[0002] With the continuous increase in my country's railway transportation volume, the problem of rail wear has become a difficult problem that troubles the engineering department, especially in some small-radius curves with high traffic density. The tangential force increases when the train passes through the curve. According to the principle of friction, the greater the contact stress between the rubbing objects, the greater the loss caused by friction. The increasingly serious rail wear not only greatly increases the investment in maintenance costs, but also constantly endangers driving safety. The most important factor affecting the service life of rails on curves is rail side wear, especially for rails with a small curvature radius. To solve the above problem, it is generally achieved by spraying a lubricating medium to improve the interaction between the wheel and rail to achieve the purpose of delaying rail side wear.

A clamping groove corresponding to the arc-shaped clamping rod 19 is provided on the fixing block 17. A torsion spring is sleeved on the pin shaft 18. The two ends of the torsion spring are respectively against the arc-shaped clamping rod 19 and the main valve body 1, thereby providing torsional support for the arc-shaped clamping rod 19.
