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) Description of the Prior Art
[0004] Generally, the conventional vacuum eliminator of water
faucet, referring to FIG. 1 is composed of a seat hole 5
transversely on a valve base, whose internal end is interlinked
with a pipe when its outer end forms a mouth, a stopper 6 fixed on
the base hole and interlinked with the base hole, a sliding block
7, which can be installed in the base hole and its interior has
many guide chutes 71, moreover a set of leakage-proof pads 8
opposite the perforation. For the forgoing units, the vacuum can be
eliminated in the pipe.
[0005] 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.
SUMMARY OF THE INVENTION
[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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Referring to the FIG. 2 and FIG. 3, the present invention is
to put the screw locking end 31 on the both sides of the water
faucet 3 through the shutter S of the granite counter to connect
the locking unit 4 and position the water faucet 3 on the shutter
S. in which, the locking unit 4 is composed of a locking screw cap
41 for the screw locking end 31, and a packing piece 42 locked in
the locking screw cap 41 and a non-returning pad 43, and a water
supply pipe 45 whose end and packing piece 41 are fixed and
extruded outwards from the lockhole 44. It can prevent the water
from seeping by means of tightly jointing with the non-returning
pad 43 in the locking screw cap 41 after the locking screw cap is
screwed on the screw locking end 31 of the water faucet.
[0014] In addtion, referring to the FIG. 4, the water flow is
vertically guided by the water supply pipe to the locking screw cap
41 and lockhole 44, and then to the interior of water faucet 3
through the screw locking end 31 to keep the water flow in the
water faucet 3 for supply waiting in the water control circuit.
Thereby, based on the arrangement of the structure, because the
water faucet 3 is designed directly with a locking unit 4 on the
screw locking end 31 to make the water flow can access direcly
through the locking screw cap 41 and lockhole 44 of the locking
unit 4 and position the water faucet 3 on the shutter S. The
distance L between shutter S and wall W can be shortened properly
to save space and consumptive materials.
[0015] As shown in FIG. 2 and FIG. 3: the present invention
comprises: a non-returning pipe 1, a pressure controller 2 and a
pressure-resisting ring 3, in which
[0016] The non-returning pipe 1 is a three-way pipe including water
inlet 11, water outlet 12 and air inlet 13;
[0017] 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;
[0018] 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;
[0019] As shown in FIG. 4: it is an embodiment of water flow in
accordance with the present invention. When the non-returning pipe
1 is under the state of water supply, the pressure-resisting ring 3
exactly can be pushed by the water to make the leakage-proof pad P
on the ladder-shaped side 32 can be absorbed on the edge 22 of
central hole of the pressure controller by the vacuum. At this
time, the air at the outside of blowhole 21 of the pressure
controller 2 is resisted by the pressure-resisting ring 3 and fails
to access to, so that the water flow can enter into the water inlet
11 of the non-returning pipe smoothly and outflow the water outlet
12 (as shown in FIG. 4-A);
[0020] 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 FIG.
4-B);
[0021] 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.
