Description

Technical Field

[0001] The utility model relates to the technical field of thermal power, in particular to a pipeline leakage prevention device. Background Art

[0002] Thermal pipelines are used to transport heat media, primarily for heat transfer in centralized heating systems or industrial production. Pipes are widely used in industrial technology and everyday life, transporting gases, liquids, and fluids containing solid particles. Pipes are used in a wide range of applications, including water supply, drainage, heating, gas supply, long-distance oil and natural gas transportation, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] Patent publication number CN215596640U discloses a pipeline leak-proof installation device, including a first pipeline, a first connecting mechanism, a first clamping member, a second connecting mechanism, a second clamping member and a rubber sealing ring. The first clamping member and the second clamping member are conveniently fixed and disassembled through the connection and cooperation of the second screw and the first nut. Through the connection and cooperation of the first screw and the first nut, the first screw is rotated so that the first screw and the first nut squeeze the first clamping member in the first connecting mechanism and the second connecting mechanism, and at the same time, the first screw and the first nut squeeze the second clamping member in the first connecting mechanism and the second connecting mechanism.

[0004] In order to solve the problem that when two pipes for conveying water are connected, the connection stability is poor, the connection between the two pipes is easily loosened, and the sealing of the connection between the two pipes is poor, the existing technology adopts a method of using a first screw and a first nut to connect and cooperate, so that the first screw and the first nut squeeze the first clamping member in the first connecting mechanism and the second connecting mechanism, so that the first pipe and the second pipe are stably connected and not easy to loosen. However, there is still a situation where the device is not suitable for a variety of pipes and cannot be reinforced in the pipe, which leads to incomplete leakage prevention and easily causes water leakage and loss.
