Embodiment

[0032] Such as figure 1 As shown, the high-pressure pipeline slamming device includes six parts: the active pipe 9, the driven pipe 15, the air compressor 1, the release device 12, the supporting device and the measuring device, wherein the supporting device is responsible for the hinge of one end of the active pipe 9 and the driven pipe 15. Both ends are fixed, the air compressor 1 is connected to the hinged end of the active tube 9, presses high-pressure air into the active tube 9 and sprays out from the free end, the release device 12 connects the free end of the active tube 9 and the top of the guide rail 11, when the high-pressure gas is ejected Unlock and release the active tube 9, so that it swings at high speed under the recoil force and collides with the driven tube 15. The measuring devices are distributed on both sides of the active tube 9 and the driven tube 15, and relevant data are recorded during the impact process.

Abstract

The invention discloses a high-pressure pipe whipping device, in particular relates to a dynamic test device in which a pressure pipe whips under the effect of escape and backlash of the internal high-pressure gas, and belongs to the technical field of dynamic tests. The device includes an active pipe, a passive pipe, a support device, an air compressor, release device and a measuring device, wherein the support device includes a box iron platform, a derive pipe fixed support, a fixture, a bolt, a bearing, a roll shaft and a passive pipe fixed support; the measuring device is composed of a high-speed camera, a strain gage, a dynamic strain indicator, an oscilloscope and a laser velometer; a high-pressure solenoid valve releases high-pressure air to enter into the active pipe and to be sprayed out from the free end of the active pipe, the release device is delocked for releasing due to the backlash acting force, the active pipe whips and dashes against the active pipe, and the measuring device records the dashing process in real time.

Description

technical field [0001] The invention relates to a high-pressure pipeline slamming device, in particular to a dynamic test device for a pressure pipeline to slam into another pipeline under the recoil action of internal high-pressure gas leakage, and belongs to the technical field of dynamic testing. Background technique [0002] Pipelines are widely used in important industrial sectors such as nuclear power plants, petrochemicals, gas and civil construction, and are responsible for transporting large quantities of high-energy (high temperature, high pressure) liquids and gases. Pressure pipe networks have constituted the arteries of these industrial sectors. However, due to various accidents, impacts of objects or the impact of fragments generated after explosions, the pressure pipes are partially ruptured, which will cause the internal high-pressure liquid or gas to leak out. Small-scale leakage of high-pressure liquid or gas may cause environmental pollution, and large-sca...
