Power Station Series Regulating Valve

The series of regulating valves for power stations are a new generation of special regulating valves for power stations developed by our company. They are designed for the specific working conditions of regulating valves used in power generation equipment. This series of regulating valves has outstanding characteristics and advantages and is particularly suitable for harsh working conditions, such as feedwater pump recirculation, feedwater control, feedwater startup, main steam drainage, cooling water, boiler blowdown and other harsh conditions that cause flash evaporation, cavitation and vibration tendencies with strong destructive power.

※ Structural Features
Unique and novel valve core
The multi-stage pressure reduction valve core is a sleeve-guided type, which can control high-pressure media very well. This control effect is achieved by allowing the media to pass through a series of pressure drop levels. The pressure drop is graded along several layers of throttling points, and each throttling point consumes a certain amount of energy. After multiple levels of throttling, not only the energy of the fluid itself is consumed, but also the source of flash evaporation and cavitation disappears. The use of cascade valve cores and throttling parts makes this effect the best.
Optimized overall design
The valve body is all forged, and the wall thickness is strictly checked and verified to ensure the high strength and reliability of the valve body.
Simplified design of processing technology
This series of regulating valves all use cascade valve cores with two-notch design, which simplifies the processing technology and disassembly process, and reduces the manufacturing and maintenance costs.
Reduced hot-installation length
A positioning hole and a back-cut groove are added to the top of the valve body and the valve core sleeve to reduce the hot-installation length of the valve body and the valve core sleeve; in addition, in order to ensure concentricity and pressure balance, a positioning guide surface is added to the end of the valve core sleeve, and a return groove is opened.
Good interchangeability:
Most parts of the boiler continuous blowdown regulating valve and the desuperheating water regulating valve are interchangeable and have good interchangeability.
Long service life of valve trims
The surface of the valve trims is all nitrided and hardened, and the Rockwell hardness reaches HRc70 or above, which minimizes the damage to the valve trims caused by wear and flash cavitation; the throttling surface and the sealing surface are separated, which prolongs the service life of the valve trims.
Small maintenance and easy installation
Direct online maintenance, small installation space required, and all connection ends meet standard sizes.

※ FAQ

What are the installation requirements for control valves?
The valve should be installed at the appropriate position of the pipeline to ensure that the flow direction is consistent with the direction indicated by the valve body; secondly, check whether the valve and its accessories are intact before installation to ensure that there is no damage; during installation, ensure that the pipeline connection is stable to avoid stress concentration and prevent damage to the valve; in addition, sufficient space should be provided for the valve to facilitate adjustment, inspection and maintenance; finally, the valve should be protected from excessive vibration or temperature, especially under high pressure and high temperature environments.

What are the common applications of temperature and pressure reducers?
Temperature and pressure reducers are widely used in many fields. They are mainly used in steam systems to reduce high-pressure steam to appropriate pressure to ensure safe operation of equipment. They are commonly used in power, fertilizer, food processing and other industries. They are also used in oil and gas pipelines, chemical production, pharmaceutical plants, etc. to ensure stable pipeline pressure and avoid system overpressure or excessive temperature. In addition, reducers are also used in HVAC, metallurgy and other industries to adjust the temperature and pressure of the fluid in the system to ensure the smooth progress of the process.

How to maintain medium and high pressure valves?
When maintaining medium and high pressure valves, first check the wear of key components such as valve body, valve seat, sealing ring and valve stem regularly. Clean the valve to prevent impurities from blocking and affecting operation. Check the operating performance of the valve to ensure flexible opening and closing without sticking. Check the sealing to prevent leakage and replace the seals if necessary. For valves that operate at high pressure for a long time, it is recommended to perform functional tests regularly to ensure their reliability under high pressure environment. In addition, check the connection parts of the valve to avoid looseness or leakage caused by vibration or corrosion.
