流体流动控制阀
摘要：
流体流动控制阀，包括：用于与供应管连接的入口(E)；用于与排放管连接的出口(S)；活动阀瓣(1)，其息止时支靠在阀瓣座(2)上，以隔离所述入口(E)和所述出口(S)；用于移动所述活动阀瓣(1)的动作部件(5、C)，所述动作部件包括：腔室(C)，其通过具有确定截面的孔眼(11)与所述入口(E)连通，所述腔室(C)相对于所述阀瓣(1)处在与所述座(2)相反的一侧，以便把所述阀瓣推到它的座上；及旁路(5)，其连接所述腔室(C)至所述出口(S)，所述旁路在流体通过的开放状态和关闭状态之间是可控制的，该旁路的通过截面大于所述孔眼(11)的截面，从而通过打开所述旁路而使所述腔室内的压力下降；其特征在于，所述阀集成有流体渗漏检测部件(4、5、6)，所述流体渗漏检测部件能够检测所述活动阀瓣下游的渗漏。
摘要（英）：

The invention concerns a fluid flow control valve comprising: an intake (E) designed to be connected to a supply line, an outlet (S) designed to be connected to a discharge line, a mobile check valve (1) supported, at rest, on a check valve seat (2) so as to isolate the intake (E) from the outlet (S), actuating means (5, C) for moving the mobile check valve (1), said means including: a chamber (C) communicating with the intake (E) via a hole (11) of specific cross-section, the chamber (C) being arranged relative to the check valve (1) on the side opposite to the seat (2), so as to urge the check valve on its seat, and a bypass (5) connecting the chamber (C) to the outlet, the bypass being controllable between an open state for allowing through fluid and a closed state, the bypass having apassage cross-section greater than that of the hole (11) so as to cause the pressure to drop in the chamber when the bypass is open. The invention is characterized in that it incorporates fluid leakage sensing means (4, 5, 6) adapted to detect a leak downstream of the mobile check valve.
