Abstract
The utility model discloses a gas pipeline drainer device, which is mainly designed specific to the problems of complicated structure, incapability of realizing online continuous drainage and the like in the conventional medium and low-pressure gas pipeline drainers. The gas pipeline drainer device disclosed by the utility model comprises a shell and a float switch which is arranged inside the shell, is switched on under the action of buoyancy and is switched off under the action of gravity, wherein the shell is provided with a water inlet pipe; the bottom of the shell is provided with a drain outlet and a drain pipe. The gas pipeline drainer device is simple in structure, can be generally applied to medium and low-pressure gas pipe networks, and can be used for realizing online drainage.
Description
Technical field
The utility model relates to a kind of gas pipeline drainer device.
Background technique
At present, the domestic gas pipeline drainer that generally adopts sealing structure for water for low-pressure gas pipe drainage, for the draining of middle pressure gas pipe line, existing common way is to adopt the dry condensate water hydathode that is interrupted drainage pattern.There is following shortcoming in above two kinds of hydathodes: low-pressure gas hydathode need supplement new water, and small flow overflows, waste water resource, and the design of water tight compartment, complex structure, the dirt in each water tight compartment need to be cleared up respectively; Middle pressure coal gas drainer can not be realized on-line continuous draining, and manual operation can not guarantee in time the condensed water in coal gas to be discharged, and also can cause gas leakage casualty accident in addition.
Model utility content
For the problems referred to above, the utility model provide a kind of in, low-pressure gas device for cleaning pipeline with, without supplementing water, the gas pipeline drainer device of draining online.
For achieving the above object, this practical gas pipeline drainer device, comprises shell and is arranged on described enclosure buoyancy and open the float switch that gravity is closed, described shell is provided with intake pipe, and described outer casing bottom is provided with sewage draining exit and waste pipe.
Further, the upright guide rail that described float switch comprises with in described enclosure, end face is connected in the heart, and be set in the floating drum on described guide rail, described floating drum bottom is provided with base, the upper drain opening center-aligned of the bottom surface of described base and described waste pipe, described base end face is provided with seal arrangement.
Further, described guide rail is cylindrical slideway, and described floating drum is provided with the cylindrical hole suitable with described cylindrical slideway.
Further, described intake pipe is provided with cutting-off valve.
Further, in described enclosure, end face is provided with spacing overhead gage.
Especially, the upper drain opening of described waste pipe exceeds described outer casing bottom.
Particularly, the cross section of described shell is circular, square or polygonal, and described enclosure is sealing configuration.
Particularly, the cross section of described floating drum is circular, square or polygonal.
Particularly, described drain trap device is supported or is hung over side of buildings by the fixed block being connected on described shell by the floor stand being connected on described shell.
The utility model gas pipeline drainer device, adopt buoyancy to open the float switch that gravity is closed, ascending motion by described floating drum under floating function and the descending motion under Action of Gravity Field realize draining and the water of hydathode, compared with prior art, simple in structure, make easily, convenient maintenance, and in having, low-pressure gas pipe network is general, can realize the advantage of unattended online draining, reduced cost of labor and gas poisoning dangerous simultaneously.
Accompanying drawing explanation
Fig. 1 is the hull-borne structural representation of the utility model gas pipeline drainer device;
Fig. 2 is the water status architecture schematic diagram of the utility model gas pipeline drainer device.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, gas pipeline drainer device in the present embodiment, comprise shell 6 and be arranged on described shell 6 internal buoyances and open the float switch that gravity is closed, described shell 6 is provided with intake pipe 1, described shell 6 bottoms are provided with sewage draining exit 3 and waste pipe 7, the upper drain opening of described waste pipe exceeds described outer casing bottom, prevent that dirt from stopping up described waste pipe, the inner upper end face of described shell 6 is provided with spacing overhead gage 8, be used for limiting the lifting height of described floating drum 4, play position-limiting action, impulse force when floating drum 4 rises described in simultaneous buffering, protective gear is avoided damaging; The upright guide rail 2 that described float switch comprises with in described enclosure, end face is connected in the heart, and be set in the floating drum 4 on described guide rail 2, described floating drum 4 bottoms are provided with base, the upper drain opening center-aligned of the bottom surface of described base and described waste pipe, described base end face is provided with seal arrangement 5.
During normal working, described floating drum 4 is supported on described waste pipe in drain opening owing to pressing in deadweight and coal gas, moisture in coal gas enters hydathode continuously by described waste pipe intake pipe 1, the suffered buoyancy of described floating drum 4 constantly increases, after liquid in hydathode reach a certain height, break through himself gravity and coal gas and atmosphere while acting on the pressure on sealing surface due to inside and outside differential pressure, described floating drum 4 upwards floats along described guide rail 2, and now the water in hydathode is forced out outside hydathode along the waste pipe 7 of opening; As shown in Figure 2, draining causes the water level in hydathode constantly to decline, described floating drum 4 under self gravitation effect also along with decline, the seal arrangement 5 of final described floating drum 4 bottoms again with waste pipe on drain opening coincide, drainage procedure stops.After this will repeat aforesaid polywater action.
In above-described embodiment, described guide rail is cylindrical slideway, and described floating drum is provided with the cylindrical hole suitable with described cylindrical slideway, facilitates described floating drum to move up and down at described guide rail.
In above-described embodiment, described intake pipe is provided with cutting-off valve, the condensed water importing hydathode of discharging for controlling gas pipe line.
In above-described embodiment, the cross section of described shell is circular, square or polygonal, and described enclosure is sealing configuration.
In above-described embodiment, the cross section of described floating drum is circular, square or polygonal.
In above-described embodiment, described drain trap device is supported or is hung over side of buildings by the fixed block being connected on described shell by the floor stand being connected on described shell.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
