Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a bracket-integrated double-ruler ball valve. Background Technology

[0002] A ball valve with a nut is a type of ball valve. Its main feature is that it uses a nut as a connecting component. A nut is a device that facilitates pipe connection and consists of a nut, a short pipe, and a sealing gasket. The ball is the core component of the ball valve with a circular channel. The ball is made of metal and its surface is finely machined to ensure good sealing and smooth rotation.

[0003] The dual-ruler ball valve is composed of two union connectors. When opened, the operator holds the operating handle and rotates the ball until the channel on the ball aligns with the pipeline axis. At this time, fluid enters the ball valve from the pipeline, passes through the ball channel, and then flows out from the outlet, with the valve fully open. During this process, the flow resistance of the fluid inside the ball valve is small because the diameter of the ball channel is similar to the inner diameter of the pipeline, ensuring smooth fluid flow. However, current dual-ruler ball valves have the problem of excessive operating torque. On the one hand, when the valve is not used for a long time or in harsh environments, such as when rust or scale builds up, a large frictional force will be generated between the ball and the valve seat, making it difficult to rotate the operating handle. The existing solution is to use coating technology to coat the surface of the ball with a low-friction coefficient coating, such as a molybdenum disulfide coating. This coating effectively reduces the frictional force between the ball and the valve seat and reduces the operating torque. However, when multiple pipelines are connected, the lack of a fixed connecting structure between the ball valves still requires an additional support frame for connection, thus reducing space utilization and making it inconvenient to integrate and arrange the pipelines, thereby reducing the practicality of the ball valve. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bracket-integrated double-ruler ball valve, which aims to improve the problem that the existing technology requires an additional support frame for connection, thereby reducing space utilization and making it inconvenient to integrate and arrange pipelines.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bracket-integrated double-rudder ball valve, comprising a valve body, a handle rotatably connected to the top of the valve body, a connecting block fixedly connected to the front side of the valve body, a locking groove formed on the front side of the connecting block, rotating shells rotatably connected to the upper and lower sides of the outer wall of the connecting block, locking plates rotatably connected to the left and right sides of the top rotating shell, and locking grooves formed on the left and right sides of the bottom rotating shell, the bottom of the locking plate engaging with the locking groove, a fixing post fixedly connected to the rear side of the valve body, a locking post fixedly connected to the rear side of the fixing post, the rear side of the locking post engaging with the locking groove, and locking mechanisms provided on both the front and rear sides of the handle, the locking mechanisms being used to improve the limiting effect of the handle, thereby improving the safety of the valve body.

[0006] As a further description of the above technical solution:

[0007] The locking mechanism includes two limiting shells, with adjacent sides of the two limiting shells fixedly connected to the front and rear sides of the handle, respectively. A threaded rod is rotatably connected to the inner bottom wall of the limiting shell, and a knob is fixedly connected to the top end of the threaded rod. A displacement plate is threadedly connected to the outer wall of the threaded rod, and one side of the displacement plate is slidably connected to the inner wall of the limiting shell. A locking pin is fixedly connected to the bottom of the displacement plate, and baffles are fixedly connected to both the left and right sides of the displacement plate. Limiting plates are fixedly connected to both the front and rear sides of the handle. Locking holes are provided on both the front and rear sides of the top of the valve body. The bottom end of the locking pin passes through the middle of the limiting plate and engages with the locking hole.

[0008] As a further description of the above technical solution:

[0009] The locking mechanism also includes two protective shells, the bottoms of which are fixedly connected to the tops of the corresponding limiting shells.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the knob is fixedly connected with multiple rubber strips, all of which are arranged in an equidistant ring.

[0012] As a further description of the above technical solution:

[0013] Positioning plates are fixedly connected to the left and right sides of the inner walls of the two rotating shells. Multiple positioning grooves are opened on the left and right sides of the fixed column. One side of each of the multiple positioning plates is slidably connected to the corresponding positioning groove.

[0014] As a further description of the above technical solution:

[0015] The top rotating shell has connecting columns fixedly connected to the left and right sides of its bottom wall, and the bottom rotating shell has connecting grooves on the left and right sides of its top wall, with the bottom of the connecting columns engaging with the connecting grooves.

