Abstract
A kind of flanging type is tightly connected metal compensator, it is made up of bellows and the adpting flange positioned at bellows both ends, the both sides of the bellows are respectively equipped with adpting flange construction section, dig composition flange in the end of adpting flange construction section, adpting flange is set with adpting flange construction section, and flange is close to the end face outside of adpting flange.The utility model bellows is directly connected to using double flare form with adpting flange, eliminate the welding bead between middle adapter and carbon steel and stainless steel, the drawbacks of avoiding unlike material weld seam from easily ftractureing, the service life of compensator is effectively improved, reduce the generation of the accident of compensator leakage failure.The utility model is simple in construction, and production method is simply controllable, is advantageous to preferably ensure sealing property and compensator ability.
Description
Technical field
It the utility model is related to the sealed connection metal compensator of a kind of conduit component, particularly flange
Background technology
Metal compensator is the device for absorbing the pipeline caused by the reason such as expand with heat and contract with cold or equipment size change,
Its composition includes a bellows, two pipe nipples and the adpting flange of sealed connection.The structure of existing metal compensator product is such as
Shown in Fig. 3：Bellows both ends soldering adapter, each adapter respectively with adpting flange soldering.Because bellows material is stainless steel
Matter, adapter and flange use carbon steel material, and two kinds different material welding difficulties is larger and weld seam is also easy to produce weld crack.Simultaneously
Weld thermal stress caused by local heating, residual stress caused by the different material of two kinds of thermal coefficient of expansions is set not disappear
Remove, cause compensator commissure in displacement process is absorbed damaged at first, make compensator leakage failure.This problem is to compensator
Life-span produce considerable influence.
Utility model content
The purpose of this utility model is the drawback for prior art, there is provided a kind of by saving adapter and unlike material
Welding bead, the flanging type for improving service life are tightly connected metal compensator.
Problem described in the utility model is realized with following technical proposals：
A kind of flanging type is tightly connected metal compensator, is made up of bellows and the adpting flange positioned at bellows both ends,
The both sides of the bellows are respectively equipped with adpting flange construction section, and composition flange is dug in the end of adpting flange construction section, connection
Flange sleeve is mounted in adpting flange construction section, and flange is close to the end face outside of adpting flange.
Above-mentioned flanging type is tightly connected metal compensator, and the lateral surface of each adpting flange is provided with seal groove, the flange pressure
Close in seal groove.
Above-mentioned flanging type is tightly connected metal compensator, and the flange is bilayer.
The utility model is improved for solving the problems, such as at metal compensator unlike material that crackle easily occurs for welding bead,
Devise a kind of flanging type and be tightly connected metal compensator.Bellows in the compensator uses double flare form and flange
It is directly connected to, eliminates the welding bead between middle adapter and carbon steel and stainless steel, the disadvantage for avoiding unlike material weld seam from easily ftractureing
End, the service life of compensator is effectively improved, reduce the generation of the accident of compensator leakage failure.The letter of the utility model structure
Single, production method is simply controllable, is advantageous to preferably ensure sealing property and compensator ability.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged view at A in Fig. 1；
Fig. 3 is the structural representation of existing metal compensator.
Each list of reference numerals is in figure：1st, adpting flange, 1-1, seal groove, 2, adpting flange construction section, 3, bellows, 4, turn over
Side.
Embodiment
Referring to Fig. 1, adpting flange 1 of the utility model by bellows 3 and positioned at bellows both ends is formed.With common metal
Compensator is different, and the utility model is not provided with end pipe, but is directly connected by bellows with adpting flange.
Referring to Fig. 1, Fig. 2, the both sides of bellows 1 extend outward respectively, form the connection method for assembly connection flange
Blue construction section 2, each adpting flange are set at adpting flange construction section, and the end of adpting flange construction section is dug composition and turned over
Side 4.Seal groove 1-1 is provided with the lateral surface of each adpting flange, the flange 4 being structure as a whole with bellows is pressed together on seal groove
It is interior.To improve the intensity of flange, flange uses double-decker.
When the utility model makes, adpting flange is inserted in after corrugated pipe forming, then be located on the outside of adpting flange in bellows
Position rise one unicast of type, and by the unicast, its seal groove with adpting flange compresses, and forms the flange of bilayer.Using this reality
Adapter is eliminated with new structure, avoids the welding bead between carbon steel adpting flange and corrugated stainless steel tubing, production method is simple
It is controllable, it can preferably ensure sealing property and compensator ability, extend the service life of product.
Claims (1)
1. a kind of flanging type is tightly connected metal compensator, it is characterised in that：By bellows（3）With the company positioned at bellows both ends
