Electric Valve Passage for Powder Impurity Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Powder impurities accumulate in the inner chamber of electric valves, leading to reduced operational efficiency and shortened service life.
Innovation Solution
The electric valve design includes a passage that communicates between the sleeve chamber and the valve body chamber, allowing powder impurities to flow from the sleeve chamber into the valve body chamber and subsequently into the system pipeline, thereby reducing accumulation and improving operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmission mechanism operates for a period of time, then the valve achieves fluid blocking/communication function, but powder impurities are produced and accumulated in the inner chamber
Solution Approach 1:
The patent extracts the harmful powder impurities from the inner chamber by designing a passage that connects the inner chamber to the external environment. This allows the impurities to be discharged outward, separating the harmful byproducts from the functional chamber, thereby resolving the contradiction between maintaining reliable operation and preventing impurity accumulation.
Solution Approach 2:
The patent implements a discarding mechanism for the powder impurities generated during transmission mechanism operation. The passage enables these impurities to be discarded from the inner chamber through the valve body outlet, allowing continuous operation without impurity buildup that would compromise reliability.
2Duration of action of moving object
If powder impurities accumulate in the inner chamber, then the transmission mechanism continues to operate, but the operating state deteriorates and service life shortens
Solution Approach 1:
The passage extracts powder impurities from the inner chamber, preventing their accumulation that would otherwise deteriorate the operating state. By continuously removing these impurities, the transmission mechanism can maintain optimal operating conditions throughout its service life.
Solution Approach 2:
The passage is pre-configured in the valve body to enable impurity discharge before significant accumulation occurs. This preliminary structural arrangement ensures that impurities can be removed promptly, preventing operating state deterioration and extending service life.
3Object-generated harmful factors
If the passage is designed to communicate the sleeve chamber and valve body chamber, then powder impurities can be flushed out, but the structural complexity increases
Solution Approach 1:
The passage is merged with the existing valve body structure, integrating the impurity discharge function into the main body rather than adding a separate component. This combines the sealing chamber and discharge pathway into a unified structure, reducing overall device complexity while effectively removing powder impurities.
Solution Approach 2:
The valve body is designed with multi-functionality, serving both as the structural housing and as the conduit for impurity discharge through the integrated passage. This universal design eliminates the need for separate discharge components, reducing structural complexity while maintaining effective impurity removal.
