Referring to fig. 1, 2 and 3, fig. 1 is a schematic structural view of a non-negative pressure tank apparatus 1 provided by the present invention, fig. 2 is a schematic structural view of a vacuum suppressor water flood prevention device 10 provided by the present invention, and fig. 3 is an enlarged schematic view of a point C in fig. 2.

To achieve at least one of the advantages or other advantages, an embodiment of the present invention provides a non-negative-pressure tank apparatus 1. As shown, the no-negative pressure tank apparatus 1 includes a flow stabilization tank 2 and a vacuum suppressor 5. The vacuum suppressor 5 is arranged at the opening 4 of the steady flow tank 2 and is used for suppressing negative pressure generated in the steady flow tank 2, solving the problem of negative pressure of water supply equipment, keeping pressure balance and realizing normal water supply.

As shown in fig. 2, the vacuum suppressor overflow preventing device 10 is directly fixed above the vacuum suppressor 5 by means of flange connection, and is suitable for upgrading and reconstructing the existing flow stabilization tank 2. The vacuum suppressor water flood prevention device 10 may include a tubular housing 12, a sump 14, a drip cover 16 and a drainage plate 18. Further, the bottom of the sump 14 is provided with a drain 142, and the sump 14 communicates with the interior of the housing 12 via the drain 142.

A sump 14 is provided around the outer peripheral wall of the housing 12 for collecting water liquid overflowing from the vacuum suppressor 5. Preferably, the sump 14 is mounted at the belly of the housing 12. Preferably, the number of the drainage channels 142 at the bottom of the sump 14 is two, and the drainage channels are symmetrically distributed, which is beneficial to drainage. The housing 12, the sump 14 and the drainage channel 142 may be integrally formed, thereby simplifying the structure.

A drip cover 16 is located directly above the housing 12 for dust protection and to limit the height of water spills. When the vacuum suppressor 5 overflows, the overflowing water overflows from the top of the vacuum suppressor 5, and the liquid collecting cover 16 blocks the overflowing water and enables the water to flow to the surrounding drainage plates 18. Preferably, as shown in FIG. 2, the drip cover 16 is arcuate in shape to facilitate directing the water around.

A flow guide plate 18 is secured to the sump cover 16 for directing water into the sump 14. Preferably, the drainage plate 18 is integrally formed at the bottom of the cover 16 to collect overflow water into the sump 14. Preferably, the angle of inclination b of the flow guide plate 18 is in the range of 20-75 to facilitate the water to be guided into the sump 14.

In general, when water having a certain flow rate overflows from the top of the vacuum suppressor 5, the water first hits the liquid collecting cover 16, then flows around the liquid collecting cover 16, and then is guided by the flow guide plate 18 to change the flow direction, and finally flows to the liquid collecting tank 14.

In one embodiment, as shown in fig. 2, the vacuum inhibitor water flood prevention apparatus 10 may further include a shielding plate 20. A shielding plate 20 extends downward from the outer edge of the sump cover 16 to below the top of the sump 16 for preventing foreign objects from contaminating the water inside the vacuum suppressor water flood prevention apparatus 10. Preferably, the aperture D1 of the sump cover 16 is larger than the aperture D2 of the sump 14, so that the water inlet of the sump 14 is located inside the shielding plate 20, further preventing contamination by foreign objects. Preferably, the bottom of the protection plate 20 is lower than the top of the sump 14, i.e. there is a height difference H1 between the protection plate 20 and the sump 14, and the height difference H1 can ensure the circulation of air and prevent external foreign matters from polluting the water inside.

In one embodiment, as shown in fig. 2, the vacuum suppressor water flood prevention apparatus 10 further comprises a fixing bolt 22. The fixing bolt 22 penetrates the liquid collection cover 16 and abuts against the case 12 to connect the liquid collection cover 16 and the case 12. In other words, the drip cover 16 and the housing 12 are connected together by the fixing bolts 22 so that the drip cover 16 is detachable. Also, the installation height of the sump cover 16 may be adjusted by the screw-threaded degree of the fixing bolt 22.

