DETAILED DESCRIPTION

[0030] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0031] Referring to Figure 1 And Figure 2 An embodiment provided by the utility model: a three-way valve convenient to install, including three -way valve body 1, three -way valve body 1 three ends are fixedly connected with connecting pipe 3, and connecting pipe 3 is internally provided with connecting assembly;

[0032] The connecting assembly comprises a steel ball 7 rotatably connected inside the connecting pipe 3, which serves to realize the fixed connection of the pipe 2 and the connecting pipe 3. When the pipe 2 is inserted into the connecting pipe 3, the steel ball 7 is embedded into the clamping groove 4 in the pipe 2, thereby locking the position of the pipe 2 and ensuring the stable connection. The pipe 2 is slidably connected inside the connecting pipe 3, and the pipe 2 is internally provided with the clamping groove 4 for receiving the steel ball 7, thereby enhancing the firmness of the connection and preventing the pipe 2 from being separated from the connecting pipe 3. The outer wall of the connecting pipe 3 is slidably connected with a limiting ring 6, and the outer wall of the limiting ring 6 is fixedly connected with a dismounting sleeve 5. The limiting ring 6 serves to ensure that the steel ball 7 can be correctly embedded into the clamping groove 4 and to ensure the tightness and stability of the connection through the resetting function of the limiting ring 6. The outer wall of the connecting pipe 3 is provided with a resetting assembly, which serves to provide the necessary tension through the first spring 9 to push the limiting ring 6 to reset and to ensure the reliability during the connection process. The connecting pipe 3 is internally provided with a sealing assembly, which comprises a sealing ring I 8 fixedly connected to the inner wall of the connecting pipe 3. The inner wall of the sealing ring I 8 is in close contact with the outer wall of the pipe 2. The sealing ring I 8 serves to ensure the good sealing between the pipe 2 and the connecting pipe 3 and to prevent fluid leakage. The steel ball 7 is embedded into the clamping groove 4, thereby ensuring that the steel ball 7 can be firmly fixed in the clamping groove 4 during the connection and achieving the effect of stable connection. The resetting assembly comprises the first spring 9, which is sleeved on the outer wall of the connecting pipe 3. One end of the first spring 9 is fixedly connected to one side of the limiting ring 6, and the other end of the first spring 9 is fixedly connected to the inner wall of the connecting pipe 3. The first spring 9 serves to automatically push the limiting ring 6 to reset through the tension, thereby ensuring that the limiting ring 6 can quickly return to the original position after the dismounting sleeve 5 is loosened, and ensuring the safety and stability of the connection. The sealing assembly comprises the sealing ring I 8 fixedly connected to the inner wall of the connecting pipe 3. The inner wall of the sealing ring I 8 is in close contact with the outer wall of the pipe 2, thereby ensuring the sealing of the connection part and preventing liquid leakage. The pipe 2 is internally fixedly connected with a top block 10, which serves to provide the positioning function required during installation and to ensure the stable position of the pipe 2 in the connecting pipe 3.

[0033] Specifically, when the three-way valve body 1 is connected with the pipe 2, the limiting ring 6 is first driven to slide to the left by the movement of the dismounting sleeve 5, thereby opening the connecting channel and creating conditions for the insertion of the pipe 2. At this time, the pipe 2 is easily inserted into the connecting pipe 3, and the steel ball 7 inside the connecting pipe 3 is automatically embedded into the clamping groove 4, thereby ensuring the stable combination of the pipe 2 and the connecting pipe 3. With the loosening of the dismounting sleeve 5, the tension of the first spring 9 immediately acts to quickly reset the limiting ring 6, and the limiting ring 6 is firmly attached to the outer wall of the steel ball 7, thereby preventing the steel ball 7 from sliding out of the clamping groove 4 and ensuring the firmness and reliability of the connection. The sealing ring I 8 between the pipe 2 and the connecting pipe 3 provides a reliable sealing effect, thereby effectively preventing fluid leakage.

