Description
Technical field
The present invention relates to a kind of heavy wall compensator devices, expand more particularly to a kind of heavy wall for overregulating defencive function
Section.
Background technique
Heavy wall bellows expansion joint is designed using GB/T16749-1997 standard, and pressure pipeline is effectively guaranteed and is conveying
High safety performance when various harmful poisonous inflammable and explosive media avoids leakage pollution from causing the environment such as ocean, sky, factory dirty
Dye.Heavy wall expansion bellow is additional stress caused by compensating because of temperature difference and mechanical oscillation, and is arranged in container casing or pipe
A kind of flexible structure on road.Due to it as it is a kind of can free extension elastic compensation element, have rigidity is big, intensity is high,
Reliable operation, it is functional, compact-sized the features such as, be suitable for boilers and pressure vessel, high-intensitive, the shell and pipe of small compensation rate
Road has been widely used in industries such as petroleum, chemical industry, metallurgy, nuclear energy.Its products characteristics is high temperature resistant, high pressure resistant, corrosion-resistant, resistance to
It is tired, wear-resistant.Due to being small compensation rate, rigidity is very high, therefore, is set on the outside of the heavy wall bellows expansion joint between each ripple
Pressure ring is set to have little significance, and excessively compensation needs a kind of new scheme to extend heavy wall expansion bellow in operating condition in order to prevent
Machine life.
Summary of the invention
The purpose of the present invention is to provide a kind of structures simple, radial and axial to have small compensation rate, internal stress free to have
Adjust the heavy wall expansion joint of defencive function.
The technical solution for realizing the aim of the invention is as follows: a kind of internal stress free tool overregulates protection heavy wall expansion joint, packet
Include the heavy wall bellows that internal stress is eliminated through Overheating Treatment, which is characterized in that heavy wall bellows one end is internally connected with length
Cylinder, the long cylinder right end are equipped with inflexed turn along border and enclose I, and the heavy wall bellows other end is internally connected with short circle
Circle II is turned along what border was equipped with bent outward in cylinder, the short cylinder left end, it is described turn circle I and turn circle II be nested and the shape that is slidably matched
At toroidal cavity, limit annulus is equipped on the outside of the short cylinder turned on the right side of circle I.
Preferably, the width of the toroidal cavity in the horizontal direction is equal to the clear distance turned between circle I and limit annulus.
Preferably, the clear distance for turning circle I and limiting between annulus is heavy wall bellows maximum axial compensation rate.
Preferably, even circumferential is provided with fixed ball cover, the fixed ball cover on short cylinder outer wall in the toroidal cavity
Interior to be equipped with stainless steel ball, the stainless steel ball contacts respectively with toroidal cavity internal ring wall and external annulus.
Preferably, the stainless steel ball diameter is greater than 2~5mm of toroidal cavity ring width.
Compared with prior art, the present invention its remarkable advantage:, can be with due to turning circle I, turning circle II and limiting the cooperation of annulus
Realize that heavy wall compensator realizes prevention over-voltage in the axial direction, crosses and draw compensation, since stainless steel ball diameter is greater than toroidal cavity ring width,
The effect that agitates of stainless steel ball may be implemented have a certain range of compensation radially, and overrun then because of toroidal cavity
The effect of structure and realize radial prevention overcompensation function, the present invention has simple structure and convenient processing, three-dimensional overcompensation prevention
The advantage that effect is good, heavy wall bellows is long without internal stress, production life cycle service life.
Present invention is further described in detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Fig. 2 is the enlarged diagram in the portion J in Fig. 1.
Specific embodiment
As shown in Fig. 1~2, a kind of internal stress free tool overregulates protection heavy wall expansion joint, including in eliminating through Overheating Treatment
The heavy wall bellows 1 of stress, heavy wall bellows one end are internally connected with long cylinder 3, and 3 right end of long cylinder is set along border
There is inflexed turn to enclose I, 1 other end of heavy wall bellows is internally connected with short cylinder 2, and the short cylinder left end is set along border
Have bent outward turn circle II, it is described turn circle I and turn circle II be nested and be slidably matched to form toroidal cavity, it is described turn circle I on the right side of
Short cylinder on the outside of be equipped with limit annulus 4, even circumferential is provided with fixed ball cover 5 on short cylinder outer wall in the toroidal cavity,
It is equipped with stainless steel ball 6 in the fixed ball cover 5, the stainless steel ball 6 contacts respectively with toroidal cavity internal ring wall and external annulus, institute
6 diameter of stainless steel ball is stated greater than toroidal cavity ring width 3mm, the width of the toroidal cavity in the horizontal direction be equal to turn circle I with
The clear distance between annulus is limited, and the clear distance for turning circle I and limiting between annulus is heavy wall bellows maximum axial compensation rate.
In embodiments of the present invention, fixed ball cover 5 can be any dress that can fix ball position in industrial production
It sets, 6 diameter of stainless steel ball is greater than toroidal cavity ring width 3mm, that is to say, that stainless steel ball 6 supports toroidal cavity ring width big
3mm, so that occurring bigger gap between long cylinder 3 and short cylinder 2, the effect that agitates of stainless steel ball 6 may be implemented in diameter
There is a certain range of compensation upwards, and overrun, radial prevention overcompensation is realized because of the effect of toroidal cavity structure
Function；Due to turning circle I, turning circle II and limiting the cooperation of annulus 4, heavy wall compensator may be implemented realize in the axial direction to prevent
Pressure is crossed and draws compensation；The present invention has that simple structure and convenient processing, three-dimensional overcompensation preventive effect be good, heavy wall bellows is without inside
The advantage of stress, production life cycle service life length.
