Globe Valves are a type of flow control valve that is used to regulate the flow of liquids, gases, and other fluids. It consists of a round, circular body with a movable plug that can be opened and closed to control the flow of fluid through the valve. The working mechanism of a globe valve is based on the movement of the plug, which is guided by a stem and operated by a handwheel or other actuator. In this article, we will delve into the working mechanism of the globe valve in more detail, including how it is designed and how it functions.
How a globe valve is designed?
Globe valves are typically made up of the following parts:
These parts are typically made of metal, such as steel or brass, and are connected together using bolts or other fasteners. The handwheel or actuator is usually located on the top of the valve body, while the stem and plug are inside the body. The seat is usually located around the opening in the middle of the body.
How does a globe valve function?
The function of globe valves is to regulate the flow of fluid through a pipe or other conduit. When the valve is fully open, fluid is able to flow freely through the valve. When the valve is fully closed, the flow of fluid is completely blocked. The movement of the plug is controlled by the stem, which is turned by the handwheel or actuator.
When the handwheel is turned in one direction, the stem moves the plug upwards and away from the seat, allowing fluid to flow through the valve. When the handwheel is turned in the opposite direction, the stem moves the plug downwards and towards the seat, blocking the flow of fluid. The position of the plug can also be adjusted to partially open or close the valve, allowing for fine-tuned control of the flow of fluid.
The flow of fluid through the globe valves is affected by the pressure of the fluid and the resistance of the seat. When the pressure of the fluid is higher than the resistance of the seat, the fluid will flow more easily through the valve. When the resistance of the seat is higher than the pressure of the fluid, the flow of fluid will be restricted.
