Abstract
The utility model provides a novel electric actuator suitable in a building hot water supply system, the electric actuator is especially suitable in a heating system, and the electric actuator belongs to the technical field of water heating equipment manufacturing. A normal electric actuator cannot cut off power after execution motion is completed, electricity is wasted, the problem is solved by the novel electric actuator, and when power failure happens to a circuit, automatic start of the electric actuator is simultaneously guaranteed, normal heat supply and heating requirements of residents can be ensured, and the electric actuator is simple in structure, reliable in work and low in cost.
Description
Technical field
A kind of New Electric Actuating is applicable to the building hot water supply system, and particularly suitable is applicable in heating system, belongs to plumbing equipment manufacturing technology field.
Background technique
Along with the improvement gradually of living standards of the people, the hot-water supply system has generally been adopted in many residential quarters, has generally adopted heat supply heating system in the north, and all heat supply heating systems have all changed resident's quality of life.The control actuator of existing heat supply heating system all adopts two kinds of electrical actuator or electric actuator, after this actuator has actuator's action and completes, can't cut off the power supply, and causes the waste of electric energy.In order to overcome the defective of waste of energy, some producers have developed the electric actuator of pulsed, although this electric actuator has solved the outage problem after electric actuator is completed execution action, but when electric actuator during at the state of closing, after circuit cuts off the power supply, electric actuator can't be opened, possible moulding pipeline temperature is too low, can't guarantee to the requirement of resident's heat supply heating.The utility model provides a kind of outage problem that both can solve after electric actuator is completed execution action, can realize again guaranteeing the electric actuator that electric actuator can be opened when circuit occur to have a power failure, that this electric actuator has is simple in structure, reliable operation, cheap characteristics.
The model utility content
The purpose of this utility model: in order to overcome the drawback of can't cutting off the power supply after general electric actuator is completed execution action, the utility model provides a kind of New Electric Actuating, both overcome general electric actuator and completed the drawback of the waste electric energy that can't cut off the power supply after execution action, guarantee simultaneously when circuit occurs to have a power failure, the electric actuator of automatically electric actuator being opened, that this electric actuator has is simple in structure, reliable operation, cheap characteristics.
The technological scheme that its technical problem that solves the utility model adopts is: general electric actuator is comprised of electronic, actuator and control gear, it is characterized in that: large bulk capacitance is equipped with in central authorities in the electric actuator enclosure, one end of large bulk capacitance is connected with the output terminal of the temperature controller of outside, the other end is connected with the input end that is arranged on electric controller enclosure motor, another terminal of motor are connected output terminal and are connected with temperature controller, on the rotor of motor, actuator is housed, the lower end of actuator is connected with valve rod.
It is identical that large bulk capacitance in the utility model is arranged on the effect that temperature controller neutralization is arranged in electric actuator, can reduce like this volume of electric actuator.
The beneficial effects of the utility model are: after electric actuator is completed execution action, utilize the characteristic of capacitor charging, power supply with motor disconnects automatically, the electric weight that can utilize again electric capacity to store, when running into down circuitry, automatically electric actuator is opened, guaranteed the demand of resident's heat supply heating.

Embodiment
center of inside at valve body (1) is equipped with sealing gasket (10), valve gap (2) is equipped with in the upper end of valve body, the center of inside of valve gap (2) is equipped with Returnning spring (9), the upper end of Returnning spring (9) is connected with valve rod (8), the center that Returnning spring (9) is passed in the lower end of valve rod (8) is connected with the inner sealing gasket (10) of valve body (1), the bottom of the shell (6) of the upper end of valve gap (2) and electric actuator is connected, center of inside at the shell (6) of electric actuator is equipped with actuator (4), the lower end of actuator (4) is connected with valve rod (8), the upper end of actuator (4) is connected 7 with motor) rotor connect, one end of motor (7) circuit input is connected 5 with large bulk capacitance)-connection of utmost point tenminal block, the other end of motor (7) circuit input is connected 3 with temperature controller) the ground terminal of output terminal connect, the output terminal of temperature controller (3)+terminal connection large bulk capacitance+utmost point tenminal block.
working principle, after temperature controller (3) sends the throttle down instruction, relay in temperature controller (3) power up make large bulk capacitance (5)+utmost point and temperature-controlled area+utmost point connects, electric current is connected motor (7) by large bulk capacitance (5), motor (7) entry into service, large bulk capacitance begins charging, the rotor rotation driving mechanism (4) of motor (7), make actuator (4) promote valve rod (8) downwards, valve rod (8) drives sealing gasket (10) and moves down, valve closing, after the large bulk capacitance charging finishes, cut off automatically the electric current of motor, make circuit be in open-circuit condition, when temperature controller (3) sends Open valve instruction or circuit power failure, relay outage in temperature controller (3), large bulk capacitance (5)+utmost point and temperature controller-utmost point tenminal block connects, large bulk capacitance+utmost point by temperature controller-utmost point tenminal block and motor (7)-utmost point connects, motor (7) begins counter-rotating, the anti-phase rotation driving mechanism of rotor (4) of motor (7), actuator (4) is moved up, valve rod (8) moves up under the promotion of Returnning spring (9), valve rod (8) drives sealing gasket (10) and moves up, valve opening, after the large bulk capacitance discharge finishes, motor shuts down.
Claims (2)
1. New Electric Actuating, general electric actuator is comprised of electric actuator and control gear, it is characterized in that: large bulk capacitance is equipped with in central authorities in the electric actuator enclosure, one end of large bulk capacitance is connected with the output terminal of the temperature controller of outside, the other end is connected with the input end that is arranged on electric controller enclosure motor, on the rotor of motor, actuator is housed, the lower end of actuator is connected with valve rod.
