Abstract

The invention discloses a multifunctional control valve, which comprises a valve body, a cap, a valve rod, a fixed valve plate and a movable valve plate, the fixed valve plate and the movable valve plate are arranged in the valve body, and adopt end face rotary seal, the movable valve plate is connected with the valve rod, the control valve is provided with a raw water inlet, a clean water outlet, a drain connector, a first filter element connector and a second filter element connector, and the fixed valve plate is provided with a first filter element connector passage, a second filter element connector passage, a fifth through hole and a sixth through hole; in the control valve, the first filter element connector passage communicates with the first filter element connector, the second filter element connector passage communicates with the second filter element connector, the fifth through hole communicates with the clean water outlet, and the sixth through hole communicates with the drain connector; and the movable valve plate is provided with a water inlet passage which communicates with the raw water inlet, and is also provided with a communicating blind hole. The multifunctional control valve has the advantages that: the flow passage in the valve body is enlarged, so that water flow is enlarged, and raw water can be supplied during backward washing and forward washing.

Description

technical field [0001] The invention relates to a multifunctional control valve for water treatment system. Background technique [0002] In the existing industrial or domestic water treatment technology, multifunctional control valves are often used to realize functions such as filtering, backwashing, and positive washing of the filter element. In recent years, planar multi-function control valves have increasingly become one of the mainstream valve types of multi-function control valves. First of all, due to the complexity of the design of the planar valve plate and internal flow channel and the limitation of the area of ​​the valve plate, it is difficult to design a planar valve with a large channel; , Supply untreated raw water while washing, the existing planar multifunctional control valve has been difficult to meet this demand. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present inventi...
