A special actuator for on-off controller

Abstract

The invention discloses an actuator special for an on-off controller. The actuator special for the on-off controller comprises a circuit execution control and a valve body, wherein the circuit execution control comprises a driving motor, a driving wheel, a gear case, a control circuit board and a control wire, and the valve body comprises a valve rod, an O-ring seal, a spherical arc surface sealing layer and a valve element. The actuator special for the on-off controller is characterized in that a valve opening optoelectronic switch, a valve closing optoelectronic switch, a light-shading turntable and a light-shading plate are arranged in the circuit execution control, the light-shading plate is driven to move by the light-shading turntable to detect whether the rotation stroke of the driving motor is in place, outer threads are arranged at the two ends of the valve body, the outer threads are connected with a standard meter connector in a matched mode, technological parameters of a mould for manufacturing the valve body are reasonably adjusted, the sealing contact pressure between the spherical arc surface sealing layer and the valve element in the valve body is controlled, the working medium of the valve element is water, the starting torque under the working pressure of 1.6MP is smaller than 0.1N.m, and the service life of the driving motor and the service life of a gear set are larger than 100 thousand times.

Description

technical field [0001] The invention relates to the on-off (opening and closing) control of the heating pipeline for heat supply metering and heat supply regulation, in particular to a special actuator (electric ball valve) for the on-off controller. This special actuator is mainly suitable for on-off time area method heat metering system. Background technique [0002] At present, reducing building energy consumption has become an important part of my country's energy structure adjustment. As an important measure to promote the strategy of sustainable energy development, building energy conservation includes adopting a series of energy conservation measures and energy management methods. Central heating, as an essential measure for heating in winter in northern China, accounts for a relatively large proportion of building energy consumption. Especially in areas where the current air quality is worrying, heating is one of the main culprits of urban atmospheric smog, and how...
