Model utility content
The purpose of this utility model is defect for prior art and deficiency, provide a kind of simple and reasonable, easy to assembly, manufacture cost is lower, volume arrange less, transmission efficiency is higher, the good novel gas meter motor valve in labor-saving effect.
For achieving the above object, the utility model is by the following technical solutions:
Novel gas meter motor valve described in the utility model, comprise valve body, be arranged at the screw rod in described valve body, be arranged at the motor cabinet on described valve body and gearbox, described valve body is provided with gas port, one end of described screw rod is provided with the sealing gasket matched with described gas port, described sealing gasket coordinates with described screw drive, motor is provided with in described motor cabinet, the output shaft of described motor is provided with driving gear, mounting plate is provided with in described gearbox, the other end of described screw rod is rotatably arranged on described mounting plate, described screw rod is provided with rotating disk, described rotating disk is provided with internal gear, described internal gear and described driving gear are connected with a joggle.
Further, transmission nut is provided with between described sealing gasket and described screw rod.
Further, the bottom of described sealing gasket is provided with seal closure, and described seal closure covers at the outside of described screw rod, and the end of described seal closure and described mounting plate are sealed and matched.
Further, the top of described sealing gasket is provided with elasticity projection straight up.
The beneficial effects of the utility model are: the utility model by arranging rotating disk on screw rod, rotating disk is arranged the internal gear be connected with a joggle with driving gear, during work, motor drives internal gear to rotate by driving gear, internal gear passes through rotating disk drive screw turns while rotation, and then reach the effect controlling sealing gasket motion, with adopt the first driven gear in prior art, second driving gear and the second driven gear are compared, driving mechanism vibrational power flow of the present utility model is more simple, easy to assembly, reduce manufacture cost, effectively reduce intermediate energy loss, transmission efficiency is higher, labor-saving effect is better, and, the utility model volume is also made to arrange more compact, effectively save installing space.
