Socket Structure With Slidable Sleeve For Fluid Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing socket structures for handling fluids that tend to adhere and solidify, such as slurry-like chemical solutions, face issues with obstruction of the attachment/detachment and sealing functions due to solid deposits forming on valve and ball lock mechanisms, making the process difficult and unreliable.
Innovation Solution
A socket structure with a slidable and rotatable sleeve that screws into a thread portion on the vessel side, ensuring that any liquid remaining in the socket falls back into the vessel upon detachment, preventing adherence to the joint and allowing for easy and reliable attachment/detachment, with features like a screwing completion indicator and tapered surface for improved handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a socket structure with valve mechanism and ball lock mechanism is used for handling slurry-like chemical solutions, then the sealing function and attachment/detachment capability are improved, but solid deposits form on the mechanisms obstructing their movement and sealing function
Solution Approach 1:
The socket structure is divided into separate functional components: a valve mechanism for sealing control and a ball lock mechanism for attachment/detachment. By segmenting these functions into distinct mechanisms, each can be optimized independently to prevent solid deposit accumulation while maintaining their respective functions.
Solution Approach 2:
The ball lock mechanism uses balls that roll along a groove rather than traditional threading or clamping mechanisms. This inverted approach to locking prevents solid deposits from obstructing the locking action, as the rolling balls can navigate through the groove even with some deposit accumulation.
2Reliability
If a valve mechanism with sliding cylinder and bellows is used, then leakage prevention is improved, but solid deposits obstruct the smooth movement of the valve mechanism
Solution Approach 1:
The valve mechanism incorporates bellows made of flexible material that can deform to seal around the sliding cylinder. This flexible sealing approach maintains reliable leakage prevention while accommodating the movement of the sliding cylinder, as the bellows can expand and contract during valve operation without being obstructed by solid deposits.
Solution Approach 2:
The valve mechanism uses a sliding cylinder that moves dynamically within the bellows rather than a fixed sealing structure. This dynamic design allows the valve to open and close smoothly while the bellows flex to maintain the seal, preventing solid deposits from permanently obstructing the sealing function.
3Strength
If liquid remaining in the socket drips on the joint during detachment, then the joint is formed, but solid deposits form on the thread portion obstructing smooth screwing
Solution Approach 1:
The socket is designed with a drainage feature that allows remaining liquid to drain back into the vessel before the attachment/detachment operation is performed. This preliminary draining action prevents liquid from dripping onto the thread portion during screwing, eliminating the cause of solid deposit formation that would obstruct future screwing operations.
Solution Approach 2:
The design extracts or removes the harmful element (remaining liquid) from the attachment area by providing a drainage path back to the vessel. This extraction of liquid before the screwing operation prevents solid deposits from forming on the thread portion, maintaining smooth screwing capability while still forming a strong joint.

AI summary
Provided is a socket structure capable of preventing or inhibiting defective attachment/detachment thereof and defective movement and defective sealing of a valve mechanism due to a solid deposit caused by a fluid. A socket used by connecting the socket to a plug of a connector includes a socket body in which a channel is formed and which has a valve mechanism; and a sleeve which is disposed so as to be slidable in an axial direction thereof and rotatable along an outer circumferential surface of the socket body. The socket is configured to be screwed and secured by inserting and connecting an entrance of the channel that opens at a lower end of the socket body to a plug exit that opens at an upper end of the plug and then a sleeve thread portion is screwed into a socket female thread portion by rotating the sleeve.
