Uma ukhetha ivalvu efanele yezinhlelo zamapayipi ezimboni, ezolimo, noma ezentengiselwano, ukuqonda umehluko phakathiamavalvu ebhabhathane e-lugfuthiamavalvu ebhabhathane e-flange ephindwe kabilikubalulekile. Womabili ama-valve asetshenziswa kabanzi ekuphathweni kwamanzi, ekucutshungulweni kwamakhemikhali, e-HVAC, nasezimbonini zikawoyela negesi ngenxa yokwakheka kwawo okufushane, ukusebenza kahle kwezindleko, kanye nokulawula ukugeleza okuphumelelayo. Kodwa-ke, ukwakheka kwawo, izindlela zokufaka, kanye nezimo zokusetshenziswa ziyahlukahluka, okwenza ngalinye lifanele izimo ezithile. Lesi sihloko sihlola umehluko oyinhloko, izinzuzo, ukubi, kanye nokusetshenziswa kwama-valve e-lug kanye ne-double flange butterfly ukuqondisa inqubo yakho yokwenza izinqumo.
1. I-Lug Butterfly Valve: Umklamo kanye nezici
Amavalvu e-Lug butterfly abonakala ngokufakwa kwezintambo, noma "ama-lugs," emzimbeni we-valve, okuvumela ukubhoboza okuqondile kuma-flange epayipi. Lo mklamo usebenzisa amasethi amabili amabhobozi azimele ngaphandle kwamantongomane, njengoba amabhobozi ebhoboza ngqo kuma-lugs. Ukucushwa okunjalo kulungele ukusetshenziswa kokuphela komugqa, lapho uhlangothi olulodwa lwepayipi lungaxhunywa ngaphandle kokuthinta olunye.
Izici Eziyinhloko Zama-Lug Butterfly Valve
- Ama-Threaded Lugs: Ama-Lugs ahlinzeka ngezindawo zokufaka eziqinile, okwenza i-valve iboshwe ngokuzimela ku-flange ngayinye yepayipi.
- Umklamo Omncane: Ilula futhi imfushane ngobude, ama-lug valve agcina isikhala, afanele izinhlelo ezinesikhala esincane.
- Ukugeleza Okuqondene Nezinhlangothi Ezimbili: Amavalvu e-lug avaliwe kahle asekela ukugeleza kunoma yiluphi uhlangothi, anikeza ukuguquguquka.
- Ukulungiswa Okulula: Ukucushwa kwe-lug kuvumela uhlangothi olulodwa lwepayipi ukuthi lususwe ukuze lulungiswe ngaphandle kokuthinta olunye.
- Isilinganiso Sokucindezela: Ngokuvamile sifanelekela izinhlelo zokusebenza zokucindezela okuphansi kuya kokuphakathi, yize izilinganiso zokucindezela zingase zehle kwisevisi yokuphela komugqa.
- Ukuguquguquka Kwezinto: Kutholakala ngezinto ezifana ne-ductile iron, i-WCB, noma insimbi engagqwali, kanye nezinketho zezihlalo ezifana ne-EPDM noma i-PTFE yokumelana namakhemikhali.
2. I-Double Flange Butterfly Valve: Umklamo kanye nezici
Amavalvu ebhabhathane ane-flange ehlanganisiwe kuzo zombili izinhlangothi zomzimba we-valve, aboshwe ngqo kuma-flange epayipi afanayo. Lo mklamo uqinisekisa ukuxhumana okungenawo amanzi, okwenza kufaneleke ukusetshenziswa komfutho ophezulu nobubanzi obukhulu. Ukwakhiwa kwawo okuqinile kumelana namandla amakhulu.
Izici Eziyinhloko Zamavalvu E-Double Flange Butterfly
- Ama-Flanges Ahlanganisiwe: Ama-Flanges kuzo zombili izinhlangothi axhuma kuma-flanges amapayipi ngama-bolts, okuqinisekisa ukulingana okuphephile.
- Isakhiwo Esiqinile: Senziwe ngezinto eziqinile njenge-WCB, insimbi ethambile, noma insimbi engagqwali.
- Ukuvalwa Okuphezulu: Ukwakheka kwe-Flange kuqinisekisa ukuvalwa okuqinile, kunciphisa izingozi zokuvuza ezisetshenziswayo ezibalulekile.
- Ukugeleza Okuqondiswayo: Njengama-valve e-lug, ama-valve e-flange aphindwe kabili asekela ukugeleza kuzo zombili izinhlangothi.
- Ububanzi Obukhulu: Ingamela ububanzi obukhulu uma kuqhathaniswa nama-valve e-lug.
