Abstract
The utility model provides a proportional electric control flow control valve which comprises a control panel (2), a motor (3) and a valve body (9). The valve body is provided with a water inlet (1) and a water outlet (8), and the control panel is electrically connected with the motor. The proportional electric control flow control valve further comprises a first gear (5), a second gear (6) and a valve barrel (7). The first gear is fixed on the motor shaft of the motor and can be driven to rotate by the motor, and the second gear is meshed with the first gear. The valve barrel is located in the valve body and can be driven to rotate by the second gear. An opening (11) is formed in the position, identical with the water outlet in height, of the side face of the valve barrel. In the rotating process of the valve barrel, when the opening approaches the water outlet gradually, the area of the circulating surface of the water outlet is enlarged gradually, and thus water outflowing amount is enlarged. The water outflowing amount reaches the maximum when the opening exactly faces the water outlet, the valve barrel rotates continuously, and the water outflowing amount is reduced when the opening becomes far away from the water outlet gradually.
Description
Technical field
The utility model relates to a kind of flow control valve, the automatically controlled flow control valve of especially a kind of proportion expression.
Background technique
In the prior art, the fluid control field such as pneumatic and hydraulic pressure is often controlled fluid state with various valve bodies.But, only have unlatching its normally used automatic driver (as solenoid valve), close two kinds of working staties, but not proportion expression controls, cannot meet high-precision linear change control operation.And the accurate operation that reduces or increase in order to obtain (continuous) liquid flux of ratio, need to coordinate and could realize from the precision machining between the different valve members of driving mechanism, this Proportional valve is complex structure often, volume is large, the normal PLC of employing controls, be applied to industrial occasions, price is also higher, is not suitable for the application of some miniaturization household electric appliance.And also have at present people at development of miniaturized Proportional valve, as apply for disclosed 201210442470 patents-numerical scale control valve, it adopts the feed screw nut with permanent magnet, coordinate rotating electromagnetism winding, adopt magnetic force to carry out becoming rotatablely moving straight line motion, valve rod can be become the aperture of valve pocket import large or diminish by straight line motion, reach the object of proportional control.But this scenario-frame is complicated, processing technology requires high, and the non-contact transmission between electromagnetic force and permanent magnetism nut, has certain error and likely has the motionless situation of transmission.
Model utility content
The technical problem that the utility model solves is to provide a kind of highi degree of accuracy proportion expression flow control valve with simple structure.
In order to address the above problem, technical solution adopted in the utility model is: the automatically controlled flow control valve of a kind of proportion expression, comprises control panel, motor, valve body, valve barrel; Control panel is electrically connected to motor; Valve body is provided with water intake and water outlet, and valve barrel is positioned at valve body; Also comprise the first gear, the second gear; The first gear is fixed on the motor shaft of motor and can be rotated by driven by motor, the second gear and the engagement of the first gear; The second gear is fixedly connected with valve barrel.
The beneficial effects of the utility model are: when reaching accurate ratio adjust flux object, this electrically-controlled valve simple in structure, volume is little, therefore manufacturing process is simple, economical and practical; Because the Flow-rate adjustment of this electrically-controlled valve is mainly realized by simple and mechanical transmission, therefore the regulating action instantaneity being risen is good, working stability is reliable.To sum up, electrically-controlled valve provided by the utility model is applicable to household appliance technical field.

Embodiment
By describing technology contents of the present utility model, structure characteristics in detail, being realized object and effect, below in conjunction with mode of execution and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1 and Fig. 2, mode of execution of the present utility model provides a kind of proportion expression automatically controlled flow control valve, comprises control panel 2, motor 3, valve body 9, valve barrel 7, and valve body is provided with water intake 1 and water outlet 8, and valve barrel is positioned at valve body; Control panel is electrically connected to motor; Also comprise the first gear 5, the second gear 6; The first gear is fixed on the motor shaft of motor and can be rotated by driven by motor, the second gear and the engagement of the first gear; The second gear is fixedly connected with valve barrel.
The working principle of the automatically controlled flow control valve of aforementioned proportion formula is as follows: control panel is controlled electric machine rotation, electric machine rotation drives the first gear to rotate, and the second gear rotates with the first gear, and valve barrel rotates with the second gear, by the motion of the relative valve body of valve barrel, realize the adjusting to flow.
Preferably, in valve barrel side and the contour position of water outlet, have opening 11, in valve barrel rotation process, opening is gradually near water outlet, and water outlet circulating face area increases gradually, therefore water-outlet quantity increases gradually; When opening during over against water outlet the water outlet water yield reach maximum; Valve barrel is rotated further that opening is gradually away from water outlet, and water outlet circulating face area reduces gradually, and water-outlet quantity reduces gradually.When needs tune up the water yield again, can make motor transposing sense of rotation, also revolution thereupon of valve barrel, opening approaches water outlet once again; Also can make motor continue former direction rotates one week after-opening and approaches once again water outlet.
Preferably, the circumference bilateral symmetry in valve barrel side and the contour position of water outlet has two place's openings, and in valve barrel rotation process, opening is gradually near water outlet, and water outlet circulating face area increases gradually, therefore water-outlet quantity increases gradually; When opening during over against water outlet the water outlet water yield reach maximum; Valve barrel is rotated further that opening is gradually away from water outlet, and water outlet circulating face area reduces gradually, and water-outlet quantity reduces gradually.When needs tune up the water yield again, can make motor transposing sense of rotation, also revolution thereupon of valve barrel, opening approaches water outlet once again; Also can make motor continue former direction and rotate after nearly half cycle, another opening that valve barrel side and aforementioned opening are circumference symmetry moves closer to water outlet.
Preferably, between import and valve body, be provided with Hall flow sensor 10, and be electrically connected to control panel; Fluid enters by Hall flow sensor and enters valve pocket from water intake, Hall flow sensor is passed to control panel by signal, obtain by analysis present flow rate information and compare with expectation flow, show that corresponding pwm control signal transfers to control chip, control chip output signal makes motor clockwise or rotates counterclockwise.
Preferably, also comprise valve gap 4, motor and valve body are all fixedly assemblied on valve gap.
Preferably, described motor is direct current generator, stepper motor or synchronous machine.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
