I-Butterfly Valve luhlobo lwesixhobo sokulawula ukuhamba kwamanzi esinentshukumo yokujikeleza kwekota, Isetyenziswa kwimibhobho ukulawula okanye ukwahlukanisa ukuhamba kwamanzi (ulwelo okanye iigesi), Nangona kunjalo, i-butterfly valve esemgangathweni nesebenzayo kufuneka ifakelwe isitywino esilungileyo. Ngaba ii-butterfly valves zibhekisa kwicala elinye? Ngokwesiqhelo sahlula i-butterfly valves zibe zii-Concentric butterfly valves kunye ne-eccentric butterfly valve.
Siza kuthetha ngevalvu yebhabhathane ejikelezayo ejikelezileyo njengoko kuboniswe ngezantsi:
Yintoni ivalvu yebhabhathane e-Concentric?
Ivalvu yebhabhathane engqindilili yaziwa njengevalvu yebhabhathane ehleli phantsi okanye engangenisi mandla, iinxalenye zayo ziquka: Umzimba wevalvu, idiski, isihlalo, isiqu kunye nesitywina. Ulwakhiwo lwevalvu yebhabhathane engqindilili yidiski kwaye isihlalo silungelelaniswe embindini wevalvu, kwaye umngxuma okanye isiqu sikwimbindi wediski. Oku kuthetha ukuba idiski ijikeleza ngaphakathi kwesihlalo esithambileyo, Izinto zesihlalo zingabandakanya i-EPDM, i-NBR Viton Silicon Teflon Hypalon okanye i-elastomer.
Uyisebenzisa njani ivalvu yebhabhathane egxile kwi-concentric?
Ukwakhiwa kwevalvu yebhabhathane kulula kakhulu, kukho iindlela ezintathu ze-actuator yokusebenza: I-Lever Handle yobukhulu obuncinci, Ibhokisi yeGiya yeWorm yeevalvu ezinkulu ukuze kube lula ukulawula kunye nokusebenza ngokuzenzekelayo (kubandakanya ii-Actuators zoMbane kunye ne-Pneumatic)
Ivalvu yebhabhathane isebenza ngokujikeleza idiski (okanye ivane) ngaphakathi kombhobho ukulawula ukuhamba kolwelo. Idiski ifakwe kwisiqu esidlula emzimbeni wevalvu, kwaye ukuguqula isiqu kujikelezisa idiski nokuba kuyivula okanye kuyivala ivalvu. Njengoko ishaft ijikeleza, idiski ivula kwindawo evulekileyo okanye evulekileyo kancinci, ivumela ulwelo ukuba luhambe ngokukhululekileyo. Kwimeko evaliweyo, iShaft ijikelezisa idiski ukuvimba ukuhamba kwayo ngokupheleleyo kwaye iyivale ivalvu.
Ngaba iivalvu zebhabhathane zibhekisa kwicala elinye?
Iindlela ezibhekisa kwicala elinye zinokulawula ukuhamba kumacala omabini, njengoko besitshilo, umgaqo wokusebenza kweevalvu unokufikelela kwiimfuno. Ngoko ke iivalvu zebhabhathane ezijolise kwicala elinye zibhekisa kwicala elinye, Zininzi iingenelo zokusebenzisa ivalvu yebhabhathane ejolise kwicala elinye.
1 Ingabizi kakhulu kunezinye iintlobo zeevalvu ngenxa yoyilo lwazo olulula kunye nezixhobo ezimbalwa ezifunekayo ekwakheni. Ukonga iindleko kwenziwa ikakhulu ngobukhulu beevalvu ezinkulu.
2 Kulula ukuyisebenzisa, ukuyifaka kunye nokulungisa, i-concenric butterfly valve elula yenza kube lula kwaye kukhawuleze ukuyifaka, inokunciphisa iindleko zomsebenzi, uyilo olulula, olunoqoqosho oluneendawo ezimbalwa ezihambayo, kwaye ngenxa yoko iindawo zokuguguleka zincinci, zinciphisa kakhulu iimfuno zazo zokugcina.
3 Uyilo olukhaphukhaphu noluncinci kunye nobukhulu obuncinci bobuso nobuso bevalvu yebhabhathane edibeneyo, Iyakwazi ukufakwa nokusetyenziswa kwiindawo ezinqongopheleyo, Ifuna indawo encinci xa ithelekiswa nezinye iintlobo zeevalvu, ezifana neevalvu zesango okanye zeglobhu, kwaye ukuqina kwazo kwenza kube lula ukufakwa nokusebenza, ngakumbi kwiinkqubo ezixineneyo.
4 Ukusebenza ngokukhawuleza, uyilo lokujikeleza olune-engile yasekunene (iidigri ezingama-90) lubonelela ngokuvula nokuvala ngokukhawuleza. Olu phawu lubalulekile kwizicelo apho impendulo ekhawulezayo ibalulekile, njengakwiinkqubo zokuvala ezingxamisekileyo okanye iinkqubo ezineemfuno zolawulo oluchanekileyo. Ukukwazi ukuvula nokuvala ngokukhawuleza kuphucula ukusabela kwenkqubo, okwenza iivalvu zebhabhathane ezixineneyo zifaneleke ngokukodwa kulawulo lokuhamba kunye nolawulo lokuvula/lokuvala kwiinkqubo ezifuna ixesha eliphezulu lokuphendula.
Okokugqibela, ivalvu yebhabhathane emacala mabini eneempawu zokutywina kwicala ngalinye ibangelwa yisakhiwo sayo sokutywina esithambileyo phakathi kwesihlalo sevalvu kunye nediski yebhabhathane, iqinisekisa ukutywina rhoqo nokuba ulwelo luhamba ngaliphi na icala. Olu yilo luphucula ngokufanelekileyo ukuthembeka kwevalvu kwinkqubo yolawulo lolwelo olumacala mabini.
