Abstract
The utility model relates to a sectional type ultra-slender metal bellows. The sectional type ultra-slender metal bellows comprises three identical corrugated sections and two sections of identical connecting rings, wherein the three identical corrugated sections comprise a first corrugated section, a second corrugated section and a third corrugates section, the two sections of identical connecting rings comprise a first connecting ring and a second connecting ring, the first corrugated section is connected with the second corrugated section through the first connecting ring, and the second corrugated section is connected with the third corrugated section through the second connecting ring. The sectional type ultra-slender metal bellows has effects of resisting a high temperature (400DEG C) and a high pressure (12MPa), being good in seal, not prone to abrasion and the like in the working process of a pulse valve for a Shell powdered coal gasification system, and satisfies the requirement that the circulating motion service life is no less than 200 thousand times.
Description
Technical field
The utility model belongs to metal compensating element technical field, relates to a kind of segmented super-elongated metallic bellows for Shell coal gasification system sentinel valve.
Background technique
Sentinel valve be in the Shell coal gasification system in order to produce the important device of pulsing airflow, when sentinel valve is worked, must under the double-acting cylinder effect, stretch frequently and compressed action as the metal bellows of its vitals.Coal chemical industry enterprises used metal bellows in related domain structurally adopts the monolithic pressed moulding at present, existence to the tolerance poor performance of high temperature and high pressure and working life low defective, when the sentinel valve running hours, bellows is under stretching and the frequent effect of compressed action, and its inwall easily is worn, and the trough place easily produces fatigue crack, the end weld also easily produces the stretching crackle, occur leakage failure in the sentinel valve thereby make, cause the coal gasification entire system to be stopped, cause serious economy loss.
The model utility content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of rational in infrastructure, high temperature resistant, high pressure resistant, good sealing effect and nonabradable segmented super-elongated metallic bellows are provided.
The technical solution that adopts is so for achieving the above object: the segmented super-elongated metallic bellows that provides has three sections identical ripples joints that are made of first ripple joint, second ripple joint, the 3rd ripple joint and the identical connecting ring of two-section that is made of first connecting ring, second connecting ring, first ripple joint is connected with second ripple joint by first connecting ring, and second ripple joint is connected with the 3rd ripple joint by second connecting ring.
In the above-mentioned segmented super-elongated metallic bellows, weld mutually by circumferential weld between said each ripple joint and each connecting ring.
In the above-mentioned segmented super-elongated metallic bellows, the external diameter of said each butt joint ring is less than the crest diameter of each ripple joint, and the internal diameter of each butt joint ring is less than the trough diameter of each ripple joint.
In the above-mentioned segmented super-elongated metallic bellows, the external end head of first ripple joint and the 3rd ripple joint is the enlarging of surface smoothing, in order to dock other component.
In the above-mentioned segmented super-elongated metallic bellows, said first ripple joint, second ripple joint and the 3rd ripple joint are made by material, thickness, the identical internal layer corrosion resistant plate of rigidity, middle level corrosion resistant plate and outer corrosion resistant plate mold pressing, are filled with the cooled metallic bond of hot melt attitude between each layer corrosion resistant plate.
Technical solution of the present utility model comprises that also the bellows length overall after three sections ripple joints connect is 350～360mm, and diameter is 45～50mm, and the amount of tension of bellows and decrement are respectively 23mm and 10.5mm.
Compared with prior art, the beneficial effects of the utility model are: this segmented super-elongated metallic bellows can play high temperature resistant (400 ℃), high pressure resistant (12MPa), good seal, equivalence fruit not easy to wear in sentinel valve continuous operation process, and realizes that the do action life-span is no less than 200,000 times requirement.
