3.3 – Válvulas Fluxométricas

These flashcards cover key terms and concepts related to hydraulic flow control valves as discussed in the lecture notes.

Válvulas Fluxométricas

Devices used to control the flow rate of hydraulic fluids in a system.

Caudal

The volume of fluid that passes through a section in a given amount of time.

Estrangulador

A device that restricts fluid flow in a hydraulic circuit to control speed.

Controle de Velocidade

The method of adjusting the flow of fluid to regulate the speed of hydraulic actuators.

Meter-in

A flow control method where the restriction is placed before the actuator.

Meter-out

A flow control method where the restriction is applied at the actuator's exit.

Bleed-off

A flow control method where part of the flow is diverted back to the tank.

Simbologia

Symbols used to represent different types of flow control valves in diagrams.

Válvula Direcional

A valve that controls the direction of flow in a hydraulic system.

Potência

The amount of work done per unit of time, often related to the hydraulic power of an actuator.

Viscosidade

A measure of a fluid's resistance to flow, which affects the performance of hydraulic systems.

Cilindro Hidráulico

A mechanical actuator that uses hydraulic fluid to produce linear motion.

Orifício Variável

An adjustable opening in a flow control valve that allows for variable flow rates.

Parafuso de Ajuste

A screw used to set the flow rate in a hydraulic valve.

Pressão

The force exerted by the fluid per unit area in a hydraulic system.

Relação Q versus ∆p

A relationship that describes how pressure drop corresponds to flow rate in a hydraulic circuit.
