Yambitsani
Chotengera cha U-mtundu wa gulugufe chimatenga mawonekedwe okwera, omwe amachepetsa ma bolts olumikizira thupi la valavu lokhala ndi vuto lalikulu komanso lalikulu, kumathandizira kudalirika kwa valavu ndikuthana ndi mphamvu ya kulemera kwanthawi zonse ntchito valavu.
Kukula kwa ntchito
U-mtundu wa valavu wa gulugufe amagwiritsidwa ntchito kwambiri m'makampani opanga malasha, mafakitale a petrochemical, labala, mapepala, mankhwala ndi mapaipi ena monga chida cha shunt confluence kapena chipangizo chosinthira.
Mbale ya gulugufe ya valavu ya gulugufe imayikidwa m'mayendedwe awiri a payipi. Pazitsulo zamagulugufe zamagulugufe, mbale ya gulugufe yozungulira ngati disc imazungulira mozungulira, ndipo mbali yomwe imazungulira imakhala pakati pa 0 ° ndi 90 ° ndipo kasinthasintha akafika 90 ° mbale ya valavu imakhala yotseguka kwathunthu.
Valavu ya gulugufe ndiyosavuta, yaying'ono kukula ndi kulemera kwake, ndipo imangokhala ndi magawo ochepa. Kuphatikiza apo, valavu imatha kutsegulidwa ndikutseka mwachangu masinthidwe a 90 ° okha, omwe ndi osavuta kugwira ntchito. Nthawi yomweyo, valavu ili ndi mawonekedwe abwino owongolera madzimadzi. Valavu ya gulugufe ikakhala pamalo otseguka bwino, kukula kwa mbale ya gulugufe ndiko kukana kokha pamene sing'anga ikuyenda mthupi la valavu, ndiye kuti kutsika komwe kumachitika ndi valavu kumakhala kochepa kwambiri, motero kumakhala ndi mawonekedwe oyendetsa bwino. Gulugufe vavu ali zotanuka chisindikizo ndi chitsulo. Zotanuka zotsekera valavu, kusindikiza mphete kumatha kuvekedwa ndi thupi la valavu kapena kulumikizidwa kumapeto kwa mbale ya gulugufe.
Valavu yokhala ndi chidindo chachitsulo imakhala ndi moyo wautali kuposa momwe imakhalira ndi zotanuka, koma ndizovuta kusindikiza kwathunthu. Chisindikizo chachitsulo chimatha kusintha kutentha kwakanthawi kogwira ntchito, pomwe chisindikizo chotsekera chimakhala ndi malire kutentha.
Ngati valavu yamagulugufe ikufunika kuti igwiritsidwe ntchito poyendetsa, chinthu chachikulu ndikusankha mtundu woyenera wa valavu. Kapangidwe ka vavu gulugufe makamaka oyenera kupanga vavu lalikulu awiri. Valavu ya gulugufe imagwiritsidwa ntchito kwambiri pamafuta amafuta, gasi, mafakitale, mankhwala amadzi ndi mafakitale ena onse, komanso amagwiritsidwanso ntchito pamakina ozizira amagetsi.
