Description
Technical field
The utility model relates to a kind of sample cock, specifically, relate to no leakage analyzing liquid material sample cock under a kind of air-tight state.
Background technology
At present, in domestic petroleum, chemical industry, the medicine production,, all can set up the analysis and Control of production run, utilize the quality analysis of process product, determine the adjustment of technological parameter in order to guarantee the quality of the product that it is produced.Its mode mainly is exactly that employing taking-up chemical material in process pipe carries out various analyses, draws analysis result.
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 sample 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 jar and receive the material that flows out, obtained material could be represented the material of this moment producing, and resultant like this analysis result could be represented the real quality of production product this moment!
There are two shortcomings in such sampling means: 1, because operating personnel's gimmick is inconsistent, the material of getting is not necessarily just represented instantaneous sample; 2, the discharge material before the sampling could be collected, and directly enters the trench foul water system, not only increases 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 leak cruelly in air at last, also can generate HCL gas with the water reaction.Thereby the problem of analytical sampling just seems particularly outstanding, nearly more than 100 of product material sampling spots 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 on-site sampling are exactly on-the-spot to need 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 0.25Kg 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 20,000 yuan per ton more than, total value is estimated as 500,000 yuan; Angle from environmental protection: also pollute and corrode (all being strong acid, alkali a lot), increased the weight of the load of wastewater treatment as the concentrated sulphuric acid to device! Consider from angle itself that analyze: contact because monomer very easily divides with water in air, produce reaction, leak cruelly during sampling in air, bring influence can for the 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 sample valve, effect is fine, but structure is very complicated; and environment for use had higher requirement, cost is very high, has increased the production cost of enterprise.
