Description
Technical field
The present invention relates to the valve base sealing structure of a kind of continuous reforming regeneration device catalyst regulation cutting ball valve, belong to stream
Body control valve technical field.
Background technology
In the locking hopper blanking unit of modern crude oil Refining Chemical Industry continuous reforming regeneration device, use about 0.89MPa
High pressure nitrogen downstream pipelined diameter about 1.5～the catalyst granules of 1.6mm, this place install catalyst regulation cuts
Interception valve, as " throat " of catalyst transport pipeline, its performance parameter and service life directly affects the production of package unit
Efficiency and time between overhauls(TBO), the working condition residing for cutting ball valve of the catalyst regulation simultaneously is the most sufficiently complex:
1. easy buildup.After flowing through a large amount of catalyst granules entrance valve of pipeline, it is very easy in various gaps inner accumulated, long
The spring plenum length at the valve seat back side is blocked by the phase granule of accumulation, makes valve seat follow the string, and then causes valve event bite, sealing
The catastrophe failures such as surface wear aggravation are on-the-spot；
2. easy bite.In valve switch course of action, if high rigidity catalyst granules is mixed in valve ball and sealing surface of seat
Between, sealing surface can be made by sharp wear, and then cause the phenomenons such as valve leakage automatic inspection increase, action bite；
3. erosion is serious.The high rigidity catalyst granules of a large amount of diameters about 1.5～1.6mm is right under the effect of 0.89MPa pressure reduction
Ball surface carries out strong and lasting erosion, and this requires that sphere need to have higher hardness to ensure the service life of valve；
4. seal request is high.According to technological design, it is desirable in the case of the most reversely applying 0.89MPa nitrogen, valve
Seat leakage rate meets ASME B16.104 CLASS VI；
5. operating frequency is high.Technological design needs according to continuous reforming regeneration device, locking hopper blanking control valve needs every year
Action 160000 times, once, the sealing property of valve to be ensured, this is to valve seat and valve ball in average every about 3min action
The ratio pressure of sealing pair, the especially elastic compensating structure of valve seat proposes the highest requirement；
Summary operating mode, continuous reforming regeneration device locking hopper blanking unit is to the preventing materials accumulation of valve, anti-jamming, sealing
Energy and operating life all propose the harshest requirement.In current prior art, generally use common V-type ball valve conduct
Locking hopper blanking control valve, owing to there are the various gaps such as counterbalance spring space, valve seat and valve body fit-up gap, is often urged
Catalyst particles accumulation, block and cause the fault such as valve event bite, sealing surface inordinate wear, and due to close between valve seat and valve ball
Sealing, sphere hardness higher than pressing through not enough, valve rarely exceeds 2～3 months service life, too short the making of catalyst blanking control valve
Quality stability and the production efficiency of package unit is seriously limited with cycle, too high repair rate.
Summary of the invention
The invention aims to solve the problems referred to above, it is provided that a kind of simple in construction, CONTINUOUS REFORMER compact to design
The valve base sealing structure of regenerating unit catalyst regulation cutting ball valve, it is possible to for continuous reforming regeneration device locking hopper unit
Catalyst regulation cutting ball valve provide a kind of preventing materials accumulation, anti-jamming, seal valve base sealing structure reliable, long-life, it is ensured that dress
Put stable, Effec-tive Function.

Present configuration is simple, and compact to design, service life is long, can be widely applied to oil refining industry continuous reforming regeneration dress
Putting in locking hopper blanking control valve, beneficial effect includes:
(1) valve seat uses the unitary piece of metal thin plate made of inconel nickel-base alloy material to make, it is to avoid in conventional valve holder structure
The risk that cavity necessary to counterbalance spring is blocked by catalyst granules；
(2) valve seat both sides are full symmetric, and wherein can commutate after the sealing surface wear of side use opposite side sealing surface, significantly improves
Service life of valve seat；
(3) valve seat self has preferable elasticity, and direct being pressed on valve body by hold-down ring forms sealing, both can be with valve ball
Reach preferable sealing effectiveness, it also avoid the excessive sealing surface caused of seal pressure and surprisingly wear and tear；
(4) without nonmetal parts such as O in valve base sealing structure, improve the use temperature range of valve；
(5) the first sealing flange on hold-down ring and the second sealing flange are close for improve between sheet metal valve seat and valve body
Envelope is than pressure, it is ensured that sealing property；Defining flange is less than sealing flange plane 0.2～0.3mm, makes sheet metal valve seat have suitably
Deformation space, it is to avoid seal pressure is excessive；
(6) the ball surface hardness using two-layer compound spraying technology to carry out cure process is up to HRC58～62, can be the most right
The erosion of highly hard catalyst granules.
