Chiyambi
Mu dziko la kulamulira madzi, ma valve amachita gawo lofunika kwambiri pakulamulira kayendedwe ka madzi, kuthamanga, ndi komwe akupita mkati mwa mapaipi. Pakati pa mitundu yambiri yomwe ilipo,mavavu a gulugufeMa valve a gulugufe apeza malo otchuka chifukwa cha kapangidwe kawo kakang'ono, kusinthasintha, komanso kugwiritsa ntchito bwino ndalama. Amapezeka m'mafakitale osiyanasiyana monga kukonza madzi, HVAC, za m'madzi, kupanga magetsi, ndi kukonza mankhwala, ma valve a gulugufe amapangidwa kuti apereke magwiridwe antchito odalirika pamitundu yosiyanasiyana ya ntchito.
Mosiyana ndi njira zina zazikulu monga ma valve a chipata kapena globe, ma valve a gulugufe ndi opepuka, safuna malo ambiri oyika, ndipo amatha kugwira mapaipi akuluakulu mosavuta. Nkhaniyi ikufotokoza zinthu zofunika kwambiri za ma valve a gulugufe — kuyambira pa kapangidwe kawo ndi mfundo zogwirira ntchito mpaka mitundu yawo, ubwino, zofooka, ndi ntchito zawo.
Kapangidwe Koyambira & Mfundo Yogwirira Ntchito
Zigawo Zazikulu
Vavu ya gulugufe ndi yosavuta kupanga koma imagwira ntchito bwino kwambiri. Zinthu zofunika kwambiri ndi izi:
-
Thupi- Kawirikawiri chozungulira, chopangidwa kuti chigwirizane pakati pa mapaipi awiri olumikizirana.
-
Disiki- Chinthu chachikulu chomwe chimazungulira kuti chitsegule kapena kuletsa kuyenda kwa madzi.
-
Tsinde (kapena shaft)- Amalumikiza chogwirira kapena chogwirira ku diski, ndikutumiza mphamvu.
-
Mpando- Imapereka kutseka pakati pa diski ndi thupi la valavu, nthawi zambiri yopangidwa ndi ma elastomer kapena zinthu zina zolimba.
-
Chogwirira kapena chogwirira- Amagwiritsidwa ntchito kuzunguliza diski, yomwe ingakhale yamanja, yoyendetsedwa ndi mpweya, yamagetsi, kapena yamadzimadzi.
Momwe Zimagwirira Ntchito
Mfundo yogwirira ntchito ndi yosavuta: kutembenuza diski kotala (90°) kumasuntha valavu kuchoka pa kutseguka kwathunthu kupita ku kutsekedwa kwathunthu.
-
Potseguka, diskiyo imafanana ndi kayendedwe ka madzi, zomwe zimachepetsa kukana.
-
Mu malo otsekedwa, diskiyo imakhala yopingasa, yotsekereza kuyenda konse.
Kuchita kotala kotala kumeneku kumathandiza kuti ntchito igwire ntchito mwachangu poyerekeza ndi ma valve okwera a stem gate kapena ma valve ozungulira, omwe amafunika kutembenuka kangapo.
Mitundu ya Ma Vavu a Gulugufe
Vavu ya Gulugufe Yokhazikika (Yokhazikika Molimba)

Zipangizo ndi Zomangamanga
Zipangizo za Thupi
-
Chitsulo choponyedwa- Yotsika mtengo, imagwiritsidwa ntchito kwambiri m'madzi.
-
Chitsulo chopangidwa ndi ductile- Yolimba kuposa chitsulo chopangidwa ndi chitsulo, yomwe imapereka mphamvu zabwino.
-
Chitsulo cha kaboni- Yoyenera kugwiritsidwa ntchito pochiza kuthamanga kwa magazi ndi kutentha kwambiri.
-
Chitsulo chosapanga dzimbiri- Amapereka chitetezo ku dzimbiri m'malo okhala ndi mankhwala ndi nyanja.
Zipangizo za Disc
-
Chitsulo chosapanga dzimbiri- Yolimba ndi dzimbiri, yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.
-
Mkuwa kapena aluminiyamu- Yabwino kugwiritsa ntchito m'madzi a m'nyanja.
-
Aloyi wa nikeli- Imapirira kukhudzidwa kwambiri ndi mankhwala.
Zipangizo za Mpando

EPDM (Ethylene Propylene Diene Monomer)- Zabwino kwambiri pamadzi, sizoyenera ma hydrocarbon.
