Abstract
The present invention provides a kind of eccentric drive change valve devices.The eccentric drive change valve device includes：Drive set controller (11) accurately controls driving device (10) starting, stopping and rotation speed, rotation angle, rotation torque etc.；Circumferential position of transmission shaft (13) internal keyway by square key pin (19) positioning eccentric wheel (16) in transmission shaft (13)；The present invention is that the eccentric distance for doing circle rotation movement while generation using driving device driving eccentric further drives spool to do straight-line displacement movement, and then realizes that reversal valve quickly commutates.
Description
Technical field：
The present invention relates to mechanical, hydraulic, pneumatically and electrical engineering field, filled in particular to a kind of eccentric drive reversal valve
It sets.
Background technique：
Existing reversal valve driving method is roughly divided into three kinds：1, manual 2, switching value solenoid actuated 3, analog quantity ratio
Servo magnet driving.Manual actuation reversal valve the degree of automation is low, is not suitable for the control of industrial automation occasion；Switching value electromagnetism
Iron drives reversal valve electrical response time long, is not suitable for quick response and industrializes occasion demand；Analog quantity proportional servo electromagnet
Reversal valve fast response time is driven, but manufacturing cost is high, the order cycle time is long, maintenance is inconvenient, contamination resistance is poor, and arrives mesh
Before until such valve 90% or rely on import.
Summary of the invention：
It is an object of that present invention to provide a kind of eccentric drive change valve device, this device, which is furnished with, accurately controls driving device
Frequency, revolving speed, angle and torque drive set controller, and then displacement sensor can be passed through and realize commutation response valve
The stepless time adjustment of frequency.When reversal valve quick acting, connected using the characteristic band movable eccentric wheel of driving device contiguous circumferential movement
Continuous rotation；Eccentric wheel continuous rotation generates continuous eccentric distance in turn；The continuous eccentric distance band movable valve plug that eccentric wheel generates
Generate continuous straight-line displacement variation；It is final to realize that reversal valve quickly commutates.
Detailed description of the invention：
Attached drawing is constituted part of this application for a further understanding of the present invention, illustrative example of the invention and its
Explanation is used to explain the present invention, and is not constituted improper limitations of the present invention.In attached drawing：
Fig. 1 is the structural schematic diagram of present example eccentric drive change valve device.
Specific embodiment：
Example of the invention is described in detail below in conjunction with attached drawing, but the present invention can be defined by the claims and
The multitude of different ways of covering is implemented.
As shown in Figure 1
1, drive set controller (11) is connect by power cable and communication cable with driving device (10), is reached and is opened
Purpose that is dynamic, stopping and accurately control driving device.
2, driving device (10) and transmission shaft (13) are same by driving device shaft coupling (12) and transmission shaft shaft coupling (14)
The connection of the heart.
3, by equipped with square key pin (19) transmission shaft (13) keyway position and eccentric wheel (15) keyway position be aligned through and incite somebody to action
Eccentric wheel (15) is adjusted to predeterminated position；Further by a left side for eccentric wheel positioning sleeve (16) and (161) dress and eccentric wheel (15)
Right two sides, to achieve the purpose that change in location does not occur mutually in rotary course for transmission shaft (13) and eccentric wheel (15).
4, bearing (17) and bearing (171) fill and the left and right sides bearing position of transmission shaft (13), further difference respectively
Dress and bearing block (18) and bearing block (181).
5, spool (31) dress and valve body (30) inner hole；Spool (31) is equipped with the reset bullet of spool (31) by proximal cover (34) side
Spring (32)；Spool (31) is close to go side lid (33) side end equipped with promotion bearing (35)；Pin shaft (36) dress with spool (31) and push away
Dynamic bearing (35) inner hole；Closed position sensor (20) and open position sensor (21) is respectively set in eccentric wheel (16) two sides.
6, when spool (31) needs to do closing motion, drive set controller (11) passes through power cable and communication cable
Driving device (10) rotation is controlled, and then is rotated with movable eccentric wheel (15), when closed position sensor (20) detects eccentric wheel
(15) when raised position, drive set controller (11) stops power output；And then driving device (10) stops operating；It is eccentric
Wheel (15) is simultaneously stopped rotation；At this point, spool (31) is in closing motion output state.
7, when spool (31) needs to do opening action, drive set controller (11) passes through power cable and communication cable
Driving device (10) rotation is controlled, and then is rotated with movable eccentric wheel (15), when open position sensor (21) detects eccentric wheel
(15) when raised position, drive set controller (11) stops power output；And then driving device (10) stops operating；It is eccentric
Wheel (15) is simultaneously stopped rotation；At this point, spool (31) is in opening action output state.
8, when needing rapid succession to act, the characteristic of driving device (10) driving transmission shaft (13) continuous rotation is utilized
Band movable eccentric wheel continuous rotation；Eccentric wheel continuous rotation generates continuous eccentric distance in turn；The continuous bias that eccentric wheel generates
Distance band movable valve plug generates continuous straight-line displacement variation；It is final to realize that reversal valve quickly commutates.
9, it is learnt from foregoing description, this eccentric drive change valve device is not only suitable for the control of industrial automation occasion, and has
There is the characteristic of fast response time, and has both that structure is simple, easy to maintain, contamination resistance is strong, is intuitively easy to judge that failure etc. is excellent
Point.
10, it the foregoing is merely preferred embodiment of the invention, is not intended to restrict the invention, for those skilled in the art
For, the invention may be variously modified and varied.Any modification for all within the spirits and principles of the present invention, being made, etc.
With replacement, improvement etc., should all be included in the protection scope of the present invention.
