Uyini Umehluko Phakathi Kwama-Flanged Butterfly Valve Nama-Lugged Butterfly Valve

Uma kukhulunywa ngokuthiamavalvu ebhabhathane, esinye sezinqumo zokuqala abathengi ababhekene nazo ukukhetha phakathi kwe-ivalvu yebhabhathane elijiyilekanyeivalvu yebhabhathane elithwele. Uma uqala ukubheka, zibukeka zifana. Zombili zenzelwe ukulawulwa kokugeleza kwamapayipi, zombili zincane, futhi zombili zisetshenziswa kabanzi ezinhlelweni zokuhlanza amanzi zasolwandle, ze-HVAC, zikawoyela negesi, kanye nezinhlelo zokuhlanza amanzi. Kodwa indlela ezixhuma ngayo kumapayipi—nendlela ezisetshenziswa ngayo—izenza zihluke.

Amavalvu e-Flanged Butterfly Ukuxhumeka Okugcwele kanye Nokulungiswa Okulula

Ivalvu yebhabhathane egobile inama-flange ezinhlangothini zombili zomzimba. La ma-flange anamathela ngqo phakathi kwama-flange amabili epayipi, okwenza uxhumano oluphephile nolugcwele ubuso. Ngenxa yalolu hlobo, ahlinzeka:

• Ukusebenza okuqinile kokuvala: Kuphelele ekusetshenzisweni kokucindezela okuphezulu.

• Ukufakwa okulula: Ivalvu ingena kahle phakathi kwama-flange amabili afanayo.

• Ukugcinwa okuphephile: Ungasusa ivalvu ngaphandle kokuphazamisa lonke ipayipi.

Amavalvu ebhabhathane anombala ogqamile avame ukusetshenziswa emipayipini emikhulu nasezinhlelweni ezisingatha umfutho ophezulu noma ezidinga ukulungiswa njalo. Ezinhlelweni zasolwandle, isibonelo, avame kakhulu emigqeni yamanzi okupholisa injini noma ezinhlelweni ze-ballast lapho ukuphepha nokuthembeka kuza kuqala.

Amavalvu Ebhabhathane Agcwele: Aguquguqukayo Futhi Asindisa Isikhala

Ivalvu yebhabhathane elayishiwe inezifakelo ezinezintambo (noma “izinqe”) ezizungeze umzimba. Lawa ma-lug avumela ivalvu ukuthi iboshwe ngqo kuma-flange epayipi ezinhlangothini zombili. Inzuzo eyinhloko? Ungasusa uhlangothi olulodwa lwepayipi ngenkathi olunye uhlangothi lusebenza.

• Ukuguquguquka: Zingasetshenziswa kokubili ekusetshenzisweni okungapheli kanye nasekugelezeni okuqondile.

• Umklamo omncane: Ilungele amapayipi lapho isikhala silinganiselwe khona.

• Ukusebenza kahle kwezindleko: Ngokuvamile kulula futhi konga imali kunezivalo ezifakwe ngokuphelele.

Amavalvu agcwele avame ukukhethwa kumapayipi amancane noma izinhlelo lapho ukuqina nokuguquguquka kubaluleke kakhulu kunamandla aphezulu. Emapayipini emikhumbi, awusizo ezinhlelweni ezisizayo noma emigqeni yamanzi yesibili lapho isikhala sincane khona.

Umehluko Oyinhloko Ngokushesha

• Ukuxhumeka: Ama-valve ahlanganisiwe ahlanganisa ama-flange amabili amapayipi, kuyilapho ama-valve ahlanganisiwe esebenzisa ama-insert anezintambo ukuze anamathiselwe ngqo.

• Amandla: Amavalvu afakwe i-flanged aphatha ukucindezeleka okuphezulu futhi aphephile kakhulu ekusetshenzisweni okubalulekile.

• Ukuguquguquka: Amavalvu anamathele avumela uhlangothi olulodwa lwepayipi ukuthi lunqanyulwe ngaphandle kokuvala lonke uhlelo.

• Izicelo: Ifakwe i-flanged yezinhlelo ezisindayo, ezinomfutho ophezulu, nezibucayi. Ifakwe i-lug yezinhlelo ezincane, eziguquguqukayo, noma zesibili.

Yikuphi Okufanele Ukhethe

• Khetha ivalvu yebhabhathane egobile uma udinga ukuqina, ukuvala okuqinile, kanye nekhono lokucindezela okuphezulu.

• Khetha ivalvu yovemvane ethwele uma isikhala, isisindo, kanye nokuhlukaniswa okulula kubaluleke kakhulu.

Zombili lezi zakhiwo zidlala indima ebalulekile ezinhlelweni zasolwandle nezezimboni. Ukubambisana nomuntu othembekileumenzi wamavalvu olwandleiqinisekisa ukuthi uthola ama-valve enziwe ngezinto ezifanele, ahlolwe ukuthembeka, futhi aqinisekiswe amazinga omhlaba wonke.
