Valavu Yokhala ndi Malo O ...
Kodi Valavu Yokhala ndi Malo Amodzi Yotani?
Ma valve ozungulira ndi ma valve otseka oyenda molunjika omwe amagwiritsidwa ntchito kuyambitsa, kuyimitsa kapena kuwongolera kuyenda kwa madzi pogwiritsa ntchito chotseka chomwe chimatchedwa disc. Mpando wa valve yozungulira uli pakati ndipo umagwirizana ndi chitoliro, ndipo malo otseguka pampandowo amatsekedwa ndi disc kapena pulagi. Disc yozungulira ya valve imatha kutseka kwathunthu njira yoyendera madzi kapena kuchotsedwa kwathunthu. Malo otseguka a mpando amasintha mofanana ndi kuyenda kwa disc yomwe ndi yoyenera ntchito zokhudzana ndi kayendetsedwe ka madzi. Ma valve ozungulira ndi oyenera kwambiri ndipo amagwiritsidwa ntchito kwambiri kuwongolera kapena kuletsa kuyenda kwa madzi kapena mpweya kudzera mu chitoliro kuti achepetse ndikuwongolera kuyenda kwa madzi ndipo nthawi zambiri amagwiritsidwa ntchito m'mapaipi ang'onoang'ono.
Valavu Yokhala ndi Malo Amodzi Yokhala ndi Malo Amodzi ndi imodzi mwa mapangidwe otchuka kwambiri a mavavu a globe, a US ndi API system. M'mimba mwake, zipangizo, maso ndi maso, makulidwe a khoma, kutentha kwa kupanikizika, zimatanthauzidwa ndi ASME B16.34.
Kuphatikiza apo, kutengera kapangidwe ka mpando ndi diski, malo okhala a Single Seated Globe Valve amatha kuyendetsedwa bwino ndi tsinde lopindika. Mphamvu yotsekera ya Single Seated Globe Valve ndi yayikulu kwambiri. Itha kugwiritsidwa ntchito pa ntchito yopuma. Chifukwa cha mtunda waufupi wa diski pakati pa malo otseguka ndi otsekedwa, Single Seated Globe Valve ndi yabwino ngati valavu iyenera kutsegulidwa ndi kutsekedwa pafupipafupi. Chifukwa chake, mavalavu ozungulira angagwiritsidwe ntchito pa ntchito zosiyanasiyana.
Vavu ya Globe Yokhala ndi Malo Amodzi ingagwiritsidwenso ntchito poyendetsa. Ma valve ambiri okhala ndi malo amodzi amagwiritsa ntchito kapangidwe ka khola kapena kosungira kuti asunge mphete ya mpando, kupereka chitsogozo cha pulagi ya valavu, komanso kupereka njira yokhazikitsira makhalidwe enaake a valavu. Itha kusinthidwa mosavuta posintha magawo odulira kuti asinthe mawonekedwe a mayendedwe kapena kupereka mphamvu yochepa.kuyenda, kuchepetsa phokoso, kapena kuchepetsa kapena kuchotsa cavitation.
Mapangidwe a Thupi la ASME Globe Valve, pali mapangidwe atatu akuluakulu a thupi kapena mapangidwe a ma valve a Globe, omwe ndi:
- 1). Chitsanzo Chokhazikika (chomwe chimadziwikanso kuti Chitsanzo cha Tee kapena T - Chitsanzo kapena Z - Chitsanzo)
- 2). Chitsanzo cha ngodya
- 3). Kapangidwe ka Oblique (komwe kumadziwikanso kuti Kapangidwe ka Wye kapena Kapangidwe ka Y)
Mbali yaikulu ya Valavu Yokhala ndi Malo Amodzi
- 1) .Good kusindikiza mphamvu
- 2). Mtunda waufupi woyenda wa diski (sitiroko) pakati pa malo otseguka ndi otsekedwa,Ma valve a ASME padziko lonse lapansindi abwino ngati valavu iyenera kutsegulidwa ndi kutsekedwa pafupipafupi;
- 3).Vavu ya ASME globe ingagwiritsidwe ntchito ngati valavu yoyimitsa galimoto mwa kusintha kapangidwe kake pang'ono.
- 4).TApa pali maluso osiyanasiyana omwe amapezeka mu mitundu ya tee, Wye, ndi angle body.

Kugwiritsa Ntchito Valavu Yokhala ndi Malo Amodzi
Valavu ya Globe ya ASMEimagwiritsidwa ntchito kwambiri m'mautumiki osiyanasiyana; onse a kuthamanga pang'ono komanso kuthamanga kwambiri kwa madzi. Ma valve ozungulira ndi awa:
- 1). Yopangidwira mapaipi okhazikika pafupipafupi, kapena kupopera madzi ndi mpweya wapakati
- 2). Madzi: Madzi, nthunzi, mpweya, mafuta osaphika ndi zinthu zopangidwa ndi mafuta, mpweya wachilengedwe, mpweya wozizira, njira zamakono, mpweya, mpweya wamadzimadzi ndi wosakwiya
- 3).Makina ozizira a madzi omwe amafuna malamulo okhudza kayendedwe ka madzi.
- 4).Makina ophikira mafuta omwe amafunikira kulimba kwa kutayikira.
- 5).Makina oyendetsera ma valve.
