In addition, in order to facilitate the adjustment of the operator, the fire-fighting pressure stabilizing pump 11 on the fire-fighting pressure stabilizing water supply pipeline 1 preferably has two states of manual control and automatic control.
The utility model discloses working process mainly includes following step:
s1, closing a first adjusting valve 51, manually starting a fire-fighting pressure stabilizing pump 11 on a fire-fighting pressure stabilizing water supply pipeline 1, wherein at the moment, water flowing out of the fire-fighting pressure stabilizing water supply pipeline 1 can completely enter a measuring pipeline 4, and the instantaneous flow measured by a flow meter 41 is the actual outlet flow of the fire-fighting pressure stabilizing pump 11 (namely the maximum design flow required by the second operating state specification). During the measurement, can also open and adjust the opening degree of second adjusting valve 61 for the measurement water can flow back to fire water tank 2 through second return line 6.
S2, opening a first regulating valve 51, wherein at the moment, water flowing out of the fire-fighting pressure-stabilizing water supply pipeline 1 can flow back to the fire-fighting water tank 2 through a first return pipeline 5, so that water supply of the fire-fighting pressure-stabilizing water supply pipeline 1 can be appropriately divided by the first return pipeline 5; the opening degree of the first adjusting valve 51 is adjusted until the instantaneous flow reading of the flow meter 41 meets the design flow of the first operation state, at this time, the actual flow of the water outlet pipeline 3 can meet the standard requirement of the first operation state, the flow adjustment is finished, and the fire-fighting pressure stabilizing pump 11 enters an automatic control state (namely, the conventional fire-fighting state of automatically starting to extinguish a fire after receiving a fire-fighting alarm).
In the flow control process, the opening degree of the second regulating valve 61 can be opened and regulated to ensure that the water for regulation can flow back to the fire water tank 2 through the second return pipeline 6, and after the flow control is finished, the second regulating valve 61 is closed.
S3, monitoring the daily accumulated water quantity in real time by using the flowmeter 41, and if the daily accumulated water quantity has no obvious change, indicating that the fire-fighting main pipe network normally operates in a first operation state (namely a non-leakage state); if the daily accumulated water amount is obviously increased, the leakage of the fire-fighting main pipe network is indicated, and the leakage flow can be calculated by utilizing the increased accumulated water amount. The increased cumulative amount of water is divided by the leakage time to obtain the leakage flow, for example, if the cumulative amount of water within 24 hours is significantly increased by 48m compared with the cumulative amount of water counted in daily life 3 Then the 24 hour leakage can be considered to be 48m 3 The leakage flow rate is 48m 3 /24h＝2m 3 /h。
And S4, if the fire-fighting main pipe network has leakage, repeating the flow regulation process in the step S1 and the step S2, after the actual flow of the fire-fighting pressure stabilizing pump 11 is measured, regulating the opening degree of the first regulating valve 51 to enable the instantaneous flow reading of the flow meter 41 to meet the flow requirement of a second running state (namely, the leakage state), namely the sum of the designed flow and the leakage flow of the first running state, at the moment, the actual flow of the water outlet pipeline 3 can meet the standard requirement of the second running state, and after the flow regulation is finished, the fire-fighting pressure stabilizing pump 11 recovers the automatic control state.
For example, suppose the actual outflow of the fire protection surge pump 11 is 5m 3 The design flow required by the first operation state specification of the fire-fighting main pipe network is 1m 3 H, leakage flow rate of 2m 3 H, then the opening of the first regulating valve 51 needs to be adjusted so that the instantaneous flow reading of the flow meter 41 is 3m 3 H (remaining 2 m) 3 And/h is shunted and flows back to the fire water tank 2 through the first regulating valve 51), and the standard requirement of the second running state of the fire-fighting main pipe network can be met. It will be appreciated that the flow regulation process described above can be performed either manually by an operator or automatically by a controller, i.e. by means of a controllerReceiving the real-time monitoring result of the flowmeter 41, judging the running state of the fire-fighting main pipe network, and controlling the first regulating valve 51 and the second regulating valve 61 to regulate the flow according to the judgment result.
