DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 In an embodiment of the utility model, a multifunctional water supply and drainage pipeline includes a main water supply and drainage pipeline 1 and a backup water supply and drainage pipeline 2. The backup water supply and drainage pipeline 2 is arranged on one side of the main water supply and drainage pipeline 1. One end of the backup water supply and drainage pipeline 2 is connected to a three-way valve 3 installed on the main water supply and drainage pipeline 1, and the other end of the backup water supply and drainage pipeline 2 is welded to the main water supply and drainage pipeline 1. A first filter 4 and a second filter 5 are respectively installed on the main water supply and drainage pipeline 1 and the backup water supply and drainage pipeline 2.

[0022] See also Figure 2, a water baffle 6 is arranged in the main water supply and drainage pipeline 1, and a torsion spring pin shaft 7 is installed at one end of the water baffle 6. The torsion spring pin shaft 7 includes a pin shaft and a torsion spring. The water baffle 6 can rotate relative to the pin shaft. The torsion spring is sleeved on the pin shaft and the two ends are respectively fixedly connected to the pin shaft and the water baffle 6. In the natural state, the water baffle 6 blocks the outlet of the main water supply and drainage pipeline 1 under the action of the torsion spring. The water baffle 6 is hinged to the inner wall of the main water supply and drainage pipeline 1 through the torsion spring pin shaft 7. When water flows through the main water supply and drainage pipeline 1, the water flow will flush the water baffle 6 open, and the water baffle 6 will It is pressed against one side of the main water supply and drainage pipe 1 to block the outlet of the backup water supply and drainage pipe 2 to prevent water from flowing back into the backup water supply and drainage pipe 2. When the main water supply and drainage pipe 1 is closed and the backup water supply and drainage pipe 2 is opened, the water baffle plate 6 will automatically reset under the drive of the torsion spring pin shaft 7, blocking the outlet of the main water supply and drainage pipe 1 to prevent water discharged from the backup water supply and drainage pipe 2 from flowing back into the main water supply and drainage pipe 1. This makes it convenient for personnel to replace, take out, clean or replace the filter mesh cylinder 10 in the first filter 4 or the second filter 5.

[0023] See also Figure 4 An upper insulation pad 14 and a lower insulation pad 15 are installed on the main water supply and drainage pipe 1 and the backup water supply and drainage pipe 2. The upper insulation pad 14 and the lower insulation pad 15 are wrapped around the water supply and drainage pipe in an arc shape, so that the pipe insulation performance is better and the water in the pipe is prevented from freezing when used in winter.

[0024] See also Figure 3 , the first filter 4 and the second filter 5 both include a straight tube body 8, an oblique tube body 9, a filter screen cartridge 10, an end cap 11 and a screw 13. The bottom of the straight tube body 8 is provided with an oblique tube body 9, and the bottom of the oblique tube body 9 is provided with a filter screen cartridge 10. The filter screen cartridge 10 is obliquely inserted between the straight tube body 8 and the oblique tube body 9. An end cap 11 is installed at the bottom of the filter screen cartridge 10. Screws 13 are installed on both sides of the end cap 11. The screws 13 are threadedly connected with the screw holes corresponding to the bottom end of the oblique tube body 9. Flange connections are adopted between the two ends of the first filter 4 and the main water supply and drainage pipeline 1, and between the two ends of the second filter 5 and the spare water supply and drainage pipeline 2. A sealing ring 12 is provided between the end cap 11 and the oblique tube body 9. The setting of the sealing ring 12 can play a sealing role between the end cap 11 and the oblique tube body 9 to avoid water leakage. The top circle of the filter screen cartridge 10 is sealed and connected with the straight tube body 8. The top end of the filter screen cartridge 10 is inclined toward the direction of water flow. Such a design can reduce the obstruction of the filter screen cartridge 10 to the water flow, so that the water flow is smoother.

[0025] The working principle of the utility model is:

[0026] When water flows through the main water supply and drainage pipe 1, the first filter 4 installed in the main water supply and drainage pipe 1 will intercept impurities in the water flow, and the intercepted impurities are stored in the filter mesh cylinder 10. When too many impurities accumulate in the first filter 4, the personnel first close the channel leading to the main water supply and drainage pipe 1 through the three-way valve 3 and open the backup water supply and drainage pipe 2 at the same time. After the water flows from the main water supply and drainage pipe 1 into the backup water supply and drainage pipe 2, it is filtered by the second filter 5 installed on the backup water supply and drainage pipe 2 and then flows into the main water supply and drainage pipe 1 again. In this way, the normal flow of water can be guaranteed without the need for shutdown operation.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
