Umnyango wezobuchwepheshe be-fluid we-BMG uhlinzeka ngezinhlobonhlobo zezingxenye nezisekelo zezinhlelo zobuchwepheshe obuketshezi kanye nezicelo ezijwayelekile zezimboni. Le mikhiqizo ihlanganisa ama-valve, ama-hydraulic hoses kanye nokufakwayo, ama-accumulators, amasilinda, izishintshi zokushisa, ama-hydraulic motors namapayipi adonsa amanzi, kanye namaphampu nezinsiza zamathangi.
Amavalvu abalulekile kuphothifoliyo yomkhiqizo we-BMG ahlanganisa i-InterApp Bianca ne-Desponia butterfly valves, anconyiwe ukuze asetshenziswe ngendlela ephumelelayo nephephile ekusetshenzisweni okufunwayo kokulawula ukugeleza kwemboni.
"I-valve butterfly emangelengele iklanyelwe ukuvala nokulawula uketshezi olubolayo kanye nezicelo ezihlanzekile," kusho u-Willie Lamprecht, i-BMG Fluid Technology Low Pressure Business Unit Manager. I-valve ye-butterfly ehlangene inezici ezinhle zokugeleza kanye nezidingo zokunakekelwa okuphansi, futhi iguquguquka kakhulu, iqinisekisa ukusebenza okuthembekile ngisho nasendaweni enzima kakhulu.
“Ngokungafani ne-valve yebhola, i-disc ye-butterfly valve ihlala ikhona ku-flow channel. Lokhu kusho ukuthi kungakhathaliseki ukuthi i-valve ikuphi, izobangela ukwehla kwengcindezi ekugelezeni. Amavalvu ebhola angasetshenziswa kuphela ukuzehlukanisa, kuyilapho amavalvu ovemvane angasetshenziswa ngokuphephile ukuze ahlukaniselwe futhi Alawule ukugeleza.
“Uma kuqhathaniswa nezinye izinhlobo, enye yezinzuzo zokusebenzisa i-valve uvemvane ejika kwesokudla iwumklamo olula omise okwe-wafer, izingxenye ezimbalwa, ukukhanda kalula kanye nokulungisa kancane.”
Ivalvu uvemvane ephakathi kwe-BMG ye-InterApp Bianca ifakwe ulayini we-PTFE oqinile, inempilo ende yesevisi, futhi ifanelekela uketshezi olubolayo nokugqwala kanye nezinhlelo zokusebenza lapho ubumsulwa bubaluleke kakhulu.
Lawa mavalvu asebenza kahle kakhulu aphakathi kwe-DN 32 ne-DN 900 ngosayizi futhi enziwe nge-ductile iron, carbon steel noma imizimba yamavalvu ensimbi engagqwali ukuze ahlangabezane nezidingo zazo zonke izimboni. Ama-valve ovemvane be-Bianca angahlelwa ngawodwa yi-BMG ukuze kuqinisekiswe ukusebenza okuthembekile nokuphepha okuphelele ezinhlelweni ezithile.
Isibonelo, ivalve ye-Bianca ethobela i-FDA (i-DN 50-DN 200) inediski yensimbi engagqwali epholishelwe isibuko kanye nomugqa we-PTFE ohlanzeke kakhulu ukuze kuqinisekiswe ukuphepha kokukhiqizwa kwezithako ezisebenzayo zemithi. Amavalvu e-Bianca anamadiski ahlanganiswe ne-PFA kanye nolayini we-PTFE anconyelwe ukusetshenziswa kwamakhemikhali okubola kakhulu.
Lolu chungechunge lwama-valve lusebenzisa ama-conductive discs akhethiwe ngokukhethekile kanye nezinto zokwenziwa kolayini, futhi futhi luhambisana nomyalelo wokuvikela ukuqhuma kwe-ATEX 94/9EG, okuqinisekisa ukusebenza okuphephile ezindaweni eziqhumayo.
Izici eziphawulekayo zochungechunge lwe-Bianca zifaka phakathi izihlahla eziphakeme, i-PFA disc overmolding ku-shaft, kanye nezimpawu ze-shaft shaft ezilayishwe impilo yonke, ukuqinisekisa ukutywinwa okuthembekile kwe-shaft okuyisisekelo kanye nokuvala uphawu kwe-shaft okuhlala isikhathi eside, ngisho nemijikelezo yokusebenza enokhahlo kanye namazinga okushisa aphezulu.
