Anti-siphon device for ships

Abstract

The invention discloses an anti-siphon device for ships, and belongs to the technical field of ship accessories. The anti-siphon device comprises a first pipeline, a waste water pool, a second pipeline, a hose, a soft plate, a second corrugated pipe, a controller, a third pipeline, a fourth pipeline, a pressure sleeve, sliding rails, sliding blocks, connecting rods, connecting blocks, air cylinders, supporting rods, a first corrugated pipe, movable blocks, linear motors, brackets, support columns and a protective frame, wherein the first pipeline is mounted on the waste water pool; the first corrugated pipe is mounted at the lower end of the first pipeline; the second pipeline is mounted under the first corrugated pipe; the hose is mounted under the second pipeline; the soft plate is mounted under the hose; the second corrugated pipe is mounted under the soft plate; the third pipeline is mounted under the second corrugated pipe; the fourth pipeline is mounted under the third pipeline; and the protective frame is mounted on the first pipeline and the fourth pipeline. The anti-siphon device disclosed by the invention has the advantage that negative pressure in the pipelines can be eliminated.

Description

technical field [0001] The invention relates to a marine anti-siphon device, which belongs to the technical field of marine equipment. Background technique [0002] In recent years, there are often news media reports that the tap water of a certain ship is blue water, and the tap water has a smell. The reason is that various types of flushing valves were not installed as required during production and installation. Anti-siphon devices. At the same time, the structure of anti-siphon devices on the market is relatively complex, and the effect is not significant, resulting in high cost and poor effectiveness, which has led to shipbuilding companies not being willing to install and purchase. The anti-siphon device in the prior art adopts a non-return method. When the pipeline has negative pressure, it cannot remove the negative pressure in the pipeline, so the effect is poor. In order to solve the above difficulties, it is necessary to develop a marine anti-siphon device that c...
