Opfindelsen angår en fluidumventil af den i indledningen til krav 1 nævnte art.The invention relates to a fluid valve of the kind mentioned in the preamble of claim 1.

En ventil af denne art kendes fra den britiske patentansøgning 2 012 920A. Ved denne kendte ventil består tætnings-organet af en ring, der er fikseret i forhold til ventilens 5 spindel og muffe, og som i ventilens lukkede stilling luk ker udløbsporten i spindlen. Ved denne kendte konstruktion er tætningsringen anbragt i en sådan stilling, at den aldrig ligger i strømningsvejen gennem ventilen. Tætningsringen er anbragt på muffens yderside 180° fra muffens 10 indløbsport, så vand kan derfor aldrig løbe gennem tætningen.A valve of this kind is known from British Patent Application 2 012 920A. In this known valve, the sealing means consists of a ring which is fixed relative to the spindle and sleeve of the valve 5 and which in the closed position of the valve closes the outlet port in the spindle. In this known construction, the sealing ring is placed in such a position that it never lies in the flow path through the valve. The sealing ring is located 180 ° from the inlet port of the sleeve 10, so water can never pass through the seal.

Formålet med opfindelsen er at angive en fluidumventil, som medfører en endnu mere pålidelig og sikker tætning, og dette formål opnås ifølge opfindelsen ved, at fluidumventilen er udformet som angivet i den kendetegnende del af krav 1.The object of the invention is to provide a fluid valve which results in an even more reliable and safe seal, and this object is achieved according to the invention in that the fluid valve is designed as defined in the characterizing part of claim 1.

15 Fordelen herved er, at den i trykkammeret mellem tætningslegemet og huset tilvejebragte tætningskraft, som presser tætningsorganets rundtgående ring i tætnende anlæg mod spindlen, er direkte proportional med væsketrykket i spindelens indre. Der sikres således en fuldstændig tæt 20 tætning, når spindlen er i lukket stilling.The advantage of this is that the sealing force provided in the pressure chamber between the sealing body and the housing, which presses the circumferential ring of the sealing member in sealing abutment against the spindle, is directly proportional to the fluid pressure in the interior of the spindle. Thus, a completely tight seal is secured when the spindle is in the closed position.

Opfindelsen beskrives nærmere i det følgende under henvisning til tegningen, hvor fig. 1 er et delvis, langsgående snit i en ventil ifølge opfindelsen, og 25 fig. 2 er et snit langs planet 2-2 i fig. 1.The invention will now be described in more detail with reference to the drawing, in which 1 is a partial longitudinal section of a valve according to the invention; and FIG. 2 is a section along the plane 2-2 of FIG. First

Som vist på tegningen har et i det væsentlige cylindrisk hus 230 et udadragende, cylindrisk parti 232, som danner ventilkonstruktionens udløb. Et husparti 234 kan udvendigt være gevindskåret til optagelse af en hætte, som 5 tjener til at fastholde ventilkonstruktionen i huset.As shown in the drawing, a substantially cylindrical housing 230 has an outwardly extending cylindrical portion 232 which forms the outlet of the valve assembly. Externally, a housing portion 234 may be threaded to receive a cap which serves to retain the valve assembly in the housing.

Husets nedre ende kan have en nedadragende passage 236, der tjener som indløb for ventilen.The lower end of the housing may have a downwardly extending passage 236 which serves as an inlet for the valve.

I huset 230 findes en ventilkonstruktion omfattende en spindel, der som helhed er betegnet 238, og en muffekonstruktion, der som helhed er betegnet 240. Spindlen har 10 en ydre del 242, der tjener som monteringsorgan for et passende driftsorgan. På den ene side af en O-ring 246 findes en skulder 244 til fastholdelse af O-ringen. En noget større skulder 248 er anbragt på 0-ringen 246's modsatte side. Spindlen er hul og har en udløbsport 250, 15 der er vist mere detaljeret i fig. 2. Spindlen 238*3 nedre ende kan have et passende indløb 252. Vand vil således strømme gennem spindlen fra indløbet 252 ind i spindlens i det væsentlige hule indre, ud af udløbsporten 250 og derfra til husets udløb 232, forudsat at spindlen 20 er roteret fra den i fig. 1 viste lakkede stilling til en åben stilling.In the housing 230 there is a valve structure comprising a spindle designated as a whole 238 and a sleeve structure designated as a whole 240. The spindle 10 has an outer part 242 which serves as a mounting means for a suitable operating means. On one side of an O-ring 246 is a shoulder 244 for retaining the O-ring. A somewhat larger shoulder 248 is disposed on the opposite side of the 0-ring 246. The spindle is hollow and has an outlet port 250, 15 which is shown in more detail in FIG. 2. The lower end of the spindle 238 * 3 may have a suitable inlet 252. Thus, water will flow through the spindle from the inlet 252 into the substantially hollow interior of the spindle, out of the outlet port 250 and thence to the outlet 232 of the housing, provided that the spindle 20 is rotated. from the one shown in FIG. 1 to an open position.

