三用阀质量检测试验台的研制及修理质量控制

Development of the quality detection testbed of three-use valve and the repairing quality control

三用阀是单体液压支柱的重要组成部件,支柱的升柱、承载、卸载等功能都是通过三用阀来实现的。所以,三用阀修复质量的好坏直接影响到单体支柱的安全使用。陈四楼煤矿在生产实践过程中采用自行设计的三用阀质量检测试验台,并形成了一系列控制三用阀修理质量的措施。

Three -use valve is an important component of the monomer hydraulic pillar, the rising, loading, unloadingand other functions of pillar are realized through the three - use valve. So, the repairing quality of the three - use valvedirectly affects the safe use of single prop. Chen silou coal used the quality detection testbed of three - use valve whichdesigned by ourselves in the production process, and formed a series of measures of repairing quality of three - usevalve, obtained a good application effect.
