Description
Technical field
The utility model relates to a kind of sampler that assay is used that is used for, and relates in particular to a kind of sealed mode quantitative sampling valve that under airtight state, does not have leakage quantitative sampling analysis usefulness, and relates to the making method of this sealed mode quantitative sampling valve.
Background technique
At present, in domestic petroleum, chemical industry, medicine, the printing and dyeing production process,, all can set up the analysis and Control of production process, utilize the quality analysis of process product, confirm the adjustment of process parameter for the quality of its product of producing.Its mode mainly is exactly to be employed in the interior chemical material that takes out of process pipe to carry out various analyses, draws analysis result.General sampling process such as figure below:
On the pipeline of Flow of Goods and Materials.Weld an arm, a valve is installed.During sampling, for guaranteeing instantaneity, the accuracy of the material of getting, opening valve earlier, arm cecum partial material is drained a part, generally speaking, all is to enter trench.When the material of discharging is abundant, at this time just to use sampling bottle and receive the material that flows out, the material of being obtained could be represented the material of this moment producing, and resultant like this analysis result could be represented the real quality of this moment producing product!
There are three shortcomings in such sampling means: 1; Because that the material that relates to of Production in Chemical Plant has is inflammable, the composition of strong acid, alkali or severe toxicity; In opening the process of valve because there being the pipe internal pressure splash takes place easily; Very easily injure the sampling staff, safety in production is constituted very big hidden danger.2, because operator's gimmick is inconsistent, the material of getting is not necessarily just represented instantaneous appearance.3, the discharge material before the sampling could be collected, and directly gets into the trench foul water system, has not only increased the material waste, and has caused pollution to environment!
With domestic organochlorosilane monomer production industry is the example explanation: in one 60,000 tons/year organochlorosilane monomer factory, and also can supporting one 40,000 tons/year ion film caustic soda process units.Because the organochlorosilane material very easily reacts with water, just be exposed in the air at last, also can be reacted into HCL gas with water.Thereby the problem of analytical sampling just seems particularly outstanding and necessary; Nearly more than 100 of product material sample points on the various pipelines of this kind manufacturing enterprise on-site; Wherein relate to soda acid discharging or just reach about 80 with material that water can react, it is per ton that the highest material price can reach 2.5 ten thousand yuan of unit prices! The characteristics of field sampling are exactly that the scene needs discharging on the spot, are up-to-date style so that get suitable, good reference as process control!
Respectively press the normal two hours each approximately 0.15～0.25KG of sampling every day, be about 120KG altogether, 1 year by just calculating in 330 days nearly surplus in the of 40 ton.From considering economically: a lot of production unit costs are all very high; Price all 1.6～20,000 yuan per ton more than; Total value is estimated as 700,000 yuan: from the angle of environmental protection: also pollute to device and corrode (all being strong acid, alkali a lot, like the concentrated sulphuric scid), increased the weight of the load of sewage treatment! Consider from angle itself that analyze: since monomer very easily with airborne contact with moisture, produce reaction, be exposed to during sampling in the air, bring influence can for the degree of accuracy of analyzing, the result is not accurate enough.
In recent years, domestic a lot of chemical enterprises, particularly organosilicon industry were in order to protect environment; Introduced external airtight sampling cock, effect is fine, but structure is very complicated; And Environmental Conditions had higher requirement, cost is very high, has increased the cost of production of enterprise!
