Abstract

A valve arrangement to ensure zero leakage from a blind flange valve is described. The blind flange valve is adapted to seal a pipeline into complete sealing according to set requirements. The base, or bottom, of the blind flange valve is in fluid communication with the inlet of an actuateable first valve that is in fluid communication with the inlet of a second actuateable valve. A fluid chamber is in fluid communication with the outlet from the first valve and the inlet of the second valve. The outlet from the second valve can be drained out, and that respective actuateable valves can be actuated by signal from predetermined sensor or sensors.

Claims

1. Valve arrangement to ensure zero leakage from a blind flange valve, which blind flange valve includes two discs that are adapted to seal in an upstream direction, respectively downstream direction, into complete sealing according to requirements, at the same time as the discs can be pulled into a closed chamber for full flow through the blind flange valve, wherein the base of the blind flange valve is in fluid communication with the inlet of an actuateable first valve, that the outlet of the actuateable first valve is in fluid communication with the inlet of a second actuateable valve, that a fluid chamber is in fluid communication with the outlet from the first valve and the inlet of the second valve, that the outlet from the second valve can be drained out, and that respective actuateable valves are actuated by signal from predetermined sensor or sensors.

2. Valve arrangement according to claim 1, wherein the first valve is connected to an actuator which is able to operate the first valve.

3. Valve arrangement according to claim 1, wherein the second valve is connected to a second actuator, which is able to operate the second valve.

4. Valve arrangement according to claim 1, wherein the blind flange valve is actuated by a third actuator, which has respective sensors which are able to register the end positions, or limits, of the actuator, corresponding to open/closed blind flange valve.

5. Valve arrangement according to claim 2, wherein the second valve is connected to a second actuator, which is able to operate the second valve.

6. Valve arrangement according to claim 2, wherein the blind flange valve is actuated by a third actuator, which has respective sensors which are able to register the end positions, or limits, of the actuator, corresponding to open/closed blind flange valve.

7. Valve arrangement according to claim 3, wherein the blind flange valve is actuated by a third actuator, which has respective sensors which are able to register the end positions, or limits, of the actuator, corresponding to open/closed blind flange valve.
