FIG. 2 is an installation schematic view of a return water sluicing storage pipe and a supply water sluicing storage pipe.
The water supply system comprises a directly-buried water return pipe 1, a directly-buried water supply pipe 2, a first reinforcing tee joint 3, a second reinforcing tee joint 4, a water return water drain pipe 5, a water supply water drain pipe 6, a second directly-buried reducer pipe 7, a water return water drain well 8, a water supply water drain well 9, a pressure relief pipe 10, a pressure relief ball valve 11, a second flange 12, a first flange 13, a water return water drain storage pipe 14 and a water supply drain storage pipe 15.
Detailed Description
As shown in the attached drawings 1 to 2, the directly-buried hot water pipe network water drainage device comprises a directly-buried water return pipe and a directly-buried water supply pipe, wherein the directly-buried water return pipe is connected with a water return drainage storage pipe through a water return drainage pipe, a water return drainage well chamber is connected above the water return drainage storage pipe through a first flange, the directly-buried water supply pipe is connected with a water supply drainage storage pipe through a water supply drainage pipe, and the water supply drainage pipe is connected with the water supply drainage well chamber through a second flange.
And the upper ends of the water supply and water drain storage pipe and the water return and water drain storage pipe are respectively provided with a pressure relief pipe, and the pressure relief pipe is provided with a pressure relief ball valve.
The directly-buried return water pipe is through first enhancement tee junction return water outlet pipe, and the directly-buried water supply pipe is strengthened tee junction water supply outlet pipe through the second, and water supply outlet storage tube and return water outlet storage tube are DN400 prefabricated directly-buried insulating tube and stand in soil, and the top is sealed with the flange, is close to the top and draws a DN100 prefabricated directly-buried insulating tube as the pressure release pipe, sets up the pressure release ball valve on the pipeline, and the valve is opened and is led rivers to sewer or rainwater well department.
And cushion layers are arranged below the water supply and water drainage well chamber and the water return and water drainage well chamber, the water supply and water drainage well chamber and the water return and water drainage well chamber are circular wells with the inner diameter of about 1m and the height of about 0.5m, and are positioned on the cushion layers, and the sealing flange at the top of the drainage storage pipe and the pressure relief pipe are contained.
The backwater sluicing pipe is connected with a backwater sluicing storage pipe through a first directly-buried reducing pipe, and the water supply sluicing pipe is connected with a water supply sluicing storage pipe through a second directly-buried reducing pipe.
The working process of the invention is as follows: when the heat supply pipe network system runs in a test mode, the first flange and the second flange need to be closed tightly, the pressure relief ball valve is opened to release air, and when water flows out of the pressure relief pipe, the pressure relief ball valve is closed, so that the hot water pipe network, the return water drain storage pipe and the water supply drain storage pipe form a closed system; when the heat supply pipe network needs to be maintained, the pressure relief ball valve must be opened firstly to relieve pressure, and then the first flange and the second flange are opened to pump water by using the water suction pump.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be considered as the protection scope of the present invention.
