Embodiment Construction

[0078] The technical solution of the present invention will be explained more clearly and completely through the description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0079] Such as figure 1 , figure 2 ,as well as Figure 6 As shown, the waterway switching valve of the preferred embodiment of the present invention includes a valve body 1 . The valve body 1 includes a hollow cylindrical casing 10 . The housing 10 has a housing hollow cylindrical portion 103 , and a housing first end portion 101 and a housing second end portion located at opposite ends of the housing hollow cylindrical portion 103 .

[0080] Such as figure 1 What is shown is a structural schematic view of the waterway switching valve viewed from the side of the valve body 1 that is suitable for connecting with the filter. The valve body 1 also includes: a valve body first interface 15 and a valve body second interface 16 provided on the first end por...

Abstract

The invention provides a water way switching valve. The valve comprises a hollow valve body, a valve element rotor, a valve body water inlet and two valve body drainage outlets, wherein the valve element rotor is rotationally installed in a shell around the center line X, the valve body water inlet is communicated with external water, the two valve body drainage outlets are formed in the peripheral direction of the valve body, two valve body connectors connected with a water filter water way are arranged on one side of the valve body, then, a wading opening corresponding to the valve body is formed in the valve element exquisitely, the position of the valve element is switched inside the valve body, and forward and reverse switching of the water flow direction in the water way switching valve is achieved. In the water way switching process, position replacement or external water flow direction control does not need to be performed on the external water flow connectors. Accordingly, thewater way switching valve can greatly simplify work of operators and maintainers, the requirement for the operators and a matched control system is lowered, and the water way switching valve is suitable for higher-degree automatic control. The invention further provides an electric water way switching valve, a position calibration method thereof, a backwashing control method and a filter controlmethod.

Description

technical field [0001] The invention relates to a multi-position valve for switching waterways, in particular to a multi-position valve for realizing forward and reverse switching of fluid flow, a multi-position electric valve, and a corresponding calibration method, backwash control method, and filtration control method for the valve. Background technique [0002] Water is an indispensable natural resource for human development and the material basis for the survival of human beings and all living things. In today's world, the water crisis caused by insufficient water resources and pollution has become a complex problem faced by any country in terms of policy, economy and technology, and the main restrictive factor of social and economic development. To solve the water problems closely related to human social life in reality, modern water treatment technology and water treatment filters must be used. [0003] At present, the most common in daily life is a small household w...
