GAS-BEGULATING VALVE.
Specification of Letters Patent.
' Patented Oct. 28, 1919.
Application filed April 9, 1919. Serial No. 288,776.
To all whom it may concern:
Be it known that I, HENRY C. MAUL, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented cerof a gas regulating valve in accordance with tain new and useful Improvements in Gas- Regulatin Valves, of which the following is a speci cation, reference being had therein to the accompanying drawings.
My invention aims to provide a gas regulatmg valve which has a wide range of action by bein adjustable to meet requirements with eit er high or low pressure artificial or natural gas, and particularly low pressure natural gas. It is in this connection that my invention aims to provide simple means whereby the velocity of gas and its volume may be separately re lated to give a proper combustion under a l pressure conditions and in accomplishing this result I preclude any danger of back flash and eliminate noise incident to the discharge of gas from the nipple of the valve particularly when the gas is under high pressure.
To burn gas for heating purposes, it must be mixed with oxygen before it leaves the orifices or ports of a burner, and this is ac complished by having a jet of gas pass through a tube of larger diameter than the jet at a point where it leaves the orifice and since di erent qualities of gas require different proportions of ox gen, the greater the velocity of the jet 0 gas through the tube, .the ater the amount of oxygen that will be injected and commin 1e with the gas. Then again, since the ve ocity of the gas depends upon the pressure thereof, it is obvious that when the velocity is increased it will inject too much air or oxygen and will make the mixture too lean or thin to burn. In view of these facts, I have devised a valve embod ing a velocity or regulating chamber an a volume or jet regu latingchamber said chambers being so arranged as to be easilyadjusted, whereby the volume, pressure, velocity and air injecting powers may be minutely re lated.
My invention will be better un erstood when reference is had to'the drawing and the detail construction thereof, showing one embodiment of m invention which has been thoroughly teste under artificial and natural gas conditions, and found very; satisfactory, yet I do not care to confine my invention to the precise construction and arrangement of arts other than defined by the ap ended c aims.
In t e drawings,
Figure 1 is a longitudinal sectional View my invention; showing the valve on a larger scale than actually used;
Fig. 2 is a cross sectional view taken on the line IIII of Fig. 1; and
Fig. 3 is a similar view taken on the line III-III of Fig. 1.
In the drawing,- the reference numeral 1, denotes a valve body having a tapering bore 2 for a valve plug or stem 3, which is ported as at 4, and provided with an operating handle 5 and a tension device 6, said tension device maintaining the plug or stem 3 normally seated in the valve body 1 to insure a non-leakable connection between said plug and body. The valve body 1 is also provided with transversely alining or opposed inlet and outlet connections or nipples'7 and 8 adapted to communicate through the medium of the orted plug 3. The elements thus far described with the exception of the outlet connection or nipple 8, are of a conventional form along the lines of a pet cock and form no part of my invention other than valvular means for controlling the supply of gas or other fuel to the outlet connection or nipple 8.
My invention resides in providing the outlet connection or nipple 8 with a conical closure 9 which .has lts converging walls provided with a series of outlet openings 10 adapted to discharge gas at an angle to the axis of the nipple 8, and that portion of the conical wall between the openin s 10 and the extremity of the closure 9 a ords an annular valve seat 11, the purpose of which will hereinafter appear.
The outlet connection 8 may be conveniently referred to hereinafter as an inner nipple, since it is exteriorly screwthreaded as at 12, to receive the nut portion 13 of an outer nipple 14 having a tube 15 terminating in the tent or jet member 16.
The outer nipple 14 provides a pressure or velocity regulating chamber 17 adjacent the conical closure end of the inner nipple into which gas is discharged by the openings 10. At the juncture of the chamber 17 and the tube 15, there is an annular shoulder or valve portion 18 that confronts the conical valve seat 11 and coii erates therewith in providing a restricte passage between the pressure chamber 17 and the tube 15, and with the outer nipple adjustable on the inner nipple, it is possible to re ate the passage of gas from the chamber 1 into the tube 15 by lncreasing or decreasing the area of the passa e between the valve seat 11 and the valvu ar portion 18. With the walls of the pressure chamber 17 confronting the conical closure or end of the inner ni Ie, the chamber 17 tends to retard or ba liib the as admitted by the openings 10, and a furt er restriction or baflie is incurred by the shoulder or valve portion 18, which being adjustable relative to the inner ni ple can regu ate the pressure or velocity 0 gas entering the tube 15.
