我厂生产的ZFS—L20H_2—Y※M—T型串联油路多路换向阀,是由进油阀片、出油阀片和若干中片组合而成。为进一步提高产品质量,就必须不断地发现问题,不断地解决问题。多路阀明显的片间外漏是基本解决了,但通过仔细检查,却发现多路阀在进行换向冲击时,片间有一点一点的微渗现象。这是什么原因产生的呢?原来多路阀进行换向冲击时,双头螺栓承受周期性的拉力载荷。升压时,双头螺栓受拉伸;降压时,
ZFS-L20H_2-Y ※ M-T series oil circuit multi-way valve produced by our factory is composed of oil inlet valve piece, oil outlet valve piece and several medium pieces. In order to further improve product quality, we must constantly find problems and constantly solve the problems. Significant multi-channel valve leakage between the film is basically solved, but through careful examination, but found that the multi-way valve in the commutation impact, a little bit of micro-osmotic membrane between the phenomenon. What is the reason for this? The original multi-way valve commutation impact, the studs to withstand periodic tensile load. Boost, the stud by tension; buck,
