Background technique
Common flow control diverter valve generally is to adopt manual tune spool position, or solenoid valve is set makes the spool change location or motor is set outside valve body and drive the spool change location, to realize flow control and shunting.Generally there is following shortcoming in these modes: automaticity and degree of regulation are lower, and be loosely organized, and volume is bigger, and footprints is big, and inconvenience is installed, and the working life of spool counterpart is short etc.
Publication number is that the application for a patent for invention of CN1400413 discloses a kind of low energy consumption and large flow valve, it is a kind of valve that in water body is carried, utilizes valve port place fluid energy to carry out the low energy consumption of valve opening and closing, very little because of operating the power that this valve needs, this valve can be with manually controlling, also can use magnet control, and also be applicable to the valve of unmanned direct control or remote control.This model utility is applicable to agricultural irrigation, water conservancy water delivery and tap water supply engineering.
Summary of the invention
The utility model provides the flow control valve of a kind of automaticity height, compact structure, installation facility, control accuracy height, long service life.
The utility model is provided with valve body, motor, control circuit board, moving valve plate and quiet valve block; Valve body is provided with inlet channel and water outlet, motor and control circuit board be located on the valve body and with the inlet channel and the water outlet seal isolation of valve body, the rotating shaft of motor is connected with moving valve plate, quiet valve block is located in the valve body, moving valve plate is provided with the water flowing slotted eye, quiet valve block is provided with water flowing slotted eye spaced apart, and moving valve plate rides on the quiet valve block.
The center line of the water outlet of valve body overlaps with the center line of inlet channel, parallel or vertical.
Motor preferably is provided with electrical machinery cover.
The rotating shaft of described motor is connected preferably, and the rotating shaft of motor is connected with moving valve plate by link with moving valve plate.
Preferably be provided with inserted tooth on the link, preferably be provided with caulking groove on the moving valve plate, the caulking groove embedding of the inserted tooth of link and moving valve plate connects.
Moving valve plate is preferably the round ceramic moving valve plate.
Quiet valve block is preferably the quiet valve block of round ceramic.
Described quiet valve block is located at the place that is communicated with that preferably quiet valve block in the valve body is located at inlet channel with the water outlet of valve body.
Being preferably end-face friction between moving valve plate and the quiet valve block cooperates.
At the other limit switch that preferably is provided with may command rotating shaft angle of swing of the rotating shaft of motor.Limit switch is used to prevent the excessive rotation of rotating shaft, improves control accuracy.
Working principle of the present utility model: the utility model adopts the driven by motor moving valve plate, the water flowing slotted eye on being located at moving valve plate be located at quiet valve block on corresponding the communicating of water flowing slotted eye the time, the inlet channel of valve body is communicated with water outlet; When the water flowing slotted eye on the moving valve plate covered water flowing slotted eye on the quiet valve block, the inlet channel and the water outlet of valve body were obstructed; Therefore, only need to regulate the angle of swing of machine shaft, can realize controlling the on-off of water outlet and inlet channel, and the size of water flowing flow.
Advantage of the present utility model and effect: owing to adopt motor driving, and establish control circuit board, control program can be pre-set, but motor follow procedure modular working then, make the utility model automaticity height, the control accuracy height is because motor and control circuit board all are located on the valve body, form integral body with valve body, make the very compact and installation facility of the utility model structure.Because moving valve plate and quiet valve block are the round ceramic valve block, when rubbing between the two, the antifriction performance is good, can increase the service life greatly.
