Working principle of globe valve:

Water is injected from the bottom of the pipe and released toward the pipe’s mouth, assuming there is a water supply line with a cap. The outlet pipe’s cover functions as the stop valve’s closing mechanism. The water will be released outdoors if the pipe cap is manually raised. The water will cease swimming if the tube cap is covered with your hand, which is analogous to the function of a stop valve.

The characteristics of globe valve:

When installed, low in and high out, directional flow, large water friction resistance, convenient production and maintenance, simple structure, high precision; used specifically in hot and cold water supply and high pressure steam pipelines; not applicable Solvents with particulate matter and high viscosity.

Ball valve working principle:

The spherical surface at the inlet and outflow should be entirely visible when the ball valve has rotated 90 degrees. At that point, the valve is closed to stop the solvent from swimming. There should be ball openings at the entrance and the intersection when the ball valve rotates 90 degrees, and they should then open and swim so that there is essentially no flow resistance.
Characteristics of ball valves:

The ball valve is easy to use, quick, and labor-saving. The ball valve can be utilized with fluids that are not very pure (containing solid particles) by simply turning the valve handle 90 degrees. This is because the fluid is affected by the valve’s spherical core when it is opened and closed. is the motion of cutting.

Working principle of gate valve:

A common type of valve is the gate valve, sometimes known as the gate valve. Its closing and closing working principle is that the sealing surfaces of the gate plate and the valve seat, which fit together to block the flow of the medium liquid and enhance the sealing performance using the spring or the physical model of the gate plate, are extremely smooth and consistent. actual outcome. The primary function of the gate valve is to stop the passage of liquid through the pipeline.

Features of gate valve:

The sealing performance is superior to that of a globe valve, the fluid friction resistance is low, opening and closing need more labor, the sealing surface is less degraded by the solvent when fully open, and the sealing performance is unrestricted by material flow direction. The opening and shutting time interval is lengthy, the size is large, and a specific amount of room is needed. When opening and closing, the sealing surface is easily eroded and cut. The two sealing pairs present challenges for processing, maintenance, and production.

Summary of the differences between globe valves, ball valves and gate valves:

While globe valves can be used for both flow regulation and fluid control switch and cut-off, ball valves and gate valves are typically used for fluid control switch and cut-off and rarely for flow regulation. It is better to use a stop valve behind the meter when you need to modify the flow rate. Gate valves are used in control switch and cut-off applications because they are more economically viable. Or, for large-diameter, low-pressure oil, steam, and water pipelines, utilize gate valves. The tightness calls for the usage of ball valves. Ball valves are superior than gate valves in terms of safety performance and lifespan, and they can be utilized in environments with strict leakage criteria. They are also suitable for quick opening and closing.
