Valve Device Nozzle Orifice Segmentation for Cleaning Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional valve devices for applying fluid to substrates face challenges in cleaning and maintenance, particularly due to the risk of blockages and deposits, which require extensive disassembly and result in lost adjustment settings and inefficient cleaning processes.
Innovation Solution
The design incorporates a nozzle plate with a mounting opening for the valve piston, a valve housing forming a rectilinear fluid duct that can be easily accessed for cleaning, and a detachable nozzle orifice that maintains adjustment settings, allowing for effective flushing without disassembling the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the valve device is disassembled for cleaning, then the cleaning effectiveness is improved, but the adjustment settings are lost and the maintenance time increases
Solution Approach 1:
The valve device is segmented into a removable valve housing that can be separated from the valve body. This allows the valve housing to be detached for cleaning while the valve body with adjustment settings remains in place, enabling partial disassembly that maintains adjustment settings while improving cleaning access
Solution Approach 2:
The valve housing containing the valve nozzle is extracted as a separate removable component. This extraction allows cleaning fluid to access the valve nozzle and fluid paths without requiring removal of the entire valve device or loss of adjustment settings on the valve body
2Ease of operation
If the valve housing is made detachable for cleaning access, then the cleaning accessibility is improved, but the structural complexity increases
Solution Approach 1:
The valve device is divided into two main segments: a removable valve housing and a fixed valve body. This segmentation provides cleaning accessibility to the valve nozzle while keeping the overall structure relatively simple through a straightforward connection interface
Solution Approach 2:
The valve housing serves multiple functions: it houses the valve nozzle, provides a removable cover for cleaning access, and maintains structural integrity when assembled. This multi-functionality reduces the need for additional components, thereby limiting the increase in structural complexity
3Reliability
If the fluid duct has rectilinear design, then the flow efficiency is improved and deposits are reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The fluid duct design implements rectilinear (corner-free) geometry specifically in the critical flow paths where deposits are most likely to form. This localized application of smooth flow paths improves reliability without requiring rectilinear design throughout the entire device, thereby limiting the increase in manufacturing precision requirements

Function Achieved in This Case
This design enables efficient cleaning and maintenance of valve devices with reduced risk of blockages and deposits, maintaining adjustment settings and preventing flow shadows, while also improving the longevity of the electromagnetic device through effective deaeration and cooling.
Implementation Method 1
an electromagnetic device with valve piston movable back and forth against a return force and engaging in the valve seat for opening and closing the valve nozzle
Implementation Method 2
at least one rectilinear fluid duct that remains free from flow corners and that, passing the valve actuating device, connects the supply fluid chamber to the valve seat
Implementation Method 3
valve piston movable back and forth against a return force and engaging in the valve seat for opening and closing the valve nozzle

AI summary
A valve device of an application device for applying fluid to a substrate comprises a valve body, a valve housing with inner chamber and valve seat, a supply fluid chamber, an electromagnetic valve actuating device with valve piston and an adjusting piston. The valve nozzle is detachably mounted on the nozzle side of the valve device. The valve device has a nozzle plate which closes the valve body at the bottom on the nozzle side, with mounting opening for the valve piston. The valve housing is designed in the form of a nozzle orifice which is a closure member that can be fitted on the mounting opening from below and removed. The valve nozzle forms part of the valve housing. The valve piston is exposed through the mounting opening of the nozzle plate for removal and fitting when the closure member is removed. The valve device is provided with at least one rectilinear fluid duct that connects the supply fluid chamber to the valve seat. The valve piston and part of the adjusting piston together form a wall of the straight fluid duct which, when the nozzle orifice closure member is removed, is exposed for cleaning through the mounting opening. An application device comprises the valve devices arranged in a row.
