When the hydraulic supports need unload through one-way valve which controlled by liquid pressure, they will bring exquisite pressure concussion、vibration and yawp the life-span of one-way valve which controlled by liquid pressure and the system of hydraulic support decreased sharply.
这极大的影响了液控单向阀和液压支架系统的使用寿命。
