The Application of Hardening Treatment in Industrial Valves

Hardening treatment is a crucial surface engineering technique used to enhance the wear and fatigue resistance of industrial valves while maintaining their internal toughness. This process not only improves the performance of valves but also extends their service life, especially in demanding operational environments. This article explores the application scenarios of hardening treatment, the types of wear it addresses, and specific hardening methods used in industrial valves. Application Scenarios...

An Introduction to Common Body Structures of Ball Valve

Ball valves are a common type of fluid control device, widely used in industries such as oil, gas, chemical processing, power generation, and water supply due to their simplicity, good sealing performance, and long service life. Depending on the valve body structure, ball valves can be categorized into top-entry, two-piece, three-piece, and fully welded types. Each type has its own design advantages and limitations, making it crucial to select the appropriate ball valve for reliable system operation...

Upper Sealing of Globe Valves and Its Optimization

Globe valves are important fluid control devices widely used in various piping systems. Their main function is to regulate or stop the flow of fluid. The sealing performance of these globe valves directly affects their efficiency and lifespan, making the design and application of the upper sealing device particularly crucial. The upper sealing device, commonly referred to as the inverted seal, effectively prevents fluid leakage into the packing chamber while ensuring the normal operation of the...

Understanding Valve Stem Sealing in Soft-Seal Gate Valves

Soft-seal gate valves are widely used in fluid control systems due to their simple structure, ease of operation, and excellent sealing performance. The sealing of the valve stem is a crucial aspect that ensures the normal functioning of the gate valve. The valve stem is not only the core component that drives the gate valve to open and close but also the key to achieving effective sealing. Structural Characteristics of Soft-Seal Gate Valves The basic structure of a soft-seal gate valve typically...

Detailed Procedure for Valve Pressure Testing

Valve pressure testing is a critical step to ensure the safety and reliability of valves during operation. The primary purpose of pressure testing is to verify the strength and sealing performance of valves, ensuring they meet design and manufacturing standards. As essential components of fluid control systems, valve performance directly impacts the overall safety and stability of the entire system. Therefore, a rigorous pressure testing process and detailed inspection standards are crucial...

The Advantages of Ball Valves with Balance Holes

Compared to standard ball valves, ball valves with balance holes feature a unique internal structure design. The most significant distinction is the presence of a small hole, known as the balance hole, located on the ball itself. This balance hole connects to the pipeline's pressure and links to the valve's outlet side, aiming to reduce the pressure differential across the ball when the valve closes. This design helps prevent difficulties in closing the ball valve due to excessive...

Issues and Solutions for Pneumatic Ball Valve Operation

Pneumatic ball valves are widely used in industrial automation systems due to their quick operation, remote control capabilities, and cost-effectiveness. These valves utilize pneumatic actuators to efficiently regulate fluid flow. However, in practical applications, pneumatic ball valves may encounter issues preventing them from opening or closing properly. This article delves into the root causes of these operational problems and offers solutions to help technicians manage and maintain pneumatic...

Industrial Valve Sealing Surface Wear and Repair

Over time, industrial valve disc and seat sealing surfaces naturally wear out due to frequent opening, closing, and exposure to the working medium. This wear reduces the sealing performance, which can lead to leaks and affect system operation, potentially causing safety risks. Therefore, repairing the sealing surface is essential to maintain industrial valve performance. The primary method for restoring sealing is grinding. For valves with mild wear, grinding can restore their sealing ability....
