Revealing the working principle, type characteristics, and installation points of globe valves

Globe valves, also known as shut-off valves, work on their unique opening and closing characteristics. During the opening or closing process, the friction between its sealing surfaces is relatively small, ensuring its durability. In addition, the height required for its opening is not large, the manufacturing process is relatively simple, and maintenance is also quite convenient.

Comprehensive understanding of check valves: detailed explanation of classification, selection, and standards

Clamp type butterfly valves and flange type butterfly valves are two common types of butterfly valves. Both types of butterfly valves have a wide range of applications, but many friends cannot distinguish between clamp type butterfly valves and flange type butterfly valves and are not familiar with the differences between the two. The clamp and flange of butterfly valves are two connection methods. In terms of price, the clip on type is relatively cheaper ..

Complete explanation of the principle, types, and experimental methods of check valves

A check valve, also known as a check valve, one-way valve, reverse flow valve, and back pressure valve, is a type of valve that automatically opens and closes based on the activity of the medium itself. Its core function is to prevent medium backflow, protect the pump and drive motor from reverse effects, and also achieve the release of container medium.

Working mechanism and common fault analysis of check valve

Check valve, this type of valve, its core function is to allow the medium to flow only in one direction while preventing its reverse flow. This type of valve usually has the characteristic of automatic operation. When pressure is applied to the fluid in one direction, the valve disc will open to allow flow; When the fluid attempts to flow in the opposite direction, the fluid pressure and the self weight of the valve disc will work together, causing the valve disc to tightly adhere to the valve seat, thereby completely cutting off the flow.

Unveiling Butterfly Valves: A Comprehensive Analysis from Structure to Working Principle

Butterfly valve, also known as butterfly valve, is designed based on the free rotation of butterflies dancing in the wind. The core component, the valve disc, is disc-shaped and rotates around an axis inside the valve seat. By rotating the angle, the opening degree of the valve can be controlled, thereby achieving the function of fluid control.

Practical and durable, flange butterfly valve structure, function and maintenance points

In industrial pipeline systems and many civilian fluid transportation fields, valves play a key role in accurately controlling flow, cutting off or regulating medium transmission, and flange butterfly valves have become widely used products due to their unique advantages. To ensure its continuous and efficient operation, it is essential to have a deep understanding of its structure, functions, and maintenance points.

Analysis of the working principle, installation precautions, and application scenarios of Y-shaped filters

The Y-shaped filter, as an indispensable device in water, oil, gas pipelines and various equipment, its core function is to remove impurities from the medium. It is installed at the front end of each supporting valve in the inlet pipeline to ensure that impurities are left in the filter barrel, thereby protecting the valves and other equipment from mechanical debris and ensuring their normal operation.

Internal thread ball valve: structure and application

Internal thread ball valve, also known as internal thread ball valve or internal thread ball type globe valve, is a common type of valve. Its main feature is to open or close fluid channels by rotating 90 degrees. Its working principle is to control the flow of fluid through a sphere. When the sphere rotates parallel to the pipeline axis, the fluid can pass through; When the sphere rotates 90 degrees perpendicular to the pipeline axis, the fluid flow is completely cut off.
