Description

Technical Field

[0001] This utility model relates to the field of valve assembly and disassembly technology, specifically to a quick-installation three-way ball valve for multi-directional fluid control. Background Technology

[0002] A three-way ball valve is a valve used to control the flow direction of fluid. Its core component is a ball with a through hole, which can rotate within the valve body to change the flow path of the fluid between the three channels, enabling operations such as fluid diversion, merging, and flow direction switching.

[0003] A utility model patent with publication number CN219453016U discloses a three-way internal spiral ball valve, including a three-way internal spiral ball valve body and a pipeline. The pipeline is located on both sides of the three-way internal spiral ball valve body, and connecting blocks are fixedly connected to both sides of the three-way internal spiral ball valve body. A connector is fixedly connected to the right side of the pipeline, and a limit block is fixedly connected to the left side of the connector surface. A fixing block is movably connected to the top of the limit block, and a sealing ring is fixedly connected to the left side of the inner wall of the connecting block. The left side of the connecting block surface is threadedly connected to the right side of the inner wall of the fixing block. The disadvantage is that the sealing performance of the connector and pipeline is insufficient when the fixing block is rotated to connect the connector and the pipeline. The sealing contact between the connector and the pipeline depends on the thread tightening force, which cannot achieve a high-strength seal. Moreover, rotating the connector is very laborious. Therefore, a quick-installation three-way ball valve for multi-directional fluid control is proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Please see Figure 1-5A quick-installation three-way ball valve for multi-directional fluid control includes a three-way valve body 1 and a valve switch 2. The three-way valve body 1 is provided with three valve pipes 3. Each valve pipe 3 has a first flared structure 302 on the side away from the three-way valve body 1. The valve pipe 3 is connected to a connecting pipe 4 through the first flared structure 302. The other end of the connecting pipe 4 is used to connect to an external water pipe or other device. A sleeve 5 is fitted on the valve pipe 3. The outer surface of the valve pipe 3 has an external thread 301. The inner wall of the sleeve 5 has an internal thread 501. The external thread 301 and the internal thread 501 cooperate with each other. A retaining ring 401 is provided on the connecting pipe 4. A locking component 6 is rotatably provided on the first flared structure 302 of the valve pipe 3. When the valve pipe 3 rotates, the locking component 6 can abut against the retaining ring 401 on the side away from the three-way valve body 1 and lock the connecting pipe 4 and the valve pipe 3.

[0030] In this embodiment, each valve pipe 3 is provided with at least three sets of locking components 6, which are equidistantly arranged circumferentially about the axis of the valve pipe 3. The design of at least three sets and equidistant circumferential arrangement can apply uniform locking force to the connecting pipe 4 from multiple directions, ensuring a stable connection between the connecting pipe 4 and the valve pipe 3, effectively preventing loosening or leakage under fluid pressure, and greatly improving the reliability of the connection.

[0031] In this embodiment, each locking assembly 6 includes a fixing block 601 and a locking strip 602. The fixing block 601 is fixedly installed on the outer surface of the first flared structure 302, and one side of the locking strip 602 is rotatably connected to the fixing block 601 via a rotating shaft 6023. The fixing block 601 provides a stable support point for the locking strip 602, and the locking strip 602 is rotatably connected to the fixing block 601 via the rotating shaft 6023, allowing the locking strip 602 to rotate flexibly under the action of the sleeve 5, thereby achieving the locking action on the connecting pipe 4. The structure is simple and the operation is reliable.

[0032] In this embodiment, a second flared structure 502 is provided at the end of the sleeve 5 away from the three-way valve body 1. The second flared structure 502 covers the outside of the fixing block 601, and the open end of the second flared structure 502 abuts against the outer surface of the locking strip 602. The second flared structure 502 covers the outer side of the fixing block 601 without affecting the rotation of the locking strip 602, thus protecting the fixing block 601. At the same time, its open end abuts against the outer surface of the locking strip 602, which can push the locking strip 602 to rotate when the sleeve 5 moves, thereby realizing the locking function. The design is ingenious and practical.

