Valavu ya chipata cha mpando wa rabara ku China Yogulitsa Zonse Wogulitsa fakitale ku China
Kodi valavu ya chipata cha mpando wa rabara ndi chiyani?
Valavu ya chipata cha mpando wa mphira,mfundo yopangira yomwe imakonda kugwiritsidwa ntchito m'magawo ogawa.
TheValavu ya chipata cha mpando wa mphiraIli ndi wedge yophimbidwa bwino ndi rabara ya EPDM yomwe imalumikizidwa kosatha ku wedge ndipo imakumana ndi ASTM D249. Thupi la valavu, bonnet, ndi mbale yodzaza zinthu zimakutidwa ndi epoxy yolumikizidwa (FBE), yokongola komanso yoteteza bwino kwambiri. Makonzedwe ena osankha amakhalanso ndi Non-Rising Stem (NRS) kapena Outside Screw & Yoke (OS&Y).
Valavu ya chipata cha mpando wa mphiraIkhozanso kugwiritsidwa ntchito ndi Spur kapena Bevel Gear, komanso actuator yamagetsi.
Zinthu zazikulu za NORTECHValavu ya chipata cha Rubber seat
Thupi imapangidwa ndi chitsulo chosungunuka pogwiritsa ntchito njira yopangira zinthu molunjika,Inapangidwa ndi mapulogalamu a 3D, yokhala ndi kusanthula kwa zinthu zochepa za kapangidwe kake. Chofunikira chachitetezo ndi choposa 2.5. Njira yosalala pansi idapangidwa, kuti ipewe kusonkhanitsa zinyalala ndikuwonetsetsa kuti madzi akuyenda bwino.
TsindeAmapangidwa ndi chitsulo chosapanga dzimbiri pozungulira. Mtundu wophatikizana, kupewa kugwiritsa ntchito mphete za mkuwa kuti muchepetse kukula kwa tsinde. Chokulungira chosalala chosinthidwa cha makwerero chimakhala chotuluka. Kupukuta kwagalasi lapadziko lonse, kumakwanira bwino mphete za O, kuti zitsimikizire kuti kuzungulira kosalala ndi mphamvu yaying'ono.
Chimango champheroChopangidwa ndi chitsulo chosungunuka pogwiritsa ntchito mchenga wophimbidwa kale, wedge imaphimbidwa ndi EPDM kwathunthu. Kapangidwe ka chisindikizo kawiri, mzere uliwonse wosindikizira ukhoza kugwira ntchito pawokha
Mabotolo a giredi 8.8 amalumikizabonetiNdipo thupi, mabotolowo anali ataphimbidwa ndi sera yosungunuka bwino yomwe imateteza mabotolowo kuti asawonongeke. Gasket pakati pa bonnet ndi thupi imapangidwa ndi EPDM. Chophimba cha valavu chimapangidwa ndi chosungira, onetsetsani kuti gasket ya rabara siituluka pansi pa madzi ambiri.
Kupanga zinthu zosamalira chilengedwe
Pamwamba ndi panja pa valavu pali ufa wa epoxy wothira ndi epoxy yolumikizidwa (FBE), makulidwe ake ndi opitilira 250um. Kumatirira kwa chophimbacho ndi kolimba, sikungawonongeke ndi mayeso a mphamvu ya 3J. Ziwalo zamkati zimatha kukwaniritsa zofunikira zoteteza chilengedwe, ndipo zitha kugwiritsidwa ntchito m'malo opezeka madzi, chakudya ndi mankhwala mwachindunji. Njira yomatira ufa wa electrostatic ingakupatseni mphamvu yomatira komanso kukana dzimbiri mwamphamvu.
Kukhazikitsa kosavuta ndi ntchito
Timapereka mitundu yosiyanasiyana ya mawonekedwe monga kulumikizana kwa flange, soketi ya PVC pipe, soketi yachitsulo ya uctile iron pipe, kuchepetsa ndi zina zotero. Kapangidwe kapadera kolumikizira kamatha kusinthidwa malinga ndi zomwe mukufuna.
ya ogwiritsa ntchito.
Valavu imatha kutsekedwa kwathunthu ndikufikira pamalo otayikira ndi torque yaying'ono. Torque yeniyeni yogwirira ntchito ndi 80% yokha ya mainchesi, ndipo ma valve a chipata amatha kunyamula MST ya 3 * DN NM. Zogulitsazo zidapambana mayeso a moyo wa nthawi 5000. Pa ma valve a mainchesi akulu, titha kupereka zida zosungira ntchito, kuti tiwonetsetse kuti ma valve onse akhoza kutsegulidwa ndikutsekedwa ndi munthu m'modzi. Gudumu lamanja ndi lamphamvu, lokhala ndi miyeso yolondola, limagwirizana bwino ndi tsinde la valavu, mawonekedwe ake ndi ogwirizana ndi makina a anthu, kuti zitsimikizire kuti ntchito yake ndi yosavuta.
Kukonza kosavuta
Mphete yotsekera ikhoza kusinthidwa popanda kudula madzi, ndikosavuta kukonza ndipo kumachepetsa nthawi yokonza momwe zingathere. Kukangana kochepa kwambiri pakati pa bushing ya mkuwa ndi chisindikizo cha mtundu wa "O", kudzaonetsetsa kuti mphete yotsekerayo ikhale ndi moyo wautali. Mphamvu yayikulu yogwirira ntchito imayendetsedwa.
