High Temperature and High Pressure Desuperheating Device

The temperature and pressure reduction device is a steam thermal energy parameter (pressure, temperature) conversion device and a waste heat energy-saving device widely used in thermal energy projects in modern industries such as cogeneration, central heating, steam and light industry, electric power, chemical industry, and textile enterprises. Through this device, the steam parameters provided by the user are reduced to the required appropriate temperature and pressure to meet the user's requirements, and it can fully save thermal energy and use thermal energy reasonably.

※ Device Introduction
This device consists of a cooling system, a pressure reducing system (or a cooling and pressure reducing system), a safety system, a thermal control system, and a main steam pipe body. It is a new generation of high-temperature and high-pressure cooling and pressure reducing device produced by our company. It digests and absorbs the structural forms of well-known domestic and foreign brands, has been optimized and designed, and has been confirmed by users to be a stable, safe and reliable product. The valve seat and valve core of this optimized design have a wide adjustment range, stable performance and low noise operation. Its advantages are:
1. Excellent flow characteristics, which can adapt to a wide range (10-100%) of steam load changes.
2. Balanced valve core, reducing actuator torque.
3. The valve core and valve grid sealing surface are welded with "Stellite" alloy to resist erosion.
4. The lowest leakage rate.
5. Low noise design.
6. The optimized pressure reducing valve upper structure makes it easy to disassemble and assemble the internal components without removing the valve body during maintenance.

※ Specifications

※ Product Advantage
1. The temperature reduction and pressure reduction are completed in the same valve body, which greatly shortens the length of the whole device. The structure is more compact and reduces the floor space.
2. The temperature reduction and pressure reduction valve adopts a double valve seat structure, with small unbalanced force, wide adjustment range, smooth movement, and no stuck phenomenon. It adopts a straight stroke actuator, removes the traditional lever hinge mechanism, reduces the idle stroke link, and further improves the sensitivity of the system.
3. The temperature reduction system adopts different forms of water supply regulating valves according to the different pressure differences of the temperature reduction water, which can not only reduce the leakage of the valve, but also reasonably distribute the pressure difference on the water system.
4. The temperature reduction and pressure reduction valve and the water supply regulating valve can be equipped with electric or pneumatic diaphragm actuators according to the actual working conditions of the user's site to meet the needs of the user.

※ 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.
