Novel gas static pressure throttler with turbocharging function

Abstract

The invention relates to a novel gas static pressure throttler with a turbocharging function. The novel gas static pressure throttler is cylindrical in appearance, a circular groove is formed in the lower bottom face of a throttler body, a motor groove communicated with the circular groove is formed in the lower bottom face of the throttler body, and a circular groove and a spherical groove are formed in the upper surface of the throttler body; a motor is assembled in the motor groove, a cable of the motor is led out through a lead-out hole in the surface of the throttler body to be powered on, and heat generated when the motor is powered on to work is dissipated out through a heat dissipation groove formed in the surface of the throttler. A turbofan assembled in a groove in the lower bottom surface is assembled with a motor rotor, a pressure equalizing plate is arranged between the motor and the turbofan, a pressure equalizing hole is formed in the pressure equalizing plate, an air inlet and an air outlet are formed in the body surface of the throttler, a throttling plate is arranged at an opening in the lower surface of the throttler main body, and a small throttling hole is formed in the throttling plate; when gas enters from the gas inlet and the gas outlet is blocked, the gas enters the gas chamber between the turbofan and the motor, the gas flow is homogenized through the pressure equalizing holes, and then the gas is rotationally pressurized by the electrified turbofan and is ejected out from the small throttling holes in the throttling plate, so that a stable gas film is formed on the working surface. The traditional throttler is difficult to meet the requirement of high bearing capacity of the system, and the bearing capacity of the static pressure system can be improved by more than two times by utilizing the throttling device.
