The working principle is as follows: when rivers pass through fourth pipeline 6 from the water supply network, water can get into third pipeline 5, then passes the deceleration device, carries out the deceleration through the deceleration device to rivers, then enters into the inside of water tank 3 through second pipeline 4, is saved by water tank 3, then when needs water, water pump 1 can take out the inside water of water tank 3, and the water of taking out enters into every family through first pipeline 2, provides the water for the user.

When the water flow passes through the deceleration device, firstly, the water passes through the fifth pipeline 9 and then impacts the second baffle 17, then the water flow splashes to the inside of the first deceleration box 10, then enters the inside of the second deceleration box 12 through the circular hole 19 and the first filtering hole 20, and after the water enters the inside of the second deceleration box 12, the water flows into the inside of the sixth pipeline 13 along the second filtering hole 26 and the third filtering hole 32 and the gap between the second filtering hole 26 and the third filtering hole 32, and then flows into the inside of the water tank 3 through the sixth pipeline 13.

When rivers are great, can rotate first axis of rotation 14, make first axis of rotation 14 drive connecting plate 15 and rotate, connecting plate 15 rotates and drives second baffle 17 and rotate, when the lateral wall of limiting plate 22 and the lateral wall laminating of backup pad 16, thereby make second baffle 17 and the laminating of third baffle 18, make the water that strikes on the second baffle 17 splash to the inside of first reduction case 10, then rivers can enter into the inside of second reduction case 12 through first filtration hole 20 and circular port 19 of crossing.

When entering the interior of the second reduction box 12, the water flows into the upper portion of the fifth baffle 25, then passes through the fifth baffle 25 along the second filtering holes 26, then enters the interlayer between the fifth baffle 25 and the seventh baffle 31, and finally flows through the seventh baffle 31 via the third filtering holes 32, and then enters the interior of the water tank 3 along the sixth pipeline 13.

When using for a long time, because rivers impact on the fifth baffle 25, can exert pressure to fifth baffle 25, thereby extrude spring 34, make spring 34 take place elastic deformation, be in under the pressure effect for a long time, the elasticity of spring 34 can reduce, thereby can rotate second axis of rotation 41, make second axis of rotation 41 drive second conical gear 40 and rotate, second conical gear 40 rotates and drives first conical gear 39 and rotate, first conical gear 39 rotates and drives threaded sleeve 38 and rotate, threaded sleeve 38 rotates and drives threaded rod 37 and upwards slide, threaded rod 37 upwards slides and can drive annular ring 44 and upwards slide at the inner wall of spout 28, thereby promote slider 27 and fifth baffle 25 and upwards slide, make spring 34 open, thereby can resume the elasticity of spring 34.

After long-term use, because the second baffle 17 is directly impacted by water in the running water network, the second baffle 17 is easily damaged, when the second baffle 17 is damaged, because the second baffle 17 does not block the water, the water flow can directly pass through the circular hole 19 to impact the top end of the fourth baffle 23, because the water pressure does not pass through the deceleration of the second deceleration component, the flow rate of the water is too high, the generated pressure is large, the fourth baffle 23 can be extruded, the fourth baffle 23 can extrude the fifth baffle 25, the fifth baffle 25 can extrude the spring 34, the spring 34 is elastically deformed, so that the fifth baffle 25 slides, the sliding of the fifth baffle 25 can reduce the gap between the fifth baffle 25 and the second filtering hole 26, so that the deceleration effect on the water flow can be achieved, and meanwhile, when the fifth baffle 25 slides, the sliding block 27 can be contacted with the switch 42, so as to cause the buzzer 43 to give an alarm, reminding the worker that the second baffle 17 is damaged and the second baffle 17 needs to be maintained.

When one of the speed reduction devices needs to be maintained, the valve 7 can be rotated, so that water flows through the other speed reduction device and enters the water tank 3, and the maintenance of the speed reduction device is facilitated.
