Valve ndi gawo lowongolera mumayendedwe oyendetsa madzimadzi, omwe ali ndi ntchito zodulira, kuwongolera, kusokoneza, kupewa kuthamangitsidwa, kukhazikika, kusokoneza kapena kusefukira komanso kuchepetsa kupanikizika.Mavavu omwe amagwiritsidwa ntchito m'makina owongolera madzimadzi, kuyambira ma valve osavuta otsekera mpaka ma valve osiyanasiyana omwe amagwiritsidwa ntchito m'makina ovuta kwambiri owongolera, amakhala ndi mitundu yosiyanasiyana komanso mawonekedwe.
Mitundu yosiyanasiyana ya mapaipi imagwiritsa ntchito mavavu amakina okhala ndi zida zosiyanasiyana, mapangidwe, ntchito, ndi njira zolumikizirana.Chifukwa chake, pali nthambi zogwira ntchito komanso ziwombankhanga mkati mwa ma valve amakina, omwe ali ndi zabwino zake, zovuta komanso magawo ogwiritsira ntchito.Akatswiri amayenera kusankha ma valve amakina malinga ndi zosowa zenizeni za makina opangira mapaipi., Kuonetsetsa kuti kayendetsedwe kokhazikika kachitidwe ka mapaipi.
Valve ya Globe:
Valavu yotseka imakhala ndi dongosolo losavuta.Ndizosavuta komanso zosavuta ngati ndikusonkhanitsa, kugwiritsa ntchito, kugwira ntchito ndi kukonza, kugawanitsa mumayendedwe a mapaipi, kapena kuyang'anira kupanga ndi kuwunika kwapamwamba pafakitale;kusindikiza kumakhala bwino, ndipo moyo wautumiki mu dongosolo la mapaipi ndi wautali Izi ndichifukwa choti diski ndi kusindikiza pamwamba pa valve yotseka ndizokhazikika, ndipo palibe kuvala komwe kumachitika chifukwa cha kutsetsereka;nthawi yambiri komanso yogwira ntchito, izi ndi chifukwa chakuti diski yowonongeka ndi yaifupi ndipo torque ndi yaikulu, ndipo zimatengera mphamvu ndi nthawi kuti mutsegule valve yotseka;Kukaniza kwamadzimadzi kumakhala kwakukulu, chifukwa njira yamkati ya valve yotseka imakhala yopweteka kwambiri pamene ikuyang'anizana ndi madzi, ndipo madziwa amafunika kuwononga mphamvu zambiri podutsa valavu;kayendedwe ka madzimadzi ndi amodzi, ndipo ma valavu omwe amatsekedwa panopa pamsika amatha kuthandizira njira imodzi Sunthani, musagwirizane ndi njira ziwiri komanso pamwamba pa kusintha.
Vavu ya Gate:
Kutsegula ndi kutseka kwa valve yachipata kumatsirizidwa ndi mtedza wapamwamba ndi chipata.Potseka, imadalira mphamvu yamkati yamkati kuti izindikire kukanikiza kwa chipata ndi mpando wa valve.Potsegula, imadalira nati kuti izindikire kukweza chipata.Ma valve a zipata amakhala ndi kusindikiza bwino komanso kutseka, ndipo nthawi zambiri amagwiritsidwa ntchito pamapaipi okhala ndi mainchesi oposa 50 mm.Kupanikizika kumagwiritsidwa ntchito kuzindikira kukanikiza kwa chipata ndi mpando wa valve, ndipo mtedza umagwiritsidwa ntchito kuzindikira kukweza kwa chipata pamene chatsegulidwa.Mavavu a pachipata amakhala ndi kusindikiza bwino komanso kudula, ndipo nthawi zambiri amagwiritsidwa ntchito pamapaipi okhala ndi mainchesi akulu kuposa 50 ㎜
Pakati.Ntchito yopondereza imagwiritsidwa ntchito kwambiri mumafuta, gasi, ndi mapaipi operekera madzi
Valve ya mpira:
Valve ya mpira imakhala ndi magwiridwe antchito osintha momwe madzi amayendera komanso kuthamanga kwake, ndipo imakhala ndi ntchito yosindikiza kwambiri.Mphete yosindikizira imapangidwa makamaka ndi PTFE monga chinthu chachikulu, chomwe chimagonjetsedwa ndi dzimbiri pamlingo wina, koma kukana kutentha kwakukulu sikokwera kwambiri, kupitirira kutentha koyenera Kukalamba kumathamanga kwambiri, ndipo kudzakhudza zotsatira zosindikiza. cha valve ya mpira.Choncho, valavu ya mpira ndi yoyenera kwambiri kusintha kwa magawo awiri, kukana kwamadzimadzi pang'ono, zofunika kwambiri zomangira, ndi malire a kutentha kwapakati pa mlingo wina wa mapaipi.Universality ndi yotsika, ndipo ndi yoyenera kunthambi zambiri zamakina komanso zofunikira zambiri zogwirira ntchito.Kugwiritsa ntchito mapaipi okwera sikofunikira pamapaipi owongoka, palibe chifukwa choyendera njira yamadzimadzi, kuchuluka kwa mayendedwe, ndi kutentha kwamadzimadzi kumakhala kokwera kwambiri pamapaipi, zomwe zimawonjezera kutsika kwamitengo.
Valve ya butterfly:
Vavu yagulugufe imatengera kapangidwe kake kokhazikika, kotero kukana kwamadzimadzi kumakhala kochepa kwambiri mukamagwiritsa ntchito mapaipi.Vavu ya butterfly imagwiritsa ntchito ndodo kuti igwiritse ntchito valavu.Valavu imatsekedwa ndipo imatsegulidwa osati kukweza, koma mozungulira, kotero kuti mlingo wa kuvala ndi wotsika ndipo moyo wautumiki ndi wautali.Mavavu agulugufe nthawi zambiri amagwiritsidwa ntchito pamapaipi otenthetsera, gasi, madzi, mafuta, asidi ndi kayendedwe ka madzi amchere.Ndi mavavu amakina okhala ndi kusindikiza kwakukulu, moyo wautali wautumiki, komanso kutayikira kochepa.
