During described cam rotation, the horizontal movement of self-locking driven member 704 that is connected with cam guide 705 will be driven, First cam 615 control the first follower 7-1 and the second follower 7-2 the second part installation groove 709 in self-locking from The horizontal movement of moving part 704, the second cam 616 control the first follower 7-1 and the second follower 7-2 the first part installation The horizontal movement of self-locking driven member 704 in groove 708.
Described PLC is subjected to the programming in logic of user, and by the time control parameter and Ge Tong needed for user The storage of road break-make control parameter, the rotation of stepper motor 1 is controlled to drive the cam 616 of the first cam 615 and second to act, So as to obtain the state of a control that first passage, second channel, third channel, fourth lane need.
A kind of principle of programmable four-way valving is as follows：
The control parameter by time control parameter and four passages is needed to be input in PLC according to control, PLC controls The rotation of device control stepper motor 1 processed；Because power input shaft 602 passes through the motor shaft phase of yielding coupling 2 and stepper motor 1 Even, stepper motor 1 can drive cam mechanism 6 to rotate；Due between first gear 603 and second gear 607, the 3rd gear 609 and the 4th angled diminution between gear 610 act on, when stepper motor rotates larger angle and power output shaft 611 only Less angle is rotated, so as to improve the control accuracy of device；Due to the first unilateral bearing 613 when turning clockwise bearing lock Bearing is locked during dead and the second 614 rotate counterclockwise of unilateral bearing, therefore power output shaft 611 turns clockwise and is only capable of drive first Cam 615 rotates and rotate counterclockwise is only capable of driving the second cam 616 to rotate；First cam 615 or the second cam 616 rotate, The horizontal movement of self-locking driven member 704 being connected with it by cam guide 705 can be driven；Due to flexible pipe top tight pieces 706 The inclined-plane of inclined-plane and self-locking driven member 704 is in contact, and the rotary motion of the first cam 615 or the second cam 616 eventually converts Into flexible pipe top tight pieces 706 vertical movement and hold out against or loosen first passage flexible pipe 10, second channel flexible pipe 11, third channel Flexible pipe 12, fourth lane flexible pipe 13, so as to control first passage, second channel, third channel, fourth lane.Due to described First follower 7-1, the second follower 7-2 have mechanical self-latching property, when the first cam 615 or the second cam 616 When driving self-locking driven member 704 moves to a position, even if power output shaft 11 is no longer supplied to the first cam 615 or the The power of two cam 616, the position that self-locking driven member 704 can also be maintained at previous is constant, until the first cam 615 or second is convex Wheel 616 regains power and changes the position of self-locking driven member.Due to this principle, a stepper motor 1 is just achieved 4 The switch control of individual passage and aperture regulation do not influence each other.
The beneficial effect of present embodiment is：1st, present embodiment device is due to the valve element in the absence of activity and passage and its In controlling organization structure independently of one another, internal leakage and the generation of external leakage can effectively be prevented.
