Multifunctional filter valve for water treatment

Abstract

The invention belongs to the technical field of water treatment valve bodies, aims to solve the technical problem that in the prior art, the effective area of a water inlet and outlet hole in a valve body cannot concisely and effectively reach the effective area of a water inlet and outlet pipe opening outside the valve body, and provides a water treatment multifunctional filter valve which comprises a valve body, a movable valve plate, a fixed valve plate and a driving device. The fixed valve plate is fixedly installed in the valve body, the movable valve plate and the fixed valve plate are in running fit in the valve body, and a water inlet, a water outlet and a water outlet are formed in the side wall of the valve body. The multifunctional filter valve for water treatment has the advantages that the effective area of the water inlet and outlet hole in the valve body can be freely adjusted as required within the effective area range of the water inlet and outlet pipe orifice outside the valve body, the design limit of a single plane structure valve with the same function is achieved under the condition that auxiliary equipment is not added, and the multifunctional filter valve is simple in structure and convenient to use. The use cost and the production cost are reduced, the use efficiency is improved, and the performance is excellent.

Description

technical field [0001] The invention relates to the technical field of water treatment valve bodies, in particular to a water treatment multifunctional filter valve. Background technique [0002] In recent years, as more and more control valves with planar sealing structure are used in the field of water treatment, the market has recognized the structure of planar valves. The current industrial or civil water treatment systems mostly use the control valve body to switch the flow channel, and the control valve of the filtration system needs to realize functions such as filtration, backwashing, and positive flushing. The non-filtering processes such as backwashing and positive flushing of the filter system are collectively referred to as the flushing process. Existing water treatment filter valves mainly change the direction of water flow to realize the functions of running, backwashing, forward washing or simple running and backwashing. Filter valves are generally used in i...
