Technický popis
Nadzdvihovacia páka slúži na preskúšanie činnosti za prevádzky. V telese je zavalcované sedlo, na ktoré dosadá uzatváracia kuželka. Kuželka je pritlačovaná do sedla tlačným hrotom. Silu vyvíja pružina. Poistný ventil pracuje samočinne tlakom pracovnej látky na kuželku. Smer prúdenia pracovnej látky je zdola pod kuželku. Výstup je vo vodorovnom smere.
Materiál
Teleso a kryt sú z uhlíkovej ocele. Poklop je zo sivej liatiny. Kuželka, sedlový krúžok a vodiace púzdro sú z korózievzdornej ocele. Pružina je z kremíkochromovej ocele.
Montáž
Na potrubie v kolmej polohe s prívodom pracovnej látky zo spodu. Smer prúdenia je určený šípkou na telese.
Použitie
Slúži ako bezpečnostný orgán, ktorý istí tlakové nádoby a iné zariadenia proti nedovolenému stúpaniu prevádzkového pretlaku. Používa sa pre vodu, vodnú paru a vzduch. Rozsah nastaviteľnosti otváracích pretlakov je od 0,03MPa do PMAXpodľa tabuľky rozmerov. Na zvláštnu požiadavku aj pre iné neagresívne prevádzkové látky.
