Abstract
The utility model relates to an iodine flask with a water-seal dry-resistant cover, which belongs to the field of water pollution monitoring. According to the iodine flask with the water-seal dry-resistant cover disclosed by the utility model, an external thread is arranged on the outer surface of the neck of the iodine flask, the inner side of the neck is a frosted inclined surface, the neck of the iodine flask is connected with the lower opening of the dry-resistant cover by the thread, a water inlet is formed in the top of the dry-resistant cover, and a sealing cover is arranged on the water inlet. After both the upper opening and the lower opening of the cover of the iodine flask with the water-seal dry-resistant cover disclosed by the utility model are screwed down, a water-seal water body is in an airtight space, and the evaporation speed of the water seal of the iodine flask can be effectively slowed down, thus avoiding the failure of an experiment, caused by the entrance of air in the flask when the water seal dries out; meanwhile, the problem that equipment is damaged due to the pouring out of the water body during a water sample transport process is effectively solved. According to the iodine flask with the water-seal dry-resistant cover disclosed by the utility model, defects in the prior art are overcome, during water sample determination, the next step of water body index determination can be carried out after the cover is completely unscrewed and the water seal is drained. The iodine flask with the water-seal dry-resistant cover disclosed by the utility model is simple in structure, low in production expense and convenient to use and plays an important role in water pollution monitoring.
Description
technical field:
The utility model relates to the anti-dry cover iodine flask of a kind of band water seal, belongs to water pollution monitoring field.
background technology:
Iodine flask is the important vessel that in water pollution monitoring, dissolved oxygen and five-day BOD are measured, the iodine flask Shortcomings using at present, bottleneck water seal is due to limited space, the water seal water yield very little, easily dry, cause air to enter bottle, finally cause water in bottle body dissolved oxygen content to increase, five-day BOD measured value diminishes.The reason that causes these problems is mainly that five-day BOD minute interval is longer, experimenter often easily forget timing add water seal, cause water seal to evaporate completely, air enters.What is more important after water sampling scene is fixing, easily causes bottleneck disorderly to spill for the water body of water seal in water sample transport, and air is seized the opportunity and entered in bottle, and the water body spilling also can affect water sample transporting equipment and other samples.
utility model content:
The utility model is that a kind of sealing is strong, the anti-dry cover iodine flask of band water seal of having avoided water seal place current to lose.
Technical solution:
The utility model iodine flask bottleneck outer surface is provided with external screw thread, and inner side is frosted inclined-plane, and iodine flask bottleneck can closely be connected by screw thread with anti-dry cover under shed, and anti-dry cover top is provided with water inlet, and water inlet is provided with capping.
Described iodine flask mouth is provided with the stopper with matte surface, and stopper coordinates with bottle sealing.
After the utility model cover upper and lower opening is all tightened, water seal water body, in an airtight space, can effectively slow down the evaporation rate of iodine flask water seal, has avoided dry because of water seal, enters air and the failure of an experiment of causing in bottle.Efficiently solve water body in water sample transportation simultaneously and topple over, destroy the problem of equipment.
While carrying out water determination, only cover all need be backed out, be bled off water seal, unstop and can carry out water body index determining.The utility model is simple in structure, manufacturing cost is low, easy to use, on the sample collection of water environment pollution and index determining, can play a significant role.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the disassembly diagram of Fig. 1.
detailed description of the invention:
Embodiment 1: a kind of iodine flask with the anti-dry cover of water seal, comprises iodine flask body 8, stopper 6 and cover 3; Bottle and stopper are made materials'use glass, and cover and lid all use hard transparent plastic.
Further iodine flask bottleneck 7 outsides are threaded, and inner side is frosted inclined-plane, and bore is up big and down small, facilitates stopper 6 jam-packs.
Further iodine flask is with the stopper 6 of matte surface, and stopper diameter is up big and down small, and protrude for pointed lower end, can enclosing cover at bottleneck, frosting can ensure be combined closely with iodine flask mouth, the pointed sub bottle interior air residual that causes for 6 o'clock of capping plug that prevents in lower end.
Further: iodine flask mouth is threaded with the under shed 5 of cover 3, this cover can closely be screwed on iodine flask bottleneck by screw thread, forms a new space, adds water and enters as water seal.
Further: upper shed 2 outsides of cover 3 are threaded, and upper shed is furnished with small lid 1, there is screw thread small lid inner side, and small lid bore and cover 3 upper sheds can be combined closely, and can prevent that water seal water evacuator body is too fast after building.
The graduation mark 9 that iodine flask body 8 volumes are 250ml, cover 3 volume 10ml left and right, added water seal after 10 days, and the water seal water yield is greater than 9ml, has no Bubble formation in iodine flask.Do control experiment with conventional iodine measuring bottle simultaneously, find conventional method after 3 days water seal dry totally, in iodine flask, have Bubble formation, after 5 days, bubble enters manyly, occurs the water body vacancy of 3mm left and right below iodine flask mouth stopper.Visible, the utility model is respond well.
