Hom Npauj Npaim Valve
Muaj peb yam tseem ceeb ntawm npauj npaim li qub:
1.Zero Offset Npauj Npaim Valves (Resilient Seat Butterfly Valves)
2.Double Offset Npauj Npaim Valve (Kev Ua Haujlwm Siab Npauj Npaim Valves
3.Triple Offset Npauj Npaim Valve
Nyob rau hauv xoom offset npauj npaim li qub, lub qia dhau los ntawm qhov nruab nrab ntawm lub disc uas yog nyob rau hauv lub rooj zaum; Tag nrho cov no yog nyob rau hauv lub valve lub cev. Lub cev valve. rooj. thiab disc pw concentrically thaum nws nyob rau hauv ib qho chaw kaw.
Zero offset npauj npaim li qub yog siv nyob rau hauv liauid thiab aas pipelines. uas muaj siab thiab kub ratinas ntawm 250 psi thiab 4000F, feem.
Hauv ob qhov offset npauj npaim li qub, lub qia axis yog offset tom qab qhov nruab nrab ntawm lub rooj zaum thiab lub cev (thawj offset), tom qab ntawd
qia axis yog ntxiv offset los ntawm vertica centerline ntawm vaive (thib ob offset).Thaum lub disc qhib. lub rooj yog fted
los ntawm lub foob;
Ob chav offset npauj npaim li qub feem ntau yog siv rau hauv dej purification. Kev kho dej khib nyiab. HVAC. thiab tiv thaiv hluav taws
systems (piv txwv li, hluav taws sprinklers). Rau qhov kub thiab txias tsis kam, tus nqi ntawm cov khoom siv lub rooj zaum yog txo los ntawm kev thim rov qab nrog ib txheej hlau.
Nyob rau hauv triple offset npauj npaim li qub, lub angular offset nyob rau hauv lub cev sealing cone axis yog ua ntxiv rau thawj ob offsets (thib peb offset). Qhov no yog ua tiav los ntawm kev siv txoj cai-angled conical profile ntawm lub rooj zaum ua ke nrog qhov sib txuam profile ntawm ntug disc. Qhov offset no tshem tawm qhov kev sib cuag ntawm lub rooj zaum thiab lub disc thaum lub valve qhib thiab kaw, yog li, kev sib txhuam kuj raug tshem tawm. Kev sib cuag tsuas yog tshwm sim thaum lub sij hawm kaw tag nrho ntawm npauj npaim valve; qhov no kuj ua raws li lub tshuab nres los tiv thaiv lub disc los ntawm kev tig mus ntxiv.
Triple offset npauj npaim li qub yog qhov zoo tagnrho hauv kev tuav cov cua kub siab thiab superheated chav, cov kua dej kub thiab
gases, thiab cov tshuaj corrosive uas tsis tuaj yeem ua los ntawm npauj npaim li qub nrog cov rooj zaum muag. Cov li qub no feem ntau siv rau hauv cov chaw tsim hluav taws xob (xws li rau-thiab-tawm li qub rau boilers), ua cov roj thiab roj. chemical manufacturing, pulp thiab paper manufacturing, thiab offshore pipelines.
