Embodiment Construction

[0009] In the figure, when the helical wire (1) is heated or cooled, it is confined within the confinement frame (2). Since the telescopic ends (3) and (4) of the helical wire are free movable ends, a large displacement can be achieved, and the purpose of driving some mechanical parts can be achieved by using this displacement.

[0010] One of the telescopic ends (3) and (4) of the above-mentioned helical wires can be fixed to achieve or obtain a larger displacement.

Abstract

The invention discloses a spiral wire stretching and retracting temperature-driving method and application thereof. The spiral wire stretching and retracting temperature-driving method is characterized in that a spiral wire is fixed in a limiting frame, when the temperature of the spiral wire changes, the spiral wire expands or contracts, and finally the end of the spiral wire is moved; and the movement of the end of the spiral wire is used for driving a mechanical part to act, so that the actions such as opening and closing of a valve are achieved.

Description

technical field [0001] A thermodynamic drive method. Background technique [0002] In life and production, it is often necessary to use temperature changes to drive certain mechanical components, such as valves in gas pipelines. Currently, there are some temperature-driven components, such as bimetallic strips. But the range of motion is small, making it difficult to actuate larger mechanical parts such as valves. Contents of the invention [0003] For this reason, the present invention provides a spiral wire stretching temperature driving method and its application, which is characterized in that: the spiral wire is fixed in a limiting frame, when the temperature changes, the spiral wire expands or contracts, and finally manifests as a spiral The displacement of the end of the wire; use this displacement to drive the action of mechanical parts to complete actions such as switching valves. [0004] The above-mentioned helical wire telescopic temperature driving method c...
