Papiyon Valv Aplikab Okazyon

Butterfly valves are suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, the robustness of the butterfly plate to withstand the pressure of the pipeline medium should also be considered when it is closed. In addition, the operating temperature limitations of the elastomeric seat material at elevated temperatures must also be considered. The structural length and overall height of the butterfly valve are small, the opening and closing speed is fast, and it has good fluid control characteristics. The structural principle of the butterfly valve is most suitable for making large-diameter valves. When the butterfly valve is required to be used for flow control, the most important thing is to correctly select the size and type of the butterfly valve so that it can work properly and effectively.
Usually, nan throttling, reglemante kontwòl ak labou mwayen estrikti a longè yo kout ak ouvèti a ak fèmen vitès vit (1/4 vire). low pressure koupe (ti press /press /diferans)% 2c papiyon valv se rekòmande.
Butterfly tiyo itilize double-pozisyon ajisteman, etwat chanèl, bri, cavitation gasification, ti flit flit atmosfè a atmosfè a ak abrasif medya.
When throttling ajisteman obligatwa espesyal k ap travay kondisyon, oswa strik sele obligatwa, oswa mentfly valvs yo itilize grav mete, low tanperati (kriye glase) ak lòt travay kondisyon, li nesesè espesyalman ki fèt metal seal seal seal adjustment adjustment ak triple eccentricity oswa double eccentricity. butterfly valv.
Butterfly valvs yo apwopriye fresh dlo dlo, dlo dlo dlo salt 2c vapè, natirèl gaz, manje, medikaman, 2c lwil oliv types valves valves ke mande pou konplè sele zewo tès gaz tès lavi esperans, ak travay tanperati ant -10 degre ak 150 degre. Acid-base ak tiyo.
The mou-sele eccentric papiyon valv se apwopriye pou de-fason ouvèti ak fèmen ak ajisteman nan vantilasyon ak pousyè retire pipelines, ak se lajman itilize nan gaz tiyo ak dlo metallurgy, limyè endistri, electric pouvwa, petrochemical systems, elatriye.
Metal-to-metal wire sele doub eccentric papiyon valve apwopriye gaz gaz, lwil 2c asid ak alkali tiyo tankou iben chofaj 2c gaz ekipman pou, dlo ekipman pou, elatriye 2c kòm yon reglemante ak jete aparèy aparèy.
The metal-to-metal sifas-sele triple eccentric papiyon valv itilize kontwòl valv a gwo presyon balanse adsorption (PSA) gas separasyon aparèy, men dwe lajman itilize nan petroleum% 2c petrochemikal, pwodwi chimik, metallurgy, elektrik jadens. Li yon ekselan chwa pou gate valves globe valves. ranplasman pwodwi.
