Embodiment Construction

[0011] see Figure 1-Figure 3 , an overrunning motor valve with automatic engagement and disengagement functions, which includes a motor 2 and a motor valve body 4, a driving gear 7 is mounted on the extension shaft of the motor 2, and a reduction mechanism and an overrunning mechanism are installed in the motor valve body 4 Type clutch mechanism, the rotation of the motor 2 is transmitted through gear meshing, and the motion is transmitted to the rack-shaped valve stem 17 through the deceleration of the deceleration mechanism to realize the opening action of the motor valve valve. The deceleration mechanism is a four-stage speed change structure, and its transmission mode is : The driving gear 7 drives the first-stage duplex gear 11, the first-stage duplex gear 11 drives the second-stage duplex gear 10, the second-stage duplex gear 10 drives the third-stage duplex gear 9, and the third-stage duplex gear The gear 9 drives the fourth-stage reduction gear 8, and the fourth-stage...

Abstract

An overdrive motor valve with automatic meshing and de-meshing functions comprises a motor and a motor valve body; a projecting shaft of the motor is equipped with a driving gear, the motor valve body is internally equipped with a decelerating mechanism and an overdrive clutch mechanism, the rotation of the motor is transmitted to a rack-shaped valve rod to realize the opening operation of the valve, the decelerating mechanism is a four grade speed varying mechanism, and the transmission manner is: driving gear->driving a first grade duplicate gear->a second duplicate gear->a third duplicate gear->a fourth duplicate gear->a gear and an overdrive ratchet gear, a plane cam and an intermediate gear to rotate, when the intermediate gear rotates to mesh with the duplicate gears, the intermediate gear drives the duplicate gears to rotate to ensure the rack-shaped valve rod to carry out displacement to integrate with a valve core which is internally sheathed with a tower-shaped spring and a rubber sealing jacket, the head of the valve core is embedded into valve petals and the closing operation of the valve can be realized by the elasticity of the tower-shaped spring. The invention can ensure the reliability and service life of the motor valve in use.

Description

technical field [0001] The invention relates to a motor valve, in particular to an overrunning motor valve mainly used on an IC card household membrane gas meter or a wireless membrane gas meter as a gas safety cut-off control valve. Background technique [0002] As a motor valve used on IC card household membrane gas meters, it is generally required that the valve switch be opened and closed quickly, sensitive and reliable, durable and power-saving. At present, the motor valves used on IC card household membrane gas meters or wireless membrane gas meters have mostly complex internal structures, high manufacturing costs, large power consumption, frequent failures, short service life and other disadvantages, which affect the safety of gas. Normal use. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects in the prior art, and provide an overrunning motor valve with automatic engagement and disengagement functions,...
