煤矿液压支架用手动换向阀试验装置的研制及应用

Developing and Applying Experimental Installation for Hand-operated Direction Valve of Hydraulic Support

针对目前矿用液压支架手动换向阀耐久性试验中存在的一些问题,研制了液压支架用手动换向阀试验装置。该试验装置使手动换向阀的各项型式试验实现自动化,使用方便、快捷,提高了手动换向阀的试验效率,也减少了试验人员的劳动强度,对于提高换向阀的质量提供了有效保障。

The experimental installation for hand-operated direction valve of hydraulic support was developed address the existing problems in life test for hand-operated direction valve. All the tests for direction valve were automation using the experimental installation, and it is easy、 convenient and speedy to operate. The test efficiency is greatly raised and the physical labor intensity of researchers is far less than before with using the experimental installation. All those are providing strength for improving the quality of the hand-operated direction valve.
