Valavu ya Chipata cha Bellows Seal
Kodi valavu ya chipata cha bellows seal ndi chiyani?
Valavu ya Chipata cha Bellows Sealidapangidwa kuti ikwaniritse zofunikira kwambiri pakulimba komanso mikhalidwe yovuta yogwirira ntchito.
kupatulapo msonkhano wamba wonyamula katundu monga valavu yonse ya chipata,valavu yotsekera chitseko cha bellowsilinso ndi chipangizo chopakira zinthu pansi.
Njira yosiyana kwambiri ndi kulongedza ndi chipangizo chotchedwa bellows seal, chubu chachitsulo chofanana ndi accordion chomwe chimamangiriridwa ku tsinde la valavu ndi ku bonnet, chomwe chimapanga chisindikizo chosataya madzi chomwe chili ndi kukangana kochepa ndipo chisindikizo cha bellows chimatha kutambasuka ndikukanikiza ndi mayendedwe olunjika a tsinde lotsetsereka. Popeza bellows ndi chubu chachitsulo chosasinthasintha, palibe malo oti kutuluka madzi kutuluke.
Chitseko chomwe chili pa bonnet yotambasuka chimagwira ntchito ngati malo olumikizira masensa ozindikira kutuluka kwa madzi, kuti apereke alamu ndi/kapena kuchitapo kanthu ngati bellow yaphulika. Pamene bellow seal yasweka, sensayo idzazindikira kutuluka kwa madzi ndipo gulu lokhazikika lolongedza lidzasunga chisindikizo choyenera mpaka valavu itakonzedwa.Bellows imakhala ndi nthawi yochepa yogwirira ntchito, zomwe zikutanthauza kuti kuthekera kwa kuphulika kungakhalepo. Ichi ndichifukwa chake cholumikizira chachizolowezi nthawi zonse chimaphatikizidwa mu boneti yokhala ndi bellows.
Mivi yooneka ngati accordion imakhala mkati mwa chubu chokhuthala chachitsulo.Malekezero amodzi a bellows amalumikizidwa ku tsinde la valavu, ndipo malekezero ena amalumikizidwa ku chubu choteteza. Popeza flange yayikulu ya chubuyo yalumikizidwa mwamphamvu mu boneti ya valavu, pali chisindikizo chopanda kutayikira.
Ma bellows amakhala ndi nthawi yochepa yogwirira ntchito, zomwe zikutanthauza kuti kuthekera kwa kuphulika kungakhalepo. Ichi ndichifukwa chake cholumikizira chachizolowezi nthawi zonse chimaphatikizidwa mu bonnet yokhala ndi bellows.Chisindikizo cha bellows ndi chowonjezera chomangira ma valve a chipata, ndi choyenera pamavuto ena ogwirira ntchito.
Zinthu zazikulu za valavu ya chipata chotsekedwa ndi bellows seal?
Makamaka njira zamakemikolo, madzi omwe ali m'mapaipi nthawi zambiri amakhala oopsa, owopsa komanso owopsa.Ma valve otsekera chitseko cha 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). Mivi yachitsulo imatseka tsinde loyenda ndipo imawonjezera kulimba kwa ma valve otsekera tsinde odzaza.
- 2). Khomo loyang'anira ma bellows (ngati mukufuna): Pulagi ikhoza kulumikizidwa ndi malo omwe ali pamwamba pa ma bellows kuti iwunikire momwe zinthu zikuyendera.
- 3).Zisindikizo ziwiri zachiwiri za tsinde: a) Mpando wakumbuyo uli pamalo otseguka; b) Kupaka Graphite.
- 4).Pa valavu ya chipata cha Bellows seal, zigawo zake zofunika kwambiri ndi zitsulo, malekezero apansi ndi tsinde la valavu zimakulungidwa zokha, ndipo malekezero apamwamba ndi chubu choteteza zimakulungidwa zokha. Chotchinga chachitsulo chimapangidwa pakati pa tsinde pamalo olowera kudzera mu malire a kuthamanga ndi madzi otuluka mkati mwa valavu, kuti athetse kutuluka kwa tsinde;
- 5). 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 ka kutseka kawiri (kutseka kwa bellows ndi kuyika tsinde) ngati bellows yalephera, kuyika tsinde la valve kudzapewanso kutuluka kwa madzi, komanso mogwirizana ndi miyezo yapadziko lonse lapansi yolimba;
- 6). Maboneti otsekedwa bwino amathandizidwa ndi seti yokhazikika yokonzera tsinde ndi malo owunikira kutuluka kwa madzi pakati pa mabellow ndi paketi kuti apewe kutulutsa madzi oopsa ngati mabellow atatuluka.
- 7). Sizongogwiritsidwa ntchito ngati zomangira za mafuta zachikhalidwe za ulusi wa tsinde lokha, koma nipple yamafuta imapangidwa pa bonnet ya valavu, tikhoza kudzoza mafuta pa tsinde, mtedza ndi bushing mwachindunji, kudzera mu nipple yamafuta;
- 8). Chikwama chamanja chopangidwa mwaluso, chokhala ndi nthawi yayitali yogwirira ntchito, chosavuta kugwiritsa ntchito, chotetezeka komanso chodalirika;
