Drawings
FIG. 1 is a schematic structural view of the present invention,
the device comprises a water storage tank 1, a water storage tank 11, an air cavity 12, a water storage cavity 2, an electric cabinet 3, a water inlet 31, a water inlet switch 4, a water outlet 41, a water outlet switch 5, a liquid level meter 6, an elastic diaphragm 7, a micro-pressure safety valve 8 and an exhaust port.
Detailed Description
The utility model will be further illustrated and understood by the following non-limiting examples.
As shown in figure 1, the utility model provides a diaphragm type normal pressure floating roof device, which comprises a water storage tank 1 and an electric cabinet 2, wherein an exhaust port 8 is arranged at the top of the water storage tank 1, a water inlet 3 and a water outlet 4 are respectively arranged at two sides of the bottom of the water storage tank 1, a water inlet switch 31 is arranged at the water inlet 3, a water outlet switch 41 is arranged at the water outlet 4, a liquid level meter 5 is vertically arranged on the inner wall of the water storage tank 1, the liquid level meter 5 is provided with a low water level L1 and a high water level L2, an elastic diaphragm 6 is fixedly arranged above the liquid level meter 5 in the water storage tank 1, the elastic diaphragm 6 is made of soft light materials, the elastic diaphragm 6 divides the water storage tank 1 into an air cavity 11 communicated with the exhaust port 8, a water storage cavity 12 communicated with the water inlet 3 and the water outlet 4, a safety port communicated with the water storage cavity 12 is also arranged at the top of the water storage tank 1, a micro-pressure safety valve 7 is arranged at the safety port, and the liquid level meter 5, The water inlet switch 31 and the water outlet switch 41 are electrically connected with the electric cabinet 2. The water inlet switch 31 is a water inlet electromagnetic valve or a water inlet pump, and the water outlet switch 41 is a water outlet electromagnetic valve or a water pump.
The working process of the utility model is as follows:
controlling water inflow: when the liquid level meter 5 detects that the liquid level is lower than L1, the electric cabinet 2 controls the water inlet electromagnetic valve or the water inlet pump to open water replenishing, the liquid level rises, the liquid is isolated from the outside atmosphere due to the action of the elastic diaphragm 6, the elastic diaphragm 6 floats on the surface of the liquid, and along with the rise of the liquid level, the gas in the air cavity 11 is discharged through the air outlet 8, and when the liquid rises to L2, the electric cabinet 2 controls the water inlet electromagnetic valve or the water inlet pump to stop, and the water inlet stops;
under normal conditions, the water level is kept between L1 and L2, in case the liquid level continues to rise due to failure of the electromagnetic valve and the like, pressure can be generated in the water storage cavity 12 due to the action of the elastic diaphragm 6, and when the pressure exceeds the micro-pressure safety valve 7, the micro-pressure safety valve 7 is automatically opened to drain water and release pressure;
controlling water outlet: when the electric cabinet 2 controls the water outlet electromagnetic valve or the water pumping pump to start and pump the liquid in the water storage cavity 12, the liquid level automatically descends, and meanwhile, the elastic diaphragm 6 also descends along with the liquid level under the action of gravity until the water outlet stops. The liquid of the container is not in contact with the atmosphere due to the barrier action of the elastic membrane 6.
To sum up, no matter the solution enters or flows out, because the action of the elastic diaphragm 6 is not contacted with the atmosphere, the damage of oxygen in the atmosphere and the like to the solution is effectively avoided, and the production and living needs are met. The elastic diaphragm 6, the liquid level meter 5, the water inlet switch 31, the water outlet switch 41 and the electric cabinet 2 can realize the normal-pressure sealed storage of liquid and the control of automatic liquid inlet and discharge.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
