Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing rings, in particular to a novel drum-type pressurized multi-ring composite sealing ring. Background Art
[0002] The sealing ring has a sealing function and can seal gas and liquid. According to the material, there are sealing rings made of NBR nitrile rubber sealing rings, SIL silicone rubber sealing rings, etc. According to the shape, there are sealing rings in V-shaped, U-shaped, O-shaped, rectangular, Y-shaped, etc. The atomizer is the core component of the ultrasonic atomizer device and is usually used in conjunction with a water-proof rubber ring.
[0003] The existing sealing ring has a relatively simple structure. Especially when used in some high-pressure environments, or during the installation process due to excessive connection pressure, the sealing ring may be deformed or even damaged, thereby reducing its sealing effect and service life.
[0004] Therefore, we propose a new drum-type pressurized multi-ring composite seal. Utility Model Content
[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a novel drum-type pressurized multi-ring composite sealing ring.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a novel drum-type pressurized multi-ring composite sealing ring, comprising a sealing inner ring, the outer wall of the sealing inner ring is fixedly installed with a connecting sleeve ring that can be connected, the outer wall of the connecting sleeve ring is movably sleeved with a sealing outer ring that can be sealed, the outer wall of the connecting sleeve ring is provided with a threaded groove, the outer wall of the connecting sleeve ring is provided with a first limiting ring and a second limiting ring that can be limited, the connecting sleeve ring, the first limiting ring and the second limiting ring are all made of steel material, the second limiting ring is located at the lower side of the sealing outer ring, the first limiting ring is located at the upper side of the sealing outer ring, the first limiting ring and the second limiting ring are both provided with a threaded groove that can be positioned, the first limiting ring and the second limiting ring are both threadedly connected to the connecting sleeve ring, the outer wall of the connecting sleeve ring is fixedly installed with a limiting block that can be limited, the inner wall of the sealing outer ring is provided with a limiting slot that can be limited, the limiting block and the limiting slot are adapted to each other, and the limiting block is movably inserted into the inner part of the limiting slot.
[0007] Preferably, the sealing inner ring includes a corrosion-resistant layer, a high-pressure-resistant layer, a silicon material reinforcement layer, an anti-aging layer, a metal reinforcement layer and a composite material layer.
[0008] Preferably, the high-pressure resistant layer is fixedly installed on the outer wall of the corrosion-resistant layer, the silicon material reinforcement layer is fixedly installed on the outer wall of the high-pressure resistant layer, and the anti-aging layer is fixedly installed on the outer wall of the silicon material reinforcement layer.
[0009] Preferably, the metal reinforcement layer is fixedly mounted on the outer wall of the anti-aging layer, and the composite material layer is fixedly mounted on the outer wall of the metal reinforcement layer.
[0010] Preferably, the corrosion-resistant layer is made of polytetrafluoroethylene material. Polytetrafluoroethylene has no real melting point and will slowly decompose at a temperature above 450°C. Its performance at room temperature and pressure is very stable, so it can be used in many high-temperature operations, especially some factory processing and manufacturing operations. Not only that, polytetrafluoroethylene is also resistant to low temperatures. Even if the temperature drops to minus 196°C, it can maintain good mechanical toughness and elongation, which not only improves the corrosion resistance, but also improves the high and low pressure resistance function and increases its service life.

[0012] Beneficial Effects

[0014] (1) This novel drum-type pressurized multi-ring composite sealing ring can improve the overall sealing effect by cooperating with the sealing inner ring and the sealing outer ring when in use. Since the connecting ring, the first limiting ring and the second limiting ring are all made of steel material, the overall rigidity can be increased, the deformation resistance and high and low pressure resistance can be improved, and the sealing effect and service life can be improved. In addition, since the limiting block is movably inserted into the inside of the limiting groove, the stability of the sealing outer ring on the outer wall of the connecting ring can be improved.
[0015] (2) This novel drum-type pressurized multi-ring composite seal ring has a corrosion-resistant layer made of polytetrafluoroethylene material when in use. Polytetrafluoroethylene has no real melting point and will slowly decompose when the temperature exceeds ℃. Its performance at room temperature and pressure is very stable, so it can be used in many high-temperature operations, especially some factory processing and manufacturing operations. Moreover, polytetrafluoroethylene can also withstand low temperatures. Even if the temperature drops to below zero ℃, it can still maintain good mechanical toughness and elongation, which not only improves the corrosion resistance, but also improves the high and low pressure resistance function and increases its service life. The anti-aging layer is made of EPDM material. EPDM material has the characteristics of low density and high filling, and can be filled with a large amount of oil and fillers, thereby reducing the cost of rubber products.
