Valavu yosindikizidwa yosindikizidwa: Msungwana wodalirika wamapaipi

Valavu yosindikizidwa yokhazikika ya mpira ndi ma valve apamwamba kwambiri mumunda wamafakitale. Ndi kapangidwe kake ndi magwiridwe antchito abwino, yakhala chisankho chabwino kwa machitidwe ambiri papaipi pansi pamavuto ogwirira ntchito.

Mapangidwe ake ndi okonzeka, ndipo magawowo amakhazikika mkati mwa valavu kudutsa pansi ndi m'munsi mwa makosi otsika, ngakhale atakumana ndi madzi okhazikika osamukaka. Mpando wa Valve umatengera mapangidwe oyandama, nthawi zambiri amapanga mphete zachitsulo, mphete zosindikizira, mphete za o-mphete, Springs ndi zigawo zina. Mukamagwira ntchito, sing'anga ya sing'anga imakankhira mwala valavu kuti ikhale yolimba, pomwe masika amapereka mphamvu yowonjezera, ndikuwonetsetsa kuti abweletse njira zoyambira komanso kutsitsa. Palibe chifukwa chodera nkhawa za kuwongolera kolowera pokhazikitsa. Mwachitsanzo, m'mapaipi achilengedwe okwera kwambiri, ma kwini okhazikika a ma dolves osindikizidwa osindikizidwa amachititsa kuti ntchito yovomerezeka ikhale yovuta kwambiri.

Njira yosindikizira ya valavu yosindikizidwa yosindikizidwa ya mpira sisanafanane. Malo osindikizira a malo ndi mwala wazitsulo amapangidwa ndi zitsulo ndipo amachiritsa ena, monga kupumula kwapadera kuwotcha, etc. kuuma kwamphamvu kumatha kufikira hrc60 kapena kumwamba. Njira yolimba yogulirana ikutha kuvala valavu ndi kupewetsa kukana, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito media yokhala ndi tinthu tokhala ndi michere, monga michere yamapaipi. Tizilombo tating'onoting'onoting'ono tisavale kwambiri valavu, pomwe ma valve olimba osindikizidwa amatha kupewa kukokoloka ndikuwonetsetsa kuti kusindikiza ndi malo awo okhazikika. Nthawi yomweyo, mavu ambiri amatengera masitepe osindikizira omwe ali ndi ma springs kapena kutsitsa kwa masika, komwe kumatha kuyamwa mpirawo ndi kutseka kwamphamvu ndikutseka kwa mavunsi pansi pa kutentha kwambiri. Kutentha koyenera kumatha kufikira 550 ℃ kapena ngakhale.

Mamanja olimba osindikizidwa a mpira amatenga gawo lofunikira m'makampani monga mafuta ndi mpweya, mankhwala, zitsulo, ndi mphamvu. M'makampani opanga mafuta ndi gasi, amatha kuwongolera kutuluka kwa mawonekedwe amkati, kudula ndikuteteza mapiri okwera mtunda wautali, komanso njira zamagetsi zamatawuni; Mu gawo la mainjiniya ukadaulo wa zamankhwala, kaya ndi mayendedwe azomwe amayendetsa bwino kwambiri acid-baseji kapena kutentha kwa kutentha kwambiri komanso kudyetsa riyakitala kwambiri, kumatha kugwira ntchito bwino kwambiri; M'malo opanga zitsulo, mapaipi omwe amagwiritsidwa ntchito pofalitsa nkhani zapadera ngati mpweya wa ng'anjo ya ntchentche; M'magulu opanga magetsi, kupezeka kwake kumatha kuwoneka m'mapaipi a nyukiliya yayikulu yamagetsi ndi kutentha kwamphamvu kwamafuta opangira mafuta.

Maumboni olimba osindikizidwa a mpira, okhala ndi mawonekedwe okhazikika, kusindikiza kodalirika, kutentha kwambiri komanso kukakamizidwa mosalekeza, ndikuwathandiza kwambiri pakupanga mafakitale osiyanasiyana.
