Problems solved by technology

However, most of the common single-vane swing cylinders on the market are only suitable for room temperature environments.
In a high temperature environment, especially in a high temperature environment exceeding 200 ° C for a long time, the common single vane swing cylinder will cause seal failure due to high temperature denaturation of the sealing material, and eventually cannot be used

Description

technical field [0001] The invention belongs to the field of pneumatic transmission, relates to the field of single-blade swing cylinders, in particular to a high-temperature-resistant single-blade swing cylinder. Background technique [0002] In automation equipment, the single vane swing cylinder is widely used in the field of pneumatic transmission due to its characteristics of large rotation angle, small size, light weight, and compact structure, especially suitable for installations where the location is limited. However, most of the single-blade swing cylinders that are common on the market are only suitable for room temperature environments. In a high temperature environment, especially if it is used for a long time in a high temperature environment exceeding 200°C, the common single vane swing cylinder will cause seal failure due to high temperature denaturation of the sealing material, and eventually cannot be used. Contents of the invention [0003] In order to ...
