Summary of the invention
The utility model to solve current fuel gas motor valve motor and combustion gas packing bad, the problem that easily causes motor to be corroded reduction of service life, a kind of gas intelligent motor valve driving mechanism of the present utility model is provided for this reason, in this driving mechanism, between motor and combustion gas, packing is reliable for effect, motor is not subject to exhaust gas corrosion, and this driving mechanism also has simply constructed feature.
For addressing the above problem, the technical solution adopted in the utility model is to have motor housing, in motor housing, be provided with motor, on motor housing, be connected with reduction gear box, be provided with train of reduction gears in reduction gear box, the output gear of motor coordinates with train of reduction gears, its special way is to be provided with stuffing box gland between described motor and the cavity of reduction gear box, sealing cover has axial hole, and this axial hole of stuffing box gland is placed on motor shaft, and the upper choma of stuffing box gland axial hole is sealed and closed in motor shaft perisporium.
Described stuffing box gland lower edge should have the radially sealing clamping ring of extension, and sealing trim ring is pressed on above the axial electric machine casing of described motor.
The utility model preferably described sealing is connected with the transition ring that inwardly prolong in footpath above being placed on the inner edge place of described sealing clamping ring, and transition ring inner edge is connected with and upwards extends and the taper ring of convergent radially, and the suitable for reading of described axial hole is the upper port of this taper ring.
More preferably described motor housing and reduction gear box are bolted, and reduction gear box bottom center hole lower edge is provided with step state recess, and the bottom surface envelope of this step-like recess is pressed on the sealing clamping ring of described stuffing box gland.
Described train of reduction gears can have a gear, No. two gears and No. three gears, the input gear ring of a gear engages with the output gear of described motor, the output gear of a gear engages with the input gear ring of No. two gears, and the output gear of No. two gears engages with the input gear ring of No. three gears.
This reality has the stuffing box gland in type should adopt rubber material to make.
The utility model is owing to being provided with stuffing box gland between motor and the cavity of reduction gear box, the axial hole of stuffing box gland is set in motor shaft, the upper choma of axial hole is sealed and is closed in motor shaft perisporium, try out and show that stuffing box gland neither affects motor shaft and rotates (motor shaft side face is fully smooth and the diameter of axle is relatively little), can efficiently isolate again the outer gas of axle, make motor and extraneous combustion gas packing good, avoid motor to be subject to exhaust gas corrosion, thereby extend the working life of motor and whole valve; The utility model also has simply constructed feature.
