When the water level in the tank rises to a certain level, the outlet of the vacuum inhibitor can be blocked, so that the pressure in the tank is gradually formed, and the pressure in the tank is gradually increased along with the continuous entering of water in the pipe network until the pressure in the tank is balanced with the pressure of the water inlet pipe network, and the water level in the non-negative pressure tank can be stabilized.

A steady flow tank without negative pressure and cleaned by filtration is proposed in the patent of application number CN 202221431198.5; the patent with the application number of CN201920783460.4 proposes a steady flow tank with an end cover detached and sterilized and cleaned; the patent with the application number of CN201520848162.0 proposes a steady flow tank with firm structure and long service life. None of the above patents address the problem of swirl generation and its derivative during the water flow from inflow to outflow.

The water supply system stores water through the stainless steel steady flow tank, the water inlet and the vacuum eliminator are respectively arranged at two sides of the top of the steady flow tank, and the water outlet is arranged in the middle of the bottom of the steady flow tank. The arrangement mode can enable water flow to flow from the water inlet of the stainless steel steady flow tank and then flow out from the water outlet after one turn. The vortex can be induced to generate a plurality of eddies in the flowing process of the inflow water, the energy of the inflow water can be consumed by the eddies, the sedimentation effect of suspended impurities in the water is affected, the impurities deposited at the bottom of the tank can be rolled up, and the water quality is lowered along with the outflow of the water flow.

Detailed Description

The utility model provides a pipe network laminated water supply vortex-inhibiting steady flow tank, as shown in figure 2, which comprises a fluid inlet 1, a vacuum eliminator 2, a sewage outlet 3, a fluid outlet 4 and a vortex-inhibiting plate 5.

The vortex suppressing plates 5 are vertically installed at intervals on both sides of the fluid inlet 1, the fluid outlet 4, the drain 3 and the vacuum eliminator 2 to suppress the generation of vortices. The fluid inlet 1 and the vacuum eliminator 2 are positioned at the top of the steady flow tank, the fluid outlet 4 and the sewage outlet 3 are positioned at the bottom of the steady flow tank, and the fluid outlet 4 is positioned in the middle of the bottom of the steady flow tank.

In order to ensure the inhibition effect and not to influence the normal flow of the water in the steady flow tank, the number N of the vortex inhibition plates is 4-6, the number N=5 is shown in the figure, and the vortex inhibition plates are arranged at the position shown in fig. 2.

The cross section diameter of the steady flow tank is D, the height of the vortex suppression plate 5 is H, in order to achieve good vortex suppression effect and not to influence the normal flow of water in the steady flow tank, the height of the vortex suppression plate 5 is recommended to be H=0.3D-0.7D, and the height of the vortex suppression plate 5 shown in fig. 2 is 0.5D.

In order not to influence the normal flow of water in the steady flow tank, a certain gap 2-1 is reserved between a vortex suppression plate 5 arranged at the bottom of the steady flow tank and the wall surface of the tank bottom, and the gap delta=0.1D-0.2D, so that the water can flow through the gap. The section of the steady flow tank after the height installation of the gap is shown in fig. 3, and the left and right diagrams are respectively the section views of the vortex suppression plates installed at the top and bottom of the steady flow tank. As shown in fig. 4, in order to reduce the weight of the steady flow tank and ensure the circulation capacity, a certain number of circular holes 4-1 with proper size can be added on the vortex suppression plate 5 to allow the liquid to pass through.

The specific working principle of the utility model is as follows: when water flows into the steady flow tank from the fluid inlet 1, the vortex suppression plate 5 prevents water flow from driving surrounding water bodies to flow so as to generate large-scale vortex, wherein the main flow area is from the fluid inlet 1 at the left side of the top of the steady flow tank to the fluid outlet 4 at the center of the bottom, and the water bodies in other areas of the steady flow tank do not generate intense vortex flow. When water at the bottom of the tank flows, the water can pass through the gap between the vortex suppression plate 5 and the lower wall surface of the steady flow tank, and can not accumulate in a space to stop flowing. When the liquid level in the steady flow tank rises to the top, the gap on the vacuum eliminator 2 is blocked, and when the liquid level drops, the gap on the vacuum eliminator 2 is opened to allow air to flow in to prevent vacuum.
