An automatic constant valve for water level of anti-seepage channel

Abstract

The invention relates to a seepage-preventing ditch water level automatic constant valve. The seepage-preventing ditch water level automatic constant valve has the innovation point that the seepage-preventing ditch water level automatic constant valve comprises a floating barrel, a fixed valve plate, a valve flap, a connection plate, extensible corrugated hoses, a three-way opening, a bottom plate and a protective cover. The seepage-preventing ditch water level automatic constant valve has the advantages that through the height difference of the medium water level and the upstream water level of a seepage-preventing ditch and buoyancy of the floating barrel, opening and closing control over the seepage-preventing ditch water level automatic valve is achieved, thus the effect that the water level height in the seepage-preventing ditch is always kept at the set water level height is ensured, and accordingly the conditions that when the demanded irrigation quantity of a lower level ditch is reduced and water inflow of a flashboard is not controlled in time by an upper level ditch, consequently the water level of the lower level ditch rises suddenly, water is made to overflow the dike top of the ditch, and when overflowing is serious, the ditch is damaged and dry land crops are drown are avoided, and the overflowing phenomenon of the lower level ditch is prevented effectively.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to an automatic water level constant valve for an anti-seepage canal. Background technique [0002] Farmland water-saving irrigation has risen to the height of my country's basic national policy. In recent years, the country's investment in farmland water-saving irrigation infrastructure has a huge amount of economic aggregate, and it is increasing year by year. As far as the anti-seepage canal is concerned, it is as high as tens of billions every year. The purpose of building anti-seepage canals is to prevent part of the water from leaking from the soil when passing through the canals, resulting in waste of water and electricity. However, after the construction of the anti-seepage canals, it did not completely solve the problem of water waste and channel safety. This is because the canals in our country The water control method is primitive and backward. It is still an...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an automatic constant water level valve for anti-seepage canals. The water control valve provided can solve the problem that the water level cannot be automatically constant when the canal is filled with water.
