Description
Technical field
The present invention relates to a kind of gases to convey special flange component.
Background technology
In gas transportation facilities, ring flange is applied to pipeline connection and is found everywhere, general ring flange, sealing
Face is all circular planes shape, is welded on two ring flanges that pipeline opening goes out, is symmetrically installed together, the sealing surface of two ring flanges
Contact be by seal washer as airtight and watertight padding, the anchor ring of this ring flange often makes gasket due to installation dislocation
Circle dislocation is lost, or is broken through by barotropic fluid since seal washer self deterioration is cracked and cause to reveal, this ring flange
Sealing contact surface it is smaller, radial alignment is short, is not enough to blocking barotropic fluid and leaks, the leakage time is slightly long, will result in close
The damage of cover, if conveyance conduit results in blockage in addition, the pressure of barotropic fluid is axial compressive force, and excessive pressure is more than locking screw
Two flange connections fractures can be caused when the connection of bolt, then cause gas leakage.
Invention content
It is an object of the invention to overcome defect existing in the prior art, a kind of gas conveying special flange group is provided
Part is not susceptible to dislocation so that seal washer is lost, and makes the pressure of barotropic fluid by axially becoming by structure change
It for radial direction, and cancels out each other, therefore the disengaging of flange assembly will not be caused line clogging, it is existing that leakage will not occur
As.
To achieve the above object, the technical solution of the present invention is to provide a kind of gases to convey special flange component, including
First flange and the matched second flange of the first flange are set between the first flange and the second flange
Gasket, several positioning columns, the top setting of the positioning column are fixedly uniformly arranged on the joint face of the first flange
Have convex hemispherical protrusion, offer several hemispherical grooves on the joint face of the second flange, the convex hemispherical protrusion with
The hemispherical groove is arranged in a one-to-one correspondence, and the positioning column is hollow structure with the convex hemispherical protrusion and mutually interconnects
It is logical, several skewed slots being connected with the positioning column are offered on the endoporus of the first flange, in the convex hemispherical protrusion
The venthole that several radial directions along the first flange open up is offered, the venthole is interior with the convex hemispherical protrusion
Chamber is connected, offered on the gasket with the matched centre bore of the endoporus of the first flange and second flange, with
Matched first perforation of several positioning columns is worn for the bolt for connecting first flange and when second flange connects
The second perforation crossed.
It is further improved to be：The gasket is flexible gas gasket.
It is further improved to be：Annular groove is offered on the outside of the positioning column, in the first perforation of the gasket
It is provided with and the matched annular bead of the annular groove.
It is further improved to be：The positioning column is welded and fixed with the first flange.
The advantages of the present invention are：Several positioning columns, therefore flange group are set on a flange wherein
When part connects, since the presence of positioning column makes flange assembly that inconsistent phenomenon will not occur in connection, gasket is prevented
It loses, ensures the service life and sealing effect of flange assembly, opened in the convex hemispherical protrusion by positioning column end in addition
If radial venthole so that when pipeline blocks, in the case of intraductal atmospheric pressure rapidly rises, the active force of high pressure gas
Direction is radially distributed and cancels out each other, to prevent the clamping screw of two flanged joints of high pressure gas pair from impact being caused to prevent
It falls off.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Wherein：1, first flange；2, second flange；3, gasket；4, positioning column；5, convex hemispherical protrusion；6, skewed slot.
Specific implementation mode
Below in conjunction with the accompanying drawings and embodiment, the specific implementation mode of the present invention is further described.Following embodiment
It is only used for clearly illustrating technical scheme of the present invention, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of gas conveys special flange component, including first flange 1 and the first flange 1 match
The second flange 2 of conjunction, the gasket 3 being set between the first flange 1 and the second flange 2, the first flange 1
It is fixedly uniformly arranged with several positioning columns 4 on joint face, the top of the positioning column 4 is provided with convex hemispherical protrusion 5, and described
Several hemispherical grooves are offered on the joint face of two flanges 2, the convex hemispherical protrusion 5 is a pair of with the hemispherical groove one
Should be arranged, the positioning column 4 and the convex hemispherical protrusion 5 are hollow structure and are interconnected, the first flange 1 it is interior
Several skewed slots 6 being connected with the positioning column 4 are offered on hole, are offered in the convex hemispherical protrusion 5 several along institute
The venthole that the radial direction of first flange 1 opens up is stated, the venthole is connected with the inner cavity of the convex hemispherical protrusion 5, described
Offer on gasket 3 with the matched centre bore of the endoporus of the first flange 1 and second flange 2, with it is several described fixed
The position perforation of column 4 matched first, for for connecting that bolt when first flange 1 and second flange 2 connect passes through
Two perforation.
In order to improve the leakproofness of flange assembly, the gasket 3 is flexible gas gasket 3, close by flexible gas
Two flange seals are prevented gas from leaking by packing 3.
It is further improved the leakproofness for improving flange assembly, the outside of the positioning column 4 offers annular groove, described close
When be provided in the first perforation of packing 3 with the matched annular bead of the annular groove, positioning column 4 and the cooperation of gasket 3,
Annular bead is located in annular groove, since gasket 3 is that elasticity utilizes flexible deformation, greatly improves sealing effect.
In order to facilitate processing, the positioning column 4 is welded and fixed with the first flange 1, processes first flange 1 first, and
Skewed slot 6 is bored afterwards, and hollow positioning column 4 is finally soldered to corresponding position, it is easy to process.
The basic principles and main features and its advantage of the present invention have been shown and described above, the technical staff of the industry answers
The understanding, the present invention is not limited to the above embodiments, the original for only illustrating the present invention described in above-described embodiment and explanation
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It all fall within the protetion scope of the claimed invention, the claimed scope of the invention is by appended claims and its equivalent circle
