Description
Technical field
The utility model is related to mechanical part field more particularly to a kind of sealing flanges.
Background technology
Flange is called flange flange disk or flange.Flange is the part being connected with each other between pipe and pipe, is used for pipe end
Between connection；Flanged joint is exactly that two pipelines, pipe fitting or equipment are first individually fixed on a ring flange, two methods
Between blue disk, in addition flange gasket, is tightened together with bolt, connection is completed.Some pipe fittings and equipment have carried ring flange,
And belong to flanged joint.Flanged joint is the important connection type of pipeline construction.Flanged joint is easy to use, can bear compared with
Big pressure.In industrial pipeline, the use of flanged joint is very extensive.Within the family, pipe diameter is small, and is low pressure,
Invisible flanged joint.If in a boiler room or production scene, the pipeline and equipment of flanged joint everywhere.According to
Connection type flanged joint type can be divided into：Slip-on-welding plate flange, hubbed clip-on-welding flange, band neck W.N flange, socket welding flange,
Screwed flange, blind flange, band neck welding neck collar loose flange, weldingon collar loose flange, ring groove flange and blind flange, major diameter are flat
Plate flange, major diameter hubbed flange, spectactle blind, welding neck collar loose flange etc..
However, in many cases, as on vacuum tube furnace, often needed sealing flange structure, sealing flange relatively common
Flange has higher requirement to leakproofness, and the sealing flange of the prior art especially exists there are still bad drawback is sealed
Under conditions of high temperature and pressure, the sealing requirements higher of flange.
In conclusion it is that the prior art lacks a kind of good seal performance and can be suitble to high temperature, hyperbaric environment flange.
Utility model content
In order to solve the above technical problems, the utility model provides the better flange of sealing performance.
A kind of sealing flange is suitable for tube body, including mounting flange, supported flange and sealing ring；The mounting flange is
It is the integral structure that one end has recess portion that one end, which has the integral structure of protrusion, the supported flange,；The mounting flange
It is connect with the port of the tube body, the protrusion of the mounting flange is placed on the outside of the tube wall at the port of the tube body；Institute
Supported flange is stated on the outside of the tube wall at the port of the tube body；The compression method is inserted into the protrusion of the mounting flange
The blue recess portion is additionally provided with the sealing ring in the recess portion of the supported flange；The mounting flange, the compression method
The blue and described tube body sealing is fixed.
Preferably, described sealing ring at least two.
Preferably, further include baffle ring, the baffle ring is set between every 2 sealing rings.
Preferably, the baffle ring axis can move axially in the recess portion of the supported flange along the tube body；To protect
Two sealing rings of barrier are pressurized balanced.
Preferably, the mounting flange side wall is equipped with port, and the port is connected to the tube body；Further preferred institute
It is the ports KF to state port, can be with vacuum pressure in testing tube by this port.
Preferably, the supported flange further includes the cooling device for filling cooling material, and the cooling device includes closed
Empty slot, the cooling device be set to the supported flange the recess portion outside.
Preferably, the cooling material includes cooling water and cooling gas；Under hot environment, cooling material can be sealing
Circle cooling, prevents sealing ring from failing under high temperature environment.
Preferably, the mounting flange is water cooling mounting flange, the supported flange is water cooling supported flange, the sealing
Circle is " o " type sealing ring.
Compared with prior art, the technical solution of the utility model has the following advantages：The flange of the utility model uses
Plug in construction, sealing effect is good, easy for assemble or unload between mounting flange and supported flange；The utility model also adds end
Mouthful, port is connected to the tube body, pressure and temperature in tube body can be monitored at any time, when temperature and pressure reaches the flange limit
Ancillary measure can be taken in time；The utility model is also additionally arranged the cooling device for filling cooling material, under hot environment, cooling thing
Matter can be that sealing ring cools down；The baffle ring axis of the utility model can be moved axially along the tube body, different so as to ensure
Sealing ring uniform force.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of the sealing flange of the utility model embodiment.
Specific implementation mode
The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
As shown in Figure 1, a kind of sealing flange, including mounting flange 1, supported flange 2, baffle ring 4 and sealing ring 3；Fixation
Orchid 1 includes protrusion 1.1 and port 1.2, and supported flange 2 includes recess portion 2.1 and cooling device 2.2.Mounting flange 1 and tube body 5
Port connects, and the protrusion 1.1 of mounting flange 1 is placed at the port of tube body 5 on the outside of tube wall；Supported flange 2 is set to the port of tube body 5
