Definitions

  • a coke oven door is provided with a plurality of cylinder-piston assemblies having rods that coact with the sealing ring.
  • a header, capable of carrying fluid under pressure is mounted to the door and conduits connect the header to each assembly.
  • a condiut carrying such fluid under pressure is mounted to the battery with conduits connecting each header.
  • Valve means is provided in each conduit to control the flow of fluid from the conduit on the battery.
  • FIG. 1 is a vertical front elevational view of the lower portion of a coke oven door incorporating an embodiment of my invention.
  • FIG. 2 is a view along line H-II of FIG. 1.
  • a conventional coke oven door 11 is provided with a bulb angle door frame 13 to which are secured a conventional door plug 15, and a flexible sealing ring 17.
  • the sealing ring is secured, as by studs 19, to the door frame 13 and contacts a conventional seating surface 21 of a door jamb 23.
  • each assembly 25 is a piston 27 with an outwardly extending piston rod 29 that engages the sealing ring 17, as shown in FIG. 2.
  • the piston 27 is provided with a heat resistant cup seal 31 on one side and an annular heat resistant dust seal 33 on the piston rod side and surrounding the piston rod 29.
  • the free end of the cylinder portion of the assembly 25 is threaded to receive a screw plug 35 that engages a conventional O-ring 37, as shown in FIG. 2.
  • the cylinderpiston assembly 25 is provided with a tubular conduit 39 which connects to a tubular header 41 that encircles the perimeter of the door 11, as shown in FIG. 1.
  • the disconnect fitting 43 is a conventional fitting made by Snap-Tite, Inc. of Union City, Pennsylvania, and marketed under the trademark Snap-Tite.
  • Snap-Tite Inc. of Union City, Pennsylvania, and marketed under the trademark Snap-Tite.
  • a length of flexible hose 45 which carries a mating portion of the Snap-Tite coupling is secured at one end to a main fluid conduit 47 that extends along the length of the coke oven battery at a location below the bottom of all doors on the battery. Fluid under pressure, such as air, is carried in such conduit 47.
  • a suitable support 49 and removable clamp 51 is provided at strategic locations on the door frame 13 for supporting the tubular header 41, as shown in FIG. 1.
  • the benchman manually disconnects the flexible hose from the fitting and immediately the air pressure in the header drops to ambient pressure.
  • the Snap-Tite fitting is so made that when it is disconnected, a valve in the portion connected to the flexible hose closes and prevents fluid, such as air, from escaping.
  • the valve opens automatically, thereby admitting fluid to flow through the connection into the header. Fluid pressure in the door header creates equal pressure on the pistons and on the sealing knife edge.
  • That flexure of the sealing ring is greatly reduced each time the door is removed and replaced when compared to the flexure experienced with doors fitted with conventional spring plungers;
  • the fluid connection that is suggested as being manually accomplished herein, may be made automatically.
  • said means includes a fluid conducting header (c) aconduit carrying said fluid under pressure mounted capable of carrying fluid under pressure mounted to to said battery; said door with fluid conduits connected to each of 5 (d) fluid conducting means for connecting said conduit said assemblies. on said battery and said header on said door; and 1 3.
  • the invention of Claim 2 including: (e) valve means for controlling the flow of such fluid (a) a conduit carrying said fluid under pressure mounted from said conduit on said battery.
