Rising Stem Flange Gate Valve DN65 PN16 Material HT200 For Piping Systems
Overview of Rising Stem Flanged Gate Valves
Rising-stem flanged gate valves are a common type of gate valve. The following provides an overview of their structural features, operating principles, application scenarios, advantages and disadvantages:
1.Structural Features
Valve Stem: The valve stem features a rising-stem design, meaning the threads are exposed on the outside of the valve body. During valve opening and closing, the stem moves up and down as the gate disc raises and lowers. The position of the stem is visually visible, indicating the valve's open or closed state.
Disc: The disc is a key valve component, typically wedge-shaped or parallel. It fits tightly against the valve seat, blocking the flow of the medium.
Flange Connection: The valve body has flanges at both ends, which connect to the pipe flange via bolts. This connection is easy to install and disassemble, provides excellent sealing performance, and is suitable for piping systems with various pressure and temperature conditions.
Actuation: A common method is handwheel drive, where rotating the handwheel rotates the valve stem, raising and lowering the disc. Other actuation methods include electric, pneumatic, and hydraulic, to meet diverse operating conditions and automation control requirements.
2.Working Principle
Turning the handwheel or other drive device rotates the valve stem. The threaded structure of the valve stem converts this rotational motion into linear motion, thereby raising or lowering the gate disc. When the gate disc is fully raised, the valve is open, allowing the medium to pass freely. When the gate disc is fully lowered and tightly seated against the valve seat, the valve is closed, blocking the flow of the medium.
3.Applications
Water supply and drainage systems: Used to control the flow of water in urban water supply and drainage pipelines, such as the inlet and outlet pipes of water plants and the water supply mains in residential communities.
Industrial pipelines: Used to shut off or connect various media such as oil, natural gas, steam, and cooling water in industrial sectors such as petroleum, chemical, power, and metallurgy.
Fire protection systems: As a key valve in fire protection pipelines, it is used to quickly open or close the water flow in the event of a fire, ensuring the supply and control of firefighting water.
4.Advantages
Intuitive opening and closing status: The rising stem design allows the operator to quickly and accurately determine whether the valve is open or closed by observing the position of the valve stem, reducing the possibility of misoperation.
Easy Maintenance: Because the valve stem threads are exposed, they are easier to inspect, lubricate, and replace during repair and maintenance.
Excellent Sealing: The sealing surface between the gate and valve seat is precision-machined, providing a strong seal and reducing the risk of media leakage.
