Description

Technical Field

[0001] This application relates to the field of water pipe components, and in particular to a flow-limiting sealing ring. Background Technology

[0002] Water pipe networks are widely used water distribution systems in both civil and industrial sectors. By connecting multiple pipes together, water can flow in a directional manner within the pipes, and they are widely used in heating, water supply, and other fields.

[0003] Multiple devices are installed in the water pipe network to stabilize the water flow, enabling the network terminals to receive a constant flow of water over a long period. When the water pressure at the supply end changes, the water flow rate in the network increases, leading to an increase in the flow rate at the terminals. The flow stabilizing devices then reduce the inner diameter of the pipes to maintain a stable flow rate at the terminals. When the water pressure at the supply end returns to a lower level, the flow stabilizing devices activate again to increase the inner diameter of the pipes.

[0004] The aforementioned technical solutions have the following drawbacks: existing flow stabilization devices are usually set as valve bodies, which are large in size, complex to install, and inconvenient to use in the civilian field. Utility Model Content

[0005] To simplify the structure of water pipes with flow stabilization function, this application provides a flow-limiting sealing ring.

[0006] The flow-limiting sealing ring provided in this application adopts the following technical solution:

[0007] A flow-limiting sealing ring includes a sealing ring body and a rubber cone. The sealing ring body includes a cylindrical body and a bottom. The cylindrical body has a cylindrical structure, and the bottom is located at one end of the cylindrical body. The rubber cone is located at the bottom and inside the cylindrical body. The rubber cone has a conical structure, and the bottom surface of the rubber cone is connected to the bottom. The sealing ring body has multiple connecting holes I, and the rubber cone has multiple connecting holes II. The positions and diameters of the connecting holes I and II correspond one-to-one.

[0008] By adopting the above technical solution, a rubber cone is set on the sealing ring body, and a connecting hole one is opened on the sealing ring body and a connecting hole two is opened on the rubber cone. When the water flows unidirectionally in the pipe, the water flow impacts the rubber cone, thereby flattening the rubber cone and reducing the diameter of the connecting hole two on the rubber cone. At this time, the flow rate of water flowing through the connecting hole two is small. Under the combined effect of increased water pressure and reduced pipe inner diameter, the flow rate of water flowing through the pipe remains stable with small changes. When the water pressure at the water supply end fluctuates, the rubber cone can automatically undergo elastic deformation and control the flow rate change. The sealing ring body can be installed at the connection of two pipes, and the structure is simplified.

[0009] Optionally, the cylinder and the rubber cone are coaxially arranged.

[0010] By adopting the above technical solution, and by connecting the cylinder and the rubber cone coaxially, when water flows in the inlet pipe, the water flow applies a uniform impact to the side wall of the rubber cone, thereby causing the multiple connecting holes on the rubber cone to undergo uniform deformation, making the deformation of each connecting hole approximately the same.

[0011] Optionally, the end of the cylinder away from the bottom is provided with an outwardly convex circle.

[0012] By adopting the above technical solution, by setting an outer convex circle on the cylinder, when the water inlet pipe and the water outlet pipe are connected through a threaded pipe, the sealing ring body can be set inside the threaded pipe. The two threaded pipes of the two pipes together squeeze the outer convex circle, causing the outer convex circle to deform and fill the threaded pipe.

[0013] Optionally, the sealing ring body and the rubber cone are detachably connected.

[0014] By adopting the above technical solution, and by detachably connecting rubber cones to the sealing ring body, users can install rubber cones with different elasticities on the sealing ring body, thereby making the rubber cones have different resistance to deformation and different degrees of deformation of the connecting hole two when subjected to water flow pressure, thus playing a different role in stabilizing the flow.

[0015] Optionally, a threaded hole is provided at the center of the bottom circle, and a stud is coaxially provided at the bottom of the rubber cone, with the stud threadedly connected to the threaded hole.

[0016] By adopting the above technical solution, and by setting a stud on the rubber cone, the stud can be inserted into the threaded hole and threadedly connected to the sealing ring body, so that the rubber cone can be conveniently and quickly installed on the sealing ring body.

[0017] Optionally, the threaded hole is a through hole.

[0018] By adopting the above technical solution, the threaded hole is opened as a through hole, allowing the stud to extend out from the through hole, which makes it convenient for the user to screw the stud and make the bottom of the rubber cone abut against the bottom of the sealing ring body.

[0019] Optionally, a pin is provided on the bottom surface of the rubber cone, the pin is perpendicular to the bottom surface of the rubber cone, and an insertion hole is provided on the bottom, the pin is used to insert into the insertion hole.

[0020] By adopting the above technical solution, a pin is set on the rubber cone so that the pin can be inserted into the insertion hole, thereby allowing the rubber cone to be locked inside the sealing ring body.

[0021] Optionally, multiple pins are provided, and multiple sockets are provided, with each pin corresponding to a specific socket.

[0022] By adopting the above technical solution, multiple pins are set on the rubber cone to achieve a positioning effect. When the rubber cone is impacted by water flow, the probability of the rubber cone sliding and rotating within the sealing ring body is reduced, thereby ensuring that the first connecting hole and the second connecting hole always maintain their corresponding positions.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By setting a rubber cone on the sealing ring body, and opening a connecting hole one on the sealing ring body and a connecting hole two on the rubber cone, when the water flows unidirectionally in the pipe, the water flow impacts the rubber cone, thereby flattening the rubber cone and reducing the diameter of the connecting hole two on the rubber cone. At this time, the flow rate of the water flowing through the connecting hole two is small. Under the combined effect of increased water pressure and reduced pipe inner diameter, the flow rate of the water flowing through the pipe remains stable with small changes. When the water pressure at the water supply end fluctuates, the rubber cone can automatically undergo elastic deformation and control the flow rate change. The sealing ring body can be installed at the connection of two pipes, and the structure is simplified.

