Drain Trap Check Valve Layout for Low-Maintenance Effluent Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drain traps require frequent maintenance to prevent corrosion, as they store effluent in multiple locations, leading to obstruction of effluent flow and increased maintenance needs.
Innovation Solution
A drain trap design where the storage unit communicates with the part under the normally-closed check valve, and the discharge unit is installed in the lowest part of the discharge-side communicating path, minimizing effluent storage and allowing proper flow, along with a modular construction for easy maintenance and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If effluent is stored in multiple locations including discharge-side storage unit, then effluent storage capacity is increased, but maintenance operations become more frequent and troublesome
Solution Approach 1:
The invention removes the discharge-side storage unit from the system. By extracting this component, the patent eliminates the problem of effluent accumulation in the discharge-side communicating path while maintaining adequate storage capacity through the storage unit that communicates with the part under the normally-closed check valve. This directly reduces maintenance frequency and trouble.
2Quantity of substance
If discharge-side storage unit is provided, then effluent storage capacity is increased, but effluent flow obstruction occurs
Solution Approach 1:
The invention extracts the discharge-side storage unit that was causing flow obstruction. The remaining storage unit is positioned to communicate with the part under the normally-closed check valve, ensuring that effluent flows smoothly to the discharge unit without accumulation in the discharge-side communicating path, thus maintaining productivity.
3Ease of operation
If storage unit communicates with part around check valve excluding area under valve, then check valve can float up, but effluent flow is obstructed when valve closes
Solution Approach 1:
The invention inverts the conventional storage unit positioning. Instead of storing effluent around the check valve excluding the area under the valve, the storage unit communicates with the part under the normally-closed check valve. This inversion allows the check valve to float up properly when effluent reaches a set amount, and effluent flows smoothly without obstruction when the valve closes, as the storage unit is positioned to facilitate rather than hinder flow.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies maintenance operations by reducing the need for frequent cleaning and corrosion prevention, ensuring efficient effluent flow and easy assembly/disassembly for maintenance.
Implementation Method 1
a normally-closed check valve which, being installed in the communicating path, floats up to allow the effluent in the storage unit to flow when the effluent reaches or exceeds a set amount
Data Source
AI summary
To provide a drain trap which can simplify maintenance operations by allowing effluent to flow to a discharge unit properly. The drain trap has a main body equipped with a communicating path which communicates a receiving unit and a discharge unit; a storage unit which, being installed in the communicating path, stores effluent received by the receiving unit; and a normally-closed check valve which, being installed in the communicating path, floats up to allow the effluent in the storage unit to flow to the discharge unit when the effluent reaches or exceeds a set amount, in which the storage unit is installed in such a way as to communicate with a part right under the normally-closed check valve, and the discharge unit is installed in the lowest part of a discharge-side communicating path so that no effluent will be stored in the discharge-side communicating path, which is that part of the communicating path which runs between the normally-closed check valve and the discharge unit.
