Kinney - Water Cooled Burner Valve - Brochure

n o J Bu ll eti n BF 113.2 Kinney Water-Cooled Burner Valve* for Blast Furnace Stoves Fast, Safe Stove Changing from Gas to Blast -Patented , 2 , , , , , J , ............ -' Stove changing from "gas" to "blast" is now fast and safe, because of the Kinney Water-Cooled Burner Valve which has re-placed the conventional burner door on many blast furnace stoves. The va lve opens or closes in 10 seconds to complete the stove changing cycle, and incorpor-ates electromechanical methods which insure maxi mum safety of operation. A number of patented features are incor-porated in the va lve. Completely steel fabricated and self-supporting, it adapts to all installations requiring minimum space; needs no costly and restrictive pits or foundations. It is available in sizes from 30" through 72", designed for 50 psi work-ing pressure and rated for 2800"F flame impingement. The Kinney Burner Valve consists of a water-cooled disc, moving vertically with-in a valve body (water cooled) and bonnet, and other supporting members and mecha-nisms which maintain a smooth, exact seating and nonstick release of the disc. The disc is flange-mounted to a hollow ground stainless steel stem which is at-tached to a manifold at the other end. The top of the stem is also connected by a lever and link system, complete with bear-ings, to the output shaft of a Kinney " Power Drive" - or other acceptable ac-tuator. The Kinney "Power Drive" is de-signed for heavy-duty equipment and is motor protected by a built-in torque device and externally mounted l imit switches; has moto r overload relays for safety, and a hand or chainwheel and declutch lever for manual operation in case of a power failure. It is interchangeable with other actuators of similar specifications.· A tubular box frame guide - a part of the superstructure - gives positive lateral control to the valve stem outside of the bonnet. A captive counterweight, safely confined on two fixed guiderods, attached to the valve stem manifold by a wire rope, and equal to the combined weight of the disc and cooling water, keeps the actuator torque output requirements to a minimum, and offers a fail-safe condition in case of a malfunction or power fail tlre. 'Manual, air or hydraulic drive also available. • • •• • ~i""r" 4 3 VALVE SEAT COOLING The two integral seats of the valve body are also water-cooled (see Fig. 3). Water enters the cooling jackets and discharges through piping connections at the base of the valve. The jack-ets are constantly vented at the top (Fig. 2) to eliminate possible air accumulation which could cause a vapor lock. The vents also provide a visual indication of the coo ling water flow. DISC SEATING Particular attention is paid to the accurate and positive seating of the disc. Both the disc and valve body have welded stainless steel seats, polished ground for positive shut-off. An ex-cl usive position seating is accomplished through externally adjustable eccentrics, (Fig. 4) located at the center line of the va lve body. In closing, wedges on the disc make contact with the eccentrics at the extended point of disc trave l, positioning the disc on the body seat. Stove pressure is utilized for additional seating pressure. A reverse action occurs for the opening cycle. At no time is the disc wiping the body seat, assuring extended seat life. A silicone rubber seal is incorporated in the disc for an absolute tight shut-off when the valve is used with a Kinney Retractable Tube Burner which eliminates burning through the valve (see cut-away drawing of disc on Page 5). Seats are provided on both sides of the disc and body. Since only one body seat is used, a simple rotation of the body 180 0 makes avail-able the unused seating surface. SECURE STEM-DISC ATTACHMENT A stainless steel adapter plate is we lded to the stem (Fig. 1) and secured to the disc with stain-less steel hexagon bolts. FLUSHING AND CLEAN OUT The Kinney Burner Valve provides an extra large clean-out arrangement. This co llecting area helps isolate the deposited dirt and mois-ture entrainment from the blast furnace gas-away from the valve seating surfaces; a major cause of seat deterioration or improper seating. Ample flushout connections are provided for recommended periodic flushing. Each Kinney Burner Valve is completely as-sembled and thoroughly tested before leaving the factory ; is shipped as an assembled unit, ready for installation. Lifting lugs are provided on each side of the valve body for conven ient handli ng. Valve flanges are concentrica lly machined and have suffiCient holes for stand-ard bolts to maintain an airtight connection. Each valve is supplied with installation, main-tenance and spare parts manuals. As with all Kinney products, the valve is com-pletely Kinney designed and engineered, man-ufactured under the most rigid quality control system in the industry, and is b{,cked by effi-cient and reliable Kinney service. 4 With Kinney "Power Drive" M'SIZE or PIPE TAP COOLING WATER REQUIREMENTS D "" ';.' l( .s.

Yoke - Levers from the actuator connect here. Bronze guide rollers. aligned to the tubular box frame, eliminate lateral stem motion. assuring smooth stem operation and minimum wear. A disc compression spring, located below the mainfold. absorbs the actuator over-travel on the closing cycle and provides accurate setting of the externally mounted limit switches, wired in series with the actuator gear train limit switches for safe stove valve sequencing. Compression of the spring leaves a gap be-tween the yoke and the manifold enabling the actuator to attain full motor speed, adding a hammer blow action for relieving a jammed disc should this condition develop. This patented feature assures extended actuator life, with reduced downtime and maintenance costs. Cool ing water for the disc travels from a port in the manifold , through a copper pipe in side the valve stem and into the disc. Vanes in the disc circu late the water in a spiral. The water then discharges upward between the outside of the copper pipe and the inside of the stem back through another man ifo ld port. Stay bolts in the disc permit it to withstand an internal cool-ing water pressure of 150 psi. This design p rovides maximum cooling efficiencies w i th a m inimum amount of wate r and pressure. 6 Kinney Water-Cooled Burner Valve with an IN-THE-LiNE Removable Water-Cooled Seat * For face-Ie-face dimensions, add 8" to those shown for the standard model, page 4. All other dimensions are identical to the standard model. This special model has all the advantages of the stand-ard Kinney Burner Valve, is constructed and operates the same, with one difference: it has a removable water-cooled seating ring which can be easily replaced to provide a new seating surface. The seating ring is c lamped in valve body at five pOints by stationary wedges and a clamping frame. Seat clamping pressure is contro lled by two (2) set screws which extend through the valve bonnet. A silicone rubber seal is incorporated to provide a positive seal between the cooling ring and the valve body. The seat can be easily replaced without removing the entire valve from line- all done without disturbing any part of the valve or main lining.
