Description

Technical Field

[0001] This utility model relates to the field of liquid distribution and pressure control technology, specifically a diversion device for water supply and drainage. Background Technology

[0002] A water supply and drainage diversion device is a device installed on the main water supply and drainage pipeline to distribute a single water flow to multiple branches, thereby regulating and controlling the direction, flow rate, or pressure of the water flow.

[0003] The prior art patent document with publication number CN222730693U provides a water supply and drainage diversion device, including a diversion main pipe, a diversion box, a diversion head, a first connecting component, a diversion branch pipe, and a second connecting component. This water supply and drainage diversion device can effectively reduce the water flow pressure by providing a diversion box with an equilateral triangular structure at the end of the diversion main pipe, so as to divert the water flow to multiple water supply points. The first connecting component facilitates the assembly or disassembly of the diversion branch pipe, and the second connecting component can strengthen the connection between the diversion branch pipe and the diversion box. Compared with the traditional diversion method, this device has a detachable design, which allows users to easily remove the old diversion branch pipe and install the new diversion branch pipe, thereby greatly reducing maintenance costs and reducing the construction scope.

[0004] Although the device has many beneficial effects, it still has the following problems: it requires the simultaneous configuration of circular sealing rings and irregular sealing strips, and the use of clamps to achieve three-level sealing. During installation, the positioning groove and protrusion must be precisely aligned. During maintenance, six fasteners, including screws and the second nut, need to be removed. The sealing structure is redundant and lacks pressure self-adaptation capability. Furthermore, the first connecting component requires the sequential assembly of the connecting column, mounting plate, and first nut. The second connecting component has a separate clamp structure. A single branch pipe connection requires 12 operation steps, resulting in low installation and connection efficiency. Utility Model Content

A conical sealing ring with double bevels of 30° and 45° is designed inside the circumference of the diversion joint, and this ring, combined with the compensation groove built into the diversion joint, forms a dynamic sealing structure, thereby achieving pressure-adaptive sealing. Finally, a three-stage sealing structure is formed by the sealing ring and clamp structure embedded in the side wall of the diversion joint. Simultaneously, a quick-connect mechanism is designed, using a square slider and an L-shaped groove to achieve an insertion-rotation connection. A positioning ball and a hemispherical positioning groove are used for connection positioning and to form a mechanical interlock. Finally, a clamp provides final axial limiting, ensuring connection strength while significantly reducing connection operation steps and improving connection and installation efficiency.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a diversion device for water supply and drainage, including:

[0035] Please see Figures 1-5This embodiment of a water supply and drainage diversion device includes a main pipe 100 for connecting to external water supply and drainage equipment. A diversion box 200 is welded to the output end of the side wall of the main pipe 100 for storing water and diverting it. A diversion connector 300 is welded to the side wall of the diversion box 200 for connecting to a diversion pipe 400. The diversion connector 300 includes a sealing ring 320 and a sealing ring 350. A diversion pipe 400 is fixedly connected to the side wall of the diversion connector 300. The diversion pipe 400 includes a slider 420 and a positioning ball 440. A clamp 500 is sleeved on the outer circumference of the diversion pipe 400 to improve connection stability and sealing.

[0036] It is worth noting that, in order to improve the connection sealing performance, specifically, four sliding grooves 310 are opened on the inner circumference of the diverter 300, and a sealing ring 320 is bonded inside the circumference of the diverter 300 to form a primary seal at the joint between the diverter 300 and the diverter pipe 400. Multiple positioning grooves 340 are opened on the inner circumference of the diverter 300, and a sealing ring 350 is embedded in the side wall of the diverter 300 to form a secondary sealing joint at the contact surface between the diverter 300 and the diverter pipe 400.

[0037] Next, to facilitate the connection of the diverter tube 400, specifically, a connecting tube 410 is welded inside the circumference of the diverter tube 400. Four sliders 420 are integrally formed on the outer wall of the connecting tube 410 and locked in conjunction with the sliding groove 310. Four insertion holes are opened on the outer wall of the diverter tube 400. A spring 430 is fixedly connected to the bottom of the inner cavity of the insertion hole for the positioning ball 440 to reset. The positioning ball 440 is fixedly connected to the top of the spring 430 and positioned in conjunction with the positioning groove 340.

[0038] Meanwhile, in order to improve the connection stability of the clamp 500, specifically, the clamp 500 includes a retaining ring 510. The retaining ring 510 has two limiting strips 520 integrally formed on its inner circumference, which axially limit the disc structure protruding from the side wall of the diverter 300 and the disc structure on the outer circumference of the diverter pipe 400.

[0039] Furthermore, to facilitate the sliding locking of the slider 420 and the positioning of the positioning ball 440, specifically, a compensation groove 330 is provided on the inner circumference of the diversion joint 300. When the sealing ring 320 is compressed and radially expands and deforms, a radial expansion compensation gap is generated. The compensation groove 330 has a square structure, the sliding groove 310 has an L-shaped structure, and the positioning groove 340 has a hemispherical structure, which facilitates the insertion of the positioning ball 440.

[0040] It is worth noting that, in order to improve the sealing performance of the sealing ring 320, specifically, the sealing ring 320 is a wedge-shaped sealing ring 320, one of the inclined surfaces of the sealing ring 320 has an inclination angle of 30 degrees, and the other inclined surface of the sealing ring 320 has an inclination angle of 45 degrees, forming a pressure-increasing sealing gradient. The sealing ring 350 has a triangular structure and is a metal-reinforced rubber composite sealing ring. The triangular structure of the sealing ring 350 can control and reduce the compression of the sealing ring 350.

[0041] Finally, to facilitate the sliding connection of the slider 420, specifically, the slider 420 has a square structure, the size of the slider 420 matches that of the groove 310, and the outer circumference of the connecting pipe 410 is in close contact with the inner circumference of the diverter 300, further improving the connection sealing performance.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Combination Figures 1-5 The specific usage process of the water supply and drainage diversion device of this embodiment is as follows:

[0044] 1. Connect the main pipe 100 of the diversion device to the water supply and drainage equipment. Then, hold the connection port of the diversion pipe 400 and align the slider of the connecting pipe 410 with the slide groove 310. Then, insert it horizontally to the bottom and rotate the diversion pipe 400. When the diversion pipe 400 rotates, it drives the positioning ball 440 to make a circular motion. When the positioning ball 440 receives the push force of the spring 430 and is stuck in the positioning groove 340, the positioning ball 440 will make a sound due to the collision. When the user hears the sound, it means that the initial connection between the diversion pipe 400 and the diversion connector 300 is completed.

[0045] 2: Then use clamp 500 to fit the two disc-shaped protrusions of the shunt connector 300 and the shunt pipe 400, and ensure that the limiting strip 520 axially limits the shunt connector 300 and the shunt pipe 400. Then complete the connection between the shunt pipe 400 and the shunt connector. After that, the output end of the shunt pipe 400 can be connected to other devices.

[0046] 3: When this type of diversion device is used, the sealing ring 320, the sealing ring 350 and the clamp 500 form a three-stage sealing structure. When water flows through the diversion pipe 400 and the pressure is high, the sealing ring 320 is compressed and undergoes radial expansion deformation, and the sealing ring 350 also expands and deforms, together forming a dynamic sealing structure to ensure the sealing performance between the diversion joint 300 and the diversion pipe 400.

[0047] 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.
