Description

Technical Field

[0001] The utility model relates to the technical field of mechanical sealing rings, in particular to a containerized mechanical sealing ring. Background Art

[0002] The Cartridge Mechanical Seal is a highly integrated sealing solution designed for rotating equipment (such as pumps, agitators, compressors, etc.) to prevent fluid leakage and protect the equipment from contamination. Compared with traditional split mechanical seals, the Cartridge Mechanical Seal has the characteristics of pre-assembly, easy installation, simple maintenance and superior sealing performance. Here are some key features and advantages of the Cartridge Mechanical Seal: Key Features: 1. Pre-assembled structure: The Cartridge Mechanical Seal pre-integrates components such as the dynamic ring, static ring, spring, auxiliary seal ring, sleeve, gland and possible cooling or flushing system into a compact unit to form a plug-and-play sealing assembly. 2. Easy to install and replace: Due to its integrated design, the cartridge seal only needs to be installed on the equipment as a whole during installation, which greatly simplifies the installation process, reduces installation errors, and also shortens the time required for maintenance and replacement. 3. Standardization and interchangeability: Many cartridge mechanical seals follow certain standard sizes and interfaces, which improves the interchangeability between different brands or models and facilitates user selection and replacement. 4. Improve sealing performance: The carefully designed sealing surface geometry and materials, as well as the precise preload control, ensure good sealing effect, reduce leakage, and are suitable for handling various media, including corrosive, high temperature, and high-pressure fluids. 5. Built-in adjustment and compensation mechanism: Some container seals are designed with automatic adjustment functions, which can automatically compensate for the sealing surface gap according to changes in operating conditions and maintain long-term stable sealing performance. 6. Reduce maintenance costs: The integrated design reduces the number of components, simplifies maintenance procedures, and reduces the failure rate caused by improper maintenance, thereby reducing overall operating costs. Application areas: Container mechanical seals are widely used in industrial fields such as chemical, petrochemical, pharmaceutical, food processing, papermaking, and water treatment. They are especially suitable for those occasions with strict requirements on sealing performance and require frequent maintenance or rapid replacement of seals. With the continuous advancement of technology, the design and performance of container mechanical seals are also continuously optimized to meet the sealing needs under different working conditions.

[0003] The Chinese invention patent with application number CN108131449B discloses a mechanical seal ring with superhard material surfacing, which includes a dynamic seal ring and a static seal ring. The end face of the static seal ring in contact with the dynamic seal ring is surfacing with superhard carbide material, and the end face of the dynamic seal ring in contact with the static seal ring is surfacing with superhard carbide and is provided with a spiral chip groove with a spiral direction opposite to the rotation direction of the dynamic seal ring. The end of the spiral chip groove is located on the inner wall of the dynamic seal ring. The spiral chip groove is surfacing with low hardness material and is flush with the surface of the end face. The width and depth of the spiral chip groove increase with the spiral direction and the starting and ending ends of the spiral chip groove are located on the same radius of the dynamic seal ring. The first wear position on the working surface of the dynamic seal ring and the static seal ring is at the spiral chip groove, which is enriched with high-hardness metal chips. These metal chips are discharged along the spiral chip groove under the action of centrifugal force to prevent the high-hardness metal chips from continuing to erode the working surface.

[0004] The mechanical seal rings in the prior art are mainly sleeved on the surfaces of the inlet and outlet pipes on both sides, and then the gaskets are filled in the middle to achieve sealing. However, this sealing method cannot effectively utilize the structural characteristics of the inlet and outlet pipes for self-installation, and the structural design is structurally redundant. Therefore, this design has defects in the integrated design of the transmission pipeline. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Example 1: Reference Figure 1 - Figure 4 , a containerized mechanical seal ring, comprising an input pipe 1 and an output pipe 2, the input pipe 1 and the output pipe 2 are both sides of the pipeline that need to be sealed, and also includes:

