The electric resilient gate valve has the features such as quickness,liableness and easy installation etc..It is widely used in tap water industry,sewage treatmen, shipping,construction,petroleum,chemicals,food,pharmacy,textile,electric power,metallurgy and energy system's pipeline to adjust and shut off fluid.
Accessory selection must be evaluated for its capability to transmit the required torque requirements to the valve. Resilient seated gate valve is equipped with all kinds of electric actuator to clients' requirements to realize long-distance control and automatic control. When an electric current is passed through a wire loop that is in a magnetic field, the loop will rotate and the rotating motion is transmitted to a shaft, providing useful mechanical work. The traditional electric motor consists of a conducting loop that is mounted on a rotatable shaft. Current feed in by carbon blocks, called brushes, enters the loop through two slip rings. The magnetic field around the loop, supplied by an iron core field magnet, causes the loop to turn when current is flowing through it. In an alternating current (AC) motor, the current flowing in the loop is synchronized to reverse direction at the moment when the plane of the loop is perpendicular to the magnetic field and there is no magnetic force exerted on the loop. Because the momentum of the loop carries it around until the current is again supplied, continuous motion results. In alternating current induction motors the current passing through the loop does not come from an external source but is induced as the loop passes through the magnetic field. In a direct current (DC) motor, a device known as a split ring commutator switches the direction of the current each half rotation to maintain the same direction of motion of the shaft. In any motor the stationary parts constitute the stator, and the assembly carrying the loops is called the rotor, or armature. As it is easy to control the speed of direct-current motors by varying the field or armature voltage, these are used where speed control is necessary.
