Valavu yapamwamba kwambiri ya ASME B16.34 ya mafakitale ku China
Kodi valavu ya globe ya ASME B16.34 ndi chiyani?
Valavu ya globe ya ASME B16.34Ndi imodzi mwa mapangidwe otchuka kwambiri a ma globe valves, a US ndi API system. M'mimba mwake, zipangizo, maso ndi maso, makulidwe a khoma, kutentha kwa kuthamanga, zimatanthauzidwa ndi ASME B16.34.
Kuphatikiza apo, kutengera kapangidwe ka mpando ndi diski, katundu wokhalamoValavu ya globe ya ASME B16.34ikhoza kulamulidwa bwino ndi tsinde lopindika.
aValavu ya globe ya ASME B16.34ingagwiritsidwenso 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
Mfundo Yogwirira Ntchito oValavu ya globe ya ASME B16.34
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 valavu ya globe ya ASME B16.34
- 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.
- 5).Kukonza ndi kukonzanso mipando mosavuta, pazifukwa zosiyanasiyana.

Kugwiritsa ntchito valavu ya globe ya ASME B16.34
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.
- 6).Ma ventilator okhala ndi malo okwera komanso ma drain otsika.
- 7).Mafuta ndi Gasi, Madzi Odyetsa, chakudya cha mankhwala, Malo Oyeretsera, makina otulutsira mpweya wa condenser, ndi makina otulutsira madzi.
