Abstract
An air regulation system for a hydropneumatic reservoir of a hydraulic conduit includes a chamber, a water filling device for the chamber, a water emptying device for the chamber, an automatic air introduction device for introduction of air in the chamber during emptying, an automatic injection device for injecting air from the chamber to the reservoir during filling, and a control device connected to at least one excess sensor for sensing the overpassing of a threshold level of water contained in the reservoir and also connected to a chamber filling and emptying assembly. If the sensor indicates an insufficient air volume in the reservoir, the control device initiates chamber filling/emptying cycles until the sensor indicates that the air volume in the reservoir is sufficient.
Claims27
Air regulation system for a hydropneumatic reservoir (1) of a water pipe (2), comprising a chamber (6), a means (11, 12;
- 3;
- 11, 27a) for filling the chamber with water, a means (10, 13;
- 27b, 28) for draining the chamber of water, a means (14, 15, 16) for automatically introducing air into the chamber during drainage, a means (18, 19;
- 8) for automatically injecting air from the chamber toward the reservoir during filling, and said air regulation system further comprises a control means (22) connected to at least one detector (23;
- 23a, 23b) which detects that a threshold level for the water contained in the reservoir has been exceeded, and to the means for filling and draining the chamber, and that if, for a given state, the detector indicates that the volume of air contained in the reservoir is insufficient for this state, the control means initiates chamber filling/draining cycles until the detector indicates that the volume of air in the reservoir has become sufficient.
