Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.
Fig. 1 is a schematic view of a high-level elastic unit according to the present invention.
Referring to FIG. 1, a preferred embodiment of a high-level spring unit is shown, comprising
The pressure stabilizing tank 1, and the water inlet and outlet 11 of the pressure stabilizing tank 1 are connected with the top end of a municipal vertical pipe 10.
And the exhaust valve 2 are arranged at the water inlet and the water outlet 11 of the surge tank 1.
The air supply metering device is arranged at the bottom of the pressure stabilizing tank 1; the lower end surface of the air supply metering device is connected to the base 5 through a plurality of upright posts 4.
The inflation inlet 6, the inflation inlet 6 sets up in one side of surge tank 1.
The pressure sensor 7, the pressure sensor 7 is set up in one side of the inlet outlet 11; the pressure sensor 7 is connected to a pressure gauge 71.
The above is merely an example of the preferred embodiments of the present invention, and the embodiments and the protection scope of the present invention are not limited thereby.
Further, in a preferred embodiment, the air supply metering device includes a weighing device and a display device 32; the weighing device is arranged on the tray device 31, and the tray device 31 is arranged on the plurality of upright posts 4; the weighing device is electrically connected to the display device 32.
Further, in a preferred embodiment, the weighing device is provided with a piezoelectric transducer which converts the applied pressure directly into a weight.
Further, in a preferred embodiment, the inflation port 6 is provided with a solenoid valve, which is electrically connected to the weighing device and the pressure sensor 7. When the value measured by the weighing device is greater than the sum of the self weight of the tank body and the density of 0.6V water, the pressure stabilizing tank 1 is inflated by opening the electromagnetic valve.
Further, in a preferred embodiment, the pressure gauge 71 is disposed on the upper surface of the surge tank 1.
Further, in a preferred embodiment, the air supply metering device further comprises an alarm device; the alarm device is electrically connected with the weighing device.
In addition to the above embodiments, the present invention also has the following working method:
firstly, a rubber bag (not shown in the figure) is arranged in the pressure stabilizing tank 1, the expansion amount of the rubber bag is limited, so that a part of gas must be filled in advance to avoid the burst of the rubber bag; the pre-charging pressure is generally 0.4 times of the working pressure, and the volume of the pressure stabilizing tank 1 is V; the actual working pressure is assumed to be 0.1MPa and the top end of the riser is typically set.
In normal conditions, the internal volume of the pressure stabilizing tank 1 is V1, and the working pressure is 0.1 MPa; after the operation is finished, the internal gas volume of the surge tank 1 is V2 (equal to the volume V of the surge tank 1), and the working pressure is P2-0.04 MPa;
v1 is therefore 0.4V according to the law P1V 1-P2V 2;
calculating to obtain a compensation amount, namely the volume of the internal water storage is V-V1-0.6V;
the following can be obtained: the weight of the impounded water was 0.6V water density (weight of maximum impounded water).
Therefore, if the weight of the air supply metering device is measured by the weighing device to be greater than the sum of the self weight of the tank body and the density of 0.6V water, namely the pressure inside the pressure stabilizing tank 1 is reduced, the water inflow exceeds the water storage amount.
Therefore, the water inlet and outlet 11 is needed to be used for observing the water inlet pressure, if the water inlet pressure is kept at 0.1MPa for a long time, the internal pressure of the pressure stabilizing tank 1 is balanced, and whether the weight value measured by the weighing device is the sum of the self weight of the tank body and the density of 0.6V water or not is observed; if the weight is larger than the value, the surge tank 1 is inflated until the weight value measured by the weighing device is equal to the value.
The above is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, and it should be appreciated by those skilled in the art that various equivalent substitutions and obvious changes made in the specification and drawings should be included within the scope of the present invention.
