Description

超超临界带旁路球形密封止回阀  Ultra-supercritical band bypass ball seal check valve
技术领域 Technical field
本实用新型涉及止回阀领域， 具体涉及一种超超临界带旁路球形密封止回阀。  The utility model relates to the field of check valves, in particular to an ultra-supercritical belt bypass ball seal check valve.
背景技术 Background technique

In order to reduce energy consumption and increase power generation efficiency, power generation equipment is developing toward large-scale, high-parameter, and high-performance. The spherical seal check valve has no transmission member in the structure, freely opens and closes, and the sealing ball moves up and down in the cylindrical leakage net, and rotates arbitrarily without a fixed wear point. During the working process, the spherical surface wears evenly, and the shape accuracy is always maintained. The performance will not decrease with time, and the service life of the seal is improved. In the high-pressure pipeline, when the medium is reversed, the back pressure of the pressure medium will cause the sealing ball to close extremely quickly, which will cause a strong water hammer to the valve and the pipeline, thereby causing damage to the device and affecting safe production.
