AI Technical Summary

Problems solved by technology

The thickness of the rubber pad is limited, and the requirements for the contact surface are high during installation. If the pipe wall is deformed, the force on the contact surface will be uneven, and it is difficult to achieve the sealing effect.

Embodiment 1

[0022] Example 1 (vessel and large pipeline plugging):

[0023] figure 1 , figure 2 As shown, a permanent magnetic liquid bag pressure equalization emergency plugging device includes an annular casing 3 with an n-shaped cross section, a liquid-filled bag 8 is arranged in the groove of the casing 3, and a liquid-filled bag 8 is arranged below the liquid-filled bag 8. There is a composite rubber pad 9, and a sealing pad 10 is provided under the composite rubber pad 9; the casing 3 is provided with a liquid injection hole 1, and the liquid injection hole 1 communicates with the liquid-filled bag 8; the outer surface of the casing 3 is evenly distributed with three brackets 4 One end of the bracket 4 is connected with a permanent magnet mechanism 7 by bolts, and the housing 3 located at the other end of the bracket 4 is provided with a guide tube 2, and one end of the guide tube 2 is connected with a flange, and the other end of the guide tube 2 is connected to the ring of the h...

Embodiment 2

[0025] Embodiment 2 (small pipe plugging):

[0026] When a small pipeline leaks, because the permanent magnet mechanism is inconvenient to adsorb on the pipeline, the permanent magnet mechanism can be replaced with a pipe clamp, and the occluder shell is designed to be consistent with the curvature of the pipeline. The pressure equalizing sealing assembly is installed on the pipeline with a pipe clamp, and the liquid bladder makes the force applied by the pipe clamp to the sealing surface all vertical to the sealing surface, so as to achieve the sealing effect.

Embodiment 3

[0027] Embodiment 3 (blocking in special occasions):

[0028] When the leak occurs at a high place or where other personnel cannot reach it, the device can be converted into a device equipped with a mechanical arm, and the automatic control system can realize automatic emergency sealing.

Abstract

The invention relates to a permanent magnetic liquid bag pressure-equalizing emergent plugging apparatus and an emergent plugging method, which are mainly used for emergently plugging a leak opening of a downhand weld and a lap weld of a storage tank, a reaction device and a pipeline. The permanent magnetic liquid bag pressure-equalizing emergent plugging apparatus comprises a guide mechanism, a compressing mechanism and a pressure-equalizing sealing assembly, wherein the guide mechanism is connected with an annular shell of the pressure-equalizing sealing assembly, and a support of the compressing mechanism is connected with the annular shell of the pressure-equalizing sealing assembly by virtue of a universal coupling. The permanent magnetic liquid bag pressure-equalizing emergent plugging apparatus can bear certain pressure, so that the halt production caused by the leakage of a factory pipeline device can be avoided, and the loss is reduced. A leak opening is simple and easy to plug, certain pressure can be born, the popularization value is high, and the social and economic benefit is good.

Description

technical field [0001] The invention belongs to the fields of petrochemical and pipeline engineering safety production, and is mainly used for emergency sealing of the leakage openings of flat welds and lap welds of storage tanks, reaction equipment and pipelines. Background technique [0002] With the development and expansion of the scale of chemical production, the pressure of reaction equipment, storage equipment and pipelines continues to increase, and leakage accidents occur from time to time, causing casualties, environmental pollution and energy waste. Therefore, the emergency plugging of reaction equipment, storage equipment and pipelines It has become a very important link in the process of modern petrochemical production, storage and transportation. It is urgent to quickly, effectively and safely block the leakage of equipment pipelines, so as to effectively control the source of danger and minimize the damage caused by its leakage. Casualties, environmental pollu...