[0026] Embedded seal 3, this structure changes the over-design of traditional seals, and cannot fully utilize the structural characteristics of the docking parts for targeted installation, thus causing the problem of structural redundancy. The embedded seal 3 includes an internal thread 15 arranged on the inner side of the input pipe 1 and the output pipe 2. The internal thread 15 cooperates with the external thread 6 to realize the embedded setting of the embedded pipe 5. A lining plate 4 structure is arranged on one side of the input pipe 1 and the output pipe 2. The lining plate 4 itself serves as a flange mounting structure of the pipeline and is converted into an auxiliary installation structure by the device; the surface of the internal thread 15 is screwed and installed with the embedded pipe 5, and external threads 6 are arranged on both sides of the embedded pipe 5. A base 7 is arranged in the middle part of the embedded pipe 5, and the base 7 is docked with the lining plates 4 on both sides through the filling groove 9, thereby realizing the installation of the gasket 8. Filling grooves 9 are arranged on both sides of the base 7, and a gasket 8 is clamped and installed between the filling groove 9 and the lining plate 4;

[0027] The liner 4 is provided with wing plates 10 on both sides, and the positioning holes 11 on the wing plates 10 are used to achieve the effect of positioning and locking. The wing plates 10 are provided with positioning holes 11 on one side, and screw rods 12 are inserted and installed inside the positioning holes 11 on both sides, and the bolts 13 on both sides of the screw rod 12 play a connecting and fixing effect. Bolts 13 are tightened and installed on both sides of the screw rod 12;

[0028] A spring 14 is sleeved and installed on the surface of the screw rod 12, and the spring 14 has a buffering pre-tightening effect.

[0029] A containerized mechanical seal ring, wherein a screw rod 12 adopts a double-thread structure and is used for mounting bolts 13 on both sides.

[0030] A containerized mechanical seal ring, a mounting groove is provided on a liner 4 at a position corresponding to a filling groove 9, the mounting groove and the filling groove 9 have the same function, and are mainly used for embedded installation of a gasket 8.

[0031] A containerized mechanical seal ring, both sides of a spring 14 are respectively connected and fixed to the liner plates 4 at both ends, thus achieving a buffering effect.

[0032] A containerized mechanical seal ring, wherein the gasket 8 is made of anti-corrosion material to avoid corrosion problems caused by the transmitted material.

[0033] A containerized mechanical seal ring, the length of the external thread 6 = the hydraulic limit extrusion length δ in the pipe. When the liquid in the pipe leaks outward due to pressure reasons, the reserved leakage length can be used for liquid buffering, providing a buffer space for the gasket 8.

[0034] In the process of actual innovative design, the utility model proposes an embedded seal 3 structure in order to solve the following defects in the prior art: "The mechanical seal ring of the prior art is mainly sleeved on the surface of the inlet and outlet pipes on both sides, and then the gasket is filled in the middle to achieve sealing. However, this sealing method cannot effectively utilize the structural characteristics of the inlet and outlet pipes for self-installation, and is structurally redundant in structural design. Therefore, this design has defects in the integrated design of the transmission pipeline."

[0035] We make full use of the liner 4 structure of the traditional input pipe 1 and output pipe 2, and set internal threads inside the input pipe 1 and output pipe 2 for docking with the external threads 6 of the embedded pipe 5. This docking design of the flow channel can control the possible leakage site to the inner side of the input pipe 1 and output pipe 2, thereby reserving a buffer zone for the subsequent gasket 8 to prevent leakage, avoiding the problem of sealing failure caused by excessive impact force;

[0036] In order to make full use of the effect of the liner 4 (or flange), we designed a boss-type base 7 structure in the middle of the embedded tube 5, and opened filling grooves 9 on both sides of the base 7. The space between the filling groove 9 and the liner 4 is fully utilized - the gasket 8 is installed, and the gasket 8 plays a direct sealing effect;

[0037] In order to achieve locking, the wing plate 10 structure of the lining plate 4 is still used, and the fixing is achieved through the screw 12 and the bolt 13. The spring 14 sleeved on the surface of the screw 12 has a buffering effect, avoiding the problem of tightening failure caused by excessive contact strength, and at the same time has a certain buffering effect.
