Zimene Muyenera Kudziwa Zokhudza Ma Valves a Gulugufe a AWWA

Ponena za zomangamanga za ntchito zamadzi, kukonza madzi otayira, ndi mapaipi a boma, mitundu yochepa ya ma valve ndi yodalirika komanso yogwiritsidwa ntchito kwambiri mongaValavu ya gulugufe ya AWWAMa valve amenewa amadziwika kuti ndi otchipa, osavuta kugwiritsa ntchito, komanso okhala ndi nthawi yayitali yogwira ntchito, ndipo amathandiza kwambiri pakulamulira kayendedwe ka madzi m'madzi akuluakulu. Koma n’chiyani chimawasiyanitsa, ndipo mumasankha bwanji yoyenera kugwiritsa ntchito?

Munkhaniyi, tikambirana zonse zomwe muyenera kudziwa zokhudzaMa valve a gulugufe a AWWA—kuyambira miyezo ndi kapangidwe mpaka kugwiritsa ntchito ndi malangizo ofunikira posankha.

1. Kodi Valavu ya Gulugufe ya AWWA ndi Chiyani?

An Valavu ya gulugufe ya AWWAndi mtundu wa valavu yozungulira kotala yomwe imapangidwira kulamulira kapena kulekanitsa kuyenda kwa madzi, makamaka m'malo osungira madzi ndi m'malo otayira madzi. Mawu ofupikitsa akuti "AWWA" amatanthauzaBungwe la American Water Works Association, yomwe imakhazikitsa miyezo ya kapangidwe, kupanga, ndi magwiridwe antchito a ma valve omwe amagwiritsidwa ntchito m'maboma ndi m'mafakitale.

Mafotokozedwe odziwika bwino a ma valve awa ndiAWWA C504, yomwe imafotokoza zofunikira pa ma valve a gulugufe okhala ndi rabara kuyambira mainchesi 75 mpaka mainchesi 1800 (1800mm) m'mimba mwake.

2. Zinthu Zofunika Kwambiri za Ma Valves a Gulugufe a AWWA

1. Ntchito Yotembenuza Kotala
   Disikiyo imazungulira madigiri 90 kuti itsegule kapena kutseka njira yoyendera, zomwe zimathandiza kuti ntchito iyende mwachangu komanso kuti mphamvu ya mpweya isachepe.

2. Wokhazikika Wokhala
   Ma valve amenewa amagwiritsa ntchito mipando ya rabara kapena elastomeric kuti atsimikizire kuti imatsekedwa bwino komanso kuti isatuluke, ngakhale atagwiritsidwa ntchito kwa nthawi yayitali.

3. Kukana Kudzikundikira
   Zophimba zamkati ndi zakunja (nthawi zambiri epoxy) zimateteza thupi la valavu ndi diski ku dzimbiri m'malo ovuta amadzi.

4. Kapangidwe Kakang'ono
   Poyerekeza ndi ma valve a pachipata, ma valve a gulugufe a AWWA ndi opepuka ndipo satenga malo ambiri, zomwe ndi zabwino kwambiri poyika zinthu zolimba.

5. Moyo Wautali wa Utumiki
   Ndi kukonza bwino, ma valve amenewa amatha kugwira ntchito kwa zaka zambiri, makamaka m'madzi oyera.

3.AWWA C504 VS AWWA C516

PameneAWWA C504imaphimba ma valve agulugufe okhala ndi rabara, atsopanoAWWA C516maadiresima valve a gulugufe ogwira ntchito kwambiri (HPBVs), zomwe zimayenera kugwiritsidwa ntchito molimbika kwambiri komanso molimbika kwambiri.

4. Momwe Mungasankhire Valavu Yabwino ya AWWA Butterfly

1. Kukula kwa Chitoliro ndi Kuyeza kwa Kupanikizika
   Yerekezerani kukula kwa valavu ndi kalasi yake ndi zofunikira za makinawo. Mavalavu a AWWA amapezeka m'magulu osiyanasiyana opanikizika (monga 150A, 150B).

2. Mautumiki Othandizira
   Tsimikizirani kuti ikugwirizana ndi madzi, madzi otayira, kapena madzi ena.

3. Mikhalidwe Yogwirira Ntchito
   Yesani kutentha, kuthamanga kwa mpweya, komanso ngati pakufunika kupopera kapena kudzipatula.

4. Malumikizano Otsiriza
   Ma valve a gulugufe a AWWA amapezeka ndi malekezero olumikizana opindika, opindika, kapena opangidwa ndi makina.

5. Njira Yogwiritsira Ntchito
   Sankhani pakati pa kugwiritsa ntchito zida zamanja, ma actuator amagetsi, makina opopa madzi kapena ma hydraulic kutengera zosowa za makina odzipangira okha.

6. Ziphaso
   Onetsetsani kuti valavu ikutsatira miyezo ya AWWA, ndipo ngati ikugwiritsidwa ntchito m'makina oyeretsera madzi, iyenera kukhala ndi satifiketi ya NSF 61.
