Double-layer oil tank with online leakage detection function and detection and preparation process of the double-layer oil tank

Abstract

The invention discloses a double-layer oil tank with an online leakage detection function and a detection and preparation process of the double-layer oil tank. The double-layer oil tank comprises an inner shell 1, an outer shell 2 and a middle layer located between the inner shell 1 and the outer shell 2; a detection tube 102 is inserted into a guide tube 101 and then communicates with the middlelayer, a detector 104 is inserted into the detection tube 102, a plurality of optical fibers 201 are evenly and tightly wound around the outer wall of the outer shell 2, and the head and tail ends ofeach optical fiber 201 are led out from a contact point between a wire slot 101.1 of the guide tube 101 and the outer shell 2, are led into the guide tube 101 through the wire slot 101.1 and a threading notch 101.2, are combined with a cable led out from the detector 104, and then are led out through a lead hole 106.1. According to the double-layer oil tank with the online leakage detection function and the detection and preparation process of the double-layer oil tank, leakage of the inner shell and the outer shell can be effectively distinguished, and leakage points can be sensed while leakage occurs.

Description

technical field [0001] The invention relates to a double-layer oil tank with an on-line leak detection function and a detection and preparation process thereof, belonging to the technical field of oil tanks. Background technique [0002] At present, double-layer oil tanks must have a leak detection function (used to detect the leakage of the middle layer). The conventional leak detection method is: sensor method (used for SF oil tanks), using a pressure sensor to detect the pressure of the middle layer; Medium method (for FF oil tank), brine is poured into the middle layer as the detection medium; vacuum method (for FF oil tank), the middle layer is vacuumed to form a vacuum layer. [0003] The present invention is based on the SF oil tank. In practical application, it is found that the sensor of the SF oil tank can only detect whether there is leakage, but the leakage point occurs between the outer shell and the inner shell and cannot be distinguished in a timely and effect...

Problems solved by technology

[0003] The present invention is based on the SF oil tank. In practical application, it is found that the sensor of the SF oil tank can only detect whether there is leakage, but the leakage point occurs between the outer shell and the inner shell and cannot be distinguished in a timely and effective manner, and the barrel It is impossible to effectively know where the body leakage point occurs, so that it is impossible to effectively evaluate its safety performance. Therefore, there are huge deficiencies and urgent improvement is needed.
