Fluid Control Valve Installation With Shorter Stroke Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid control device installation methods face challenges in maintaining high controllability due to positional deviations and increased size, weight, and cost of construction equipment, particularly when inserting a valve body into a fluid pipe, as the extension stroke of the installation device can lead to overlapping connections and excessive load on existing pipes.
Innovation Solution
An installation method and device that includes an operation valve device with an annular sealing member to secure the valve housing in a sealed state, reducing the required pressing force and support points, and utilizing a split structure housing with a communication opening to ensure accurate positioning and reduce equipment size and weight, while preventing housing movement with movement prevention means during fluid pressure application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operation valve device is connected to the open end portion of the neck portion and the installation device is connected in an overlapping state, then the fluid control valve can be connected in a sealed state, but the extension stroke increases causing positional deviation and the equipment size and weight increase
Solution Approach 1:
Instead of connecting the operation valve device to the open end portion of the neck portion as in the prior art, the present invention connects the operation valve device to the opening formed in the neck portion. This inverted connection approach shortens the extension stroke of the installation device, eliminates positional deviation, and reduces equipment size and weight while maintaining sealed state connection reliability.
2Ease of manufacture
If the extension stroke of the installation device increases, then the fluid control valve can be installed, but positional deviation occurs such that the valve body cannot be inserted into the designed position
Solution Approach 1:
The present invention inverts the connection configuration by attaching the operation valve device to the opening in the neck portion rather than the open end portion. This inversion shortens the installation device's extension stroke, thereby eliminating positional deviation and ensuring the valve body is inserted into the designed position with high precision.
3Ease of manufacture
If construction equipment size increases to accommodate longer extension stroke, then the installation can be completed, but equipment and construction costs become expensive and weight causes excessive load on existing fluid pipes
Solution Approach 1:
The present invention inverts the traditional connection configuration, attaching the operation valve device to the opening in the neck portion instead of the open end portion. This inversion significantly shortens the required extension stroke of the installation device, thereby reducing equipment size and weight, lowering construction costs, and minimizing excessive load on existing fluid pipes.
