Abstract

The invention provides a wall-mounted type sleeve drain valve. The wall-mounted type sleeve drain valve comprises a valve body, an indicator rod, a flow guide device, a sleeve brake, a sleeve, a mainseal ring, an access cover, a sliding seal ring, a displacement sensing device, a hydraulic cylinder and a tumbler. The hydraulic cylinder drives the sleeve brake to move, and the indicator rod move front and back with the sleeve brake and drives the tumbler to swing. The tumbler drives an output shaft of the displacement sensing device to rotate, and the linear displacement converting into a rotation signal is realized. Compared with prior art, the wall-mounted type sleeve drain valve realizes free drain in air or under water, has no erosion to vegetation, mountains and river beds at an outlet, and saves land and construction cost.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower industry, in particular to a wall-mounted sleeve discharge valve. Background technique [0002] Generally, pipelines, especially under high pressure conditions, directly discharge to the atmosphere or underwater. Due to the high flow velocity and high pressure at the pipeline outlet, there will be greater erosion on the vegetation, mountains and riverbeds at the pipeline outlet. [0003] Common practice requires the construction of flow-directing structures on embankments. The structure occupies a large area, is high in cost, and has a long construction period. [0004] Therefore, it is necessary to provide a wall-mounted sleeve discharge valve to solve the above technical problems. Contents of the invention [0005] The purpose of the present invention is to provide a wall-mounted sleeve discharge valve, which is installed at the end of the pipeline and the discharge ...
