Working principle of blind valve
Thread Content
1. From valve open to valve closed: The clamping motor activates, causing the screw to rotate counterclockwise; the valve body is released to its proper position (indicated by an indicator light). The drive motor then activates, causing the gate to rotate counterclockwise until it is fully closed (indicated by an indicator light). Finally, the clamping motor acts again, causing the screw to rotate clockwise, thereby securing the valve body in place (indicated by an indicator light), completing the entire process of closing the valve. 2. From closed to open: The clamping motor activates, causing the screw rod to rotate counterclockwise, thereby releasing the valve body to its proper position (indicated by the indicator light). Then the drive motor comes into action, causing the gate to rotate clockwise until it is fully opened (indicated by the indicator light), completing the entire process of opening the valve from a closed state.
What is the difference from a gate valve? Seeking advice
It is actually a type of gate valve. However, this is commonly used in pipelines for toxic, flammable, and explosive gas media. Its feature is \"absolute isolation,\" offering much stronger sealing performance than ordinary gate valves.
The key aspect is the high sealing level, right?
It’s actually a matter of the sealing level and the frequency of safe use
