The invention discloses a self-protection automatic control temperature and pressure reducing device. The device comprises an electric temperature and pressure reducing valve, a steam pipeline, a safety valve, a pressure gage, a temperature gauge, a control unit, a check valve, an electric feedwater regulating valve and a stop valve. The electric temperature and pressure reducing valve is providedwith a high-pressure steam inlet, a feedwater inlet, an electric flow rate regulating device for high-pressure steam, a water-vapor mixing cavity and a steam outlet. An inlet of the steam pipeline isconnected with the high-pressure steam inlet. The steam outlet of the electric temperature and pressure reducing valve is in series connection with a protection unit and then connected with a steam output pipeline. The safety valve, the pressure gage and the temperature gauge are connected to the steam output pipeline. Signals of the pressure gage and the temperature gauge are connected to the control unit. Output control signals of the control unit are connected with the control ends of the electric temperature and pressure reducing valve and the electric feedwater regulating valve, and theflow rates of the electric temperature and pressure reducing valve and the electric feedwater regulating valve are controlled simultaneously or alternatively.
Description
Technical field: [0001] The invention relates to a temperature and pressure reduction device, especially a self-protection and automatic control temperature and pressure reduction device and control method for high-temperature and high-pressure steam, which are widely used in petroleum, chemical, electric power, metallurgy and other industries, and the pressure can reach steam above 30.0 MPa. Background technique: [0002] In modern industry, cogeneration of heat and power, central heating (or steam supply), light industry, electric power, chemical industry, textile and other enterprises need to consume a lot of energy in thermal engineering. my country is a country with relatively short energy resources and needs to import a large amount of Energy and energy conservation are more important to our country. Traditional temperature and pressure reduction devices, in high-temperature and high-pressure steam pipelines, the water particles in the steam will bring huge impact damage...
