| titleOfInvention | Negative pressure pipeline valve, negative pressure control system and negative pressure water pipeline network |
| abstract | The utility model relates to a negative pressure pipeline valve, a negative pressure control system and a negative pressure water delivery pipeline network. The valve body of the negative pressure pipeline valve is provided with an inner tube, the two axial ends of the inner tube are sealed and connected to the valve body, and the axial middle part of the inner tube is opened and closed inwardly concave on both sides of the lateral direction. structure, a gap is left between the lateral sides of the opening and closing structure and the inner wall of the valve body, and the side wall of the valve body is provided with a first control interface and a second control interface. The negative pressure control system adopts the negative pressure pipeline valve, the first control interface of which is connected to the outlet side pipeline through the negative pressure control air circuit, and the second control interface is connected to the positive pressure air source or the pressureless air source through the positive pressure control air circuit. The negative pressure water delivery pipeline network adopts a tree-like arrangement, and is provided with a partition monitoring station, and the negative pressure pipeline valve is arranged on the corresponding delivery pipeline. This kind of negative pressure pipeline can improve the service life, reduce the negative pressure energy loss caused by the valve closing is not strict, and reduce the maintenance and operation cost of the pipe network system. |