The et member 16 has a central or axial jet opening 19 and at the base of the 'et member or its juncture with the end of t e tube 15 there are a plurality of an larly disposed o enings or orifices 20 pro erably greater in iameter than the central jet openin 19.
he tube 15 is exteriorly screw threaded to accommodate a ca 21 having a nut portion 22 and a centre outlet opening 23 in its outer end, said outlet otpenmg being of a sufiicient size to receive e extremit of the jet member 16, and with said ca ad ustable on the tube 15, the inner on of the outlet opening 23 may be moved to and from the conical surface of the jet member. The conformation of the cap 21 afl'ords a volume or jet regulating chamber 24 and a valve portion 25, the former receiving gas throu h the openings 20 from the tube 15, and t e latter cooperating with the jet member 16 in providing a restricted passage between the chamber 2-1 and the outlet opening 23. The walls of the chamber 24 tend to retard the emission of gas from the-tube 15 and 'by adjusting the cap 21, the volume and size of the jet of from the opening 23 may be easily regu ated. The central jet opening 19 will provide a constant supply of gas for a jet of predetermined volume and size but to this jet may be added additional gas from the chamber 24 and the auxili jet openings 20 so that the volume of t e jet may be increased to insure proper air injecting in connection with a burner.
By adjustin the outer nipple relative to the inner nipp e the ressure or veloci of the gas is regulated in the tube 15 an by adjusting the cap 21 on said tube the volume or size 0 the jet is regulated, and on account of the constructive arrangement of parts the regulation is made at separable points, which 'is a desideratum in the manufacture of such valves, 'insomuch that the being known in one part 0 diflerent from another part ressure of gas the country as of the country,
it is possible for the manufacturer to adjust the outer nipple relative to the inner nipple so that the valve will properly function under a predetermined pressure. Then, it is optional with the user of the valve to adjust the cap 21 and obtain a jet volume of desired size. However, it is preferable that both adjustments be made by the manufacturer so that a plumber or other artisan, inexperienced in gas pressures, may install the va ve without regulating the same.
I am aware that a few valves have been constructedwith this end in view, and after thorou hly testing such valves they have been ound defective particularly with a low pressure of gas; some of the valves being eflective where the gas pressure is from" four to eight ounces, but in no instance did I find a valve that would properl function with a pressure from one to eight ounces, whereas my valve has such a wide range of operation and consequently can be safely and economically used with either artificial or natural gas.
I attach considerable importance to the spaced arrangement of the pressure and volume chambers 17 and 24,. respectively, particularly the fact that these chambers are about a common axis with a wall of each chamber constitutin a valve restrictingthe outlet of each cham er. This constructive arrangement of parts permits of each part being accurately formed and properly assembled, and there is no danger of an excessive pressure accidentally shifting any of the parts.
What I claim is 1. In a gas regulating valve, adjustable structures adapted to have gas passtherethrough and providing longitudinal] spaced cham ers about a common axis wit onepf said chambers for regulatin the volume therethrough, and an adjusta 1e cap on the other chamber for regu of said regulated volume. I
as regulating valve comprising inner nipple, a chambered outernipple on said inner nipple, and a; chambered cap on said outer nipple, said nipples being in longitudinal spaced relation with each providmg cooperating valve parts, with one valve part in advance of the other. 3. A gas regulating valve comprisin an inner nipple having a conical apertured closure afl'ordin a valve seat between the apertures and t e extremity of the nipple closure, an outernipple on said inner ni ple havin a valve portion movable to and fiom the vfive seat of said inner nipple so that said inner nipple may be comp etely closed and an adjustable cap on said outer nipple. 4. The combination of a as valve having an inner nipple, an adjustable outer nipple and an adjpstable cap, said nipples and sai cap having a common axis and all provided ating the pressure with outlet openin said inner nipple havmally communicating chambers one in ading an apertured c osure extending into said Vance of the other. 10 outer nipple and affording a seat to and In testimony whereof I aflix my signature from which said outer nipple is movable, in the presence of two witnesses.
