Float Type Drain Trap Segmented Blow Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional float type drain traps allow a significant amount of foreign material to flow downward toward the outlet during condensate recovery, contaminating the reused condensate.
Innovation Solution
Incorporating a blow passage that communicates with the periphery posterior to the valve member of the operation member, allowing removed foreign material to be blown outside instead of flowing toward the outlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the operation member is advanced to clean foreign material from the discharge passage, then cleaning effectiveness is improved, but foreign material flows downward toward the outlet contaminating recovered condensate
Solution Approach 1:
The discharge passage is segmented into two separate exit paths: a blow passage for foreign material and an outlet for cleaned condensate. This segmentation allows foreign material removed during operation member advancement to be directed through the blow passage away from the outlet, preventing contamination while maintaining cleaning effectiveness
Solution Approach 2:
The blow passage acts as an intermediary pathway that intercepts and redirects foreign material before it can reach the outlet. By providing this intermediate escape route, the system prevents harmful foreign material from mixing with recovered condensate while the operation member continues its cleaning function
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
Prevents a large amount of foreign material from reaching the outlet, ensuring cleaner condensate recovery by effectively diverting it away from the discharge path.
Implementation Method 1
a float type drain trap that automatically discharges the condensate generated in steam, compressed air, and a gas piping system by floatation and drop of a float
Implementation Method 2
removed foreign material can be blown outside from the blow passage

AI summary
A body 1 and a cover 2 form a valve casing. An inlet 5, a valve chamber 4, and an outlet 7 are formed in the valve casing. A valve seat member 9 is attached to the lower portion of the valve chamber 4. A discharge passage 8 that communicates the valve chamber 4 with the outlet 7 is formed to the valve seat member 9. A float 11 that is moved away from and seated on the valve seat member 9 to open and close the discharge passage 8 is disposed in the valve chamber 4. An operation member 14 whose tip end is disposed in the discharge passage 8 is provided to be externally operable in the forward and backward directions. A valve member 16 that communicates between the periphery anterior to and the periphery posterior to the middle portion of the operation member 14 when the operation member 14 is in the advanced position and that blocks the periphery anterior to and the periphery posterior to the middle portion of the operation member 14 from one another when the operation member 14 is in the most retracted position is provided to the middle portion of the operation member 14. A blow passage 17 is formed to communicate the periphery posterior to the valve member 16 of the operation member 14 with the outside distinct from the outlet 7.
