Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, be further detailed:
Fig. 1 is that system of the present utility model forms schematic diagram.
Embodiment
The main mate gear formula of the utility model valve is used, so-called gear type valve is a kind of valve that utilizes gear to rotate to drive valve opening closure, during work, gear drives rotation by motor, the associated components meshing with gear after gear rotates can be done displacement, and the on-off structure of valve is fixed on these parts just and can transfers the keying that realizes valve by control gear positive and negative.Feature of maximum of said gear formula valve is that its on-off structure can keep automatically after valve control puts in place, even if motor is stopped power supply, the state of valve can not change yet, and only has valve when motor reversal just can reset thereupon.The concrete principle that the utility model is realized is that motor can produce an instantaneous high electric current while being blocked, and this instantaneous high electric current can be indicated the state that puts in place of valve.
With reference to Fig. 1, valve recloser of the present utility model is mainly comprised of power subsystem 1, switching unit 2, electric motor units 3, current limliting unit 4 and storage capacitor unit 5.The concrete effect that above-mentioned each unit matching work will reach is to make electric motor units 3 to drive valve event in the mode of forward, stop power supply, and electric motor units drives valve reset in the mode of overturning when having a power failure after valve puts in place.
Wherein, power subsystem 1 is for power supply.When the first path disconnecting when conducting when switching unit 2 has the energising of switching controls end, switching controls end and power-off, the energising of switching controls end, disconnect and the alternate path of conducting during power-off, this switching unit 2 can utilize the concrete structures such as relay to realize.Electric motor units 3 moves for control valve, it is provided with the first input end being connected with the first path and the second input end being connected with alternate path, electric motor units has forward in the situation of input in first input end, have in the situation of input reverse in the second input end.Current limliting unit 4 input ends are connected with power subsystem 1, and output terminal is connected with the first path, and when the electric current of output is greater than predefined value, current limliting unit 4 stops output, and the current limliting unit with this function can utilize various available circuit structures to realize, and at this, is not repeating.The input end of storage capacitor unit 5 is connected with power subsystem 1, and output terminal is connected with alternate path, and particularly, storage capacitor unit 5 can directly be connected with power subsystem 1, also can connect the output of current limliting unit 4, by 4 power takings of current limliting unit.Power subsystem 1 or current limliting unit 4 are provided with the control delivery outlet of the switching controls end that is connected to switching unit 2.
Drive power subsystem 1 while starting to power to electric motor units 3 by the first path of current limliting unit 4, switching unit 2, switching unit 2 keeps the first path conducting under the control of power subsystem 1 or current limliting unit 4, under this working state, the required electric current of electric motor units 3 work is less than the predefined value of current limliting unit 4.After valve puts in place, electric motor units 3 is plugged, and produces transient high-current, and current limliting unit 4 can stop output after this transient high-current being detected, and electric motor units 3 quits work, and valve state keeps.In said process, storage capacitor unit 5 is full of electricity.When power subsystem 1 has a power failure output, switching unit 2 actions, the first path cuts off, alternate path conducting, storage capacitor unit 5 provides the work energy of reversion to electric motor units 3, and electric motor units 3 actions, drive valve reset.
From said process, in the utility model, the predefined value of current limliting unit 4 is with electric motor units 3 parameter correlations of concrete use, need to be configured according to different electric motor units.
