| description | The invention discloses an anti-erosion device based on a stab-proof function of a fairing, which mainly comprises a hemispherical fairing, a buffer chamber and a fixed bracket, and can be additionally arranged at the connecting part of an elbow and a straight pipe section in a bent pipe to efficiently improve the anti-erosion performance of the bent pipe. The anti-erosion device designed by the invention is simple to mount and remarkable in effect, the original motion trail of particles is changed under the puncture-proof and shunting effects of the fairing, the particles directly impacting the elbow part of the elbow can be adsorbed into the buffer chamber, and the particles move around the flow to form a low-speed countercurrent area, so that the erosion is relieved. Due to the existence of the fairing, the internal flow field of the pipeline behind the fairing is changed, the turbulent kinetic energy is obviously increased, the movement of particles is more easily interfered by fluid, the erosive wear of |
