Venturi Steam Trap Drainage Adjustment and Strainer Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nozzle-type steam traps face challenges in adjusting to changes in condensate discharge due to variations in steam usage and pressure, and they suffer from rigidity issues with microstructured screens, making maintenance and filter replacement difficult.
Innovation Solution
A drainage volume adjusting mechanism that allows for variable height differences between drain and non-drain vents using a rotational mechanism, and a strainer filter with a support body to enhance rigidity and ease of maintenance, such as using a spring material or heat-resistant fiber for the screen and support body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-height piping structure is used in nozzle-type steam traps, then the structure is simple and manufacturing is easy, but the condensate discharge volume cannot be adjusted when steam usage and pressure vary
Solution Approach 1:
The piping structure incorporates a rotatable component that allows the height difference between the drain vent and non-drain vent to be dynamically adjusted. This rotational mechanism enables the steam trap to adapt to varying condensate discharge requirements by changing the vertical positioning of the vents, transforming a static structure into a dynamic one that can respond to different operating conditions.
2Manufacturing precision
If microstructured screens are used in strainers, then filtration precision is improved, but the screen rigidity deteriorates making maintenance difficult
Solution Approach 1:
The strainer employs a composite structure combining a microstructured screen with a support body. The support body, made of spring material or heat-resistant fiber, provides the necessary rigidity and structural strength, while the microstructured screen maintains its high filtration precision. This composite design allows the delicate microstructured screen to function effectively without being damaged during installation, operation, or maintenance.
3Manufacturing precision
If microstructured screens are used in strainers, then filtration precision is improved, but ease of repair and maintenance deteriorates
Solution Approach 1:
The strainer is divided into separable components: the microstructured screen is detached from the support body, allowing the screen to be independently removed and replaced. This segmentation enables maintenance personnel to easily access and replace the filtration screen without disassembling the entire strainer structure, significantly improving ease of repair while maintaining high filtration precision through the microstructured design.

Implementation Method 2
a piping structure in which the height difference between a drain vent through which condensate is discharged into a drain reservoir disposed in the steam trap and a non-drain vent through which condensate is discharged from the drain reservoir to the outer side of a steam trap can be varied by means of a rotational mechanism
