Embodiment 1

[0045] figure 1 is a schematic diagram of the liquid expansion protector of the present invention;

[0046] figure 2 is the internal schematic diagram of the liquid expansion protector of the present invention;

[0047] like figure 1 and figure 2 As shown, this embodiment provides a liquid expansion protector, which includes: a temperature sensing component 1, a push rod 2, and at least one trigger component 3 linked with the push rod 2; the temperature sensing component 1 is suitable for When the obtained temperature reaches the preset value, the push rod 2 is pushed up to trigger the trigger component 3 . When the temperature obtained by the temperature sensing component 1 reaches the preset value, the push rod 2 moves upward to trigger the trigger component 3, so that the external circuit is disconnected, so as to cut off the power supply, prevent the temperature from being too high, and improve the safety performance of the liquid expansion protector .

[0048] In ...

Embodiment 2

[0060] On the basis of embodiment 1, this embodiment 2 provides a working method of a liquid expansion protector, including: when the temperature obtained by the temperature sensing component 1 reaches a preset value, the push rod 2 drives the spring through the guide block 21 The sheet 31 rises to separate the reed 31 from the static contact sheet 32, that is, the external circuit is disconnected.

[0061] For the specific structure and working principle of the liquid expansion protector mentioned in the second embodiment, please refer to the description in the first embodiment, and will not be repeated here.

[0062] In summary, in the liquid expansion protector and its working method of the present invention, when the temperature obtained by the temperature sensing probe 11 is too high, the internal pressure of the temperature sensing component 1 will increase to a critical value, and the diaphragm 131 will bulge, pushing The push rod 2 rises, so that the movable contact 31...

Abstract

The invention belongs to the technical field of temperature controllers, and particularly relates to a liquid expansion type protector and a working method thereof. The liquid expansion type protectorcomprises a temperature sensing assembly, a push rod and at least one triggering assembly in linkage with the push rod. The temperature sensing assembly is suitable for pushing the push rod to rise when the obtained temperature reaches a preset value so as to trigger the triggering assembly. According to the liquid expansion type protector and the working method thereof, when the temperature obtained by the temperature sensing assembly reaches the preset value, the push rod moves upwards to trigger the triggering assembly, disconnection of the contact is rapidly achieved, and the safety performance of the liquid expansion type protector is improved.

Description

technical field [0001] The invention belongs to the technical field of temperature controllers, and in particular relates to a liquid expansion protector and a working method thereof. Background technique [0002] The liquid expansion temperature controller is also called the fluid medium temperature controller, which realizes the automatic adjustment of the temperature by utilizing the principle of thermal expansion and contraction of the temperature-sensitive fluid and the incompressibility of the liquid. [0003] However, the existing liquid expansion temperature controller has the following defects: when the temperature obtained by the temperature sensing component is too high, the disconnection of the contacts cannot be quickly realized, which may easily cause safety accidents. Contents of the invention [0004] The purpose of the present invention is to provide a liquid expansion protector and its working method. When the temperature acquired by the temperature sensi...
