Embodiment Construction

[0031] The core of the present invention is to provide a waterproof electric heating actuator, the structural design of the waterproof electric heating actuator can make the actuator have waterproof performance, so it can work in a humid environment for a long time, avoiding circuit short circuit or flashover phenomenon occur.

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Please refer to figure 1 , figure 1 It is a schematic diagram of the structure of a waterproof electric heating actuator in an embodiment of the present invention.

[0034] In one embodiment, such as figure 1 As shown, the electrothermal actuator provided by the present invention includes a handle housing 1 in which a driving part is provided, and the driving part drives the transmission push rod...

Abstract

The invention discloses a water-proof electric heating actuator. A drive element of the water-proof electric heating actuator comprises a temperature sensing bulb fixing sleeve (3) which is installed inside a handle shell (1), a temperature sensing bulb (4) which is arranged inside the temperature sensing bulb fixing sleeve (3), and a reset part (5), wherein a rod part (41) which extends out or draws back inside the temperature sensing bulb (4) along with the change of temperatures is arranged inside the temperature sensing bulb (4) so that when extending out, the rod part (41) can push a transmission push rod (2) to move downwards, when the rod part(41) draws back, the reset part (5) drives the transmission push rod (2) to reset; a through hole which enables a lead line (6) to penetrate out is formed in the side wall of the temperature sensing bulb fixing sleeve (3), and the lead line (6) further penetrates through the through hole through a sealing pad (71) to seal. The structural design of the water-proof electric heating actuator can enable the actuator to have the water-proof performance, and therefore the water-proof electric heating actuator can work in a humid environment for a long time and the phenomenon of circuit cutting-out or arcing is prevented from occurring.

Description

Technical field [0001] The invention relates to the technical field of thermostatic valves, in particular to a waterproof electric heating actuator. Background technique [0002] Electric heating actuator, also known as electric heating thermostat, is a new concept device for remote control of system flow and heat (cold capacity). It is suitable for heating and central air conditioning temperature control in residences, shopping malls, and hotels. Temperature control in separate rooms. [0003] Electric heating actuators are mainly used in floor heating systems to control the closing and opening of pipes. It is specifically applied to the electric drive part of the electric actuator of branch valve, small valve and dynamic balance valve. There is no noise in working and running, and the nut connection installation method is simple, quick to install and easy to disassemble. [0004] The prior art electric actuators generally do not have the waterproof function. When the air is rela...