-
NBR (Rabala ya Nitrile)- Yosagonjetsedwa ndi mafuta ndi mafuta.
-
PTFE (Polytetrafluoroethylene)- Mankhwala osagwira ntchito, omwe amagwiritsidwa ntchito mu ntchito za mankhwala amphamvu.
-
Mipando yachitsulo- Chofunika kwambiri pakugwiritsa ntchito kutentha kwambiri.
Ubwino wa Ma Vavu a Gulugufe
-
Yaing'ono komanso yopepuka- Imafuna malo ochepa oyikapo kuposa ma valve a chipata kapena globe.
-
Yotsika mtengo- Kutsika mtengo kwa zinthu ndi kupanga, makamaka m'ma dayamita akuluakulu.
-
Kugwira ntchito mwachangu- Kusuntha kwa kotala la kutembenuka kumathandiza kutsegula/kutseka mwachangu.
-
Kulamulira bwino kayendedwe ka madziNgakhale kuti makamaka ma valve odzipatula, amathanso kuyenda bwino.
-
Kusinthasintha- Ingagwiritsidwe ntchito pa ntchito zamadzimadzi, gasi, ndi matope.
-
Kutsika kwa kuthamanga kwa magazi– Diski ikatsegulidwa bwino, imapangitsa kuti madzi asayende bwino.
-
Kusinthasintha- Imapezeka mu mawonekedwe a wafer, lug, ndi flanged kuti igwiritsidwe ntchito m'njira zosiyanasiyana.
Zolepheretsa ndi Zovuta
-
Kupanikizika ndi kuchepetsa kutentha- Mapangidwe okhala olimba sali oyenera mikhalidwe yovuta kwambiri.
-
Mavuto otseka- Mu ntchito zina, kutseka kwa bubble-tight kungakhale kovuta.
-
Zoletsa kukakamiza- Kugwedeza kwa nthawi yayitali pamalo otseguka pang'ono kungayambitse kugwedezeka kwa ma disc ndi cavitation.
-
Kutsekeka komwe kungatheke- Ngakhale ikatsegulidwa kwathunthu, diski imakhalabe munjira yoyendera, zomwe zingalepheretse machitidwe ena osavuta kumva.
Kumvetsetsa zofooka izi ndikofunikira kwambiri posankha mtundu woyenera wa valavu pazochitika zinazake.
Mapulogalamu Ogwira Ntchito M'makampani Onse
-
Kupereka Madzi ndi Kusamalira Madzi Otayira- Kupatula ndi kulamulira kayendedwe ka madzi m'mapaipi, m'malo osungira madzi, ndi m'malo oyeretsera madzi.
-
Kupanga Mphamvu- Kuziziritsa madzi, kusamalira mafuta, ndi ntchito zoyendera nthunzi.
-
Zomera Zamankhwala ndi Zamafuta- Kuthana ndi mankhwala amphamvu okhala ndi mapangidwe okhala ndi PTFE kapena zitsulo.
-
Zam'madzi ndi Zombo Zomanga- Machitidwe a madzi a m'nyanja, njira zowongolera ballast, chitetezo cha moto.
-
HVAC ndi Machitidwe Omanga- Kuwongolera bwino kayendedwe ka madzi m'madzi ozizira, otenthetsera, ndi makina opumira mpweya.
Kutha kwawo kugwira ntchito ndi ma diameter akuluakulu pamtengo wotsika kumawapangitsa kukhala ofunikira kwambiri pa ntchito zomanga ndi mafakitale.
Zofunikira Zosankha
-
Mtundu wa Valavu- Yozungulira, yozungulira kawiri, kapena yozungulira katatu, kutengera kupanikizika ndi kutentha komwe kukufunika.
-
Kugwirizana kwa Zinthu- Thupi, diski, ndi mipando ziyenera kugwirizana ndi madzi ogwiritsidwa ntchito.
-
Kukula ndi Kalasi Yopanikizika- Onetsetsani kuti mukutsatira malangizo ndi miyezo ya mapaipi.
-
Zofunikira pa Kusindikiza- Sankhani ngati kutseka kokhala ndi mipando yofewa kapena yokhala ndi mipando yachitsulo ndikofunikira.
-
Njira Yogwiritsira Ntchito- Manja, pneumatic, electric, kapena hydraulic, kutengera zosowa za automation.
-
Miyezo ndi Ziphaso- Tsimikizirani kuti mukutsatira miyezo ya ISO, API, ASME, kapena gulu la m'madzi momwe zingakhalire.
