Embodiment Construction

[0018] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0019] figure 1 The composite pipeline compensator shown in the figure has a diameter of 3500mm and is matched with the diversion pipeline of a hydropower station in the south. The composite pipeline compensator is composed of two different types of compensators, which include inner pipe 1, packing 2, outer shell 3, bellows 4, armor ring 5, liner 6, filling port 7 and slip ring 8. The bellows 4 is a typical thin-walled elastic element. In order to further strengthen the bellows 4, an armor ring 5 is placed inside the outer trough of the bellows 4 in the lying position. Two corrugated pipes 4 of the same specification are connected in series coaxially, and a liner 6 is provided on the inner wall of the two connected corrugated pipes 4 to conduct flow. The shell 3 is a cylindrical body with a large middle and small ends. The middle sect...

Abstract

The invention discloses a duplex pipeline compensator. The duplex pipeline compensator comprises an inner pipe, packing, a shell, a pair of corrugated pipes, amour rings, liner pipes, filling holes, and sliding rings, wherein the amour rings are arranged in outer valleys of the corrugated pipes, the liner pipes are arranged in the pair of corrugated pipes which are coaxially connected in series, and the two ends of the corrugated pipes are connected with inner pipes in a sealed mode, so that the corrugated compensator is formed. The inner walls of the two ends of the shell are respectively provided with a sealing cavity which is composed of an inner shoulder and an outer shoulder, the packing and the sliding rings are embedded in the sealing cavities, and the filing holes are evenly distributed on the outer walls of the two ends of the shell. The shell is arranged on the outer wall of the corrugated compensator in a sleeved mode, the sealing cavities in the two ends of the shell are matched with the outer walls of the inner pipes matched with the shell to form sleeve type compensators, and in this way, the corrugated compensator is protected by the two sleeve type compensators. Due to the integrated design of the duplex independent compensation structure, safety production can be effectively achieved, the frequency of halt maintenance is reduced, and the operating efficiency of a water leading pipeline of a hydropower station is improved.

Description

technical field [0001] The invention relates to a pipeline safety device, in particular, the invention relates to a pipeline compensator matched in a water diversion pipeline of a hydropower station. Background technique [0002] By laying large-diameter water diversion pipes, the hydropower station leads the water source from the upper reaches of the reservoir to the main building of the power plant at the bottom of the dam, and uses the potential energy of the high-level water flow to convert into kinetic energy to drive the hydroelectric generator to generate electricity. The water level difference between the entrance of the water diversion pipeline and the main powerhouse in the project is usually hundreds of meters, or even thousands of meters. The greater the water level difference, the greater the potential energy, and the greater the work done by driving the hydroelectric generator. Most of the water diversion pipes supporting the hydropower station run through the ...
