PRESSUR E-REGULATING VALVE.
SPECIFICATION formingpart of Letters Patent'No. 519,089, dated May 1, 1894.
/ Application filed March 10, 1.894. $erial No. 503,137. (No model.)
.To all whom it may concern:
Be it known that 1, JOHN NAGELDINGER, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Pressure-Regulating Valves, of which the following is a specification.
This invention has reference to certain improvements in pressure regulating valves that are intended for use with fountains containin g liquid carbonic acid or other fl uids under pressure, and by which a very reliable construction that responds to the difference in pressure of the gas is supplied while at the same time the humming noise which is causedby the rapid vibrations of the valve during the escape of the gas is neutralized, and the invention consists of a pressure-regulating valve which comprises a valve-casing, a diaphragm in said casing, a tubular spindle attached to said diaphragm, a pressureregulating spring acting on said spindle, a valve attached to the end of the spindle, a slitted diaphragm supported in the cap of the casing and connected with the stem .of said valve, and a supply-pipe provided with a nozzle in line with the axis of the spindle, said supply-pipe extending into the tubular body of the spindle. The invention consists further of a damping device, which is attached to-the' plug of the cap and formed of a slitted sheet-metal shell that extends over the shank of the vibrating valve'attached to thespindle, so that the humming noise caused by the-vibration of the valve is neutralized or damped.
In the accompanying drawings, Figure 1 represents a side-elevation of my improved pressure-regulating valve. Fig. 2 isa vertical longitudinal section of the same, drawn on a larger scale. Fig. 3 is an end-elevation of the valve-casing and outlet-valve, the cap being removed. Fig. 4 is a vertical transverse section on line t4, Fig. 2, and Fig. 5 is a detail side-elevation of the damping sleeve for the outlet-valve.
Similar letters of reference indicate corresponding parts.
Referring to the drawings, A represents the casing of my improved pressure-regulating valve, which is preferably made in three sections, a cylindrical middle-section a, a smaller end-section or cap a and a larger end-section or base a The cylindrical middle-section a is provided with a supply-pipe a which is connected with a cylindrical receiver or other reservoir containing liquid carbonic acid or other fluid under pressure. The middle-section a is further provided with an outlet-pipe 0. through which the gas is conducted to the place of use, and with a pipe of that connects the valve-casin g with'a suitable pressure-gage (not shown in the drawings).
The cylindrical middle portion a of the valve-casingA is provided with an exterior screw-thread for screwing on the interiorlythreaded end-section o The opposite'smaller end of the valve-casing A is provided with an interior screw-thread into which an exteriorly-threaded portion of the cap-section a is inserted. 'The cap-section a is provided with a cylindrical extension or housing a and the opposite end-section aiwith a larger cylind ricalhousin g of, in which lattera strong helical spring 8 is arranged, which acts on a sheet-metal diaphragm D that is soldered or otherwise attached to an interior rim or flange d of the cylindrical main-section 0f the casing A. The spring 8 is adjusted to the required degree of pressure to which the gaseous fluid is to be reduced by the valve. The diaphragm D abuts against the end-section a and-carries at its center a spindle G, to the threaded shank of which is attached a washer 0' against which one end of the helicalspring s is seated, while the opposite end of the spring is seated on by a washer s that is acted upon by an adjusting-screw G which passes through the end of the cylindrical housing a and which is provided at the outside with a suitable handle C The spindle O is made of tubular shape and recessed at one side for the supply-pipe a which is provided at its inner-end with a nozzle no that is arranged at right-angles to the supply-pipe a and located axially in line with the spindle G. V The nozzle 'n is provided with a small discharge-orifice for the escape of the gas. To the end of the spindle O is applied a valve E, which is permanently connected to the end of the spindle by means of screws 6 (shown in Fig. 3). Around the shank of the valve E is arranged a sheet-metal diaphragm E, which is preferably provided with four or more slits that extend from the outer circumference of the diaphragm toward the inner edge of the same, as shown in Fig. 4, said diaphragm serving in guiding and steadying the spindle Gin its