Description

Kombinert trykkutjevningsventil og tilbakeslagsventil Combined pressure equalization valve and non-return valve

for .væsker, særlig i forbindelse med varmtvannsberedere. for liquids, especially in connection with water heaters.

Foreliggende oppfinnelse angår en kombinert trykkutjevningsventil og tilbakeslagsventil for væsker, særlig i forbindelse, med væskebeholdere slik som varmtvannsberedere som opp-varmes med elektrisitet, damp, gass eller varmt vann og som står under direkte trykk fra hoyere-liggende vannmagasin eller trykkbe-holdere, hvor det er nodvendig med en trykkutjevningsventil for til-bakeføring av det ved oppvarming av berederen ekspanderende vann til vanntilforselsledningen, og hvor tilbakeslagsventilen skal hindre at beholderen tommes for sitt varme vann hvis det blir brudd på vanntilforselsledningen. Denne kombinerte ventil er forsynt med ett ventilsete og ett ventll-legeme som er anordnet i et.ventilhus, og Kfr. kl. 47g<1->15/04 som er'fritt bevegelig* i .en : sering og har en svak oppdrift i væsken. The present invention relates to a combined pressure equalization valve and non-return valve for liquids, particularly in connection with liquid containers such as water heaters which are heated with electricity, steam, gas or hot water and which are under direct pressure from higher-lying water reservoirs or pressure containers, where it is necessary to have a pressure equalization valve to return the water that expands when the boiler is heated to the water supply line, and where the non-return valve is to prevent the container from being emptied of its hot water if there is a break in the water supply line. This combined valve is provided with one valve seat and one valve body which is arranged in a valve housing, and Cfr. at 47g<1->15/04 which is 'freely movable* in .a : sering and has a slight buoyancy in the liquid.

Hensikten med oppfinnelsen, er" å tilveiebringe en ny og fordelaktig utforming av en slik kombinert ventil som sam- The purpose of the invention is to provide a new and advantageous design of such a combined valve which together

Dette oppnås i folge oppfinnelsen ved at ventil-.- ri' huset er forsynt med en gjenget spindel som har en anleggsflate for ventillegemet og som ved innskruing presser ventillegemet mot ventil--setet og derved gjor ventilen anvendbar som stoppekran. ,På .denne ' måte vil ventillegemet lett folge sterke strømninger i væsken og ut- This is achieved according to the invention by the valve body being provided with a threaded spindle which has a contact surface for the valve body and which, when screwed in, presses the valve body against the valve seat and thereby makes the valve usable as a stopcock. In this way, the valve body will easily follow strong flows in the liquid and

Fortrinnsvis har ventillegemet form av en kule Preferably, the valve body has the shape of a ball

og har litt mindre spesifikk vekt enn væsken, men ventillegemet kan ha storre spesifikk vekt enn væsken og for å tilveiebringe oppdriften er det da anbrakt f.eks. en fjær mellom ventillegemet og ventilsetet. and has a slightly lower specific weight than the liquid, but the valve body can have a greater specific weight than the liquid and to provide buoyancy, it is then placed e.g. a spring between the valve body and the valve seat.

Et utforelseseksempel på oppfinnelsen skal for-klares nærmere under henvisning til tegningen, som viser et aksialt An embodiment of the invention will be explained in more detail with reference to the drawing, which shows an axial view

Ventilhuset 1 har som det fremgår av tegningen en labyrint-gj-ennomgang med et innlop 2, og en gjennomstrømnings vei gjennom ventilsetet 4. På utlopssiden av ventilsetet er anordnet et ventillegeme 5 1 'form av en kule av et materiale med litt mindre egenvekt enn væsken som skal passere ventilen, og ventillegemet er styrt med klaring i et sylindrisk rom 8 i ventilhuset som oventil "' As can be seen from the drawing, the valve housing 1 has a labyrinth passage with an inlet 2, and a flow path through the valve seat 4. On the outlet side of the valve seat, a valve body 5 1 is arranged in the shape of a ball of a material with a slightly lower specific gravity than the liquid to pass the valve, and the valve body is guided with clearance in a cylindrical space 8 in the valve housing as above "'
