Valavu ndi cholumikizira mapaipi chomwe chimagwiritsidwa ntchito potsegula ndi kutseka mapaipi, kuwongolera komwe kumayendera, kuwongolera ndi kuwongolera magawo (kutentha, kuthamanga ndi kuthamanga) kwa sing'anga yotumizidwa. Malinga ndi ntchito yake, imatha kugawidwa kukhala ma valve otseka,fufuzani ma valve, ma valve owongolera, etc.
Ma valve ndi zigawo zowongolera pamakina oyendetsa madzimadzi, omwe ali ndi ntchito zotseka, kuwongolera, kusokoneza, kupewa kubweza, kukhazikika kwapanikizidwe, kupatutsidwa kapena kuchepetsa kupsinjika kwa kusefukira. Mavavu a machitidwe owongolera madzimadzi amachokera ku ma valve osavuta otsekera kupita ku ma valve ovuta kwambiri omwe amagwiritsidwa ntchito mu machitidwe olamulira.
Mavavu amatha kugwiritsidwa ntchito kuwongolera kutuluka kwamitundu yosiyanasiyana yamadzimadzi monga mpweya, madzi, nthunzi, zotengera zosiyanasiyana zowononga, ma slurries, mafuta, zitsulo zamadzimadzi ndi media radioactive. Malingana ndi zinthuzo, ma valve amagawidwansomavavu achitsulo, mavavu zitsulo zosapanga dzimbiri, zitsulo zosapanga dzimbiri (201, 304, 316, etc.), mavavu achitsulo a chrome-molybdenum, mavavu achitsulo a chromium-molybdenum vanadium zitsulo, mavavu achitsulo a duplex, mavavu apulasitiki, mavavu osakhazikika, ndi zina zambiri.
Sankhani
Pa ntchito ndi ntchito
(1) Vavu yotseka
Valavu yamtunduwu imagwiritsidwa ntchito potsegula ndi kutseka. Zimayikidwa kwamuyaya mu malo olowera ndi kutulutsa kutentha ndi kutentha, malo olowera ndi kutuluka kwa zipangizo, ndi mzere wa nthambi za mapaipi (kuphatikizapo okwera), komanso angagwiritsidwe ntchito ngati valavu yotulutsa madzi ndi valavu yotulutsa mpweya. Ma valve otsekera wamba akuphatikizapoma valve pachipata, mavavu a globe, ma valve a mpira ndi ma valve a butterfly.
Ma valve a zipataakhoza kugawidwa mu ndodo yotseguka ndi ndodo yakuda, nkhosa yamphongo imodzi ndi nkhosa yamphongo iwiri, nkhosa yamphongo ndi nkhosa yamphongo yofanana, ndi zina zotero. Kukula kwa valavu ya valve ndi yaying'ono motsatira momwe madzi amayendera, kukana kwamadzi kumakhala kochepa, ndipo kutalika kwadzina kwa valve yachipata ndi kwakukulu.
Malingana ndi kayendetsedwe ka kayendedwe ka sing'anga, valavu yapadziko lonse imagawidwa m'magulu atatu: mtundu wowongoka, mtundu wa mbali yoyenera ndi mtundu wothamanga, ndipo pali ndodo zotseguka ndi ndodo zakuda. Kutsekeka kwa valve yapadziko lonse lapansi ndikwabwinoko kuposa valavu yachipata, thupi la valve ndi lalitali, kukana kwamadzi ndi kwakukulu, ndipo mainchesi apamwamba kwambiri ndi DN200.
Mphuno ya valve ya mpira ndi mpira wotseguka. Tsinde la valve yoyendetsedwa ndi mbale imapangitsa mpirawo kuti utseguke ukayang'anizana ndi mayendedwe a mapaipi, ndipo umatsekedwa kwathunthu ukatembenuza 90 °. Valve ya mpira imakhala ndi kusintha kwina ndipo imatseka mwamphamvu.
