Vortex type floating ball check valve

Abstract

The invention discloses a vortex type floating ball check valve. The check valve includes a check valve body, the check valve body is provided with a connecting member, the connecting member is rotationally connected with a rotating member, the rotating member includes a horn-shaped rotating body, and the inner wall of the horn-shaped rotating body is provided with blades distributed in an array.According to the check valve, rainwater falls into the horn-shaped rotating body and impacts the blades, at the time, part of gravity potential energy and kinetic energy of the rainwater is convertedinto kinetic energy of the rotating member, so that the rotating member rotates on the connecting member, and the rainwater rotates together with the rotating member; under the action of gravity, therainwater passes through the connecting member to flow out through the check valve body, in the flowing-out process, the rainwater obtains power potential energy in the rotating member, and the rainwater has the rotating speed to flow out, so that the drainage efficiency is improved, and accumulation of excessive rainwater is avoided; and when the precipitation amount is equivalent to the drainagetime, the diameter of a drainage pipe required by the vortex type floating ball check valve is small, and the drainage cost is reduced.

Description

technical field [0001] The invention relates to a one-way valve, in particular to a scroll type floating ball one-way valve. Background technique [0002] The drainage system of the floating roof is very important to the oil storage. Without a drainage system, the rainwater will flow into the oil tank, which will affect the oil quality and the weight of the floating roof. In the prior art, only the drainage pipe is used for drainage, and one end of the drainage pipe is fixed on the On the top, the other end is fixed on the oil tank for drainage. A one-way valve is connected to the drain pipe to prevent rainwater from flowing backwards. The efficiency of drainage is low and the cost is high. Contents of the invention [0003] The object of the present invention is to provide a vortex float check valve. Rainwater falls into the trumpet-shaped rotating body and impacts the blades. At this time, part of the gravitational potential energy and kinetic energy of the rainwater are...
