Electrical ball valve

Abstract

This electrically operated ball valve belongs to the valve domain, specially designs one kind to be able through the electronic installation realization automatic control valve. This electrically operated ball valve including the valve body, the valve lever and the valve core, the valve core is located valve in vivo, the valve lever passed through the valve body, its inner end and the valve core connect, the valve lever outside end is equipped with together the back plate, a gear and an electrical machinery, back plate and the gear and the gear and the valve lever outside end solid company, the back plate uses in to limit the valve lever the rotation angle, on electrical machinery fixed Yu Fati, between the electrical machinery revolution axis and the above gear is equipped with the gear cluster, the gear cluster separately to the electrical machinery revolution axis, the tooth lines on the feet and palms of buddha meshes. Using the electrical machinery rotation, and lies in the structure through the ball valve merit extremely reasonably, the product has a better stability in the use process, also is not easy to wear, can lengthen the service life, has the remarkable energy conservation effect.

Description

technical field [0001] The invention belongs to the field of valves, in particular to a valve capable of automatic control through an electronic device. Background technique [0002] In the automatic control system of the central air conditioner, the temperature control is generally realized by the solenoid valve, that is, the conduction and closure of the pipeline are controlled by the solenoid valve. Since the solenoid valve uses the principle of electromagnetic induction, the driving force generated is small, the closing is unreliable, and it is prone to jamming, etc., making the valve unable to close freely, resulting in the failure of the entire control system to operate normally. [0003] Chinese patent 992572940 provides a kind of "electric valve", which is composed of upper and lower housings, motors, crankshafts, pulleys, push rod mechanisms, bimetallic plates, etc. The valve composition. The electric valve is driven by a motor, the power is ...
