Example one

As shown in fig. 1, the emergency water supply device includes a water storage tank 1, a pressure controller 2, an electromagnetic valve 3, a first check valve 4, a water pump 5, a second check valve 6, and a third check valve 7.

The water storage tank 1 is a closed stainless steel container, preferably having a cylindrical structure, so that more water can be stored in a limited space. The water storage tank 1 is provided with a water inlet which is positioned at the upper part of the water storage tank 1 and a water outlet which is positioned at the bottom of the water storage tank 1.

The water inlet of the water storage tank 1 is connected with the water outlet of the first one-way valve 4 through a pipeline. The first check valve 4 may be a check valve of a common structure, or may be a check valve with a pressure relief function, for example, a pressure relief check valve connected to a water inlet of an electric water heater. This has the advantage that when the pressure in the water storage tank 1 is too high, the pressure can be released through the first check valve 4 with the pressure release function, so as to prevent accidents.

The water inlet of first check valve 4 passes through the pipeline and is connected with 3 one end of solenoid valve, still fixedly on the water inlet pipeline of solenoid valve 3 is provided with pressure controller 2 for detect and acquire the pressure in the water inlet pipeline of solenoid valve 3. Specifically, the other end of the electromagnetic valve 3 is connected to one end of the pressure controller 2 through a pipe. Wherein the pressure controller is connected with the pipeline through a tee joint or directly welded on the pipeline.

The electromagnetic valve 3 is a common normally open type electromagnetic valve, that is, when the coil of the electromagnetic valve is not electrified, the electromagnetic valve is opened, and water flow can freely flow through the electromagnetic valve. When the coil of the electromagnetic valve is electrified, the electromagnetic valve is closed to prevent water from flowing through.

The pressure controller 2 adopts a PC-2 pressure controller special for towerless water supply in east China sea, is provided with a group contact, can adjust the action pressure value by adjusting the pressure of a spring, and can meet the requirement of the invention. As shown in fig. 2, two sets of contacts of the pressure controller 2 are respectively connected with the storage battery, the coil of the electromagnetic valve 3 and the motor of the water pump 5, specifically, the first set of contacts connects the motor of the water pump 5 in series with the storage battery, and the second set of contacts connects the coil of the electromagnetic valve 3 in series with the storage battery.

The water outlet of the water storage tank 1 is connected with the water inlet of the water pump 5 through a pipeline, and the water outlet of the water pump 5 is connected with the water inlet of the second one-way valve 6 through a pipeline. The water pump 5 used here should be configured with a water flow sensing switch to prevent idling, such as a booster pump with idling prevention, in order to prevent idling. In addition, the second check valve 6 is a common check valve and has no special requirement.

In order to keep the interior of the water storage tank 1 clean, a first water tap 16 may be connected between the water outlet of the water pump 5 and the water inlet of the second check valve 6, and the first water tap 16 may be connected to an electric appliance such as a washing machine, and the water in the water storage tank 1 may be discharged through the first water tap 16 to prevent deposition thereof.

The water outlet of the second one-way valve 6 is respectively connected with the other end of the pressure controller 2, the rest of the second water taps 17 in the house and the water outlet of the third one-way valve 7 through pipelines.

The third check valve 7 is also a normal check valve and has no special requirement. The water inlet of the third one-way valve 7 is connected with the water outlet end of a main water inlet valve 14 in a house, and the water inlet end of the main water inlet valve 14 is connected into the main pipe.

When the tap water is normally supplied, the pressure controller 2 senses the normal water pressure and rapidly acts, the normally closed contact is disconnected, and the circuit of the electromagnetic valve and the water pump motor is cut off. Tap water sequentially enters the water storage tank 1 from the main water inlet valve 14, the third one-way valve 7, the pressure controller 2, the electromagnetic valve 3 and the first one-way valve 4, so that the function of automatic water storage is achieved. Because the water storage tank 1 is a closed container, when the pressure of the water storage tank 1 is balanced with the pressure of a tap water pipeline, water flow can not flow any more.

