Valavu ya Globe ya Bellow Seal vs Valavu ya Globe

Mu dziko lovuta la kasamalidwe ka madzi, makamaka m'magawo monga uinjiniya wa m'madzi, kukonza mankhwala, ndi kupanga magetsi, kusankha valavu yoyenera kungakhudze kwambiri osati kungogwira ntchito bwino komanso chitetezo komanso kutsatira malamulo a chilengedwe. Pakati pa mavalavu ambiri a mafakitale omwe alipo,valavu yapadziko lonsendivalavu ya padziko lonse yosindikiziraPali mitundu iwiri yofunika kwambiri yomwe imagwiritsidwa ntchito poyendetsa bwino mphamvu yamagetsi komanso kulamulira bwino kayendedwe ka madzi. Koma n’chiyani chimasiyanitsa mitunduyi? Ndipo ndi liti pamene zimakhala zofunika kusankha imodzi kuposa inzake?

Kumvetsetsa Valavu Yoyera ya Globe

A valavu yapadziko lonseNdi valavu yoyenda yolunjika yomwe idapangidwa makamaka kuti iyendetse bwino kayendedwe ka madzi. Yotchedwa dzina lake lofanana ndi thupi lake lozungulira, ili ndi diski yomwe imayenda molunjika pampando, zomwe zimathandiza kuti ikhale yolimba bwino. Chifukwa cha kudalirika kwawo komanso mtengo wake wocheperako, mavalavu ozungulira amagwiritsidwa ntchito kwambiri m'makina operekera madzi a boiler, mabwalo oziziritsira madzi, ndi makina opaka mafuta.

Zinthu Zofunika Kwambiri

• 1. Yopangidwira kuyatsa/kutseka ndi kusintha kwa kayendedwe ka madzi

• 2. Kutseka pang'ono

• 3. Yabwino kwambiri pakugwiritsa ntchito madzi osawononga

• 4. Yosavuta kusamalira komanso yopezeka paliponse

Komabe, vuto limodzi likupitirirabe: kutuluka kwa madzi osungiramo zinthu pakapita nthawi. Mu nyengo ya kupanikizika kwambiri kapena kutentha kwambiri, mafuta osungiramo zinthu ozungulira tsinde la valavu amatha kuwonongeka, zomwe zimapangitsa kuti zinthuzo zituluke—zomwe zingabweretse mavuto pa chitetezo ndi chilengedwe.

Kodi n’chiyani chimapangitsa ma valve a Bellow Seal Globe kukhala osiyana?

A valavu ya padziko lonse yosindikiziraimagwiritsa ntchito mfundo yofanana ndi ya globe valve koma imabweretsa kusintha kosintha masewera: amabelu achitsulochotchingira cholumikizidwa ku tsinde la valavu ndi boneti. Kapangidwe kameneka kamapangachisindikizo chotenthetsera, kuchotsa kuthekera kulikonse kwa kutuluka kwa madzi m'tsinde—chinthu chofunikira kwambiri papoizoni, mphamvu ya radioactivekapenayoyakamapulogalamu.

Ubwino Waukulu

• 1. Kutaya madzi kuchokera ku tsinde kulibe—kwabwino kwambiri pa zinthu zoopsa monga ammonia, haidrojeni, kapena ma asidi

• 2. Nthawi yogwira ntchito yayitali komanso yosakonza kwambiri

• 3. Imagwirizana ndi miyezo ya ISO 15848 yokhudzana ndi mpweya woipa

• 4. Amachepetsa nthawi yogwira ntchito komanso amalimbitsa umphumphu wa dongosolo

Chifukwa Chake Kusankha N'kofunika kwaMapulogalamu a panyanja

M'malo okhala m'nyanja, ma valve nthawi zonse amakhala ndi madzi amchere, kugwedezeka, komanso kutentha kwambiri. Kutayikira kulikonse—makamaka m'mafuta, m'madzi ozizira, kapena m'makina oletsa moto—kungayambitse zotsatira zoopsa kwambiri.

Ma valve okhazikika a globe akadali ofala m'magwiritsidwe ntchito osafunikira kwenikweni, koma ma valve ozungulira a bellow seal akukhala chisankho chomwe chimakonda kwambiri pa: Mizere yamafuta ya chipinda cha injini, makina amadzi a Ballast, kugwiritsa ntchito nthunzi yotentha kwambiri komanso mapaipi a mankhwala a Cargo
