Pneumatic valve drain water vapor flow condition of boiler plant control pneumatic valve selection and application

but the first thing to consider is safety and reliability of pneumatic control valve. Water supply pneumatic valve ( Lord, attached to the boiler feed water is a compound feed water regulating pneumatic valve pneumatic valve control requirements: control boiler into the water to ensure steam evaporation, maintain boiler water level ( Main pneumatic valve, enclosed type boiler feed water system consists of two control pneumatic valve, one for the boiler starts to use, a water supply for normal use. Condition: the boiler startup pressure pneumatic valve general da Kg,. Pneumatic valve drain water vapor flow condition of boiler plant control pneumatic valve selection and application of power flow is actually simple water, steam cycle processes, pneumatic control valve is used in the in this process is both simple and complex. Simple process medium is simple, only two kinds of water and steam and water is complicated and the steam temperature and pressure range is big, bring a series of questions such as: flashing, cavitation, flushing, noise, erosion. But the first thing to consider is to control the safety and reliability of pneumatic valve. Our main products are: pneumatic pneumatic valves, pneumatic ball valves, pneumatic butterfly valve, pneumatic actuators, http://www. /。 Water supply pneumatic valve ( Lord, attached to the boiler feed water is a compound feed water regulating pneumatic valve pneumatic valve control requirements: control boiler into the water to ensure steam evaporation, maintain boiler water level ( Main pneumatic valve, enclosed type boiler feed water system consists of two control pneumatic valve, one for the boiler starts to use, a water supply for normal use. Copyright notice: this site offers information, if you need more detailed information, please contact the site customer service. Condition: the boiler startup pressure pneumatic valve general da Kg, flow is small, when normal operation of the pressure difference is small, large flow, flow adjustable ratio of / - /。 Pneumatic valve requirements: WCB/WC, for double pneumatic valve in the system to start the pneumatic valve requires the cavitation resistance, V closed ranks, composite pneumatic valve need to use water for characterization of pneumatic trims and satisfied the needs of the boiler startup and normal operation.

Special note: all comments do not represent the home station article reprinted on view, such as the need of related products, please contact the site, all peer originator. Boiler feed pump minimum flow cycle of pneumatic valve control requirements: the boiler feed water pump start-up and resting safe operation and eliminating because flow is too small, temperature increase, water pump cavitation damage strongly. ( Old plant is using the minimum flow control mode of pneumatic valves, as well as the use of mechanical pump automatic cycle of pneumatic valve. Pneumatic pneumatic valve manufacturer. Condition: da pressure drop Kg, is the largest power station in the system under differential pressure pneumatic valve, flow for the normal flow of %. Pneumatic valve requirements: resistance to cavitation, block structure, grade V seal level, pump start-up continuous working and resting runtime pneumatic valve, pump normal boot after the pneumatic valve closed, pneumatic valve is usually a failure. High-low heater drain pneumatic valve ( Feed water heater hydrophobic hydrophobic, condensed water heater control requirements: control the location of condensed water heater, timely will condensate discharge, high water discharge, the normal water level hydrophobic condition: saturated water, heater control pneumatic valve differential pressure is commonly - between Kg, the final level of hydrophobic pneumatic valve connected directly to the condenser or deaerator. Pneumatic valve requirements: resistance to flash flushing, V or VI seal level, pneumatic valve is usually a failure. The deaerator water level control pneumatic valve ( DALC control requirements: provide traffic keep deaerator water level, normal progress by joining the steam temperature, eliminate the gas dissolved in the water. Condition: startup phase flow is small, the differential temperature, normal flow, small pressure difference, working condition of similar water supply pneumatic valve. Pneumatic valve requirements: effective during low flow resistance to cavitation. Cooling air valve ( Attemperator control requirements: the high pressure water injection into the steam to steam temperature control requirements and working conditions: water, the pressure difference is bigger, pneumatic valve requirements: a variety of types: type nozzle, auxiliary atomization type, self-contained type and type to the clamp. Pneumatic valve, desuperheating decompression High and low pressure pneumatic valve control circuit: the high temperature and high pressure steam to adjust to a certain temperature and pressure of steam, to provide a turbine bypass channel, boiler turbine and work independently. Working conditions: high temperature and high pressure steam. Pneumatic valve requirements: thermal shock, noise reduction, response quickly. http://www pneumatic pneumatic valve manufacturer. /。
