Chidziwitso chodziwika cha valavu ya mpira wa PVC
Mavavu a mpira a PVC atha kugwiritsidwa ntchito kuwongolera ndikuwongolera kutuluka kwamadzimadzi kuphatikiza kugwiritsidwa ntchito makamaka kujowina kapena kulumikiza media zamapaipi.Zimapereka ubwino wotsatira pa ma valve ena.Pali kukana madzimadzi pang'ono.Pakati pa ma valve onse, valavu ya mpira imakhala ndi mphamvu zochepa zamadzimadzi.Kukaniza kwake kwamadzimadzi ndikotsika kwambiri, ngakhale kuti ndi valavu ya mpira yokhala ndi mainchesi ochepa.
Mtundu watsopano wavalavu ya mpira yopangidwa ndi UPVCadapangidwa kuti akwaniritse zofunikira zamadzimadzi am'mapaipi osiyanasiyana owononga.Ubwino wa valavu ya valavu umaphatikizapo kulemera kwake kochepa, kukana kwa dzimbiri, kamangidwe kameneka, maonekedwe okondeka, kuyika mosavuta, ntchito zosiyanasiyana, zomangamanga zaukhondo komanso zopanda poizoni, kukana kuvala, kuphweka kwa disassembly, komanso kukonza mosavuta.
PPRPVDF, PPH,Mtengo wa CPVC, ndi zipangizo zina za pulasitiki zimagwiritsidwanso ntchito popanga ma valve a pulasitiki a mpira kuwonjezera pa PVC.Mavavu a mpira opangidwa ndi PVC ali ndi kukana kwapadera kwa dzimbiri.Pogwiritsa ntchito F4, mphete yosindikiza imasindikiza.Moyo wautali wautumiki chifukwa cha kukana kwa dzimbiri.Kasinthasintha kothandiza komwe kumasinthasintha.
Monga valavu yophatikizika ya mpira, theValve ya mpira wa PVCimapereka magwero ochepa a kutayikira, mphamvu zambiri, ndipo ndi yosavuta kusonkhanitsa ndi kusokoneza.Kuyika ma valve a mpira ndi kugwiritsa ntchito: Kupewa kutayikira komwe kumabwera chifukwa cha kupunduka kwa ma flanges, mabawuti ayenera kumangidwa chimodzimodzi pamene mbali zonse ziwiri zatsekeredwa paipi.Itha kugwiritsidwa ntchito podutsa ndi kudutsa, ndipo kusintha kwakuyenda sikugwira ntchito.Zamadzimadzi zomwe zimakhala ndi tinthu tolimba zimatha kukanda mosavuta pamwamba pa bwaloli.

Chitsanzo choyambirira chofanana ndivalavu ya mpirandi valavu yovomerezeka ndi John Warren mu 1871. Ndi valavu yokhala ndi zitsulo yokhala ndi mpira wamkuwa ndi mpando wamkuwa.Pambuyo pake Warren adapereka chiphaso chake cha valve ya mpira wamkuwa kwa John Chapman, wamkulu wa Chapman Valve Company.Ziribe chifukwa chake, Chapman sanayikepo mapangidwe a Warren pakupanga.M'malo mwake, iye ndi ena opanga ma valve akhala akugwiritsa ntchito mapangidwe akale kwa zaka zambiri.
Ma valve a mpira, omwe amadziwikanso kuti mavavu a tambala a mpira, adagwira nawo ntchito pankhondo yachiwiri yapadziko lonse.Panthawi imeneyi, mainjiniya adapanga izi kuti zigwiritsidwe ntchito pamakina amafuta ankhondo.Pambuyo kupambana kwama valve a mpiramu Nkhondo Yachiwiri Yadziko Lonse, mainjiniya adagwiritsa ntchito mavavu a mpira pamafakitale.
Chimodzi mwazofunikira kwambiri zokhudzana ndi ma valve a mpira m'zaka za m'ma 1950 chinali chitukuko cha Teflon komanso kugwiritsidwa ntchito kwake monga zida za mpira.Pambuyo pa chitukuko chabwino cha Teflon, mabizinesi ambiri monga DuPont adakhala ndi ufulu wogwiritsa ntchito, chifukwa adadziwa kuti Teflon ikhoza kubweretsa phindu lalikulu pamsika.Pamapeto pake, makampani oposa imodzi adatha kupanga ma valve a Teflon.Ma valve a Teflon mpira amatha kusinthasintha ndipo amatha kupanga zisindikizo zabwino mbali ziwiri.M'mawu ena, iwo ndi bidirectional.Komanso ndi umboni wotayikira.Mu 1958, Howard Freeman anali wopanga woyamba kupanga valavu ya mpira yokhala ndi mpando wosinthika wa Teflon, ndipo mapangidwe ake anali ovomerezeka.
Masiku ano, ma valve a mpira apangidwa m'njira zambiri, kuphatikizapo kugwirizanitsa kwawo ndi ntchito zomwe zingatheke.Kuphatikiza apo, amatha kugwiritsa ntchito makina a CNC ndi mapulogalamu apakompyuta (monga mtundu wa Button) kuti apange mavavu abwino kwambiri.Posakhalitsa, opanga ma valve a mpira adzatha kupereka zosankha zambiri za mankhwala awo, kuphatikizapo zomangamanga za aluminiyamu, kuvala pang'ono komanso mphamvu zothamanga kwambiri, zomwe zimalola ogwira ntchito kuti adutse kuchuluka kwamadzimadzi kudzera mu valve pamlingo wochepa wothamanga.
