Valavu Yokhazikika Yopanda Tsinde Lokwera DIN3352-F4 fakitale yaku China
Kodi Valavu ya Chipata Chosakwera ndi Chiyani?
Valavu Yopanda Chipata Chokwera,mfundo yopangira yomwe imakonda kugwiritsidwa ntchito m'magawo ogawa.
Valavu ya Non Rising Stem Gate ili 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.
Valavu Yopanda Chipata Chokwera ndi yotchuka kwambiri pa ntchito zamafakitale.
- 1) Kusindikiza kwangwiro: kusindikiza kwa thovu kolunjika mbali zonse ziwiri.
- 2) Mtengo wotsika: mpando wa rabara umaphwanyidwa pa wedge, palibe chifukwa chowonjezera kukonza mpando wa valavu.
- 3) Kapangidwe kosavuta komanso kukonza kosavuta
Zinthu zazikulu za NORTECHNon Rising Stem Gate Valve
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.
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
Zigawo za rabara zimapangidwa ndi EPDM kapena NBR yapamwamba kwambiri, zomwe zikugwirizana ndi zofunikira za madzi akumwa, kupewa vuto la rabara wamba lomwe lingayambitse tizilombo toyambitsa matenda. Zogulitsazi sizingovomerezedwa ndi miyezo ya dziko la China yokhudzana ndi madzi akumwa, komanso zavomerezedwa ndi WRAS ku UK ndi ACS ku France. Mtedza wa tsinde umapangidwa ndikuzunguliridwa kuchokera ku ndodo ya mkuwa ya dziko lonse (yochepa), ndipo palibe kuipitsidwa kwa madzi.
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.
