The metal bellows for the pulse valve has the functions of motive seal, high temperature resistance, high pressure resistance and the like in the working process of the pulse valve for a high temperature and high pressure fly ash filtering system, and is used in cooperation with the reciprocating cylinder, and the metal bellows can stretch by 23 mm and be compressed by 10.5 mm repeatedly for 0.2 million times under the high temperature and high pressure environment.
Description
Technical field
Content of the present invention relates to a kind of sentinel valve metal bellows for gasification High Temperature High Pressure flying dust filtration system.
Background technique
Sentinel valve is the important device of the online blowback cleaning systems of ceramic high temperature high pressure fly ash filter filter core in Shell gasifying powder coal device, in order to produce pulsing airflow, and the oppositely clean solid impurity (filter cake) being attached on filter core.In the time that sentinel valve is worked, must under double-acting cylinder effect, stretch and compressed action as the metal bellows of its vitals, and act frequently, the response time is short; Simultaneously, along with the progress of technology, related domain is having higher requirement in applying working condition, project organization and working life for sentinel valve, the structure length that not only requires metal bellows is long, diameter is thinner, and require it can bear the directly etching of high temperature (being not more than 350 ℃), high pressure (being not more than 12MPa) crude synthesis gas, and there is higher service life cycle (being not less than 200,000 times), but up to now, coal chemical industry enterprises can't meet above-mentioned functional requirement with the metal bellows product of known sentinel valve.
Summary of the invention
The problem that the object of the invention is to prior art to exist is solved, a kind of sentinel valve metal bellows for gasification High Temperature High Pressure flying dust filtration system is provided, this metal bellows can bear the directly etching of high temperature, high pressure raw synthetic gas, and length is longer, diameter is less, and service life cycle is not less than 200,000 times.
For achieving the above object and the technical solution adopting is such: the sentinel valve providing has three sections of ripples joints that connect successively by connecting ring and one with metal bellows and run through the driveshaft that inserting is crossed each ripple joint endoporus and can be done to move back and forth under compound cylinder drive, one end of driveshaft is connected with double-acting cylinder and external equipment by connecting thread, the other end coordinates installation with support guide Mechanism Clearance, the bar section place that approaches connecting thread at driveshaft is set with a mounting flange, initial mouthful of end of first section of ripple joint is by head end circumferential weld and mounting flange welding, the end mouth end of end ripple joint is by the support guide mechanism connecting head section welding of tail end circumferential weld and driveshaft.
Above-mentioned sentinel valve, with in metal bellows, welds by middle part circumferential weld between said each ripple joint and connecting ring mutually.
Above-mentioned sentinel valve is with in metal bellows, bellows overall length after said three sections of ripples joint connects is 350～360mm, diameter is 45～50mm, and the amount of tension of bellows and decrement are respectively 23mm and 10.5mm, and the overall length of said driveshaft is 600～610mm.
Above-mentioned sentinel valve is with in metal bellows, and the mounting flange being sleeved on driveshaft is the mounting flange of a peripheral hardware mounting hole, and this mounting flange is connected with external equipment by mounting hole.
When system works, by the alternative air of two ventilating holes, impel double-acting cylinder to do reciprocatory motion, therefore can drive driveshaft motion, and then drive the bellows that is connected in it to carry out reciprocatory motion.In bellows course of action, it is isolated with extraneous formation intrasystem high temperature, high pressure raw synthetic gas, simultaneously bellows is along with the work of system can complete the action of stretching 23mm, compression 10.5mm in a circulation 250ms, and guarantees not occur the faults such as leakage, fracture in systemic circulation action 200,000 times.
Compared with prior art, beneficial effect of the present invention is: this sentinel valve can play motive sealing, the function such as high temperature resistant, high pressure resistant with metal bellows in High Temperature High Pressure flying dust filtration system sentinel valve working procedure, and combine use with double-acting cylinder, can under high temperature, hyperbaric environment, complete the do action of metal bellows stretching 23mm, compression 10.5mm, realize the do action life-span can reach 200,000 times.
