Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Referring to the attached drawings 1-3, the positive pressure automatic water drainage device comprises a water inlet pipe 1, a pressure balance pipe 2, a floating ball 3, a shell 4, a guide rod 5, a sealing ball 6 and a one-way check valve 7, wherein the water inlet pipe 1 is connected to the lower portion of the side wall of the shell 4, the floating ball 3 is sleeved on the guide rod 5, an L-shaped fixing piece 101 is arranged at the top end of the inside of the water drainage device, a ventilation valve 102 is mounted on the L-shaped fixing piece 101, the guide rod 5 is connected to the lower end of the ventilation valve 102, one end of the pressure balance pipe 2 is connected to the air inlet end of the ventilation valve 102, the other end of the pressure balance pipe 2 is connected to an external gas extraction pipe 8, and the air outlet end of the ventilation valve 102 is connected.

Wherein, casing 4 bottom is equipped with drainage channel, ball sealer 6 and one-way check valve 7 are installed casing 4 and drainage channel's kneck.

The top end of the shell 4 is fixedly connected with a transparent plate, and the shell 4 is sealed through the transparent plate. The personnel of being convenient for observe the inside operating condition of ware that drains, when breaking down, can in time maintain.

Wherein, both ends of the L-shaped fixing member 101 are respectively fixedly connected with the inner side wall of the housing 4.

In the present invention, the water inlet of the water inlet pipe 1 must be lower than the bottom of the compressed air pipe 10. The accumulated water in the compressed air pipe 10 can be normally discharged into the water drainage device.

The joint of the pressure air pipe 10 and the water inlet pipe 1 is provided with a gate valve 11, and the gate valve 11 is connected with the water discharger through a hose. So as to be disconnected with the compressed air pipeline when the water discharger is maintained.

In an embodiment of the present invention, a precipitator is further installed between the water discharger and the compressed air pipe 10, and the precipitator is used for precipitating the filth inside the compressed air pipe 10. The sundries in the pipeline of the air compression pipe 10 are prevented from accumulating in the water drainage device, so that the drainage pipeline is prevented from being blocked, and the normal work of the water drainage device is prevented from being influenced.

The working principle of the positive pressure automatic water drainage device is as follows:

when the positive pressure automatic water drainage device works, the water inlet pipe 1 is communicated with the compressed air pipeline through the hose, and the one-way check valve 7 is in a closed state when the pressure between the inside of the automatic water drainage device and the gas extraction pipe 8 is balanced. When carrying out the pressure measurement, let in gas through gas drainage pipe 8 in to pressure balance pipe 2, ponding appears in the pressure-blast pipeline, behind the long-pending sediment, pressure unbalance in pressure balance pipe 2, ponding can flow into automatic ware that drains through inlet tube 1, ponding along with in the automatic ware that drains constantly increases, after ponding in the ware that drains reaches a certain position, promote floater 3 come-up under the effect of ponding buoyancy, floater 3 receives buoyancy to drive guide arm 5 upward movement, and then drive ball sealer 6 and shift up, one-way check valve 7 is opened, ponding pressurized action in the casing 4, discharge through drainage channel 12. After water is discharged, the liquid level is reduced, the floating ball 3 falls down to drive the guide rod 5 to fall, the one-way check valve 7 is closed, and the water discharging process is finished, so that the circular automatic water discharging is realized.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
