Abstract

A thermostatic valve used for mixing hot and cold water. The valve comprises inlet openings (2, 3) for hot and cold water, of the conventional type, a control element (5), arranged movably inside the valve body, which is preferably designed in the form of a piston and allows the flow of hot and cold water in the adjusted ratio, and a mixing chamber (7) out of which leads an outlet opening (4). The object of the invention is to avoid functional problems with the movable control element which result primarily from the deposition of lime contained in the water in the confined movement cavities which produce a seal. For this purpose, the control element (5) is sealed to the valve body (1) by an elastic membrane (14), which is attached to both the control element and to the valve body, but whose elasticity permits the required control element movements.

Opfindelsen angår en termostatventil til blanding af varmt og koldt vand og af den art, som har tilgangsåbninger for henholdsvis varmt og koldt vand samt et i det væsentlige ringformet reguleringselement, der på 5 lignende måde som et stempel er forskydeligt i et aflangt hulrum indvendig i det omgivende ventilhus, hvilket reguleringselement er således udformet, at det ved sin aksiale forskydning regulerer åbningstværsnittet af drøvleåbninger for henholdsvis koldt og varmt vand og 1 o lader de indstillede mængder af varmt og koldt vand strømme ind i et efter elementet placeret blandekammer og derfra til en afgangsåbning, og hvor et for temperaturen af bl åndingsvandet udsat termostatelement påvirker reguleringselementet aksialt, og hvor der mellem regule-15 ringselementet og ventilhuset og desuden mellem varmt-vandstilgangsåbningen og koldtvandstilgangsåbningen er en ringformet, tætnende membran, der tillader bevægelser af reguleringselementet og skiller det kolde vand fra det varme vand.The invention relates to a thermostatic valve for mixing hot and cold water and of the kind having access openings for hot and cold water, respectively, and a substantially annular control element, which in a manner similar to a piston is displaceable in an elongated cavity inside it. surrounding valve housing, which control element is designed such that by its axial displacement, it regulates the opening cross-section of throttle openings for cold and hot water, respectively, and allows the set amounts of hot and cold water to flow into a mixing chamber located after the element and from there to a discharge opening. and wherein a thermostat element exposed to the temperature of the breath water affects the control element axially, and where there is an annular, sealing diaphragm between the control element and the valve body, and also between the hot-water supply opening and the cold-water supply opening, which allows movement of the control element and separates it. d from the hot water.

20 En sådan termostatventil kendes fra dansk patent nr. 88087, hvor membranen er en i ventilhuset lejret tætningsring, der presser ind mod ydersiden af reguleringselementet. Tætningsringen er forholdsvis stiv og vil, i det mindste ved større reguleringsbevægelser, 25 glide hen over reguleringselementets yderside. En mangel ved en sådan termostatventil består i, at aflejringen af kalk fra ledningsvandet på ventilelements yderside i området omkring membranen kan forringe ventilens funktionsduelighed og kan til sidst endog gøre den ubruge-30 lig. Selv små ansamlinger af forureninger påvirker ventilens funktion.Such a thermostat valve is known from Danish Patent No. 88087, wherein the diaphragm is a sealing ring enclosed in the valve housing which presses against the outside of the control element. The sealing ring is relatively rigid and, at least with greater control movements, will slide over the outside of the control element. One shortcoming of such a thermostatic valve is that the deposition of lime from the tap water on the outside of the valve element in the area around the membrane can impair the operation of the valve and may eventually render it unusable. Even small accumulations of contaminants affect the functioning of the valve.

5 Nærværende opfindelse tager sigte på at angive en termostatventil, som ved anvendelse af en elastisk membran opviser en særlig enkel og økonomisk fordelagtig ! konstruktion, og hvor de ovenfor nævnte mangler, som be-tinges af kalkaflejringer, samtidig er undgået.The present invention aims to provide a thermostatic valve which, when using an elastic membrane, exhibits a particularly simple and economically advantageous method. construction, and where the above-mentioned defects, which are conditioned by lime deposits, are simultaneously avoided.

10 Med opfindelsen skal der tilvejebringes en termo statventil, som i øvrigt fungerer på kendt måde, men hvor tætningen mellem det bevægelige reguleringselement og ventilhuset er udformet således, at aflejring af kalk ikke giver nogen nævneværdig ulempe.The invention provides a thermostatic valve, which otherwise functions in a known manner, but in which the seal between the movable control element and the valve housing is designed such that lime deposition does not present any significant disadvantage.

