As an embodiment of the present invention, the shape of the adjusting groove 37 is an arc-shaped strip, and the adjusting groove 37 is annularly and uniformly arranged on the two adjusting plates; during operation, because the inside liquid flow size of locking ring 3 is relevant with the size of two adjustment tank 37 crossing area, this moment through setting up adjustment tank 37 into curved rectangular form, make crossing area between two adjustment tank 37 become linear ratio with No. two adjustment plate 38's rotation angle, thereby make the operator carry out the area of intercommunication between two adjustment tank 37 of reasonable quantitative control according to bull stick 35's rotation angle, thereby make flow control valve's flow control more accurate and quick, and through the form that sets up adjustment tank 37's distribution, can effectual increase two adjusting plate's working area and control range, thereby the regulation and control scope of flow control valve has been strengthened greatly.
In one embodiment of the present invention, the angle of the adjusting groove 37 corresponding to the arc length of the sliding groove 33 is the same, and the side surface of the locking ring 3 on one side of the sliding groove 33 is marked with scale marks; when the angle corresponding to the arc length of the sliding chute 33 is too large, the first magnet 34 in the sliding chute 33 is easy to cause the two corresponding adjusting grooves 37 on the two adjusting plates to be crossed due to the too large rotating angle, therefore, the adjusting plate is unstable when adjusted, at the moment, the sliding track of the first magnet 34 in the sliding groove 33 can be effectively limited by setting the angle corresponding to the arc length of the adjusting groove 37 and the sliding groove 33 to be the same angle, the instability of the first magnet 34 when adjusted by two adjusting plates due to overlarge rotating angle is reduced, meanwhile, the scale marks are marked on the side surface of the locking ring 3 on one side of the sliding groove 33, so that an operator can more accurately and quantitatively adjust the adjusting grooves 37 on the two adjusting plates according to the marks of the scale marks, and the accuracy of the flow control valve in regulation and control is further improved.
When the inlet pipe 11 and the input pipe 13 work, firstly, the axes of the fixing rings 2 on the inlet pipe 11 and the input pipe 13 are aligned, then the annular plates 31 at the two ends of the locking ring 3 are respectively inserted into the annular grooves 21 on the fixing rings 2, and the first clamping groove 32 on the annular plate 31 is respectively aligned with the second clamping groove 22 at the inner end of the annular groove 21, then the locking rods 23 at the second clamping groove 22 are inserted into the two clamping grooves and are used for fixing and limiting the annular plate 31 at the first clamping groove 32, so that the inlet pipe 11 and the input pipe 13 are respectively connected and communicated with the two ends of the locking ring 3, and at the moment, the locking ring 3 is set to be in a form convenient to install and detach, so that the adjusting mechanism in the locking ring 3 can be replaced and maintained more conveniently and rapidly when a fault occurs; when the control valve needs to control and adjust the flowing liquid, the rotating rod 35 inside the sliding groove 33 is rotated to drive the first magnet 34 to rotate synchronously, the second magnet 39 attracted with the first magnet 34 drives the second adjusting plate 38 to rotate synchronously under the action of the first magnet 34, and the flow of the liquid can be controlled by adjusting the intersection area of the notches of the adjusting grooves 37 on the first adjusting plate 36 and the second adjusting plate 38 when the second adjusting plate 38 rotates, so that the control valve body 1 is pre-adjusted before manual adjustment, meanwhile, the accuracy and the flexibility of the flow control valve can be improved through two manual adjusting sets, and the working quality and the service life of the flow control valve are greatly improved.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
