Mfundo yogwira ntchito ya valve ya singano

Valavu ya singano ndi gawo lofunikira pa chipangizo choyezera mapaipi, ndipo ndi valavu yomwe imatha kusintha ndikudula madziwo.Pakatikati pa valve ndi chulucho chakuthwa kwambiri, chomwe chimagwiritsidwa ntchito poyenda pang'ono, mpweya wothamanga kwambiri kapena madzi.Kapangidwe kake ndi kofanana ndi valavu yapadziko lonse lapansi, ndipo ntchito yake ndikutsegula kapena kudula valavu kuti mufikire mapaipi.

1. Kutsegula ndi kutseka kwa valve ya singano ndi kondomu yakuthwa, yomwe imazungulira mozungulira pamene ikutsegula ndi koloko pamene ikutseka.
2. Mapangidwe amkati amafanana ndi valve yoyimitsa, yomwe imakhala yochepa kwambiri komanso yotsika kwambiri.Tsinde la valve limayendetsedwa ndi handwheel.

Kapangidwe ka valavu ya singano
1. Vavu ya singano yokhala ndi chivundikiro cha valve iyenera kusankhidwa pamapaipi ndi chipangizo chapakati chotsika kutentha.
2. Pamapaipi a chothandizira chosweka chagawo loyenga mafuta, valavu ya singano yonyamulira imatha kusankhidwa.
3. Mavavu a singano adzapangidwa ndi chitsulo chosapanga dzimbiri cha austenitic chokhala ndi PTFE monga mphete yosindikizira mpando wa valve mu zipangizo ndi mapaipi okhala ndi zowonongeka monga asidi ndi alkali mu mankhwala.
4. Zitsulo ku zitsulo kusindikiza singano mavavu akhoza kusankhidwa kwa kachitidwe mapaipi kapena zipangizo zamakono kutentha TV kachitidwe zitsulo, kachitidwe mphamvu, zomera petrochemical ndi kachitidwe Kutentha m'tawuni.
5. Pamene kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake kakhoza kusankhidwa.
6. Vavu ya singano yokhala ndi zowotcherera zonse idzagwiritsidwa ntchito potengera payipi yayikulu yamafuta ndi gasi, paipi yoyeretsedwa ndi kukwirira pansi;Kwa iwo okwiriridwa pansi, valavu ya mpira yokhala ndi cholumikizira chowotcherera kapena cholumikizira cha flange chidzasankhidwa.
7. Flange yolumikizidwa ndi singano valve idzasankhidwa paipi yotumizira ndi zida zosungiramo mafuta opangira.
8. Pa mapaipi a gasi wam'tawuni ndi gasi wachilengedwe, mavavu a singano okhala ndi flange ndi kulumikizana kwa ulusi wamkati amasankhidwa.
9. Mu dongosolo la payipi ya okosijeni yazitsulo, valavu ya singano yokhala ndi chithandizo chotsitsa kwambiri komanso kulumikizana kwa flange iyenera kusankhidwa.
10. Valavu ya singano imapangidwa ndi thupi la valve, singano ya singano, kulongedza ndi handwheel.
