掘进机抗弯矩管道开关结构的设计

Design of Anti-Bending Pipe Valve Structural for Roadheader

悬臂梁结构支撑处有密封,长时间受弯矩作用,密封会磨损,导致密封失效。以某矿用掘进机供水系统中的球阀开关控制结构,探讨球阀轴不受弯矩的结构,延长球阀使用寿命,避免密封经常损坏。

The sealing on a cantilever structure may be worn out to failure due to the bending action in a long time. Takes the pipe globe valve in the water supply system of a roadheader as an example, develops an anti- bending structure to prolong the service life of the valve and avoids the frequent loss of its sealing.
