Drawings
FIG. 1 is a schematic structural diagram of an electronic flow controller according to the present invention;
FIG. 2 is a schematic diagram of a PWM wave flow regulation process of the electronic flow controller according to the present invention;
fig. 3 is a schematic flow chart of a PID model of an electronic flow controller according to the present invention.
In the figure: 1. a valve body; 2. a threaded sleeve; 3. a handle; 4. a locking device; 5. a valve needle; 6. a seal ring; 7. an outlet; 8. an inlet; 9. a sealing surface; 10. and a controller.
Detailed Description
The technical solutions in the embodiments will be described clearly and completely with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments, but not all embodiments.
Example one
Referring to fig. 1-3, the electronic flow controller comprises a valve body 1, a threaded sleeve 2 is arranged on the valve body 1, a handle 3 is arranged at one end of the threaded sleeve 2, a locking device 4 is arranged at the top of the valve body 1, the locking device 4 is matched with the threaded sleeve 2, a valve needle 5 is arranged in the threaded sleeve 2, a controller 10 is arranged on one side of the valve body 1, and the controller 10 adopts PWM waves.
In this embodiment, the thread insert 2 is provided with two sealing rings 6, and the two sealing rings 6 are both located in the valve body 1.
In this embodiment, the two sides of the valve body 1 are respectively provided with an outlet 7 and an inlet 8, a sealing surface 9 is arranged in the valve body 1, and the sealing surface 9 is positioned between the outlet 7 and the inlet 8.
The working principle is as follows: 10 control handle 3 of controller, flow is through 8 entering valve body 1 of import in, handle 3 drives needle 5 and adjusts from top to bottom, and needle 5 drives sealed face 9 and reciprocates, and sealed face 9 is close to export 7 and comes 1 interior flow of control valve body, promptly: the period of the PWM wave is a fixed value, in the PWM period, only two states of opening and closing are provided, the opening time is ton, the closing time is toff, the sum of the opening time and the closing time is equal to the PWM period, the flow rate is adjusted by adjusting the time of ton, namely adjusting the duty ratio of the electromagnetic valve, when the time of ton is longer, the toff time is shorter, the flow rate is larger, otherwise, the flow rate is smaller. The specific value of Ton is calculated by the control system according to the P.I.D. parameter.
All structures in this application can carry out the selection of material and length according to actual use condition, and the attached drawing is schematic structure chart, and specific actual dimensions can make appropriate adjustment.
The above descriptions are only preferred embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the scope of the present invention, and the technical solutions and the utility model concepts of the present invention are equivalent to, replaced or changed.
