Background Art

The existing municipal pipe network and sewage inspection wells are mostly connected by dual pipes, one of which is the water inlet pipe and the other is the water outlet pipe. The two pipes are parallel to each other and operate independently of each other. Since the two pipes are independent of each other, both pipes can only realize one-way water delivery during water supply and drainage. Therefore, it is necessary to comprehensively consider the daily flow rate and cost investment during construction. It is impossible to use a high-power water pump, so it is impossible to meet the temporary large-flow water delivery demand. In addition, when a pipeline fails, it needs to be shut down for maintenance, which cannot meet the requirement of continuous normal operation under a fault state. The utility model provides a dual-channel storage and regulation pipeline system for a municipal sewage pipe network to solve the above problems.

The connecting pipeline 5 is connected between the water inlet pipeline 3 and the water outlet pipeline 4. As a common pipeline, no matter water is delivered from the sewage well 1 to the sewage storage tank 2 or from the sewage storage tank 2 to the sewage well 1, water is delivered through the connecting pipeline 5, which effectively saves construction costs. Moreover, two parallel pipelines can not only take into account different flow rates, but also will not affect the normal operation of the pipeline network when one of the connecting pipelines 5 fails.

In a specific embodiment of the utility model, the water inlet pipe 3 and the water outlet pipe 4 are connected between the sewage well 1 and the sewage storage tank 2, and two connecting pipes 5 are arranged in parallel between the water inlet pipe 3 and the water outlet pipe 4 to form two branches. Only one of the two connecting pipes 5 can be used, or they can be used at the same time; when delivering water, water is taken in from the water inlet of the water inlet pipe 3 connected to the sewage well 1 or the sewage storage tank 2, and flows into the water outlet pipe 4 through one or two connecting pipes 5, and then delivered to the relative sewage storage tank 2 or sewage well 1 through the water outlet on the water outlet pipe 4 to achieve water delivery; the two connecting pipes 5 arranged in parallel can cooperate in water delivery. When the flow rate is small, water delivery through one connecting pipe 5 can meet the demand. When the flow rate is large, the two connecting pipes 5 deliver water at the same time, thereby increasing the delivery volume per unit time and meeting different water delivery conditions; and the two connecting pipes 5 are arranged so that when one of them fails, it can still operate normally, and the normal water delivery is not affected when the fault is repaired.

Furthermore, the water flow direction of the one-way valve 55 is from the water inlet pipeline 3 to the water outlet pipeline 4 .

Preferably, the control valve 31 is an electric valve, and the water pump 52 is a self-priming pump.

Preferably, the opening of the valve is controlled according to the flow demand, and after the valve on one of the connecting pipes 5 is fully opened, the valve on the other connecting pipe 5 is opened to meet the water delivery demand of a larger flow rate. In addition, liquid level gauges can be set in the sewage well 1 and the sewage storage tank 2, and an automatic control system can be set to connect the valve and the water pump to realize automatic water delivery.

When the utility model is used, when water is delivered from the sewage well 1 to the sewage storage tank 2, the control valve 31 on the water inlet pipe 3 located on the side of the sewage well 1 and the control valve 31 on the water outlet pipe 4 located on the side of the sewage storage tank 2 are opened, the control valve 31 on the water inlet pipe 3 located on the side of the sewage storage tank 2 and the control valve 31 on the water outlet pipe 4 on the side of the sewage well 1 are closed, and the water inlet valve 51 and the water outlet valve 56 on one or two connecting pipes 5 are opened as needed, and the water pump 52 on the corresponding connecting pipe 5 is started to deliver water; when water is delivered from the sewage storage tank 2 to the sewage well 1, the valves on the water inlet pipe 3 and the water outlet pipe 4 are switched oppositely, and the operation of the connecting pipe 5 is the same.
