Description
Technical field
The utility model relates to a kind of sampling container of water quality research, specifically a kind of sampling bottle dedicated gathered containing volatile matter, oxygen sensitivity material water sample.
Background technology
The sampling bottle used in water quality research process is generally vial, and its shape is all generally narrow-mouthed bottle, and namely body portion is that particle size is cylindric, and bottleneck portion is that thin footpath is cylindric, and the transition portion between body and bottleneck is the ring arc surfaced in evagination.
Sampling bottle mostly is glass material and makes, its weak point existed, and one is easily broken in carrying and transportation; Two is sample bottles of water sample for splendid attire, and after bottle sealing, in micro-artesian condition in bottle, this just makes between sample bottle and sample bottle or between sample bottle and other object, and slightly the phenomenon of bottle breakage just very easily occurs in collision.And; in transportation; generally also packaging protecting is carried out with flexible materials such as bubble cushions in the outside of the sample bottle of splendid attire water sample; and flexible packages used easily adsorbs or sticky glutinous pollutant; and bring in sample insulation can thereupon; thus pollute the storage environment of sample bottle, indirect pollution may be produced to sample in bottle, add the probability of contaminated samples.
According to the requirement of the Sampling techniques specification gathered containing volatile matter, oxygen sensitivity material water sample, when water sample enters bottle, water sample liquid level steadily rises bottle planted agent, forbid the situation occurring that water body acutely changes, namely the speed requiring liquid level to rise should evenly or slowly change reposefully, water injection rate can not be neglected suddenly slow, suddenly big or suddenly small soon, the relative equilibrium of such guarantee water sample and the wherein molecular motion of contents matter, reduce disturbing phenomenon, avoid overflowing from water sample and lost and cause the problem that sample fidelity reduces because of volatile matter contained by sample.
And use existing sampling bottle collection containing volatile matter, oxygen sensitivity material water sample time, the bottle section of sampling bottle and the process of pass is injected at water sample, liquid level ascending velocity is more uniform, but when liquid level rises in the process of the transition section between bottle section and pass, due to the nonlinearities change of volume, the speed causing liquid level to rise is non-linear increase, and, the acceleration that liquid level rises neither a definite value, more up, the acceleration that liquid level rises is larger, stronger to the perturbation action of water sample.Until liquid level is by the intersection of transition section and pass, the acceleration that liquid level rises reaches maximal value, the level of disruption of water sample also reaches maximum, and liquid level is after rising enters into pass, liquid level rise acceleration can from cross intersection maximal value moment again involution be zero, such acceleration change, reaches maximum to the level of disruption of sample, and herein from bottleneck very close to, add the spilling of volatile matter in water sample and lost probability, reduce the fidelity of sample.
The gland bonnet that existing sampling bottle uses mainly contains square thread lid (similar mineral water bottle cap) and the large class of flat insert cover (as frosted mouth glass stopper) two.The surface of contact of these two kinds of bottle caps and water in bottle sample is all planar structure.After water sample fills sampling bottle, due to the capillary effect of water, be the arcwall face a little more than bottleneck and in microprotrusion shape at the liquid level of bottle mouth position.Be tamping in the process of sampling bottle bottleneck with square thread bottle cap, in the moment that the cambered surface water body of bottle mouth position contacts with bottle cap inner plane, the convex globoidal water body of bottle mouth position can be subject to the extruding of bottle cap inner plane and have a small amount of liquid to flow out outside sampling bottle, if firmly the speed that screws that is slightly large or bottle cap is slightly fast, then while convex globoidal water body has part to be extruded bottleneck, water sample in bottleneck also may be taken out of a small amount of or micro-liquid under inertia effect, a little space will be reserved like this at the bottle mouth position of sampling bottle, and filled by air, thus, in sample bottle after the complete fastening of bottle cap, the space of being filled by air will be produced, make in sample bottle, to have left air, thus can not meet containing volatile matter, the requirement of oxygen sensitivity material water sampling technical manual, become waste sample.
