and locking flange 2 is locked by tightening way with the screw thread 43 set by flange hole 41, the flange
The lower end in hole 41 is through hole 44, by the through hole 44 by mounting flange 4 and the close-fitting of pipe fitting 1, the top and bottom of the flange hole 41
Between Sealing shield ring 3 is installed, the Sealing shield ring 3 is placed on pipe fitting 1, and positioned at Sealing shield ring 3 flange hole section and flange hole
Pass through the transition of inclined-plane 42 between 41 lower end.
The both sides up and down of described Sealing shield ring 3 are set to taper face 31, and top and the lower end of locking flange 2 are in close contact,
It is in close contact below with the inclined-plane 42 set by flange hole 41.
Described locking flange 2, Sealing shield ring 3, the material used in mounting flange 4 use stainless steel, therefore, should
Structure heatproof is very high, while aging phenomenon when being not in rubber seal.
Operation principle of the present utility model：Mounting flange 4 is first inserted on pipe fitting 1, pipe fitting 1 and the close-fitting of flange hole 41, set
Enter a Sealing shield ring 3, Sealing shield ring 3 has to pass through heat treatment, and hardness is bigger than pipe fitting 1, then locking flange 2 is screwed into installation
Flange 4, when locking flange 2 and touching Sealing shield ring 3, due to Sealing shield ring both sides stress about 3, the both sides of Sealing shield ring 3 are again
Taper face 31 is designed to, so when locking flange 2 is tightened, lock sealing back-up ring 3 is squeezed, and tightly encases pipe fitting 1, plays close
The effect of envelope, due to Sealing shield ring 3 devise above and below two tapers, so being dual-seal.
The utility model is not limited to above-mentioned embodiment, and any change is made no matter being constituted in its shape or material, all
It is to use structure design provided by the utility model, is all a kind of deformation of the present utility model, is considered as new in this practicality
Within type protection domain.
