Filtering valve for switch of water pool

Abstract

The invention provides a filtering valve for a switch of a water pool. The filtering valve comprises a buoy, a rotating disc, an end cover, a filtering valve body and a pressing sleeve, wherein a rotating rod is fixed at the front part of the buoy through a screw and connected with the rotating disc in a penetrating manner; the rotating disc is embedded in the end cover; the end cover is designedto be equipped with a gear shaft; an elastic ring is designed to be mounted at the front end of the gear shaft; a gear disc is connected with the rear part of the elastic ring; a hollow driving shaftis mounted at the middle of the filtering valve body; the hollow driving shaft and the filtering valve body are connected through a sphere; the pressing sleeve is connected with the filtering valve body; the hollow driving shaft penetrates through the pressing sleeve; a connecting disc is designed to be mounted at the front end of the pressing sleeve; and an isolating ring is designed to be mounted between the pressing sleeve and the end cover.

Description

technical field [0001] The invention relates to the technical field of pool storage and reservoirs, in particular to a pool switch filter valve. Background technique [0002] Filters are widely used in surface water purification, side-flow filtration of circulating water, removal of suspended impurities in production wastewater, and filtration of organic sewage after biochemical and secondary sedimentation treatment. The steel valveless filter mainly uses the siphon principle for regular backwashing. The filter does not use valves for water inflow and outflow, flushing and drainage, and operates automatically by hydraulic action. The filter valves on the market are driven by motor principles, and the design is often very complicated. As a result, the manufacturing cost of the valve body is high. If the water body is blocked by debris, the water cannot be filtered when the water body is filtered, and frequent maintenance is required. Contents of the invention [0003] ...

The steel valveless filter mainly uses the siphon principle for regular backwashing. The filter does not use valves for water inflow and outflow, flushing and drainage, and operates automatically by hydraulic action. The filter valves on the market are driven by motor principles, and the design is often very complicated. This leads to high production costs of the valve body. If the water body is blocked by debris, the water cannot be filtered during the water body filtration, and frequent maintenance is required.
