Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of pipeline plugging, and relates to a heat conducting oil pipeline leak stoppage device. BACKGROUND

[0002] Heat conducting oil is a commonly used industrial heat medium, which is widely applied to high-temperature processing in the fields of chemical industry, pharmacy, tire and paint, but there are problems such as heat coupling, pipeline corrosion and poor welding quality, which cause heat conducting oil pipeline leakage and lead to many safety problems.

[0003] When the pipeline surface leaks, the prior art often uses a half joint to plug, for example, the document (Discussion on Pipeline Leak Stopper--Half Joint Pipeline Repair Technology [J], Shandong Industry Technology.) records the repair technology of the half joint, the half joint mainly comprises an upper cover, a lower cover, an O-shaped sealing ring and a bolt and a nut, the upper cover and the lower cover are attached to the petroleum pipeline at the leakage position, the bolt is passed through the upper cover and the lower cover, and the nut is tightened on the bolt, so that the upper cover and the lower cover drive the O-shaped sealing ring to tightly attach to the surface of the petroleum pipeline, thereby forming a seal at the leakage position and realizing the plugging of the pipeline.

[0004] However, when facing the heat conducting oil pipeline, the half joint cannot well seal the leakage point, and the high-temperature heat conducting oil in the heat conducting oil pipeline can easily penetrate the flexible O-shaped sealing ring, thereby causing leakage, and even if a high-temperature-resistant O-shaped sealing ring is used, the leakage cannot be blocked because the high-temperature heat conducting oil is corrosive to rubber.

[0005] Therefore, it is of great significance to research a heat conducting oil pipeline leak stoppage device to solve the above problems. UTILITY MODEL CONTENTS

[0006] The utility model aims at solving the problems in the prior art and provides a heat conducting oil pipeline leak stoppage device.
