The present invention provides a removable cartridge for a fluid valve which includes a seat which is sealed with respect to the housing by means of a simple O-ring.
According to one broad aspect of the inventi.on, there is provided a removable cartridge for a fluid valve comprising a body member having an axial inlet opening at one end and at least one transverse outlet opening, a valve seat secured in said inlet opening, and valve means positioned in said body member for axial movement toward and away from said valve seat, said valve seat including a part extending beyond said body member adapted to receive an O-ring for providing a seal with a housing in which said cartridge is received, wherei.n said valve means includes a stem portion and a closure portion, said stem portion having male threads cooperating with female threads in said body member whereby rotation of said stem portion moves the valve means axially towards or away from said valve seat, said closure portion being rotatably mounted in said stem portion whereby said stem portion may be rotated with-out rotating said closure portion when it engages said valve seat, wherein said valve seat comprises an outer metallic portion having a first flat annul-ar seat and an inner portion of resilient material providing a second seat and wherein said valve means has an outer flat annular portion engageable with said first seat and a second spherically shaped portion engageable wi*h said second seat.
,s _ 1 _ ~ 3 According to another broad aspect of the invention -there is provided a removable cartrid~ for a ~ id valve cornpr;.sing a hody mf~m~er having an axial inlet openillg at one end and at least one transverse outle-t orening, a valve seat secured in said inlet opening, and valve means positionecl in sa;d hody member for axial movement -toward and away from saicl va]vc se~it, said valvf., scat includ~ g a part extending beyon(l said body mcmher adaptc(l to rece:i.ve an O-r:ing -for providing a seal with a housing in whicn said cartridge is received, wherein said valve means ;.ncludes a stem portion and a closure port:ion, said stem por-tion being secured in said body member for rotational movement but not translat-ional movement and having an internally threaded bore adapted to cooperate with an externally threaded rod on said closure portion, said closure portion being keyed to said body member to prevent it from rotating but to allow it to move longitudinally whereby rotation of said stem portion moves said closure por-tion towards or away from said valve seat, wherein said valve seat comprises an ou~er metallic portion having a first flat annular seat and an inner annular portion of resilient material providi.ng a second seat and wherein said valve means has an outer flat annular portion engageable with said first seat and a second spherically shaped portion engageable with said second seat.
The valve means may i.nclude a stem portion and a closure portion, the stem portion having male threads cooperating wi-th female threads in the body portion whereby rotation of tne stem portion moves the valve means axially towards or away ~rom the valve seat the closure portion being rotatably mounted in the stem portion whereby the stem portion may be rotated without -la-~; ', rotating the closure portion when it enyages the seat means.
Alternatively, the valve means may include a st~rn portion and a c]osure portion, the stem por-tion beincJ secured in the body member :Eor rota-tional movement bu-t not translat:ional movement and having an internal:ly threaded bore adapted to cooperate with an externally threaded rod on the closure portion.
The closure portion is keyed to the body member to preven-t it from rotating but to allow it to move longitudinally whereby rotation of the stem portion moves the closure portion towards or away from the valve seat.
As still another alternative, the valve means may include integral stem and closure portions, i.e. be a single piece.
In this case, however, the closure portion ro-tates on the valve seat.
The closure portion may have a spherically shaped surface for engagement with the seat means and, in one embodiment, the seat means comprises an outer metallic portion having a first flat annular seat and an inner annular portion of resilient material providing a second seat, in which case the valve means has an outer flat annular portion engageable wi.th the first seat and a second spherically shaped portion engageable ~ith the second seat.
The stem portion is preferably of brass, although it could be of stainless steel. The closure portion may be, Eor example, of brass or of plastic.
The invention will now be further descxibed in con~unction with the accompanying drawings, in which:
Figure 1 is a partially cross-sec-tioned v.iew oE a first embodiment according to the invention, Figure 2 is a par-tially cross-se~tioned view o~ a second embodiment according to the inven-tion, Fiyures 3 and 4 illus-trake alternative constructions of the valve means, Figure 5 is a partially cross-sectioned view of a third embodiment according to the invention, Figure 6 is a partially cross-sectioned view of a fourth embodiment according to the invention, and Figure 7 is an enlarged cross-sectional view of a valve seat according to the invention.
