Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Fig. 1, Fig. 3 and Fig. 4, an embodiment of the present utility model: comprises water storage tank 1, and the cross section of water storage tank is circular or square; The water inlet pipe 2, the water inlet pipe 2 is also provided with a water inlet check valve 3 and a hydraulic pressure sensor 4 and the water inlet check valve 3 is located on the side close to the water storage tank 1; the bottom of the water storage tank 1 is provided with a Connect the water outlet pipe 5 of the faucet, the water outlet pipe 5 is also provided with a water outlet check valve 6 and a water flow sensor 7 and the water outlet check valve 6 is arranged on the side close to the water storage tank 1; the top of the water storage tank 1 is provided with an air inlet pipe 8 and an air pressure pump 10, the air inlet of the air intake pipe 8 is connected to the air outlet of the air pressure pump 10, and an air intake check valve 9 is also provided on the air intake pipe 8; an indicator light L is installed on the outer surface of the water storage tank 1 , and the indicator light L is connected in series with the normally open contact S1 of the water pressure sensor 4 and connected to both ends of the 220V AC power supply, and the air pressure pump 10 is connected in series with the normally open contact S2 of the water flow sensor 7 and connected to the indicator light both ends of the L. The outer surface of the water storage tank 1 is provided with a vertical, transparent water level window 11 with a water level line. Through the water level window 11, the height of the water level in the water storage tank 1 can be clearly seen from the outside.

In the utility model, the volume of the water storage tank 1 is about 200L-300L, which is the main body of the emergency water supply system. During the normal water supply of the municipal water supply system, tap water flows out from the outlet pipe 5 through the water storage tank 1 through the water inlet pipe 2 with normal water pressure.

The water pressure sensor 4 is placed on the water inlet pipe 2 and close to the side of the municipal water supply system. When the emergency water supply system continues to supply water, the water pressure sensor 4 generates water pressure within a certain range; The water flow in 2 gradually slows down, the water pressure drops until it is 0, the normally open contact S1 of the water pressure sensor 4 is closed, and the indicator light L is on. And when the water is just cut off, the air pressure in the water storage tank 1 is greater than the water supply system air pressure, and the water flow backflow may occur. The water inlet check valve 3 on the water inlet pipe 2 effectively prevents the water flow backflow when the water is just cut off. At this time, there is full water in the water storage tank 1 for emergency use, and opening the air pressure pump 10 can increase the air pressure in the water storage tank 1 to provide normal water pressure for the water system. The intake check valve 9 is installed on the intake pipe 8, even if the air pressure pump 10 does not work, it can ensure that the gas can only go in and out. The presence of the water inlet check valve 3 , the water outlet check valve 6 and the intake check valve 9 ensures the negative pressure balance in the water storage tank 1 .

The water flow sensor 7 is placed on the water outlet pipe 5 and close to the side of the faucet. The air pressure pump 10 is installed on the top of the water storage tank 1. The working state of the air pressure pump 10 is controlled by the water pressure sensor 4 and the water flow sensor 7. The air pressure pump 1 can automatically Open to ensure the normal effect of water pressure at any time. When there is no water pressure at the water pressure sensor 4 and there is water flowing in the water outlet pipe 5, that is, water, the normally open contact S2 of the water flow sensor 7 is closed, and the air pressure pump 10 is powered on to increase the air pressure for the water storage tank 1, so that the water storage tank 1 The water in the tank is the same as the normal water supply pressure of the municipal water supply system, so that the water storage tank 1 can be normally supplied no matter where it is placed. When there is no water flow in the outlet pipe 5, that is, when there is no water or the tap water in the water storage tank 1 is used up, the normally open contact S2 of the water flow sensor 7 is disconnected, and the air pressure pump 10 stops working. Since the water cut-off time is less than the normal water supply time, the air pressure pump 10 is only powered on when the water is cut off, which greatly improves the service life of the emergency water supply system. In order to ensure the effectiveness of the work of the pneumatic pump 10, a delayer can be installed.

Further, a vertical window is provided on the outer surface of the water storage tank 1, and a filter box is provided on the inner surface of the water level window 11, and the filter box is inserted in the window and the inner end of the water inlet pipe 2 is directly inserted into the top of the filter box; Between the window 11 and the window is a sealed connection. The filter box is a pluggable structure similar to a drawer. The water in the water inlet pipe 2 is first discharged into the filter box, and then used after being filtered by the filter box; the filter box and the water level window 11 are pulled out from the window, and the filter can be cleaned conveniently. Tank and storage tank 1.

As shown in Figure 2, another embodiment of the utility model: the water storage tank 1 is made of plastic material, and the inner side wall of the water storage tank 1 is provided with a longitudinal inner slideway, and an inner magnetic block is provided for sliding in the inner slideway, and the inner magnet A floating ball is fixed on the outer side of the block, and the floating ball makes the inner magnetic block always float on the water surface; a longitudinal outer slideway 12 is provided on the outer surface of the water storage tank 1 opposite to the inner slideway, and the outer slideway 12 slides An outer magnetic block is provided, and the indicator light L is installed on the outer side of the outer magnetic block. At night or when the light is dark, it is difficult to see the water level in the water storage tank 1 through the water level line 11 . At this time, as the water level in the water storage tank 1 drops during emergency water use, the floating ball and the inner magnetic block will slide along with the water level drop in the inner slideway, and the inner magnetic block will attract the outer magnetic block in the outer slideway 12 together. slide down, and the lit indicator light L is installed on the outer magnetic block, so by looking at the indicator light L, you can clearly see its height on the water storage tank 1 even in the dark, and then know the water level in the water storage tank 1 high and low.

The above description is only proposed as an implementable technical solution of the utility model, not as a single restriction on the technical solution itself.
