Valavu yapamwamba kwambiri yolumikizira ma throttling globe yogulitsa mafakitale aku China wopanga fakitale
Kodi valavu ya throttling 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.
Valavu yolumikizira padziko lonse lapansi Ndi 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 yolumikizira padziko lonse lapansiikhoza kulamulidwa bwino ndi tsinde lopindika. Mphamvu yotsekera yaValavu yolumikizira padziko lonse lapansindi okwera kwambiri. Angagwiritsidwe ntchito pa ntchito yopuma. Chifukwa cha mtunda waufupi woyenda pakati pa malo otseguka ndi otsekedwa,Valavu yolumikizira padziko lonse lapansiNdi abwino kwambiri ngati valavu iyenera kutsegulidwa ndi kutsekedwa pafupipafupi. Chifukwa chake, mavalavu ozungulira angagwiritsidwe ntchito pa ntchito zosiyanasiyana.
aValavu yolumikizira padziko lonse lapansiingagwiritsidwenso 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.
Mbali yaikulu ya valavu ya throttling globe
- 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 throttling globe
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.
