Service life.
Further, first sealing-plug is provided with sealing ring at crushing block.
By using above-mentioned technical proposal, the leakproofness between crushing block and the first sealing-plug can be further increased, is subtracted
Few air enters tube body, pollutes to liquid is tested in tube body.
Further, the extra heavy pipe lower end, which is provided with, takes liquid component.
By using above-mentioned technical proposal, inhaled by taking liquid component that staff can be facilitated directly to take out from extra heavy pipe lower part
Liquid is received, it is time saving and energy saving.
Further, described to take liquid component include the liquid taking port extended downwardly at extra heavy pipe, and is provided at the liquid taking port
Two sealing-plugs, the extra heavy pipe are provided with the rubber hoop for being wound around liquid taking port and the second sealing-plug, and the rubber hoop is recessed
Fall into the seal groove for having chimeric second sealing-plug.
By using above-mentioned technical proposal, staff can remove the second sealing-plug, incite somebody to action by taking down rubber hoop
Absorbing liquid in extra heavy pipe is taken out, without taking out from nozzle；Seal groove is fitted into the second sealing-plug, increases rubber hoop second
Stability on sealing-plug reduces the case where rubber hoop is detached from from the second sealing-plug.
Further, connecting rod is connected between the U-tube body.
By using above-mentioned technical proposal, the structural integrity of U-tube body can be increased by connecting rod, reduce U-tube
Body both ends are close or the deformation far from caused by causes to damage to U-tube body.
Further, it is provided at the nozzle and extends out area under control, the area under control that extends out abuts the first sealing-plug.
By using above-mentioned technical proposal, area under control is extended out by abutting, the close of the first sealing-plug can be further increased
Feng Xing reduces sky and goes to enter U-tube body.
Further, expansion ball one end is provided with cellular glass filter disc in the extra heavy pipe.
By using above-mentioned technical proposal, gas can be made to be separated into minimum bubble to expand tested gas and absorbing liquid
Contact area, thus the higher assimilation effect of the liquid that is absorbed.
Further, the hole count of the cellular glass filter disc be 12, the cellular glass filter disc with a thickness of 5mm.
By using above-mentioned technical proposal, too many hole count will cause aperture and become smaller, and under test gas is difficult to by porous
Glass filter disc, very little hole count will cause aperture and become larger, and the under test gas of process is not easy to react with absorbing liquid, pass through 5mm thickness energy
Enough there is own wt, be maintained at extra heavy pipe bottom, reduces the case where cellular glass filter disc is jacked up by under test gas.
In conclusion the utility model has the following beneficial effects:
