Abstract

The valve is of robust construction made in thermosetting plastic such as phenol or cresol-formaldehyde resin or furan resin to withstand temperatures up to 170 deg.C, and abrasion due to flow of medium. A central shaft of metal is threaded at each end and carries the heavy moulded plastic plate which is circular in form with edges chamfered to seal against the valve seating. The latter is formed inside the main body which butts against the two pipe ends. To strengthen the shaft in resisting torque when turning to open or close, the plate has an insert jacket with cam and adjusting spring. The shaft projects through a circular housing integral with body which carries a central bush and guide plates for manually operated handle.

Disadvantage of this Ringp.bsperrlrlappen, d: u> h them at higher temperatures and stresses abraciven sov / ie not eiii c 'e L et st v at Lor.ungsrnitteloinwirkungen e rc can s'.'.

i)er Erfindung liegt die Aufgabenstellung zugrunde, robuste, hochkoriocionsbert'indige, mechanisch beanspruchbare Absreri'Izlappen zu verwenden ait gleichzeitig höherer Temperaturbeanspruchungsgrenze·i) the invention is based on the object of providing robust, highly coordinated, mechanically stressable barrier flaps to be used at the same time higher temperature stress limit

Eo wurde nunmehr eine Hingabsperrklappe gefunden, die aus einem Duroplast, bsitr~aelsv:eioe aus Phenol- üder Kresolformaldehydharz oder Furanharz, in K.5Esivbauv;eise besteht, für Temperaturbeanspruchungen bis 1?0 C bei gleichzeitiger abrasiver Beanspruchbarkeit durch das strömende Medium.Eo a shut-off valve has now been found, which is made of a thermoset, bsitr ~ aelsv: egg made of phenol, cresol formaldehyde resin or furan resin, in K.5 Esivbauv; eise exists, for temperature loads up to 1? 0 C with simultaneous abrasive stress due to the flowing medium.

Diese Absperrklappen können gegenüber den bekannten Ringabsperrklappen nicht durch Werkstoffaustausch erhalten werden, sondern haben zugleich eine neue Konstruktion für Absperrklappen erfordert.These butterfly valves cannot, compared to the known ring butterfly valves can be obtained by exchanging materials, but at the same time have a new one Requires construction for butterfly valves.

Gegenstand der Erfindung sind Ringabsperrklappen für Rohrleitungen für Gas- und Flüssigkeitstransport, dadurch gekennzeichnet, daß diese auf einer metallischen Mitnehmerwelle aufgebaut (1) in Massivbauv/eise Platten aus Phenolfortr.alaehydharz, Kresolformaldehydharz oder Furanharz (2) tragen, wobei vermittels einer in den Duroplast eingelassenen H::lse (j>) mit Nocken (^) kunststoffseitig und einer Passfeder (5) gegen die Mitnehmerwelle hin Übertragung der Drehnomente erfolgt.The invention relates to ring shut-off valves for pipelines for gas and liquid transport, characterized in that they are built on a metallic drive shaft (1) in solid construction and bear plates made of phenol formaldehyde resin, cresol formaldehyde resin or furan resin (2), whereby one in the thermoset recessed H :: sleeve (j>) is effected with cams (^) plastic-side and a fitting key (5) against the cam shaft through the transmission Drehnomente.

Die erfindungsgemäße Ringabsperrklappe kann zwischen die Rohrleitung geflanscht werden.The ring butterfly valve according to the invention can be flanged between the pipeline will.
