Description

Technical Field

[0001] The utility model relates to the technical field of sealing elements, in particular to an integrated locking device of an annular silicon carbide sealing element. Background Art

[0002] Silicon carbide seals are widely used in industry due to their high hardness, excellent heat resistance, and corrosion resistance. This material can remain stable at temperatures up to 1600°C and exhibits excellent resistance to most acidic and alkaline solutions, making it suitable for use in harsh environments. Silicon carbide seals are commonly used in pumps and valves in the chemical industry, high-temperature and high-pressure equipment in the energy industry, key components in automotive engines, and in the extreme conditions of the aerospace industry, providing reliable sealing solutions.

[0003] In traditional mechanical seal designs, silicon carbide seals are often connected to the stationary ring seat using bolts and nuts. This method secures the seal to the stationary ring seat, ensuring stability and sealing performance during operation. However, bolted connections require tools such as wrenches to tighten and loosen, making installation and removal time-consuming and inconvenient, especially in confined or difficult-to-access locations. Utility Model Content

[0004] The purpose of the utility model is to provide an integrated locking device for an annular silicon carbide seal, so as to solve the problem that the installation of the silicon carbide seal in the prior art is too troublesome.

[0005] To achieve the above-mentioned purpose, an integrated locking device for a circular silicon carbide seal is provided, comprising a stationary ring seat, an outer shell and a sealing ring. A plurality of groups of holes connecting the inner and outer sides are provided in the middle of the stationary ring seat. An inner clamping ball is provided at the inner hole of the stationary ring seat, and an outer clamping ball is provided at the outer hole of the stationary ring seat. The inner clamping ball is elastically connected to the outer clamping ball through a clamping ball spring.

[0006] As a further improvement of the technical solution, sliding grooves are provided between the outer holes of the static ring seat, and the housing is provided with multiple groups of sliding blocks and fixedly connected thereto, and the sliding blocks are movably engaged with the sliding grooves.

[0007] As a further improvement of the present technical solution, a groove for accommodating a spring is provided below the sliding groove, and the spring is elastically connected to the sliding block.

[0008] As a further improvement of the present technical solution, ball grooves are provided between the sliding blocks, and when the housing slides downward, the outer clamping balls can fall into the ball grooves.

[0009] As a further improvement of the technical solution, a spherical groove is provided on the outer side of the sealing ring, and the sealing ring is fixedly connected with the spherical groove and the inner clamping ball.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In the integrated locking device of the annular silicon carbide seal, the outer shell is lifted by the sliding spring to make the outer snap-on ball leave the ball groove, and then the snap-on ball spring is compressed to drive the inner snap-on ball into the spherical groove, so that the sealing ring can be easily installed and fixed. Similarly, the outer shell is slid downward to make the outer snap-on ball enter the ball groove, and then the snap-on ball spring is loosened to drive the inner snap-on ball out of the spherical groove. At this time, the sealing ring can be easily removed, realizing installation and removal without tools, greatly simplifying the operation process, and is particularly suitable for working environments with limited space.

[0012] 2. The integrated locking device of the annular silicon carbide seal features a spherical groove and inner snap-in ball design that provides a natural positioning function, ensuring that the sealing ring automatically aligns during installation, thereby adjusting to the optimal sealing position. This ensures a good sealing effect and reduces misalignment problems caused by human factors. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0022] See also Figure 1-Figure 4 As shown, the purpose of this embodiment is to provide an integrated locking device for an annular silicon carbide seal, comprising three major parts: a stationary ring seat 1, an outer shell 2 and a sealing ring 3. A plurality of groups of holes are designed in the middle of the stationary ring seat 1 that pass through the inner and outer sides thereof. These holes serve to place the inner snap-in ball 14, the outer snap-in ball 12 and the snap-in ball spring 15. An inner snap-in ball 14 is provided at the inner hole of the stationary ring seat 1, and an outer snap-in ball 12 is provided at the outer hole. The inner snap-in ball 14 forms an elastic connection with the outer snap-in ball 12 through the snap-in ball spring 15, so that the device can be conveniently operated by compressing and releasing the spring during installation and disassembly.

[0023] Sliding grooves 13 are designed between the outer holes of the stationary ring seat 1, allowing multiple sets of sliding blocks 22 on the housing 2 to engage with them. Ball bearing grooves 21 are located between the sliding blocks 22 of the housing 2. When the housing 2 slides downward, the outer engaging balls 12 fall into the grooves 21, thereby unlocking the device. Furthermore, a sliding spring 11 is installed in a groove below the sliding grooves 13. The elastic connection between the sliding spring 11 and the sliding blocks 22 enhances the device's flexibility and reliability.

[0024] The outer surface of the sealing ring 3 is provided with a spherical groove 31. This design allows the sealing ring 3 to securely engage with the inner engaging ball 14 on the stationary ring seat 1. The combination of the spherical groove 31 and the inner engaging ball 14 not only provides a natural positioning function but also ensures that the sealing ring 3 automatically aligns during installation, achieving the optimal sealing position. This avoids alignment issues caused by human factors and ensures a good sealing effect.

[0025] In actual use, when the sealing ring 3 needs to be installed, the outer shell 2 can be lifted up by the sliding spring 11, so that the outer snap-in ball 12 is disengaged from the ball groove 21, thereby compressing the snap-in ball spring 15 and allowing the inner snap-in ball 14 to smoothly squeeze into the ball groove 31 of the sealing ring 3, achieving quick installation. Conversely, to remove the sealing ring 3, the outer shell 2 can be moved downward to allow the outer snap-in ball 12 to re-enter the ball groove 21. At this time, the snap-in ball spring 15 is relaxed, and the inner snap-in ball 14 will exit the ball groove 31, making it easy to remove the sealing ring 3.

[0026] Working principle:

[0027] The outer shell 2 is lifted by the sliding spring 11 so that the outer clamping ball 12 leaves the ball groove 21, and then the clamping ball spring 15 is compressed to drive the inner clamping ball 14 to squeeze into the spherical groove 31 of the sealing ring 3, thereby fixing the sealing ring 3; on the contrary, when disassembly is required, the outer shell 2 is slid downward to make the outer clamping ball 12 enter the ball groove 21, and then the clamping ball spring 15 is loosened to drive the inner clamping ball 14 to leave the spherical groove 31, and the sealing ring 3 can be easily removed.

[0028] This design allows for tool-free installation and removal, simplifying the process and making it particularly suitable for work environments with limited space. Furthermore, the spherical groove 31 and the inner snap-in ball 14 provide a natural positioning function, ensuring that the sealing ring 3 automatically aligns during installation, adjusting to the optimal sealing position and ensuring a good sealing effect.

[0029] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