In addition, in the actual mechanical process of sampling location, be difficult to sampling bottle is vertically placed.After water sample fills sampling bottle, slightly large once sampling bottle degree of tilt, the liquid level water body of bottle mouth position convex globoidal will flow out bottleneck, makes to have left air in the sample bottle after capping.And when sampling bottle degree of tilt is less, gravity suffered by each particle in surface of the liquid level water body of bottle mouth position convex globoidal along the component of cambered surface tangential direction when being not more than the surface tension of cambered surface water body, although can static balancing be kept, but the center of gravity of the water body in convex globoidal can offset to the vergence direction of sampling bottle, in the moment contacted with bottle cap end face, more easily flow out outside bottle because being squeezed, leave air in sample bottle after making capping, the demand of technical standard of the water sampling containing volatile matter, oxygen sensitivity material can not be met.
Although flat embedded sampling bottle cap can meet the associated specifications filling up sample bottle, be unfavorable for carrying and transport.Particularly glass bottle with frosted glass opening lid is not suitable for gathering and contains volatile matter and the water sample containing oxygen sensitivity material in alkaline.
Known by above-mentioned analysis, when sampling bottle fill water sample carry out bottle cap tighten operation time, careless slightly, bubble will be left in sample bottle, cause sampling unsuccessfully, only again must change bottle sampling, waste the sampling time, reduce work efficiency.And, pouring out the sampling bottle after water sample because leaving bubble, can't directly reuse, laboratory must be taken back after the operations such as cleaning, drying, packaging, could continue to use in the sampling process of next time.
According to the demand of technical standard containing volatile matter, the water sampling of oxygen sensitivity material, use existing sampling bottle to sample, have two kinds of methods of operating.
The first method of operating is that the effluent pipe mouth of sampling thief is stretched in sampling bottle, and keep certain distance at the bottom of effluent pipe mouth distance bottle, when injecting water sample, along with the rising of liquid level in bottle, rising pipe also together slowly promotes.In the process, the distance in bottle between liquid level and effluent pipe mouth should remain unchanged, and the rising pipe inserted in bottle is answered vertical-lifting and must not be shaken, to avoid the spilling of contained volatile matter in water sample and to scatter and disappear.But in actual mechanical process, because the aquifer yield of sampling thief is very little, fill the time that one bottle of water sample approximately needs at least 5 minutes, all can there is jitter phenomenon in the hand that operating personnel grip rising pipe, and rising pipe on put forward the state that operation is also difficult to accomplish the distance of the mouth of pipe and rising liquid level is remained unchanged, this just makes water sample be disturbed, the spilling of the volatile matter appearance part contained in sample and scattering and disappearing, and the fidelity of institute's collected specimens is declined.And, the process of sampling bottle is injected at water sample, effluent pipe mouth due to sampling thief is in the top of liquid level all the time, the tiny current flowed out from the mouth of pipe contact with air all the time, under this sampling environment, the oxygen sensitive materials contained in water sample are just oxidized in the process entering sampling bottle, and sample distortion situation also just cannot be avoided naturally.
The second method of operating is that the effluent pipe mouth of sampling thief is extend in sampling bottle, maintain a certain distance constant at the bottom of effluent pipe mouth distance bottle, when water sample be injected in bottle, liquid level continue to rise to close to bottle mouth position time, again effluent pipe mouth is slowly steadily promoted, when effluent pipe mouth arrives bottle mouth position, water sample just in time fills sampling bottle.In this operating process, liquid level steadily rises, and the disturbance of effluent pipe mouth to water sample is less, and in sample, contained volatile matter not easily overflows, and the fidelity of the sample gathered is higher.
A common ground of above two kinds of methods of operating all the effluent pipe mouth of sampling thief is extend in sampling bottle; After sample is full of sampling bottle, is all seal a bottle with aforementioned bottle cap, easily in bottle, leaves air, make sample distortion.
