Mavavu a Gulugufe Atatu ndi mavavu omwe amagwiritsa ntchito mbale ya gulugufe ya mtundu wa disc kuti azungulire 90 ° mmbuyo ndi mtsogolo kuti atsegule, kutseka kapena kusintha sing'angayo kuti asamayende bwino.The Iwo ali ndi dongosolo losavuta, voliyumu yaying'ono, kulemera kochepa, kugwiritsa ntchito zinthu zochepa, kukula kwazing'ono, torque yaing'ono yoyendetsa galimoto, ntchito yosavuta komanso yofulumira, komanso ntchito yabwino yoyendetsera kayendetsedwe kake ndi kutseka kusindikiza.Triple Offset Butterfly Valves amagwiritsidwa ntchito kwambiri muzitsulo, mphamvu yamagetsi, mafakitale a petrochemical, madzi ndi ngalande, zomangamanga zamatauni ndi mapaipi ena a mafakitale okhala ndi kutentha kwapakati ≤ 425 ℃.Amagwiritsidwa ntchito kuwongolera kutuluka ndi kudula madzimadzi.
Waukulu yomanga mbali zaMtengo wa JLPVvalavu yamagulugufe atatu ndi awa:
1. Mawonekedwe atatu a eccentric ndi njira ziwiri zosindikizira
Mzere wa tsinde la valve umachoka pakatikati pa disc ndi pakati pa thupi nthawi yomweyo, ndipo nsonga yozungulira ya mpando wa valavu imakhala ndi ngodya inayake ndi njira yozungulira thupi la valve.Chisindikizo cha chimbalecho chimangolumikizana ndi mpando wa valve pamene uli pamalo otsekedwa, zomwe zimapangitsa mpando wa valve ndi mbale ya butterfly pafupifupi kuvala.Mphamvu ya torque imapangidwa panthawi yotseka, zomwe zimapangitsa mpando wa valve kukhala ndi ntchito yosindikiza yotseka mwamphamvu.
2. Mpando wa triple offset butterfly valve ndi mpando wa thupi kapena pamwamba, womwe umapangidwa ndi zipangizo zosiyanasiyana.
Maonekedwe a mpando wa thupi la triple offset butterfly valve ndikuyika mpando pathupi.Poyerekeza ndi chimbale ndi mpando, izo zimachepetsa kwambiri mwayi mpando kulankhulana sing'anga mwachindunji, motero kuchepetsa mlingo wa kukokoloka ndi kutalikitsa moyo utumiki mpando.Njira yowonekera ya valavu ya gulugufe katatu imachitika motsatira njira yovomerezeka yowotcherera ya WPS.Pambuyo pamwamba, kutentha mankhwala, Machining, kuyeretsa bwinobwino ndi kuyendera zidzachitika kwa kuwotcherera pamwamba malinga ndi zofunika pamaso msonkhano.
3. Mapangidwe ampando osinthika
Mpando wa valve umapangidwa ndi chitsulo chosapanga dzimbiri ndi pepala la graphite.Kapangidwe kameneka kakhoza kulepheretsa kukhudzidwa kwazing'ono zolimba mkatikati ndi kusindikiza pamwamba pa chinkhoswe chifukwa cha kuwonjezereka kwa kutentha.Ngakhale patakhala kuwonongeka kochepa, sipadzakhala kutayikira.
4. Anti-flying tsinde kupanga
Kulongedza kwa tsinde sikophweka kuonongeka ndipo kusindikiza ndikodalirika.Zimakonzedwa ndi pini ya taper ya diski, ndipo mapeto owonjezera amapangidwa kuti ateteze tsinde kuphulika pamene ndodo ya valve imathyoledwa mwangozi pakugwirizanitsa ndodo ya valve ndi mbale ya butterfly.
5. Mpando: chisindikizo chofewa ndi chisindikizo cholimba
Mapangidwe a JLPV Triple Offset Butterfly Valve ali motere:
1. Kukula: 2 "mpaka 96" DN50 mpaka DN2400
2. Kupanikizika: Kalasi 150lb mpaka 900lb PN6-PN160
3. Zida: carbon steel, zitsulo zosapanga dzimbiri ndi zipangizo zina zapadera.
NACE MR 0175 anti-sulfure ndi anti-corrosion zitsulo zipangizo.
4. Kulumikizana kumatha: Flange, Wafer, Mtundu wa Lug malinga ndi ASME B 16.5
ASME B 16.25 mu matako kuwotcherera malekezero.
5. Miyezo ya nkhope ndi maso: igwirizane ndi ASME B16.10
6. Kutentha: -29 ℃ mpaka 425 ℃
Ma valve a JLPV amatha kukhala ndi zida zamagetsi, ma pneumatic actuators, ma hydraulic actuators, ma actuators amagetsi, zida zotsekera, ma chainwheel, ma tsinde otalikirapo ndi zina zambiri zilipo kuti zikwaniritse zosowa za makasitomala.
