Zifukwa Zolephera kwa Mpando wa Valuvu ndi Malangizo Okonzanso Kapangidwe ka Kapangidwe

Nditachita mapulojekiti a ma valve kwa zaka zonsezi, kunena zoona, ndaona mavuto ambiri a mipando ya ma valve. Nthawi zambiri, wogwiritsa ntchito amadandaula za kutuluka kwa ma valve, kwenikweni, si vuto la spool, koma mpando wa ma valve wakhala ukutha kwa nthawi yayitali. Nthawi zina zinthu zake sizili bwino, nthawi zina kapangidwe kake sikanali koyenera kuganizira momwe ntchito ikuyendera.

Poyamba tidayika ma valve a mpira wa chomera chophikira, fumbi, kutentha kwambiri, zojambula zolembedwa pa mpando wofewa wachitsulo chosapanga dzimbiri, zotsatira za ntchito yosakwana theka la chaka, ulendo wobwerera unapeza kuti mayunitsi angapo anali ndi kutayikira kwakukulu mkati. Titachotsa mphete yotsekerayo ndikupeza kuti yakwapulidwa, m'mphepete mwa mpando wa valavu nawonso mwagwa pang'ono. Pambuyo pake tinasintha ndi mpando wa valavu wachitsulo wolumikizidwa mwamphamvu, moyo unawonjezeka ndi zaka zoposa ziwiri.

Pali njira zingapo zodziwika bwino zolephera: imodzi ndi kuwonongeka kwa pamwamba pa chitseko, makamaka ndi tinthu tolimba ta media, kutsegula ndi kutseka pafupipafupi pansi pa kukwapula mwachangu kwambiri; yachiwiri ndi kung'amba kwa weld layer, komwe nthawi zambiri kumakhala kuti njira yopangira pamwamba siili pamalo ake kapena kupsinjika kwa kutentha sikutulutsidwa; palinso vuto lobisika ndi kuti spool ndi seat assembling sizikhala zozungulira, zotsatira zake ndi kuti mbali imodzi ya strain yakale, mbali imodzi ya kutayikira.

Ngati gawo la kapangidwe kake silikutenga mpando wa valavu mozama, mavuto amakhala osapeweka. Tili ndi kasitomala mu mzere wopanga alumina wokhala ndi ma valve ambiri a V-ball, mpando wa valavu ndi chitsulo chosapanga dzimbiri wamba, ukugwira ntchito yosakwana chaka chimodzi pa jamming, kuyeretsa sikungathe kutsukidwa. Pambuyo pake, tinawapatsa mtundu wa taper kuti alimbikitse kapangidwe kake, tinawonjezera malire opindika komanso mzere wothandizira wamkati, womwe umagwira ntchito kwa zaka ziwiri popanda kuwonongeka kwakukulu.

Kapangidwe kake, tikulimbikitsidwa kuti kapangidwe kake kaganizire mfundo zitatu: Choyamba, pamwamba pa chitseko momwe zingathere kuti pakhale chosinthika, vuto likhoza kukonzedwa pamalopo; Chachiwiri, zinthuzo zitha kuyikidwa mu chivundikirocho kuti zisawononge mavuto ndi chitsulo chosapanga dzimbiri chimodzi; Chachitatu, kusonkhana pamodzi ndi malire a pakati, musadalire kulumikizana ndi manja kuti mugwirizane. Kupanda kutero, kusintha pang'ono kwa kukhazikitsa, sinthani kangapo pambuyo poti 'spool' yayamba.

Mu kapangidwe ka mpando wa valve komwe tachita, monga kuphatikiza kwa chitsulo chopindika ndi chotseka cha composite, magwiridwe antchito ake ndi okhazikika kwambiri pakugwira ntchito kwa mafuta a malasha, ammonium phosphate, ndi madzi otayira mchere wambiri. Tsopano makasitomala ambiri aphatikiza mwachindunji kapangidwe kathu kameneka m'maphukusi awo aukadaulo, zomwe zikusonyeza kuti njira yamtunduwu imatha kuthetsa mavuto omwe ali m'munda.

Mpando wa valavu ndi chinthu chomwe palibe amene amachiganizira akamapanga, ndipo ngati china chake chalakwika, ndi nkhani yaikulu. Perekani lingaliro lakuti onse apange, achite zinthu zina zogulira, asamangoyang'ana pepala la deta, kuti amvetsere momwe anthu amagwirira ntchito komanso momwe anganenere. Chifukwa chakuti mikhalidwe yogwirira ntchito siimayembekezera anthu, kapangidwe kake ndi kabwino, kakhazikitsidwa miyezi itatu kuti adziwe.
