Distributor Valve Magnetic Drive for Drift-Free Flow Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distributor valves with integrated flow measuring devices require operator tact and precision for flow rate adjustment, which can be imprecise and costly in terms of production and maintenance, due to manual drive limitations and imprecise setting elements.
Innovation Solution
A distributor valve design featuring a rotating sight glass with a regulating insert and adjustable stop, secured by a locking cap, allows for precise and reproducible adjustment of the flow rate through different adjustment paths, simplifying axial adjustment and locking of valve components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual drive with adjustable sleeves is used for flow rate adjustment, then the valve can be operated manually, but the setting precision is insufficient and components can move unintentionally
Solution Approach 1:
The patent replaces the traditional mechanical handwheel with a magnetic drive system. The magnetic coupling transmits rotational force from the outer periphery to the valve element internally, eliminating the need for mechanical connections that can move or loosen. This substitution provides precise, drift-free setting while maintaining easy manual operation through the handwheel interface.
2Adaptability or versatility
If axially adjustable sleeves with stops are provided for closing limitation, then end positions can be set, but the setting elements can move when the hand wheel is actuated
Solution Approach 1:
The patent eliminates mechanical connection elements between the handwheel and valve element by using magnetic coupling. The magnetic field transmits torque without physical contact, preventing any movement or displacement of setting elements during operation. This ensures stable, drift-free positioning while maintaining the ability to set end positions.
3Manufacturing precision
If precision adjustment mechanism is implemented, then flow rate can be precisely regulated, but production costs and maintenance effort increase
Solution Approach 1:
The patent uses a magnetic drive system that provides precise control through magnetic coupling strength and direction. This eliminates complex mechanical precision mechanisms while achieving accurate flow rate regulation. The magnetic system is simpler in construction, reducing production costs and maintenance requirements compared to traditional precision mechanical adjustment mechanisms.

AI summary
The invention relates to a distributor valve (1) with an integrated flow measuring device for use on a pipe, in particular for hot water and heating systems, with which, through simplified axial adjustment and locking of the components of the valve body with regard to a flow rate, better operation of the distributor valve combined with more precise adjustment of the flow rate is obtained, the flow rate being adjusted by rotating a sight glass (3) and thus adjusting a regulating insert (7) arranged at a lower end of the sight glass, with different adjustment paths of the regulating insert being achieved by an adjustable stop by means of a setting element (16) are provided, which is adjustable in height and held securely in a predetermined position, thereby limiting the flow.
