Zusammenfassung: | The invention discloses a cushion valve comprising a valve body, a valve core and an elastomer. Through the cushion valve, the overload cushioning can be achieved under the condition of considering a braking distance and braking time; the cushion valve has the advantages of simple structure, high environmental adaptability and low cost; the disadvantages of insufficient absorption capacity for pressure fluctuation and complex structure of the traditional two-stage relief valve, poor operational condition adaptability and high price of an electro-hydraulic proportional valve are overcome. The cushion valve is easily applied to mechanical hydraulic buffer systems of farm machines in complex working environment, and the applicability of the cushion valve is improved greatly compared with the existing buffer system.
本发明公开了种阻尼缓冲阀,包括阀体、阀芯及弹性体,该阻尼缓冲阀可以在兼顾制动距离和制动时间的情况下实现过载缓冲,该缓冲阀结构简单、对环境适应性较好,并且成本较低,可以有效克服传统双溢流阀对压力波动吸收能力不足、结构复杂;电液比例阀工况适应性差、价格高昂的缺点。易于广泛应用于工况环境复杂的农用机械液压缓冲系统,其适用性相较于现有的缓冲系统具有很大的提高。 |
