Abstract
The utility model relates to a switch valve driven by electric power in the field of the general-purpose mechanism. The valve is composed of a manual and electric automatic switching mechanism and an electrodeless adjust torque limitation mechanism. The manual and electric automatic switching mechanism exchanges the valve driven by electric power from the electric operation to the manual operation or exchanges the valve driven by electric power from the manual operation to the electric operation. The electrodeless adjust torque limitation mechanism makes the output torque of the valve driven by electric power make electrodeless adjustment in the required number value via a trimming screw nail. The switching degree of sensitivity of the utility model is 100%, and the valve driven by electric power has the advantages of remissive intensity of labor and convenient adjustment.
Description
The utility model is the Electric actuator that belongs to universal machine field switch valve.
The Electric actuator of existing switch valve has following several:
(1) switches to manual operation from electronic, wipe operation, wiping is pulled out in rotation, pull out to wipe and stir clutch, itself and claw on the worm gear are broken away from mesh, and mesh with the manual clutch claw by removing with removing drive pulled out.At this moment rotate handwheel and can realize the hand switch valve, this switching mechanism need be removed switching in hand control.
(2) become electronic operation from manual switchover.During the motor switch valve, worm gear rotates group support plate that smears is struck the beam, and at this moment pressure spring promotes the claw engagement on interposed clutch and the worm gear, drives the clutch rotation when worm gear rotates, clutch drives output shaft and rotates, and reaches the purpose of motor switch valve.Switch to automatic switchover during this electronic work, must manual switching.Therefore the moving handoff procedure of above torch is referred to as semi-automatic switching in electric device for valve.
(3) torque limit mechanism stirs resistance arm by power arm and makes itself and switch contact leave outage.This structure makes switch contact be in atmospheric pressure state, influences switch working life.When putting, the number of adjustment torque also adjusts with the screw left rotation and right rotation.
When (4) adjusting torque numerical value also useful cam is adjusted, and the torque value of its adjustment is a jump type
The purpose of this utility model provides the electric device for valve that the moving mechanism for automatically switching of a kind of torch and stepless adjustment torque limit mechanism form.Need not remove and wipe reaching to dial.And utilize electromagnetic chuck and pressure spring.Make clutch pawl and electromagnetic chuck adhesive or disengaging.Torque limit mechanism has adopted stepless adjustment torque limit mechanism, by the left rotation and right rotation micrometer adjusting screw, makes torque value can carry out stepless adjustment in the number that requires is put, and utilizes torque to come the control valve open and close.
The utility model major technique feature: this electric device for valve is made of the moving mechanism for automatically switching of torch and stepless adjustment torque limit mechanism etc.; Torch moving mechanism for automatically switching is by handwheel (1), manual gear (2), spline tooth wheel shaft (3), electromagnetic chuck (4), pressure spring (5), clutch pawl (6), driving pawl (7), worm screw (8), worm gear (9), motor (10), housing (28), screw (29), hand wheel shaft (30) constitutes, its each transmission part Placement: handwheel (1) is connected for strand with hand wheel shaft (30), hand wheel shaft (30) is connected for singly-bound with manual gear (2), manual gear (2) is an Involutes Gears Transmission with spline tooth wheel shaft (3), spline tooth wheel shaft (3) is contained in the axis hole of electromagnetic chuck (4), electromagnetic chuck (4) is fixed on the housing (28) by screw (29), pressure spring (5) one ends lean against on the end face of electromagnetic chuck (4), and the other end leans against on the end face of clutch pawl (6).Clutch pawl (6) and spline tooth wheel shaft (3) be for free-sliding spline is connected, with driving pawl (7) be castellated being connected with a joggle, driving pawl (7) is connected for free-sliding spline with worm screw (8).Drive worm screw (8) by motor (10), worm gear (9) rotates.
Torch moves mechanism for automatically switching, can replace manually switching, and during electronic work, electromagnetic chuck gets electric, and the clutch pawl is sucked near electromagnetic disc one end, clutch pawl and driving pawl is broken away from mesh, thereby realize the electronic valve that opens or closes.When needs hand switch valve, electromagnetic chuck loses suction owing to be in off-position, and at this moment the clutch pawl with the driving pawl engagement, at this moment rotates handwheel and can realize manually opening or closing valve under the promotion of pressure spring.