[0016] As a further description of the above technical solution:

[0017] Rubber pads are fixedly connected to adjacent sides of the two rotating shells, and arc surfaces are formed on adjacent sides of the two rubber pads.

[0018] As a further description of the above technical solution:

[0019] Multiple rubber posts are fixedly connected to both the front and rear sides of the handle, and the multiple rubber posts are all designed symmetrically.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by rotating the locking plate, its bottom end is separated from the corresponding locking groove, thereby unlocking the two rotating shells. Then, the rotating shells are flipped over to open them. Subsequently, by pulling the fixing column, the locking column is separated from the locking groove on one side of the connecting block, thereby achieving the purpose of disassembly. Conversely, the installation of the two valve bodies is completed, which avoids the need for an additional support frame to support the pipeline, thereby improving the space utilization rate.

[0022] 2. In this utility model, the rotation of the knob causes the threaded rod to rotate, thus giving the displacement plate a tendency to rotate and move. Under the restriction of the displacement plate by the limiting shell, it will not rotate, thereby completing the lifting and lowering, separating the locking pin from the locking hole in the valve body, achieving the purpose of releasing the limit, and vice versa, completing the limit. This avoids the situation where the handle is accidentally opened or closed due to collision. At the same time, the connection of the baffle plate protects the connection between the handle and the valve body, improving its service life. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a bracket-integrated double-rudder ball valve, including a valve body 1. A handle 3 is rotatably connected to the top of the valve body 1, and a connecting block 4 is fixedly connected to the front side of the valve body 1. The connecting block 4 completes the rotational connection of two rotating shells 5 and simultaneously completes the initial fixation of the locking column 10. A locking groove 8 is opened on the front side of the connecting block 4. Rotating shells 5 are rotatably connected to the upper and lower sides of the outer wall of the connecting block 4. Locking plates 6 are rotatably connected to the left and right sides of the top rotating shell 5, and the left side of the bottom rotating shell 5 is... Locking slots 7 are provided on the right side. When the locking plate 6 is flipped, it separates or engages with the corresponding locking slot 7 to lock or unlock the rotating shell 5. The bottom of the locking plate 6 engages with the locking slot 7. A fixing post 9 is fixedly connected to the rear side of the valve body 1. A locking post 10 is fixedly connected to the rear side of the fixing post 9. The rear side of the locking post 10 engages with the locking slot 8. Locking mechanisms 2 are provided on both the front and rear sides of the handle 3. The locking mechanism 2 is used to improve the limiting effect of the handle 3, thereby improving the safety of the valve body 1.

[0032] Specifically, ensuring the locking plate 6 can rotate completely allows its bottom end to separate from the corresponding locking groove 7. As the locking plate 6 rotates, the two rotating shells 5 are unlocked, allowing them to be opened. With the rotating shells 5 open, one side of the connecting block 4 is exposed. By pulling the fixing column 9, the locking column 10 can be separated from the locking groove 8 on one side of the connecting block 4, allowing the other valve body 1 to be easily disassembled. Conversely, the installation of the two valve bodies 1 can be completed through the same steps. In this way, the need for additional support frames to support the pipes is avoided, thereby not only improving space utilization but also ensuring the orderly arrangement of water pipes, making the layout of the entire system more compact and efficient.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The locking mechanism 2 includes two limiting shells 201. The adjacent sides of the two limiting shells 201 are fixedly connected to the front and rear sides of the handle 3, respectively. A threaded rod 202 is rotatably connected to the inner bottom wall of the limiting shell 201. A knob 203 is fixedly connected to the top end of the threaded rod 202. Rotation of the knob 203 causes the threaded rod 202 to rotate synchronously. A displacement plate 205 is threadedly connected to the outer wall of the threaded rod 202. One side of the displacement plate 205 is slidably connected to the inner wall of the limiting shell 201. A locking pin 206 is fixedly connected to the bottom of the displacement plate 205. Thus, by rotating the threaded rod 202, the displacement plate 205 is raised and lowered, thereby driving the locking pin 206 to rise and fall. The left and right sides of the displacement plate 205 are fixedly connected to baffles 207, and the front and rear sides of the handle 3 are fixedly connected to limit plates 208. The top and front and rear sides of the valve body 1 are provided with locking holes 209. By raising and lowering the locking pin 206, it is engaged with the corresponding locking hole 209 to achieve the purpose of limiting or unlocking. The bottom end of the locking pin 206 passes through the middle of the limit plate 208 and engages with the locking hole 209.

