Problems solved by technology

[0003] Usually independent functional parts; cut-off valve, filter, flow limiting and pressure reducing valve are designed with too large volume, and the internal dead volume is also too large, the sample gas is not easy to be replaced cleanly, which is not suitable for the monitoring of high-purity gas
[0004] In addition, there are too many connecting joints between the various spare parts, which increases the leakage points

Embodiment Construction

[0024] The present invention will be described in detail below with reference to the drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation mode and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0025] Such as Figure 1-Figure 2 As shown, an analysis and sampling combination valve used in a HYCO production device is installed on the sampling point flange 5 of the process pipeline. The combination valve includes a filter 3, a flow limiting and pressure reduction orifice 2 and 2 sets Needle-shaped shut-off valve with independent flow path, the filter 3, the flow-limiting and pressure-reducing orifice plate 2, and the needle-shaped shut-off valve are all set on the sampling point flange 5. The two needle-shaped shut-off valves are respectively connected with the sampling point flange The ...

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 [0001] The invention relates to a HYCO production device, in particular to an analysis and sampling combination valve used in the HYCO production device. Background technique [0002] Now, in the production of HYCO, the sample flow path of the process analysis system is equipped with a sample flow path cut-off valve (root valve) on the process pipeline to cut off the sample flow path to repair the sample processing system. The sample processing system is filtered and decompressed. , Flow limiting, dehydration and removal of corrosion products and other special components. [0003] Usually each independent functional component; the volume of the shut-off valve, filter, flow limiting and pressure reducing valve is too large, the internal dead volume is also too large, the sample gas is not easy to be replaced cleanly, not suitable for the monitoring of high-purity gas. [0004] In addition, there are too many connection joints between the spare parts, which increases t...
