Viav vias sceck li qub yog siv dav hauv cov qauv hauv qab no vim yog lawv cov kab ke yooj yim (DNMM thiab hloov pauv / kab rov tav / nplooj.
1. Kev lag luam roj av thiab kev lag luam chemical
Cov roj av roj av ntas: tiv thaiv nruab nrab nraub qaum thaum lub taub nruab nrab thaum lub tsheb thauj mus los thiab ua rau cov khaub ncaws puas lossis ua kom muaj kev sib xyaw.
Refining thiab cia tank system: kom muaj unidirectional ntws ntawm nruab nrab hauv reactor inlet thiab qhov hluav taws xob thauj khoom thiab siv hluav taws xob thiab cov roj ntsha kom ntseeg tau tias cov txheej txheem kev nyab xeeb.
Corrosive nruab nrab tswj: lub valve lub cev ua los ntawm cov khoom siv corrosion-resistant cov ntaub ntawv xws li 304 thiab 316 (xws li cov xov tooj hluav taws xob hauv nruab nrab xws li kua qaub thiab alkali.
2. Fais thiab Zog Hluav Taws Xob
Boiler Pub Dej System: Tiv thaiv cov dej siab backflow los ntawm kev ua kom dej tso kua dej.
Chav Turbine Circuit Circuitate: Nco ntsoov Unidirectional Flow ntawm Chav kom tsis txhob condensate backflow thiab cuam tshuam rau cov khoom siv thaum kaw.
Cua txias dej ncig ua haujlwm: siv nyob rau hauv txias ntauwd Pipelines ntawm Thermal fais fab nroj tsuag kom tswj cov dej txias.
3. Kev ua nroog dej thiab ib puag ncig engineering
Nroog Muab Dej Cooth: Tiv Thaiv Txo Dej Ncua Khaub Ncaws thiab paug cov khoom hloov pauv los ntawm kev hloov pauv hauv lub network (zam kev lim dej hauv lub network (zam kev lim dej).
Dej phwj cog: ntsia ntawm lub twj tso kua mis kom tiv thaiv cov dej phwj tuaj thiab tiv thaiv kev nyab xeeb ntawm cov pawg twj tso kua mis (xws li H44H-10C-10 valve).
Kev tswj hwm dej: Tswj cov kev taw qhia ntws hauv cov dej ncig ntawm cov dej pipelines ntawm cov tshuaj, papermaking thiab lwm yam lag luam.
4. Kev tua hluav taws thiab HVAC teb
Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob: Nkag mus nrawm nrawm ntawm cov dej thaum lub twj tso kua mis nres, feem ntau siv nrog dej rauj tshem tawm (siab tuaj yeem ncav cuag 42mpa).
HVAC system: Siv rau cov kav dej kub los tiv thaiv kev sib xyaw ntawm cov dej txias thiab dej kub thiab ua rau muaj kev txuag hluav taws xob kom txo qis.
5. Lub nkoj xa khoom thiab hnyav
Lub nkoj fais fab: tiv thaiv nruab nrab rablflow hauv cov roj mov, cua txias thiab cov raj xa dej hydraulic.
Metallurgy thiab kev tsim khoom: moj tej tawg sov ua kom sov dej, hydraulic raj thiab lwm yam scenes, nrog rau kev kub siab (-196℃~ 800 degree).
◆ Daim ntawv thov cov kev txwv thiab kev ceev faj
Inapplicable stratarios: Dej Pipelines muaj cov khoom seem (yooj yim los hnav cov chaw sib khi), yooj yim los ua kom yooj yim (yooj yim rau ua kom yooj yim) kev co).
Kev tiv thaiv qis-siab txhim kho kev txhim kho: ib qho kev siv springs lossis hnyav hammer cov qauv yuav tsum tau muab ntsia txhawm rau txhim kho kev sib khi.
◆Summary : Swing check valves are key protective components for systems such as petroleum, electricity, municipal administration, and fire protection. They are automatically opened and closed through hinged valve discs. Their large-caliber advantages (such as multi-disc design with DN>600 hli) yog tsim nyog tshwj xeeb rau kev xav tau los tiv thaiv backflow hauv cov raj xa dej loj.
