Problems solved by technology
[0004] The disadvantage of the existing technology is that a new sealed cavity is formed between the clamp and the outer wall of the oil pipeline during non-stop maintenance, and the pressure in the sealed cavity is consistent with the pressure inside the oil pipeline, so that the pressure between the clamp and the oil pipeline New leak points are prone to appear at the joints of pipelines, which cannot be effectively dealt with by existing technologies

Embodiment Construction
[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0034] Such as Figure 1-9 As shown, an emergency treatment device for leakage of oil pipeline 8 provided by the embodiment of the present invention includes a ring clamp 1 used for sealing and clamping on the outer wall of oil pipeline 8, and the inner surface of the ring clamp 1 It forms a sealed cavity with the outer surface of the oil passage, and the annular clamp 1 is connected with a pressure relief passage 2, and the pressure relief passage 2 communicates with the oil emergency storage mechanism 3; the pressure relief passage 2 is provided with a passive opening Mechanism 4, the passive opening mechanism 4 passively opens the pressure relief channel 2 when receiving a rated pressure; the rated pressure is between 0.8-1.1 times the working ...

The invention discloses an emergency disposal device for oil product pipeline leakage. The device comprises an annular clamp for sealing and being clamped on the outer wall of an oil product pipeline,the inner side surface of the annular clamp and the outer side surface of an oil product channel form a sealing cavity, the annular clamp is connected with a pressure relief channel, and the pressurerelief channel communicates with an oil product emergency storage mechanism; the pressure relief channel is provided with a passive opening mechanism, and the passive opening mechanism passively opens the pressure relief channel when receiving rated pressure; and the rated pressure is 0.8-1.1 times of the working pressure of the oil product pipeline. According to the emergency disposal device forthe oil product pipeline leakage, when the pressure in the sealing cavity is too large to cause a new leakage point to possibly occur, the passive opening mechanism is opened to convey an oil productin the sealing cavity to the emergency storage mechanism for storage through the pressure relief channel, so that the pressure in the sealing cavity is reduced, and the probability of the occurrenceof the new leakage point is reduced.
Description
technical field [0001] The invention relates to oil product delivery technology, in particular to an emergency treatment device for oil product pipeline leakage. Background technique [0002] Shipping and pipeline transportation are the two main transportation methods of oil products, among which pipeline transportation is mainly used on land, such as the oil product transportation pipeline from Xinjiang to the mainland, the oil product transportation pipeline from Russia to the Northeast, etc., which are all important in my country. Energy arteries. [0003] It is known that some oil pipelines were built at the turn of the century. Due to the material technology at that time, the long service life and the corrosion of oil products, oil pipelines often leak. The maintenance methods for pipeline leakage in the prior art are as follows: There are two types: non-stop maintenance and non-stop maintenance. Obviously, the loss caused by non-stop maintenance is smaller. The current...
