Abstract

A turn-over plate type filter pool is composed of pool body, filtering tubes, water collecting chamber, water draining pipe, back flushing pipe, filtering material layer, the canal and overflow dam for draining the black flushing water, and the flap valve consisting of valve frame, flap, sealing rubber ring and drive mechanism which comprises drive cylinder and push-pull connecting rod.

Description

(1) Technical field [0001] The invention relates to a valve in a water treatment filter and a water treatment filter equipped with the valve. (2) Background technology [0002] Existing filters include siphon filters, ordinary fast filters, double valve filters, mobile cover filters, V-shaped filters and flap filters. There is a filter tube in the lower part of the flap filter, and a water collection chamber at the bottom of the pond, which is connected with the filtered water outlet pipe. There is a filter material layer in the filter tank, and there is a reversed connection with the outside of the filter material layer. Flush the drainage channel, and install a flap valve at the hole connecting the filter tank and the recoil drainage channel. The existing flap valve comprises a valve frame fixed on the opening, a valve plate hinged with the valve frame and a drive mechanism hinged with the valve plate. Although the recoil system, drainage system and filter material selec...