I-cavity lining ivimbela ukugeleza okubandayo endaweni yokuvala i-flange, ngaleyo ndlela yandise impilo yesevisi, kuyilapho uhlaka lwe-PTFE luhlanganiswe ne-PFA overmolded disc luqinisekisa ukungqubuzana okuphansi, ngaleyo ndlela kunwebe impilo yesevisi yesistimu. Ezinye izici zifaka umshini wangaphandle wokuvala shaft ukuvikela imbobo yentamo ye-valve kanye ne-robust self-lubricating kanye ne-bushing-free bushing. Amathegi evalvu yensimbi engenasici avumela ukulandeleka okugcwele.
I-BMG isitokwe ngezinhlobo eziningi zezingxenye eziqediwe ukuze inikeze izikhathi ezimfushane zokulethwa, ngisho nochungechunge lwe-Bianca olunosayizi omkhulu we-DN 900.
Ukusetshenziswa okujwayelekile kwamavalvu ovemvane be-Bianca ukukhishwa kwama-asidi nezincibilikisi ezimayini nodaka; ukucubungula okungeziwe embonini kawoyela negesi kanye nezinqubo ezonakalisa kakhulu embonini yensimbi. Lolu chungechunge lubuye lufanele ukwelashwa kwamanzi lapho ukungcola okuncane kakhulu okudingeka kugwenywe.
Amavalvu e-BMG e-InterApp Desponia kanye nesikhungo sovemvane se-Desponia Plus anomzimba oqinile kanye nomugqa oqinile we-elastomer, futhi aklanyelwe ukulungiswa okuphephile nokuthembekile koketshezi namagesi emikhakheni ehlukene.
Ama-valve e-Desponia atholakala ngosayizi ukusuka ku-DN 25 kuya ku-DN 1600 kanye nezingcindezi ezifika kubha engu-16, alungele izinhlelo zokusebenza ezihlukahlukene zezimboni. Lolu chungechunge lungahlinzeka ngemizimba ye-cast iron kanye ne-ductile iron valve.
Usayizi wochungechunge lwe-Desponia Plus uphakathi kwe-DN 25 ne-DN 600, ifanele izicelo zokucindezela okuphezulu kufika kubha engu-20, ifanele ukushisa okuphezulu noma izinhlelo zokusebenza ze-vacuum kanye nenqubo yokuzenzakalela. Lolu chungechunge lungahlinzeka ngemizimba yama-valve eyenziwe nge-ductile iron, iron cast noma insimbi engagqwali.
I-liner ne-butterfly plate yalolu chungechunge idlala indima ebalulekile ku-valve uvemvane olulayini olunwebekayo, ngoba yizona kuphela izingxenye ezimbili ezithintana noketshezi. Ama-liner e-Flucast® afanele ukusetshenziswa kwe-abrasive futhi ahambisana nemithetho ye-FDA ne-EU.
Izici eziphawulekayo zalolu chungechunge zihlanganisa indlela yangaphandle yokuvala i-shaft evikela imbobo yentamo ye-valve kanye nomklamo wentamo ende ovumela ukufakwa kwamapayipi. I-gasket engaguquki ihlinzeka ngokuvikeleka ekuqhumeni, futhi i-O-ring yakhiwe ephasejini le-shaft ukuze ibe yingxenye yesistimu ethembekile yokuvala shaft.
Udebe oluvalayo endaweni ye-flange lunikeza uphawu oluhle, futhi ukwakheka okwenziwe kahle kolwelwesi kuqinisekisa ukubamba okunembile emzimbeni. I-square drive disc ihlinzeka ngokudluliswa kwe-torque okusebenzayo futhi okuqinile, futhi unqenqema lwediski yokupholisha lunciphisa ukungqubuzana.
Uchungechunge lwe-Desponia luqinisekisa ukusebenza okuphephile ezinqubweni zokuhlanza amanzi, ukukhiqizwa kwamandla kanye nezicelo zokwelashwa zamakhemikhali ezidinga kakhulu. Lawa mavalvu angakwazi futhi ukumelana nokusebenza embonini yensimbi, lapho amavalvu okuvala asetshenziselwa ukufutha insimbi encibilikisiwe echayeka ezimeni ezinzima. Lawa ma-valve anama-discs aboshwe ngokukhethekile nawo afanelekela izimayini nodaka, futhi asetshenziswa ezinqubweni zokukhipha ezidinga ama-valve anokumelana okuphezulu kakhulu nokumelana nokugqwala.