15 Med henblik på at opnå dette er opfindelsen ejen dommelig ved, at reguleringselementet er rørformet med i store træk form som en garntrisse og har skråt udadrettede flanger, at membranen er indsat i en V-formet fordybning på reguleringselementet og er indsat på tilsva-20 rende vis i ventilhuset, at drøvleåbningerne er udformet mellem de mod membranen vendende sider af flangerne og på ventilhuset beliggende, ringformede skuldre, og at membranens radiale dimension er større end den radiale dimension af flangerne regnet fra reguleringselementets 25 cylindriske midterdel til drøvleåbningerne .In order to achieve this, the invention is itself doomed in that the control element is tubular in large form as a yarn pulley and has obliquely outward flanges, that the diaphragm is inserted into a V-shaped recess on the control element and is inserted on the equivalent of 20. show, in the valve body, that the throttle openings are formed between the faces facing the membrane and the annular shoulders located on the valve body, and that the radial dimension of the diaphragm is greater than the radial dimension of the flanges from the cylindrical central portion of the control element to the throttle openings.

Med membranen og reguleringselementets dimensionering opnås endvidere, at eventuelle trykstød i vandledningen bevirker en drøvling på det sted, hvor det højere tryk optræder. Konstruktionen ifølge opfindelsen 30 kan således delvis også fungere som pressorstat.Furthermore, with the diaphragm and the control element sizing it is possible that any pressure shocks in the water line cause a swirling at the place where the higher pressure occurs. Thus, the structure of the invention 30 may also partially function as a pressor state.

Opfindelsen forklares nærmere med henvisning til tegningen, der viser et længdesnit gennem en termostatventil ifølge opfindelsen.The invention is further explained with reference to the drawing which shows a longitudinal section through a thermostat valve according to the invention.

Tallet 5 henviser til et reguleringselement, der i lighed med et stempel er aksialt forskydeligt i 5 ventilhuset.3 for hot and cold water respectively. A discharge port 4 for the mixing water is formed at the bottom of the valve. The number 5 refers to a control element which, like a piston, is axially displaceable in the valve body.

Reguleringselementet har i det væsentlige form som en garntrisse, og ved sine ender har det skråt udadrettede flanger 5a og 5b, som sammen med ventilhuset danner ringformede drøvleåbninger 6a og 6b for hen-10 holdsvis det varme og kolde vand. Reguleringselementet 5 er på sin venstre ende påvirket af en skruefjeder 12 og på sin højre ende af et termostatelement 8, som på kendt måde trækker sig sammen aksialt ved faldende temperatur og udvider sig aksialt ved stigende temperatur.The control element is essentially like a yarn, and at its ends it has obliquely outward flanges 5a and 5b which together with the valve housing form annular throttle openings 6a and 6b for the hot and cold water, respectively. The control element 5 is actuated at its left end by a coil spring 12 and at its right end by a thermostat element 8, which in a known manner contract axially at decreasing temperature and expand axially at increasing temperature.

15 Stillingen af termostatelementet 8 kan desuden påvirkes ved hjælp af et drej egreb 9, hvis spindel har et gevind 10, som indgriber i ventilhuset, så termostatelementet 8 forskydes ved drejning af grebet 9. Med henblik på at beskytte termostatelementet 8 mod beska-20 digelse er det monteret med en i forhold til fjederen 12 væsentlig stivere fjeder li. Indstillingspindlen er desuden tætnet i forhold til ventilhuset 1 ved hjælp af en O-ring 15.In addition, the position of the thermostat element 8 can be actuated by means of a rotary lever 9, the spindle having a thread 10, which engages the valve housing, so that the thermostat element 8 is displaced by turning the handle 9. In order to protect the thermostat element 8 from damage. it is mounted with a substantially stiffer spring 1 relative to the spring 12. In addition, the adjusting spindle is sealed with respect to the valve housing 1 by means of an O-ring 15.

Som det vil være fagmanden bekendt, fungerer ven-25 tilen på følgende måde.As will be known to those skilled in the art, the friend functions as follows.

Varmt vand strømmer til gennem tilgangsåbningen 2 og kommer gennem den ringformede drøvleåbning 6a ind i blandekammeret 7. Tilsvarende strømmer koldt vand gennem tilgangsåbningen 3 og gennem drøvleåbningen 6b 30 ind i et rum 16 ved ventilhusets ende og derfra videre gennem reguleringselementet 5 ind i blandekammeret 7.Hot water flows through the inlet opening 2 and enters through the annular throttle opening 6a into the mixing chamber 7. Similarly, cold water flows through the inlet opening 3 and through the throttle opening 6b 30 into a space 16 at the end of the valve housing and thereafter through the control element 5 into the mixing chamber 7.

Flangen 13 bevirker, at det tilstrømmende kolde og varme vand ikke rammer termostatelementet 8 direkte.The flange 13 causes the flowing cold and hot water not to directly hit the thermostat element 8.

Antager vandet i blandekammeret 7 f.eks. en for høj 35 temperatur, udvider termostatelemetet 8 sig og reducerer tilstrømningsåbningen 6a for det varme vand. Syn-Assume the water in the mixing chamber 7 e.g. at too high a temperature, the thermostatic network 8 expands and reduces the hot water inflow opening 6a. Vision-
