Delayed Closing Valve Instant Flow Interruption Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-closing valves with delay chambers do not allow users to interrupt water flow instantaneously, limiting user control, especially in applications like shower installations where immediate water cessation is desired for tasks like soaping.
Innovation Solution
A second push-button valve is connected between the water inlet and the delay chamber of the main valve, allowing users to briefly apply network pressure to stop the water flow by pressing the second valve's pusher, which is designed to push the piston back against its seat, interrupting the flow, and can be resumed by actuating the primary push-button valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a delay chamber with calibrated orifice is used to control water flow timing, then automatic timing control is achieved, but user ability to interrupt flow instantaneously is lost
Solution Approach 1:
A second push-button valve is introduced as an intermediary device between the water supply and the delay chamber. This intermediate valve allows users to quickly release pressure from the delay chamber, enabling instantaneous interruption of water flow without disrupting the automatic timing mechanism's overall function.
2Ease of operation
If the delay chamber is vented to open air via a push-button valve, then remote control capability is achieved, but instantaneous flow interruption is not possible
Solution Approach 1:
The system utilizes pneumatic principles by controlling water flow through pressure management in the delay chamber. The second push-button valve enables rapid hydraulic pressure equalization by venting the delay chamber to atmosphere, causing instantaneous flow interruption through pressure-driven piston movement rather than gradual draining.
3Ease of manufacture
If the main faucet time delay is fixed at factory setting, then manufacturing simplicity is maintained, but user adaptability is reduced
Solution Approach 1:
The second push-button valve empowers users to self-adjust the system's behavior in real-time without requiring factory reconfiguration or technical expertise. Users can independently control flow interruption timing by operating the additional valve, providing adaptability while maintaining the simplicity of the original fixed-time design.

Implementation Method 1
by a brief action on the push button of this tap, all the pressure of the network is applied to the piston of the main tap which is strongly pushed back against its seat
Implementation Method 2
the pressure of the network is applied to the piston of the main tap which is strongly pushed back against its seat
Implementation Method 3
a delay chamber in which a piston connected in translation to the valve valve can move, said chamber communicating with the water inlet via a calibrated orifice