Spool yavalavu ya butterflyndi chimbale chozungulira chomwe chimazungulira m'mbali mwa shaft yoyima ya axis ya chitoliro chowongoka. Pamene ndege ya mbale ya valve ikugwirizana ndi olamulira a chitoliro, imatsegulidwa kwathunthu; Pamene ndege yamphongo ndi perpendicular kwa olamulira chitoliro, izo kwathunthu chatsekedwa. Kutalika kwa thupi la agulugufe ndi kakang'ono, kukana koyenda kumakhala kochepa, ndipo mtengo wake ndi wapamwamba kuposa wa ma valve a zipata ndi ma valve a globe.
(2) Chongani valavu
Valavu yamtunduwu imagwiritsidwa ntchito poletsa kubwereranso kwa sing'anga, ndipo imagwiritsa ntchito mphamvu yamadzimadzi yamadzimadzi kuti itsegule yokha ndikutseka yokha ikadutsa mbali ina. Kuyimirira potulukira mpope, potulutsira msampha, ndi malo ena pomwe kutuluka kwamadzi kumaloledwa. Pali mitundu itatu ya ma valve cheke: mtundu wotsegulira wozungulira, mtundu wokweza ndi mtundu wa clamp. Pankhani ya swing check valves, madzimadzi amatha kutuluka kuchokera kumanzere kupita kumanja ndipo amangotseka pamene akuyenda mosiyana. Kwa ma valve okwera, spool imakweza mmwamba kuti ipange njira pamene madzi akuyenda kuchokera kumanzere kupita kumanja, ndipo spool imatsekedwa pamene ikukanikizidwa pampando pamene kutuluka kumabwereranso. Kwa valve yowunikira, pamene madzi akuyenda kuchokera kumanzere kupita kumanja, chigawo cha valve chimatsegulidwa kuti chipange njira, ndipo valavu ya valve imakanikizidwa kumpando wa valve ndikutsekedwa pamene kutuluka kwapakati kumasinthidwa.
(3) Kuwongoleramavavu
Kusiyana kwapakati pakati pa kutsogolo ndi kumbuyo kwa valavu ndi kotsimikizika, ndipo pamene kutsegula kwa valve wamba kumasintha mumtundu waukulu, kuthamanga kwa magazi kumasintha pang'ono, ndipo ikafika pamtunda wina, kuthamanga kumasintha kwambiri. , kusintha kwabwino kumakhala kolakwika. Valve yowongolera imatha kusintha spool stroke kuti isinthe kukana kwa valavu molingana ndi malangizo ndi kukula kwa chizindikirocho, kuti akwaniritse cholinga chowongolera valavu yoyenda. Ma valve owongolera amagawidwa kukhala ma valve owongolera ndi ma valve owongolera okha, ndipo pali mitundu yambiri ya ma valve owongolera kapena odziyimira pawokha, ndipo kusintha kwawo kumasiyananso. Ma valve odzilamulira okha amaphatikizapo ma valve odziyendetsa okha komanso ma valve odzipangira okha.
(4) Vuto
Vacuum imaphatikizapo ma vacuum ball valves, vacuum baffle valves, vacuum inflation valves, vacuum vacuum vacuum valves, ndi zina zotero. Ntchito yake ili mu vacuum system, vacuum system element yomwe imagwiritsa ntchito kusintha kayendedwe ka mpweya, kusintha kayendedwe ka mpweya, kudula. kapena kulumikiza payipi amatchedwa vacuum vavu.
(5) Magulu a cholinga chapadera
Zolinga zapadera zimaphatikizapo mavavu a nkhumba, ma valve otsegulira, ma valve othamangitsira, ma valve otulutsa mpweya, zosefera, ndi zina zotero.
Valavu yotulutsa mpweya ndi gawo lofunikira lothandizira pamapaipi, omwe amagwiritsidwa ntchito kwambiri mu boilers, air conditioners, mafuta ndi gasi, madzi ndi mapaipi a ngalande. Nthawi zambiri imayikidwa pamtunda wolamula kapena pachigono kuti achotse gasi wochulukirapo mupaipi, kukonza bwino ntchito yamapaipi ndikuchepetsa kugwiritsa ntchito mphamvu.
Labala aliyense wokhalavalavu ya butterfly, valavu pachipata, Y-stainer, valavu yoyendera,valavu yowunikira mbale ziwirimafunso, mutha kulumikizana nawovalve TWSfakitale. Komanso mutha kudina patsamba lathu https://www.tws-valve.com/ kuti mumve zambiri.
