Vavu ya Mpira Wachikazi: Kapangidwe ndi Kuyambitsa Ntchito
Valavu yamkati ya mpira, yomwe imadziwikanso kuti valavu yamkati ya ulusi kapena ulusi wamkati wa globe valve, ndi mtundu wamba wa valavu. Cholinga chake chachikulu ndikutsegula kapena kutseka njira zamadzimadzi pozungulira madigiri 90. Mfundo yake yogwirira ntchito ndikuwongolera kuyenda kwamadzimadzi kudzera mugawo. Chigawochi chikazungulira molingana ndi mayendedwe a mapaipi, madzimadzi amatha kudutsa; Chigawochi chikazungulira madigiri 90 molunjika ku olamulira a mapaipi, chimadulatu kutuluka kwa madzimadzi.
Makhalidwe amapangidwe
Vavu ya mpira wamkati imakhala ndi zigawo izi:
1. Thupi la valve: Thupi lalikulu la valve, lomwe limagwiritsidwa ntchito polumikiza mapaipi.
2. Sphere: Ili mkati mwa thupi la valve, imatha kuzungulira momasuka ndikuwongolera kutuluka kwa madzi.
3. Tsinde la valve: chosinthira chomwe chimagwiritsidwa ntchito poyendetsa mpira.
4. Handwheel: yomwe nthawi zambiri imakhala kumapeto kwa tsinde la valve, yomwe imagwiritsidwa ntchito potembenuza tsinde la valve.
5. Zisindikizo: Onetsetsani kuti madziwo sakutha pamene ali chotseka.
Mapangidwe a ulusi wamkati amalola kuti valavu ya mpira iyi ilowetsedwe mwachindunji mu payipi, ndikupangitsa kukhazikitsa kosavuta komanso mwachangu. Kuphatikiza apo, chifukwa cha kapangidwe kake kosavuta, kakulidwe kakang'ono, kulemera kopepuka, komanso magwiridwe antchito abwino osindikizira, mavavu a mpira wamkati amagwiritsidwa ntchito kwambiri pamakina a mapaipi m'mafakitale monga mafuta, mankhwala, zitsulo, ndi mphamvu.
epilogue
Ma valve opangidwa ndi ulusi wamkati ndi zida zofunika kwambiri komanso zofunikira m'magawo anyumba ndi mafakitale. Kutuluka kwake kunathandizira kwambiri kupanga ndi moyo wa anthu, kupereka chithandizo champhamvu pakukula kwamakampani amakono.
