Description
Technical field
The present invention relates to a kind of self-locking device of electricity consumption magneto drive, particularly a kind of self-locking device that is applied in the solenoid valve.
Background technique
Existing solenoid valve must have rated current to pass through electromagnetic coil in the course of the work always, could guarantee its stable operation, if but time remaining in working order, not only expend more electric energy, but also very easily burn out electromagnetic coil, thereby cause the rate of fault height of many automatic control equipments, influence its normal use.Though the solenoid valve that has has locking device, it is in order to be to shield breaking down, and can not address the above problem.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned the deficiencies in the prior art, and a kind of self-locking device that is applied on the solenoid valve is provided, make solenoid valve can be stable during by electromagnetic coil at no current, work reliably, both saving power increased the service life again.
For achieving the above object, the technical solution adopted in the present invention is: a kind of solenoid valve self-locking device, has a columnar guide pipe, the outside of guide pipe is equipped with electromagnetic coil, cylindrical outer cover is equipped with in the outside of electromagnetic coil, the armature that can move up and down is installed in guide pipe, be installed with positioning pipe in the guide pipe upper end, the bottom of positioning pipe is equipped with refutes a device, refuting device top has the precession positioning work piece that is contained in positioning pipe top, refutes a device and the precession positioning work piece all can slide up and down in positioning pipe.Armature has axial circular hole with the center of refuting a device, be equipped with in the circular hole and can and refute a pull bar of device relative movement with armature, fixedly connected with the precession positioning work piece in the pull bar upper end, the lower end of pull bar is stretched out outer cover and is connected with load, at pull bar (3) a spacing card that limits the armature extreme lower position is housed.Release spring is housed refuting between a device and the precession positioning work piece, equidistantly be distributed with three dark locating slots and three shallow locating slots in the upper end of positioning pipe, dark locating slot and shallow locating slot are provided with at interval, periphery at the precession positioning work piece equidistantly is distributed with three location cards that cooperate with above-mentioned locating slot, the lower end of precession positioning work piece is evenly distributed with six leg-of-mutton commutating tooths, the tooth of refuting that the upper end of refuting a device is also equidistantly distributing six and matching with above-mentioned commutating tooth.
Aforesaid solenoid valve self-locking device also is equipped with damping spring between precession positioning work piece and outer cover end face.
The working principle of solenoid valve self-locking device of the present invention is as follows: when static, the electromagnetic coil outage, the location card landing of precession positioning work piece is fixed the position of pull bar in locating slot (deep trouth or shallow slot), makes load be in a position of determining in vertical direction; In the time of dynamically, electromagnetic coil energising attracts armature to move upward along pull bar, promotes to refute a device upwards and force the precession positioning work piece to leave locating slot, precession is finished at 60 ° of angles of rotation when the precession positioning work piece is being moved upward; After this, the electromagnetic coil outage, armature and precession positioning work piece reset under the acting in conjunction of gravity and release spring and damping spring, but because the precession positioning work piece rotates, thereby be bound to landing in the locating slot (shallow slot or deep trouth) of another height, thereby pull bar and load position in vertical direction thereof have been changed.
Therefore, solenoid valve self-locking device of the present invention can directly apply in the solenoid valve, make solenoid valve when being in the long-term stable operation state, no longer need electric current to flow through electromagnetic coil, keep work and replace the mechanical caging mode, only when changing working state, just there is the impulsive current of moment to flow through coil, thereby not only saved electric energy, noise when having eliminated the solenoid valve working state, and electromagnetic coil is long because of current"on"time in the course of the work thoroughly to have solved solenoid valve, overheated and, improved the stability and the reliability of its work by the phenomenon of being burnt, prolong service life of equipment.
