Description

Hydraulisk betjent klafftetningsring som fortrinnsvis er metallisk og befinner seg ved omkretsen av en avstengningsklaff.
Oppfinnelsen angår en hydraulisk betjent klafftetningsring for avstengnings-klaffer for varme medier der tetningsrin-gen ikke vibrerer selv ved store hastigheter.
Det er kjent metalliske tetningsringer
som er anordnet bevegelig ved omkretsen
av klaffskiver og som av trykket i mediet
trykkes til lukkende endestilling. Videre er
det kjent strupe- og avstengningsventiler
hvis ventilklaff løftes fra ventilsetet og
deretter dreies.
Ved slike konstruksjoner kreves det at
temperaturen for mediet ikke overskrider
visse normale grenser, da setepartiene i
ventilhuset ellers vil deformeres.
I henhold til oppfinnelsen har, slik det
fremgår av tegningen, en løs klafftetningsring 1 et steg 10, som holdes mellom to
styrelister 11, 12, som er festet til klaffskiven. Derved danner steget sammen med
styrelistene to kammere 5, 6, som er lukket ved hjelp av tre membraner 2, 3, 4, en
membran mellom steget og klaffskiven og
en mellom flensen 1 på klafftetningsringen
og hver av styrelistene 11, 12. Disse kammere kan på den ene eller annen side av-vekslende ved hjelp av kanalene 7, 8 mates
med pressluft eller et annet trykkmedium
for å trykke klafftetningsringen inn i setet
i huset eller for å løfte ringen fra setet.
Seteflaten er tilpasset kule- eller kjegle-
formen på seteflaten i huset. Enhver form-endring som oppstår på grunn av en høy eller vekslende temperatur kan ringen til-passes ved hjelp av det hydrauliske trykk hvorved tetningen mellom huset og klafftetningsringen tilveiebringes uten at den bevegelige klafftetningsring flagrer eller vibrerer når klaffen er åpen, ikke en gang når det strømmende medium har store hastigheter.

Claims (1)

  1. Hydraulisk betjent klafftetningsring, fortrinnsvis av metall, og anordnet ved omkretsen av en avstengningsklaff, karakterisert ved at klafftetningsringen har et steg (10) som holdes mellom to styrelister (11, 12) på klaffen, der steget sammen med styrelistene omslutter to kammere (5, 6) som er lukket ved hjelp av tre membraner (2, 3, 4), en membran mellom steget og klaffskiven og en membran mellom ring-flensen (1) og hver av styrelistene (11, 12) på klaffskiven (9), idet disse kammere på den ene eller annen side ved hjelp av ka-naler (7, 8) kan mates med trykkluft eller et annet trykkmedium.
