The utility model relates to a double speed water cap, which comprises a water cap seat, a water cap cover plate, a trapezoid sieve tube, a diversion pipe, a flow valve cup and a flow valve core. A water cap, a water cap cover plate and a trapezoidal sieve tube are composed of a medium cavity body. The flow valve cup is arranged in the middle cavity, and the upper end of the flow guide pipe is extended into the flow valve cup, the water cap seat, and the ladder. The shape sieve tube, the water cap plate and the diversion pipe are connected through the bolts at the top of the diversion pipe. The flow valve core is located in the flow valve cup and is slid on the screw. The bottom of the flow valve core is convex with a horn type baffle and the baffle encircling the diversion pipe into the tube wall in the flow valve cup. The double flow speed filter cap provided by the utility model can greatly increase the force produced by the anti flushing water on the flow valve core, make the flow valve core float up and down more smoothly, the working stability is better, the reaction speed is faster, and the service life of the product is prolonged.

一种双流速滤水帽
本技术涉及水处理设备
,具体说是一种双流速滤水帽。
技术介绍
滤水帽主要应用于水处理设备中,分布安装在滤料层的多层孔板上。工作时,处理水自上而下经过滤料层,再通过滤水帽流出。经过多次过滤后,要对滤料层进行反冲洗,使滤料层畅通或恢复活性,此时水流自下而上,经过滤水帽喷出,对滤料层进行反冲洗。专利号为CN1628890A的中国专利技术专利公开了一种双流速滤水帽,该滤水帽通过在伸入进水腔室(由水帽头和水帽座围合而成)内的导流管上罩设一个通流阀杯,利用通流阀杯的水流通量变化来调节导流管的水流通量,同时在通流阀杯内设置一个通流阀芯,利用通流阀芯的上下浮动来自动调节通流阀杯的水流通量,从而实现反冲洗流速大于过滤水流速的目的,达到更好的反冲洗效果。按照上述专利的方案设计,通流阀芯在过滤水时依靠自身的重力回落至导流管的顶部,而在反冲洗时,反冲水对通流阀芯产生的冲击力要足以克服通流阀芯的重力以及通流阀芯与螺杆之间的摩擦力,如此才能将通流阀芯向上顶起。但是,由于通流阀芯的底面与导流管的侧面是相互垂直的,反冲水从导流管侧面的通水孔喷出时无法直接喷射到通流阀芯上, ...
