Description
Den foreliggende oppfinnelse angår en kuleventil med konisk seteparti utformet som to koniske halvdeler med hull for gjennomløps-kanalen, så ventilen lett lar seg åpne for demontering av ventilens indre deler uten å behøve å avmonteres fra den ledning den er anordnet på. The present invention relates to a ball valve with a conical seat part designed as two conical halves with holes for the passage channel, so that the valve can easily be opened for disassembly of the valve's internal parts without having to be disassembled from the line on which it is arranged.
Oppfinnelsen består i at hver setehalvdel består av gummi og er utformet på sin ytterside med en godsfast, ringformet tetningsvulst, som forløper rundt hullet i setehalvdelen og ér konsentrisk med dette. Herved oppnås en betydelig forenkling ved fremstilling og sammenføyning av ventiler av den angitte art, idet det bare behøves å innføre tre elementer (kulekiken og de to setehalvdeler) i ventilhuset, samtidig som der allikevel oppnås fullgod tetning. The invention consists in that each seat half consists of rubber and is designed on its outer side with a solid, ring-shaped sealing bead, which extends around the hole in the seat half and is concentric with this. Hereby, a significant simplification is achieved in the manufacture and joining of valves of the specified type, since it is only necessary to introduce three elements (the ball socket and the two seat halves) in the valve housing, while at the same time a fully satisfactory seal is still achieved.
Oppfinnelsen vil bli nærmere beskrevet under henvisning til The invention will be described in more detail with reference to
tegningen. the drawing.
Fig. 1 viser en utførelsesform av kuleventilen perspektivisk Fig. 1 shows an embodiment of the ball valve in perspective
og delvis gjennomskåret, og and partially cut through, and
fig. 2 er et perspektivisk detaljriss som viser de to halvdeler av ventilsetet på fig. 1. fig. 2 is a perspective detail drawing showing the two halves of the valve seat in fig. 1.
Den viste kuleventil består av et ventilhus 1 med en gjennom-løpskanal 2 og en konisk utboring 3. I denne utboring er der anordnet to koniske setehalvdeler 21 som ligger an mot dens bunn og tilsammen danner sete for en kulekik 5. Setehalvdelene 21 består av gummi og er forsynt dels med hull 6 som korresponderer med gjennomløpskanalen 2, og dels med utvendige ringformede tetningsvulster 22 som er utformet i deres gods og forløper konsentrisk rundt hullet i hver sin halvdel. The ball valve shown consists of a valve housing 1 with a flow channel 2 and a conical bore 3. In this bore there are arranged two conical seat halves 21 which rest against its bottom and together form a seat for a ball valve 5. The seat halves 21 consist of rubber and is provided partly with hole 6 which corresponds to the passage channel 2, and partly with external annular sealing beads 22 which are formed in their goods and run concentrically around the hole in each half.
Oventil er utboringen 3 lukket med et lokk 11, som har et hull 12 for kulekikens spindel 13, som dreies med et håndtak 14. Til tetning At the top, the bore 3 is closed with a lid 11, which has a hole 12 for the spindle 13 of the ball valve, which is turned with a handle 14. For sealing
mellom lokket og henholdsvis spindelen og ventilhuset er der anbragt to tetningsringer 15 og 16, den første i en utvidelse 12a av hullet 12 og den annen i en utvidelse 3a av utboringen 3-between the lid and respectively the spindle and the valve housing, two sealing rings 15 and 16 are arranged, the first in an extension 12a of the hole 12 and the second in an extension 3a of the bore 3-
Mellom husets koniske utboring og ytterflaten av de to setehalvdeler foreligger der en viss klaring for å gi en begrenset bevegelighet og kompensere for målforskjeller i produksjonen. Denne bevegelighet er ønskelig fordi tetningsvulstene 22 derved ikke bare virker tettende mellom ventilhuset og setehalvdelene, men dessuten utøver en kraft på setehalvdelene slik at disse blir presset tettende mot kulekiken. There is a certain clearance between the housing's conical bore and the outer surface of the two seat halves to provide limited mobility and compensate for differences in dimensions in production. This mobility is desirable because the sealing beads 22 thereby not only act as a seal between the valve housing and the seat halves, but also exert a force on the seat halves so that they are pressed sealingly against the ball bearing.
