Vacuum eliminator

Abstract

The prevent invention comprises a non-returning pipe, pressure controller and pressure-resisting ring respectively, whose larger ring-shaped side exactly resists the water inlet edge of the non-returning pipe, in which some interlinked vents are designed on the larger ring-shaped side while a leakage-proof pad on the ladder-shaped side for the pressure-resisting ring. In that way, the pressure-resisting ring is pushed towards the pressure control and the leakage-proof pad exactly would be absorbed by the vacuum at the edge of central hole in the case of water's access to the non-returning pipe. And the pressure-resisting ring can eliminate the vacuum absorption with its gravity and air suction to form an unobstructed water flow and block backward the water inlet edge of the non-returning pipe to prevent the water flow's reflux from access to the interior of the non-returning pipe for longer service life of water transport pipeline and balance the returning water operation safety. Thereby, it not only would not easily be involved in denaturation and failure, but also has simple structure and exact operation besides its easy assembly.

Description

BACKGROUND OF THE INVENTION [0001] 1) Field of the Invention [0002] A kind of normal-opened-model vacuum eliminator, in which some interlinked vents are designed on the larger ring-shaped side of the pressure controller, and a leakage-proof pad is designed on the ladder-shaped side for the pressure-resisting ring. In that way, the pressure-resisting ring is pushed towards the pressure controller and the leakage-proof pad exactly would be absorbed by vacuum at the edge of central hole of the pressure controller in the case of water's access to the non-returning pipe. And the pressure-resisting ring can eliminate the vacuum absorption with its gravity and air suction and block backward the water inlet edge of the non-returning pipe to prevent the water flow's reflux from access to the interior of the non-returning pipe. Thereby, it not only would not easily be involved in denaturation and failure, but also has simple structure and exact operation besides its easy assembly. [0003] 2) D...

Benefits of technology

[0006] The normal-opened-model vacuum eliminator the prevent invention provides, whose larger ring-shaped side exactly reaches the water inlet edge of the non-returning pipe, in which some interlinked vents are designed on the larger ring-shaped side of the pressure controller, and a leakage-proof pad is designed for on the ladder-shaped side for the pressure-resisting ring. In that way, the pressure-resisting ring is pushed towards the pressure controller and the leakage-proof pad exactly would be absorbed by the vacuum at the edge of central hole of the pressure controller in the case of water's access to the non-returning pipe. And the pressure-resisting ring can eliminate the vacuum absorption with its gravity and air suction to form an unobstructed water flow and block backward the water inlet edge of the non-returning pipe to prevent the water flow's reflux from access to the interior of the non-returning pipe to expand the service life of water transport pipeline and balance the returning water operation safety. Thereby, it not only would not easily be involved in denaturation and failure, but also has simple structure and exact operation besides its easy assembly.

Problems solved by technology

Nevertheless, we find out that the forgoing prior art is not so fine as we expected.

Because all its parts are made of plastic materials, they not only would be easily involved in denaturation and failure, but also the outside force is required to block backward the water inlet edge for its small weight while operating themselves.

More seriously, its action would be incorrect.
