Description

Hydraulisk betjent klafftetningsring som fortrinnsvis er metallisk og befinner seg ved omkretsen av en avstengningsklaff. Hydraulically operated flap seal ring which is preferably metallic and located at the periphery of a shut-off flap.

Oppfinnelsen angår en hydraulisk betjent klafftetningsring for avstengnings-klaffer for varme medier der tetningsrin-gen ikke vibrerer selv ved store hastigheter. The invention relates to a hydraulically operated flap sealing ring for shut-off flaps for hot media where the sealing ring does not vibrate even at high speeds.

Det er kjent metalliske tetningsringer Metallic sealing rings are known

som er anordnet bevegelig ved omkretsen which is arranged movable at the circumference

av klaffskiver og som av trykket i mediet of flap discs and as of the pressure in the medium

trykkes til lukkende endestilling. Videre er is pressed to the closing end position. Further is

det kjent strupe- og avstengningsventiler the known throttling and shut-off valves

hvis ventilklaff løftes fra ventilsetet og whose valve flap is lifted from the valve seat and

deretter dreies. then rotated.

Ved slike konstruksjoner kreves det at In the case of such constructions, it is required that

temperaturen for mediet ikke overskrider the temperature of the medium does not exceed

visse normale grenser, da setepartiene i certain normal limits, then the seat parts i

ventilhuset ellers vil deformeres. otherwise the valve housing will be deformed.

I henhold til oppfinnelsen har, slik det According to the invention has, so it

fremgår av tegningen, en løs klafftetningsring 1 et steg 10, som holdes mellom to appears from the drawing, a loose flap sealing ring 1 a step 10, which is held between two

styrelister 11, 12, som er festet til klaffskiven. Derved danner steget sammen med guide strips 11, 12, which are attached to the flap disc. Thereby forming the step together with

styrelistene to kammere 5, 6, som er lukket ved hjelp av tre membraner 2, 3, 4, en the guide strips two chambers 5, 6, which are closed by means of three membranes 2, 3, 4, a

membran mellom steget og klaffskiven og membrane between the step and the flap disc and

en mellom flensen 1 på klafftetningsringen one between the flange 1 of the flap sealing ring

og hver av styrelistene 11, 12. Disse kammere kan på den ene eller annen side av-vekslende ved hjelp av kanalene 7, 8 mates and each of the guide strips 11, 12. These chambers can be alternately fed on one side or the other by means of the channels 7, 8

med pressluft eller et annet trykkmedium with compressed air or another pressure medium

for å trykke klafftetningsringen inn i setet to press the flap sealing ring into the seat

i huset eller for å løfte ringen fra setet. in the house or to lift the ring from the seat.

Seteflaten er tilpasset kule- eller kjegle- The seat surface is adapted to ball or cone

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. the shape of the seat surface in the house. Any shape change that occurs due to a high or fluctuating temperature, the ring can be accommodated by the hydraulic pressure whereby the seal between the housing and the valve seal ring is provided without the movable valve seal ring fluttering or vibrating when the valve is open, not even when flowing medium has high speeds.

Claims (1)
