[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0018] like Figures 1-2 The illustrated low-pressure automatic drainage device's core function is to drain water without venting air under low-pressure conditions. It includes a tank HQ101-5 and a drainage solenoid valve HQ101-4. The tank HQ101-5 is made of welded stainless steel. A hydrogen electrode outlet connector HQ101-8 and a third connector HQ101-6 are installed on the top surface of the tank HQ101-5. A hydrogen electrode inlet connector HQ101-9 is installed on one side of the tank HQ101-5. Gas and water enter through 101-9. A first connector HQ101-2 is installed on the opposite side of tank HQ101-5. A drain solenoid valve HQ101-4 is connected to the first connector HQ101-2 through a second connector HQ101-3. A water level sensor HQ101-1 is installed on the third connector HQ101-6. The water level sensor HQ101-1 extends into tank HQ101-5 and is connected to the programmable controller.
[0019] Among them, the first connector HQ101-2, the third connector HQ101-6, the hydrogen electrode outlet connector HQ101-8, and the hydrogen electrode inlet connector HQ101-9 are all welded to the tank body HQ101-5.
[0020] The hydrogen electrode outlet connector HQ101-8 is connected to a pipe and is connected to the exhaust gas outlet, which is connected to an external gas source.
[0021] The hydrogen electrode inlet connector HQ101-9 is located above one side of the tank body HQ101-5, and the first connector HQ101-2 is located below the other side of the tank body HQ101-5.
[0022] The output end of the drain solenoid valve HQ101-4 is equipped with a drain pipe, which is connected to an external drainage device.
[0023] The second connector HQ101-3 is threaded to the first connector HQ101-2, and the second connector HQ101-3 is threaded to the drain solenoid valve HQ101-4.
[0024] Work process:
[0025] Water is stored in HQ101-5. When the water level is low, the HQ101-1 water level detection sensor does not output a signal to the programmable controller. At this time, the HQ101-4 drain solenoid valve coil is not energized and is in the closed state.
[0026] When the water level is relatively high, the HQ101-1 water level detection sensor outputs a signal to the programmable controller. At this time, the coil of the HQ101-4 drain solenoid valve is energized and is in the open state, starting to drain water.
[0027] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
