3 Ongakukhetha
3.1 Uhlobo
Ivalvu yebhabhathane inezakhiwo ezahlukene ezifana nohlobo olulodwa oluyi-eccentric, uhlobo lweplate elithambekele, uhlobo lomugqa ophakathi, oluyi-eccentric kabili noluyi-eccentric kathathu. Ingcindezi ephakathi isebenza emshafini we-valve kanye nokuthwala ngeplate yebhabhathane. Ngakho-ke, lapho ukumelana kokugeleza komfutho ophezulu nobubanzi obuncane kukhulu, ububanzi bomgodi kanye nobukhulu beplate yebhabhathane kuzokhula ngokufanele. Uma kusetshenziswa amavalvu esango, amavalvu ebhola noma amavalvu embulunga, kusukela ezicini zokuvala nokumelana nokugeleza Ukuhlaziywa kufaneleke kakhulu kunevalvu yebhabhathane.

Ingcindezi ephakathi isebenza emshafini we-valve kanye nokuthwala ngeplate yebhabhathane.

Uma kusetshenziswa amavalvu esango, amavalvu ebhola noma amavalvu embulunga, kusukela ezicini zokuvala nokumelana nokugeleza Ukuhlaziywa kufaneleke kakhulu kunevalvu yebhabhathane.
Eminyakeni yamuva nje, ukuvela kwama-valve esango aqinile ezinhlelweni zamanzi kuthuthukise ukushiyeka kwama-valve esango okulula ukuwathulula. Ukumelana nokugeleza kwawo kuncane kakhulu, futhi kungalungiswa ku-inthanethi. Kufanelekile kakhulu kuma-diameter amancane naphakathi, ngakho-ke kuye kwasetshenziswa kancane kancane.
3.2 Ipheya lokuvala
Izinzuzo eziyinhloko zevalvu yebhabhathane yokuvala insimbi ukuvala okuthembekile, ukuphila isikhathi eside, ukumelana nokushisa okuphezulu, akulula ukukonakalisa nokuklebhula, kanye nomthamo wokuthwala umfutho ophezulu. Ngakho-ke, isetshenziswe kabanzi eminyakeni yamuva nje, ikakhulukazi ezingxenyeni ezibalulekile zezinhlelo zobunjiniyela. Uma ivalvu yebhabhathane yokuvala irabha ethambile iklanywe kahle futhi yakhiqizwa kahle, 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 kabanzi emanzini ompompi nasezinhlelweni zokuhlinzeka ngamanzi.

Amavalvu okuvala insimbi yangaphandle asetshenziswa nasezikhungweni zokupompa, kuma-condenser, ezinhlelweni zokukhipha umusi kanye nasezinhlelweni zokushintshanisa ukushisa ezikhungweni zamandla okushisa. Izitshalo zamandla enuzi nazo zisetshenziswa ekuhlukaniseni igobolondo lokucindezela, ezinhlelweni zokufafaza kanye ne-brine, njll., ekuhlukaniseni ukugcina uwoyela kanye nasekwenzeni umusi ezinhlelweni zokuhlanza uphethiloli. Ivalvu yokuphakelwa, uhlelo lokususa i-sulfurization kanye nokwelashwa kwegesi yomsila, ukuqhekeka kokushisa kanye neyunithi yokulungisa. Kukhona nezitshalo ze-petrochemical, izinhlelo ze-cryogenic, ze-slurry kanye nezama-papermaking.
Ezimweni zokushisa okuphakathi kanye nezingcindezi eziphakathi, kungcono ukusebenzisa amavalvu e-butterfly okuvala insimbi. Ezindaweni ezidinga ukuthembeka okuphezulu, ukuphila isikhathi eside, kanye nokushintshwa kwesikhathi eside, kufanele futhi kusetshenziswe amavalvu e-butterfly avaliwe ngensimbi.
Uma ivalvu esetshenziselwa amanzi okushisa ajwayelekile, uma ingafuni kakhulu, ngeke ishintshwe isikhathi eside noma lapho kungalula ukuyishintsha, kungcono ukusebenzisa ivalvu yebhabhathane enesakhiwo esithambile sokuvala. Uma ikhwalithi yerabha ingaqinisekiswa, amavalvu ebhabhathane amakhulu amanzi kufanele abe ngamavalvu ebhabhathane esihlalo serabha.
4 Isiphetho
Ukuvela okuqhubekayo kobuchwepheshe obusha nezinto ezintsha kuzothuthukisa ukusebenza kwesakhiwo sevalvu yevemvane, kwandise ububanzi bokusetshenziswa kwevalvu yevemvane, futhi kubeke phambili izidingo ezibuyekeziwe zokuklama nokukhetha ivalvu yevemvane.

INortech ingenye yabakhiqizi bama-valve ezimboni abahamba phambili eShayina abanesitifiketi sekhwalithi se-ISO9001.
