Válvulas de mariposa doble excéntrica

What are double eccentric butterfly valves?

A Válvulas de mariposa excéntricas dobles comprises a circular disc that revolves within the valve body to either open or close the flow. En una válvula de mariposa de disco excéntrico, the disc rotates about an axis that is offset (excéntrico) from the valve body’s center. Por otro lado, a concentric butterfly valve has a disc that rotates concentrically, with the axis of rotation aligned with the centerline of the valve body and pipe. Both types are employed for flow regulation but exhibit distinct design features.

The Features Between Eccentric And Concentric Butterfly Valves

As quality double eccentric butterfly valves from China butterfly valves supplier, double eccentric butterfly valves gets many features. Sin embargo, we will compare two types of butterfly valves and list each features below:

• Eccentric disc valves have a more linear flow characteristic, maintaining consistent velocity as they open/close. This causes less turbulence.
• Concentric valves have a more progressive flow trait where flow rate increases non-linearly with valve opening. This results in more turbulence.
• By offsetting the disc, eccentric valves allowInstallation benefits in compact spaces where concentric valves can’t fit between pipe flanges.
• Sin embargo, concentric valves are simpler in design without the extra clearance required by an eccentric disc’s offset motion.

The Applications of Both Of Butterfly Valves Between Eccentric & Concentric

Como válvulas de mariposa de calidad para estos dos tipos, Ambos ven químicos anchos, petróleo/gas, fuerza, marino y más. Por instancias, En primer lugar, double eccentric butterfly valves as isolation valves to allow pipe/vessel insulation for control/drainage. En segundo lugar, double eccentric butterfly valves as control valves in piping manifolds to direct flow between multiple lines. En tercer lugar, double eccentric butterfly valves as shut-off valves in ductwork or wherever flow needs regulating in changing conditions.

Válvulas de mariposa de disco excéntrico:

• Throttling service to control flow where linearity is important such as pumping stations, HVAC systems and processing plants.
• Where space is constrained due to pipe centrelines being too close together to fit a concentric valve.

Válvulas de mariposa concéntricas:

• On/off applications where gradual filling/emptying is less critical such as ballast tanks or surge tanks.
• Where low cost is a priority due to simpler concentric design requiring less precision/clearance.
• Large water transmission mains where turbulence has minimal effect due to large pipe diameter-to-flow ratio.
