Detailed Description
The present invention is made with reference to fig. 1.
The suspended low-pressure leakage-proof gas drainer comprises a condensed water collecting tank 2, a gas-water separating pipe 15, an exhaust pipe 6, an overflow pipe 7 and a suspension frame 1, wherein the exhaust pipe 6 is fixedly arranged at the top of the gas-water separating pipe 15, the lower end of the overflow pipe 7 is communicated with the lower part of the gas-water separating pipe 15, the upper end of the condensed water collecting tank 2 is communicated with a gas pipe through a flange 3, so that condensed water in the gas pipe flows into the condensed water collecting tank 2, and the gas-water separating pipe 15 and the condensed water collecting tank 2 are fixedly arranged on the suspension frame 1; the method is characterized in that: a liquid level control tank 11 is fixedly arranged on a bottom plate of the suspension bracket 1, the upper end of the liquid level control tank 11 is communicated with the upper part of a condensed water collecting tank 2 through a second communicating pipe 14, the middle part of the liquid level control tank 11 is communicated with the lower part of the condensed water collecting tank 2 through a first communicating pipe 12, the bottom of the liquid level control tank 11 is communicated with the middle part of a gas-water separating pipe 15 through a third communicating pipe 8, a drain valve 10 is arranged on the third communicating pipe 8, a ball float valve is arranged at the opening part of the third communicating pipe 8 in the cavity of the liquid level control tank 11, condensed water stored in the condensed water collecting tank 2 flows into the liquid level control tank 11 through the first communicating pipe 12, the ball float valve is opened along with the rising of the liquid level in the liquid level control tank 11, when the drain valve 10 is opened, the water in the liquid level control tank 11 enters the gas-water separating pipe 15 through the third communicating pipe, the water is discharged from the overflow pipe 7.
The mounting bracket 4 is fixedly arranged on the top plate of the suspension bracket 1, and the mounting bracket 4 can also be arranged on the bottom plate of the suspension bracket 1, so that the suspension bracket 1 can be suspended and fixed on a wall or a frame rod beside a gas pipe.
