Valavu yapamwamba kwambiri ya Industrial Y globe valavu yogulitsa fakitale yaku China
Kodi valavu ya mtundu wa Y ndi chiyani?
Valavu ya mtundu wa Y,Nthawi zambiri imapangidwa ndikupangidwa motsatira muyezo wa Germany ndi muyezo wa ku Europe EN13709. Monga mwachizolowezi, valavu yake yotseka yoyenda molunjika imagwiritsidwa ntchito kuyambitsa, kuyimitsa kapena kuwongolera kuyenda kwa madzi pogwiritsa ntchito chotchinga chotchedwa disc.Valavu ya mtundu wa YNdi abwino kwambiri ndipo amagwiritsidwa ntchito kwambiri poletsa 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.
Ma bellow amakhala ndi nthawi yochepa yogwirira ntchito, zomwe zikutanthauza kuti kuthekera kwa kuphulika kungakhalepo. Ichi ndichifukwa chake cholumikizira chachizolowezi cholongedza nthawi zonse chimaphatikizidwa mu bonnet yokhala ndi bellow. Chifukwa chake chisindikizo cha bellow ndi chowonjezera cholongedza ma valve a chipata, ndi choyenera pamavuto ena ogwirira ntchito.
nthawi zambiri pamakhala mapangidwe atatu akuluakulu a thupi kapena mapangidwe aValavu ya mtundu wa Y:
- 1). Chitsanzo Chokhazikika (komanso monga 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)
Zinthu zazikulu za valavu ya mtundu wa Y globe?
Makamaka njira zamakemikolo, madzi omwe ali m'mapaipi nthawi zambiri amakhala oopsa, owopsa komanso owopsa.Ma valve a globe otsekereza a Bellowsamagwiritsidwa ntchito poletsa kutuluka kwa mankhwala aliwonse oopsa mumlengalenga. Zinthu za thupi zimatha kusankhidwa kuchokera kuzinthu zonse zomwe zilipo, Pansi pake pakhoza kuperekedwa muzinthu zosiyanasiyana monga 316Ti, 321, C276 kapena Alloy 625.
- 1). Pali mitundu yosiyanasiyana ya luso monga momwe imapezeka mu mawonekedwe wamba (mawonekedwe olimba), mawonekedwe a ngodya, ndi mawonekedwe a Wye (mawonekedwe a Y).
- 2). Mivi yachitsulo imatseka tsinde loyenda ndipo imawonjezera kulimba kwa ma valve otsekera tsinde odzaza.
- 3).Zisindikizo ziwiri zachiwiri za tsinde: a) Mpando wakumbuyo uli pamalo otseguka; b) Kupaka Graphite.
- 4). Ma valve otsekedwa ndi bellow nthawi zambiri amayesedwa kutuluka kwa madzi pogwiritsa ntchito mass spectrometer kuti azindikire kuchuluka kwa kutuluka kwa madzi pansi pa 1x10E-06 std.cc/sec. Kapangidwe kawiri kotseka (bellows seal ndi stem packing) ngati bellows yalephera, valve stem packing idzapewanso kutuluka kwa madzi, komanso mogwirizana ndi miyezo yapadziko lonse lapansi yolimba;
