Kuyerekeza ma valve osatha ntchito ndi ma valve wamba

Pali mavuto ambiri ofala ndi ma valve, makamaka omwe amapezeka nthawi zambiri m'mafakitale. Ma valve a ma valve ambiri amapangidwa ndi rabara yopangidwa, yomwe imakhala ndi ntchito yoipa, zomwe zimapangitsa kuti zinthu zogwirira ntchito ziziziritsa kwambiri, kutentha kosayenera ndi kupanikizika, ndi zina zotero; kulongedza konse kumayikidwa pamalo osungira, ndipo kukangana kwamkati kumakhala kwakukulu; kulongedza kumagwiritsidwa ntchito kwa nthawi yayitali. Kukalamba; ntchito ndi yoopsa kwambiri; tsinde la valve lili ndi dzimbiri, kapena lachita dzimbiri chifukwa chosowa chitetezo panja, ndi zina zotero, zomwe zimayambitsa mavuto a ma valve.

Chikwama cha valavu chavalavu yosathaMndandandawu umapangidwa ndi rabala yosatha kutha, yomwe siipezeka kawirikawiri kuti ituluke. Imasakanizidwa ndi zowonjezera zochepa za nano-scale ndi latex yachilengedwe mu mkhalidwe wonyowa (raba yachilengedwe). Mkaka ndi wosavuta kusakaniza mu mkhalidwe wamadzimadzi), kusakaniza kumakhala kofanana, ndipo kuchuluka kwa rabala yachilengedwe ndi pafupifupi 97%, kotero kuti unyolo wautali wa mamolekyu a rabala umakhalabe wosasintha, ndipo kukana kwake kutha ndi kutha kwake kumakhala kowirikiza ka 10 kuposa rabala wamba, kotero ili ndi magwiridwe antchito amphamvu kwambiri ndipo ndi yoyenera pazinthu zosiyanasiyana zowononga. Ili ndi kutha kwamphamvu ndipo imatha kuchepetsa kukangana, kotero ingagwiritsidwe ntchito kwa nthawi yayitali. Mavuto a dzenje ndi dzimbiri a tsinde la valve amafunika chitetezo cha tsiku ndi tsiku ndi ogwiritsa ntchito.

Kuphatikiza apo, magwiridwe antchito otseka a valavu yayikulu siabwino, ndipo sangathe kupirira kukhudzidwa ndi zinthu zoyendera mwachangu; mphete yotsekera sigwirizana bwino ndi mpando wa valavu ndi mbale ya valavu; kutseka kwake ndi kwachangu kwambiri, ndipo pamwamba potsekera sikugwirizana bwino; zinthu zina, pang'onopang'ono mutatseka. Kuziziritsa kumayambitsa mipata yopyapyala pamwamba potsekera, zomwe zimapangitsa kuti pakhale kukokoloka ndi mavuto ena. Rabala yosatha muvalavu yosathaImagwiritsa ntchito ukadaulo wa vulcanization wa pafupipafupi kutentha kwa chipinda panthawi ya vulcanization, kotero kuti rabara yokhala ndi pansi yayikulu yokhuthala imatenthedwa ndikuwotchedwa mofanana mkati ndi kunja nthawi yomweyo, vulcanization imakhala yofanana, pamwamba pake ndi posalala, ndipo mphamvu yake yolimba ndi yolimba. Kulimba kwambiri, imatha kuyamwa, kubweza kugwedezeka, kukangana ndi magwiridwe antchito otseka. Palibe vuto ndi magwiridwe antchito otseka, ili ndi malo osalala, ndipo siyimayambitsa kukhudzana koyipa kwa pamwamba potseka chifukwa chotseka mwachangu kwambiri.

Palinso zifukwa zina, kaya ndi valavu yayikulu kapenavalavu yosatha, wogwiritsa ntchito ayenera kutenga njira zodzitetezera ndi kugwiritsa ntchito bwino, monga: nyengo ikazizira, valavu sichita njira zodzitetezera, zomwe zimapangitsa kuti thupi la valavu lisweke; kugwedezeka kapena kutalika Gudumu lamanja limawonongeka chifukwa cha kugwira ntchito mwamphamvu kwa lever; mphamvu yosalingana pokanikiza paketi, kapena gland yolakwika imapangitsa kuti gland yonyamula katundu isweke ndi zina zotero.
