Simple detachable heat insulation device applied to hydraulic valve

The utility model discloses a simple detachable heat insulation device applied to a hydraulic valve. Due to the fact that the valve is compact in structural design, a hydraulic actuator is prone to being affected by heat radiation, an end sealing piece is aged and damaged to leak oil, and seriously, hydraulic oil leaks into a high-temperature heat body to cause fire behaviors and even fire disasters. The device comprises two semicircular plates (5), the two semicircular plates are oppositely buckled to form a disc structure, the two semicircular plates are connected and fixed through a positioning plate (7), a semicircular groove (8) is formed in the center of each semicircular plate, and a clamping device (4) is fixed to each semicircular plate. The thermal insulation device is used for thermal insulation of the actuator. 应用于液动阀门的简易可拆卸隔热装置。因阀门结构设计紧凑，致使液动执行器易受到热辐射的影响，造成端部密封件老化损坏而漏油，严重的会导致液压油漏到高温热体而引起火情甚至火灾。本实用新型组成包括：两个半圆板（5），两个所述的半圆板对扣组成圆盘结构，两个所述的半圆板通过定位板（7）连接固定，每个所述的半圆板的中心都开设有半圆槽（8），每个所述的半圆板上都固定有夹紧器（4）。本实用新型
