Mixing Valve Seat Access Through Connection Channel Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating or cooling installation control valves require complete separation from connecting conduits for maintenance and replacement of valve seats, making the process cumbersome and inconvenient.
Innovation Solution
The control valve design includes assembly openings in the connection channels, allowing sealing elements to be inserted and removed without disassembling the valve element or separating the connection conduits, enabling easy maintenance and replacement without disrupting the fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sealing elements are inserted through the valve space or connection channels, then the valve can be assembled, but the complete valve unit must be separated from connecting conduits for maintenance and replacement
Solution Approach 1:
The connection channel is divided into two sections: a first section extending from the valve space to an assembly opening, and a second section extending from the first section to the second end. This segmentation allows the sealing element to be accessed and replaced through the assembly opening without requiring separation of the valve from connecting conduits, thus resolving the contradiction between ease of manufacture and ease of repair
2Ease of repair
If sealing elements are inserted through the assembly opening, then maintenance is simplified, but the connection channel structure becomes more complex
Solution Approach 1:
The assembly opening serves as an intermediary access point that enables maintenance of sealing elements without requiring complete disassembly. The first channel section acts as an intermediary pathway connecting the assembly opening to the valve space, allowing sealing element replacement while maintaining a relatively simple overall structure

AI summary
A heating or cooling installation control valve includes a movable valve element which is arranged in a valve space (8), as well as at least two connection channels (24, 26) which each have a first end in fluidic connection with the valve space (8) and have an opposite second end (A, B) for connection to a fluid-leading component. A sealing element (18) is arranged in at least one of the connection channels (24, 26) at a first end thereof. The sealing element is in contact with the valve element (6). The at least one connection channel (24, 26), in which the sealing element (18) is arranged, in addition to the second end (A, B), includes an assembly opening, through which the sealing element (18) can be inserted into the connection channel (24) and removed from of the connection channel (24).
