Embodiment Construction

[0024] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0025] Such as Figure 1 to Figure 6 As shown, this electrothermal actuator is mainly used in floor heating heating systems to control the closing and opening of valves in pipelines. It includes a base 1, a temperature bulb 9, an electric heating element 10, a fixing seat 2 and an elastic connection mechanism.

[0026] Such as Figure 2 to Figure 4 As shown, specifically, the fixed seat 2 is cylindrical, and the outer part of the fixed seat 2 has three guide holes 23 that are evenly distributed in the circumferential direction and axially penetrated. Each guide hole 23 is perforated with a 23 structure corresponding to the guide column 5, one end of the guide column 5 is fixedly connected with the base 1, and the guide c...

Abstract

The invention provides an electric heating actuator, which belongs to the technical field of mechanical engineering. The electric heating actuator solves the problems of complex structure and convenient use of the conventional electric heating actuator. The electric heating actuator comprises a fixed seat and a base which can be fixedly connected with a valve body, wherein a thermometer bulb and an electric heating element are fixed in the fixed seat; the electric heating element is connected with the body of the thermometer bulb; and the fixed seat is connected with the base through an elastic connecting mechanism which ensures that one end of the fixed seat always has a trend of moving towards a direction leaning against the base. The electric heating actuator has the advantages of reasonable and compact structure design, attractive appearance, stable performance and long service life, and is convenient and safe to use.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and relates to a flow regulating device, in particular to an electrothermal actuator. Background technique [0002] Electrothermal actuator is a device used to remotely control system flow, heat (cooling capacity). Electrothermal actuators are mainly used in floor heating systems to control the closing and opening of pipeline valves; they are specifically used in manifold branch valves, small valves, and dynamic balance valves. Related documents about electrothermal actuators, such as an electrothermal actuator disclosed in Chinese patent literature [Patent No.: ZL200920187875.1, authorized announcement number: CN201513624U]. Although the electrothermal actuator has manual and automatic opening and closing functions, it also has the problems of complex structure and inconvenient use. Contents of the invention [0003] The object of the present invention is to solve the above-me...
