I-Valve ye-Butterfly ye-Offset kathathu yokulawula ukugeleza kwezimboni

I-geometry ye-offset kathathu inciphisa ukuxhumana okuqondile phakathi kwediski nesihlalo ngesikhathi sokuvula nokuvala. Ekusebenzeni kwangempela, lokhu kusiza ukunciphisa ukuguguleka ezindaweni zokuvala futhi kugcina i-torque yokusebenza izinzile, ngisho nangemva kwemijikelezo ephindaphindwayo. Uma kuqhathaniswa nama-valve e-butterfly avamile, ifaneleka kakhulu ezimweni zokushisa eziphakeme kanye nengcindezi lapho izivalo ezithambile zingasebenzi khona.

Kuhlelo lokuvala, ubuso besihlalo buqinile nge-alloy ye-Stellite®. Lokhu kuthuthukisa ukumelana nokugqwala, ukuguguleka, kanye nomthelela wokushisa. Indandatho yokuvala yensimbi elaminethiwe yakhelwe ukunikeza ukuxhumana okufanayo eduze kwesihlalo, okusiza ukugcina ukusebenza kokuvala okuqhubekayo. Izingxenye zokuvala ezisekelwe ku-graphite zisetshenziselwa ukuthuthukisa ukuphepha komlilo nokuvumela ukushintshwa okulula ngesikhathi sokulungiswa.

I-valve isebenzisa umgodi onengxenye eyodwa ukuqinisekisa amandla kanye nokudluliselwa kwe-torque okuthembekile. Ama-bearings akhethwa ukusingatha imithwalo ephezulu nokunciphisa ukuguguleka ngesikhathi sokusebenza. Uhlelo lokupakisha, oluhlanganiswe nezinto ze-graphite, luhloselwe ukulawula ukuvuza kwangaphandle nokuhlangabezana nezidingo ezivamile zokukhishwa kwegesi okusabalele ezisetshenziswa ezimbonini.

Ngokombono wokufakwa nokusebenza, ivalvu ifaka inkomba yesikhundla sangaphandle, okwenza kube lula ukuqinisekisa isimo sokuvuleka noma sokuvaleka ensimini. Izindawo zokuvala i-flange zenziwa ngomshini ukuze zigcine zibushelelezi, okusiza ekuthuthukiseni ukuthembeka kokuvala ekuxhumekeni kwamapayipi.

Lolu hlobo lwe-valve ye-butterfly e-offset kathathu luvame ukusetshenziselwa izinto ezifana namafutha aluhlaza, igesi yemvelo, umusi, uketshezi lwamakhemikhali, ama-asidi, amanzi olwandle, kanye namagesi ezimboni. Luphinde lusetshenziswe ezinhlelweni ze-geothermal, kumanethiwekhi okushisa esifunda, nakwezinye izinqubo ezihlobene namandla.
