PRESSURE-REGULATOR.
SPECIFICATION forming part of Letters Patent No. 310,347, dated January 6, 1885.
Application led June 21, 1884. (No model.)
T0 LZZ whom, it may concern:
Be it known that I, GEORGE Wns'riNG HOUSE, Jr., a citizen ofthe United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Pressure -Itegulators of which improve ments the following is a specification.
In the accompanying drawings, which make part of this specification, Figure l is a vertical central section through a pressure-regula` tor embodying my invention; Fig. 2, a sectional elevation looking upward,and taken at the line .r c of Fig. l; and Figs. 3 and 4 views in elevation and on a reduced scale illustrating applications of the weight to the valve stem.
The object of my invention is to enable the pressure of fluid in a pipe, reservoir, or other containing-vessel having more than one source of supply to be regulated to a desired degree by primarilyvarying or closing the admission of fluid to the containing-vessel, and subsequently opening an outlet or discharge therefrom.
The improvements claimed are hereinafter fully set forth.
. In application for Letters Patent filed by me of even date herewith I have illustrated the application of my improved pressure-regulator in an arrangement of apparatus for i'urnishing power and heatin a building, the regulator acting therein to limit tothe desired degree the pressure of steam supplied directly from the generator to the steanrheaters, and also to relieve any overprcssure in the supply-pipe of the heaters that may result from a supply oi` exhaust-steam thereto above therequirements of the apparatus.
y improvements are readily adaptableunder the above orany other conditions in which regulation of pressure is supplied and relief of excess of pressure are necessary or desirable, and effect in use the simplification and economy incident to the performance of both of said functions by a single apparatus.
In the practice of my invention I provide a coupling` or connection, l, suited to be introduced at any desired point into a line of fluid* conducting pipe, and having female threads 2 cut in its opposite ends to admit ofthe same bcing properly secured to the adjacent sections of the line of pipe. A tubular valve, 3, which is closed at its upper and open at its lower end, which acts as a relief-port, is fitted truly, so as to move freely but without leakage of fluid in a valve-casing, 4, formed on the coupling l,t-i'aiis\feisely thereto, and closed at top by a suitable cap, 5, and at bottom by a screwplug, V(l. or other cover adapted to make a tightjoint. An annular chamber, 7, formed in the lower portion of the casing 4, communicates with a lateral discharge nozzle, 8, adapted to receive one end of a suitable discharge or waste pipe. A partition or diaphragm, 9, bored out truly to admit of the passage of the valve 3, extends across the coupling 1, and a series of supply-openings, l0, is formed in the valve 3, adjacent to its upper end, so as to be fully in communication with the space on the upper or supply side of the partition 9 when the valve stands in its lowest position. Delivery-openings 11 in the shell Vof the valve establish communication between the inside thereof and the space on the lower or delivery side of the partition. A stem, 12, secured to the upper end of the valve 3, and passing through the cap 5 of the valve-casing, is loaded by a weight, 13, bearing upon its top, either directly, asin Fig. 3, or through the intermediation of a lever in the manner of a safety-valve, as in Fig. et, the imposed weight, added to that of the valve and stem, being such as to institute a downward press ure cq'ual to that which is desired to be maintained in the pipe or vessel to which fluid is to be supplied by the valve.
In operation fluid from the generator or source of higher-pressure supply, entering the valve through the supply-openings 10,will act against the closed upper end of the valve as a ,piston or abutment, and raise the valve until, by the closing of the openings 10 against the bore of the upper portion of the casing, the area of said openings is so far reduced as to allow of the admission of only a sufiicient quantity of fluid to countcrbalanee the downward pressure of the weight, and consequently to maintain the desired pressure corresponding therewith in the vessel connected to the delivery end of the coupling l, and the area of the openings 10 will be increased or diminished by movements of the valve effected by variations of supplypressure coincidently with and in inverse ratio to such variations. Upon accretion of pressure in the receiving pipe or vessel, which may occur from a delivery in excess from another source of supply or from other causes, the increased pressure will induce a farther upward movement of the valve, such movement closing the supply-openings l0, and being continued until its open lower end is brought into communication with the annular chamber 7 oit' the cas- Y ing, the supply-openings l0 being meanwhile closed, upon which lluid will escape through the lower end of the valve into said compartment and into the discharge-nozzle 8 and the discharge pipe connected thereto, reducing the pressure in the receiving-pipe, and permitting the weight to depress the valve to its normal position for the admission of fluid at the required delivery-pressure, the downward movement of the valve first closing the open end to the chamber 7, and thereafter uncovering to the necessary degree the supply-openings 10.
I claim herein as my invention- I. In an apparatus for regulating and relieving excess of fluid-pressure, a valve having supply-ports, delivery-ports, and a reliefport located, respectively, at different points in its length, said ports being adapted by the movement of the valve to effect the supply of fluid when the valve is in certain positions and the relief of pressure when in other positions, substantially as set forth.
2. The combination of a valve-casing having supply and delivery connections and a discharge-passage, and a Weighted tubular valve fitting in said casing and having supply-ports, delivery-ports, and a relief -port located, respectively, at different points in its length, said. supply and delivery ports controlling communication between the supply and delivery connections, and said delivery and relief ports controlling communication between the delivery connection and the dischargepassage, substantially as set forth.
3. The combination of a valve-casing having supply and delivery connections separated by a partition, and a discharge-passage on one side of said partition, .a weighted tubular Y valve passing freely through said partition, and having a closed and an open end, ports formed in said valve adjacent toits closed end and controlling communication between the supplyconnection and the interior of the valve, and ports intermediate between the ports first specified and the open end ofthe valve, and establishing communication between the delivery-connection and the interior of the valve, substantially as set forth.
In testimony whereof I have hereunto set my hand.
