Abstract
The utility model discloses a super-miniature electric control valve, which comprises a motor, a gear set controlled by the motor, and a control valve body. A valve spool and a valve seat are arranged inside the control valve body; a valve rod is connected on the valve spool; and the valve rod is driven by the motor. The electric control valve also comprises a control device, and the control device comprises a central controller, and a sensor which is controlled by the central controller. The sensor detects the position of the valve rod; the central controller controls the motion of the motor; and a protective sleeve is arranged outside the gear set. The super-miniature electric control valve has the advantages of small volume and high control precision, can be applied to an automation control system in electric power, metallurgy and light industry, and is particularly suitable for low-flow high-precision control.

Technical field
The utility model relates to a kind of extra small formula electric control valve, more particularly, is the numerically controlled extra small formula electric control valve of a kind of employing.
Background technique
The extra small formula electric control valve that uses mainly adopts open gear train at present, lubricant oil is splashed, contaminated equipment everywhere.In addition, the control module that present mortor operated valve modulating valve adopts is analog, debugs complicated low precision, and can not emergency cock when breaking down, so need a new extra small formula electric control valve solve the problems referred to above.
The model utility content
For solving the problems referred to above that prior art exists, the utility model proposes a kind of extra small formula electric control valve, have the control accuracy height, the characteristics that volume is littler.
The utility model can be solved by the following technical programs:
A kind of extra small formula electric control valve, comprise a motor, and the gear train of this Electric Machine Control, an and modulating valve main body, be provided with a spool and a valve seat in the described modulating valve main body, connect a valve rod on the described spool, described valve rod is subjected to described motor driving, this electric control valve also comprises a control gear, described control gear comprises a central control unit, reaches a display screen and a keyboard that is connected with this central control unit and a sensor that is subjected to central controller controls, the position of the described valve rod of described sensor; The motion of the described motor of described central controller controls; The outside of described gear train is provided with a protecting jacket.
Motor described in the utility model is the synchronous machine of rareearth magnetic material.
A kind of extra small formula electric control valve described in the utility model comprises that also one manually installs, and described manual operating device is arranged on the top of this electric control valve.
Since adopt above technological scheme, extra small formula electric control valve of the present utility model, performance has had very big progress, and quality is greatly improved, as: 1, owing to increased the separation sleeve protection, grease can not be gone out, and has protected gear, does not have greasy dirt; 2, owing to increase the armstrong's patent device, when nonserviceabling, can pass through manual operating device, valve is carried out switch control; 3, the synchronous reversible electric machine that has adopted rareearth magnetic material to make now makes actuator's volume littler, and weight is lighter.4, owing to adopted the digital intelligent control module, and LED operation indication is arranged, precision is greatly improved, and error is very little, in control accuracy≤0.5%, and adopts electronic limit switch, miniaturization more.
