Description

Electric heating actuator

Technical Field

The utility model relates to a warm valve accessory that leads to, in particular to electric heat executor.

Background

The electrothermal actuator, also called electrothermal constant temperature controller, is a device with a new concept for remotely controlling system flow and heat (cold), and is suitable for heating of houses, markets and hotels, and temperature control and compartment temperature control of central air conditioners. The electric heating actuator is mainly used in a floor heating system and controls the closing and opening of a pipeline. The electric driving part is particularly applied to branch valves of water distributors, miniature valves and electric driving parts of electric heating actuators of dynamic balance valves. The work operation is noiseless, and the mounting means is connected to the nut, and is simple, the installation is rapid, and it is convenient to dismantle. The electric heating actuator consists of a temperature controller, a valve actuator and a valve. The thermostat is mounted on the wall of the room interior and is connected to the electro-thermal actuator by a cable, typically 100cm long, to connect the actuator to a selected control point (thermostat, programmer, timer or other remote device). The actuator is connected to the valve by a nut. When the indoor temperature reaches the temperature set by the temperature controller, the positive thermistor in the electric heating actuator starts to work, the heating thermal expansion device enables the valve to be closed, otherwise, the indoor temperature is reduced, the temperature controller is disconnected, the actuator is cooled, the expansion device is contracted, and the valve is opened. The general imported and domestic brands have the function of automatic power-off reset.

At present, foreign imported products can only be used as signal lines, cannot bear large current, can only be used for a linkage function (signal output has no current), and have large limitation in the application field. That is, the conventional product can only control one-to-one, and cannot control a plurality of devices individually. And when the traditional product is matched with other accessories, the traditional product is limited by the power supply voltage or the equipment voltage, and the traditional product is difficult to meet the existing use requirements.

Detailed Description

As shown in fig. 1-2, an electric heating actuator comprises a driving part 1 extending out of a mandril from the inside after being heated, a driven part 2 matched with the driving part 1 to perform linear reciprocating motion, and an upper connecting plate 3, wherein an upper contact 4 is arranged at the position of the upper connecting plate 3, a first wiring 7 connected with the upper contact 4 is led out of the upper connecting plate 3, a lower connecting plate 5 is arranged on the driven part 2, a lower contact 6 is arranged at the position of the lower connecting plate 5, a second wiring 8 connected with the lower contact 6 is led out of the lower connecting plate 5, and a local circuit is connected between the upper contact 4 and the lower contact 6 through butt joint. Except the controllable valve, the additional 2 lines can be connected with a water pump, a wall-mounted furnace, air energy, solar energy and the like. When the valve is opened, the equipment is synchronously started, otherwise, the equipment is closed. And can be directly connected to the equipment without additional accessories. It should be noted that the driving part 1 and the driven part 2 are mature technical means, 220V voltage is applied to the driving part 1, the driving part 1 generates heat in the normal working condition to eject the ejector rod, the ejector rod ejects the lower contact 6 on the top of the driven part 2 to move upwards, and the lower contact 6 is in butt joint with the upper contact 4 to connect a circuit.

The fixing plate is characterized by further comprising a shell 9 and a fixing plate 10 fixedly installed on the shell 9, wherein the fixing plate 10 is elastically connected with the upper connecting plate 3 through a spring 11. Elastic connection is favorable to using for a long time, utilizes elasticity can keep inseparable butt simultaneously, ensures that the action triggers sensitively and reliably.
