Vavu ya chipata cha mpeni imatha kugawidwa m'mitundu itatu molingana ndi njira yolumikizirana, kulumikizana kwa matako, kulumikizana kwa flange ndi kulumikizana kwa lug.Malinga ndi kukula kwa chipata cha mpeni valavu, kuthamanga kwapakati kumachokera ku PN16-PN2., Mavavu a mpeni amagwiritsidwa ntchito kwambiri popanga mapepala, mankhwala a fiber, petrochemical, metallurgy, matope, magetsi, madzi amadzimadzi.Pazamankhwala ndi zina zogwirira ntchito, valavu ya chipata cha mpeni imapangidwa makamaka ndi thupi la valve ndi chipata.Zida za thupi la valve ndi chitsulo cha ductile, chitsulo cha carbon ndi chitsulo chosapanga dzimbiri, ndipo malo osindikizira amapangidwa ndi mphira wachilengedwe wosamva kuvala, mphira wa fluorine, mphira wa nitrile, ndi mphira wa EPDM.Ndipo kusindikiza zitsulo, kuchokera kumalo owonetserako, valavu ya chipata cha mpeni imakhala ndi mapangidwe ang'onoang'ono, imatenga malo ochepa, ndipo imatha kuthandizira mphamvu ya payipi.
Knife Gate Valve imagwiritsidwa ntchito pamapaipi akumafakitale kuti azigwira ntchito pozimitsa.Maonekedwe a thupi ndi mpando amathetsa kutsekeka kwa shutoff kwa kuyenda ndi tinthu tating'ono.Komanso, beveled mpeni m'mphepete kumathandiza .. chipata kudula mwa wandiweyani TV mosavuta.Malinga ndi zochitika zosiyanasiyana zogwirira ntchito: valavu yosakwera tsinde la mpeni, mpeni wophika
valavu yachipata, valavu yachipata cha mpeni, valavu ya chipata cha mpeni, valavu yachipata cha mpeni wamagetsi, valavu yachipata cha mpeni ndi bevel
gear mpeni chipata vavu zonse zilipo.
Mawonekedwe:
1. Thupi:
a) Thupi lophatikizika lomwe lili ndi mawonekedwe athunthu limapangitsa kuyenda bwino, kusonkhana kosavuta komanso kutha kwa zipolopolo zazing'ono.
b) Kapangidwe ka zikhadabo zowongolera pansi pa doko poika zipata, m'malo mwa poyambira, zimachotsa kutsekeka kulikonse komwe valavu yatsekedwa.
2. Chipata:
a) Beveled mpeni m'mphepete amapereka kupsinjika kwamphamvu kudula komanso kusindikiza kolimba.
b) PTFE resilient point guider pamwamba pa doko imalepheretsa kukhudzana kwachitsulo pakati pa chipata ndi thupi.
c) Makulidwe a zipata atha kuonjezedwa kuti akwaniritse kukakamizidwa kwambiri.
3. Mpando:
a) Mpando wolowera m'mbali umatha kusintha, kuchepetsa mtengo wokonza.
b) Mpando wodzaza kale ndi wosinthika kuti ugwirizane ndi magulu osiyanasiyana osindikizira ndikulipiritsa mavalidwe abwinobwino.
4. Zina:
a) Kuponyedwa kawiri kumachepetsa torque yofunikira kuti igwire ntchito
Pali 3 mbali monga pansipa:
Pansi pa chipatacho ndi tsamba lakuthwa lopangidwa ndi U, lomwe limatha kupukuta zomatira pamalo osindikizira ndikudula mwachangu madziwo.wapakati
2. Pamwamba pa chipatacho chakhala chopukutidwa bwino komanso chopukutidwa, chomwe sichimangokhalira kusindikiza bwino, komanso chimateteza bwino moyo wautumiki wa mpando wonyamula ndi valve.
3. Chingwe chowongolera pa thupi la valve chimapangitsa kuti chipata chiziyenda bwino, ndipo chipika cha extrusion chimatsimikizira kuti chisindikizo chikugwira ntchito bwino.
ZFA Valve imagwira mosamalitsa muyezo wa API598, timayesa kukakamiza kumbali zonse za valve 100%, kutsimikizira kutulutsa ma valve 100% kwa makasitomala athu.
Thupi la valavu limatenga zinthu zamtundu wa GB, pali njira 15 kuchokera kuchitsulo kupita ku valavu.
Kuyang'ana kwaubwino kuchokera ku chopanda kanthu kupita kuzinthu zomalizidwa ndikutsimikizika 100%.
ZFA Valve imayang'ana kwambiri kupanga mavavu kwa zaka 17, ndi gulu la akatswiri opanga, titha kuthandiza makasitomala athu kusungitsa zolinga zanu ndi khalidwe lathu lokhazikika.
