Description

Technical Field

[0001] This utility model belongs to the technical field of high-pressure environment sealing measurement equipment, specifically relating to a pressure vessel through-hole sealing device for measuring lines. Background Technology

[0002] In high-pressure related scientific research or production processes, it is often necessary to perform in-situ measurements of the physical or chemical parameters of materials under high-pressure environments. Pressure vessels can reach pressures of 10 MPa or even higher; therefore, they are generally made of metal, which affects wireless signal transmission. Data acquisition and transmission must be performed using measuring cables. Sensors transmit signals to measuring equipment outside the pressure vessel via measuring leads, a process that involves the measuring cable passing through the pressure vessel. If the sealing device malfunctions, it will lead to instability in the internal pressure of the pressure vessel, causing experimental errors and safety hazards. These problems affect the reliability of measurement results and the safety of the experimental process, and may even threaten the safety of operators.

[0003] Existing high-pressure sealing devices are generally single-wire measurements, meaning that a fixed number of measuring wires of a certain diameter are used to maintain a seal. However, in practical applications, due to differences in the physical quantities being measured, the required sensor measuring wire diameters and numbers vary. In such cases, existing sealing devices struggle to adapt to the sealing requirements of different measuring wires and cannot achieve reliable sealing measurements. Utility Model Content

[0009] A second sealing nut is threaded to the outer end of the sealing cylinder near the pressure vessel, and a first sealing nut is threaded to the outer end of the sealing cylinder away from the pressure vessel.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

Figure 3 As shown, several mechanical bolts 6 are installed at equal intervals on the outer periphery of the sealing cylinder 5. A pressure vessel 7 is threaded to one end of the sealing cylinder 5. A sealing wire bundle 1 is threaded through the sealing cylinder 5, and a sealing material is wrapped around the sealing wire bundle 1.

[0033] A rubber gasket 9 is fitted at the connection between the sealing cylinder 5 and the pressure vessel 7.

[0034] The number of mechanical bolts 6 is even.

[0035] like Figure 4 As shown, the sealing material includes a first sealing material 3, such as... Figure 5 As shown, the inner diameter of the first sealing material 3 matches the diameter of the sealing wire harness 1. The bottom of the first sealing material 3 is outwardly expanded, and the outwardly expanded part of the first sealing material 3 is stuck in the port of the sealing cylinder 5 near the pressure vessel 7. The top of the first sealing material 3 has a snap-fit ​​structure, and the second sealing material 4 is installed on the top of the first sealing material 3 by snap-fit.

[0036] like Figures 6-7 As shown, the top of the second sealing material 4 is outwardly expanded, and the bottom has a snap-fit ​​structure. The outwardly expanded part of the second sealing material 4 is stuck at the port of the sealing cylinder 5 away from the pressure vessel 7.

[0037] Both the first sealing material 3 and the second sealing material 4 are rubber materials, which have high elasticity, wear resistance, excellent sealing performance, temperature resistance and corrosion resistance, and can maintain excellent performance under the wear of various media in high pressure environment.

[0038] The outer end of the sealing cylinder 5, close to the pressure vessel 7, is threaded with a second sealing nut 8. Mechanical force compresses the first sealing material 3 to complete the secondary seal. The outer end of the sealing cylinder 5, away from the pressure vessel 7, is threaded with a first sealing nut 2. Mechanical force compresses the second sealing material 4 to complete the tertiary seal.

Figures 8-9 As shown, both the first sealing nut 2 and the second sealing nut 8 have chamfers. During rotation, they continuously compress the outward expansion of the first sealing material 3 and the second sealing material 4 to achieve a mechanical sealing effect.

[0040] The sealed wire harness 1 includes a wire harness 11 composed of wires of different diameters, with the larger diameter wires in the middle and the smaller diameter wires around the perimeter, which can effectively reduce the gaps between the wire harnesses and prevent the risk of leakage. The outer perimeter of the wire harness 11 is covered with waterproof material, which is matched to the type of medium in the pressure vessel.

[0041] The pressure vessel through-hole sealing device for measuring lines provided by this utility model works on the following principle: Figure 11 As shown, the wire bundles 11 of different diameters are fixed in an arrangement where the larger diameter is in the middle and the smaller diameter is around the perimeter, effectively reducing gaps between the wire bundles and minimizing leakage. They are then secured with waterproof material 12, completing the initial seal. Figure 12 As shown, the sealing cylinder 5 is threaded onto the pressure vessel 7; the sealing wire harness 1 is sequentially threaded through the second sealing nut 8 and the first sealing material 3, and the second sealing nut 8 is fixed to the pressure vessel end of the sealing cylinder 5. Mechanical force is used to press the first sealing material 3, completing the secondary seal; the sealing wire harness 1 is sequentially threaded through the second sealing material 4 and the first sealing nut 2, and the lower end of the second sealing material 4 is installed at the snap-fit ​​position of the first sealing material 3. The first sealing nut 2 is fixed to the air end of the sealing cylinder 5, and mechanical force is used to press the second sealing material 4, completing the tertiary seal; as shown... Figure 13 As shown, the rotating mechanical bolt 6 is pressed onto the first sealing material 3 by mechanical force, thus completing the fourth sealing by mechanical force.
