Detailed ways

Below in conjunction with accompanying drawing and through embodiment the utility model is further described.

Example:

Referring to Fig. 1, the utility model comprises a sealed tank body 1, a leg 2, a safety valve 3, a sewage valve 4, an inlet pipe 5, an outlet pipe 6, a control switch 7, a pressure gauge 8 and a one-way valve 9, wherein the leg 2 is welded on The lower part of the sealed tank body 1, of course, the legs 2 of the present utility model can also be fixed on the sealed tank body 1 by other means, such as threaded connection and the like. Sewage valve 4 is installed in the bottom of sealed tank body 1, and safety valve 3, control switch 7 and pressure gauge 8 are all fixed on the top of sealed tank body 1 by thread, certainly safety valve 3, control switch 7 and The pressure gauge 8 can also be fixed on the sealed tank body 1 by means of welding or the like. Both the water inlet pipe 5 and the water outlet pipe 6 are fixed on the sealed tank body 1 by threads, and the one-way valve 9 is fixed on the water inlet pipe 5 by threads.

The sealed tank body 1 in the utility model is a sealed type, that is, when the safety valve 3 and the sewage valve 4 are closed, the sealed tank body 1 communicates with the outside only by the water inlet pipe 5 and the water outlet pipe 6, that is to say, the sealed tank body All other parts in the body 1 are closed, so that the inside of the sealed tank body 1 can withstand a certain pressure. The inside of the sealed tank body 1 of the utility model is provided with an inner wall layer, which is made of high-density polyethylene; the outside of the sealed tank body 1 is also provided with a topcoat layer, and the topcoat layer is made of polyester material. The inner wall layer and the finish paint layer are added in the sealed tank body 1, so that the structure of the sealed tank body 1 is firmer and corrosion-resistant, prolonging the service life of the utility model.

When using the utility model, connect the water inlet pipe 5 to the water pump, connect the water outlet pipe 6 to the user's water terminal, first start the water pump connected to the water inlet pipe 5, and drive the water in the external pipe network into the sealed tank through the water pump In the body 1, when water enters the sealed tank body 1 from the water inlet pipe 5 at this time, the one-way valve 3 is opened, and the external water is pressed into the sealed tank body 1 by the water pump. Since the volume of the sealed tank body 1 is fixed, before filling the sealed tank body 1 with water, the sealed tank body 1 is filled with air, and when water enters the sealed tank body 1, the air in the sealed tank body 1 is compressed , as the external water is continuously pressed in, the volume of water in the sealed tank body 1 increases, so that the volume of the air in the sealed tank body 1 becomes smaller, that is, the air in the sealed tank body 1 is continuously compressed, so that Just make the pressure in the sealed tank body 1 constantly increase, and the reading of the pressure gauge 8 constantly increases. When the water in the sealed tank 1 reaches a certain liquid level, the air in the sealed tank 1 is compressed to a certain degree, and the reading in the pressure gauge 8 reaches the upper limit setting value, the control switch 7 disconnects the power supply, and the water pump Stop working, now the one-way valve 9 installed on the water outlet pipe 6 is closed, that is to say, the water in the sealed tank body 1 cannot flow to the water outlet pipe 6 from the sealed tank body 1, so that the sealed tank body 1 is filled with water The process is complete.

At this time, the pressure in the sealed tank body 1 is relatively high, and the user only needs to open the water terminal, and the water in the sealed tank body 1 is pressed onto the water terminal, and as the water in the sealed tank body 1 is continuously used , the stored water in the sealed tank 1 gradually decreases, that is, the volume of water in the sealed tank 1 becomes smaller, and the volume of the air in the sealed tank 1 increases accordingly, so that the pressure in the sealed tank 1 is also corresponding Reduced, when the pressure in the sealed tank 1 drops to the lower limit set value of the pressure gauge 8, the control switch 7 is powered on, the water pump starts again, and the external water is transported into the sealed tank 1 by the water pump until When the pressure in the sealed tank body 1 reaches the upper limit setting value of the pressure gauge 8, the control switch 7 cuts off the power supply, and the water pump stops working. The utility model works in such a repeated cycle that the utility model can continuously supply water and run fully automatically. Thus it can be seen that the utility model utilizes the pressure of air rebound after compression to pressurize the inside of the sealed tank body 1 to achieve the purpose of water supply. In the utility model, when the pressure in the sealed tank body 1 reaches the upper limit setting value of the pressure gauge 8, the control switch 7 disconnects the power supply, and the water pump stops working; During setting value, control switch 7 just connects power supply, and water pump begins to work, and these are prior art, no longer describe in detail here.

When the utility model encounters a water failure in the external pipeline or a power failure in the external power grid, as long as there is a certain amount of water in the sealed tank body 1, and the pressure in the sealed tank body 1 is above the lower limit set value of the pressure gauge 8 It can supply water normally and is less affected by external conditions, so it is very convenient to use.

In addition, it should be noted that all equivalent or simple changes made according to the structure, features and principles described in the utility model patent concept are included in the protection scope of the utility model patent.
