Judging from the diagram, it should be \"Why is an interlock cut-off valve installed at the vacuum pump outlet?\" ”For the “entrance”, right?
Prevent equipment downtime from affecting the process.
Imagine that, without the continuous operation of the chain, it’s very likely that the tank would be deflated, or that electrical damage could occur due to overload. Therefore, interlocks must be installed to ensure the safe operation of the equipment. For reference.
How can a suction tank form when the motor-stop interlock valve is in use?
The interlock valve that shuts off the motor is activated to protect the established vacuum and prevent it from being disrupted
Please read and understand the original poster’s topic carefully before asking questions.
Agree with the view from floor 7 – to prevent damage to the system’s vacuum
The vacuum pump outlet usually leads to the exhaust system, flare system, or is discharged directly into the atmosphere; if an interlock shut-off valve is not installed, gases from the backpressure side can flow back, posing a safety risk. Although there are check valves, they inevitably leak; relying on check valves to prevent backflow is not reliable. Only isolation valves with VI-grade sealing are the ultimate reliable solution