[0034] Specifically, by rotating the knob 203, the threaded rod 202 is rotated synchronously, giving the displacement plate 205 both rotational and displacement tendencies. Under the restriction of the limiting shell 201, the rotation of the displacement plate 205 is effectively limited, thus allowing it to move up and down along the direction of the threaded rod 202. This causes the locking pin 206 to separate from the corresponding locking hole 209, thereby achieving the effect of releasing the limit. Conversely, when it is necessary to limit the handle 3, the locking pin 206 can be re-engaged with the locking hole 209 through the corresponding operation, thereby preventing the handle 3 from being accidentally opened or closed due to collision. In addition, the addition of the baffle 207, through its lifting action, further protects the connection between the handle 3 and the valve body 1, effectively improving the service life of the entire device.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The locking mechanism 2 also includes two protective shells 17, the bottoms of which are fixedly connected to the tops of the corresponding limiting shells 201; multiple rubber strips 204 are fixedly connected to the outer wall of the knob 203, and the multiple rubber strips 204 are arranged in an equidistant ring; positioning plates 11 are fixedly connected to the left and right sides of the inner walls of the two rotating shells 5, and multiple positioning grooves 12 are opened on the left and right sides of the fixing column 9, and one side of the multiple positioning plates 11 is slidably connected to the corresponding positioning groove 12.

[0036] Specifically, the protective shell 17 protects the top of the outer wall of the threaded rod 202, the multiple rubber strips 204 bypass the anti-slip effect of the knob 203, and the connection between the positioning plate 11 and the positioning groove 12 completes the positioning and installation of the fixed column 9.

[0037] Reference Figure 1 and Figure 4 The top rotating shell 5 has connecting posts 15 fixedly connected to the left and right sides of its bottom wall, and connecting grooves 16 are opened on the left and right sides of its top wall. The bottom of the connecting posts 15 engages with the connecting grooves 16. Rubber pads 13 are fixedly connected to adjacent sides of the two rotating shells 5, and arc surfaces are opened on adjacent sides of the two rubber pads 13. Multiple rubber posts 14 are fixedly connected to the front and rear sides of the handle 3, and the multiple rubber posts 14 are symmetrically designed.

[0038] Specifically, the engagement of the connecting post 15 with the connecting groove 16 improves the connection effect of the rotating shell 5, the connection of the rubber pad 13 improves the fixing effect of the rotating shell 5 on the fixed post 9, and the fixed connection of multiple rubber posts 14 improves the service life of the handle 3.

[0039] Working principle: When the valve body 1 is disassembled and replaced, the locking plate 6 rotates, thereby separating its bottom end from the corresponding locking groove 7. Then, the two rotating shells 5 are unlocked, exposing one side of the connecting block 4. Then, by pulling the fixing column 9, the locking column 10 is separated from the locking groove 8 on one side of the connecting block 4, thereby achieving the purpose of disassembling the other valve body 1. Conversely, the installation of the two valve bodies 1 is completed, thus avoiding the need for an additional support frame to support the pipeline, thereby improving space utilization and ensuring the orderly arrangement of water pipes.

[0040] Furthermore, by rotating the knob 203, the threaded rod 202 rotates synchronously, causing the displacement plate 205 to have a tendency to rotate and move. Under the restriction of the displacement plate 205 by the limiting shell 201, the displacement plate 205 will not rotate, thereby completing the lifting and lowering along the direction of the threaded rod 202, separating the locking pin 206 from the corresponding locking hole 209, achieving the purpose of releasing the limit. Conversely, it completes the limit of the handle 3, avoiding the situation where the handle 3 is opened or closed due to collision. At the same time, with the connection of the baffle 207, the lifting and lowering of the baffle 207 achieves the protection of the connection between the handle 3 and the valve body 1, improving its service life.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
