The working principle of butterfly valves and ball valves
Butterfly valves are suitable for pipelines transporting various corrosive and non-corrosive fluid media in power generation, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical metallurgy, power generation environmental protection, and building water supply and drainage engineering systems.
Research on the Control and Detection Technology of Electric Actuators for Valves
The correct operation of automatic valve actuators can create favorable conditions for the optimized handling of valve detection technology. This article first summarizes and analyzes the shortcomings in the design process of key factors such as the control interface of automatic valve actuators, and formulates an optimized control and detection strategy for automatic valve actuators, which is of great significance to improving the operation quality of valve devices in the new era.
Six major causes of valve sealing surface damage
Since seals in valve passages play a role in shutting off and opening, regulating and distributing, separating and mixing media, the sealing surfaces are often subject to corrosion, erosion, and wear from the media, making them easily damaged.
A pneumatic valve is a valve driven by compressed air, using compressed air to drive the movement of multiple sets of combined pneumatic pistons in the actuator.
Top tricks to combat valve corrosion
Metal valves can be considered key components in engineering equipment that are *easily* prone to corrosion and failure. Typically, the sealing surfaces, stems, diaphragms, and small springs of metal valves generally use first-grade materials, while the valve body and valve cover use second- or third-grade materials. For valves used in high-pressure, highly toxic, flammable, explosive, or radioactive media, materials with very low corrosiveness are selected.
Introduction to the main accessories of the regulating valve
The valve positioner is a key accessory for pneumatic actuators. It is used in conjunction with pneumatic actuators to improve valve positioning accuracy and overcome the effects of stem friction and media imbalance, so that the valve can be accurately positioned according to the signal from the regulator.
