| 摘要 |
The present invention relates to a system for regulating a liquid flowing in a circuit (1), the system comprising: a ball valve (200) comprising at least one inlet and one outlet, the ball (210) comprising an inner passage (212) through which the liquid flowing from the inlet toward the outlet of the valve (200) is intended to pass when the valve is at least partially open, an expansion reservoir (100) in communication with the liquid flowing in the circuit (1) and intended to contain liquid and a compensating gas, the ball comprising at least part of an expansion channel (213, 217, 218, 221) that has at least one lateral opening, the valve being configured such that at least when the valve is closed: the lateral opening is in direct communication with the liquid coming from the inlet or the outlet of the valve (200), when the valve is at least partially open, the lateral opening cooperates with an inner wall (207) secured to a body (201) of the valve (200) so as to form a pipe in communication on the one hand with the expansion reservoir (100) and on the other hand with the inner passage (212). The invention also relates to a circuit incorporating this system as well as a use of said system. |
