Valve Body Unit Replacement Ring for Easy Stem Disengagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve devices require laborious disengagement of the replaceable component unit from the spindle to attach or detach, making the replacement process inefficient.
Innovation Solution
A valve device design featuring a tubular bonnet, a driving portion, a stem, a valve body unit, a replacement ring, and a connecting mechanism that allows for easy disengagement of the valve body unit by using a driving force to move the stem and valve body unit to the valve seat side, pushing the replacement ring to decrease in diameter and drop onto a ring dropping portion, and then releasing the connection between the stem and the valve body unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the replaceable component unit is designed to be detachable from the spindle, then the valve body unit can be replaced, but the disengagement process becomes extremely laborious
Solution Approach 1:
A replacement ring is introduced as an intermediary component between the valve body unit and the bonnet. The replacement ring features an elastic deformation capability that allows it to be compressed by the driving portion, enabling automatic disengagement of the valve body unit from the stem without manual labor. The replacement ring acts as a mediator that transforms the complex disengagement operation into a simple driving action.
Solution Approach 2:
The replacement ring is designed with elastic properties that enable it to automatically return to its original shape after being compressed by the driving portion. This self-service mechanism allows the valve body unit to disengage automatically when the replacement ring expands after compression, eliminating the need for manual intervention in the disengagement process.
2Ease of operation
If the replacement ring is made elastic to enable automatic disengagement, then the operation becomes easier, but the structural complexity increases
Solution Approach 1:
The replacement ring serves multiple functions: it acts as a connecting element between the valve body unit and the bonnet, provides elastic deformation for automatic disengagement, and transmits the driving force from the driving portion. By making the replacement ring perform multiple functions, the patent avoids adding separate complex mechanisms for each function, thereby limiting the increase in structural complexity.
Solution Approach 2:
The replacement ring's key parameter is its elasticity, which allows it to change shape in response to the driving force. By utilizing this parameter change (elastic deformation), the patent achieves automatic disengagement without requiring complex mechanical linkages or additional components, thus balancing ease of operation with acceptable structural complexity.

AI summary
A valve body unit is configured to be disengaged from a stem by moving the stem and the valve body unit to a valve seat side in a state where a bonnet is separated from the valve seat, thereby pushing a replacement ring such that the replacement ring moves through the bonnet while decreasing in diameter and then drops down onto a ring dropping portion in the free state, then moving the stem, the valve body unit, and the replacement ring to an opposite side to the valve seat side such that a first surface comes into contact with a second surface and the ring dropping portion comes into contact with the replacement ring, and in this state, moving only the stem to the opposite side to the valve seat side such that the connection formed by a connecting mechanism between the stem connection portion and the stem is released.
