Abstract
The utility model is related to a kind of forging high pressure self-locking type flange, the flange includes that there are two cutting ferrules (1)；There are four fixed bolt holes to be used for the positioning between cutting ferrule (1) with fastening respectively for described two cutting ferrules (1)；Cutting ferrule (1) inner wall is fluted, and the set section (3) is embedded in cutting ferrule (1) inboard wall groove；Described set section (3) inner wall is fluted, and the sealing ring (4) is embedded in set section (3) inboard wall groove；The set section (3) can select different materials according to the special requirement for anticorrosion of different use environments.It is exclusive new-type sealing the utility model is related to a kind of core of forging high pressure self-locking type flange, that is, relies on sealing ring（4）Sealing lip（T shape arms）Flexible deformation formed sealing, belong to hard sealing.It combines to form a powerful rigid body using the muscles and bones of set section, cutting ferrule, sealing ring, makes the intensity of connecting portion much larger than sub-pipes base material self-strength, when compression, self-tightening sealing and pipeline can be reinforced, greatly strengthen the integral strength of connecting portion.
Description
Technical field
The utility model is related to a kind of forging high pressure self-locking type flanges.
Background technology
Currently, flange is applied to the connection between wide range of areas, such as pipeline, the connection between machine is related to stone
The multiple fields such as oil, chemical industry, electric power, water conservancy, coal mine, water supply, heating, gas supply, natural gas, ship, large-scale capital construction.But it passes
The flange of system is largely to be plastically deformed by gasket to have the function that sealing, belongs to soft seal, soft seal generally existing is not
High temperature resistant, easy to wear, the shortcomings of mechanicalness is poor, are easy aging, and service life is short, are caused to maintenance, the maintenance in equipment later stage
Great inconvenience；For this purpose, there is an urgent need for a kind of install convenient, the higher flange of stability replaces original method currently on the market
It is blue.
Invention content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of install convenients, intensity higher, and leakproofness is more
It is good, the forging high pressure self-locking type flange that the service life is longer.
What the purpose of this utility model was realized in：
A kind of forging high pressure self-locking type flange, the flange include the cutting ferrule there are two flange arrangement form；It is described two
It is respectively set on the contact surface of cutting ferrule there are four fixed bolt hole, two cards is realized by the bolt being spun in fixed bolt hole
Positioning between set and fastening；The cutting ferrule inner wall has card slot, the head shoulder of two set sections to be embedded in cutting ferrule inner wall respectively
It in card slot, and covers and coordinates for lozenges between the shoulder lateral surface saved and the cell wall side of card slot, the set section is provided centrally with
Taper hole, sealing ring both sides the conical surface be embedded in taper hole respectively, realize that the sealing that sealing ring is saved with set is matched by taper hole and the conical surface
It closes.
Compared with prior art, the utility model has the beneficial effects that：
The core of the utility model is exclusive new-type sealing, that is, relies on the sealing lip of sealing ring（T shape arms）Elasticity become
Shape forms sealing, belong to hard sealing.It combines to form a powerful rigid body using the muscles and bones of set section, cutting ferrule, sealing ring, make
The intensity of connecting portion is much larger than sub-pipes base material self-strength, when compression, self-tightening sealing and can reinforce pipeline, greatly
The integral strength for strengthening connecting portion.Since set section can require to select different materials according to varying environment, greatly increase
Pull resistance, crushing resistance, impact resistance, corrosion resistance and bending resistance of the flange in specifically used.Since it is simple
Composed structure, installation process are only completed by four bolts, and cutting ferrule can determine bolt direction around set section 360 degree rotation and install
The adjustment of bolt hole in journey greatly facilitates installation personnel operation.
Description of the drawings
Fig. 1 is a kind of front view of forging high pressure self-locking type flange of the utility model.
Fig. 2 is a kind of side sectional view of forging high pressure self-locking type flange of the utility model.
Fig. 3 is the assembly effect diagram of the set section and sealing ring of a kind of forging high pressure self-locking type flange of the utility model.
Wherein：
Cutting ferrule 1, fixed bolt hole 2, set section 3, sealing ring 4, card slot 5；
Taper hole 3.1；
The conical surface 4.1.
Specific implementation mode
Referring to Fig. 1 ~ 3, the utility model is related to a kind of forging high pressure self-locking type flange, the flange includes that there are two methods
The cutting ferrule 1 of blue structure type；Fixed bolt hole 2 there are four being respectively set on the contact surface of described two cutting ferrules 1, by being spun on
Bolt in fixed bolt hole 2 realizes positioning and fastening between two cutting ferrules 1；1 inner wall of the cutting ferrule has card slot 5, two sets
The head shoulder of section 3 is embedded in respectively in the card slot 5 of 1 inner wall of cutting ferrule, and covers the cell wall side of the shoulder lateral surface and card slot 5 of section 3
Coordinate for lozenges between face, the set section 3 is provided centrally with taper hole 3.1, the conical surface 4.1 of 4 both sides of sealing ring is embedded at respectively
In taper hole 3.1, realize that sealing ring 4 and the sealing of set section 3 coordinate by taper hole 3.1 and the conical surface 4.1；Sealing ring 4 it is centrally disposed
There is through-hole；
Further, the set section 3 can select different materials according to the special requirement for anticorrosion of varying environment, to improve it
Corrosion resistance.
In addition：It should be noted that above-mentioned specific implementation mode is only a prioritization scheme of this patent, the skill of this field
Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent..
