I BClaiinsQ (014375-251) This invention relates to improvements.- iniby- ,product coke oven. standpipe valves.
' ,In by-product coke oven distillate from-coal in the oven chambers passes into standpipes and thence into a collector main. A standpipe valve is situated between each standpipe and the collector main and is closed while the oven is being charged orcoke pushed-from the oven. Tarry constituents in the distillate tend to condense around these valves and thus to gum them and interfere with their operation. To remove such condensate a solvent, commonly ammonia liquor, is sprayed continuously on the valves and is intended to wash the condensate into the collector main. An overflow is provided so. that liquor 'sprayed'while the, valve is closed passes around the valve. A sufficienthead of liquid must be maintained in the valve to maintain the; seal. against the operating vacuuinin the collector main. I V v Y Several designs of standpipe valves are now available, but those with which I am,.familiar have not beenfree'o-f gummingi .As aresult, they do not always close properly and they sometimes stick when an attempt is made to open them. In any event (opening or closing of, a valve that is. gummed is difilcult and requires excessiveforce. Occasionallyoverflows clog and cause the-liquor to back up. intostheovencchambers when the valve. isclosed. r
I'he principal object of the present invention is to provide improved standpipe'; valves less subject t ovgumming and thus being of easier and more certain operation-than previous valves with which I; am familiar. 7 Y
A further object of the invention-is to provide improvedistandpipevalves which when open furnish an unobstructed gas passage and in lvvl'nich-v thepartsare efficient-lycleaned by the liquor spray, but in which minor tardepositsdo not interfere with their operation. .A further object of the invention is: to provide improved standpipe, valves whichwhen closed furnish a constant level liquid'sea-l against: passage; of "gases. and which: have an overflow, not ik l ev A further object of the inventioniis to provide improvedstandpipe valves which: are readily accessible for inspection and manualcleaning whennecessary and in which the parts .are readily replaceable." V V L In accomplishing these and other objeots'of thecinvention; I have provided improved details of structure, a preferredform of which is shown in the accompanying drawings, which:

The standpipe has *the=-usual return bond 13- and removable "cover UL" The standpipeand collector main are ofconventional design and hence no more-:detailed ide scripti'on is deemed necessary. I I
'A valve l5 embodying features of the :present invention is interposed between the return bend of i the standpipe: and the collector main. The valve includes a body that preferably iscompos'e'd'of separable 'sections:- 16' and I]: for the seat and" dislere'spetiv'elyr The'.'sectional-:-construction of the body'facilitates ass'en1bly and dismantling-of the valve, as Well as' replacement of parts should this: become necessary; The-seat section *of the; body is situated ab'ove the -disk section "and is joined tothe extr 'eniity of t he -r-' turnbnd ofithe standpipe; through packing J 3.

lip and overflow dam constitute the valve seat. Flanges 20 and 2! are arcuate in side elevation, being constructed about a common center indicated at X (Figure 1). The seat section of the body also has a liquid seal baffle 25 that extends from the inner end wall, over the overflow dam and to a level below the upper edge of the latter.
A valve disk 26 of the gate type is mounted in disk section I! of the body on stub shafts 21 and 28 for pivotal movement on a horizontal axis. The top of the valve disk forms a closure plate which is arcuate in side elevation for en gagement with the valve seat. The arcuate plate is eccentric to the axis of pivoting; that is, the center about which the plate is constructed is offset inwardly toward the overflow dam from the axis of pivoting and, when the valve is fully closed, coincides with the center X about which flanges 20 and 2| are constructed. This eccentricity furnishes a wedging action for assisting in closing the valve. The valve disk does not scrape across the seat as it is moved,
but is pushed or wedged into engagement with the seat at the conclusion of its closing move- Shafts 2'! and 28 preferably do not extend across the valve opening so that they leave the opening unobstructed. An operating handle 29 is fixed to one of the shafts and preferably is counter-weighted at the opposite side of the. shaft as shown at 30. When the valve is closed, the counter-weight is to the left of the vertical center .line as viewed in Figure 1, and insures that the .valve does not gravitate from closed to open position. When the valv is opened, the counter-weight swings to the opposite side of the center line, where it does not tend to close the valve. The inner end wall of section I! has a stop 3| near its lower extremity against which valve disk 26 rests when the valve is open.
. The inner end wall of seat section It preferably contains relatively large poke holes 32 and 33 and smaller poke holes 34 and 35. The poke holes normally are closed by suitable plugs, but
when open furnish access to the interior of the valve. Thus the valve may be inspected readily and any tarry deposits cleaned.
The usual spraying nozzle 36 is situated in the reverse bend of the standpipe and during operation of the oven continuously directs a spray of liquid solvent, such asammonia liquor,
against the valve parts. When the valve is open, the spray efiiciently washes the seat and disk and passes directly through the valve opening into the main, where it is circulated in the usualfashion. When the valve is closed, the closure plate of the valve disk and the walls above the seat form a receptacle for retaining liquid from the spray. Liquid seal baffle 25 projectsbelow the liquid level in the receptacle and thus the liquid furnishes a seal against passage of-gases. Excess liquid overflows 1 across the top of the overflow dam, through overflow passage 24 and thence into the collector main.
From the foregoing description it is seen that I have provided a standpipe valve of simple construction and operation and in which the parts are readily accessible for inspection, cleaning or replacement. The valve parts are efflcently cleaned by the ammonia liquor spray. The eccentric movement of the valve disk with respect to the seat makes possible tight closing of the valve despite minor tar deposits and enables the valve to be opened without. sticking.
While I have shown and described only a single embodiment of the invention, it is apparent that modifications may arise. Therefore, I do not wish to be limited to the disclosure set forth but only by the scope of the appended claims.
