Low-Height Bonnet Structure for Flush-Mounted Water Supply Valves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional valves for continuous water supply protrude outward from the ground when the pipe depth is close to the ground, necessitating an inclined installation, causing construction inconveniences.
Innovation Solution
A height-adjustable valve design featuring a bonnet structure with a low-height insert body and fixing cover that allows the bonnet to be lowered and maintained at a reduced height by applying pressing force during construction, using a low-height insert body and fixing cover to accommodate the valve disc.

Engineering Contradiction Analysis
1Length of stationary object
If the valve uses a conventional bonnet structure, then the valve can accommodate the valve disc properly, but the valve protrudes above ground when pipe depth is close to ground
Solution Approach 1:
The bonnet is divided into two separate components: a lower bonnet fixed to the valve body and an upper bonnet that can be adjusted in height. This segmentation allows the upper bonnet to be positioned at different heights depending on the installation conditions, particularly when the pipe depth is close to the ground surface.
Solution Approach 2:
The upper bonnet is designed to be movable relative to the lower bonnet, allowing it to be adjusted to different heights during installation. The upper bonnet can be positioned at multiple height levels and fixed in place, providing dynamic adaptability to different ground levels and pipe depths.
2Length of stationary object
If the valve protrudes above ground, then the bonnet can accommodate the valve disc, but the valve must be installed in an inclined state
Solution Approach 1:
Instead of adjusting the horizontal position or orientation of the valve, the solution moves the adjustment to the vertical dimension by providing a movable upper bonnet that can be positioned at different heights. This allows the valve to remain horizontally level while adapting to varying ground elevations.
3Length of stationary object
If the bonnet height is reduced, then the valve can be installed flush with ground, but the valve disc accommodation space is reduced
Solution Approach 1:
By dividing the bonnet into lower and upper sections, the accommodation space for the valve disc is maintained in the lower bonnet which remains at a sufficient height, while the upper bonnet provides the additional height adjustment capability needed to reach the ground surface.

AI summary
Provided is a height-adjustable valve for continuous water supply. Specifically, provided is a valve for continuous water supply, structured such that a bonnet for containing a valve disc has a reduced height. Conventionally, when installing a valve for continuous water supply, if the tubular depth is close to the ground, a part of the structure protrudes out of the ground, and the structure needs to be slanted and installed. In order to overcome such an inconvenience, the height of the bonnet for containing a valve disc is improved by making same lower than in conventional cases, thereby providing the height-adjustable valve for continuous water supply.
