Device and method for detecting product pipeline leakage condition

Abstract

The invention relates to a device and a method for detecting product pipeline leakage condition. The device comprises a throttling valve (1), a pressure transmitter (2), a connecting assembly (3), a ball valve (4), a tubular main body (5), a pressure transmitter power supply (6), a recorder (7), a safety valve (8) and a blind plate assembly (9), wherein the ball valve (4) is arranged between the pressure transmitter (2) and the tubular main body (5); the pressure transmitter (2) is connected with the pressure transmitter power supply (6) and the recorder (7) to form a loop; the connecting assembly (3) comprises a connecting pipe, a flange interface, a sealing ring, a pipe clamp or a loose joint; the detection device is clamped or screwed on a detected pipeline through the flange interface of the connecting assembly (3); and the recorder (7) is a digital display recorder with alarm function. The device has good sealing property, is accurate and convenient to detect, and overcomes the defects of poor sealing property and sterile pipeline inapplicability of other detection equipment.

Description

technical field [0001] The invention relates to the field of pipeline leakage detection, in particular to a device for detecting product pipeline leakage and a detection method thereof. Background technique [0002] At present, a large number of pipes are used in industrial production as liquid and gas transmission channels, and a large number of pipes are also used in heat exchangers. Leakage often occurs due to corrosion of pipes or damage due to other reasons. The accident caused the equipment not to work normally, but the current factory does not have a special device for detecting the leakage of the sterile pipeline of the product. When the sterile pipeline of the product leaks, it can only be observed visually. This method is not effective. When Tetra Pak High-temperature sterilization machine tube heat exchangers and APV ultra-high temperature sterilization machine tube heat exchangers cannot be detected for internal leakage, and the workload of dismantling and repair...

[0002] At present, a large number of pipes are used in industrial production as liquid and gas transmission channels, and a large number of pipes are also used in heat exchangers. Leakage often occurs due to corrosion of pipes or damage due to other reasons. The accident caused the equipment not to work normally, but the current factory does not have a special device for detecting the leakage of the sterile pipeline of the product. When the sterile pipeline of the product leaks, it can only be observed visually. This method is not effective. When Tetra Pak High-temperature sterilization machine tube heat exchangers and APV ultra-high temperature sterilization machine tube heat exchangers cannot be detected for internal leakage, and the workload of dismantling and repairing large-scale exchangers is very heavy, which brings a lot of inconvenience, so this test is invented device
