Functions of Plate-Type Check Valves and Arrow-Type Check Valves
Plate-Type Check Valves and Arrow-Type Check Valves are both types of non-return valves used to prevent the backflow of fluids. They have their own uses and characteristics in oil drilling, chemical pipelines, and other industrial applications. Here are their main functions:
Functions of Plate-Type Check Valves:
1.Simple Structure
Plate-Type Check Valves typically have a simple structure, consisting of a valve body and a freely swinging valve plate.
2.Low Pressure Drop
Under normal flow conditions, the low pressure drop of Plate-Type Check Valves helps reduce resistance to fluid flow.
3.Suitable for High Flow Rates
Due to their structural characteristics, Plate-Type Check Valves are suitable for situations requiring high flow rates.
4.Easy Maintenance
The simple structure of Plate-Type Check Valves makes maintenance and replacement relatively easy.
5.Full Open State
When fluid flows in the correct direction, the valve plate fully opens, reducing the pressure drop of the fluid.
Functions of Arrow-Type Check Valves:
1.Rapid Response
Arrow-Type Check Valves can quickly respond to changes in fluid flow due to their special shape, opening or closing swiftly.
2.High Precision Control
Arrow-Type Check Valves provide more precise fluid control, suitable for situations requiring fine control of fluid backflow.
3.Suitable for Low Flow Rates
Arrow-Type Check Valves are appropriate for low flow rates or precise control fluid systems.
4.Low NoiseWhen closing
Arrow-Type Check Valves can reduce water hammer effects and noise.
5.High Reliability
The design of Arrow-Type Check Valves ensures high reliability even under high pressure and high flow rates.
6.Self-Cleaning Function
The special shape of Arrow-Type Check Valves helps reduce the accumulation of impurities in the fluid on their surface, offering some self-cleaning functionality.
Both Plate-Type and Arrow-Type Check Valves are used to prevent fluid backflow, but their designs and application scenarios differ. The choice between these types of check valves depends on specific industrial application needs, including the properties of the fluid, flow rate, pressure, and operating conditions.
