Abstract
The invention discloses a hydraulic control type test method for a hydraulic balance valve. The hydraulic control type test method comprises the following steps of: at first, adjusting and locking a security pressure value of a safety valve; secondly, obtaining positive flow resistance and inverse flow resistance of a single path of the hydraulic balance valve through a single-path flow resistance test (a positive channel and an inverse channel); and finally, calculating flow resistance of the entire balance valve by means of shortly connecting an oil opening. With the adoption of the method provided by the invention, basic parameters (such as security valve pressure, single-path positive flow resistance, inverse flow resistance, and flow resistance of the entire valve) of the hydraulic control type test method for the hydraulic balance valve can be obtained, so as to provide certain important foundations for examination and acceptance inspection of the balance valve.
