Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a valve side-operating structure. Background Technology

[0002] A valve is a device used to control the flow of fluids, regulating flow rate and pressure by changing the area of ​​the passage. They are widely used in various industrial fields, including petroleum, chemical, power, and water treatment. Valves typically consist of a valve body, valve cover, valve disc, valve stem, and seals. The valve body is the main body of the valve, containing internal passages and cavities for fluid flow.

[0003] Traditional valves typically have their inlet and outlet pipes installed at opposite ends of the valve body. While this meets basic fluid control requirements, in space-constrained situations, traditional valves can occupy a significant amount of installation space, leading to layout difficulties. Therefore, we propose a valve side-mounted operation structure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a valve side-lying operation structure.

[0005] This utility model is achieved using the following technical solution: a valve side-lying operating structure, including a valve body, a water flow channel provided on the inner wall of the valve body, an inlet pipe fixedly connected to the left end of the valve body, an outlet pipe fixedly connected to the left end of the valve body, a groove opened on the right end of the valve body, a fixing plate provided inside the groove, threaded rods threadedly connected to the four corners of the fixing plate, a valve core provided in the middle of the water flow channel, a valve stem fixedly connected to the right end of the valve core, a worm gear fixedly connected to the surface of the valve stem, a worm engaging with the inner wall of the worm gear, mounting brackets rotatably connected to both ends of the worm, an extension rod fixedly connected to one end of the worm, and a handwheel fixedly connected to the end of the extension rod away from the worm.

[0006] With the above technical solution, rotating the handwheel drives the extension rod to rotate, causing the worm gear to rotate, which in turn drives the worm wheel to rotate, causing the valve stem to rotate, which in turn drives the valve core to rotate on the inner wall of the valve body. Since the valve core is spherical, the water flow channel is closed, making operation simple and quick. The self-locking characteristics of the worm gear and worm wheel can effectively prevent the valve from opening or closing on its own under fluid pressure. The spherical design of the valve core allows it to fit tightly against the inner wall of the water flow channel when closed, ensuring good sealing. The side of the fixing plate near the valve core has a groove that matches the valve core, allowing the valve core to rotate within it.

[0007] As a further improvement to the above solution, the water flow channel is U-shaped, and both the inlet pipe and the outlet pipe are connected to the water flow channel.

[0008] By installing the inlet and outlet pipes on one side of the valve body, the water inlet and outlet are both on one side, making the overall structure more compact and saving installation space. The U-shaped water flow channel design reduces the resistance when the fluid passes through, thus improving the fluid flow efficiency.

[0009] As a further improvement to the above solution, flanges are fixedly connected to the surfaces of both the inlet pipe and the outlet pipe.

[0010] The above technical solution facilitates connection to external fluid pipelines via flanges on the surfaces of the inlet and outlet pipes, allowing fluid to enter the interior of the inlet pipe.

[0011] As a further improvement to the above solution, the size of the fixing plate is adapted to the size of the groove, and the left end of the threaded rod passes through the fixing plate and is threadedly connected to the inner wall of the valve body.

[0012] The above technical solution involves a sealing material inside the groove, which ensures that the fixing plate remains sealed after installation, preventing fluid from leaking out through gaps. The fixing plate is installed via a threaded rod, facilitating subsequent disassembly to remove the valve core for maintenance or replacement.

[0013] As a further improvement to the above solution, the surface of the valve stem is rotatably connected to the inner wall of the fixing plate, and the right end of the valve stem passes through the fixing plate and is rotatably connected to a fixing bracket.

[0014] The above technical solution provides stable support for the valve stem through the fixing plate and fixing frame, ensuring smooth operation of the valve stem.

[0015] As a further improvement to the above solution, the left end of the fixing frame is fixedly connected to the right end of the fixing plate.

[0016] As a further improvement to the above solution, one end of the mounting bracket is fixedly connected to the inner wall of the fixing bracket.

[0017] The above technical solution uses a fixing bracket to install and fix the mounting bracket, ensuring stability during use.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model features a valve body, an inlet pipe, and an outlet pipe. Specifically, the inlet and outlet pipes are installed on one side of the valve body, making both the water inlet and outlet on the same side. This results in a more compact overall structure, saving installation space and making it suitable for space-constrained applications. The U-shaped water flow channel design reduces resistance when the fluid passes through, thus improving fluid flow efficiency.

