The invention discloses an intelligent downhole throttling valve capable of being closed under emergency for gas wells, which comprises a delivery mechanism and a downhole throttling mechanism. The intelligent downhole throttling valve is characterized in that the downhole throttling mechanism comprises a working barrel, the lower end of the working barrel is connected to a lower connector, the lower end of the working barrel is connected to a protective barrel, an internal core barrel is arranged in the protective barrel, an annular space is formed between the protective barrel and the internal core barrel, a temperature and pressure test tool and a high-temperature motor are arranged in the internal core barrel, an output shaft of the high-temperature motor is connected to a mover of a throttling nozzle, an adjusting base of the throttling nozzle is mounted in the lower connector, the lower end of the lower connector is connected to a sand filter screen, and a fluid passage in the sand filter screen corresponds to an adjusting hole in a stator of the throttling nozzle. By detecting pressure behind the nozzle, a controller of the temperature and pressure test tool controls the motor to drive a rotary shaft to rotate to adjust the opening degree of the throttling nozzle, so that the pressure behind the throttling nozzle is stabilized within a set range, consequently, the pressure of wellhead production is stabilized, and the efficiency of construction is further increased.
