WZ Series Ekyuma ekituula OS&Y gate valve
Okunnyonnyola:
WZ Series Metal seated OS&Y gate valve ekozesa ductile iron gate nga muno mulimu empeta ez’ekikomo okukakasa nti ekwata amazzi. Valiva y’omulyango ya OS&Y (Outside Screw and Yoke) esinga kukozesebwa mu nkola z’okufuuwa amazzi ezikuuma omuliro. Enjawulo enkulu ku vvaalu y’omulyango eya NRS (Non Rising Stem) eya bulijjo eri nti ekikolo n’ekikolo biteekebwa ebweru w’omubiri gwa vvaalu. Kino kyangu okulaba oba vvaalu eggule oba eggaddwa, anti kumpi obuwanvu bwonna obw’ekikolo bulabika nga vvaalu eggule, ate ng’ekikolo tekikyalabika nga vvaalu eggaddwa. Okutwaliza awamu kino kyetaagisa mu nkola ez’ekika kino okukakasa okufuga okw’amangu okulaba embeera y’enkola

Ekintu eky'enjawulo:
Wedge nut:Wedge nut ekoleddwa mu copper alloy nga erina obusobozi bw’okusiiga nga ekuwa okukwatagana okulungi n’ekikolo ky’ekyuma ekitali kizimbulukuse.
Wedge:Wedge ekoleddwa okuva mu kyuma ekinywevu nga kiriko empeta za ffeesi ez’ekikomo alloy ezikolebwa mu machnined okutuuka ku fine surface finish okukakasa optimum contact seal ne body seat rings.The wedge face rings zikolebwa bulungi machined era firmly secured ku wedge.The guides mu wedge okukakasa uniform closure regardless of high pressures.The wedge has a large throught bore housing for the stem that ensures no stagnant amazzi oba obucaafu busobola okukung’aanya.Ekiwujjo kikuumibwa mu bujjuvu n’ekizigo kya fusion bonded epoxy.