When the outside is cut off and someone opens the faucet, the pressure controller 2 senses the pressure abnormity, when the pressure is lower than the set value, the contact of the pressure controller 2 is connected with the coil of the storage battery and the electromagnetic valve 3 and the loop of the storage battery and the motor of the water pump 5, so that the water pump 5 is started to pump the water in the water storage tank 1 to provide water for a user, and meanwhile, the electromagnetic valve 3 is closed to prevent the water from continuously entering the water storage tank 1 along the pipeline to cause circulation.

In practical application, it is found that if the pipe diameter of the water pipe connected to the water inlet of the water storage tank 1 is too large, sudden pressure drop is easily caused when the electromagnetic valve 3 acts, so as to cause malfunction of the pressure controller 2, and therefore, the pipe diameter of the water pipe at the water inlet of the water storage tank 1 can be properly reduced, and preferably, the pipe diameter of the water pipe at the water inlet of the water storage tank 1 is smaller than the pipe diameter of the water outlet of the pressure controller 2. Of course, this problem can also be solved by choosing a pressure controller 2 that is less sensitive to pressure variations.

The embodiment only needs the water storage tank 1, the pressure controller 2, the electromagnetic valve 3, the first one-way valve 4, the water pump 5, the second one-way valve 6 and the third one-way valve 7 to add an automatic water storage and automatic water supply function on the basis of the existing household pipeline, and the household pipeline has the advantages of simple structure, easiness in installation and convenience in use.

Example two

As shown in fig. 3, on the basis of the first embodiment, in order to facilitate the maintenance and replacement of the device, a first valve 9 is directly connected between the water outlet of the water storage tank 1 and the water inlet of the water pump 5; a second valve 12 is connected to the outlet end of the second check valve 6 and a third valve 13 is connected between the second faucet 17 and the inlet of the pressure controller 2.

In order to facilitate observation of the pressure conditions of the water inlet and the water outlet of the water pump 5, a first pressure gauge 10 is connected to the water inlet of the water pump 5, and a second pressure gauge 11 is connected to the water outlet of the water pump 5.

In order to facilitate the user to know whether tap water or standby water is currently used, a flow detection indicating device 15 is connected between the water outlet end of the second check valve 6 and the second valve 12. The flow detection indicating device 15 is a common flow meter, and can indicate an alarm when water flows through the flow meter, so that a user is informed that standby water is used at present and the use is saved.

In particular, a fourth check valve 8 is installed on the first check valve 4 and the pipe of the water inlet of the water storage tank 1. The water inlet end of the fourth one-way valve 8 is connected with the atmosphere, and the water outlet end is connected to the pipeline and used for supplying air to the pipeline. In practice, it is found that when the standby water is used, because the water pump 5 pumps out the water in the water storage tank 1, a negative pressure is formed in the water storage tank 1, which influences the outflow of the water from the water storage tank 1, and therefore, a fourth check valve 8 with a water inlet end communicated with the atmosphere is specially arranged, and when the water pump 5 works, the air is supplemented into the water storage tank 1 from the fourth check valve 8 to keep balance. In order to ensure the cleanness of the inside of the water storage tank 1 and prevent foreign matters from entering the water storage tank from the fourth check valve 8, a filter may be provided at the water inlet end of the fourth check valve 8. In addition, the fourth check valve 8 should be installed at a position lower than the water inlet position of the water storage tank 1 so that water is normally present in the connection pipe between the water inlet of the water storage tank 1 and the fourth check valve 8, thereby preventing air of the water storage tank 1 from leaking from the fourth check valve 8.

This embodiment has increased a plurality of manual valves, manometer and fourth check valve 8 backs on the basis of embodiment one, and the more convenient to overhaul changes the device, is convenient for observe water pressure and effectively solves the problem that the negative pressure influences rivers and flows in leading to appearing in the cistern because of the effect of water pump.
