Press-Controlled Valve With Lateral Plate Flow Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressing-controlled valves cannot regulate the flow of fluid, only allowing on/off control, which limits their functionality in fluid control applications.
Innovation Solution
A pressing-controlled valve design incorporating a press structure with a press cap, positioning element, follower, and a pulling structure with a joint holder, shaft lever, springs, and guide block, allowing the movable valve plate to slide laterally and regulate fluid flow through a flow channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional pressing-controlled valve uses a press structure to pull a valve handle to move back and forth in axial direction, then the on/off control of internal flow path is achieved, but the valve cannot regulate the flow of water
Solution Approach 1:
The valve plate is designed to perform both axial movement (for on/off control) and lateral sliding movement (for flow regulation). The dynamic transformation of movement direction enables the valve to switch between binary control mode and continuous regulation mode, resolving the contradiction between ease of operation and adaptability.
Solution Approach 2:
The valve handle and driving mechanism are designed to provide multiple functions: axial pulling motion for on/off control and lateral sliding motion for flow regulation. This multi-functionality allows a single valve structure to satisfy both simple operation requirements and flow control versatility.
2Adaptability or versatility
If a pull-type control valve uses a valve handle to pull the driving seat to slide laterally, then the flow of water can be controlled, but the structure becomes more complex
Solution Approach 1:
The driving seat and valve plate are merged into an integrated component that performs both axial and lateral movements. By combining multiple functions into a single component, the structure avoids the complexity of separate mechanisms for on/off control and flow regulation.
Solution Approach 2:
The driving seat is designed as a multi-functional component that responds to axial pulling forces for on/off control and enables lateral sliding for flow regulation. This universal design reduces the need for additional specialized components.
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
Enhances handiness and control over fluid flow by enabling precise regulation of fluid flow through the valve, allowing for both on/off and flow adjustment.
Implementation Method 1
The shaft lever is axially put in the first spring. Both ends of the first spring stop the follower and the joint holder respectively.
Implementation Method 2
The second spring is disposed on one side of the drawing piece. One end of the second spring props the drawing piece, the other end of the second spring props the joint holder.
Implementation Method 3
the guide face presses the pressure face to force the drawing piece to slide laterally

AI summary
A pressing-controlled valve having a valve casing, a valve seat, a fixed valve plate, a movable valve plate, a driving piece, a press structure and a pulling structure, wherein the valve seat is assembled on one end of the valve casing. The fixed valve plate, movable valve plate and driving piece are disposed in the valve casing. A flow channel for fluid is formed among the valve seat, fixed valve plate and movable valve plate. The driving piece is in contact with the movable valve plate. The pulling structure includes a shaft lever, a guide block and a drawing piece. The press structure pulls the shaft lever the move, the shaft lever pulls the drawing piece through the guide block, so that the driving piece drives the movable valve plate to slide laterally, so as to enhance the handiness of flow control or the on/off of the flow channel.
