Multifunctional water treatment valve

Abstract

The invention aims to provide a multifunctional water treatment valve, which comprises a valve body, a valve cover, a valve element and a shifting fork; the valve cover is fixedly installed on the valve body; the valve element is arranged in the valve body; the valve body is provided with a water inlet pipe, a water outlet pipe, a water drainage pipe and a jet device; the bottom of the valve body is provided with an outer filter element connector and an inner filter element connector which are connected with a filter element; a valve cavity is arranged in the valve body; the valve element comprises a fixed piece and a movable piece; the fixed piece is fixedly installed on the valve body; the movable piece is in linkage with the shifting fork and coaxially rotates relative to the fixed piece in a sealed mode; a drainage hole communicated with the water drainage pipe is arranged at the center of the fixed piece; a filter element liquid inlet hole communicated with the outer part of the filter element, a water inlet hole communicated with the water inlet pipe, a filter element liquid outlet hole communicated with the inner part of the filter element, a jet flow outlet hole communicated with the liquid outlet end of the jet device and a jet flow inlet hole communicated with the liquid inlet end of the jet device are anticlockwise arranged in the circumferential direction of the fixed piece; and a central blind hole which extends in a fan shape from the circle center to the radial direction is arranged at the central position of the shifting fork.

Description

technical field [0001] The invention relates to the field of valves, in particular to a multifunctional water treatment valve. Background technique [0002] In daily life, domestic water contains many inorganic salts, such as calcium and magnesium salts. These salts cannot be found by naked eyes in water at normal temperature. Once they are heated and boiled, a lot of calcium and magnesium salts will precipitate out in the form of carbonate, and they will cling to the walls of the pot to form scale. Some water with high content of calcium and magnesium ions does not have scale formation. This is because these calcium and magnesium ions exist in the form of chloride salts, which are soluble, so they cannot be precipitated when heated. [0003] The content of calcium and magnesium ions in water is usually expressed by the "hardness" index. 1 degree of hardness is equivalent to 10 mg of calcium oxide per liter of water. Water below 8 degrees is called soft water, above 17 de...

Problems solved by technology

In the prior art, most water treatment valves have a flat sealing structure, but there are certain defects in the structural rationality and durability of the sealing sheet
