Ultrafiltration flow rate timed automatic mechanical flushing valve device

Abstract

The invention discloses an ultrafiltration flow rate timed automatic mechanical flushing valve device, which comprises a mechanical flushing valve arranged on an ultrafiltration membrane flushing water pipeline, wherein the tail end of a valve rod of the mechanical flushing valve is fixedly connected with a driving device, the driving device is arranged and assembled in an ultrafiltration membrane clean water outlet pipeline, the driving device drives the valve rod to rotate through the impact mechanical rotation via water flow flowing in the ultrafiltration membrane clean water outlet pipeline, the mechanical flushing valve is provided with a mechanical flushing valve diaphragm group sheathed and matched with the valve rod, the mechanical flushing valve diaphragm group is respectively provided with an upper flushing water guide hole, a lower flushing water guide hole and a middle connecting passage, the middle connecting passage is used for communicating the upper flushing water guide hole and the lower flushing water guide hole, and the driving device drives the middle connecting passage to do circumferential rotation through the valve rod under the impact effect of the water flow to realize the periodic on-off states of the upper flushing water guide hole and the lower flushing water guide hole, so the on-off state of the ultrafiltration membrane flushing water pipeline is controlled, and the timed flushing opening and closing function of the flow rate type mechanical transmission is realized.

Description

technical field [0001] The invention relates to water purification equipment, in particular to a device for flushing filter cores of ultrafiltration equipment, in particular to an automatic mechanical flushing valve device for ultrafiltration flow timing. Background technique [0002] Ultrafiltration water purification equipment is generally used for a period of time, because impurities, viruses and other harmful substances in the raw water are intercepted and adsorbed by the filter element, which easily leads to the blockage of the filter element. Blockage of the filter element will result in reduced flow or functional failure of the filter element. At present, the protection of the filter element adopts regular filter element flushing. In the prior art, the filter element flushing is manually controlled flushing or regularly controlled flushing by an electrical control system. Manual flushing is cumbersome and troublesome. Many times people will forget or do not flush for...

AI Technical Summary

Problems solved by technology

Manual flushing is cumbersome and troublesome. Many times people will forget or do not flush for a long time. However, the electrical control system needs to add additional circuit control and additional power supply to control timing flushing, which increases the risk of electric shock and people's use costs. Both methods have certain advantages. Defects, unable to meet the diverse needs of the market
