Problems solved by technology

[0002] Most of the existing air pressure regulating valves are manually controlled. By observing the air pressure gauge, turn the valve bit by bit to make the air pressure reach the characteristic value. This adjustment process is relatively long and cannot reach the required air pressure value in time.

Abstract

The invention discloses an airflow pressure regulating valve. The regulating valve comprises an airflow regulating shell, an regulating valve body and a stepping motor, wherein the airflow regulatingshell sequentially comprises an air inlet end, an regulating end and an air outlet end, the regulating valve body is arranged in the regulating end, and the regulating valve body is connected with anoutput shaft of the stepping motor. According to the regulating valve, airflow flows out the air outlet end from the air inlet end through the regulating valve body, according to the flow value of theairflow, the ventilation area is controlled by the rotation angle of the valve driven by the stepping motor so as to control the pressure of the airflow, an inner cavity is design to be spherical soas to enable the ratio of the rotation angle of the regulating valve body to the pressure of the airflow to be closer to be linear, so that controlling is rapider and more accurate.

Description

technical field [0001] The invention relates to an airflow pressure regulating valve. Background technique [0002] Most of the existing air pressure regulating valves are manually controlled. By observing the air pressure gauge, the valve is turned little by little to make the air pressure reach the characteristic value. This adjustment process is relatively long and cannot reach the required air pressure value in time. In this regard, we have developed a regulating valve that can electrically control the airflow pressure faster and more accurately to solve the above problems. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide an airflow pressure regulating valve. The airflow flows out from the air inlet end through the regulating valve and the air outlet end. To control the airflow pressure, the design of the spherical inner cavity makes the ratio of the adjustment valve rotation angle to the airflow pressur...
