[0033] Example 1:
[0034] See Figure 1-5 , The present invention provides a technical solution: a control valve arc extinguishing device for a thermal power plant, comprising: a housing 1, a static end conductive block 2, a blowing mechanism 4, a static end conductive rod 6, a movable conductive rod 7 and a connecting seat 9.
[0035] Wherein, the housing 1 is specifically made of ceramic material.
[0036] Further, the overall shape of the housing 1 is a cylindrical structure.
[0037] Wherein, the blowing mechanism 4 includes a sleeve 3 and a cylinder 15. A cylinder 15 and a thread hole 10 are opened around the inside of the sleeve 3, and the thread hole 10 is fixedly connected to the bottom end of the cylinder 15. A second spring 21 is fixedly installed at the inner bottom end of the second spring 21, a piston 20 is fixedly installed at the upper end of the second spring 21, and the piston 20 and the cylinder 15 are slidingly connected, and the inner wall surface of the sleeve ...
