Technical field
The utility model relates to a kind of travel control switch, is specifically related to a kind of for regulating the journey controller that limits pneumatic valve open and close stroke.
Background technique
At present, it is all to adopt power supply stroke sensitive switch control solenoid valve or motor to realize usually that existing valvular open and close stroke adjustment limits, this electronic journey controller is subjected to power limitations, can't meet the need of work without pneumatic valve open and close stroke limit under condition of supplying power.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of simple in structure, reliable performance, debugging is convenient and be not subjected to the pneumatic valve journey controller of power limitations.
for achieving the above object, the utility model provides a kind of journey controller of pneumatic valve, comprise counter and limited valve, wherein said limited valve consists of limiting piston and limited valve valve body, offer suction port and the air outlet that is interconnected on described limited valve valve body, described suction port is connected with external air source, described air outlet joins with the pneumatic motor that is used for the unlatching of driving pneumatic valve, the two ends of described counter are connected with respectively input shaft and output shaft, and the interlock between described input shaft and output shaft is controlled by rolling counters forward, be equiped with on described input shaft with pneumatic valve and open the input gearwheel that gear is meshed and links, described output shaft and limiting piston one end are affixed, the other end of described limiting piston is arranged in the limited valve valve body, offer a piston hole on the described limiting piston that is positioned at the limited valve valve body, and described piston hole can be by described limiting piston turning in the limited valve valve body, keep switching on or off with suction port and air outlet on the limited valve valve body.
the beneficial effects of the utility model are: adopt said structure, first counter is debugged before use, debugging complete rear pneumatic valve opens, suction port on the limited valve valve body and air outlet keep being communicated with at this moment, thereby making described pneumatic motor can drive pneumatic valve opens, the pneumatic valve unlatching is opened gear by pneumatic valve will be with the driven input shaft rotation with the engagement interlock of input gearwheel, and through rolling counters forward, when counter reaches the predefined number of turns or position, to drive output shaft rotation 90 degree, thereby make described limiting piston Rotation With Changing to, and then make described limiting piston cut off being connected of suction port and air outlet on described limited valve valve body, on the limited valve valve body without source of the gas, pneumatic motor will quit work, thereby realize opening pneumatic valve, closing stroke controls spacing.In sum, the utility model provides a kind of simple in structure, reliable performance, debugging is convenient and be not subjected to the pneumatic valve journey controller of power limitations.
The utility model can further be set to described input gearwheel and be installed on input shaft by Cock screw.Adopt said structure, can guarantee effectively that described input gearwheel can be installed on input shaft reliably.
The utility model also can further be set to also be equiped with seal ring between described limiting piston and limited valve valve body.Adopt said structure, seal ring is set can makes between described limited valve valve body and limiting piston tightness better.
