A Valavu ya Nthunzi Yotentha, yomwe imadziwikanso kutiValavu Yophimba Bellows Seal Globe, ndi valavu yamafakitale yopangidwa kuti izimitse, kufalitsa, ndikuwongolera kuyenda kwa sing'anga poika mphamvu kudzera mu tsinde la valavu kuti ipange chisindikizo cholimba pakati pa diski ndi mpando. Ndi gawo lofunikira kwambiri lowongolera lomwe limagwiritsidwa ntchito makamaka m'mapaipi a nthunzi otentha kwambiri m'mafakitale monga mafuta ndi gasi, mankhwala, kupanga magetsi, ndi zitsulo.
Kumvetsetsa Valavu ya Steam Globe ndi Udindo Wake Wofunika Kwambiri
Vavu iyi ili ndi bellows ziwiri zolumikizidwa ku kapangidwe ka tsinde, zomwe zimapangitsa kuti tsinde lisatuluke. Kapangidwe kake kamakonza malo a mpando ndi njira yamphamvu, zomwe zimathandiza kuti mphamvu yapakati igwire ntchito potseka, zomwe zimachepetsa chiopsezo cha kutayikira. Disiki ya plug-type ili ndi malo otsekera osalala kapena ozungulira, omwe amathandizidwa ndi zomangira zotsekera zambiri monga mphete zopakira ndi kuyika kwa graphite kosinthasintha kuti ateteze kutayikira. Yopangidwa ndi zipangizo monga chitsulo cha carbon ndi chitsulo chosapanga dzimbiri, imathandizira kulumikizana kosiyanasiyana kumapeto (kokhala ndi flanged, ulusi, welded) ndi njira zoyendetsera (zamanja, zida, zopumira). Kuyika kumafuna kuonetsetsa kuti njira yapakati yoyendera ikugwirizana ndi chizindikiro cha thupi la valavu; mavavu pamapaipi akuluakulu ayenera kuyesedwa mphamvu ndi kulimba asanayikidwe.
Ntchito Yaikulu: Kuwongolera Kuyenda Kwabwino kwa Machitidwe a Nthunzi
Chiwalo chomaliza chaValavu ya Nthunzi Yotenthandi diski yooneka ngati pulagi. Malo ake otsekera ndi athyathyathya kapena ozungulira, ndipo diskiyo imayenda molunjika pakati pa madzi. Mwa kulamulira kuchuluka kwa kutseguka kwavalavu yapadziko lonse, kuwongolera molondola kuchuluka kwa nthunzi kumachitika.
Chifukwa Chake Steam Imafuna Mtundu Wapadera wa Globe Valve
Utumiki wa nthunzi umafuna ma valve olimba chifukwa cha kutentha kwambiri komanso kupanikizika. Ubwino waukulu ndi monga:
1. Kapangidwe kabwino:Kusindikiza kodalirika, magwiridwe antchito abwino kwambiri, komanso kapangidwe kake kokongola.
2. Malo Okhazikika Otsekera:Malo otsekera nthawi zambiri amakhala olimba ndi zinthu zopangidwa ndi cobalt, zomwe zimapangitsa kuti zikhale zolimba, dzimbiri, komanso kuti zisawonongeke kwa nthawi yayitali.
3. Tsinde la Valavu Yochiritsidwa:Tsinde limaphwanyidwa, kutenthedwa, komanso kutsukidwa kuti lisawonongeke ndi dzimbiri komanso kusweka.
4. Chisindikizo Chawiri:Kudalirika kowonjezereka popanda kutayikira konse, nthawi zambiri kuphatikiza bellows ndi kulongedza.
5. Chizindikiro cha Malo a Tsinde:Imapereka chizindikiro chowoneka bwino cha momwe valavu imatsegukira/kutsekera.
6. Zipangizo Zosinthika:Zigawo, flange, ndi miyeso ya weld-end zitha kusankhidwa kutengera momwe ntchito ikuyendera kuti zikwaniritse zosowa zosiyanasiyana za polojekiti.
