VALVE.
Application led November12'5,1921. Serial No. 517332.
To all whom 1f/may concern,
Be it known that I, JUsTUs citizen-of the United States, residing 'at- Chicago, in the county of Cook Aand State ofl Illinois, have invented new and use-ful Improvements in Valves; and I doihereby declare' that .the followingis a yfull,- clear, and exact description ofthe invention, whichwill enable' others skilledy 'inthe art to' which it appertains to make andnuse-.tlie same.
valves.. It pertainsmore particularly, how-v ever, to a VValve ofthe pressure-relation reg-1 ulating type.
One -of the objects of the* `invention the;
provision of an i adjustable seat for the closure offa valve, especially of' thetype named, whereby thenecessary reearea for thelflow of agas ymay be .obtained 4without disturbing the lnormalv position-of certain diaphragme oarryingsuch closure.v
Another object is the provision ottant ad-` justable seat for the closure of afvalve em-'r ploying diaphragms carrying sai'dclosure whereby 'an exact `disposal of said:- seat with respect tothe closure is possible. Y
Still another object is to combine an.I acljustable .seat ,withl the clos-ure of a valve of the -type formingzthe subject of my copending..patentapplication. No. 364,840? iiled MarchlO, 1920l wherein, by the usefot such adjustable. seat, deposits or accumulationsof sediment, scale `v`from* 4the' pipe system, small chips -and particles of 'dirt which may ob-. struct the :free area of e the valvel passages will be' readily `discharged without disturbing the normal position of the diaphragms..
In the appended drawing.forming` part of this application,
Figure 1 1s a longitudinal section eleva-` tion of a pressurerelatlon regulating valve showing the adjustable valve-seat of my in- Vention applied thereto;
Figure `2'is a similar view of details of vpart `of-what is shown in Figure l, produced on a larger scale and Figure 3 is an. -elevation of an adjustable valve-seat seat shown in Figure l."-
Theirst two figures illustrate-the typefof valve ot my orme'rapplication referred to and since described in that'application its details will vnot' be explained` herein except in so'far as mayberequired to show their relationshipin connection'` with the lpresent invention.

integralpart of thevbody of .the Ivalve itlis Thisinvention relates to-.improvements in' lVhen. aval yefseat .isffixed foraformsian quite diliicult, even. with careful machining, to obtain the .proper orexactrelation be.f tween it; andthe closure when. the body parts. are bolted r together',l since eithery thcf seat4 will4 have lsuch a position relativelytofthesaid closure that it -will engage :said cl'osu-re and therethrough stress the diaphragme y.from their normal 4positions iin..one direction,.- which 'would cause them. to loe-more for-.less unresponsive4 to .the .pressure of.v gas, yora-the seat .may beso far faway-tromthei closure as Jto-vmake the control of .therefrigerant diiiicult, requiringthe-adjustmentoi the .said closure towardtheseat by loutside.. means. in the kother rdirectionwhichV in.I turn vwould, in some casesy again..'deliectfthe diaphragme from their `:normal or propenworking-posiftions and make. them'more orfless-unr-espon-y sive, and su'liicient' flexibility ,would bek-lackn ing to. permit. free .action and allow accumu-y lation vof foreign l.matter -,to be discharged... In view of the diilcultiesvusuallyncouns tercd, .it is my ;purposed .to .furnishanY tad-1 j ustable seat -by f which. the proper working co-nditions maybe vmade possible; .l f In the drawing 1 designates .the bodygfot the valve provided with. va recess 2,.whichin the assembled valve isa closed cavity,l aswill be understood f later, icommunicatingJ with which isa passage 3for.theintroduction-ot a highA pressure gas. l
Communicating with .the bottom-mot;y the recess is .a .threaded bore' 4 yconnecting .said recess' with a cavity 5 insaid body.l Inthe lower portion.y of the body lcentrally' iny line with the bo-re 4 is afcavity 1 5 j Having threaded engagement: with: `the bore 4 is -a tubular member. 7 whose upper end terminates in a conically.fonmeduvalvef seat 8. Said member has a. transverse bore 9 communicating withkawpassage 10 `inthe bodyas the outlet-for low pressure-gast The vertical passage l1 of thefmember .7 communicates with:` the cavity 5 y for .1 a p urpose` to bedescribed.- a f j A stem 12 is part of the member 7 and extends into and through the cavity 6 of the body, and threaded into the latter is a packing nut 13 which confines and compresses a packing 14: around said stem. y l
Preferably a capr or bonnet 13 encloses the protruding squared end of the stem and has threaded engagement with the nut 13.
