3 Uma uzikhethela
3.1 Uhlobo
I-valve uvemvane inezakhiwo ezihlukene ezifana ne-eccentric eyodwa, uhlobo lwepuleti ethambekele, uhlobo lomugqa ophakathi nendawo, i-double eccentric kanye ne-triple eccentric.Ingcindezi emaphakathi isebenza ku-valve shaft futhi ithwala ipuleti levemvane.Ngakho-ke, lapho ukumelana nokugeleza kokucindezela okukhulu kanye nobubanzi obuncane kukhulu, ububanzi be-shaft kanye nobukhulu bepuleti le-butterfly kuzokwanda ngokufanele.Uma ama-valve esango, ama-valve ebhola noma ama-valve e-globe asetshenziswa, kusukela ezicini zokuvala uphawu nokumelana nokugeleza Ukuhlaziywa kufaneleka kakhulu kune-valve ye-butterfly.

Eminyakeni yamuva nje, ukuvela kwama-valve esango elinesivalo esithambile ezinhlelweni zamanzi kuye kwathuthukisa ukushiyeka kwama-valve amasango alula ukudilika.Ukumelana nokugeleza kwayo kuncane, futhi kungalungiswa ku-inthanethi.Ifaneleka kakhulu kuma-diameters amancane naphakathi, ngakho-ke isetshenziswe kancane kancane.
3.2 Ukuvala uphawu
Izinzuzo eziyinhloko ze-valve ye-butterfly yokuvalwa kwensimbi ukubekwa uphawu okuthembekile, impilo ende, ukumelana nokushisa okuphezulu, akulula ukulimaza nokuklebhula, kanye nomfutho ophezulu wokuthwala umthamo.Ngakho-ke, isetshenziswe kabanzi eminyakeni yamuva, ikakhulukazi ezingxenyeni ezibalulekile zezinhlelo zobunjiniyela.Uma i-valve ye-butterfly evala uphawu ethambile iklanywe kahle futhi yakhiwe, ingavalwa kahle, futhi ububanzi obukhulu bungashintshwa kalula ku-inthanethi.Kodwa-ke, irabha inezinkinga zokuguga futhi ingasetshenziswa kuphela ezimweni zokusebenza lapho izinga lokushisa lingekho phezulu, ngakho-ke isetshenziswa kakhulu emanzini kampompi kanye nezinhlelo zokuhlinzeka ngamanzi.

Ama-valve evemvane ensimbi angaphandle asetshenziswa eziteshini zokumpompa, ama-condensers, amasistimu okukhipha umusi kanye nezinhlelo zokushintshanisa ukushisa ezitshalweni zamandla ashisayo.Izitshalo zamandla enuzi ziphinde zisetshenziswe ekuhlukaniseni amagobolondo okucindezela, amasistimu wokufafaza kanye ne-brine, njll., ukuhlukaniswa kokugcina uwoyela kanye nesitimu ezinhlelweni zokuhluza i-petroleum.I-valve yokuhlinzeka, uhlelo lwe-desulfurization kanye nokwelashwa kwegesi yomsila, ukuqhekeka okushisayo kanye neyunithi ye-catalytic.Kukhona nezitshalo ze-petrochemical, i-cryogenic, i-slurry kanye nezinhlelo zokwenza amaphepha.
Ngokushisa okuphakathi nezimo zokucindezela okuphakathi, kungcono ukusebenzisa ama-valve butterfly okuvalwa kwensimbi.Ezindaweni ezidinga ukwethembeka okuphezulu, impilo ende, kanye nokushintshwa kwesikhathi eside, ama-butterfly valves anezinsimbi kufanele asetshenziswe.
Ukuze i-valve esetshenziselwa amanzi okushisa ajwayelekile, uma ingafuni kakhulu, ngeke ithathelwe indawo isikhathi eside noma lapho kungenakulungiswa khona ukushintshwa, kuhle ukuthatha i-valve ye-butterfly enesakhiwo se-soft seal.Uma izinga lenjoloba lingaqinisekiswa, amavalvu ovemvane anobubanzi obukhulu emanzini kusafanele abe amavalvu esihlalo serabha uvemvane.
4 Isiphetho
Ukuvela okuqhubekayo kobuchwepheshe obusha nezinto ezintsha kuzothuthukisa ukusebenza kwesakhiwo se-valve uvemvane, kwandise ububanzi bokusetshenziswa kwe-valve uvemvane, futhi kubeke phambili izidingo ezibuyekeziwe zokuklama nokukhethwa kwe-valve uvemvane.

I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.
