Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline monitoring equipment, in particular to a water pressure monitoring device for pipeline weld joint detection. BACKGROUND

[0002] When laying a conveying pipeline, the joints between adjacent pipelines need to be welded. The quality of the weld joint depends on the welding technology of the personnel. The weld joint is usually the weak point of the overall conveying pipeline. Under the influence of geological action and other factors, cracks may occur at the weld joint, thus it is necessary to use a detection device to monitor the weld joint in real time so that maintenance personnel can discover the leakage in time.

[0003] The existing pipeline is only detected by a detection device after welding. However, when the pipeline is used for a long time, the weld joint is not monitored by any monitoring device. If a crack occurs at the weld joint, the liquid conveyed in the pipeline will leak, and the maintenance personnel cannot discover the leakage in time.

[0004] Therefore, the present application provides a water pressure monitoring device for pipeline weld joint detection to solve the above problems. CONTENT OF THE UTILITY MODEL

The liquid storage tank is mainly used for recovering the clean water in the upper cover and the lower cover after the clean water is discharged outwards by the pressure relief valve. If the pipeline body does not have cracks and leaks, the recovered clean water can be used again.

[0010] Preferably, the upper cover is symmetrically provided with a first mounting seat, the lower cover is symmetrically provided with a second mounting seat corresponding to the first mounting seat, and the second mounting seat is fixedly connected with the first mounting seat by bolts.
