Abstract
The utility model discloses a device for aligning a guide cylinder of an upper valve of a grey lock for a lurgi gasifier. The device consists of a circular pipe, an upper circular ring, a lower circular ring and a circular plate; the circular plate is fixed at the middle section of the circular pipe; two ends of the circular pipe are fixed with the upper circular ring and the lower circular ring; and the central lines of the circular plate, the upper circular ring, the lower circular ring and the circular pipe are coincided. By using the device for aligning the guide cylinder of the upper valve of the grey lock for the lurgi gasifier, the problem that the alignment of the guide cylinder of the upper valve of the grey lock is not easy to control can be solved, the influence factor that the upper valve of the grey lock for the lurgi gasifier is damaged can be eliminated, the running cycle of the lurgi gasifier is prolonged, and the economic loss is reduced.
Description
Technical field
The utility model relates to the repair and maintenance instrument that a kind of lurgi gasifier ash is locked valve, is specifically related to the alignment device that a kind of lurgi gasifier ash is locked the valve guide cylinder.
Background technology
The ash lock is the supporting ash discharge equipment with pressure of German lurgi gasifier, is responsible for the lime-ash that produces in the lurgi gasifier gas-making process being discharged in order its Working environment very severe of living in.It is one of key part of grey lock that ash is locked valve, and when the ash lock needed ash discharge, ash is locked valve needed in off position lower assurance tightly not leak.The working temperature that ash is locked valve is about 300 ℃, trim contacts with lime-ash, and the sealing between valve head and the valve seat will be born the high pressure of 3.0MPa, it is very frequent to add switch, each circulation will be moved more than ten time, repeatedly clash into trim, it is unusually fast to cause ash to lock the damage of valve, changes frequent.
Lock in the maintenance Renewal process of valve at the lurgi gasifier ash, need blowing out, pressure release, cooling after, the ash lock pulled down and be shifted, finish changing ash and lock the driving that resets again behind the valve, the lurgi gasifier at least 18 hours of must stopping transport like this causes the cycle of operation of lurgi gasifier short especially.
And lock in the Renewal process of valve at ash, because the bad control of centering that ash is locked the valve guide cylinder, ash is locked to produce easily between the valve head of valve and the upper valve base and is pounded inclined to one side phenomenon, it is inhomogeneous to cause contact surface to be puted forth effort, and can increase the weight of the damage that ash is locked valve again.
Summary of the invention
The purpose of this utility model provides a kind of lurgi gasifier ash and locks valve guide cylinder alignment device, locks the problem of the bad control of valve guide cylinder centering to solve ash.
Lurgi gasifier ash of the present utility model is locked valve guide cylinder alignment device and is comprised of pipe, upper annulus, lower annulus and disk, described disk is fixed on the stage casing of pipe, be fixed with respectively annulus and lower annulus at the two ends of pipe, and the central lines of described disk, upper annulus, lower annulus, pipe.
Wherein, the internal diameter of described upper annulus and lower annulus is between round tube inside diameter and upper valve stem diameter, specifically less than the internal diameter of pipe, greater than the diameter of upper valve valve rod.
And then the utility model also is provided with a seam that cooperates with ash lock at described disk, and the medullary ray of described seam equally and the central lines of pipe.
Also be provided with breather hole on described disk, described breather hole evenly distributes along the circumferential direction of disk.
Lock in the valve maintenance Renewal process at the lurgi gasifier ash, ash is locked valve seat and is returned before the dress, first lurgi gasifier ash of the present utility model being locked valve guide cylinder alignment device is placed on ash and locks, ash is locked the valve valve rod to be passed from its centre hole, the flange that just can lock by adjusting ash the upper and lower guide ring of valve guide cylinder is adjusted the gap between guide cylinder and the upper valve valve rod, guaranteed the grey centering of locking the valve guide cylinder, having eliminated one affects the lurgi gasifier ash and locks the valve deadline factor, prolong the cycle of operation of lurgi gasifier, reduced financial loss.
Description of drawings
Fig. 1 is the structural representation that the utility model lurgi gasifier ash is locked valve guide cylinder alignment device.
Fig. 2 locks the use state graph of using the utility model alignment device at the lurgi gasifier ash.
Embodiment
The below illustrates embodiment of the present utility model with reference to the accompanying drawings.
The lurgi gasifier ash is locked structure such as Fig. 1 of valve guide cylinder alignment device, by pipe 3, be separately fixed at upper annulus 1, the lower annulus 2 at pipe 3 two ends, and the disk 4 that is fixed on pipe 3 stage casings forms, disk 4 be provided with one with ash lock 5 seams that cooperate 6, and the circumferential direction along disk 4 is evenly distributed with breather hole 7, the central lines of above-mentioned disk 4, upper annulus 1, lower annulus 2, pipe 3, seam 6, the internal diameter of upper annulus 1 and lower annulus 2 is slightly less than the internal diameter of pipe 3, but greater than the diameter 0.5mm of upper valve valve rod 8.
Lock in the valve maintenance Renewal process at the lurgi gasifier ash, as shown in Figure 2, lock before valve seat returns dress at ash, first the lurgi gasifier ash being locked valve guide cylinder alignment tool is placed on above the ash lock 5 by seam 6 cards, then the upper valve valve rod 8 of ash lock 5 centre hole from alignment tool is passed, just can lock by adjusting ash lower flange on the guide ring of valve guide cylinder 9 and adjust gap between guide cylinder 9 and the upper valve valve rod 8, make its width between centers be no more than 1mm.
Claims (4)
1. the lurgi gasifier ash is locked valve guide cylinder alignment device, formed by pipe, upper annulus, lower annulus and disk, it is characterized in that described disk is fixed on the stage casing of pipe, be fixed with respectively annulus and lower annulus at the two ends of pipe, the central lines of described disk, upper annulus, lower annulus, pipe.
2. lurgi gasifier ash according to claim 1 is locked valve guide cylinder alignment device, it is characterized in that the internal diameter of described upper annulus and lower annulus is less than the internal diameter of pipe, greater than the diameter of upper valve valve rod.
