Valavu ya Gulugufe Yachiwiri Yokhala ndi Mphira
Kodi ma valve awiri a gulugufe owoneka bwino ndi chiyani?
Valavu ya Gulugufe Yachiwiri Yozungulirandi chinthu chatsopano chopangidwa ndi kapangidwe ka double offset chokhala ndi ukadaulo wapamwamba kwambiri padziko lonse lapansi. Valavu ya gulugufe iyi ili ndi kapangidwe kake kapadera kokhala ndi magwiridwe antchito odalirika kwambiri, magwiridwe antchito ambiri komanso mphamvu yochepa yogwirira ntchito.
Mphete yotsekera ya valavu ya gulugufe iwiri yopangidwa ndi elastomer yokwanira mu disc, imapezeka kuti igwiritsidwe ntchito potsekera mbali imodzi, imagwiritsidwa ntchito kwambiri m'madzi kapena m'madzi am'deralo.
Chomwe chimasiyanitsa ndi ma valve ena onse a gulugufe, ndi kapangidwe ka ma disc awiriawiri kapena awiriawiri.
Zimalola kuti diski isunthe kuchoka pampando, zomwe zimachepetsa mphamvu yothamanga komanso kuwonongeka kwa mipando, ndi mwayi waukulu poyerekeza ndi ma valve a gulugufe ozungulira.
Ma valve awiri a gulugufe osakanikirana, okhala ndi mphete yosindikizira yokhazikika ndi chivundikiro, Izi zimapangitsa kuti valavu ikhale ndi malo okhazikika okhazikika pabwalo ndikupangitsa kuti valavu isakhudze mpando wonse ikatsegulidwa kwathunthu. Kapangidwe kameneka kapangitsa kuti mpando usamakumane ndi kukangana pang'ono ndipo motero udzawonjezera nthawi yake yonse. Pogwiritsidwa ntchito nthawi zambiri, valavu ya gulugufe iyi yolunjika mbali zonse ziwiri imangokhala ya gulu 150.
Zinthu zazikulu za mavavu awiri a gulugufe a NORTECH okhala ndi mphira wokhala ndi eccentric?

CHIFUKWA CHIYANI CHOSANKHA IFE?
Qkutumiza kwa uick, kokonzeka kutumizidwa kwa milungu 1-4, ndi ma valve a gulugufe okhala ndi mphamvu komanso zinthu zina zofunika.
Qchitsimikizo cha utility cha miyezi 12-24 cha ma valve a gulugufe okhala olimba
Qkuwongolera bwino gawo lililonse la valavu ya gulugufe
Zinthu zazikulu za Ma valve awiri a gulugufe okhazikika:
Moyo wautali wautumiki chifukwa cha diski yokhotakhota
Kupsinjika kwa diski kumatulutsidwa pambuyo potseguka pang'ono zomwe zimachepetsa kuwonongeka kwa chisindikizo cha diski. Kuphatikiza apo, kapangidwe kake kamachepetsa kupsinjika kwa kutseka komwe kumatsimikizira kuti ma torque ogwirira ntchito ndi ochepa.
Mapangidwe a mipando iwiri
Kapangidwe ka mpando wophatikizana uli ndi mpando wachitsulo wopangidwa ndi makina komanso wokutidwa ndi epoxy womwe uli mkati mwake. Kapangidwe ka mpando wachitsulo chosapanga dzimbiri uli ndi mphete ya mpando yosinthidwa yachitsulo chosapanga dzimbiri yotsekedwa ndi mphete ya O kuti isatuluke pansi pa mphete ya mpando.
Mapangidwe a shaft
Kutseka kwa shaft kumatha kusinthidwa mukapanikizika kuti kukhale kosavuta kukonza. Kutseka kwa EPDM kumateteza kulimba mkati ndi kunja, ndipo kutseka kwa NBR kumateteza ku zinyalala ndi madzi ochokera kunja.
Chisindikizo cha diski chokonzedwa bwino kuti chigwire ntchito bwino
Chisindikizo cha disc chimapangidwa kuti chikhale cholimba pamalo oyenera, zomwe zimapangitsa kuti chikhale chodalirika kwambiri. Ubwino wa rabala wabwino kwambiri umapangitsa kuti zitheke kuchepetsa kuchuluka kwa rabala zomwe zimapangitsa kuti ma torque otsekeka azikhala ochepa. Kutseka kwa EPDM kwavomerezedwa ndi ACS ndi WRAS.
Kulimba kwa mbali ziwiri
Ma valve ndi a mbali ziwiri ndipo a mbali imodzi akafuna.
Chisindikizo chosinthika pa diski ndi chokhazikika
Kapangidwe ka Ddouble offset kamapangitsa kuti mipando isawonongeke kwambiri komanso kuti mphamvu ya mipando ikhale yochepa.
Kukangana kochepa kumatsimikizira kuti ntchitoyo ikhala nthawi yayitali
