Description

Technical Field

[0001] This utility model belongs to the field of pressure tank technology, and specifically relates to a water-prevention mechanism for self-cleaning, water-prevention pressure tanks. Background Technology

[0002] Traditional pressure tanks mostly use rubber diaphragms to separate air and water. Because there is a blind zone near the edge of the tank at the inlet, and the water flow velocity at the inlet is low, the water flow cannot effectively impact the air, thus forming a stagnant water zone. Over time, the stagnant water zone accelerates the dissolution and corrosion of the diaphragm, while also breeding microorganisms, further damaging the molecular structure of the diaphragm material and causing diaphragm damage.

[0003] Therefore, how to solve the defects in the existing technology has become one of the urgent problems to be solved in the field of pressure tank technology. Utility Model Content

[0004] In view of the problems existing in the background art, the present invention provides a water-prevention mechanism for a self-cleaning water-prevention pressure tank, including the water-prevention mechanism installed at the water inlet end of the pressure tank. The water-prevention mechanism is generally disc-shaped, and the outer wall of the water-prevention mechanism has a conical surface. The inner wall of the water-prevention mechanism is welded with reinforcing ribs integrally formed therewith. The reinforcing ribs are arranged in multiple sets and extend continuously towards the middle part, and a flow divider plate integrally formed therewith is provided.

[0005] Optionally, the anti-dampness mechanism has filter holes on its end face, and the filter holes are arranged in multiple sets and are evenly distributed around the top end face of the anti-dampness mechanism.

[0006] Optionally, the side end face of the reinforcing rib is welded to the conical inner wall of the anti-dampness mechanism.

[0007] Optionally, the diverter plate intersects with the reinforcing rib and forms an included angle β, which is 75°-135°.

[0008] Optionally, there is an included angle α between two adjacent sets of the diverter plates, and the included angle α is 55°-130°.

[0009] Optionally, the inner wall of the anti-dead-water mechanism is provided with a drainage pipe.

[0010] An inlet is provided on the end face of the anti-stagnant water mechanism located away from the drainage pipe.

[0011] The drainage tube is hollow.

[0012] Optionally, a manifold is provided at the outlet end of the drainage tube, which is located away from the interface, and is connected thereto.

[0019] Optionally, the swirl fan blades are arranged in multiple sets.

[0020] And they are evenly distributed along the circumference of the connector.

When the high-speed water jet impacts the diversion plate, the water flow forms a bidirectional reflected flow after being impacted by the diversion plate. Moreover, the channel cross-section formed by the 115° included angle α has a V-shaped gradual change, which can effectively increase the water flow impact area, thereby effectively reducing the formation of dead water areas and extending the service life of the diaphragm.

[0039] Example 1

[0040] like Figure 1-3 As shown, this embodiment provides a water-prevention mechanism 100 for a self-cleaning water-prevention pressure tank. The water-prevention mechanism 100 is installed at the water inlet end of the pressure tank, and the water-prevention mechanism 100 is generally disc-shaped. The outer wall of the water-prevention mechanism 100 has a conical surface 10, so that when the water-prevention mechanism is installed at the water inlet end of the pressure tank, it has good sealing performance.

[0041] The anti-dampness mechanism 100 has filter holes 20 on its end face. The filter holes 20 are arranged in multiple sets and are evenly distributed circumferentially along the top end face of the anti-dampness mechanism 100. By adding filter holes, particulate matter can be effectively intercepted.

[0042] Furthermore, the inner wall of the anti-dampness mechanism 100 is welded with an integrally formed reinforcing rib 40, and the side end face of the reinforcing rib 40 is welded to the conical inner wall of the anti-dampness mechanism 100. The integral reinforcing rib 40 improves the overall rigidity of the mechanism and prevents deformation caused by the impact of high-pressure water flow.

[0043] Furthermore, the reinforcing ribs 40 are arranged in multiple groups, extending continuously towards the middle part, and are provided with a diversion plate 50 integrated with them. The diversion plate 50 intersects with the reinforcing ribs 40 and forms an included angle β, which is 75°-135°, preferably 90°.

[0044] Furthermore, there is an included angle α between two adjacent sets of the diversion plates, and the included angle α is 55°-130°. When the included angle β is 90° and the included angle α is 115°, water flows into the filter hole at high speed. When the high-speed water jet impacts the diversion plate, the water flow is impacted by the diversion plate and forms a bidirectional reflected flow. The channel cross-section formed by the 115° included angle α has a V-shaped gradual change, which can effectively increase the water flow impact area, thereby effectively reducing the formation of dead water areas and extending the service life of the diaphragm.

[0045] Example 2

[0046] In practical applications, while the angled design of the flow divider (β = 90°, α = 115°) optimizes the water flow distribution, the confluence point is prone to damage under the impact of the water flow. Therefore, Embodiment Two further improves upon this design. Please refer to [link / reference]. Figure 3 The inner wall of the anti-dampness mechanism 100 is provided with a drainage pipe 60, and an inlet is provided on the end face of the anti-dampness mechanism 100 away from the drainage pipe. The drainage pipe 60 is hollow to facilitate the entry of fluid into the drainage pipe 60.

[0047] Furthermore, a confluence end 701 is provided at the outlet end of the drain pipe 60 away from the interface 30 and is connected thereto. At least two sets of opposing swirl plates 702 are welded on the outer wall of the confluence end 701. The swirl plates 702 are C-shaped and the other end of the swirl plates 702 is welded to the connecting shaft 704.

[0048] Furthermore, the vortex plate is made of lightweight stainless steel and has a hollow interior, and it is not connected to the confluence end 701. This is to prevent water from entering the vortex plate through the confluence end.

[0049] In this embodiment, the swirl plate 702 enables water to flow out of the filter hole 20 at high speed, and the swirl plate increases the water flow impact area, reducing the formation of stagnant water areas.

[0050] Furthermore, the confluence end 701 has a jet port 706, and a swirl fan blade 705 is installed on the end face of the connecting shaft 704 facing the jet port 706, and the swirl fan blade 705 is connected to the connecting shaft 704 by a connector.

[0051] Furthermore, the swirl fan blades 705 are arranged in multiple groups and are evenly distributed along the circumference of the connector. The end faces of the swirl fan blades near the connector and the end faces of the swirl fan blades away from the connector are inclined, so that the swirl fan blades are slightly tilted.

[0052] In this embodiment, a portion of the water flows out at high speed through the filter holes and the impact area of ​​the water flow is increased by the swirl plate, while another portion of the water flow is transported to the confluence end 701 through the diversion pipe 60 and is ejected at high speed through the jet holes to impact the swirl fan blades. This allows the water flow to be effectively dispersed by the swirl fan blades, thereby satisfying the impact surface of the water flow, preventing the formation of dead water areas, and avoiding damage to the diversion plate of the anti-dead water mechanism.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
