Abstract
The utility model relates to an opening and closing mechanism of an electric stop valve, which is used for controlling a fluid pipeline, especially in a stop valve of a civil controllable gas meter. The opening and closing mechanism controls the position and the rotation of a planetary wheel (7), and can provide drive control for the opening and the closing of the valve. A one-way transmission mechanism is arranged between the planetary wheel (7) and a planetary pendulum (1), and an elastic spacer device of the planetary pendulum is arranged between the planetary pendulum (1) and a frame (13). The mechanism has the advantages of simple structure, easy realization, short action time and no large power and large impact torsion in the running process, and the utility model provides the condition for an instant power supply valve, and provides accurate drive for an electric stop valve.
Description
Technical field
The utility model relates to the opening/closing mechanism of the Electric Actuated Stop Valves in the controlled gas meter of opening/closing mechanism, particularly family expenses of the valve in the gas pipeline control field.
Background technique
In combustion gas control field, particularly the controlled gas meter of family expenses needs low power consumption, and is simple in structure, and it is reliable to go slick, and the life-span is long, and the moment power supply can be closed the Electric Actuated Stop Valves of valve.The opening/closing mechanism of existing known Electric Actuated Stop Valves has thread transmission, and the subject matter of this kind mechanism is that stall impacts the big power consumption that causes and high pulling torque and impacts following member damage and sensitivity and poor reliability.
Summary of the invention
The utility model is for solving the big power consumption of known mortor operated valve, and the member that high pulling torque causes damages; The problem of poor sensitivity provides a kind of opening/closing mechanism of Electric Actuated Stop Valves.This opening/closing mechanism is simple in structure, and is highly sensitive, reliable, easily realizes, drives for Electric Actuated Stop Valves provides to open and close accurately.
For achieving the above object, the Electric Actuated Stop Valves opening/closing mechanism of the utility model design has with the driving gear of rotating shaft location and coaxial planet pendulum.Driving gear and planet wheel engagement.The planet wheel concentric is fixed on the axle, it is characterized in that forming unidirectional wedging mechanism, or above-mentioned wedging mechanism is set between driving gear and planet are put in the wedge dish structure that the wedge pawl of coaxial tightening on ratchet mechanism being set or being provided with by the axle of planet wheel between the axle of planet wheel and the planet pendulum and planet are laid out the cylinder with projection structure.In addition, also between above-mentioned planet pendulum and frame, the elastic limit device that the elastic arm that has the projection structure on the concave structure of planet pendulum and the frame is formed is set, or only lays out elastic structure is set at planet.
In the utility model, driving gear is the output gear of micro motor retarder.When it rotates by the direction of opening stop valve, drive the planet wheel rotation.Planet wheel drives the driving link of ratchet mechanism simultaneously or drives the member wedge pawl of unidirectional wedging mechanism, and drives the planet pendulum with driven member simultaneously and enter and open the stop valve position, drives valve.Ratchet mechanism or unidirectional wedging mechanism are unidirectional sliding mode in this process.When driving gear by closing stop valve direction when rotation, planet wheel will be reversed stop.Driving gear just drives planet wheel and promotes the planet pendulum by the link of planet wheel again and rotate around the axis like this, is separated from valve position up to planet wheel, enters and closes valve position.
Above-mentioned two process micro motors are short time work, so very power saving.And working procedure does not have the impact of powerful high pulling torque, and mechanism is difficult for producing damage, and reliability improves, and action is also very accurately sensitive.When being arranged between planet pendulum and the driving gear, unidirectional wedging mechanism has identical result.
In the utility model, lobed structure on the cylinder of wedge dish structure.In common mechanical transmission, rely on the unidirectional transmission of voussoir mainly to be used in the transmission of higher speed, its dependence be the friction force of storeroom.And in the low speed transmission, use self lubricity better, and during the more weak material of rigidity, the reliability of its transmission is just relatively poor.The protruding structure of cylinder increase for wedge dish structure has increased the transmission stiffness after the wedging in the case, thereby guarantees the reliability of low speed transmission.
In the utility model, between frame and planet pendulum, be provided with the elastic limit device of planet pendulum, planet wheel is when driving valve position, and this device also enters spacing position.Can prevent the change of planet pendulum activation point when being subjected to the accidental shock vibration like this, thereby make transmission more reliable.
Description of drawings
Fig. 1 is the utility model unidirectional wedging of employing mechanism between planet wheel and planet pendulum, the structural representation when being in out valve position in mechanism.
Fig. 2 is the D-D face figure of Fig. 1, and elastic arm l2 does not draw among the figure
Embodiment
Embodiment is described as follows in conjunction with the accompanying drawings:
When the opening/closing mechanism of the utility model Electric Actuated Stop Valves adopts unidirectional wedging mechanism between planet wheel and planet pendulum, the wedge dish structure 9 that has the cylinder of bumps formation 2 on the planet pendulum 1 matches with wedge pawl 3 concentrics, wedge pawl 3 and the planet wheel 7 coaxial axles 6 that are fixed in, planet wheel 7 is meshed with driving gear 4.In the drawings, when driving gear 4 during by the rotation of arrow A direction, planet wheel 7 is by the rotation of arrow B direction, and drives wedge pawl 3 simultaneously and rotate by the arrow B direction.At this moment, be in the slide relative of forward between wedge pawl 3 and the wedge dish structure 9, planet wheel drives planet pendulum 1 by axle 6 simultaneously, is the center with rotating shaft 5, and the direction rotation by arrow A enters diagram up to planet wheel and drives valve position.At this moment, the elastic limit device to planet pendulum 1 enters spacing position between frame 13 and the planet pendulum 1.
When driving gear 4 was pressed the opposite direction driving of arrow A, planet wheel 7 was promoted by the opposite direction by arrow B.Planet wheel 7 drives axle 6 simultaneously, and axle 6 drives wedge pawl 3, makes wedge pawl 3 and wedge dish structure 9 form the braking of reverse wedging.So with respect to driving gear 4, all members on the Transmitted chains of above-mentioned reverse direction actuation all do not have motion.And all with the counter-rotation of driving gear 4 by arrow A.Thereby being separated from valve position enters and closes valve position.
