Adjustable single-door same-direction shutoff valve

Abstract

The invention discloses an adjustable single-door co-directional shut-off valve, which comprises a buoy, a telescopic rod, a single-door water retaining plate, a gate, a box body, a rotating shaft, and a sealing rubber ring. The gate is fixed on the box. On one side of the body, there is a water outlet hole in the middle of the gate, and there is a sealing rubber ring around the water outlet hole. One side has a limit post, and the rotating shaft is located above the water outlet. One end of the single-door water baffle is connected. This device uses buoyancy to drive the buoy to move up, thereby driving the single-door water baffle to close the door, realizing initial rainwater interception, and can be used for municipal and water conservancy systems such as initial rainwater collection, rainwater pipeline anti-backflow, etc. , without external power and manual maintenance, it is worth promoting.

Description

technical field [0001] The invention relates to the field of drainage devices, in particular to a valve which uses a floating ball to drive a water baffle to realize flow interception. Background technique [0002] Drainage system refers to the overall combination of drainage collection, transportation, water quality treatment and discharge and other facilities in a certain way. The general term for all levels of drainage ditches (pipes) and buildings used for waterlogging, waterlogging, and salt prevention. It is mainly composed of field drainage regulation network, drainage ditches at all levels, waterlogging lakes, drainage sluices, pumping and drainage pumping stations, and drainage capacity and discharge areas. In rainy days, the rainwater pipe network needs to intercept the initial rainwater with a lot of dirt , It is necessary to use a shut-off valve, but the previous shut-off valve has the disadvantages of needing maintenance and external power.
