The utility model relates to a double speed water cap, including a water cap seat, a water cap plate, a trapezoid sieve tube with a bar, a flow guide tube, a flow valve cup, a flow valve core, a ceramic sleeve and a rubber ring. 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 guide pipe is on top. In the flow valve cup, the water cap, the trapezoid sieve tube, the water cap cover plate, and the guide pipe are connected through the bolts at the top of the diversion pipe. The ceramic sleeve is located in the flow valve cup and is set on the screw bolt. The rubber ring is located between the ceramic sleeve and the bottom of the flow valve cup and is set on the screw screw screw, and the rubber ring is set. The outer diameter is larger than the outer diameter of the ceramic bushing, and the through flow spool is positioned in the through flow valve cup and the sliding sleeve is arranged on the ceramic sleeve. The double flow speed filter cap provided by the utility model can effectively solve the problem of stagnation of the flow valve core, good working stability, easy production and assembly, and the overall structure has high strength and long service life.

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。为了达到较好的反冲洗效果,反冲洗时的水流速度要比正常过滤时的水流速度快很多,而传统的滤水帽无法实现反冲洗流速与过滤水流速的自动调节。因此,有必要研发一种可自动调节不同工作状态下水流速度的双流速滤水帽。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,从而实现在不同工作状态下水流速度自动调节的目的。但这种双流速滤水帽仍存在一个问题,使用时间长后通流阀芯容易发生卡滞,主要是因为金属螺杆在时间长后表面会生锈或沉积水垢,使得通流 ...
