Offset Rotary Water Valve Core for High-Flow Sealing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water control valves have limited flow capacity and high production costs due to the large space occupied by the rotation body and the need for multiple flowing passage configurations to accommodate various angles between water inlets and outlets, making it difficult to control flow rates, especially in applications like water spraying guns where continuous finger pressure is required.
Innovation Solution
A water control valve with an offset valve core featuring a rotary shaft and a water stopping seat with a sealing ring, where the offset rotary valve core is configured inside a flowing slot with a C-shaped flowing space, allowing for flexible allocation of water inlets and outlets and stepless control of water flow using a dialing component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotation body with flowing passage is used to control water flow, then the valve can turn on/off water flow and control flow rate, but the rotation body occupies large space which limits flow capacity
Solution Approach 1:
The valve core is divided into separate functional components: a rotating valve body for flow control and a fixed water stopping seat for sealing. This segmentation allows the valve body to be smaller and more compact while maintaining flow control capability, thereby increasing overall flow capacity without sacrificing reliability.
2Ease of operation
If the water inlet and outlet positions are adapted to the flowing passage of the rotation body, then the valve can control water flow through alignment, but multiple types of flowing passage must be formed for different angles which increases production cost and difficulty
Solution Approach 1:
The valve body is designed with a universal structure that can accommodate water inlets and outlets at different angles through a single standardized flowing passage configuration. The offset positioning and rotational capability allow the same valve body design to serve multiple angular requirements, eliminating the need to manufacture multiple specialized valve body types and thereby reducing production costs.
3Productivity
If a conventional water control valve is used in a water spraying gun, then the water flow can be controlled, but the user must continuously apply finger pressure which is inconvenient
Solution Approach 1:
The valve incorporates a trigger mechanism that utilizes the user's finger movement to automatically actuate the valve opening and closing. The mechanical linkage converts the triggering motion into rotational movement of the valve body, enabling flow control without continuous pressing force. This self-service mechanism improves operational convenience while maintaining effective flow control.

AI summary
A water control valve with offset valve core has a main body with a flowing slot, the circumferential wall of which is formed with a water inlet and outlet. An offset rotary valve core is configured offset inside the flowing slot and has a rotary shaft and a water stopping seat. The face of the water stopping seat faces the circumferential wall and has a sealing ring. When the water stopping seat rotates along with the offset rotary valve core and is aligned with the inlet, the sealing ring is pressed against the circumferential wall to close the inlet, thus forming the water stop mode. The rotary shaft and the circumferential wall of the flowing slot define a flowing space. The flow from the inlet must pass through the flowing space and exit through the outlet. A dialing component is used to connect and drive offset rotary valve core.
