as shown in fig. 1, the box-type non-negative-pressure community water supply system shown in this embodiment includes a municipal pipe network end water inlet pipe 1, a water distribution pipe, a user pipe network end water outlet pipe 2, a water reservoir 4 and a water storage tank 3. During normal water supply, municipal administration pipe network end inlet tube 1 provides great discharge, and most water is transmitted to user pipe network end outlet pipe 2 by the distributive pipe and is supplied water to the user this moment, and remaining water is carried to storage water tank 3 by the distributive pipe with the constant velocity of flow, whether the water in the control storage water tank 3 is carried to cistern 4 in according to actual conditions.
Specifically, the distributive pipe comprises a first water pipe 5, a water inlet 15 and a first water outlet 13 are arranged on the water storage tank 3, the water inlet end of the first water pipe 5 is communicated to the municipal pipe network end water inlet pipe 1, the water outlet end of the first water pipe 5 is communicated to the water inlet 15, a third water pipe 11 is arranged between the first water outlet 13 and the water storage tank 4, and the first water outlet 13 is communicated to the water storage tank 4 through the third water pipe 11. When the water is normally supplied, a part of water flow of the water inlet pipe 1 at the municipal pipe network end flows into the water storage tank 3 through the first water pipe 5 to be stored. The volume and the maximum water storage capacity of the water storage tank 3 are not large, and the water in the water storage tank 3 is used as a supplementary water source when the water is cut off for a short time. When the maximum water storage capacity in the water storage tank 3 is reached, redundant water flows into the water storage tank 4 through the first water outlet 13, the volume and the maximum water storage capacity of the water storage tank 4 are far larger than those of the water storage tank 3, and therefore a large amount of water stored in the water storage tank 4 can be used as a supplementary water source during long-term water cut-off.
In order to achieve the above purpose, the first water pipe 5 is provided with a throttle valve 8. When the first water outlet 13 supplies water normally, the throttle valve 8 on the first water pipe 5 is adjusted, so that water enters the first water pipe 5 at a fixed flow rate, and the water storage capacity of the water storage tank 3 or the water storage tank 4 is increased at a constant speed. The discharge in municipal pipe network end inlet tube 1 roughly floats in a stable interval, and the flow of 5 interior waters of a water pipe is not more than the one-third of minimum discharge in municipal pipe network end inlet tube 1 when guaranteeing normal water supply to avoid producing too much influence to the water supply of user's pipe network end outlet pipe 2. Therefore, when the water consumption is urgent and the water flow of the water inlet pipe 1 at the municipal pipe network end is reduced, the throttle valve 8 on the first water pipe 5 does not need to be additionally adjusted. Only when municipal pipe network end inlet tube 1 stops supplying water completely, just need close choke valve 8 on a water pipe 5, prevent that the water in storage water tank 3 or the cistern 4 from suck-back to in municipal pipe network end inlet tube 1.
The water distribution pipe further comprises a second water pipe 6, the water inlet end of the second water pipe 6 is communicated to the municipal pipe network end water inlet pipe 1, and the water outlet end of the second water pipe 6 is communicated to the user pipe network end water outlet pipe 2.

The water storage tank 3 is also provided with a second water outlet 14, and the second water outlet 14 is communicated to the water outlet pipe 2 at the end of the user pipe network. During normal water supply, mutual independence between storage water tank 3 and user pipe network end outlet pipe 2, consequently be provided with gate valve 7 on the pipeline between No. two delivery ports 14 and user pipe network end outlet pipe 2 in this embodiment. Under the normal water supply condition, the gate valve 7 is closed, and the stored water in the water storage tank 3 can not flow to the water outlet pipe 2 at the end of the user pipe network. When the water is cut off emergently, the gate valve 7 is opened, and the water in the water storage tank 3 can flow to the water outlet pipe 2 at the end of the user pipe network along the pipeline between the second water outlet 14 and the water outlet pipe 2 at the end of the user pipe network, so as to supply the water to the user emergently. If the water supply amount of the municipal pipe network end water inlet pipe 1 is small, whether the gate valve 7 is opened or not is determined according to actual conditions.
Preferably, the second water pipe 6 is provided with a throttle valve 8. When the water is normally supplied, the throttle valve 8 on the second water pipe 6 is adjusted, so that the water flow in the second water pipe 6 is larger. If municipal pipe network end inlet tube 1 water supply quantity undersize or stop supplying water, then close choke valve 8 on No. two water pipes 6, open the gate valve 7 between No. two delivery ports 14 and user pipe network end outlet pipe 2, make the water in the storage water tank 3 inhale to user pipe network end outlet pipe 2, avoid the water in the storage water tank 3 to suck back to municipal pipe network end inlet tube 1 via No. two water pipes 6.
Preferably, the box-type non-negative-pressure community water supply system in this embodiment further includes a collecting pipe 9, the water outlet end of the second water pipe 6 and the second water outlet 14 are communicated to the user pipe network end water outlet pipe 2 through the collecting pipe 9, and the collecting pipe 9 is provided with a proportional control valve 10. Its aim at is to municipal pipe network end inlet tube 1 under the volume water supply condition supply water regulation, and when the discharge that municipal pipe network end inlet tube 1 provided was not big also not small, then open the gate valve 7 between No. two delivery ports 14 and user pipe network end outlet pipe 2 and the choke valve 8 on No. two water pipe 6 simultaneously, adjust the water proportion that gets into user pipe network end outlet pipe 2 from storage water tank 3 and from No. two water pipe 6 through proportion control valve 10 for storage water tank 3 supplements as a water source.
Considering that the long-term water storage of the water storage tank 4 can cause certain waste, and long-term water cut-off can usually be notified in advance, therefore only need receive long-term water cut-off notify when again to the water storage tank 4 impound can, only need to impound the storage water tank 3 at ordinary times, if the storage water tank 3 holds full then close the choke valve 8 on the water pipe 5 can. For this reason, the third water pipe 11 in this embodiment is also provided with a gate valve 7. Before receiving the long-term water cut-off notice, the gate valve 7 on the third water pipe 11 is closed, and only the water storage tank 3 is stored as an emergency water source for short-term water cut-off. Store up storage water tank 3 as early as possible and be full, reduce the feedback flow to municipal pipe network end inlet tube 1, reduce the influence to user's pipe network end outlet pipe 2. When receiving the long-term water supply stopping notification, the gate valve 7 on the third water pipe 11 is opened, and the water in the first water pipe 5 is stored into the reservoir 4 through the third water pipe 11 for accumulation.
