Description

Technical Field

[0001] This utility model relates to the field of metal hose technology, specifically to an anti-vibration metal hose for oil storage tanks. Background Technology

[0002] With the development of modern technology, metal hoses are being used more and more widely in engineering, and are widely used in metallurgy, petrochemical industry, aerospace and other fields. In particular, in the chemical industry, the settlement of the oil storage tank foundation, the multi-directional displacement caused by thermal expansion and contraction between the oil storage tank and the pipeline, and natural disasters such as earthquakes will all directly affect the safety of the medium transmission process in the oil storage tank.

[0003] In the case of existing metal hoses, when subjected to severe vibrations caused by earthquakes or human activities, as well as the corresponding vibrations in the oil storage tank itself due to mechanical operation, the weld between the hose and the corrugated pipe may be twisted or even broken due to defects, which seriously affects the performance and service life. Furthermore, the sealing performance of the hose is insufficient after long-term use. Therefore, we propose an anti-vibration metal hose for oil storage tanks. Utility Model Content

[0004] In view of the problems existing in the current anti-vibration metal hoses for oil storage tanks, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an anti-vibration metal hose for oil storage tanks, which solves the problem that the weld between the hose and the corrugated pipe is twisted and eventually breaks due to defects.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-vibration metal hose for an oil storage tank includes two flanges, a spring fixed between the two flanges, a protective sleeve fixed to the outside of the flanges, the inner wall of the protective sleeve fitting against the outside of the spring, a sealing seat fixed to the outer wall of the flanges, a hose fixed to the outside of the sealing seat, a threaded seat rotatably provided on one side of the flanges, and two telescopic rods fixed between the two flanges.

[0008] Preferably, a first sealing gasket is fixedly provided on the inner side wall of the protective sleeve, and the first sealing gasket is fixedly connected to the flange.

[0009] Preferably, a sealing ring is fixedly provided at one end of each of the two telescopic rods, and the sealing ring is slidably connected to the moving end of the telescopic rod.

[0010] Preferably, a second sealing gasket is fixedly provided on the inner side wall of the threaded seat, and both the first sealing gasket and the second sealing gasket are made of silicone.

[0011] Furthermore, the protective sleeve is made of rubber.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] This utility model features an advanced design, ease of processing, good resistance to thermal cracking, high weld strength, and no stress concentration. It can absorb vibration, thermal expansion, and reciprocating motion in harsh working environments, exhibiting excellent seismic performance. It effectively compensates for the settlement of oil tank foundations and multi-directional displacement caused by thermal expansion and contraction between the tank and pipelines, thus providing shock absorption. It also reduces noise. Applied to the connection points between oil storage tanks and pipelines in the petrochemical industry, it offers high safety performance and a long service life.
