Valavu Yotsekeredwa ya Bonnet Gate
✧ Kufotokozera kwa Valavu ya Chipata cha Bonnet Yotsekedwa ndi Pressure Sealed
Valavu Yotsekeredwa ya Bonnet GateNdi valavu ya chipata yopangidwira malo okhala ndi kuthamanga kwambiri komanso kutentha kwambiri. Kapangidwe kake ka chivundikiro chotsekera kupanikizika kangathandize kuonetsetsa kuti kutsekera kukugwira ntchito bwino pakakhala zovuta kwambiri. Nthawi yomweyo, valavuyo imagwiritsa ntchito Butt Welded End Connection, yomwe imatha kukulitsa mphamvu yolumikizira pakati pa valavu ndi dongosolo la mapaipi ndikukweza kukhazikika ndi kutseka kwa dongosolo lonse.
✧ Wopereka ma valve a chipata cha Pressure Sealed Bonnet Gate Valve apamwamba kwambiri
NSW ndi kampani yodziwika bwino yopanga ma valve a mpira wa mafakitale yomwe ili ndi satifiketi ya ISO9001. Valve ya API 600 Wedge Gate Valve Bolted Bonnet yopangidwa ndi kampani yathu ili ndi kutseka kolimba komanso mphamvu yopepuka. Fakitale yathu ili ndi mizere ingapo yopangira, yokhala ndi antchito odziwa bwino ntchito yokonza zinthu, ma valve athu adapangidwa mosamala, mogwirizana ndi miyezo ya API 600. Valveyi ili ndi zida zotsekera zoletsa kuphulika, zoletsa kusinthasintha komanso zosagwira moto kuti zisawononge ngozi ndikuwonjezera nthawi yogwira ntchito.

✧ Mbali za Valavu ya Chipata cha Pressure Sealed Bonnet
Kupanikizika kwambiri komanso kutentha kwambiri
- Zipangizo za valavu ndi kapangidwe kake zaganiziridwa mwapadera kuti zigwirizane ndi momwe ntchito ikuyendera pansi pa kupanikizika kwakukulu komanso kutentha kwambiri.
- Imatha kugwira ntchito mokhazikika pansi pa milingo yokwera kwambiri monga Class 900LB, 1500LB, ndi 2500LB.
Kugwira ntchito bwino kwambiri posindikiza
- Kapangidwe ka chivundikiro chotsekera kupanikizika kamatsimikizira kuti valavu ikhoza kusungabe kutsekera kolimba pansi pa kupanikizika kwakukulu.
- Kapangidwe ka pamwamba pa kutseka kwachitsulo kamathandizanso kuti valavu izigwira ntchito bwino.
Kudalirika kwa kulumikizana kwa matako olumikizira kumapeto
- Njira yolumikizira matako imagwiritsidwa ntchito popanga kapangidwe kolimba kogwirizana pakati pa valavu ndi dongosolo la mapaipi.
- Njira yolumikizira iyi imachepetsa chiopsezo cha kutayikira kwa madzi ndipo imakulitsa mphamvu ndi kukhazikika kwa dongosolo lonse.
Kukana dzimbiri ndi kuvala
- Vavuyi imapangidwa ndi zinthu zosagwira dzimbiri komanso zosatha ntchito mkati ndi kunja kuti ipititse patsogolo moyo wa ntchito komanso kudalirika kwa vavuyi.
Kapangidwe kakang'ono komanso kukonza kosavuta
- Valavuyi ndi yaying'ono ndipo imatenga malo ochepa, zomwe ndi zosavuta kuyiyika ndi kukonza m'malo ochepa.
- Kapangidwe ka chisindikizo n'kosavuta kuyang'ana ndikusintha, zomwe zimachepetsa ndalama zokonzera ndi nthawi.
Fomu yolumikizira thupi la valavu ndi chivundikiro cha valavu
Kulumikizana pakati pa thupi la valavu ndi chivundikiro cha valavu kumagwiritsa ntchito mtundu wodzitsekera wodzikakamiza. Kupanikizika kwakukulu m'bowo, kumakhala bwino kwambiri.
Chivundikiro cha valavu chapakati pa gasket
Valavu yotsekeredwa ndi pressure sealed bonnet gate imagwiritsa ntchito pressure sealing steel ring.
dongosolo lodzaza ndi masika lodzaza ndi ma pompopompo
Ngati kasitomala apempha, njira yolumikizira yodzaza ndi masika ingagwiritsidwe ntchito kuti iwonjezere kulimba ndi kudalirika kwa chisindikizo cholumikizira.
Kapangidwe ka tsinde
Imapangidwa pogwiritsa ntchito njira yopangira zinthu, ndipo kukula kwake kochepa kumatsimikiziridwa malinga ndi zofunikira. Tsinde la valavu ndi mbale ya chipata zimalumikizidwa mu kapangidwe kofanana ndi T. Mphamvu ya pamwamba pa tsinde la valavu ndi yayikulu kuposa mphamvu ya gawo lokhala ndi ulusi wofanana ndi T la tsinde la valavu. Kuyesa mphamvu kumachitika motsatira API591.
✧ Zochitika pakugwiritsa ntchito
Mtundu uwu wa valavu umagwiritsidwa ntchito kwambiri m'mafakitale otentha kwambiri komanso opanikizika kwambiri monga mafuta, mankhwala, magetsi, ndi zitsulo. Nthawi zina, valavu imafunika kupirira kutentha kwambiri komanso kupanikizika kwakukulu pamene ikuonetsetsa kuti palibe kutuluka kwa madzi komanso kugwira ntchito bwino. Mwachitsanzo, pochotsa ndi kukonza mafuta, mavalavu a pachipata omwe amatha kupirira kutentha kwambiri komanso kupanikizika kwakukulu amafunika kuti azitha kuyendetsa mafuta ndi gasi; popanga mankhwala, mavalavu a pachipata omwe sagonjetsedwa ndi dzimbiri komanso kuwonongeka amafunika kuti atsimikizire kuti njira yopangira zinthu ndi yokhazikika komanso yotetezeka.
✧ Kusamalira ndi kusamalira
Pofuna kuonetsetsa kuti valavu ya Pressure Sealed Bonnet Gate Valve ikugwira ntchito bwino kwa nthawi yayitali, ndikofunikira kuisamalira nthawi zonse. Izi zikuphatikizapo:
1. Yang'anani nthawi zonse momwe valavu imagwirira ntchito, kusinthasintha kwa tsinde la valavu ndi njira yotumizira, komanso ngati zomangirazo ndi zotayirira.
2. Tsukani dothi ndi zinyalala mkati mwa valavu kuti muwonetsetse kuti valavu ikugwira ntchito bwino.
3. Pakani mafuta nthawi zonse ku ziwalo zomwe zimafunikira mafuta kuti muchepetse kuwonongeka ndi kukangana.
4. Ngati chisindikizocho chapezeka kuti chawonongeka kapena chawonongeka, chiyenera kusinthidwa nthawi yake kuti chitsimikizire kuti valavuyo ikugwira ntchito bwino.
