RTD滑道滚球式止回阀
RTD slide roller ball check valve

概述
RTD滑道滚球式止回阀,采用橡胶包皮滚球为阀瓣,在介质的作用下,可在阀体内的整体式滑道上作上下滚动,从而打开或关闭阀门,密封性能好,消声式关闭,不产生水锤。阀体采用全水流通道,流量大,阻力小,水头损失比旋启式小50%,水平或垂直安装均可,可用于冷水、热水、工业及生活污水管网,更适合潜水排污泵,介质温度为0~80℃。
Overview
RTD slide roller ball check valve, using rubber coated roller ball as the valve disc, under the action of the medium, can be rolled up and down the integral slide in the body, so as to open or close the valve, good sealing performance, silent closure, no water hammer. The valve body adopts full flow channel, large flow rate, small resistance, head loss is 50% less than the swing type, horizontal or vertical installation can be used for cold water, hot water, industrial and domestic sewage pipe network, more suitable for diving sewage pump, medium temperature is 0~80℃.
