Okudingeka Ukwazi Ngama-AWWA Butterfly Valve

Uma kukhulunywa ngengqalasizinda yemisebenzi yamanzi, ukwelashwa kwamanzi amdaka, kanye nezinhlelo zamapayipi kamasipala, zimbalwa izinhlobo zamavalvu ezithembekile futhi ezisetshenziswa kabanzi njengeI-valve yebhabhathane le-AWWA. Njengoba zaziwa ngokusebenza kahle kwezindleko, ukulula kokusebenza, kanye nokuphila isikhathi eside, la ma-valve adlala indima ebalulekile ekulawuleni ukugeleza kwamanzi ezinhlelweni zamanzi ezinobubanzi obukhulu. Kodwa yini ewenza avelele, futhi ukhetha kanjani elifanele isicelo sakho?

Kulesi sihloko, sizoxoxa ngakho konke okudingeka ukwazi ngakhoAmavalvu ebhabhathane e-AWWA—kusukela ezindinganisweni nasekwakheni kuya ekusetshenzisweni kanye namathiphu okukhetha abalulekile.

1. Iyini i-AWWA Butterfly Valve

An I-valve yebhabhathane le-AWWAuhlobo lwevalvu yokujika ngekota eyenzelwe ukulawula noma ukuhlukanisa ukugeleza koketshezi, ikakhulukazi emisebenzini yamanzi nasezinhlelweni zamanzi angcolile. Isifinyezo esithi “AWWA” simelelaInhlangano Yemisebenzi Yamanzi yaseMelika, ebeka izindinganiso zokuklama, ukukhiqiza, kanye nokusebenza kwamavalvu asetshenziswa ezinhlelweni zamanzi zikamasipala nezezimboni.

Incazelo evame kakhulu yalezi valve yileI-AWWA C504, echaza izidingo zamavalvu ebhabhathane ahlala enjoloba kusukela ku-3 inches (75mm) kuya ku-72 inches (1800mm) ububanzi.

2. Izici Eziyinhloko Zama-AWWA Butterfly Valve

1. Ukusebenza Kokujika Kwekota
   Idiski ijikeleza ama-degree angu-90 ukuze ivule noma ivale ngokuphelele indlela yokugeleza, okwenza kube lula ukusebenza ngokushesha kanye nokulahlekelwa okuncane kwengcindezi.

2. Ihlezi Ngokuqinile
   Lawa ma-valve asebenzisa izihlalo zerabha noma ze-elastomeric ukuqinisekisa ukuvalwa okuqinile nokuvimbela ukuvuza, ngisho nangemva kokusetshenziswa isikhathi eside.

3. Ukumelana Nokugqwala
   Izimbozo zangaphakathi nezangaphandle (ngokuvamile i-epoxy) zivikela umzimba we-valve kanye ne-disc ekugqwaleni ezimweni zamanzi ezinzima.

4. Umklamo Omncane
   Uma kuqhathaniswa nama-valve esango, ama-valve e-butterfly e-AWWA alula futhi athatha isikhala esincane, okuyinto efanele ukufakwa okuqinile.

5. Impilo Ende Yenkonzo
   Uma kunakekelwa kahle, la ma-valve angasebenza amashumi eminyaka, ikakhulukazi lapho kusetshenziswa amanzi ahlanzekile.

3.AWWA C504 VS AWWA C516

NgesikhathiI-AWWA C504ihlanganisa amavalvu ebhabhathane ajwayelekile ahlala enjoloba, okushaI-AWWA C516amakheliamavalvu ebhabhathane asebenza kahle kakhulu (ama-HPBV), ezifanele ukusetshenziswa kokucindezela okuphezulu kanye nezicelo ezidinga kakhulu.

4.Ungayikhetha Kanjani I-AWWA Butterfly Valve Efanele

1. Usayizi Wepayipi kanye Nesilinganiso Sokucindezela
   Qondanisa usayizi wevalvu kanye neklasi nezidingo zesistimu. Amavalvu e-AWWA atholakala ngezigaba eziningi zokucindezela (isb., 150A, 150B).

2. Imidiya Yesevisi
   Qinisekisa ukuthi iyahambisana namanzi, amanzi angcolile, noma olunye uketshezi.

3. Izimo Zokusebenza
   Hlola amazinga okushisa, ingcindezi, nokuthi ngabe kudingeka yini ukugoqa noma ukuhlukaniswa.

4. Ukuphela Kokuxhumana
   Amavalvu e-butterfly e-AWWA ayatholakala aneziphetho ezihlanganisiwe, ezinemiphetho, noma ezihlanganisiwe.

5. Indlela Yokusebenza
   Khetha phakathi kokusebenza kwegiya ngesandla, ama-actuator kagesi, izinhlelo zomoya noma ze-hydraulic ngokusekelwe ezidingweni zokuzenzakalela kwesistimu.

6. Izitifiketi
   Qinisekisa ukuthi ivalvu ihambisana nezindinganiso ze-AWWA, futhi uma isetshenziswa ezinhlelweni zamanzi aphuzwayo, kufanele iqinisekiswe yi-NSF 61.
