Abstract

The valve (1) comprises a body (2) delimiting a conduit (4) and having a connection portion (6) where one end of the conduit (4) opens, the connection portion (6) being intended to be connected to the storage tank (100). In addition, said valve (1) comprises a clamping member (22) movably mounted on the connection portion (6) in order to keep the connection portion (6) attached to the storage tank sealing member (10) able to rotate in the conduit (4) between a closed position in which the sealing member (10) seals the conduit (4) and an open position in which the sealing member (10) opens a passage through the conduit (4), two seats (24) interposed between the sealing member (10) and the valve body (2), and elastic return means configured to keep the seats (24) and the sealing member (10) pressed together. The conduit (4) has an angled portion (42) arranged between the connection portion (6) and the sealing member (10).

Claims

1. A valve for a uranium hexafluoride storage tank, comprising a valve body, the valve body delimiting a duct and having a connector portion where an end of the duct opens, the connector portion being intended to be connected to the storage tank, characterized in that the valve comprises

a clamping member movably mounted on the connector portion between a loosening position in which the clamping member is intended to allow a disengagement of the portion of the connector from the storage tank and a clamping position in which the clamping member is intended to hold the connector portion fastened to the storage tank,

an obturation member movable in rotation in the duct between a closing position in which the obturation member obturates the duct and an opening position in which the obturation member releases a passage through the duct,

two seats interposed between the obturation member and the valve body, and

an elastic biasing element configured to hold the seats and the obturation member in bearing contact, and in that

the duct has a bent portion, the bent portion being arranged between the connector portion and the obturation member.

2. The valve according to claim 1, wherein the seats comprise a flexible material.

3. The valve according to claim 1, wherein the valve comprises a double sealing arrangement.

4. The valve according to claim 3, wherein the double sealing arrangement comprises at least a first sealing barrier made of a first material, and a second sealing barrier made of a second material distinct from the first material.

5. The valve according to claim 1, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, and a reducer linking the control member and the obturation member.

6. The valve according to claim 1, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, the control member being fully contained in the valve body or, where appropriate, the reducer.

7. The valve according to claim 1, wherein the valve comprises a temperature sensor for measuring the temperature of the duct.

8. The valve according to claim 2, wherein the valve comprises a double sealing arrangement.

9. The valve according to claim 8, wherein the double sealing arrangement comprises at least a first sealing barrier made of a first material, and a second sealing barrier made of a second material distinct from the first material.

10. The valve according to claim 9, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, and a reducer linking the control member and the obturation member.

11. The valve according to claim 10, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, the control member being fully contained in the valve body or, where appropriate, the reducer.

12. The valve according to claim 11, wherein the valve comprises a temperature sensor for measuring the temperature of the duct.

13. The valve according to claim 2, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, and a reducer linking the control member and the obturation member.

14. The valve according to claim 3, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, and a reducer linking the control member and the obturation member.

15. The valve according to claim 4, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, and a reducer linking the control member and the obturation member.

16. The valve according to claim 2, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, the control member being fully contained in the valve body or, where appropriate, the reducer.

17. The valve according to claim 3, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, the control member being fully contained in the valve body or, where appropriate, the reducer.

18. The valve according to claim 4, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, the control member being fully contained in the valve body or, where appropriate, the reducer.

19. The valve according to claim 5, wherein the valve comprises a control member intended to be actuated by a user in order to control the opening or the closing of the valve, the control member being fully contained in the valve body or, where appropriate, the reducer.

20. The valve according to claim 2, wherein the valve comprises a temperature sensor for measuring the temperature of the duct.
