Valavu Yapamwamba Yapamwamba Yapaintaneti ya API602 Yopanga Chitsulo Choyimitsa Globe Fakitale yaku China
Kodi valve ya API602 globe ndi chiyani?
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.
aValavu ya Globalbe ya API602ingagwiritsidwenso 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 valve, komanso kupereka njira yokhazikitsira makhalidwe enaake a valavu. Itha kusinthidwa mosavuta posintha magawo odulira kuti asinthe mawonekedwe a flow 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)
Mfundo Yogwirira Ntchito yaValavu ya Globalbe ya API602
Valavu yozungulira imakhala ndi diski yosunthika ndi mpando wozungulira wosasuntha m'thupi lozungulira. Mpando wa valavu yozungulira uli pakati ndipo umagwirizana ndi chitoliro, ndipo malo otseguka pampandowo amatsekedwa ndi diskiyo. Pamene gudumu lamanja likuzunguliridwa ndi manja kapena ndi actuator, kuyenda kwa diski kumayendetsedwa (kutsitsidwa kapena kukwezedwa) pogwiritsa ntchito tsinde la valavu. Pamene diski yozungulira ya valavu ikukhala pamwamba pa mphete ya mpando, kuyenda kumayima kwathunthu.
Mbali yaikulu ya API602 globe valve
- 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).Mphamvu yochepetsera thupi pang'ono mpaka yabwino, posintha kapangidwe ka mpando ndi diski.
- 4).BChisindikizo cha ellows chikupezeka ngati mupempha.
