Abstract

The invention provides a flow guiding platform conical valve for a retarder, and relates to a flow guiding platform conical valve. The problems that the impact force of instant hydraulic flow of a high-load retarder on the existing conical valve is over large, so that off-line accidents are easily caused, and shunting service is dangerous are solved. A valve body of the flow guiding platform conical valve comprises a cone and a flow guiding platform, wherein the flow guiding platform is a columnar platform; the cone and the flow guiding platform are sequentially arranged fixedly from top to bottom; a step inner cavity is formed in the flow guiding platform; a through hole is formed in the upper portion of the flow guiding platform and is perpendicular to the flow guiding platform; a plurality of grooves are sequentially formed in the lower portion of the flow guiding platform from top to bottom along the outer side wall of the flow guiding platform; a cone pressure-relief arc-shaped groove is formed in the cone and in an intersection of the cone and the flow guiding platform; a platform pressure-relief arc-shaped groove is formed in the flow guiding platform and in an intersection of the cone and the flow guiding platform; and the cone pressure-relief arc-shaped groove is adjacent to the platform pressure-relief arc-shaped groove. The flow guiding platform conical valve is used for the retarder.

Description

technical field [0001] The invention relates to a diversion platform cone valve, in particular to a diversion platform cone valve for a high-load deceleration roof. Background technique [0002] With the development requirements of high-speed and heavy-duty railways at home and abroad, the speed-regulating equipment of high-load series deceleration jacks has been widely promoted and applied. The pressure valve is one of the core components of the high-load retarder, which directly determines whether the work of the high-load retarder is stable. However, due to the large hydraulic flow rate of the high-load deceleration top, the ordinary pressure valve is seriously affected by the hydraulic power, especially at high speeds, it is easy to generate excessive vertical reaction force that endangers driving safety. When the wheel passes through the head of the sliding cylinder, it is easy to cause Accidents such as off-lines occur, which brings danger to shunting operations. The...
