Oko Ufanele Ukukwazi Ngee-AWWA Butterfly Valves

Xa kufikwa kwiziseko zophuhliso lwemisebenzi yamanzi, unyango lwamanzi amdaka, kunye neenkqubo zemibhobho kamasipala, zimbalwa iintlobo zeevalvu ezithembekileyo nezisetyenziswa kakhulu njengeIvalvu yebhabhathane ye-AWWA. Ezaziwa ngokusebenza kakuhle kweendleko, ukulula kokusebenza, kunye nobomi benkonzo ende, ezi valve zidlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi kwiinkqubo zamanzi ezinkulu. Kodwa yintoni ezenza zibonakale, kwaye ukhetha njani efanelekileyo kwisicelo sakho?

Kweli nqaku, siza kugubungela yonke into ekufuneka uyazi malungaIivalvu zebhabhathane ze-AWWA—ukususela kwimigangatho kunye nolwakhiwo ukuya kwizicelo kunye neengcebiso ezibalulekileyo zokukhetha.

1. Yintoni iValve yeButterfly ye-AWWA

An Ivalvu yebhabhathane ye-AWWAluhlobo lwevalvu yokujika ikota eyenzelwe ukulawula okanye ukwahlula ukuhamba kolwelo, ingakumbi kwimisebenzi yamanzi nakwiinkqubo zamanzi amdaka. Isifinyezo esithi “AWWA” simeleUmbutho waseMelika weMisebenzi yamanzi, ebeka imigangatho yoyilo, ukwenziwa, kunye nokusebenza kweevalvu ezisetyenziswa kwiinkqubo zamanzi zikamasipala nezemizi-mveliso.

Eyona nkcazelo ixhaphakileyo kwezi valves yileAWWA C504, echaza iimfuno zeevalvu zebhabhathane ezihlala ngerabha ukusuka kwi-3 intshi (75mm) ukuya kwi-72 intshi (1800mm) ububanzi.

2. Iimpawu eziphambili ze-AWWA Butterfly Valves

1. Umsebenzi wokutshintsha ikota
   Idiski ijikeleza iidigri ezingama-90 ukuvula okanye ukuvala indlela yokuhamba, nto leyo evumela ukusebenza ngokukhawuleza kunye nokulahlekelwa kancinci koxinzelelo.

2. Ihleli Eqinileyo
   Ezi valve zisebenzisa izihlalo zerabha okanye ze-elastomeric ukuqinisekisa ukuvalwa okuqinileyo nokuthintela ukuvuza, nokuba sele zisetyenziswe ixesha elide.

3. Ukumelana nokugqwala
   Iingubo zangaphakathi nezangaphandle (ezidla ngokuba yi-epoxy) zikhusela umzimba wevalvu kunye nediski ekungcoleni xa amanzi ebanda.

4. Uyilo oluNcinci
   Xa kuthelekiswa neevalvu zesango, iivalvu zebhabhathane ze-AWWA zikhaphukhaphu kwaye zithatha indawo encinci, nto leyo efanelekileyo xa kufakelwa izinto eziqinileyo.

5. Ubomi beNkonzo ende
   Ukuba zigcinwa kakuhle, ezi valve zingasebenza amashumi eminyaka, ingakumbi xa kusetyenziswa amanzi acocekileyo.

3.AWWA C504 VS AWWA C516

NgelixaAWWA C504igubungela iivalvu zebhabhathane ezisemgangathweni ezihlala ngerabha, entshaAWWA C516iidilesiiivalvu zebhabhathane ezisebenza kakuhle (ii-HPBV), ezifanelekileyo kwiimfuno zoxinzelelo oluphezulu kunye nezicelo ezifuna amandla amaninzi.

4.Ungayikhetha njani iValve yeButterfly ye-AWWA efanelekileyo

1. Ubungakanani bePipe kunye neXinzelelo loXinzelelo
   Tshatisa ubungakanani bevalvu kunye neklasi neemfuno zenkqubo. Iivalvu ze-AWWA ziyafumaneka kwiindidi ezininzi zoxinzelelo (umz., 150A, 150B).

2. Iinkonzo zeMidiya
   Qinisekisa ukuba iyahambelana namanzi, amanzi amdaka, okanye ezinye izinto ezilulwelo.

3. Iimeko Zokusebenza
   Hlola ubushushu, uxinzelelo, kunye nokuba ngaba kuyimfuneko ukuqhobosha okanye ukuhlukanisa.

4. Ukuphelisa uQhagamshelo
   Iivalvu zebhabhathane ze-AWWA ziyafumaneka ezineziphelo ezijijekileyo, ezinemiqolo, okanye ezijijekileyo.

5. Indlela Yokusebenza
   Khetha phakathi kokusebenza kwegiya ngesandla, ii-actuators zombane, iinkqubo ze-pneumatic okanye ze-hydraulic ngokusekelwe kwiimfuno ze-system automation.

6. Iziqinisekiso
   Qinisekisa ukuba ivalvu iyahambelana nemigangatho ye-AWWA, kwaye ukuba isetyenziswa kwiinkqubo zamanzi okusela, kufuneka iqinisekiswe yi-NSF 61.
