Abstract

Zawór zwrotny posiada korpus (1) zaworu, element (2) zamykający wyposażony w trzpień (3), uszczelkę (4), sprężynę (5) dopychającą element (2) zamykający oraz prowadnicę (6) trzpienia elementu (2) zamykającego. Oba trzpienie (3) elementu (2) zamykającego usytuowane są w prowadnicach (6) trzpienia (3) elementu (2) zamykającego, a prowadnice (6) trzpienia (3) elementu (2) zamykającego stanowią części kierownic (7) strumienia. Kierownice (7) strumienia wykonane są z materiału podlegającego precyzyjnemu formowaniu. Kierownica (7) strumienia posiada formę ringu (8), wewnątrz którego posadowiona jest prowadnica (6) trzpienia (3) elementu (2) zamykającego. Prowadnica (6) trzpienia (3) elementu (2) zamykającego posiada zaokrąglone krawędzie. Element (2) zamykający jest elementem dwudzielnym, który stanowią grzybek (9) i pokrywa(10). Pomiędzy grzybkiem (9) i pokrywą (10) znajduje się uszczelka (4). Pokrywa (10) posiada ścięcie. Powierzchnia komory korpusu (1) zaworu w miejscu przylegania do niej uszczelki (4) usytuowana jest pod kątem w stosunku do uszczelki (4).The check valve has a valve body (1), a closing element (2) equipped with a stem (3), a gasket (4), a spring (5) pushing the closing element (2) and a guide (6) of the closing element stem (2). Both mandrels (3) of the closing element (2) are located in the guides (6) of the mandrel (3) of the closing element (2), and the guides (6) of the mandrel (3) of the closing element (2) are part of the flow guides (7). The flow blades (7) are made of a material that undergoes precise forming. The stream guide (7) has the form of a ring (8), inside which a guide (6) of the stem (3) of the closing element (2) is mounted. The guide (6) of the mandrel (3) of the closing element (2) has rounded edges. The closing element (2) is a bipartite element, which is a mushroom (9) and a cover (10). There is a gasket (4) between the plug (9) and the cover (10). The cover (10) has a chamfer. The surface of the valve body chamber (1) in the place where the seal (4) adheres to it is located at an angle to the seal (4).
