Abstract
The utility model discloses a kind of interlockings of space division expanding machine hardwire, with Central Control Room DCS control system devices, relay, expanding machine emergency stop push button, supercharger return valve, expanding machine quick action emergency valve, expanding machine operating status feedback signal line, it is connected as a result of Central Control Room DCS control systems device with expanding machine quick action emergency valve, expanding machine quick action emergency valve, relay is in parallel, Central Control Room DCS control system devices, relay, supercharger return valve is sequentially connected, relay is connected with expanding machine emergency stop push button, the structure that relay is connected by expanding machine operating status feedback signal line with Central Control Room DCS control system devices, effectively prevent supercharger superpressure, protect unit safety operation, it avoids during Central Control Room DCS control system plant failures supercharger return valve that from cannot opening and causes system overpressure.The utility model is characterized in that simple in structure, at low cost, operation is practical.
Description
Technical field
The utility model is related to a kind of space division expanding machine interlocks, are directly related to a kind of space division expanding machine hardwire connection
Lock.
Background technology
Country's space division expanding machine interlocking at present is mostly that DCS internal logics are realized, this patent interlocks process by instrument signal line
Connection, and do not influence DCS it is original protection it is chain, it is relatively reliable to expanding machine safe operation.
The content of the invention
Hardwire interlocking is realized in a kind of space division expanding machine interlocking of this practicality, securely and reliably, avoids influencing unit during DCS failures
Safe operation.
What the purpose of this utility model was realized in：A kind of space division expanding machine hardwire interlocking, has Central Control Room DCS controls
System and device processed, relay, expanding machine emergency stop push button, supercharger return valve, expanding machine quick action emergency valve, expanding machine operation
Status feedback signal line, Central Control Room DCS control systems device are connected with expanding machine quick action emergency valve, expanding machine quick action emergency valve,
Relay is in parallel, and Central Control Room DCS control systems device, relay, supercharger return valve are sequentially connected, and relay is tight with expanding machine
Anxious stop button is connected, and relay is connected by expanding machine operating status feedback signal line with Central Control Room DCS control system devices.
The relay has induction coil, expanding machine operating status relay contact, expanding machine emergency stop push button contact, supercharger
Return valve contact.
It is connected since the utility model employs Central Control Room DCS control systems device with expanding machine quick action emergency valve, expands
Machine quick action emergency valve, relay are in parallel, and Central Control Room DCS control systems device, relay, supercharger return valve are sequentially connected, after
Electric appliance is connected with expanding machine emergency stop push button, and relay is controlled by expanding machine operating status feedback signal line and Central Control Room DCS
System and device processed is connected.There is the relay induction coil, expanding machine operating status relay contact, expanding machine to stop in emergency
Push-button contact, the structure of supercharger return valve contact, expanding machine quick action emergency valve are closed, and relay coil dead electricity, relay moves
Make, supercharger return valve standard-sized sheet, expanding machine emergency stop push button action, expanding machine run signal loses, effectively prevents being pressurized
Machine superpressure, while alarm signal is sent to Central Control Room DCS control system devices, unit safety operation is protected, avoids Central Control Room DCS
Supercharger return valve cannot be opened and cause system overpressure during control system plant failure.
Description of the drawings
Attached drawing 1 shows the structure diagram of the utility model, and 1 pair of the utility model is made furtherly below in conjunction with the accompanying drawings
It is bright.
Specific embodiment
