Abstract
The utility model provides a blind flange, including circular's chassis, seted up a plurality of connecting hole on the chassis, its characterized in that: the chassis on be provided with the anticorrosive coating, this anticorrosive coating for the disk structure be used for with flange opening looks adaptation by the assembly pipeline, the anticorrosive coating be the polytetrafluoroethylene material, the circumference outside of anticorrosive coating be close to and be provided with the annular groove in chassis department, the anticorrosive coating be close to that to be provided with the annular of extending to the outside on the circumference lateral wall on the outside in the annular groove protruding, the annular protruding be guide structure in the ascending cross -section in blind flange's installation side and set up, the annular protruding for the mobile setting of the lateral wall of anticorrosive coating in order to realize the extrusion to groove structure, this blind flange can realize sealing difficult wearing and tearing with the anticorrosive of pipeline.
Description
Technical field
This utility model belongs to a kind of blank flange.
Background technology
Blank flange is also referred to as blank flange, and rectification of name is called blind flange, is middle flange the most with holes, is a kind of flange
Type of attachment, for sealing pipe stopper.In industries such as oil, chemical industry, metallurgy, electric power, boats and ships and machineries, blank flange rises
Isolation, the effect of cut-out pipeline, be the same with end socket, pipe cap, welding plug role.It is a kind of that blank flange seals
Dismountable sealing device, and the sealing of end socket does not prepare to open again.Due to blank flange good seal performance, for needs
Completely isolated system, the most all as reliable isolating means.
Blank flange includes the chassis of round shape, and chassis offers several connecting holes, for connecting the end of pipeline,
It is connected to the end of pipeline during connection by connecting hole, and between blank flange and the end face of pipeline, is provided with sealing ring, in order to
Meeting antiseptic property, the inner side of blank flange is provided with anticorrosive coat, this anticorrosive coat is the wafer architecture adaptive with pipeline end face.
But such blank flange, constantly opening, in disassembly process, anticorrosive coat easily produces abrasion, and anticorrosive coat and pipeline
The gap that inwall exists, easily corrodes blank flange.
Utility model content
In order to overcome the defect of prior art, this utility model provides a kind of blank flange, and this blank flange can be real
Now with the preserving and sealing of pipeline, the most easy to wear.
Problem for the assembly that removably connects, it is provided that following technical scheme: a kind of blank flange, including the end of round shape
Dish, chassis offers several connecting holes, it is characterised in that: being provided with anticorrosive coat on described chassis, this anticorrosive coat is circle
Chip architecture is for suitable with the flange port being assembled pipeline, and described anticorrosive coat is polytetrafluoroethylmaterial material, described anticorrosion
The periphery of layer is provided with annular groove at chassis, and described anticorrosive coat is close to circumference on the outside of annular groove
Be provided with the annular protrusion extended laterally on sidewall, described annular protrusion cross section on the installation direction of blank flange in
Guide frame is arranged, and groove structure is squeezed with realization by described annular protrusion relative to the movable setting of the sidewall of anticorrosive coat
Pressure.
This utility model is further arranged to, and the end face of described anticorrosive coat is provided with adaptive with annular protrusion recessed
Groove.
The beneficial effects of the utility model: when coordinating installation with the end flange of pipeline, this blank flange can be with pipe
Sealing ring between road flange is socketed in the annular groove of anticorrosive coat, it is possible between avoiding existing between anticorrosive coat and inner-walls of duct
Gap thus corrode the position that blank flange is corresponding, two flanges are fixing when connecting, and anticorrosive coat is positioned at insides of pipes and is close to pipe
Road inwall, annular protrusion is deformed during installing, it is possible to groove structure produces the pressure of pretension, it is ensured that coordinate
The seal isolation at place, can ensure that after dismounting by the movable annular protrusion deformed simultaneously, be not likely to produce abrasion.
Accompanying drawing explanation
Fig. 1 is the structural representation of blank flange in this utility model embodiment.
Label signal in figure: 1-chassis；11-connecting hole；2-anticorrosive coat；21-annular groove；22-annular protrusion；23-is recessed
Groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
With reference to Fig. 1, a kind of blank flange, including the chassis 1 of round shape, chassis 1 offers several connecting holes 11, described
Chassis 1 on be provided with anticorrosive coat 2, this anticorrosive coat 2 for wafer architecture for suitable with the flange port being assembled pipeline, anticorrosion
Layer 2 is polytetrafluoroethylmaterial material, and the periphery of described anticorrosive coat 2 is provided with annular groove 21, anticorrosion at chassis 1
Layer 2 is provided with the annular protrusion 22 extended laterally, the end of anticorrosive coat 2 on circumferential side wall on the outside of annular groove 21
It is provided with on face and the groove 23 of annular protrusion 22 adaptation, it is simple to the movable deformation of annular protrusion 22, described annular protrusion 22 exists
Cross section on the installation direction of blank flange is that guide frame is arranged, and annular protrusion 22 is movable relative to the sidewall of anticorrosive coat 2
Arrange to realize the extruding to groove structure.When coordinating installation with the end flange of pipeline, this blank flange and pipe flange
Between arrange sealing can be connected in the annular groove 21 of anticorrosive coat 2 by snare, it is possible to avoid between anticorrosive coat 2 and inner-walls of duct
There is gap thus corrode the position that blank flange is corresponding, blank flange is fixed with pipe flange when being connected, and has guide frame
Annular protrusion 22 can conveniently enter in pipeline opening, anticorrosive coat 2 is positioned at insides of pipes and is close to inner-walls of duct, convex annular
Play 22 generation activity deformation during installing, it is possible in the axial direction groove structure is produced the pressure of pretension, it is ensured that
Seal isolation at cooperation.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and modification, above-mentioned vacation
If these improve and modification also should be regarded as protection domain of the present utility model.
