i Application filed August 7,1903- Serial Ne.168,559i
To aZZ whom it mag concern:
Be it known that I, JULIUS A. DYBLIE, a citizen of the United States, and a resident of J oliet, county of Will, and State of Illinois, have invented certain new and useful Improvements in Valve Mechanism, of which the following is a full, clear, and exact descri tion.
T is resent invention has relation more particu arly to that class of valve mechanism used in connection with the blowing-engines of converting and blast furnace plants and the invention consists in the features of improvements hereinafter described, illustrated in the accompanyin drawings, and particularly pointed out in t e claims at the end of this specification.
Figure 1 is a view in central vertical section through a valve mechanism embodying my invention. Fig. 2 is a view in horizontal section on line 2 2 of Fig. 1.
The casing A of my improved valve mechanism is provided with an induction-port a and with a dischar eport a, the inductionport being adapte for attachment tothe pipe leading from the blowing-engine, while the port a is adapted for attachment to a pipe leading to the mains whereby the blast of air is delivered to the furnaces. Around the induction-port a is formed a valve-seat 2, that is ground to receive a disk-sh ap ed valve B, whereby the port a may be closed. Through the valve B passes the stem B, to which the valve B is connected, and one end of the stern' B passes through and is guided by a boss 3 at the center of the spider-arms 4, that arepreferably cast integral with the casing A at its induction-port a. The opening a in the casing A opposite the port a is closed by a head A, formed separate from the casing and conv-Lniently bolted to exterior flanges around the port (L This head C is provided with a cylinder 0, that is preferably formed integral with the head C, and in this cylinder 0 works a piston D, that is fixed to the stem B of the main valve B. The inner end of the cylinder 0 is open; but, as shown, its outer end is closed, and through this outer end passes the valvestem B. In order to counterbalance the weight of the valve B, I prefer to attach to the upper end of the valve-stem B a counter balance-weight. As shown, the upper end of the stem B 5, to which is pivotally connected the lower end of a link 6, the upper end of this link 6 being pivotally connected to the inner end of has attached thereto a coupling to equalize the pressure on thecounterbalance-lever E, that carries at its opposite end the counterbalance-weight E, preferably adjustable upon the lever. The counterbalance-lever E is supported by a standard F, that rises from the top of the easing-head C. The inner face of the head 0 is preferably strengthened by interior webs 0 as shown in Fig. 1 of the drawings.
The upper end of the cylinder 0 is connected with the interior of the casing A, so that substantially the same air-pressure may be delivered to the top and to the bottom of the valve-controlling piston D. Preferably the connection between the upper end of the cylinder c and the interior of the casing A is effected by a pipe or channel G, that leads from the top of the cylinder 0 through the head 0 of the casing, and, as shown, this pipe or channel G is provided with an exhaust-port g and with a three-way valve H, that will be furnished with a suitable handle, whereby it may be conveniently manipulated.
When the blowing-engine is to be started, the attendant should turn the three way valve H so asto open communication between the upper end of the cylinder 0 and the atmosphere. When this has been done, the air-pressure from the blowing-engine lifts the valve B from its seat, and the air-pressure that is witlnn the casing and main pipes connected therewith from other engines, if such there he, acts on the under side oi the piston D, that is attached to the valve-stem B, and maintains the valve B in its full-open position. if no other blowing-engines are attached to the delivery-niains of the system, the pressure of air admitted from the blowing-engine through the induetion port a will after a few strokes of the engine accumulate sufiiciently to cause the piston Dto hold the a valve B in its raised position. in open posi- L: H, h 1,, t}, d +1 rel MOD the pressure on so si e, die ta ve is balanced, but that on the piston D is not balanced, and the pressure on the under side of the piston will he sufficiently larger than that on the upper side to hold the valve in open position. When the blowing-engine delivering air through the casing A is to be shut down and it is desired to close the valve B, the attendant will turn the three -way valve H from the position shown in Fig. 1 a quarter-revolution, thereby establishing communication between the top of the cylinder c and the interior of the casi A, so as bothsiees of thestem and a cylinder for said piston, said cylto permit the shi inder having valve mechanism and orts for placing the opposite ends of the cy inder in communication with the interior of the valvecas' and with the atmosphere respectively to h dld the valve open, and for equalizing the pressure on 0 posite'sides of said piston of the valve to closed position, substantially as described.
3. Avalve of the characterdescribed comprising a casing having a valve -seat, a disk valve on the discharge side ofsaid valveseat, exposed on itsopposite sides to the inlet and discharge pressures respectively and a stem connected to said valve and provided with a piston of less area than said valve, a cylinder for said piston, said cylinder being open at one end and having a by-pass leading from the valve-casing and a port leading from the atmosphere both opening into its opposite end, and valve mechanism controlling said b the opposite sides of the piston to different fluid-pressures to hold the valve 0 en and to equal fluid-pressures to'permit t e shift of the valve to closed position, substantially as described.
4. A valve of the character described comprising a casing having a valve-seat, a disk valve arranged on the discharge side of said valve-seat, ex osed on its opposite sides to the inlet and discharge pressures respectively and arran opened when the inlet-pressure exceeds the discharge-pressure, a stem connected to said I valve and provided with a piston of less area than said valve, a cylinder for said iston, a by-pass or channel leading from the ischarge side of the valve-casing and a port leadin from the atmosphere or opening into one en of said cylinder and valve mechanism controlling said by-pass and port for exposing the opposite sides of said piston to different pressures to hold the valve open and to equal pass and port arranged to expose ed to be automatically;
