Dust Collector Diaphragm Valve Manual Emergency Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collector diaphragm valves cannot be manually operated in emergency situations when a timer or solenoid valve fails, leading to potential shutdowns and filter damage due to increased differential pressure.
Innovation Solution
A dust collector diaphragm valve with an emergency operation switch that allows manual operation by breaking internal equal pressure when the solenoid valve fails, using a rubber plate and spring mechanism to control air flow and prevent sudden pressure drops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a timer or solenoid valve is used for automatic operation, then automation is improved, but reliability deteriorates when the timer or solenoid valve fails
Solution Approach 1:
The patent introduces a manual emergency operation switch as an intermediary device that enables direct manual control of the diaphragm valve when the automatic control system (timer or solenoid valve) fails. This switch acts as a mediator between the operator and the valve, allowing emergency operation without requiring the automatic control system to function.
Solution Approach 2:
The patent incorporates a manual emergency operation switch as a backup measure in advance, so when the timer or solenoid valve fails, the system can immediately switch to manual operation without interruption. This prior cushioning ensures continuous operation by preparing an alternative control method before failure occurs.
2Device complexity
If the diaphragm valve cannot be operated in emergency, then device complexity is reduced, but harmful factors increase due to filter damage
Solution Approach 1:
The manual emergency operation switch serves as a simple intermediary device that directly controls the diaphragm valve without requiring complex control systems. This switch provides a straightforward mechanical or electrical connection that enables valve operation even when the main control system fails, preventing filter damage with minimal added complexity.
3Reliability
If manual emergency operation is added, then reliability is improved, but device complexity increases
Solution Approach 1:
The manual emergency operation switch is designed as a standalone intermediary component that integrates into the existing diaphragm valve system without requiring major structural modifications. It provides emergency control capability through a simple addition that maintains the original valve structure while enabling manual operation.
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
Enables manual operation of the diaphragm valve during emergencies, preventing shutdowns and filter damage by maintaining stable pressure and extending filter lifespan.
Implementation Method 1
a spring (37) installed at a center of a back side of the rubber plate (35) in order to return (move forward) the rubber plate (35) until an operation of the solenoid valve (36) is stopped
Implementation Method 2
a solenoid valve (36) configured to be installed behind the cover (34) so that an internal plunger (36a) instantaneously opens the pressure vent (34b)

AI summary
A dust collector diaphragm valve capable of performing manual emergency operation according to the present invention is configured to perform control so that the internal equal pressure of the diaphragm valve can be broken due to an internal pressure drop attributable to an instantaneous air discharge occurring whenever an emergency operation switch is manually pressed when a pulse operation signal or solenoid valve used to operate the diaphragm valve fails, and thus a rubber plate installed between the body and cover of the diaphragm valve can be turned (moved forward) after being instantaneously moved backward. Accordingly, dedusting work can be manually performed according to the determination of a manager, and thus the dust collector diaphragm valve can prevent an emergency shutdown during the operation of a dust collector and can also prevent a filter from reaching a limit differential pressure, thereby preventing the lifespan of the filter from being shortened.
