Isisindo sika auvemvane valvekubalulekile ekwakhiweni okuphelele kwesistimu. Kuthinta ukufakwa, ukugcinwa, kanye nokusebenza kahle kohlelo lonke. Eyaziwa ngokuklama kwayo okuhlangene kanye nokulawula ukugeleza okuphumelelayo, ama-butterfly valves abalulekile ekusetshenzisweni okuhlukahlukene kusukela ekuhlanzeni amanzi kuya kuwoyela negesi.
1. Uhlolojikelele Wesisindo Butterfly Valve.
Isisindo sevalve uvemvane sisekelwe enanini lazo zonke izisindo. Isisindo se-valve uvemvane siyahlukahluka kuye ngesakhiwo nokucushwa kwe-valve uvemvane.
1.1 Isakhiwo Esiyisisekelo
A uvemvane valveiqukethe umzimba we-valve, i-disc, isiqu, isihlalo, ne-actuator. Umzimba we-valve ungumzimba oyinhloko, obhekene nokuxhuma i-flange yepayipi, ukwakha i-loop evaliwe, kanye nezindlu nezinye izingxenye. I-disc izungeza i-axis ephakathi, futhi lokhu kujikeleza kuvumela i-valve ukuthi ivule noma ivale, ngaleyo ndlela ilawule ukugeleza kwamanzi noma amagesi. I-valve stem ixhuma i-disc ku-actuator, engasebenza ngesandla noma ngokuzenzakalelayo. Isihlalo siqinisekisa ukuvala okuqinile ukuvimbela ukuvuza.
Ukubaluleka kwe-Valve Weight
- Ukucabanga ngemicabango
Isisindo se-valve sidlala indima ebalulekile ekwakhiweni kwesistimu. Amandla okuthwala wesakhiwo esisekelayo kufanele acatshangelwe ngesikhathi sokuklama. Ama-valve asindayo angadinga ukwesekwa okwengeziwe, okwandisa inkimbinkimbi yokufaka.
-Ukufakwa Nokugcinwa
Ama-valve alula ngokuvamile enza ukufakwa kalula futhi anciphise izindleko zabasebenzi. Zidinga ukuphathwa nokusekelwa okuncane, okwenza ukunakekelwa kufinyeleleke kakhudlwana futhi kusebenziseke. Lokhu lula kokulungiswa kunganciphisa isikhathi sokuphumula kanye nezindleko eziphansi zokusebenza.
-Efficiency Impact
Ama-valve alula anganikeza izikhathi zokuphendula ngokushesha. Izinketho zokuklama kwesakhiwo zingathuthukisa ukusebenza, ziqinisekise ukuthi i-valve ihlangabezana nezidingo ezithile zokusebenza. Isibonelo, amavalvu ovemvane alula kakhulu kunamavalvu esango endabuko, ngakho-ke amavalvu ovemvane angathuthukisa ukusebenza kahle kwezinhlelo zokulawula uketshezi.
-Izindleko Ukucatshangelwa
Isisindo se-valve sithinta izindleko zayo ngezindlela eziningi. Amavalvu asindayo angase abe nezindleko eziphakeme zokuthumela nezokuphatha. Ukwengeza, izinto ezisetshenziswa ekukhiqizeni zingathinta intengo iyonke. Ukukhetha isisindo se-valve esifanele kungasindisa izindleko ezibalulekile, kokubili ngokuthenga kokuqala nokugcinwa kwesikhathi eside.

Ukuhlukaniswa ngohlobo
Uhlobo lwe-valve uvemvane luthinta isisindo salo nokufaneleka kwesicelo. Ithebula lesisindo se-valve uvemvane lihlukanisa i-valve ngezinhlobo ezintathu eziyinhloko, ngayinye enezici ezihlukene kanye nokusetshenziswa.
Uhlobo lwe-Wafer
Ama-valve evemvane eyi-wafer ahlangana ngokuqinile phakathi kwama-flange futhi adinga amabhawodi amane kuphela, athatha isikhala esincane. Lo mklamo unciphisa isisindo, okwenza ama-valve angama-wafer alungele izinhlelo zokusebenza lapho imikhawulo yesikhala nesisindo ibalulekile.
Uhlobo lwe-Lug
Ama-valve evemvane e-Lug afaka okufakwayo okunentambo okungafakwa kusetshenziswa amabhawudi, ngaphandle kwamantongomane. Lo mklamo unikeza ukuzinza okwengeziwe kanye nokulula kokugcinwa, ikakhulukazi ezinhlelweni ezidinga ukuqaqa njalo. Isisindo se-lug butterfly valves sincike ezintweni ezifana nokwakheka kwezinto ezibonakalayo nosayizi, ezithinta izindleko nokusebenza kwazo.
Uhlobo Lwe-Flanged
Ama-valve ovemvane ane-Flanged ahlinzeka ngoxhumano oluphephile noluvikelekile ezinhlelweni zamapayipi. Umklamo wabo uhlanganisa ama-flange aboshwe ngokuqondile epayipi, okuthuthukisa ukuzinza nokumelana nokuvuza. Nakuba ama-valve ane-flanged evame ukuba nzima, ukuqina kwawo namandla kuwenza afanelekele ukusetshenziswa kokucindezela okuphezulu.
Isifinyezo
Ukuqonda isisindo samavalvu ovemvane kubalulekile ekwandiseni ukwakheka nokusebenza kwesistimu. Isisindo se-valve singathinta ukufakwa, ukugcinwa, kanye nokusebenza kahle kukonke. Ngokucabangela isisindo se-valve, onjiniyela bangenza izinqumo ezinolwazi ezilinganisa ukusebenza, ukuqina, kanye nezindleko. Lokhu kuqinisekisa ukuthi i-valve ekhethiwe ihlangabezana nezidingo ezithile zohlelo lokusebenza.
"Ukukhetha ama-valve okulungile kuhilela ukuhlola izidingo zohlelo lokusebenza ngokombono wosayizi we-valve, ukwakheka kwesistimu, izakhiwo zezinto ezibonakalayo, izidingo zokufakwa nokugcinwa, izindleko kanye nokuhambisana nomthetho."