[0033] It should be noted that the second flared structure 502 increases the diameter of the sleeve 5, making it easier for operators to rotate the sleeve 5 with less effort. At the same time, the outer surface of the second flared structure 502 is provided with anti-slip strips to further reduce the difficulty of disassembling and assembling the device, making it more convenient to use.

[0034] In this embodiment, the opening end of the second flared structure 502 is provided with a rounded corner 503. The design of the rounded corner 503 makes the contact between the opening end of the second flared structure 502 and the outer surface of the locking strip 602 smoother, reduces friction when pushing the locking strip 602 to rotate, making the operation easier and less strenuous, and also reduces wear between components and extends service life.

[0035] In this embodiment, the locking bar 602 includes a strip-shaped rod 6021 and a locking block 6022 fixedly formed on the strip-shaped rod 6021. The locking block 6022 is located on the side of the strip-shaped rod 6021 near the fixing block 601, and abuts against the side of the retaining ring 401. The strip-shaped rod 6021, as the main body of the locking bar 602, provides sufficient strength and length to push the connecting tube 4 to move, while the locking block 6022 can more accurately abut against the side of the retaining ring 401, effectively transmitting the force to the connecting tube 4 and ensuring the locking effect.

[0036] It should be noted that the position of the locking block 6022 close to the side of the fixing block 601 makes the locking strip 602 a force-saving lever structure. By rotating the sleeve 5, the sleeve 5 moves to the opening to abut and push the locking strip 602. The locking strip 602 rotates along the fixing block 601, so that the locking block 6022 abuts and pushes the retaining ring 401 with greater force, thereby amplifying the locking effect and enhancing the sealing performance.

[0037] In this embodiment, a water-stop ring 7 is provided at the connection between valve pipe 3 and connecting pipe 4. The water-stop ring 7 is an annular sealing element. As a key sealing component, the water-stop ring 7 can effectively prevent fluid leakage from the connection between valve pipe 3 and connecting pipe 4. Its annular design allows it to seal the connection part from all directions, providing an important guarantee for the reliable operation of the ball valve.

[0038] In summary, this multi-directional fluid control quick-installation three-way ball valve, when the sleeve 5 is rotated towards the locking assembly 6, causes the opening end of the second flared structure 502 to abut against the outer surface of the locking strip 602, thus pushing the locking strip 602 to rotate closer to the connecting pipe 4. The rotating locking strip 602 compresses the retaining ring 401, causing the connecting pipe 4 to move towards the valve pipe 3, thereby achieving a rapid sealing connection. Traditional ball valves use threaded transmission for direct sealing, which is not only laborious but also makes it difficult to guarantee a tight seal. In contrast, the quick-installation three-way ball valve of this device ensures a tight connection during rapid installation, greatly enhancing the sealing effect and overcoming the shortcomings of existing ball valves in sealing and installation.

[0039] The working principle of this multi-directional fluid control quick-install three-way ball valve is as follows: During installation, first connect the connecting pipe 4 and the valve pipe 3 through the first flare structure 302. Then rotate the sleeve 5 on the valve pipe 3. Because the outer surface of the valve pipe 3 has external threads 301 and the inner wall of the sleeve 5 has internal threads 501, the two cooperate to move the sleeve 5 toward the locking assembly 6. The second flare structure 502 at one end of the sleeve 5 covers the outside of the fixing block 601, and its open end abuts against the outer surface of the locking strip 602. The open end is rounded 503, which can reduce the friction when pushing the locking strip 602 to rotate. As the sleeve 5 moves, it pushes the locking strip 602 to rotate around the pivot 6023 of the fixing block 601 toward the side closer to the connecting pipe 4. The bar-shaped rod 6021 of the locking bar 602 provides sufficient strength, and the locking block 6022 precisely abuts against the side of the retaining ring 401 on the connecting pipe 4. The position of the locking block 6022 makes the locking bar 602 form a force-saving lever structure, amplifying the locking effect. The locking bar 602 rotates and squeezes the retaining ring 401, driving the connecting pipe 4 to move towards the valve pipe 3. At the same time, the water-stop ring 7 at the connection between the valve pipe 3 and the connecting pipe 4 plays a sealing role to prevent fluid leakage, ultimately achieving a fast, tight, and reliable sealed connection between the connecting pipe 4 and the valve pipe 3.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
