Valavu ya Gulugufe Yachiwiri Yopanda Kuzungulira ya Waterworks

Valavu ya gulugufe ya Nortech yozungulira kawiri yogwiritsidwa ntchito pa ntchito zamadzi imapereka kutseka kodalirika komanso kotsika kwa mphamvu pa mapaipi akuluakulu. Ma disc awiri ozungulira amachotsa kukhudzana kosalekeza kwa mipando panthawi yogwira ntchito, zomwe zimawonjezera nthawi yogwira ntchito komanso kuchepetsa mphamvu yogwirira ntchito poyerekeza ndi mapangidwe ozungulira. Ma valve awa amapezeka mu DN350–DN2000 (14″–80″), ndipo amapangidwa kuti azigwiritsidwa ntchito popereka madzi m'matauni, malo oyeretsera madzi, ndi makina akuluakulu amadzimadzi m'mafakitale.

Chitsulo chopangidwa ndi ductile ndi diski yokhala ndi mpando wa EPDM kapena NBR wosinthika zimathandizira kuti ntchito yotseka ikhale yogwira ntchito kwa nthawi yayitali komanso kuti ikhale yosavuta kukonza. Zimagwirizana ndi EN 593, API 609 ndi AWWA C504. Maso ndi maso mogwirizana ndi ANSI B16.10, ISO 5752 Series 13/14, EN 558-1 Series 13/14. Mapeto a flange mogwirizana ndi ASME B16.5, B16.47, AWWA C207, EN 1092-2. Zayesedwa mogwirizana ndi API 598. Kuyeza kwa kuthamanga PN10/16/25, ANSI Class 150.

Nortech ndi kampani yotsogola kwambiri ku China yopanga ma valve agulugufe awiri osasunthika komanso ogulitsa AWWA, yomwe imapereka chithandizo kwa makasitomala amadzi ndi mafakitale padziko lonse lapansi.

Valavu ya Gulugufe Yachiwiri Yopanda Kanthu — Tsamba la Zamalonda
Kodi valavu ya gulugufe ya Double Eccentric ndi chiyani?

Thevalavu ya gulugufe iwiri yosiyana— yomwe imadziwikanso kuti valavu ya gulugufe wa double offset — ili ndi mawonekedwe apadera a disc komwe shaft imachotsedwa pakati pa disc komanso pakati pa chitoliro. Kapangidwe ka offset kameneka kamalola disc kuchoka pampando nthawi yomweyo ikatsegulidwa, zomwe zimapangitsa kuti disc isagwirizane nthawi zonse ndi mpando panthawi yogwira ntchito.

Zotsatira zake ndi kuchepa kwa mphamvu yogwirira ntchito, kuchepa kwa mipando, komanso nthawi yayitali yogwirira ntchito poyerekeza ndi ma valve a gulugufe ozungulira. Ikatsegulidwa kwathunthu, diskiyo siikhudzana ndi mpando, zomwe zimapangitsa kuti malo otsekerawo asawonongeke kwa nthawi zambirimbiri.

Mphete yotsekera imapangidwa ndi elastomer, yoyikidwa mu diski ndikutetezedwa ndi mbale yophimba, ndikupanga malo otsekera osalekeza, osasinthasintha mozungulira kuzungulira konse. Kapangidwe kameneka kamapereka magwiridwe antchito odalirika otsekera mbali zonse ziwiri ndipo nthawi zambiri amasankhidwa kuti azigwira ntchito zamadzi m'matauni, malo oyeretsera madzi, ndi mapaipi akuluakulu.

Yoyenera kugwiritsidwa ntchito potseka mbali imodzi komanso mbali ziwiri. Kuyeza kwa kuthamanga kwa ANSI Class 150 / PN10 / PN16 / PN25.

Kapangidwe Kawiri Kosiyanasiyana— mawonekedwe a ma disc awiri otsekedwa amatanthauza kuti ma disc cams amachoka pampando atangotseguka pang'ono, zomwe zimachotsa kukangana kwa mpando panthawi yonse ya stroke ndikuwonjezera moyo wa mpando poyerekeza ndi mapangidwe ozungulira.

Zinthu zazikulu za valavu ya gulugufe iwiri yokongola
Moyo wautali wautumiki — kapangidwe ka ma disc opendekeka

Kupsinjika kwa diski kumatulutsidwa pambuyo potseguka pang'ono, zomwe zimachepetsa kuwonongeka kwa chisindikizo cha diski. Kapangidwe kake kamachepetsanso kupsinjika kwa mpando, kuonetsetsa kuti torque yogwira ntchito imakhala yochepa nthawi yonse ya ntchito ya valavu.

Mapangidwe a mipando iwiri alipo

Kapangidwe ka mpando wofunika kwambiri kamakhala ndi mpando wachitsulo wopangidwa ndi makina komanso wokutidwa ndi epoxy womwe uli mkati mwake. Kapangidwe ka mpando wachitsulo chosapanga dzimbiri kamapereka mphete ya mpando yomwe ingasinthidwe yotsekedwa ndi mphete ya O kuti isatayike pansi pa mphete ya mpando.

Kapangidwe ka shaft — kosinthika mukapanikizika

Kutseka kwa shaft kumatha kusinthidwa kwathunthu mukapanikizika, zomwe zimathandiza kuti ntchito yokonza malo ikhale yosavuta popanda kutseka chingwe. Zisindikizo za EPDM zimathandizira kuti mkati mwake mukhale olimba; Zisindikizo za NBR zimateteza ku zinyalala zakunja ndi kulowa kwa madzi.

Chisindikizo cha diski chokonzedwa bwino kuti chigwire ntchito bwino

Kukhazikika kwa chisindikizo cha disc kumatsimikizira kukhazikika koyenera komanso kugwira ntchito kodalirika. Mphira wabwino kwambiri umalola kuti chisindikizo chikhale chochepa, zomwe zimapangitsa kuti ma torque otseka azikhala ochepa. Kutseka kwa EPDM kwavomerezedwa ndi ACS ndi WRAS kuti zigwiritsidwe ntchito m'madzi akumwa.
