Description

Technical Field

[0001] This utility model relates to the field of valve production and processing technology, specifically a three-way internal spiral ball valve. Background Technology

[0002] A three-way internal spiral ball valve, usually referring to a three-way internal thread ball valve, is a type of valve widely used in industrial automation and fluid control. The valve body adopts an internal thread design, which facilitates connection with pipelines and improves the convenience of installation and sealing performance.

[0003] However, when connecting a three-way ball valve to a pipeline, the pipeline is usually rotated and screwed into the inside of the three-way ball valve to make a threaded connection between the pipeline and the ball valve. When installing a three-way ball valve on an already installed pipeline, the pipeline needs to be disassembled, which increases the complexity of installation and makes maintenance more difficult, thus limiting its effectiveness.

[0004] The reason for this problem is that installation requires rotating the pipeline to connect it to the three-way ball valve's threads. If the pipeline is already installed, it cannot be installed directly; the pipeline must be disassembled to install the three-way ball valve, reducing installation efficiency. Furthermore, maintenance or replacement of the three-way ball valve requires first disassembling the connected pipeline. This not only increases maintenance complexity but also causes unnecessary interference or damage to the pipeline system, presenting limitations. Therefore, we propose a three-way internal spiral ball valve to solve these problems. Utility Model Content

[0031] Fixing blocks 21 are located at both ends of the three-way valve body 1. The fixing blocks 21 have internal threads, and the threads at both ends of the three-way valve body 1 are in opposite directions. Threaded pipe 22 is located on one side of the three-way valve body 1 and is threadedly connected to the three-way valve body 1. Sealing and fixing component 23 is located on one side of the threaded pipe 22 and is used to seal and fix the three-way valve body 1 when it is connected to the pipeline.

[0032] A valve stem 3 is provided above the three-way valve body 1, and a ball valve core is provided inside the three-way valve body 1. The valve stem 3 is connected to the ball valve core in a driving connection.

[0033] In this embodiment, when using the device, the pipe is pulled to both ends, the two ends of the three-way valve body 1 are aligned with the pipe to be installed, the pipe is released, and the end of the pipe is snapped into the inside of the fixing block 21. The three-way valve body 1 is rotated clockwise. Since the threads at both ends of the three-way valve body 1 are reversed, the clockwise rotation of the three-way valve body 1 can fix the pipes at both ends at the same time, ensuring the connection between the pipe and the three-way valve body 1.

[0034] Example 2

[0035] According to the appendix Figure 1 , 3 As shown in Figure 4, more specifically, based on Embodiment 1, it includes a three-way valve body 1, and the interior of the three-way valve body 1 is provided with an installation unit 2 for pipeline connection. The installation unit 2 includes a fixing block 21, a threaded pipe 22 and a sealing fastener 23.

[0036] Fixing blocks 21 are located at both ends of the three-way valve body 1. The fixing blocks 21 have internal threads, and the threads at both ends of the three-way valve body 1 are in opposite directions. Threaded pipe 22 is located on one side of the three-way valve body 1 and is threadedly connected to the three-way valve body 1. Sealing and fixing component 23 is located on one side of the threaded pipe 22 and is used to seal and fix the three-way valve body 1 when it is connected to the pipeline.

[0037] The sealing fastener 23 includes a first sealing ring 231 and a second sealing ring 232. The first sealing ring 231 is disposed on one side of the threaded pipe 22 and is slidably connected to the inside of the three-way valve body 1, with its end tightly fitted against the inner wall of the three-way valve body 1. The second sealing ring 232 is disposed on one side of the first sealing ring 231 and is fixedly assembled to the three-way valve body 1, with the first sealing ring 231 and the second sealing ring 232 abutting against each other. The sealing fastener 23 also includes a first flange 233 and a second flange 234. The first flange 233 is fixedly assembled to the end of the threaded pipe 22; the second flange 234... 4. The sealing fastener 23 is disposed on one side of the first flange 233, and the ends of the first flange 233 and the second flange 234 abut against each other. The sealing fastener 23 also includes a sealing groove 235 and a sealing ring 236. The sealing groove 235 is opened inside the first flange 233. The sealing ring 236 is fixedly assembled at the end of the second flange 234 and is movably snapped into the inside of the sealing groove 235. The sealing fastener 23 also includes a fastening bolt 237. The fastening bolt 237 is disposed inside the first flange 233 and the second flange 234. The fastening bolt 237 is threadedly connected to the first flange 233 and is distributed in a ring array.

[0038] In this embodiment, when it is necessary to connect the pipeline on one side, grasp the threaded pipe 22 and rotate it counterclockwise, causing the threaded pipe 22 to move to one side, which in turn drives the first flange 233 to move to one side simultaneously. The second flange 234 is fixed on the pipeline. The threaded pipe 22 continues to move to one side, so that the ends of the first flange 233 and the second flange 234 abut against each other, causing the sealing ring 236 to be inserted into the sealing groove 235. At this time, stop rotating and pass the fastening bolt 237 through the second flange 234 in sequence and thread it to the first flange 233, thus completing the connection between the pipeline on one side and the three-way valve body 1. The function of the first sealing ring 233 and the second sealing ring 234 is to prevent fluid from flowing out along the gap between the threaded rods, ensuring the normal use of the device and meeting the user's needs.
