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, kryt a poklop sú zo sivej liatiny. Kuželka, sedlový krúžok a vodiace púzdro sú z korózievzdornej ocele. Pružina je z kremíkochrómovej 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 tlaku. Používa sa pre vodu, vodnú paru a vzduch, na zvláštnu požiadavku aj pre iné neagresívne prevádzkové látky. Rozsah nastaviteľnosti otváracích pretlakov je od 0,03 MPa do 1,6 MPa.
