Wicket-type electric adjusting valve for flow control

Abstract

The invention relates to a wicket-type electric adjusting valve for flow control, applied to flow control process of a central air-conditioning system and other self-control systems. The wicket-type electric adjusting valve consists of a motor, an upper supporting plate, a lower supporting plate, a dual articulated gear, a circlip, an output gear shaft, a bearing, a brace, a rotary arm cover, a circuit board, a manual switch, a travel switch, a circuit board brace, a handle, a casing, a valve body, a flashboard shaft and a valve cover support, wherein the lower end of the valve cover support is connected with the valve body so as to fix the flashboard part of the flashboard shaft to the interior of the valve body; the upper end of the valve cover support is connected with a lower supporting plate so as to fix an output shaft part of the flashboard shaft to an internal hole of the output gear shaft; the motor is installed on the upper supporting plate; the dual articulated gear is fixed to the output shaft of the motor by the circlip; the bearing is respectively embedded on the upper and lower supporting plates; the output gear shaft is meshed with the dual articulated gear; and the upper supporting plate and the lower supporting plate are riveted and positioned by the brace. The wicket-type electric control valve can reduce the power energy consumption, save the material of the valve body and improve the reliability.

Description

technical field [0001] The invention relates to an electric control valve, in particular to an electric control valve which adopts a swing gate valve body and has the functions of position limiting, manual operation and overload resistance. Background technique [0002] At present, the valve body of the electric regulating valve mostly adopts a plug valve or a ball valve. When the plunger valve body is used, its actuator needs to convert circular motion into linear motion, which requires the manufacture of relatively complex mechanical transmission parts, which will inevitably reduce mechanical efficiency. Choosing a relatively high-power motor and more complex mechanical parts will make the product Costs remain high. When ball valves are used, due to the large internal friction of the valve body, it is difficult to make a choice between preventing leakage and reducing power. Contents of the invention [0003] The purpose of the present invention is to provide a swing g...

When the plunger valve body is used, its actuator needs to convert circular motion into linear motion, which requires the manufacture of relatively complex mechanical transmission parts, which will inevitably reduce mechanical efficiency. Choosing a relatively high-power motor and more complex mechanical parts will make the product high cost

When ball valves are used, due to the large internal friction of the valve body, it is difficult to make a choice between preventing leakage and reducing power.
