Safety system for a pressure accumulator

A safety system, comprising:

• a valve block with first and second valve ports and a pressure supply port;
• first and second gas safety valves connected in fluid communication connected to the valve block via the first and second valve ports, respectively;
• a first pressure accumulator holding a gaseous pressure medium and being connected in fluid communication to the valve block via the pressure supply port;
• gas-conveying lines in the valve block connecting the pressure supply port and the first and second valve ports;
• independently operable first and second control valves connected in the gas-conveying lines between the pressure supply port and the first and second valve ports, respectively, such that fluid communication between the pressure supply port and one of the first and second valve ports is open while fluid communication to the other of the first and second valve ports is blocked;
• and
• first and second control disks on the first and second control valves, respectively, mechanically locking the first control valve in an open position thereof when the second control valve is rotated to a closed position thereof and mechanically locking the second control valve in an open position thereof when the first control valve is rotated to a closed position thereof.

• first and second hand levers on the first and second control valves, respectively, rotating the first and second control valves individually between respect open and closed positions thereof;
• first and second control disks on the first and second control valves, respectively;
• and
• first and second stop limits on the valve block interacting with the first and second control disk, respectively, limiting rotation of the first and second hand levers to 90 degree rotations between the open positions in which the respective hand lever is parallel to a longitudinal direction of the respective gas safety valve and the closed positions in which the respective hand lever is transverse to the longitudinal direction of the respective gas safety valve.

• first and second gas safety valves connected in fluid communication connected to the valve block via the first and second valve ports, respectively;
• a first pressure accumulator holding a gaseous pressure medium and being connected in fluid communication to the valve block via the pressure supply port;
• gas-conveying lines in the valve block connecting the pressure supply port and the first and second valve ports;
• and
• a mechanical three position control valve connected in the gas-conveying lines between the pressure supply port and the first and second valve ports selectively connecting in fluid communication the first and second valve ports to the pressure supply port in a first position of the control valve, connecting the first valve port to the pressure supply port and blocking fluid communication of the second valve port and the pressure supply port in a second position of the control valve, and connecting the second valve port to the pressure supply port in fluid communication and blocking fluid communication between the first valve port and the pressure supply port in a third position of the control valve.

A safety system, comprising:

• a valve block with first and second valve ports and a first supply pressure port;
• first and second safety valves connected in fluid communication to the valve block via the first and second valve parts, respectively;
• gas-conveying lines in the valve block connecting the first pressure supply port to the first and second pressure ports;
• a control valve device in the gas-conveying lines selectively and independently opening and blocking flow between the pressure supply port and the first and second valve ports such that fluid communication between the pressure supply port and at least one of the first and second valve ports is open while fluid communication to the other of the first and second valve ports is able to be blocked;
• and
• a control chip of a chip controlled actuation system permits operation of the control valve device controlling fluid communication of the first and second valve ports to the pressure supply port if a hydraulic accumulator is deployed at the pressure supply port and stops operation of the control valve device if the hydraulic accumulator supply system is removed from the pressure supply port with the control valve device blocking fluid communication connections between the first and second valve ports and the pressure supply port.