[0034] Referring to Figure 3The inside of the connecting pipe 3 is fixedly connected with a fixed column 11. The fixed column 11 provides stable support and positioning, ensures that the pressing column 13 can slide therein, and effectively cooperates with other components. The inside of the fixed column 11 is provided with a cavity 12. The cavity 12 provides sufficient space for the sliding of the pressing column 13, ensures that the pressing column 13 is not hindered during movement, and guarantees smooth operation. The inside of the fixed column 11 is slidably connected with the pressing column 13. The pressing column 13 drives the limiting plate 14 and other components by sliding when the pipeline 2 is separated from the connecting pipe 3, and realizes the self-sealing function. The outer wall of the pressing column 13 is fixedly connected with the limiting plate 14. The limiting plate 14 limits the movement range of the pressing column 13, ensures that the pressing column 13 does not move excessively during operation, and thus maintains the stability and functional reliability of the device. The outer wall of the fixed column 11 is sleeved with a second spring 15. The second spring 15 provides sufficient elastic force, so that the pressing column 13 can return to the initial position. One end of the second spring 15 is fixedly connected to one side of the limiting plate 14, and the other end is fixedly connected to the inside of the fixed column 11, which ensures that the tension of the spring can effectively push the pressing column 13 to reset, and ensures the reliability of the sealing function. The outer wall of the pressing column 13 is fixedly connected with a sealing ring two 16. The sealing ring two 16 ensures the sealing between the pressing column 13 and the fixed column 11, prevents liquid or gas leakage, and ensures the sealing effect during connection. The outer wall of the sealing ring two 16 is in close contact with the outer wall of the fixed column 11, which ensures that the sealing ring two 16 can provide uniform pressure and maintain the sealing effect. One end of the pressing column 13 is fixedly connected with a baffle 17. The baffle 17 is in close contact with one end of the fixed column 11, and can effectively prevent liquid leakage during the sliding of the pressing column 13, and ensure the stability of the sealing state. One side of the baffle 17 is in close contact with one end of the fixed column 11. Through this structure, the baffle 17 can cooperate with the pressing column 13 to ensure the sealing during disassembly or installation, and achieve the effect of preventing liquid leakage.

[0035] Specifically, after the pipeline 2 is installed, the pressing column 13 is accurately pushed into the fixed column 11 by the action of the top block 10, forcing the baffle 17 to separate from the sealing ring two 16 and the fixed column 11, thereby leaving space for the flow of liquid, so that the liquid can smoothly enter the inside of the fixed column 11 and flow out from the cavity 12. When disassembly is required, the pipeline 2 is separated from the connecting pipe 3. At this time, the baffle 17 and the sealing ring two 16 are supported by the elastic force of the second spring 15, and maintain their original positions. With the action of the limiting plate 14, the pressing column 13 is automatically brought back to the reset position, so that the baffle 17 and the sealing ring two 16 are tightly recombined in the inside of the fixed column 11, thereby realizing the self-sealing function.

[0036] Working principle: when using the convenient installation of the three-way valve, first, the three-way valve body 1 is connected with the pipeline 2, the disassembly sleeve 5 drives the limiting ring 6 to move left, then the pipeline 2 is inserted into the connecting pipe 3, the steel ball 7 in the connecting pipe 3 is embedded in the clamping groove 4, then the disassembly sleeve 5 is loosened, the limiting ring 6 is reset by the tension of the first spring 9 to make the limiting ring 6 adhere to the outer wall of the steel ball 7, preventing the steel ball 7 from sliding out of the clamping groove 4, the pipeline 2 and the connecting pipe 3 are sealed by the sealing ring 8, achieving the effect of convenient connection;

[0037] Then, after the pipeline 2 is installed, the pressing column 13 is pushed into the fixed column 11 by the top block 10, the baffle 17 is separated from the sealing ring 16 and the fixed column 11, and then the liquid can enter the fixed column 11 and flow out of the cavity 12, when disassembling, the pipeline 2 is separated from the connecting pipe 3, the baffle 17 and the sealing ring 16 are supported by the tension of the second spring 15, the pressing column 13 is reset by the limiting plate 14, the baffle 17 and the sealing ring 16 adhere to the inside of the fixed column 11, achieving the effect of self-sealing.

[0038] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be contained in the protection scope of the utility model.
