And in order to intercept larger particle impurities in the water, a filter needs to be installed additionally. By adopting this method to reduce the water flow rate and filter impurities in the water, the filter is an indispensable device on the pipeline of the conveying medium. It is usually installed on a pressure reducing valve, a pressure relief valve, and a constant water level valve. Through a water distribution device, the water flow can be prevented from directly impacting the filter screen and the interior of the filter, preventing damage to the filter screen and the inner wall, ensuring the use effect and service life of the filter, and being safe and practical.
