Description

Technical Field

[0001] The invention relates to a water cap, in particular to a bidirectional variable flux water cap. Background Art

[0002] Ion exchange equipment filled with resin in water treatment systems needs to be equipped with a water distribution device to achieve uniform water distribution. The water cap is the main component of the water distribution device, which is used to ensure uniform distribution or collection of water flow and prevent fillers (such as resin, filter material, etc.) from being washed out of the equipment.

[0003] The flow rate of the ion exchanger in the water treatment system when producing water is called the operating flow rate. When the resin fails, it needs to be regenerated with acid or alkali. At this time, the liquid flows in the opposite direction to the produced water, and the flow rate is called the regeneration flow rate. The operating flow rate and the regeneration flow rate have large differences and are in opposite directions. However, if the flux of the water distribution device in the equipment remains unchanged, the flow rate cannot be controlled differently, which will result in insufficient regeneration or excessive use of acid and alkali, and increase the difficulty of handling the regeneration waste liquid. Summary of the invention

The present invention solves the problem that the running flow rate and the regeneration flow rate of the ion exchanger are greatly different and reverse in value by designing different structures inside the movable plug according to the needs of different flow rates, so as to adjust the bidirectional flux of the water cap, but when the flux of the water distribution device in the equipment remains unchanged, the flow rate cannot be controlled differently, and insufficient regeneration or excessive use of acid and alkali will occur, and the difficulty of treating the regeneration waste liquid will also increase.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0024] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Specific implementation method: Figures 1 to 5 As shown, the present invention provides a bidirectional variable flux water cap, the water cap 2 includes: a water cap head 3, a water cap rod 4, and a lower nut 5, the water cap head 3 is connected to the water cap rod 4, and the water cap rod 4 is connected to the lower nut 5.

[0026] A movable plug 6 is arranged inside the water cap head 3. The movable plug 6 is spherical. When liquid flows through the water cap 2 from bottom to top, the movable plug 6 is lifted up, and the liquid can pass through the water cap 2. When liquid flows through the water cap 2 from top to bottom, the movable plug 6 is pressed by the water flow at the waterway outlet of the water cap rod 4. The movable plug 6 can be designed with different structures inside the movable plug 6 according to the needs of different flow rates.

[0027] Preferably, when it is necessary to completely seal the water cap 2 when the liquid flows from top to bottom, a solid spherical movable plug 6 can be used, or a design scheme in which a bottom circular hole 7 is provided in the solid spherical movable plug 6 can be used, such as Figure 4 In the scheme shown, because the center of gravity of the sphere is distributed at one end of the sphere, the center of gravity of the movable plug 6 can completely block the waterway opening of the water cap rod 4 downward, and the movable plug 6 can completely block the waterway opening, and the liquid cannot flow through the water cap 2 from top to bottom. This scheme is used in the part where the waterway is fully open when the liquid flows through the water cap 2 from bottom to top, and the waterway is fully closed when the liquid flows through the water cap 2 from top to bottom.

[0028] Preferably, the movable plug 6 is provided with a bottom square hole 8, and when the liquid flows through the water cap 2 from top to bottom, the movable plug 6 is pressed by the water flow at the water outlet of the water cap rod 4, such as Figure 5 In the scheme shown, the movable plug 6 can partially block the waterway opening of the water cap rod 4, so that the liquid cannot flow through the water cap 2 from top to bottom, but the liquid can partially flow through the water cap rod 4 from top to bottom. This scheme is used in the parts where the waterway is fully open when the liquid flows through the water cap 2 from bottom to top, and the waterway needs to be unobstructed with a small flow when the liquid flows from top to bottom.

[0029] Preferably, the movable plug 6 is provided with a bottom square hole 8, and the end surface of the bottom square hole 8 is provided with a plurality of fine holes 9 penetrating the movable plug 6, such as Figure 6 In the solution shown, the movable plug 6 can partially block the waterway opening of the water cap rod 4, and the liquid can partially flow through the water cap rod 4 from top to bottom and can also flow through the fine hole 9.

[0030] This solution is used in places where the water channel is fully open when the liquid flows through the water cap 2 from bottom to top, and where a small flow of water needs to be unobstructed and a certain minimum flow needs to be guaranteed when the liquid flows through from top to bottom. The aperture and number of the pores 9 are designed according to the minimum flow requirement.

[0031] The present invention solves the problem that the operating flow rate and the regeneration flow rate of the ion exchanger have large numerical differences and are in opposite directions by designing different structures inside the movable plug according to the needs of different flow rates, thereby adjusting the bidirectional flux of the water cap. However, when the flux of the water distribution device in the equipment remains unchanged, the flow rate cannot be differentially controlled, which will result in insufficient regeneration or excessive use of acid and alkali, and will also increase the difficulty of treating the regeneration waste liquid.

[0032] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
