The invention discloses an air release device special for a steam turbine, and relates to the field of steam turbines. By aiming at the problems that a traditional air release device special for a steam turbine cannot accurately control the gas flow and cannot reduce the equipment temperature in time, the following scheme is provided, wherein the air release device special for the steam turbine comprises a shell, an isolation layer is fixedly arranged in the shell in a sleeved manner, a cold gas layer is arranged between the isolation layer and the shell, a temperature sensor and a gas pressure sensor are fixedly connected to the inner wall of the left side of the isolation layer, a data display screen is fixedly connected to the outer wall of the left side of the shell, a first push rod motor is fixedly connected to the top of the shell, a flow limiting block is fixedly connected to an output shaft of the push rod motor, and a spring is arranged on the outer portion of the output shaft of the push rod motor. According to the air release device, by controlling the gas pressure value in the shell, accurate gas release can be achieved, and therefore accurate control over the gas flowis guaranteed, equipment can operate normally, meanwhile, the temperature of the equipment can be reduced in time, and the service life of the equipment can be prolonged.
Description
technical field [0001] The invention relates to the field of steam turbines, in particular to a special air discharge device for steam turbines. Background technique [0002] The steam turbine, also known as the steam turbine engine, is a rotary steam power device. The high-temperature and high-pressure steam passes through the fixed nozzle to become an accelerated air flow and then sprays onto the blades, so that the rotor equipped with blade rows rotates and works externally at the same time. Steam turbines are the main equipment of modern thermal power plants, and are also used in metallurgical industry, chemical industry, and ship power plants. Modern steel plants also use steam turbines in large quantities. The traditional ventilation device dedicated to the steam turbine cannot accurately control the gas flow, which affects the working effect of the steam engine, and cannot reduce the temperature of the equipment in time, which affects the service life of the equipment...
