Yintoni umahluko phakathi kweevalvu zebhabhathane ezine-Flanged kunye ne-Lugged Butterfly Valves

Xa kufikwa kuiivalvu zebhabhathane, esinye sezigqibo zokuqala abathengi abajongene nazo kukukhetha phakathiivalvu yebhabhathane ejijekileyokunyeivalvu yebhabhathane ethwele. Xa uzijonga okokuqala, zifana. Zombini zenzelwe ukulawula ukuhamba kwamanzi kwiipayipi, zombini zincinci, kwaye zombini zisetyenziswa kakhulu kwiinkqubo zonyango lwamanzi, i-HVAC, ioyile negesi, kunye neenkqubo zokunyanga amanzi. Kodwa indlela eziqhagamshela ngayo kwiipayipi—nendlela ezisetyenziswa ngayo—iyazahlula.

Iivalvu zebhabhathane ezijijekileyo Uqhagamshelo olupheleleyo kunye nokugcinwa okulula

Ivalvu yebhabhathane ejijekileyo ineeflange kumacala omabini omzimba. Ezi flanges zibopha ngqo phakathi kweeflanges ezimbini zepayipi, zenze uqhagamshelo olukhuselekileyo nolupheleleyo. Ngenxa yolu yilo, zibonelela:

• Ukusebenza okuqinileyo kokutywina: Ifanelekile kwizicelo zoxinzelelo oluphezulu.

• Ukufakela okulula: Ivalvu ingena kakuhle phakathi kweeflange ezimbini ezifanayo.

• Ulondolozo olukhuselekileyo: Ungayisusa ivalvu ngaphandle kokuphazamisa yonke imibhobho.

Iivalvu zebhabhathane ezine-Flanged zidla ngokusetyenziswa kwiipayipi ezinkulu nakwiinkqubo ezisingatha uxinzelelo oluphezulu okanye ezifuna ukulungiswa rhoqo. Kwiinkqubo zaselwandle, umzekelo, zixhaphakile kwiindlela zamanzi ezipholileyo zenjini okanye kwiinkqubo ze-ballast apho ukhuseleko nokuthembeka kuza kuqala.

Iivalvu zebhabhathane ezixhonyiweyo: Eziguquguqukayo nezigcina isithuba

Ivalvu yebhabhathane ethwele imitya inee-inserts ezinemisonto (okanye "ii-lugs") ezijikeleze umzimba. Ezi lugs zivumela ivalvu ukuba ibotshelelwe ngqo kwiiflanges zepayipi kumacala omabini. Inzuzo ephambili? Ungasusa icala elinye lepayipi ngelixa elinye icala lisebenza.

• Ukuguquguquka: Zingasetyenziswa kwinkonzo engapheliyo kunye nokuhamba kweendlela ezimbini.

• Uyilo oluncinci: Lulungele imibhobho apho indawo incinci khona.

• Ukusebenza kakuhle kweendleko: Ngokwesiqhelo kulula kwaye kungabizi kakhulu kuneevalvu ezijikelezileyo ngokupheleleyo.

Iivalvu ezixineneyo zihlala zikhethwa kwiipayipi ezincinci okanye iinkqubo apho ubuncinci kunye nokuguquguquka kubaluleke ngaphezu kwamandla aphezulu. Kwimibhobho yenqanawa, ziluncedo kwiinkqubo ezincedisayo okanye kwimigca yamanzi yesibini apho indawo incinci khona.

Umahluko oPhambili ngokuKhawuleza

• Uqhagamshelo: Iivalvu ezijijekileyo zibopha phakathi kweeflange ezimbini zepayipi, ngelixa iivalvu ezijijekileyo zisebenzisa i-inserts ezinemisonto ukuze zincamathise ngqo.

• Amandla: Iivalvu ezijijekileyo zikwazi ukumelana noxinzelelo oluphezulu kwaye zikhuselekileyo kwiindlela ezibalulekileyo zokusetyenziswa.

• Ukuguquguquka: Iivalvu ezixhonyiweyo zivumela icala elinye lombhobho ukuba liqhawulwe ngaphandle kokuvala yonke inkqubo.

• Ukusetyenziswa: Ifakwe kwi-flanged ukuze isetyenziselwe iinkqubo ezinzima, ezinoxinzelelo oluphezulu, nezibalulekileyo. Ifakwe kwi-fixed systems ezincinci, eziguquguqukayo, okanye ezingephi.

Yeyiphi Ofanele Uyikhethe

• Khetha ivalvu yebhabhathane ejijekileyo ukuba ufuna ukuqina, ukutywinwa okuqinileyo, kunye nokukwazi ukusebenza ngoxinzelelo oluphezulu.

• Khetha ivalvu yebhabhathane ethwele umthwalo ukuba indawo, ubunzima, kunye nokulula ukuyihlukanisa kubaluleke kakhulu.

Zombini ezi zakhiwo zidlala indima ebalulekileyo kwiinkqubo zaselwandle nakwimizi-mveliso. Ukusebenzisana nomntu othembekileyoumenzi weevalvu zaselwandleiqinisekisa ukuba ufumana iivalvu ezenziwe ngezinto ezifanelekileyo, zivavanyelwe ukuthembeka, kwaye ziqinisekiswe ukuba zisemgangathweni wehlabathi.
