德国奥莱斯OLES进口不锈钢刀形闸阀
【进口不锈钢刀形闸阀】特点：
本阀门为双闸板单面密封设计，有效防止阀腔内因*积灰而造成的阀门开关不到位、卡瑟等现象。阀体采用精密铸钢件，密封填料采用耐磨耐高温氟橡胶密封组件，阀板与阀座间密封面采用耐磨硬质合金材料或耐磨增韧结构陶瓷，表面光滑，硬度可达60~70HRC，解决了密封面因物料冲刷而易被冲蚀、寿命不高的问题，使用寿命比普通材料阀门长5-10倍，为用户带来理想的使用效果和经济效益，大大提高了设备运行的安全性、稳定性。本阀具有密封性能好、耐磨性强、耐高温、启动负荷小、无卡灰或积灰现象、使用寿命长等特点。
The valve is designed for single-side sealing with double gate, which can effectively prevent the valve opening from not in place and Cather caused by long-term ash accumulation in the valve chamber. The valve body is made of precise cast steel, the sealing filler is made of wear resistant and high temperature resistant fluororubber sealing assemblies, and the sealing surface between the valve plate and the seat is made of wear resistant cemented carbide or wear resistant and toughened structural ceramics. The surface is smooth and the hardness can reach 60~70HRC. The problem that the sealing surface is easy to be eroded due to material erosion and the service life is not high is solved. Compared with ordinary material valves, the valve is 5-10 times longer, which brings ideal use effect and economic benefits to users, and greatly improves the safety and stability of equipment operation. The valve has the characteristics of good sealing performance, strong wear resistance, high temperature resistance, small start-up load, no stuck or accumulated ash, long service life, etc.
【进口不锈钢刀形闸阀】工作原理:
当气源从上进气口通入时，阀杆带动阀板向下运动，阀门关闭。当气源从下进气口通入时，阀杆带动阀板向上运动，阀门开启。阀板与阀座之间加载弹簧，弹簧弹力始终使阀板压向阀座保证阀门的密封性，又容许阀板在垂直上下方向移动，这有助于补偿阀门零件的热胀冷缩，并能克服任何背压变化对密封的影响与防止颗粒介质进入两密封面之间。在启闭过程中，阀板能产生自转，使得密封面之间产生研磨、抛光作用，而且由于阀体对通道偏心，在开启排卸物料时，会产生涡流，形成的物料旋涡会自行清扫阀门内腔。此阀门为双闸板单面密封，*的下阀体斜面加镂空下阀板设计，保证阀门内腔不积灰。所有的这些特点，使得这种阀门具有超长的使用寿命，为您的系统安全运行提供了可靠的保证。
【进口不锈钢刀形闸阀】应用：
本阀门主要用于火力发电企业的粉煤灰气力输送系统中，做仓泵进料阀、平衡阀、透气阀、排气阀、排堵阀，也可用作卸灰阀。同时也可适用于水泥、矿山、造纸、化工等各类有磨损的干粉尘、水、蒸汽等介质在管道上作启闭之用。
