Abstract
The utility model discloses an empty gas analysis of branch that can arrange sweeping gas outward concentrates sample cabinet belongs to annex for the gas analysis, and its structure includes the cabinet body, and the cabinet is internal to be provided with a plurality of sampling channel side by side, and sampling channel one end is the sample gas and exports for sample gas entry, the sampling channel other end, the last sample valve that is equipped with of sampling channel last being equipped with of sampling channel sweeps the pipeline, sweeps pipeline one end and is linked together with sampling channel, sweeps the pipeline other end and is linked together with the blow -down pipe, and blow -down pipe one end is sealed, and the blow -down pipe other end leads to outdoorly, the intercommunication point that sweeps pipeline and sampling channel lies in between sample gas entry and the sample valve, sweeps and is equipped with the blow down valve on the pipeline. When sweeping, close the sample valve, open the blow down valve, sweep waste gas can discharge through the blow -down pipe outdoor, convenient operation and eliminated the potential safety hazard.
Description
Technical field
This utility model relates to a kind of gas analysis adnexa, and sampling cabinet is concentrated in specifically a kind of space division gas analysis that can arrange outward purging gas。
Background technology
Air separation plant is in process of production, require the analysis site gas of each position of air separation column is sampled inspection, analyzed oxygen content gas is more higher or on the low side than normal air, and need with sample gas, sampling pipe to be purged before analyzing, purging gas is directly discharged into indoor and can cause indoor oxygen-containing too high or too low, there is hidden danger。
The chemical examination of current gas sets a valve cabinet in laboratory, analyzes gas and introduces laboratory valve cabinet by sampling pipe is unified, by the sampling of the valve each sample gas of Valve controlling cashier's office in a shop, opens valve and purge during sample analysis。Shown in Fig. 1 of current valve cabinet such as Figure of description, some sampling pipes 2 it are set side by side with in cabinet 1, sampling pipe 2 is provided with sampling valve 3, the valve cabinet of said structure is when purging, sampling valve 3 is opened, and sample gas directly comes indoor through sampling pipe 2, it is impossible to effectively control to purge waste gas, laboratory needs forced ventilating, and operation is inconvenient and there is potential safety hazard。
Utility model content
For the problems referred to above, the purpose of this utility model is in that to provide a kind of space division gas analysis concentration sampling cabinet can arranged outward and purge gas, and the controlled tubing giving sufficient strength of this sampling cabinet purges gas and is discharged into outdoor。
The technical scheme in the invention for solving the technical problem is: can arrange outward the space division gas analysis purging gas and concentrate sampling cabinet, including cabinet, some sampling pipes it are set side by side with in cabinet, sampling pipe one end is sample gas inlet, the sampling pipe other end is sample gas outlet, sampling pipe is provided with sampling valve, described sampling pipe is provided with purging pipeline, purge pipeline one end to be connected with sampling pipe, purge the pipeline other end to be connected with blow-down pipe, blow-down pipe one end is closed, and the blow-down pipe other end leads to outdoor；Purge the connectivity points of pipeline and sampling pipe between sample gas inlet and sampling valve, purge pipeline and be provided with blow down valve。
Further technical scheme is: described purging pipeline is connected by three way cock with sampling pipe。Three way cock can not only ensure the reliable connected of pipeline enclosure, moreover it is possible to improves the intensity of connectivity part。
Structure for making equipment is compacter, and further technical scheme is: the blind end of described blow-down pipe is positioned at inside cabinet。
Further technical scheme is: described sampling valve is fixedly mounted on cabinet。
Further technical scheme is: described blow down valve is fixedly mounted on cabinet。
Sampling valve and blow down valve are all fixedly mounted on cabinet, and the position of each valve is fixed, it is simple to operation。
The beneficial effects of the utility model are: be provided with purging pipeline and blow down valve, purge pipeline to be connected with outdoor by blow-down pipe, when gas circuit purges, close sampling valve, open blow down valve, purge pipeline gas and be discharged into outdoor by blow-down pipe, when pick test operates, close blow down valve, open sampling valve, sample gas enters analytical tool and carries out composition detection, thus reaching to purge gas be not discharged into the purpose in analysis room。Easy and simple to handle, and avoiding sample gas, to be discharged into the indoor oxygen content that indoor cause too high or too low, eliminates safe hidden trouble。
Accompanying drawing explanation
Fig. 1 is the structural representation of laboratory valve cabinet in prior art；
Fig. 2 is the structural representation of this utility model embodiment。
In figure: 1 cabinet, 2 sampling pipes, 3 sampling valves, 4 purge pipeline, 5 blow down valves, 6 blow-down pipes。
Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment, the utility model will be further described:
As shown in Figure 2。The space division gas analysis purging gas can be arranged outward and concentrate sampling cabinet, including cabinet 1, being set side by side with some sampling pipes 2 in cabinet 1, sampling pipe 2 one end is sample gas inlet, and sampling pipe 2 other end is sample gas outlet, sampling pipe 2 is provided with sampling valve 3, described sampling pipe 2 is provided with purging pipeline 4, purges pipeline 4 one end and be connected with sampling pipe 2, purge pipeline 4 other end and be connected with blow-down pipe 6, blow-down pipe 6 one end is closed, and blow-down pipe 6 other end leads to outdoor；Purge the connectivity points of pipeline 4 and sampling pipe 2 between sample gas inlet and sampling valve 3, purge pipeline 4 and be provided with blow down valve 5。
Described purging pipeline 4 is connected by three way cock with sampling pipe 2, and it is internal that the blind end of blow-down pipe 6 is positioned at cabinet 1, and sampling valve 3 and blow down valve 5 are all fixedly mounted on cabinet 1, and the position of each valve is fixed, it is simple to operation。
For ease of to understanding of the present utility model, below in conjunction with its use procedure, the utility model will be further described:
First, the sample gas inlet of sampling pipe 2 is connected the source of the gas of sample gas, the analysis mouth of the sample gas outlet linking parsing instrument of sampling pipe 2。
When being sampled checked operation, closing blow down valve 5, open sampling valve 3, every kind of sample gas analyzing gas enters analytical tool by sampling pipe 2 and carries out composition detection；When gas circuit purges, close sampling valve 3, open blow down valve 5, purge gas and enter blow-down pipe 6 through purging pipeline 2, then pass through blow-down pipe 6 and be discharged into outdoor。
The foregoing is only preferred embodiment of the present utility model; it it is not whole embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle; any amendment of being made, equivalent replacement, improvement etc., should be included within protection domain of the present utility model。