[0020] This utility model, by setting a fixing plate and a threaded rod, specifically by removing the threaded rod to remove the fixing plate, facilitates subsequent maintenance or replacement of the valve core, thus improving the convenience of subsequent maintenance. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example:

[0030] Please combine Figure 1-5The valve side-operated structure of this embodiment includes a valve body 1, a water flow channel 2 provided on the inner wall of the valve body 1, an inlet pipe 3 fixedly connected to the left end of the valve body 1, an outlet pipe 4 fixedly connected to the left end of the valve body 1, a groove 5 opened on the right end of the valve body 1, a fixing plate 6 provided inside the groove 5, threaded rods 7 threadedly connected to the four corners of the fixing plate 6, a valve core 8 provided in the middle of the water flow channel 2, a valve stem 9 fixedly connected to the right end of the valve core 8, a worm gear 10 fixedly connected to the surface of the valve stem 9, a worm 11 meshing with the inner wall of the worm gear 10, and the worm... The two ends of 11 are rotatably connected to mounting brackets 12. One end of the worm gear 11 is fixedly connected to an extension rod 13. The end of the extension rod 13 away from the worm gear 11 is fixedly connected to a handwheel 14. Fluid enters the water flow channel 2 inside the valve body 1 through the inlet pipe 3. Since the water flow channel 2 is U-shaped, the fluid flows out through the outlet pipe 4 after passing through the water flow channel 2. By installing the inlet pipe 3 and the outlet pipe 4 on one side of the valve body 1, the water inlet and outlet are both on one side, making the overall structure more compact and saving installation space, which is suitable for space-constrained occasions.

[0031] The water flow channel 2 is U-shaped, and both the inlet pipe 3 and the outlet pipe 4 are connected to the water flow channel 2. The design of the U-shaped water flow channel 2 makes the resistance of the fluid smaller when it passes through, thus improving the fluid flow efficiency.

[0032] Flanges are fixedly connected to the surfaces of both the inlet pipe 3 and the outlet pipe 4, and the inlet pipe 3 and the outlet pipe 4 are connected to the external fluid pipeline through the flanges, so that the fluid can enter the interior of the inlet pipe 3.

[0033] The dimensions of the fixing plate 6 are matched with the dimensions of the groove 5. The left end of the threaded rod 7 passes through the fixing plate 6 and is threadedly connected to the inner wall of the valve body 1. By disassembling the threaded rod 7, the fixing of the fixing plate 6 is removed, and the fixing plate 6 is disassembled, which facilitates the subsequent maintenance or replacement of the valve core 8 and improves the convenience of subsequent maintenance.

[0034] The surface of the valve stem 9 is rotatably connected to the inner wall of the fixed plate 6. The right end of the valve stem 9 passes through the fixed plate 6 and is rotatably connected to the fixed bracket 15. By rotating the handwheel 14, the handwheel 14 drives the extension rod 13 to rotate, causing the worm gear 11 to rotate, which in turn drives the worm wheel 10 to rotate, causing the valve stem 9 to rotate, which in turn drives the valve core 8 to rotate on the inner wall of the valve body 1. Since the valve core 8 is spherical, the water flow channel 2 is closed, making the operation simple and quick.

[0035] The left end of the fixing bracket 15 is fixedly connected to the right end of the fixing plate 6.

[0036] One end of the mounting bracket 12 is fixedly connected to the inner wall of the fixing bracket 15.

[0037] The implementation principle of the valve side-operated structure in this embodiment is as follows: During use, the inlet pipe 3 and outlet pipe 4 are connected to an external fluid pipeline via a flange. Fluid enters the water flow channel 2 inside the valve body 1 through the inlet pipe 3. Since the water flow channel 2 is U-shaped, the fluid flows out through the outlet pipe 4 after passing through the water flow channel 2. By installing the inlet pipe 3 and outlet pipe 4 on one side of the valve body 1, both the inlet and outlet are on one side, making the overall structure more compact and saving installation space. This makes it suitable for space-constrained applications. The design of the U-shaped water flow channel 2 further enhances this effect. This design minimizes resistance to fluid flow and improves fluid flow efficiency. When valve core 8 is closed, rotating handwheel 14 causes extension rod 13 to rotate, which in turn rotates worm gear 11, which in turn rotates worm wheel 10, causing valve stem 9 to rotate. This causes valve core 8 to rotate on the inner wall of valve body 1. Since valve core 8 is spherical, the water flow channel 2 is closed, making operation simple and quick. By disassembling threaded rod 7, the fixing plate 6 can be removed, facilitating subsequent maintenance or replacement of valve core 8 and improving the convenience of subsequent maintenance.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