Referring to Figure 1, a cartridge according to a first embodiment of the invention is generally indicated at 10. The cartridge 10 is receivable in a housing, only a portion of which is indicated at 12. The cartridge comprises a body member 14 having an axial inlet opening 15 at one end and at least one transverse outlPt opening 16. A valve seat 17 is removably secured in the inlet opening 15, as by a threaded connection 20. A valve means 21 is positioned in the body portion 14 for axial movement toward and away from the seat means 17, such movement being by virtue of the threads 23. That is, by rotating the stem 22, the threads 23 cause the valve means 21 to move toward or away from the seat 17. A handle, not shown, can be connected to the knurled portion 24 at the top of the stem 22.
The valve seat 17 extends beyond the body member 14 and has an O-rin~ 26 for providing a seal with the housing 12 in which the cartridge is received.
s~
The valve means 21 includes the stem portion 22 and a closure por-tion 27. The closure portion 27 iD rot~,ta~ly mounted on -the stem portior~ 22, as will be fur-ther discussed in connection with Fiyures 3 ana 4, whereby -the s-tern por-t:ion 22 may be rota-ted wi-thout rota-ting the c:Losure port:ion 27 when it engages the seat means 17.
In the Figure 1 ernbodiment, -the closure portion 27 preferably has a spherically shaped surface, as shown, for engagement with the valve seat 17.
The embodiment shown in Figure 2 functions in essentially the same manner as the Figure 1 embodiment, but the structure of the valve seat and closure means are slightly different. In this embodiment, the seat 17 includes an outer metallic portion 30 having a first flat annular seat 31 and an inner annular portion 32 of resilient material, such as vulcanized rubber, providing a second seat. The valve means has an outer flat a~ular ~rtio~ ~5 e~a~ea~e wi~h ~e irs~ sea~ 31 a~ a seccJ~d spherica~y shaped portion 36 engageable with t~2e second ~ea t . As in the Figure 1 en~odiment, turnlng the stem 22 moves the closure portion towards or away from the seat means.
Figure 3 illustrates, partially in cross-section, a valve means comprising a brass stem 22 and a plastic closure means 27. The plastic closure means 27 includes a head portion 40 which snaps into a similarly shaped opening in the lower end of stem 22. The fit is, of course, a loose fit so that the closure member 27 can spin freely with respect to the stem 220 In Fiyure 4, the closure member 27 is of brass, as .is the stem 22. In this ~ase, the closure member 27 i8 held i~ the end of the stem 22 by upset-ting the end portion 50 ~ -the stern so that it overlies the rib 51, preven-ting removal ~:~ the clo~ure member 27. Agai.n, of course, the closure member 27 must be free to rotate in the stem 22.
The Figure 5 embodiment differs from the embodiment of Figure 2 in that the stem portion 22 does not move longitudinally.
The stem portion 22 is retained in body member 14 by a lower annular lip on the stem portion and by a snap r.ing 54. The stem portion 22 is free to rotate and has an internally threaded bore 55 adapted to cooperate with an externally threaded rod portion 56 on the closure portion 27. The closure portion 27 has a key 60 which slides in a keyway 61 in the body member 14. The key prevents the closure portion from rotating but allows it to move longitudinally in the body member 14. Rotation of stem portion 22 causes the closure portion to move up or down longitudinally because of the threads 56.
The Figure 6 embodiment has the same type of valve seat and closure portion as Figure 2 except that the closure portion is .integral with the stem and therefor rotates as well as moving longitudinally~ This embodiment would be more subject to wear of the seat and closure member because of rubbing between them upon closing and opening.
Figure 7 is an enlarged cross-sectional view of a valve seat 17 showing a lip portion 63 on the outer metallic portion 30 of the seat. The lip 63 serves to retain the O-ring 26 during removal of the cartridge from the body member.