Mounted upon the body 1 and secured thereto by means of a screw 15, for example, isa bonnet 16k and an intermediate section 17, the latter having interposed between it and the recess 2 of said body a diaphragm 18. Between the bonnet and said intermediate section 17 is a second diaphragm 19, larger than the other, while 20 is the closure carried by the two diaphragms adapted to work in conjunction with the seat 8 to control the refrigerant entering through the passage 3 and leaving through the passage 10.V The arrangement of the closure and diaphragms is substantially the same as my former application referred to, and, being well known for that reason, requires no further elucidation.
As in the device of said application the high and low pressure gases are designed to reach the small and large diaphragms, respectively, for the operation of the closure.
If the diaphragms, which are fixed with respect to the closure 2O, are flexed in one direction by mechanical means acting on the closure in order to carry said closure to the proper working position with respect to the'valve-seat 8, or the seat if too high engages ythe closure and flexes s aid diaphragms in the other direction, these members cannot properly function.
The provision .of the adjustable seat per- /mits any desired relation thereof with respect to the closure without-the diaphragms being affected in any way. Therefore, said diaphragms retain at all times the true working form and consequently are readily influenced by pressure of the refrigerant, yielding exact results. f
The seat adjustment provides for the necessary free area for the flow of the refrigerant without disturbing the normal position of the diaphragms. Said seat may be moved farther away from and closer tov the closure by turning it by means of the stem 12, as normally required, and can be fixed in proper position by any good means if found necessary. Any change in the normal and adjusted condition of the refrigerating system which reacts upon the valve will be properly readjusted by the closure as it'moves with the influenced diaphragms, until normal and original conditions are re-established. For example, if an accumulation of sediment, scale from the pipe system, small chips and particles of dirt obstruct the free area of the passage Vbeneath the closure, the low pressure will yto obtain an exact relation between the seat and closure is of no little importance for the reasons stated, as is well -known to those familiar with and having to do with valves of this type as used with refrigerating systems particularly. f
The range of adjustment of the member 7 upon its threads is never suoli as to materially change the effective area of the low pressure passages 9, 10. The accumulations when blown through are trapped in the cavity 5 after having passed down through the bore 11, Vthis being likewise true of any oil that may pass through the valve. However, this provision for catching the accumulations and oil may not be resorted to, the adjustability of the seat being the point of importa-nce to be kept in mind.
Preferably a gasket 21 is let into the body 1 at the bottom of the recess 2. This closely hugs the threads of the member 7, which it encloses, so that the pressure of the gas and small accumulations of oil will closely seal the threads against leakage of gas pressure therealong.
I claim: v l
1. The combination with a valve including a passage extending through the body ofl the valve, a closure, and diaphragms carry-1l ing said closure, of a valve-seat in said passage for receiving the closure adjustable in the said body in the direction of said closure.
2. The combination with a valve including a passage extendingthrough the body thereof and a. closure for said passage, of a tubular valve-seat seated in said passage opposite the closure and adjustable therein in the direction of said closure a discharge passage communicating with the bore of said seat between its ends, and a collection chamber connecting with said bore atpthe opposite endV thereof from the closure.
3. The combination with a valve including a passage extending through the body thereof, and a closure for said-passage, of a tubular member including a valve-seat disposed in said passage opposite the closure and adcasing and extending into said high pressure chamber, and means operable from outside the casing for adjusting said valve seat.
5. A valve of the character described, cornprsing a casing provided With a high pressure chamber and a 10W pressure chamber, diaphragms of different areas forming a portion of said chambers respectively, e valve carried and controlled by said dia- 10 phragrns, a collection chamber, a tubular valve seat adjustably threaded into said oasing in position to cooperate ywith said Valve, said seat opening at one end into thehigh pressure chamber and at its other end into said collection chamber, land a discharge 15 duet communicating With said Valve seat intermediae its ends.
In testunony whereof I affix my signature.
