REVERSING VALVE FOR REGENERATIVE k1s"(.TR1\TAC'.ES.
Application led May 21, 1920. Serial No. 383,255.
provide a new and improved reversing valve.
for regenerative and like furnaces, and more particularly an improved gas reversing valve structure including a plurality of slide valves.
A further object of the present invention is to provide a reversing valve disposed and operable within the brick-work or masonry containing the chimney and regenerative flues.
Other .objects of my'invention are, to provide a slmp le and eiicient reversing valve structure in which the usual liquid seals are dispensed with, thereby greatly reducing the` initial cost of the structure as well as the cost of operations; and a reversingr valve structure of such a character as to eliminate the abrupt bends and curved passages so frequently found in gas reversing valves.
In the accompanying drawings, which illustrate an application of my invention,
Fig. 1 is a vertical longitudinal sectional view of my gas reversingvalve shown in connection with a gas box and the chimney and regenerative iues;
Fig. 2, a vertical sectional view taken on line 2-2 of Fig. 1; and
Fig. 3, an elevational view particularly showing the Water cooled valve seat and a portion of the casing.
Referring to the drawings, 2 designates a gas conduit in communication with` a gasbox 3 through which gas is introduced to-.a horizontally extending chamber 4. The passage of gas from thel conduit to the gas-box Gas-box 3 is mounted on a cover-plate 5', and 6 and 7 respectively designate separate housings designed to receive chain sheaves 8 and 9. The chain wheels or sheaves 8 and 9 are arranged in pairs, the wheels 9 constituting one 'pair are particularly shown by Fig. 2; the other pair off wheels 8 are similar to wheels or lsheaves 9. Sheaves 9 are .mounted on va shaft 10 which latter extends through the housings v7, and sheaves 8 are mounted on a similar shaft 11, the latter having its bearings in housings 6.
As illustrated and as preferred, the valve structure includes two vertically movable slidel valves 12 and 13 adapted to be conjointly operated and moved in alternate directions, each valve moving in a plane which is disposed transversely to the axes of the horizontal ports, hereinafter described. Valves 12 and 13 are similar, and include a metallic frame 14 and suitable refractory material 15. Each valve is moved into open and closed positions by means of chains 16, respectively cooperating with the wheels 8 and 9 mounted on shafts 11 and 10. Valve 12 is mounted on a vertically extending inclined and water cooled metallic seat 17, and valve 13 upon a similar seat 18.
Each valve seat 17 and 18 is formed with corresponding horizontally disposed ports 20 and 21, respectively registering with chamber 4 and with ports 22 formed in the brickwork and leading to adivided chimney iue 23. Chimne flue 23 for a portion of its length is divi ed by a partition and bafiie wall 24. One of the objects in providing wall 24 is to prevent the hot gases, during their passage 'through the structure,Y
from attacking the valves 12 and 13 when the latter are closing the ports 22 in communication with the chimney flue.
The valve seats extend upwardly through the coverplate 5 and are secured to said plate by bolts 25; the seats are also connected with the respective housings 6 and 7. 26 designates a piping system associated with the seats, whereby a cooling Huid may be circulated in the seats.
For the purpose of admitting air to the interior of the housings to cool the valves, said housings are provided with valve controlled openings 27, the valves 28 thereof being adapted to be moved to openpositions by the upward movement of the main slide valves 12 and 13, vand to be closed by the springs 29.
Valves 12 and 13 are disposed and operated within chambers 30, 30, formed by the brickwork and the housings, and, as will' be. readily understood, control the passage of gases, etc., from the chamber 4 to the regenerator - lues 31, 31, and from the regenerative or furnace flues to the chimney fiues.
In addition to the chain wheels 8 and 9 referred to above, each shaft l0 and 11 has mounted thereon a chain Wheel or sheave 32, and one of the shafts (as shown, shaft 10) is provided with a drive Wheel 33, the latter being adapted to be turned by a drive rope or cable 34 extending from said wheel 23 to a convenient point. Wheels 32 are connected by a chain 35, thus providing a construction effective to alternately raise and lower the respective valves concomitantly.
What I claim is:
1. In a reversing valve structure, the combination with oppositely disposed gas regenerator Hues and a chimney Hue disposed Within the masonry of a furnace, vertically movable slide valves controlling the passage of gases between the-regenerator. and chimney Hue, horizontally disposed ports over which the valves slide, and a baHie Wall interposed between said valves.
2. In a reversing valve structure, the combination with oppositely disposed gas regenerator Hues and a chimney Hue having a partition wall therein all disposed within the masonry of a furnace, a vertically extending ported valve-seat located between a regenerator Hue and a chimney Hue, the ports therein being horizontally disposed a vertically movable slide valve controlling the passage of the gases through the port of said seat, and means for operating the valve.
3. In a reversing valve structure, the combination with a gas supply chamber, oppositely disposed gas regenerator Hues and a chimney Hue all disposed Within the masonry of the furnace, opposite ports establishing communication with the gas supply chamber and regenerator Hues, opposite port-s establishing communication with the regenerator Hues and chimney Hue, a reciprocable valve adapted to move over one port connecting the regenerator Hue and gas supply chamber and one port connecting the regenerator Hue and chimney Hue, said valve operating to close one or the other of said ports at Will, a similar valve for the other two ports, operating means for each valve enclosed in a housing and operable from Without the housing, and means outside the housings connecting the operating means in such a manner that the two'valves may be operated concomitantly to open and close respectively different ports.
4. In a reversing valve structure, the combination with a gas supply chamber and a chimney Hue disposed one above the other, a regenerator chamber with which both the gas supply chamber and the chimney Hue communicate through horizontally disposed ports, of a valve reciprocable in a vertically extending plane to close one or the other of said ports, and means operated by said valve for admitting cooling air theretowhen the valve is closing the port between the gas supply chamber and regenerator chamber.
In testimony whereof I aHiX my signature in presenceA of two witnesses.