3. I-Lug Butterfly Valve vs. I-Double Flange Butterfly Valve
Ukuze wenze ukukhetha okunolwazi, ukuqonda umehluko obalulekile phakathi kwama-valve e-lug nama-flange amabili kubalulekile. Ngezansi ukuqhathanisa okuningiliziwe kwezici ezibalulekile:
3.1 Izici Ezivamile
- Ukuguquguquka Kokufakwa: Kokubili kuvumela uhlangothi olulodwa lwepayipi ukuthi lunqanyulwe ngaphandle kokuthinta olunye, kulungele izinhlelo ezidinga ukulungiswa njalo noma ukuhlukaniswa kwezingxenye.
- Izindleko Uma Ziqhathaniswa Nama-Wafer Valve: Ngenxa yama-lugs anezintambo noma ama-flange amabili, womabili abiza kakhulu kunama-wafer valve.
- Izici Ezihlanganyelwe:
- Ukusekelwa Kokugeleza Okuqondene Nezinhlangothi Ezimbili: Zombili izinhlobo zamavalvu zivumela ukugeleza kunoma yiluphi uhlangothi, zifanele izinhlelo ezineziqondiso zoketshezi eziguquguqukayo.
- Ukuhlukahluka Kwezinto: Zombili zingenziwa ngezinto ezifanayo njengensimbi yekhabhoni, insimbi ethambile, noma insimbi engagqwali, ngezinketho zezihlalo (isb., i-EPDM noma i-PTFE) ezenzelwe uketshezi olufana namanzi, amakhemikhali, noma amagesi.
3.2 Umehluko Oyinhloko
3.2.1 Indlela Yokufaka
- I-Lug Butterfly Valve: Isebenzisa ama-bolts anekhanda elilodwa ukuxhuma kuma-flange epayipi. Ama-lug anezintambo avumela amasethi amabili ama-bolts ukuthi avikele i-valve ngokuzimela ngaphandle kwamantongomane, okusekela isevisi elula yokugcina kanye nokugcinwa kwayo.
- I-Double Flange Butterfly Valve: Inama-flange ahlanganisiwe kuzo zombili izinhlangothi, adinga ukuhambisana nama-flange epayipi kanye ne-bolting. Lokhu kuqinisekisa ukuxhumana okuqinile kodwa kwenza kube nzima ukugcinwa.
3.2.2 Ukuguquguquka Kokufakwa
- I-Lug Butterfly Valve: Inikeza ukuguquguquka okukhulu, njengoba uhlangothi olulodwa lungaxhunywa ngaphandle kokuthinta olunye, lufanele izinhlelo ezidinga ukulungiswa noma ukushintshwa njalo.
- I-Double Flange Butterfly Valve: Idinga ukulungelelaniswa nokuboshwa nhlangothi zombili, okwenza ukufakwa nokususwa kuthathe isikhathi. Inikeza ukuguquguquka okuncane kokulungisa kodwa uxhumano oluphephile.
3.2.3 Ububanzi Obusebenzayo
- I-Lug Butterfly Valve: Ngokuvamile isukela ku-DN50 kuya ku-DN600.Amavalvu e-flange eyodwakungaba yindlela ehlukile yezinhlelo ezincishisiwe isikhala.
- I-Double Flange Butterfly Valve: Isukela ku-DN50 kuya ku-DN1800. Ukuze uthole ububanzi obukhulu, izixazululo ezenziwe ngokwezifiso ziyatholakala uma ziceliwe.
3.2.4 Izindleko Nesisindo
- I-Lug Butterfly Valve: Ingabizi kakhulu ngenxa yokwakheka kwayo okulula, okunciphisa izindleko zokufaka.
- Ivalvu Yebhathabhatha Ene-Flange Ekabili: Inzima futhi ibiza kakhulu ngenxa yama-flange ahlanganisiwe nezinto ezengeziwe. Amavalvu e-flange amabili anobubanzi obukhulu angadinga ukwesekwa okwengeziwe ngenxa yesisindo sawo.
3.2.5 Ukulungiswa Nokuhlukaniswa Kwezakhiwo
- I-Lug Butterfly Valve: Kulula ukuyihlukanisa nokuyinakekela, njengoba uhlangothi olulodwa lungasuswa ngaphandle kokuthinta olunye.
- I-Double Flange Butterfly Valve: Kudinga umsebenzi omningi ukuyihlukanisa ngenxa yama-bolt amaningi kanye nezidingo zokuqondanisa okunembile.

Ukukhetha phakathi kwe-soft-sealedivalvu yebhabhathane le-lugkanyeivalvu yebhabhathane ephindwe kabilikuncike ezidingweni ezithile zesistimu yakho. Amavalvu e-Lug butterfly ahamba phambili ezinhlelweni zokusebenza ezidinga ukulungiswa njalo nokufakwa okuncane. Amavalvu e-double flange butterfly, anokuvalwa kwawo okuqinile, afaneleka kangcono kumapayipi amakhulu kanye nezinhlelo zokusebenza ezibalulekile. Ngokuhlola izici ezifana nokucindezela, ukulungiswa, isikhala, kanye nesabelomali, ungakhetha ivalvu ethuthukisa ukusebenza kanye nokusebenza kahle kwezindleko.
