[0020] In order to make the description clearer, the present application is further described in combination with the drawings.

[0021] The utility model provides a kind of water treatment pressure tank of stabilized voltage of easy maintenance, including tank body 4, it is characterized by: the water inlet pipe 3 is fixedly arranged on one side of the tank body 4, the water outlet pipe 8 is fixedly arranged in the lower center position of the tank body 4, the rubber diaphragm 7 is arranged inside the tank body 4, the cover body 6 is arranged on the upper portion of the tank body 4, the air inlet pipe 1 is fixedly arranged in the upper center position of the cover body 6, the tank body 4 is fixedly arranged with the supporting leg 5 in lower portion symmetry.

[0022] Further, the rubber diaphragm 7 is located above the water inlet pipe 3, in natural state, the rubber diaphragm 7 is in drooping state.

[0023] Further, the carrier ring 11 is fixedly arranged inside the tank body 4, the upper pressing ring 9 and the lower pressing ring 10 are arranged above the carrier ring 11, the pressure bearing part 14 is arranged on the outer edge of the rubber diaphragm 7, the pressure bearing part 14 is located between the upper pressing ring 9 and the lower pressing ring 10, the bolt 12 is arranged above the carrier ring 11, and the bolt 12 is threadedly connected with the upper pressing ring 9, the pressure bearing part 14, the lower pressing ring 10 and the carrier ring 11.

[0024] Further, the sealing gasket 13 is arranged on the upper portion of the carrier ring 11, and the sealing gasket 13 is attached to the lower pressing ring 10 and the carrier ring 11.

[0025] Further, the lower inner edge of the upper pressing ring 9 and the upper inner edge of the lower pressing ring 10 are both in the shape of a rounded corner.

[0026] Further, the cover body 6 is threadedly connected with the tank body 4.

[0027] Further, the pressure control switch 2 is fixedly arranged on the front portion of the tank body 4.

[0028] The working principle of the water treatment pressure tank of stabilized voltage of easy maintenance is as follows: the water inlet pipe 3 is connected with the upper water source, the water outlet pipe 8 is connected with the lower pipeline, and the air inlet pipe 1 is connected with the air source; the valve at the position of the air inlet pipe 1 is opened, the space above the rubber diaphragm 7 in the tank body 4 is inflated, until the air pressure in the space reaches the required value; water is injected below the rubber diaphragm 7 through the water inlet pipe 3, the rubber diaphragm 7 is lifted up by the water, the gas above the rubber diaphragm 7 is squeezed and the air pressure above the rubber diaphragm 7 is increased, until the upper limit of the air pressure is reached, the valve at the position of the air inlet pipe 1 is closed and the water injection is stopped by the pressure control switch 2; as the water in the lower pipeline is used, the water level below the rubber diaphragm 7 decreases, the rubber diaphragm 7 falls back, the air pressure above the rubber diaphragm 7 decreases, until the lower limit of the air pressure is reached, the valve at the position of the air inlet pipe 1 is opened and the water injection is restarted by the pressure control switch 2, and the above process is repeated; when the rubber diaphragm 7 is worn out due to frequent lifting and falling, the above process cannot be smoothly performed, at this time, the user only needs to remove the cover body 6 and the bolt 12 to replace the rubber diaphragm 7, and the rubber diaphragm 7 can be continuously used after the bolt 12 and the cover body 6 are reset.
