Description

Technical Field

[0001] This application relates to the field of sealing rings, and more particularly to a sealing ring with a mesh panel. Background Technology

[0002] A sealing ring is a component installed inside a pipe to improve the sealing performance of pipe connections. The sealing ring is snapped into the pipe, and there are connectors at the ends of the two pipes. When the connectors are connected, they compress the sealing ring, causing it to deform and seal the gaps between the connectors, thus improving the sealing performance of the pipe connection.

[0003] The existing sealing ring has a cylindrical structure. The sealing ring is snapped into the pipe, and the two end faces of the sealing ring abut against the pipe connectors respectively. When the pipe connectors are connected to each other, the pipe connectors squeeze the sealing ring, causing the sealing ring to deform and fit against the inner wall of the pipe connector, thereby reducing the chance of fluid leakage from between the pipe connectors.

[0004] The aforementioned technical solutions have the following drawbacks: In order to filter solid impurities in the fluid inside the pipeline, a filter mechanism needs to be installed between the pipeline connectors. The filter mechanism is large in size and occupies a lot of space. Utility Model Content

[0005] To reduce the space occupied by the filter installation mechanism, this application provides a sealing ring with a mesh.

[0006] The technical solution provided in this application for a sealing ring with a mesh panel is as follows:

[0007] A sealing ring with a mesh includes a ring body and a filter screen. The ring body is a cylindrical structure made of elastic rubber material. The filter screen is a circular plate structure with multiple filter holes. The filter screen is detachably connected to the ring body and is perpendicular to the length direction of the ring body.

[0008] By adopting the above technical solution, a filter screen is set in the ring body, allowing the ring body to be inserted into the pipe, thereby achieving the effect of sealing the pipe connection and improving the pipe's airtightness. When the fluid flows in the pipe, it passes through the filter screen, which can filter out solid impurities in the fluid. The sealing ring is easy to install, has a simple structure, and is convenient to use.

[0009] Optionally, an installation groove is provided on the inner wall of the ring, the installation groove is an annular groove, and the filter screen is snapped into the installation groove.

[0010] By adopting the above technical solution, the filter screen can be inserted into the mounting groove on the inner wall of the ring, making it convenient and quick to install the filter screen in the ring. Users can replace the filter screen with different filter hole sizes, making it convenient to use.

[0011] Optionally, the filter screen has a folded edge, which is inserted into the mounting groove.

[0012] By adopting the above technical solution, and by setting a folded edge on the edge of the filter screen, which is formed by bending the filter screen, the structural strength is better. When fluid passes through the filter screen, the probability of the filter screen edge deformation can be reduced, so that the folded edge can be stably locked in the ring body, reducing the probability of the filter screen falling out of the ring body.

[0013] Optionally, the ring body is provided with multiple external clamps, which are equidistantly spaced along the circumference of the ring body.

[0014] By adopting the above technical solution, and by setting an external clamp outside the ring body, when the ring body is inserted into the pipe, the external clamp abuts against the inner wall of the pipe, thereby improving the stability of the connection between the ring body and the pipe and reducing the probability of the ring body falling out of the pipe.

[0015] Optionally, a water-sealing ring is provided on the end face of the ring body. The water-sealing ring has an annular structure and is coaxially fixed on the ring body.

[0016] By adopting the above technical solution, and by setting a water-sealing ring on the end face of the ring body, the water-sealing ring protrudes and deforms and fits against the surface of the pipe connector when the end face of the ring body abuts against the pipe connector. This reduces the probability of fluid leakage between the end face of the water-sealing ring and the pipe connector, and improves the sealing performance of the sealing ring.

[0017] Optionally, the inner wall of the ring is provided with an inclined protrusion, which is a frustum-shaped structure. The bottom of the inclined protrusion is connected to the ring body, and a through hole is provided at the center of the inclined protrusion.

[0018] By adopting the above technical solution, by setting an inclined protrusion on the inner wall of the ring, when the fluid flows in the pipe, the fluid applies pressure to the side wall of the inclined protrusion. When the fluid pressure is large, the inclined protrusion automatically deforms. The height of the deformed inclined protrusion decreases, and the inner diameter of the through hole in the middle of the inclined protrusion decreases, thereby changing the flow rate of the fluid flowing from the ring and achieving the effect of automatic flow stabilization.

[0019] Optionally, the filter screen has a central groove in the middle, a collection cylinder is connected to the filter screen, the collection cylinder is covered outside the central groove, and the end of the collection cylinder is connected to the filter screen.

[0020] By adopting the above technical solution, a central groove is opened in the middle of the filter screen, and a collection cylinder is connected to the central groove, so that solid impurities on one side of the filter screen can accumulate in the collection cylinder, thereby facilitating the collection and cleaning of solid impurities by users.

[0021] Optionally, the collecting cylinder is configured as a frustum structure, with the inner wall of the collecting cylinder inclined.

[0022] By adopting the above technical solution, and by setting the collection cylinder as a structure with an inclined inner wall, such as a frustum or cone, solid impurities on one side of the filter screen can slide along the inclined inner wall of the collection cylinder to the bottom of the collection cylinder, thereby allowing the impurities on one side of the filter screen to accumulate in the collection cylinder, making it convenient for users to collect and clean the impurities.

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

[0024] 1. By setting a filter screen in the ring body, the ring body can be inserted into the pipe, thereby sealing the pipe connection and improving the pipe's airtightness. When the fluid flows in the pipe, it passes through the filter screen, which can filter out solid impurities in the fluid. The sealing ring is easy to install, has a simple structure, and is convenient to use.

