Abstract

The invention discloses an air intake and exhaust pressure-bearing bidirectional pressure-regulating type water hammer protective device, and relates to a pipeline water hammer protective device. According to the invention, the problems of high installation height and water pollution existing for a directional pressure regulating tower are solved. According to the invention, the lower end of a pressue bearing water tank is provided with a supporting body; the top plate of the pressure bearing water tank is provided with an air valve opening and an overhauling port; the air valve opening is provided with an air valve; the overhauling port is provided with an overhauling closed cover; the bottom plate of the pressure bearing water tank is provided with a water injection opening and an air releasing opening; the water injecton opening is provided with a water injection pipe; the water injection pipe is provided with an overhauling valve; the air releasing opening is provided with an air releasing pipe; the air releasing pipe is provided with an air releasing vavle; the inner wall of the pressure water tank is provided with an air bag supporting plate; the air bag supporting plate is provided with an air bag; one side of the air bag is connected with the air bag supporting plate through an elastic pulling rope, and the other side of the air bag is connected with the inner wall of the pressure bearing water tank through the elastic pulling rope; and an energy dissipation plate is installed fixedly on the inner wall of the pressure bearing water tank. The air intake and exhaust pressure-bearing bidirectional pressure-regulating type water hammer protective device provided by the invention is especially suitable for a water pipe with obvious changes of topographic inequality.

Description

technical field [0001] The invention relates to a pipeline water hammer protection device, in particular to an inlet and exhaust pressure-bearing two-way pressure-regulating water hammer protection device, which belongs to the technical field of long-distance water pipeline protection equipment. Background technique [0002] In my country, due to the unbalanced spatial distribution of water resources and differences in regional water consumption, some cities or regions have to transfer water from other places. Many long-distance water transmission projects have been put into use, and more long-distance water transmission projects are being or It is about to be constructed, and the water delivery method using pipelines is more and more widely used due to its advantages of less terrain restrictions, less water loss, and less water pollution. The accompanying water hammer also caused damage to pipelines and submerged pump stations , Casualties and other issues, so the water hamme...
