Abstract
The utility model relates to an electric motor valve. A DC motor is arranged on a common valve, the top of a valve shaft of the valve is a rack bar which is integrated with the valve shaft, and the rack bar is meshed with a gear which is fixed on the motor; the gear is driven to rotate by the DC motor, so that a valve plug in the valve can be driven to open and close. The utility model with the structure has the advantages of simple whole structure, high safety for valves, labour saving and convenient operation. The utility model is suitable for various prepaying (IC card) gas meters, water meters and heat meters. The utility model can also be used in other automatic control systems with weak corrosion.
Description
The utility model relates to a kind of motor valve.
Being seen various valves all are manually " unlatchings " and " closing " at present, when this valve is used for automatic control system or is used for all types of prepayment (IC-card) gas meter, water meter and hotlist, seem very inconvenient, and are also inharmonious.
The purpose of this utility model is to provide a kind of motor valve that can be automatically controlled easy to use.
The purpose of this utility model is to realize like this, be that direct current generator is set on common valve, the valve shaft top of its common valve is to be the tooth bar of one with it, the tooth bar on this valve shaft top is meshed with gear on being fixed on motor, by the rotation of direct current generator actuation gear valve shaft is moved axially, thereby drive " unlatching ", " closing " of valve plug.
The utility model makes overall structure simple owing to adopt said structure, and the high safety of valve uses laborsaving convenience, is suitable for all types of prepayment (IC-card) gas meter, water meter and hotlists, also can be used in the automatic control system of other weak corrosion.
Provide specific embodiment below in conjunction with accompanying drawing, further specify the utility model and how to realize.
