Valavu imagwiritsidwa ntchito potsegula ndi kutseka payipi, kuwongolera kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka anthu.Malingana ndi ntchito yake, ikhoza kugawidwa mu valve shutoff, valve valve, valve valve, etc.

Valavu ndi gawo lolamulira mu kayendedwe ka madzimadzi, omwe ali ndi ntchito za kudula, kulamulira, kusokoneza, kulepheretsa kubwereza, kukhazikika kwa mphamvu, kusokoneza kapena kutulutsa mpumulo, ndi zina zotero. omwe amagwiritsidwa ntchito m'makina ovuta kwambiri.

Mavavu angagwiritsidwe ntchito kuwongolera kuyenda kwa mpweya, madzi, nthunzi, zowononga media, matope, mafuta, zitsulo zamadzimadzi ndi ma radioactive media ndi mitundu ina yamadzimadzi.Mavavu malinga ndi zinthuzo amagawidwanso kukhala mavavu achitsulo, mavavu achitsulo, mavavu osapanga dzimbiri (201, 304, 316, etc.), mavavu achitsulo a chromium molybdenum, mavavu a chromium molybdenum vanadium zitsulo, mavavu azitsulo awiri, mavavu apulasitiki. , mavavu osakhala achizolowezi.

Vavu ili mu dongosolo lamadzimadzi, lomwe limagwiritsidwa ntchito kuwongolera njira yamadzimadzi, kuthamanga, kuyenda kwa chipangizocho, ndikupanga chitoliro ndi zida zapakati (zamadzimadzi, gasi, ufa) zikuyenda kapena kuyimitsa ndikuwongolera kuyenda kwa chipangizocho. .

Valve ndi gawo lowongolera la payipi yamadzimadzi yotumizira, yomwe imagwiritsidwa ntchito kusintha gawo la ndimeyi ndi njira yapakati yoyenda, ndi diversion, cut-off, throttle, cheke, diversion kapena kusefukira kwamphamvu yothandizira ntchito.Vavu yomwe imagwiritsidwa ntchito poyang'anira madzimadzi, kuchokera ku valavu yosavuta kwambiri yapadziko lonse kupita ku makina ovuta kwambiri owongolera omwe amagwiritsidwa ntchito mumitundu yosiyanasiyana ya mavavu, mitundu yake ndi mafotokozedwe ake, kukula mwadzina kwa valavu kuchokera ku valavu yaing'ono kwambiri mpaka kukula kwa payipi ya mafakitale. valve mpaka 10m.Angagwiritsidwe ntchito kulamulira madzi, nthunzi, mafuta, gasi, matope, zosiyanasiyana zikuwononga TV, madzi zitsulo ndi radioactive madzimadzi ndi mitundu ina ya madzimadzi otaya, kuthamanga ntchito valavu kungakhale kuchokera 0.0013MPa kuti 1000MPa kopitilira muyeso-mkulu. kuthamanga, kutentha ntchito kungakhale C-270 ℃ wa kopitilira muyeso-otsika kutentha kwa 1430 ℃ kutentha mkulu.

Valavu imatha kuwongoleredwa ndi njira zosiyanasiyana zotumizira, monga manual, magetsi, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic, electro-hydraulic, electro-hydraulic, gas-hydraulic, spur gear, bevel gear drive;Pakukakamiza, kutentha kapena mawonekedwe ena pansi pa ma sensa a sensa, kuchitapo kanthu, malinga ndi kufunikira kwa kusungitsa kapena kusadalira ma sensor a sensor kuti atsegule kapena kutseka, kudalira pagalimoto kapena makina odziwikiratu amapanga valavu yotsegula ndi kutseka. kukweza, kutsetsereka, malo kapena kusuntha kozungulira, kuti musinthe kukula kwa doko kuti muzindikire ntchito yolamulira.