[0025] 2. By setting an outer convex circle on the cylinder, when the inlet pipe and outlet pipe are connected through a threaded pipe, the sealing ring body can be set inside the threaded pipe. The two threaded pipes of the two pipes together squeeze the outer convex circle, causing the outer convex circle to deform and fill the threaded pipe.

[0026] 3. By detachably connecting rubber cones to the sealing ring body, users can install rubber cones with different elasticities on the sealing ring body, thereby making the rubber cones have different resistance to deformation and different degrees of deformation of the connecting hole two when subjected to water flow pressure, thus playing a different role in stabilizing the flow.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a flow-limiting sealing ring, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a sealing ring body 1 and a rubber cone 2. The sealing ring body 1 includes a cylindrical body 11 and a bottom 12. The cylindrical body 11 has a cylindrical structure, and the bottom 12 connects to and seals an opening on one side of the cylindrical body 11. The cylindrical body 11 and the bottom 12 are integrally formed by a mold. The bottom 12 has multiple connecting holes 14, which are equidistantly spaced along the circumference of the cylindrical body 11 and penetrate the bottom 12. The rubber cone 2 is fixed to the bottom 12 and located inside the cylindrical body 11. The rubber cone 2 has a conical structure and is coaxially arranged with the bottom 12. The rubber cone 2 has multiple connecting holes 21, the position and size of which correspond one-to-one with the connecting holes 14. Each connecting hole 14 communicates with one connecting hole 21. The sealing ring body 1 and the rubber cone 2 are arranged between the inlet pipe 3 and the outlet pipe 4. The rubber cone 2 is arranged on the side facing the inlet pipe 3. When there is water in the inlet pipe 3, the water flows from the inlet pipe 3 into the outlet pipe 4. The water can pass through the sealing ring body 1 through the connecting hole 14 and the connecting hole 21. When the water pressure is large, the water applies pressure to the rubber cone 2, causing the rubber cone 2 to undergo elastic deformation. At this time, the diameter of the connecting hole 21 in the rubber cone 2 becomes smaller. When the water pressure in the inlet pipe 3 changes, the water flow rate of the outlet pipe 4 can be kept constant.

[0035] Reference Figure 2 The sealing ring body 1 has a convex circle 13, which is located on the end face of the cylinder 11 away from the bottom 12. The convex circle 13 is a ring structure and is perpendicular to the cylinder 11. The inner diameter of the cylinder 11 and the convex circle 13 are the same. The inlet pipe 3 has a threaded pipe 31 at its end, and the outlet pipe 4 has a threaded pipe 41 at its end. The threaded pipe 31 and the threaded pipe 41 are threaded together. When the threaded pipe 31 and the threaded pipe 41 are connected, they abut against the upper and lower end faces of the convex circle 13, respectively. The convex circle 13 can deform and seal the gap between the threaded pipe 31 and the threaded pipe 41, improving the sealing performance of the connection between the threaded pipe 31 and the threaded pipe 41.

[0036] Reference Figure 4 In other embodiments, the sealing ring body 1 and the rubber cone 2 are detachably connected. By installing rubber cones 2 of different materials on the sealing ring body 1 and adjusting the height of the rubber cones 2, users can install rubber cones 2 of different elasticities on the sealing ring body 1, thereby causing the rubber cones 2 to deform to different degrees under stress, which facilitates the production of sealing ring bodies 1 with different performance characteristics.

[0037] Reference Figure 4 A stud 22 is provided at the center of the bottom surface of the rubber cone 2. The stud 22 is coaxially connected to the rubber cone 2 and is integrally formed with the rubber cone 2. A threaded hole 121 is opened at the center of the bottom 12, and the stud 22 is used to connect coaxially with the threaded hole 121. The threaded hole 121 can be a blind hole or a through hole. When the threaded hole 121 is a through hole, the stud 22 protrudes from the through hole, making it convenient for users to tighten and replace the rubber cone 2.

[0038] Reference Figure 5 In other embodiments, a pin 23 is provided on the rubber cone 2. The pin 23 has a cylindrical structure and is fixed to the bottom of the rubber cone 2 and perpendicular to the bottom surface of the rubber cone 2. Multiple insertion holes 122 are provided on the bottom 12. The pin 23 is used to insert into the insertion holes 122, and the pin 23 is interference-fitted with the insertion holes 122. By engaging the rubber cone 2 and the sealing ring body 1, the pin 23 achieves a positioning effect. When the sealing ring body 1 and the rubber cone 2 are connected, the connecting hole 14 and the connecting hole 21 correspond one-to-one, reducing the steps required for users to adjust the position of the rubber cone 2. When the rubber cone 2 is subjected to stress, the probability of the rubber cone 2 sliding on the bottom 12 can be reduced.

[0039] The implementation principle of this application embodiment is as follows: By setting a rubber cone 2 on the sealing ring body 1, the sealing ring body 1 is positioned between the water inlet pipe 3 and the water outlet pipe 4. When water flows through the sealing ring body 1, the water flows in and out from the side on which the rubber cone 2 is set on the sealing ring body 1. The water flow impacts the rubber cone 2, causing the rubber cone 2 to deform, thereby reducing the diameter of the second connecting hole 21 in the rubber cone 2. This allows the rubber cone 2 to automatically deform when the water pressure is high, thereby maintaining a constant water flow. When the water pressure decreases, the rubber cone 2 automatically rebounds, increasing the diameter of the second connecting hole 21, which is convenient to use.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
