Abstract
An automatic draining device for condensed water or leaking water in an aeration pipeline comprises a water tank, a draining and exhausting stand pipe and a float bowl valve. According to the automatic draining device, the condensed water or the leaking water is sprayed out through pressurized air; under the condition that the condensed water or the leaking water in the aeration pipeline is basically drained, the outlet is basically closed, only allowing little gas to flow out; and meanwhile, when water is accumulated in the pipeline, the water outlet can be automatically opened widely to drain the accumulated water rapidly.
Claims7
An automatic draining device for condensed water or leaking water in an aeration pipeline, the automatic draining device comprising:
- a water tank, a draining and exhausting stand pipe and a float bowl valve, wherein,
- an overflow tank is provided above the water tank, an emptying valve is provided below the water tank, and a limiting baffle is provided at a middle-lower portion of one side of the water tank;
- a top of the draining and exhausting stand pipe is communicated with the water tank, a draining and exhausting pipe outlet is provided in the top of the draining and exhausting stand pipe, the draining and exhausting pipe outlet is provided with a micro notch on one side close to an air collecting hood, wherein
- the micro notch enables the float bowl valve to be always kept in a closed state, gas in an aeration pipe leaks out only from the micro notch, and a bottom of the draining and exhausting stand pipe is communicated with a bottom of an aeration branch pipe;
- a check valve is provided at a position close to a bottom of an inside of the water tank and below the draining and exhausting pipe outlet;
- and
- the float bowl valve is provided inside the water tank, the float bowl valve comprising:
- a float bowl, an air collecting device and a valve plug lever, and the air collecting device is communicated with a lower portion of the float bowl and is used for collecting air in the water tank into the float bowl;
- a valve plug is provided at a bottom of the valve plug lever, and when an amount of gas in the float bowl reaches a maximum, the float bowl floats, and the float bowl drives the valve plug lever to gradually move the valve plug close to a position above the draining and exhausting stand pipe to close the draining and exhausting pipe outlet in the top of the draining and exhausting stand pipe;
- and
- when no gas exists in the float bowl, an edge of one side of the float bowl falls onto the limiting baffle due to gravity, and the float bowl drives the valve plug to get far away from the draining and exhausting pipe outlet through the valve plug lever.