Muffekonstruktionen omfatter en i det væsentlige cylindrisk muffedel 254, der er anbragti huset, og en hættelignende konstruktion 256, hvis udadrettede skulder 258 ligger over huset 230’s ydre ende. Muffedelen og hætten kan passende 25 holdes sammen til dannelse af en enhedskonstruktion, f.eks. ved hjælp af på muffedelen udformede fremspring 260, som passer i dertil svarende indhak 262 i hætten. Under alle omstændigheder er det vigtigt, at der tilvejebringes en enhedsmuffekonstruktion, der på enkel måde kan anbringes 30 og fastgøres på huset og som tillader spindlen at rotere, men ikke at bevæge sig frem og tilbage.The sleeve assembly comprises a substantially cylindrical sleeve portion 254 disposed within the housing and a cap-like structure 256, the outward shoulder 258 of which extends beyond the outer end of the housing 230. Suitably, the sleeve member and cap can be held together to form a unit structure, e.g. by means of projections 260 formed on the sleeve part, which fit into corresponding notches 262 in the cap. In any case, it is important to provide a unitary sleeve assembly which can be easily mounted and secured to the housing and which allows the spindle to rotate but not to reciprocate.

3 I hætten 256's indre findes en rille 264 til optagelse af skulderen 248 på spindlen og derved hindre spindlen i at bevæge sig frem og tilbage i forhold til muffen. Muffekonstruktionen har et par i indbyrdes afstand beliggende, 5 udadvendende riller til optagelse af tætningsringe 266 og 268 således, at muffekonstruktionens modstående ender effektivt tætnes mod husets indre. Muffekonstruktionen kan omfatte en udløbsport 267 på linie med husets udløb 232.3 In the interior of the cap 256 there is a groove 264 for receiving the shoulder 248 on the spindle, thereby preventing the spindle from moving back and forth with respect to the sleeve. The sleeve assembly has a pair of spaced apart, 5 outwardly extending grooves for receiving sealing rings 266 and 268 such that the opposite ends of the sleeve assembly are effectively sealed to the interior of the housing. The sleeve assembly may comprise an outlet port 267 in line with the housing outlet 232.

Det stationære tætningsorgan tilvejebringer den oven for 10 nævnte lukning af ventilen. Tætningsorganet omfatter et legeme 270 og et parti 272 eksempelvis en rundtgående ring, der strækker sig gennem en åbning 274 i muffekonstruktionen. Legemet er i plansnit ret rektangulært, men har en cylindrisk krumning, således at det passer til muffens ydre. Legemet 13 passer faktisk i en cylindrisk udskæring 276 i muffens ydre, og der kan være en inddrejet, periferisk tætnings flange 278, som passer i et dertil svarende indhak 280, hvorved tætnings-organet fastholdes på muffens ydre. Et antal vulster 282 strækker sig omkring legemets periferi og er i berøring 20 med huset 230's indre. Vulsterne danner den ydre afgrænsning for et trykkammer, der er dannet af en fordybning 284 i tætningsdelens legeme. Vand strømmer ind i tætningskonstruktionen fra spindlens udløbsport 250 og fylder fordybningen 284, hvilket skaber et indadrettet tryk på tæt-25 ningspartiet 272, således at tætningspartiet påvirkes til tætnende anlæg mod spindlen.The stationary sealing means provides for the closure of the valve mentioned above. The sealing means comprises a body 270 and a portion 272, for example, an annular ring extending through an opening 274 in the sleeve structure. The body, in plan section, is quite rectangular, but has a cylindrical curvature to fit the exterior of the sleeve. The body 13 actually fits in a cylindrical cut-out 276 in the exterior of the sleeve, and there may be a retracted peripheral seal flange 278 which fits into a corresponding notch 280, whereby the sealing member is retained on the exterior of the sleeve. A plurality of beads 282 extend around the periphery of the body and are in contact 20 with the interior of the housing 230. The beads form the outer boundary of a pressure chamber formed by a recess 284 in the body of the sealing member. Water flows into the sealing structure from the spindle outlet port 250 and fills the recess 284, which creates an inward pressure on the sealing portion 272 so that the sealing portion is actuated for sealing abutments against the spindle.

Det er en væsentlig fordel, at tætningsorganet ligger uden for gennemstrømningspassagen fra muffens indløb til spindlens indløb og derpå gennem den hule spindel gennem dennes udløb til muffens udløb. På intet tidspunkt strømmer vand gennem 30 tætningskonstruktionens centrum. Tætnihgsorganet vil være i berøring med vand, men vil aldrig være udsat for et sådant tryk, at det kan fjernes fra dets stationære stilling.It is a significant advantage that the sealing means is outside the flow passage from the inlet of the sleeve to the inlet of the spindle and then through the hollow spindle through its outlet to the outlet of the sleeve. At no time does water flow through the center of the sealing structure. The sealing member will be in contact with water, but will never be subjected to pressure to be removed from its stationary position.

DK 154909BDK 154909B

It Tætningsorganet er heller ikke udsat for et tryk, der kan forårsage, at det presses udad fra dets stilling på muffen, således at den bevægelige spindel ville kunne skære eller slide tætningsorganet. Det er særligt fordelagtigt at an-5 vende selve vandtrykket til at frembringe et fast tætnende anlæg mod spindlen.Also, the sealing member is not subjected to a pressure which may cause it to be pressed outward from its position on the sleeve so that the movable spindle could cut or wear the sealing member. It is particularly advantageous to use the water pressure itself to produce a fixed sealing system against the spindle.

Ventilkonstruktionen ifølge opfindelsen er anvendelig i køkken-, toilet- og badeværelseshaner, hvor der anvendes separate ventiler til regulering af strømmen af varmt og koldt vand. Ventilen er ikke begrænset til sådanne an-10 vendelser, men det har vist sig, at den er særlig velegnet til sådant brug.The valve construction according to the invention is applicable in kitchen, toilet and bathroom faucets, where separate valves are used to control the flow of hot and cold water. The valve is not limited to such applications, but it has been found to be particularly suitable for such use.