quick vibratory movements and in retaining it at the center of the valve-casing A. By providing the diaphragm with the slits, a certain degree of resiliency is imparted to the same so that it may yield to the spindle O as the latter vibrates backward and forward. The slitted diaphragm E is provided with a circumferential flange which is attached by an interior screw-ring e to the inner circumference of the cap-section a as shown clearly in Fig. 2. The valve E is provided on the side which faces the nozzle a with a central recess, into which is inserted a hard rubber block at close to the discharge-end of the nozzle it, said block being retained in position by a screw-ring. The cap-section a is provided with a screw-plug F to the inner end of which is applied a longitudinally slitted sheet-metal sleevef, that extends over a bushing f secured on the shank of the valve E. The slitted sheet-metal sleeve f exerts a frictional contact on the bushing f and acts thereby as a damper for preventing the humming noise which is produced by the rapid vibrations of the valve E in responding to the movements of the main-diaphragm D when the gas is passed from the reservoir through the pressure-regulating valve into the discharge-pipe (1 This humming noise is an annoying fea ture of the pressure-regulating valves used with receivers containing liquid carbonic acid, and is effectually overcome by the damping sleeve described which follows the vibration of the valve and damps the sound produced by the same.
When the gas is passed through the supply-pipe 01. and the nozzle .01, it expands into the valve-casing and acts on the diaphragm D. The counter-pressure of thespring s on the diaphragm D is thereby overcome, and the spindle O compelled to recede under the pressure of the gas, so as to move the valve E against the nozzle 91 and interrupt thereby the supply of gas into the valve-casing. As soon as the pressure of the spring .9 evercomes the pressure of the gas in the valvecasing, the spindle O is moved in the opposite direction, so that the valve E is moved away from the orifice of the nozzle 'n and another quantity of gas permitted to pass into the casing. As soon as the gas pressure on the valve-casing rises beyond the tension to which the spring s is set, the discharge of gas is again interrupted by the receding of the diaphragm D and the spindle C,so that the valve E closes again the orifice of the The vibrations imparted to the nozzle 92.
tubular spindle by the pressure of the gas and the tension of the spring acting on the diaphragm D produce the effective action of the valve E, so that the gas is discharged at the required lower degree of pressure from the valve-casing and then conducted to the place of use.- The valve E is guided and steadied in its motion by the slitted diaphragm, while by the sound-damping sleeve effectually neutralizes the humming noise of the valve, so that a reliable and effective pressure-regulating valve is obtained.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, of a valve-casing provided with a supply'pipe having a discharge-' nozzle at its inner end, a spring-actuated main diaphragm in said casing, a tubular spindle recessed at one side and attached to said diaphragm, a valve attached to the end of the tubular spindle and provided with a seat in line with the discharge-nozzle, and a slitted diaphragm attached to the cap-section of the valve-casing and connected with the shank of the valve so as to guide and steady the same, substantially as set forth.
2. The combination, of a valvecasing provided with a supply-pipe and a dischargepipe, a discharge-nozzle at the inner end of the supply-pipe, a spring-actuated main-diaphragm in said casing, a tubular spindle attached to said diaphragm, a valve attached to the end of the spindle, and a longitudinally-slitted sleevesupported in the cap-section of the valve-casing and extending over the shank of the valve, so as to neutralize the humming vibratory noise of the same, substantially as set forth.
3. The combination, of a valve-casing, provided with a supply-pipe having a dischargenozzle arranged at right-angles to the supply-pipe, a spring-actuated main-diaphragm in said casing, a tubular spindle attached to said diaphragm and having a side-recess for the supply-pipe, a valve attached to the end of the tubular spindle, a slitted diaphragm attached to the cap-section and to the shank of said valve, and a longitudinally-slitted damper sleeve applied to the screw-plug of the cap-section and extending over the shank of the valve, so as to prevent the humming noise of the latter, substantially as set forth.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
J OIIN NAGELDINGER.
