Description

Technical Field

[0001] This utility model relates to a water cap, and more particularly to a constant pressure bidirectional controllable flow water cap. Background Technology

[0002] In water treatment systems, ion exchange equipment filled with resin 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, used to ensure the uniform distribution or collection of water flow, while preventing the packing material (such as resin, filter media, etc.) from being washed out of the equipment.

[0003] In a water treatment system, the flow rate of water produced by an ion exchanger is called the operating flow rate. When the resin becomes ineffective, it needs to be regenerated with acid or alkali. At this time, the liquid flows in the opposite direction to the product water, and the flow rate is called the regeneration flow rate. The operating flow rate and the regeneration flow rate differ significantly and are in opposite directions. However, if the flow rate of the water distribution device within the equipment remains constant, it is impossible to control the flow rates differently. This can lead to insufficient regeneration or excessive use of acid or alkali, and also increase the difficulty of treating the regeneration waste liquid. Utility Model Content

[0004] This utility model discloses a constant-pressure, bidirectional, controllable-flux water cap. The water cap includes a cap head, a cap rod, and a lower nut. The cap head is connected to the cap rod, and the cap rod is connected to the lower nut. A conical movable plug is installed inside the cap head. When liquid flows through the cap from bottom to top, the conical movable plug is pushed up, applying pressure to control the water flow. Liquid can pass through the cap. When liquid flows through the cap from top to bottom, the conical movable plug is pressed against the water channel opening of the cap rod by the water flow. The conical movable plug can be designed with different structures inside according to different flow rate requirements. This utility model solves the problem of large and reversed differences between the operating and regeneration flow rates of ion exchangers. However, when the flow rate of the water distribution device within the equipment remains constant, it is impossible to differentiate and control the flow rate, leading to insufficient regeneration or excessive use of acid and alkali, and increasing the difficulty of treating regeneration waste liquid.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A constant-pressure bidirectional controllable flow rate water cap includes a water cap head, a water cap rod, and a lower nut. The water cap head is connected to the water cap rod, and the water cap rod is connected to the lower nut. A conical movable plug is provided inside the water cap head. When liquid flows through the water cap from bottom to top, the conical movable plug is pushed up and applies pressure to the water flow to control the flow. Liquid can pass through the water cap. When liquid flows through the water cap from top to bottom, the conical movable plug is pressed against the water passage opening of the water cap rod by the water flow. Different structures can be designed inside the conical movable plug according to different flow rate requirements.

[0007] Further, the conical movable plug is a solid structure. When the liquid flows from top to bottom towards the water cap, the conical movable plug is pressed against the water channel opening of the water cap rod by the water flow, and the liquid cannot flow from top to bottom through the water cap.

[0008] Further, the conical movable plug has a fine hole inside. When the liquid flows from top to bottom towards the water cap, the conical movable plug is pressed against the water channel opening of the water cap rod by the water flow, and the liquid can flow through the fine hole and the water cap rod through the water cap.

[0009] This invention addresses the problem of a large and reversed difference between the operating and regeneration flow rates of an ion exchanger. It utilizes a conical movable plug with different internal structures designed to accommodate varying flow rates. However, without a constant water distribution system within the equipment, differential flow rate control is impossible, leading to insufficient regeneration or excessive acid / alkali usage, and increasing the difficulty of treating regeneration waste liquid.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Detailed implementation methods: such as Figures 1 to 3 As shown, this utility model provides a constant pressure bidirectional controllable flow 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.

[0021] The water cap head 3 is equipped with a conical movable plug 6. When the liquid flows from bottom to top through the water cap 2, the conical movable plug 6 is pushed up. The conical movable plug 6 gives pressure to the water flow to control the water flow and plays the role of controlling the water flow rate. This avoids the defect in products where the movable plug is a ball or an ellipsoidal ball, where the movable plug cannot control the water flow when the liquid flows from bottom to top through the water cap 2. This helps to make the water flow more uniform.

[0022] Liquid can pass through the water cap 2. When the liquid flows from top to bottom through the water cap 2, the conical movable plug 6 is pressed by the water flow at the water channel opening of the water cap rod 4. The conical movable plug 6 can be designed with different structures inside the movable plug 6 according to the needs of different flow rates.

[0023] Preferably, the conical movable plug 6 is a solid structure. When the liquid flows from top to bottom towards the water cap 2, the conical movable plug 6 is pressed against the water channel opening of the water cap rod 4 by the water flow, preventing the liquid from flowing from top to bottom through the water cap 2. This design is used in parts where the water channel is fully open when the liquid flows from bottom to top through the water cap 2, and fully closed when the liquid flows from top to bottom through the water cap 2.

[0024] Preferably, the conical movable plug 6 has a fine hole 7 inside. When the liquid flows from top to bottom towards the water cap 2, the conical movable plug 6 is pressed against the water channel opening of the water cap rod 4 by the water flow, and the liquid can flow through the fine hole 7 through the water cap rod 4 and across the water cap 2. This solution is used in locations where the water channel is fully open when the liquid flows from bottom to top through the water cap 2, and where a constant flow rate is required when the liquid flows from top to bottom. The diameter and number of fine holes 7 are designed according to the flow rate requirements.

[0025] This invention addresses the problem of a large and reversed difference between the operating and regeneration flow rates of an ion exchanger. It utilizes a conical movable plug 6, which allows for different structural designs within the plug to accommodate varying flow rates. However, without a constant water distribution device flow rate, differential flow rate control is impossible, leading to insufficient regeneration or excessive acid / alkali usage, and increasing the difficulty of treating regeneration waste liquid.

[0026] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. 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.
