Abstract
The invention relates to an analyzing and sampling combined valve for an HYCO production device. The analyzing and sampling combined valve is installed on a sampling point flange on a technological pipe, and comprises a filter, a current-limiting depressurization pore plate and two needle-shaped stop valves with independent flow paths, wherein the filter, the current-limiting depressurization pore plate and the needle-shaped stop valves are installed on the sampling point flange; the sampling point flange, the needle-shaped stop valves, the filter and the current-limiting depressurization pore plate are sequentially connected. Sample gas flows through the sampling point flange, and enters into the filter after entering into the needle-shaped stop valves with independent flow paths through being divided into two paths, the sample gas filtered by the filter is subjected to depressurization through the current-limiting depressurization pore plate, and at last the sample gas is conveyed. Compared with the prior art, the analyzing and sampling combined valve has the advantages of simple structure and high analysis and measurement accuracy and the like, and is convenient to disassemble and good in airtight performance.
Description
Technical field
The present invention relates to a kind of HYCO process units, especially relate to a kind of analytical sampling for HYCO process units combination valve member.
Background technology
Now, in HYCO produces, the sample flow path of process analysis system is on process pipe, arrange sample flow path stop valve (root valve), to cut off sample flow path to keep in repair sample processing system, sample processing system by filtering, reduce pressure, current limliting, dewatering and removing the special-purpose members such as erosion forms.
Usual each AFU; The volume of stop valve, filtrator, current limliting relief valves designs is too large, and internal dead volumes is large too, and sample gas is not easily totally replaced, the monitoring of not too suitable high-purity gas.
In addition, the jointing between each spare part is too many, adds leakage point.
Summary of the invention
Object of the present invention be exactly provide to overcome defect that above-mentioned prior art exists that a kind of structure is simple, analysis to measure accuracy is high, easy accessibility and the good combination of the analytical sampling for the HYCO process units valve member of airtight performance.
Object of the present invention can be achieved through the following technical solutions:
A kind of combination of the analytical sampling for HYCO process units valve member, be arranged on the sampling spot flange of process pipe, described combination valve member comprises the needle stop valve of filtrator, current limliting step-down orifice plate and the independent stream of 2 cover, described filtrator, current limliting step-down orifice plate, needle stop valve are all located on sampling spot flange, and described sampling spot flange, needle stop valve, filtrator, current limliting step-down orifice plate connect successively;
Sample gas is flow to by sampling spot flange, enters filtrator after a point two-way enters the needle stop valve of independent stream, by the sample gas after metre filter by the step-down of current limliting step-down orifice plate, finally carries sample gas.
2 described cover needle stop valves are connected with the center pit of sampling spot flange respectively.
Described filtrator is the dust filter unit of 100 μ levels.
The diameter of described current limliting step-down orifice plate is 0.1mm.
The input end of described current limliting step-down orifice plate is connected with filtrator, and output terminal is connected with gas export line.
Described gas export line is SS316 stainless steel pipeline.
The output port of described gas export line is connected with the double card bell and spigot joint for sealing.
The making material of described current limliting step-down orifice plate is graphite tetrafluoroethene.
Compared with prior art, the present invention has the following advantages:
One, 2 cover switch needle stop valves, filtrator, punctured board ferrule fitting are integrated on one piece of flange plate, obtain the function of multiple each individual components, simplify several samples processing element and arrange.
Two, total dead volume of each parts greatly reduces, and sample gas is easy to be totally replaced, improves analysis to measure accuracy, the sampling of suitable high-purity gas.
Three, dual flow path is parallel is arranged, and is convenient to not maintenance shut-downs.
Four, ferrule is adopted to connect, easy accessibility and airtight performance is good.
Five, the material contacting sample gas is graphite tetrafluoroethene and SS316 stainless steel, can not produce pollution to measured gas, ensures instrumental analysis correctness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the cut-open view of A-A in Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As Figure 1-Figure 2, a kind of combination of the analytical sampling for HYCO process units valve member, be arranged on the sampling spot flange 5 of process pipe, the needle stop valve that described combination valve member comprises filtrator 3, current limliting step-down orifice plate 2 and 2 overlaps independent stream, described filtrator 3, current limliting step-down orifice plate 2, needle stop valve are all located on sampling spot flange 5,2 cover needle stop valves are connected with the center pit of sampling spot flange 5 respectively, and needle stop valve, filtrator 3, current limliting step-down orifice plate 2 connect successively.Described filtrator 3 is the dust filter unit of 100 μ levels.The diameter of described current limliting step-down orifice plate 2 is 0.1mm, and making material is graphite tetrafluoroethene.。The input end of described current limliting step-down orifice plate 2 is connected with filtrator, and output terminal is connected with gas export line, and this gas export line is SS316 stainless steel pipeline.The output port of gas export line is connected with the double card bell and spigot joint 1 for sealing.
Sample gas is flow to by the center pit of sampling spot flange 5, and point two-way enters the needle stop valve of independent stream, and the switch of needle stop valve, can open or cut out sample gas stream, closes sample gas stream, can overhaul each parts of sample gas pre-service.Sample gas enters the dust filter unit of 100 μ levels, prevents rear class pipeline, parts blocked.The current limliting step-down orifice plate of diameter 0.1mm is installed after filtrator, when the gas flow of pressure 6---7Bar is through this orifice plate, pressure can be limited to 0.5---0.7Bar, such pressure can at internal diameter 4mm, SS316 stainless steel pipeline take flow as the speed conveying sample gas of 150L/h---200L/h, can meet the needs of the discharge of rear class fast loop and instrument operation.Gas vent connects employing double card cover and is firmly tightly connected, and can conveniently accomplish that No leakage connects.
