Kuwona Zamapangidwe a Ma Vavu A Mipando Yawiri Yophulika-Umboni Wambiri

I. Zomangamanga

1. Mapangidwe osaphulika

Chowotcha chamagetsi cha valavu yamagetsi oletsa kuphulika kwa mipando iwiri imatenga mawonekedwe osaphulika ndipo imatha kugwira ntchito motetezeka m'malo oyaka ndi kuphulika. Zimaphatikizapo:
(1) Galimoto yosaphulika: Galimoto yosaphulika imagwiritsidwa ntchito kuletsa mota kuti isapange zopsereza panthawi yogwira ntchito.
(2) Woyang'anira wosaphulika: Wowongolera amakumana ndi zotsimikizira kuphulika ndipo amatha kulandira ndi kutulutsa zidziwitso mosamala.
(3) Bokosi lophatikizira lopanda kuphulika: Bokosi lolumikizira lili ndi ntchito yabwino yosindikiza kuti mpweya wophulika wakunja usalowe.

2. Kapangidwe ka mipando iwiri

Valavu yamagetsi yoletsa kuphulika kwa mipando iwiri imakhala ndi mipando iwiri yokhala ndi izi:
(1) Pakatikati pa valve: Mitsempha yapamwamba ndi yapansi imatengera kapangidwe kameneka kuti achepetse mphamvu ya sing'anga pakatikati pa valve ndikuwongolera kusintha kwa valve.
(2) Kusindikiza kawiri: Mipando yam'mwamba ndi yapansi ya valve imapanga chisindikizo chapawiri kuti iteteze bwino kutayikira ndi kupititsa patsogolo ntchito yosindikiza.
(3) Kukonzekera kosavuta: Mapangidwe a mipando iwiri amathandizira kusinthidwa kwa valavu yapakati ndi mpando wa valve, kuchepetsa kuvutika kwa kukonza.

3. Kusankha zinthu

Kusankhidwa kwazinthu zazikuluzikulu monga thupi la valve, core valve, mpando wa valve, ndi zina zotero ndi izi:
(1) Thupi la vavu: zosagwira dzimbiri komanso zosavala ngati chitsulo cha carbon ndi chitsulo chosapanga dzimbiri.
(2) Valve pachimake: zida zosavala ngati chitsulo chosapanga dzimbiri ndi aloyi yolimba.
(3) Mpando wa vavu: zosagwira dzimbiri komanso zosavala ngati PTFE ndi PPL.

II. Mfundo yogwira ntchito

1. Kulandira chizindikiro

Magetsi osaphulika okhala ndi mipando iwirivalve yoyendetsaamasintha kutsegulira kwa valve malinga ndi momwe ntchito ikugwirira ntchito polandira zizindikiro kuchokera ku dongosolo lolamulira kapena sensa.

2. Kuyendetsa galimoto

Pambuyo polandira chizindikirocho, galimoto yotsimikizira kuphulika imayendetsa giya yochepetsera kuti itumize kusuntha kwa valve.

3. Vavu pachimake kusamutsidwa

Tsinde la valve limayendetsa pachimake cha valve kusunthira mmwamba ndi pansi, kusintha malo oyenda pakati pa valavu ndi mpando wa valve, motero kusintha kayendedwe kapakati.

4. Ndemanga chizindikiro

Panthawi yosunthira pakati pa valve, chipangizo choyankha chimabwezeretsanso malo enieni a valve pachimake ku dongosolo lolamulira kuti zitsimikizire kusintha kolondola kwa valve.

5. Kusintha kosindikiza

Kukonzekera kwa mipando iwiri kumapangitsa kuti valavu ikhale yogwira ntchito bwino yosindikiza panthawi yokonza ndikuchepetsa kutaya.

Valavu yoyang'anira mipando yamagetsi yokhala ndi kuphulika kwapawiri imagwira ntchito yofunika kwambiri pamakampani oyaka moto komanso ophulika omwe ali ndi mawonekedwe ake apadera komanso magwiridwe antchito abwino kwambiri. Mapangidwe ake osaphulika, mawonekedwe okhala ndi mipando iwiri, kusintha kolondola komanso kukonza kosavuta kumapangitsa kukhala chisankho chabwino pamakina owongolera makina opanga mafakitale. Pogula valavu yowonongeka yamagetsi yamagetsi awiri, ogwiritsa ntchito ayenera kuyang'anitsitsa zinthu monga kuphulika kwake, kapangidwe kake, ndi kusankha zinthu kuti atsimikizire kuti valavuyo imakhala yotetezeka, yokhazikika komanso yolondola.
