Overflow Pipe Flow Regulator for Adjustable Drain Valve Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain valves in toilets lack the ability to regulate drainage speed, requiring users to replace entire models to adjust flow rates, which is inefficient and costly.
Innovation Solution
A drain valve with a flow rate regulator at the lower end of the overflow pipe, allowing for controlled water flow through a defined channel, enabling adjustment by replacing only the flow rate regulator without replacing the entire valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the drainage speed of the drain valve is fast, then the flushing effect is good, but the user cannot regulate the drainage speed
Solution Approach 1:
The drain valve is divided into a fixed valve body and a replaceable flow rate regulator assembly. The flow rate regulator can be separated from the valve body and replaced with different models to adjust drainage speed, allowing users to regulate flow rate without replacing the entire valve.
Solution Approach 2:
The system transitions from a static, fixed drainage configuration to a dynamic, adjustable configuration. Users can change the flow rate regulator to different models depending on their flushing needs, making the drainage speed adaptable rather than fixed.
2Adaptability or versatility
If the user needs to regulate the drainage speed, then the flushing performance can be adjusted, but the user needs to replace different models of drain valves
Solution Approach 1:
The drain valve is segmented into a permanent valve body and a replaceable flow rate regulator. This allows users to change only the regulator component rather than replacing the entire valve assembly, reducing costs and simplifying the adjustment process.
Solution Approach 2:
The flow rate regulator is extracted as a separate, interchangeable component from the valve body. Users can remove the existing regulator and install a different model to adjust drainage speed, eliminating the need to replace the entire valve.
3Adaptability or versatility
If a flow rate regulator is added to the overflow pipe, then the drainage speed can be controlled, but the device complexity increases
Solution Approach 1:
The flow rate regulator is designed as a separate component that attaches to the overflow pipe, keeping the overall structure modular. This segmentation allows the regulator to be added without significantly complicating the base valve design.
Solution Approach 2:
The flow rate regulator serves multiple functions: it controls drainage speed, can be replaced with different models for different flow rates, and attaches to the existing overflow pipe structure. This multi-functionality justifies the added complexity by providing versatile control capability.

AI summary
The present application discloses a drain valve, comprising a valve body (1), a valve seat (2) and an overflow pipe (3). The valve seat includes a drainage channel (21). The overflow pipe includes a blocking element (4) and a flow rate regulator (5). When the overflow pipe is in a raised state, the blocking element leaves a channel water inlet (211), the flow rate regulator is partially or completely located above the channel water inlet, and a water flow channel (20) is formed between the flow rate regulator and the channel water inlet. An amount of water entering the drainage channel from the channel water inlet in unit time can be defined by the flow rate regulator, and thus a drainage flow rate can be controlled. If a user needs to change the drainage flow rate, the user only replaces different types of flow rate regulators, without replacing the whole drain valve to save costs.
