Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angle valve structures with spherical valve cores suffer from wear and inadequate sealing, leading to water leakage over time, failing to meet current demands for reliability and durability.
Innovation Solution
An angle valve structure featuring a rotatable valve core with an elastic arm and a sealing block, where the extrusion portion contacts the inner wall of the accommodation cavity to press the sealing block against the water outlet channel for sealing, and a snap-fit connection with a water inlet joint for secure attachment, utilizing wear-resistant components to minimize long-term wear and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spherical valve core is used, then the valve can be operated easily, but wear occurs between the valve core and valve body leading to poor sealing and water leakage
Solution Approach 1:
The valve core is divided into a main body part and a separate sealing block, allowing the sealing function to be isolated and optimized independently from the operating mechanism
Solution Approach 2:
An elastic arm acts as an intermediary between the valve core main body and the sealing block, transmitting force while maintaining constant contact pressure to ensure reliable sealing
2Device complexity
If a spherical valve core with through hole is used, then the structure is simple, but wear between valve core and valve body causes sealing failure
Solution Approach 1:
The valve core structure is segmented into the main body part for operation and a separate sealing block for sealing, reducing wear on critical sealing surfaces
Solution Approach 2:
The sealing mechanism changes from direct contact between spherical valve core and valve body to an elastic arm-mediated contact system, maintaining sealing pressure while reducing wear
3Device complexity
If the sealing block is directly connected to the valve core, then the structure is simple, but wear and insufficient sealing occur over time
Solution Approach 1:
The elastic arm serves as a mediator between the valve core main body and sealing block, providing continuous contact force to maintain sealing effectiveness while allowing for wear compensation
Solution Approach 2:
The connection between valve core and sealing block changes from rigid direct connection to elastic arm-mediated connection, enabling dynamic adjustment of sealing pressure
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
The design enhances sealing efficacy by using water pressure and the elastic arm's force to maintain a tight seal, while the snap-fit connection ensures durability and ease of assembly/disassembly, offering a cost-effective and user-friendly solution with improved durability and performance.
Implementation Method 1
the valve core includes a main body part and an elastic arm whose one end is connected with the main body part... one side of the elastic arm is provided with an extrusion portion, and the other side of the elastic arm is provided with a contact portion extending into the mounting slot and butting against the sealing block
Implementation Method 2
uses the pressure of water and the force of the contact portion to strengthen the sealing effect and effectively prevent water leakage

AI summary
The present disclosure relates to an angle valve structure, including an angle valve body. The angle valve body is provided with a water inlet channel, a water outlet channel and an accommodation cavity. The accommodation cavity is rotationally provided with a valve core. One end of the valve core exposed outside the accommodation cavity is fixedly connected with a knob. The valve core is provided with a sealing block for sealing the water outlet channel when sealing. The valve core includes a main body part and a elastic arm whose one end is connected with the main body part. One side of the main body part is provided with a mounting slot for placing the sealing block, one side of the elastic arm is provided with an extrusion portion, and the other side of the elastic arm is provided with a contact portion against the sealing block after assembly. When the angle valve is closed, the extrusion portion butts against the inner wall of the accommodation cavity, so that the sealing block butts against the water outlet channel to complete the sealing under the action of the inner wall of the accommodation cavity. When the angle valve is opened, the extrusion portion butts against the inner wall of the accommodation cavity, so that the contact portion butts the sealing block against the inner wall of the accommodation cavity. The water pressure and the force of the contact portion are used to strengthen the sealing effect and effectively prevent water leakage.
