Description
Technical field
It falls off emergency processing method and device the present invention relates to catalyst slide valve flashboard, more particularly to production line is not stopped work
On-line processing method.
Background technology
Catalytic unit is oil, chemical industry tap wound effect unit.There are many sensitive regulation and control guiding valve, these cunnings for catalytic unit
Valve, because catalyst long term high temperature is worn, is likely to that valve rod fracture occurs, valve plate can not be opened freely in production process
The problem of pass, gently then drop amount underrun, etc. chances again shut-down (breakdown) mainteance solve；Heavy then necessary horse back emergency shutdown repairing, makes
At up to ten million lost revenues, influence huge.
All the time, valve link has generation with valve plate break-off in each oil, chemical enterprise, accounts for about accident total amount
10% to 15%.With the extension of petroleum chemical enterprise's time between overhauls(TBO), this problem can will increasingly protrude, and currently in addition to device
Stopping except overhauling, there is no other good solutions.The drawbacks of shut-down (breakdown) mainteance, is not only that lost revenue is big, also：1. examining
It is long to repair the time, delays manufacturing schedule, and equipment cooling is slow when shut-down, when going into operation equipment heating also slowly to rise；2. once stopping work, again
It goes into operation, it may appear that many unexpected equipment and production problem；3. can may not once go into operation success when going into operation；4. shutting down is held
Easily there are many safety problems.

Connect cylinder body 101 and with communicated inside cylinder 101.
The leading screw mandril diameter is advisable with 20-30mm, and 25mm is best.
Embodiment 2
A method of using the catalyst slide valve flashboard described in embodiment 1 fall off emergency treatment device disposition damage guiding valve,
The valve body 5 of the guiding valve includes three layers of ecto-entad：The shell 501 of metal material 16Mn, wall thickness 20mm；The heat preservation of thickness 80mm
Lining 502；The silicon of thickness 20mm hands over net 503,650 DEG C of medium temperature to include the following steps：
S1：In 5 back side precise location mounting flange pipe nipple 3 of guiding valve and press and open holes are carried out, boring cutter effective length is more than
140mm, length calculation method 20+80+20+6（Knife base thickness）+14（The inefficient length of point of a knife or apex point）, material is high temperature
Alloy knife, hardness hand over net 503 higher than silicon；
S2：Valve plate emergency treatment device is installed on flange spool 3, valve plate top therein return device 1 includes leading screw mandril 102；
S3：Leading screw mandril 102 can pierce into institute's trepanning, and guiding valve flashboard 4 can further be pushed to open guiding valve 5, be located at 5 other side of guiding valve
The valve rod of fracture can still push guiding valve flashboard 4 to close guiding valve 5, restore 5 regulating and controlling effect of guiding valve, each switch guiding valve flashboard 4 is equal
It opens purging bypass 2 to be purged, main function is to ensure that gate valve 104 does not influence to close because catalyst returns, and purging is situated between
Matter can be the low-pressure steam or nitrogen for not influencing production.
Osseotomy site requires location of the core in the center of 4 side of guiding valve flashboard, and position error is less than 2mm.
In the present embodiment, on-line branching is using superhigh temperature, exceptional hardness, the disposable trepanning of more materials, conventional press and open holes
