Description
Technical field
It the utility model is related to a kind of Hermetical connecting structure of flange.
Background technology
Flange（Flange）, it is called ring flange or flange.Flange is the part for making pipe be connected with each other with pipe, is connected
In pipe end；Flange connection is exactly two pipelines, pipe fitting or equipment, is first individually fixed on a ring flange, then at two
Flange gasket is added between ring flange, it is detachable that two ring flanges are finally tensed to the one kind for making it combine closely with bolt
Joint.
In the tank body of some HTHPs, tank mouth is connected with flange, and the flange is tightly connected by terminal pad, makes its work
Make, due to being frequently added material so that flange and the frequent dismounting of terminal pad are opened, and the flange of Hermetical connecting structure is typically tied
Structure has tongue and groove flange, face-flange and male and female flange, and face-flange is due to making flange gasket in tank body, by height
Extreme influence service life after gentle high pressure, causes often to change, influences production efficiency, and male and female flange needs when closed
Bumps could match somebody with somebody to it is closed, and has larger requirement for the technology of worker, and general bumps are not alignd, and just sealing coordinates not
, so that work difficulty is larger, and the sealing surface of tongue and groove flange is that pad is put with being combined into by a tongue and groove and a groove face
In in groove.Applicable pad has：Metal and nonmetallic plain cushion, metaled gasket, wound gasket etc..As male and female flange, tongue-and-groove
Face flange gasket will not be extruded in groove, and it is minimum to compress area（The only 52-68% of face-flange and male and female flange）, pad
Piece uniform force.Because pad and medium are not directly contacted with, dielectric corrosion influences and the permeation effects of pressure mechanism are minimum, can use
In the occasion that the seal request such as high pressure, inflammable, explosive, poisonous medium is strict, but the processing of this sealing surface and pad replacing compared with
For difficulty, be not suitable for the sealed connection often dismantled.
The content of the invention
To solve the above problems, the purpose of this utility model is to provide a kind of method of good sealing effect and convenient disassembly
Blue Hermetical connecting structure.
To achieve the above object, the utility model provides following technical scheme：A kind of Hermetical connecting structure of flange, bag
Flange and terminal pad are included, the flange is provided with the groove of annular, seal washer, the terminal pad are provided with described groove
On be convexly equipped with crushing block that is corresponding with the groove and setting in a ring, pass through screw between the flange and the terminal pad
When tensing combination, the crushing block presses the seal washer, and drives in the seal washer side face expansion and the groove
Wall keeps impaction state.
For the section of the crushing block into triangle, the triangular tip of the crushing block is embedded in the end face of the seal washer
In.
Described triangle is equilateral triangle or isosceles triangle.
The section of the crushing block is into triangle, and the tip setting of the triangle is in the arc-shaped, in the triangle
Positioning flank is respectively equipped with outside portion, the end face of described seal washer is provided with " V " type groove corresponding with the crushing block
Should, the two side angle of the V " type grooves is acute angle.
This structure of the present utility model, when tensing combination by screw between flange and terminal pad, crushing block presses institute
Seal washer is stated, and drives the seal washer side face expansion to keep impaction state with groove inner wall, can so be effectively improved close
The effect and structural openings of envelope, make the dismounting of flange and terminal pad very convenient, reached good sealing effect and dismounting side
Just technique effect.
The utility model is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the stereogram of the utility model embodiment；
Fig. 2 is the schematic perspective view of flange in the utility model embodiment；
Fig. 3 is the schematic perspective view of terminal pad in the utility model embodiment；
Fig. 4 is the Hermetical connecting structure figure of the first scheme of flange and terminal pad；
Fig. 5 is the Hermetical connecting structure figure of flange and the disk second scheme of connection.
Embodiment
As shown in Fig. 1-Fig. 3, the Hermetical connecting structure of this flange 1, including flange 1 and terminal pad 2, flange 1 are provided with
The groove 11 of annular, seal washer 3 is provided with groove 11, is convexly equipped with corresponding with groove 11 in terminal pad 2 and sets in a ring
The crushing block 21 put, when tensing combination by screw between flange 1 and terminal pad 2, crushing block 21 presses seal washer 3, and drives
The expansion of the side face of seal washer 3 is set to keep impaction state with the inwall of groove 11.
As shown in figure 4, the section of crushing block 21 is into triangle, the triangular tip embedding sealing packing ring 3 of the crushing block 21
End face in.It so can expand outwardly the inner and outer circumferential surfaces of seal washer 3, make the inner and outer circumferential surfaces of sealing ring and the inwall of groove 11
Impaction state is kept, so as to effectively improve compression sealing area, so as to improve sealing effectiveness, while flange 1 and terminal pad 2 is existed
Crushing block 21 during assembling due to triangle can be freely movable in groove 11, makes the sealed connection of flange 1 and terminal pad 2 more
It is convenient and reliable.
Triangle is equilateral triangle or isosceles triangle.For crushing block 21 in embedding sealing packing ring 3, stress is more equal
Even stabilization, improve the effect of sealed connection.
As shown in figure 5, the section of crushing block 21, into triangle, the tip setting of the triangle is in the arc-shaped, in triangle
Interior outside portion on be respectively equipped with positioning flank 22, the end face of seal washer 3 is provided with " V " type groove corresponding with crushing block 21
31, the two side angle of " V " type groove 31 is acute angle.Such scheme can make the circular arc of the end face of crushing block 21 extrude " V " type groove
The inwall of 31 both sides, two side is set to expand outwardly respectively, so as to produce thrust, the expansion of two side side wall to the inwall of groove 11
Positioned respectively by the positioning flank 22 on crushing block 21 afterwards, make the structure of sealing relatively reliable, do not only reach sealing so
Connection can also make the sealed connection of flange 1 and terminal pad 2 and dismounting more convenient.
This structure of the present utility model, when tensing combination by screw between flange 1 and terminal pad 2, crushing block 21 touches
Densification seal washer 3, and drive the expansion of the side face of seal washer 3 to keep impaction state with the inwall of groove 11, it can so effectively improve close
The effect and structural openings of envelope, make the dismounting of flange 1 and terminal pad 2 very convenient, reached good sealing effect and dismounting
Convenient technique effect.
