Abstract
The utility model relates to a combined sealing sampler, in particular to a combined sealing sampler used for sampling liquid medium inside a conveying pipe in the production process of chlorosilane. The combined sealing sampler has the characteristics that a material inlet connector 1 is sequentially connected with an adjusting valve 4, a cooler 6, a pressure gage 8, a sampling valve 9, an adjusting valve 10 and a maintaining adjusting valve 12 by a pipeline and then is connected to a waste liquid discharging connector 3; a nitrogen purging connector 2 is connected to the pipeline between the material inlet connector 1 and the adjusting valve 4 after being connected with a nitrogen adjusting valve 5; a sampling connector 18 at the lower part of the sampling valve 9 is connected to a sampling bottle 11 by a pipe; and a gas and liquid discharging pipe 7 is internally connected to the pipe between the adjusting valve 10 and the maintaining adjusting valve 12 by the bottle neck at the upper part of the sampling bottle 11.
Description
Technical field
The utility model relates to the airtight sampler of a kind of combined type, particularly relate to a kind of in the chlorosilane production run to conveyance conduit in the liquid medium airtight sampling thief of combined type of sampling.
Background technology
Chemical industry, electric power, polysilicon industry need regularly or fixed point is carried out check and analysis to the sample in the conveyance conduit, so that make it within specified indication range.At present, domestic chemical industry, polysilicon industry adopt American UOP company sampling product more, and system is neither airtight in its course of work, and sampled result is not representative yet.Though Chinese patent CN96232446 and CN98227015 have adopted the mode of airtight pipeline to sample, its still exist part too much, carry the especially shortcoming of chlorosilane dielectric corrosion of inconvenience, part corrosion-vulnerable medium; While is because its sampling system is comparatively complicated, so its sample time is relatively long, leakage point is many, cost is high, parts replacement is frequent.
Summary of the invention
The purpose of this utility model is the defective that will overcome prior art, a kind of closed pipe sampler is provided, that particularly be suitable for carrying fluid media (medium) such as chlorosilane and pollution-free, do not have leak, cost is low, be convenient to the airtight sampler of pipeline safeguarding, be convenient to operate.
The technical solution of the utility model is: this apparatus features is, material inlet interface 1 is connected to discharging of waste liquid interface 3 after connecting variable valve 1, refrigeratory 6, tensimeter 8, sample valve 9, variable valve 2 10, maintenance variable valve 12 by the road successively, and nitrogen purging interface 2 connects on the pipeline that is connected to after the nitrogen adjustment valve 5 between material inlet interface 1 and the variable valve 1 by the road; The sample connection 18 of sample valve 9 bottoms is connected in the sampling jar 11 through a pipeline; There are a waste discharge gas, liquid pipe 7 in sampling jar 11 top bottlenecks, to be connected to variable valve 2 10 and the pipeline of maintenance between the variable valve 12.
Another characteristics of the present utility model are that described sample valve 9 is by valve body 13, the interface 19 of valve body 13 lower left side, the interface 17 on right side are positioned at valve body 13 middle part spools 16, the valve rod 15 on the spool 16, the valve handle 14 on valve rod 15 tops, and the sample connection 18 of valve body 13 lower ends is formed.
The utlity model has following advantage and effect: 1, realized airtight sampling.2, because this device can carry out carrying out nitrogen purging before nitrogen filled protection and the sampling to sampling jar and return line, so pollution-free, it is more representative to take a sample, and can guarantee sampling quality.3, this device also have do not have to leak, cost is low, be convenient to safeguard, be convenient to operation, characteristics such as (also can be applicable to other industry, as industries such as chemical industry, pharmacy the danger medium that is not easy to the air contact is taken a sample) applied widely.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the sample valve structural representation.
Embodiment
As shown in Figure 1, sampling jar 11 is installed, open variable valve 2 10, opening nitrogen adjustment valve 5 adjusting nitrogen pressures purges sampling line, open 9 pairs of sampling jars of sample valve 11 and carry out nitrogen purging, close sample valve 9, close nitrogen adjustment valve 5, open variable valve 1 and regulate pressure, medium is through subcooler 6, sample valve 9, after discharging of waste liquid interface 3 leads to waste tank, treat that opening sample valve 9 behind the sample displacement pipeline takes a sample, and observes sampling jar 11 liquid levels, close sample valve 9, variable valve 1, open nitrogen adjustment valve 5 adjusting nitrogen pressures the pipeline medium is purged, close nitrogen adjustment valve 5, take off sampling jar 11.Load onto the sampling empty bottle, open nitrogen adjustment valve 5, open sample valve 9,, close nitrogen adjustment valve 5, close variable valve 2 10, finish airtight sampling process sampling jar and return line nitrogen filled protection.
Sample valve 9 is the threeway needle valve, valve rod 15 control below through hole (see figure 2)s; Sampling jar 11 is positioned at sample valve 9 belows, and sample valve 9 connects sampling jar 11 through sample connection 18, pipeline, has bottle holder and bottle stand to support sampling jar 11 outside the sampling jar 11.
