1) Field of the Invention
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.
2) Description of the Prior Art
Generally, the conventional vacuum eliminator of water faucet, referring to
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.
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.
Referring to the
In addtion, referring to the
As shown in
The non-returning pipe 1 is a three-way pipe including water inlet 11, water outlet 12 and air inlet 13;
The pressure controller 2 is T-shaped, and its larger ring-shaped side 21 exactly resists the water inlet edge 13 of the non-returning pipe 1, in which some interlinked vents 211 are designed on the larger ring-shaped side of the pressure controller. When the air enters into from the interlinked vents 211, the vacuum absorption state of the pressure controller 3 and the pressure-resisting ring 3 can be eliminated to make the pressure-resisting ring 3 block backward the water inlet edge 11 of the non-returning pipe 1 for avoiding the water flow's reflux; and a perforation 23 is designed on the larger ring-shaped side 21 for the pressure controller 2, which is fixed with a cover 4 by a bolt T to form a closed state;
The front end 3 of the pressure-resisting ring extrudes a little into the guide head 31 in the central hole of the pressure controller, and a leakage-proof pad P is designed on the ladder-shaped side 32 for the pressure-resisting ring 3. In that way, the pressure-resisting ring is pushed towards the pressure controller 2 and the leakage-proof pad P exactly would be absorbed by the vacuum at the edge 22 of central hole of the pressure controller 2 in the case of water's access to the non-returning pipe to form an unobstructed water flow;
As shown in
And because the pressure-resisting ring 3 hasn't the water flow pressure to resist under the water stopping state, the air at the outside of pressure controller 2 can enter into the non-returning pipe 1 through the blowhole 21 to eliminate the vacuum absorption of the pressure controller 2 and pressure-resisting ring 3 and form an inlet valve room R. And the pressure-resisting ring 3 blocks backward the water inlet edge 11 of the non-returning pipe 1 with its gravity and air suction to make the water flow from the water inlet 11 and would not return to the non-returning pipe with some foreign substance for good water resources and longer service life of the water transport pipeline, balancing the returning water operation safety (as shown in
Because the pressure controller 2 and the pressure-resisting ring 3 are made of metal materials, the pressure-resisting ring 3 can eliminate the vacuum absorption with its gravity. And it not only would not easily be involved in denaturation and failure, but also has simple structure and exact operation besides its easy assembly.
