Mavavu opangira ma turbine mpira amagwiritsidwa ntchito kwambiri m'mafakitale ambiri, kuphatikiza mankhwala, mafuta, gasi, zitsulo, kupanga mapepala, ndi mankhwala. Zawo dongosolo losavuta, ntchito yabwino yosindikiza, moyo wautali wautumiki, komanso kukonza kosavuta kuwapanga kukhala zida zofunika zowongolera kuyenda kwa media mumayendedwe a mapaipi. Monga gawo lofunikira la valavu ya mpira wa turbine, the kusindikiza ntchito ya gearbox zimakhudza mwachindunji ntchito yake yoyenera ndi moyo wautumiki. Chifukwa chake, kupititsa patsogolo ntchito yosindikiza ya gearbox ndipo kukulitsa nthawi yake yokonza ndizofunika kwambiri.

Ma valve a mpira wa pneumatic amagwiritsidwa ntchito mochulukira m'makina amakono owongolera makina opangira mafakitale, ndipo kuyankha kwawo mwachangu komanso kolondola ndikofunikira pakuwonetsetsa kuti dongosolo likuyenda bwino.

Chifukwa cha malo ake apadera ogwirira ntchito, makampani a petrochemical amaika zofunikira kwambiri pachitetezo cha zida. Monga gawo lofunikira pakuwongolera kutuluka kwamadzi m'malo omwe atha kuphulika, ma valve a mpira wamagetsi osaphulika amafuna Chitsimikizo cha ATEX, muyezo wofunikira wachitetezo.

M'madera otentha kwambiri a mafakitale, ma valve olimba osindikizira omwe amagwira ntchito pamwamba pa 800 ° C amagwira ntchito yofunika kwambiri. Kuonetsetsa kudalirika kwawo ndi kusindikiza ntchito zawo pansi pazovuta kwambiri, zatsopano matenthedwe mapindikidwe chipukuta misozi nyumba ndi zofunika kwambiri.

M'munda wa mafakitale, chidutswa chimodzi welded mpira mavavu, amadziwikanso kuti mavavu a mpira opangidwa bwino, amagwiritsidwa ntchito kwambiri mumayendedwe a mapaipi m'mafakitale ambiri, kuphatikiza mafuta, mankhwala, gasi, ndi Kutentha, chifukwa cha ntchito yawo yabwino yosindikiza komanso kukana kupanikizika kwakukulu ndi kutentha kwakukulu.

Amphamvu zidulo ndi alkalis amagwiritsidwa ntchito kwambiri m'mafakitale ambiri, monga petrochemicals, metallurgy, ndi pharmaceuticals. Zofalitsa zowononga izi zimafuna kwambiri zida.

Ma valve a mpira omwe ali ndi fluorine, monga njira yothetsera ma valve, akhala odalirika kwa makampani ambiri chifukwa cha kukana kwawo kwa dzimbiri.

M'mafakitale monga mankhwala ndi electroplating, mavavu a anti-corrosion mpira okhala ndi fluorine amayamikiridwa kwambiri chifukwa cha kukana kwawo kwa dzimbiri.

PTFE (polytetrafluoroethylene) kukaniza kumagwira ntchito yofunika kwambiri kuwonjezera moyo wa chisindikizo za mavavu a mpira.

M'zaka zaposachedwa, dziko langa ndondomeko zoteteza chilengedwe zakhala zolimba kwambiri, ndipo kufunikira kwa zinthu zowononga chilengedwe kukupitilira kukwera m'mafakitale osiyanasiyana. M'makampani a valve, PE pulasitiki valavu mpira, monga mtundu watsopano wa vavu wokonda zachilengedwe, pang'onopang'ono akopa chidwi chofala.

Mu ulimi wamthirira wamakono, PE pulasitiki valavu mpira akukhala otchuka kwambiri chifukwa cha kupepuka kwawo kwapadera komanso kukana kwa mankhwala. Nkhaniyi ifotokoza za ubwino wa ma valve a pulasitiki a PE pamakina a ulimi wothirira komanso momwe zinthuzi zingagwiritsidwire ntchito kuti ulimi wothirira ukhale wabwino komanso zokolola.

Pankhani ya zomangamanga zam'madzi, kusankha ma valve ndikofunikira, pakati pawo 316 zitsulo zosapanga dzimbiri zitsulo ndi 304 zitsulo zosapanga dzimbiri zitsulo ndizosankha zofala. Komabe, dzimbiri za mavavu a mpira wosapanga dzimbiri ndi kuchuluka kwa ayoni a kloridi m'malo am'madzi ndi vuto lalikulu, lomwe lingakhudze magwiridwe antchito ndi moyo wautumiki wa mavavu, komanso kuwopseza ntchito yotetezeka komanso yokhazikika ya dongosolo lonse laumisiri wapamadzi. Tiyeni tikambirane mwatsatanetsatane mmene zinthu ziwiri zosapanga dzimbiri mpira mavavu m'nyanja ndi njira yothetsera dzimbiri chloride ion.