In an embodiment, as shown in fig. 2 and 3, the vacuum suppressor water flood prevention apparatus 10 may further include a piston 24, a spring 26, and a piston cover 28. The piston 24 is disposed at the water inlet of the drainage channel 142. The spring 26 presses against the lower surface of the piston 24 and pushes the piston 24 upward to close the flow guide 142. The drainage channel 142 has a mounting hole 144 at a position opposite to the piston 24, the piston cap 28 is mounted in the mounting hole 144, and the piston 24 is connected to the piston cap 28 through the spring 26. Preferably, when the piston 24 does not completely block the water inlet 146 of the drainage channel 142, the liquid collecting tank 14 can be communicated with the housing 12 through the drainage channel 142, so that the overflowed water can flow back to the flow stabilizing tank 2 through the housing 12, thereby forming a water circulation and saving water resources.

Further, when water overflows from the flow stabilization tank 2 and overflows from the vacuum suppressor 5, the piston 24 blocks the water inlet 146 of the drainage channel 142 because the direction of the spring 26 is the same as the direction of the pressure difference, so that the water cannot overflow from the water inlet 146; when the water level in the flow stabilization tank 2 drops, the force generated by the pressure difference is larger than the force of the spring 26, the piston 24 moves downwards, the water inlet 146 is opened, and overflowed water flows back into the flow stabilization tank 2 through the drainage channel 142.

Preferably, spring 26 is perpendicular to the lower surface of piston 24 to facilitate the operation of the various components. Preferably, the water inlet 146 of the drainage channel 142 or the piston 24 may be designed to have a cone-shaped structure, and the cone-shaped structure may limit the highest position of the displacement on the piston 24, so as to prevent the piston 24 from being separated from the water inlet 146, without additional fixing members, and simplify the installation. The piston 24 is inserted through the mounting hole 144 of the drainage channel 142, the spring 26 is abutted against the lower part of the piston 24, and finally the piston cover 28 is screwed into the mounting hole 144 of the drainage channel 142 in a threaded manner, so that the mounting of the piston 24 is completed. The installation scheme is convenient and is beneficial to the subsequent cleaning and maintenance of the liquid collecting tank 14; furthermore, the piston 24 is limited by the liquid collecting groove 14, no additional parts or processing cost is needed, and the manufacturing cost is superior to that of a one-way valve. In addition, the piston 24 can limit the spraying direction of the overflowed water, so as to prevent the water from splashing out of the liquid collecting tank 14 through the drainage channel 142, and further prevent the water from overflowing.

It should be noted that the piston 24 and the liquid collecting cover 16 are both detachable, which is beneficial for installation and subsequent cleaning and maintenance.

In summary, an advantage of the present invention is to provide an overflow preventing device 10 for a vacuum suppressor and a non-negative pressure tank apparatus 1, which can recover water overflowing from the vacuum suppressor 5 by the arrangement of the liquid collecting tank 14, the liquid collecting cover 16 and the drainage plate 18, solve the overflow problem of the vacuum suppressor 5, reduce the corrosion risk of the apparatus due to overflow, and have simple structure, easy production and manufacture and low manufacturing cost.

Another advantage of the present invention is to provide an overflow preventing device 10 of a vacuum suppressor 5 and a non-negative pressure tank apparatus 1, which can protect water inside the structure from being polluted by dust and other foreign matters through the arrangement of a protection plate 20; through the height difference H1 setting of guard plate 20 and collecting tank 14, can effectively prevent that foreign matter such as outside dust from polluting inside water liquid when guaranteeing the gas circulation.

Another advantage of the present invention is to provide an overflow preventing device 10 for a vacuum suppressor and a non-negative pressure tank apparatus 1, which can guide the overflowed water to the flow stabilizing tank 2 again by the arrangement of the piston 24 and the spring 26, so as to save water resources. In addition, the piston 24 is limited by skillfully utilizing the water inlet of the drainage channel, and the effects of avoiding water overflow and enabling water liquid to flow back for the second time can be achieved without additionally arranging additional parts (such as a one-way valve).

Another advantage of the present invention is to provide a vacuum suppressor without overflow 510 and a negative pressure tank apparatus 1, which facilitate installation and subsequent cleaning, maintenance, etc. operations by detachably disposing both the piston 24 and the liquid collecting cover 16.
