Problems solved by technology

And once this happens, according to the current technology, the emergency repair personnel not only cannot get close to the injection site, but also because of the high injection pressure, it is impossible to cover the drainage cover with manual force, let alone block it, so they have to let the oil Repair after spraying

Embodiment Construction

[0018] Embodiment. The specific embodiment of the present invention is described with this example and the present invention is described further. This example is an experimental prototype, its structure is as follows figure 1 shown.

[0019] In actual application, according to the diameter of the pipeline, the surrounding environment of the pipeline and the leakage situation, the size range of the oil collection port of the leakage control recovery device is specifically determined, and a series of leakage control recovery devices are designed. Generally, the diameter D is not greater than 1000mm. In this example, the diameter D=420mm is selected, and the structure of the leakage control recovery device is a straight cone structure with a cone angle of 60 degrees. 60mm wide ring edge, thin end Φ36mm, length 150mm; 10 protective claws 2 are fixed on the ring edge of the bell mouth of the oil collecting cover 1, each protective claw 2 is 132mm wide and 131mm apart, and is made...

Abstract

The invention relates to a products pipelines leakage control retriever for exerting control after the products pipelines leaked relating to the technical field of pipeline system. The invention is composed of an oil collecting cap [1], a defending jaw [2], a pin-shaped pinnacle [3], a connecting strengthen component [4] and an oil collecting pipe [5]; wherein, a fine end of the cone straight tube-shaped oil collecting cap [1] is connected with the oil collecting pipe [5] and the rough end has ring edges vertical to a central axes of the cone straight tube around; a plurality of defending jaws [2] are mounted on the ring edges in interval and the pin-shaped pinnacle [3] are densely distributed between the defending jaws [2]; the connecting strengthen components [5] are connected at external circumference of the oil collecting cap [1]. The invention has the advantages of high and reliable oil collecting efficiency, good anti-detonation performance, safety, low cost and practicality.

Description

technical field [0001] The invention is a recovery device for controlling the leakage of the product oil pipeline after the leakage of the product oil pipeline. It relates to the technical field of piping systems. Background technique [0002] Leakage control is an important means to prevent accidents from expanding and reduce accident losses. Once a product oil pipeline leaks, even if it is necessary to stop the transmission and close the line shutoff valves upstream and downstream of the leak point, since the oil pipeline is not on the same level, as long as the leak point is not at the highest point of the cut off pipeline section, there will be an elevation Poor, the leakage point will spray oil due to the static pressure of the pressure difference. When the static pressure reaches a certain level, it will break through the soil layer and spray into the air. This situation is common. The result is not only waste, but also pollute the environment, the consequences are e...