[0025] 2. By setting a folded edge at the edge of the filter screen, which is formed by bending the filter screen, the structural strength is better. When fluid passes through the filter screen, it can reduce the chance of the filter screen edge deformation, so that the folded edge can be stably locked in the ring, reducing the chance of the filter screen falling out of the ring.

[0026] 3. By setting a water-sealing ring on the end face of the ring body, the water-sealing ring protrudes and deforms and fits against the surface of the pipe connector when the end face of the ring body abuts against the pipe connector. This reduces the chance of fluid leakage between the end face of the water-sealing ring and the pipe connector, and improves the sealing performance of the sealing ring. Attached Figure Description

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] This application discloses a sealing ring with a mesh panel, as shown in the embodiments below. Figure 1 , Figure 2 and Figure 3 The system includes a ring body 1 and a filter screen 2. The ring body 1 is made of elastic rubber and has a cylindrical structure. The filter screen 2 has a circular plate structure with multiple filter holes and is detachably connected to the ring body 1. The ring body 1 is used to snap and fix the system inside the pipe. When the fluid flows in the pipe, it passes through the filter screen 2, allowing solid impurities in the fluid to be filtered out. The filtered solid impurities are trapped on one side of the filter screen 2. Users can install sealing rings at the pipe connections, which can effectively seal the gaps between the pipes and filter impurities in the fluid, simplifying the pipe structure and reducing maintenance costs.

[0037] Reference Figure 2 The ring body 1 is provided with multiple outer clamps 11, which are fixed at equal intervals along the circumference of the ring body 1 on the outer wall of the ring body 1. The outer clamps 11 are integrally formed and connected to the ring body 1. When the ring body 1 is locked in the pipe, the outer clamps 11 abut against the inner wall of the pipe, thereby improving the stability of the ring body 1 in the pipe.

[0038] Reference Figure 2 A water-sealing ring 12 is provided on the ring body 1, and the water-sealing ring 12 is located on the end face of the ring body 1. The water-sealing ring 12 has a circular structure and is coaxially arranged with the ring body 1. The water-sealing ring 12 is integrally set with the ring body 1. When the sealing ring is stuck in the pipe, the end face of the ring body 1 abuts against the connector at the pipe connection, and the water-sealing ring 12 abuts against and deforms against the pipe connector, making it difficult for fluid to leak from the end face of the ring body 1 and the connector, further improving the sealing performance of the pipe connection.

[0039] Reference Figure 2 and Figure 3 The ring body 1 is provided with an inclined protrusion 13, which is a frustum-shaped structure. The inclined protrusion 13 is coaxially arranged with the ring body 1 and is angled relative to the inner wall of the ring body 1. A through hole is opened at the center of the inclined protrusion 13. When fluid passes through the middle of the ring body 1, the fluid exerts pressure on the inclined protrusion 13. When the fluid pressure is high, the inclined protrusion 13 deforms. When the inclined protrusion 13 is under pressure, its height decreases. At this time, the size of the through hole in the middle of the inclined protrusion 13 decreases, causing the flow rate of the fluid passing through the inclined protrusion 13 to change, thereby controlling the flow rate change in the pipeline.

[0040] Reference Figure 3 An installation groove 14 is provided on the inner wall of the ring body 1. The edge of the filter screen 2 is engaged in the installation groove 14. When the filter screen 2 is installed in the installation groove 14, the filter screen 2 is perpendicular to the side wall of the ring body 1. Users can replace the filter screen 2, so that filter screens 2 with different filter hole sizes can be easily and quickly installed in the ring body 1, improving the flexibility of use.

[0041] Reference Figure 4 The edge of the filter screen 2 is bent to form a folded edge 21. After bending, the folded edge 21 is perpendicular to the filter screen 2. The structure of the folded edge 21 is stable. When the folded edge 21 is stuck in the mounting groove 14, the folded edge 21 is not easily deformed, thereby reducing the probability of the filter screen 2 detaching from the ring body 1. The folded edge 21 being stuck in the mounting groove 14 can reduce the probability of the filter screen 2 shaking in the ring body 1.

[0042] Reference Figure 5 and Figure 6 In other embodiments, a central groove 22 is provided in the middle of the filter screen 2, and a collection cylinder 23 is provided at the center of the filter screen 2. The collection cylinder 23 is a cylindrical structure with a bottom and is coaxially fixed to the filter screen 2. The collection cylinder 23 is used to collect solid impurities in the fluid. When the fluid passes through the filter screen 2, the solid impurities in the fluid can accumulate in the collection cylinder 23, which makes it convenient for the user to clean the impurities on the filter screen 2.

[0043] Reference Figure 7 In other embodiments, the collecting cylinder 23 is configured as a frustum-shaped structure with inclined sidewalls inside. The cross-sectional area of ​​the side of the collecting cylinder 23 connected to the filter screen 2 is larger, while the cross-sectional area of ​​the bottom side of the collecting cylinder 23 is smaller. When the filter screen 2 filters out solid impurities in the fluid, the solid impurities can slide along the inner sidewall of the filter screen 2, thereby making it easier for the solid impurities to accumulate inside the collecting cylinder 23, which facilitates cleaning of the filter screen 2.

[0044] The implementation principle of this application embodiment is as follows: by setting a filter screen 2 on the ring body 1, when the ring body 1 is stuck in the pipe, the fluid in the pipe flows through the filter screen 2, and the filter screen 2 plays the role of filtering solid impurities in the fluid. By opening an installation groove 14 on the ring body 1, the filter screen 2 can be stuck in the installation groove 14, thereby making it convenient for users to install filter screens 2 with different filter hole sizes on the ring body 1, which is convenient for use.

[0045] 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.
