Abstract
本实用新型涉及一种带水封防干罩碘量瓶，属于水污染监测领域。本实用新型碘量瓶瓶口外表面设有外螺纹，内侧为磨砂斜面，碘量瓶瓶口与防干罩下开口通过螺纹连接，防干罩顶部设有入水口，入水口上设有封盖。本实用新型罩子上下口都拧紧后，水封水体处于一个密闭的空间，能有效减缓碘量瓶水封的蒸发速度，避免了因水封干燥，瓶内进入空气而导致的实验失败。同时有效解决了水样运输过程中水体倾倒，破坏设备的问题。本实用新型克服了现有技术中的缺陷，进行水样测定时，只需将罩子全部拧下，放掉水封，即可进行下一步水体指标测定。本实用新型结构简单、制作费用低，使用方便，在水污染监测上能发挥重要作用。
The utility model relates to an iodine measuring bottle with a water-sealed anti-drying cover, which belongs to the field of water pollution monitoring. The outer surface of the mouth of the iodine bottle of the utility model is provided with external threads, and the inner side is a frosted inclined surface. The mouth of the iodine bottle and the lower opening of the anti-drying cover are connected by threads. The top of the anti-drying cover is provided with a water inlet, and the water inlet is provided with a cover . After the upper and lower openings of the cover of the utility model are tightened, the water seal water body is in a closed space, which can effectively slow down the evaporation speed of the water seal of the iodine measuring bottle, and avoid the experiment failure caused by the dry water seal and air entering the bottle. At the same time, it effectively solves the problem of water dumping and equipment damage during water sample transportation. The utility model overcomes the defects in the prior art. When measuring water samples, all the covers need only be unscrewed, and the water seal is released, so that the next step of water body index measurement can be carried out. The utility model has the advantages of simple structure, low manufacturing cost and convenient use, and can play 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.
