It has good sealing performance, high integration, small size and light weight, and effectively avoids the original brake device. The numerous external pipelines are easy to cause oil and gas leakage. It can not only realize automatic braking, but also has a manual braking function, and the manual braking and automatic braking functions do not affect or interfere with each other. It has high reliability and strong stability. According to the technical solution disclosed by it, when the existing hydropower station brake valve equipment is used, on the one hand, when the valve is adjusted manually, it is easy to have a large rotation torque, which makes the work more laborious, or a long rotation stroke, which reduces the work efficiency.
