Technical field
This utility model belongs to cryogenic liquid sampler, particularly relates to the sampler of medical liquid oxygen.
Background technology
Medical oxygen is as Drug Administration, and the inspection to the most various indexs is the strictest.By cryogenic refrigeration method produce the liquid oxygen produced through inspection qualified up to standard after, can use as medical oxygen.At present, more to the Medical liquid oxygen product inspection contents of a project, mainly include five qualitative and quantitative analyses such as oxygen content, acid-base value, carbon monoxide, carbon dioxide, other gaseous oxidizing species.Owing to the Check-Out Time of every content is longer, therefore it is required that air velocity regime flow is constant.
Conventional medical oxygen inspection is that Dewar tank is the Stainless steel pressure vessels using super vacuum insulation, is used for storing, transport and use the cryogenic liquids such as liquid oxygen, liquid nitrogen, liquid argon by the liquid oxygen sampling in medical liquid oxygen storage tank or outside transport container to Dewar tank.Behind Dewar pot extremely medical liquid oxygen dedicated analysis room, connect analytical tool, utilize its built-in gasifier to export room temperature gaseous oxygen, and meet flow and the pressure of inspection sample gas by regulating various valves on it.Problems Existing is: first, and Dewar tank is heavier, and the Dewar tank of 10 liter capacities adds own wt after being full of liquid oxygen, and a people carries gruelling, and what volume was bigger typically requires mechanical handing, the most very inconvenient；Secondly because cost and space reasons, and the often replacing of sample gas needs, so it is the most uneconomical to be equipped with multiple Dewar tank simultaneously, too increase carrying difficulty simultaneously；It addition, usual only a set of outlet device on a Dewar tank, can only complete every inspection content during use one by one, multiple inspection projects cannot be carried out simultaneously, also needs to frequently more alias according to the difference of inspection project, and complex operation is the longest.Additionally, there is certain potential safety hazard in manual operation sampling.
Summary of the invention
For solving technical problem present in above-mentioned medical liquid oxygen sampling process, following improvement made by existing sampler by this utility model:
The sampler of a kind of medical liquid oxygen of this utility model, this device includes sampling total pipeline, multichannel sampling branch pipe(tube), medical oxygen analytical tool；Sampling total pipeline connects and is provided with control valve with the device equipped with medical liquid oxygen, sampling total pipeline is connected with the multichannel sampling branch pipe(tube) arranged side by side set within it by multiple-pass joint after entering in medical liquid oxygen analysis room, sampling branch pipe(tube) connects medical oxygen analytical tool, and sampling branch pipe(tube) in every road is both provided with controlling accordingly valve.Wherein, the device of the medical liquid oxygen of device is medical liquid oxygen storage tank or external transport container.
Specifically: device described in the utility model: be that directly the gasification position from medical liquid oxygen storage tank or external transport container picks out a road sampling total pipeline, described pipeline is introduced medical liquid oxygen analysis room, described sampling line controls pipeline and is switched on or switched off by arranging shutoff valve；Sampling total pipeline can also be merged into after two or above sampling pipe being connected with threeway or manifold mode simultaneously, access medical liquid oxygen analysis room, sampling total pipeline arranges shutoff valve；Multiple-pass joint can be selected afterwards according to the inspection number of entry, the pipeline choosing identical caliber is connected with multiple-pass joint respectively, form each sampling branch pipe(tube), more each sampling branch pipe(tube) is connected with medical oxygen analytical tool side by side, need various control valve is installed according to scene simultaneously on each sampling arm.
In order to reach the sampling pressure that medical oxygen analytical tool requires more accurately, described sampling total pipeline is provided with pressure monitoring instrument.
In the case of multiple sampling sources, in order to the most convenient to operate, described sampling total pipeline is provided with cut-off total valve.
For the ease of each inspection project individually being controlled its operation, sampling branch pipe(tube) in described every road being configured with Valve controlling pipeline and is switched on or switched off, and regulating sampling medium flow and pressure size.
In order to the most accurately reach the pressure required by medical oxygen analysis and flow, described every road branch pipe(tube) is configured with traffic monitor instrument, according to monitoring that the valve on described branch pipe(tube) is adjusted controlling by numerical value.
Than existing sampler, practicality of the present utility model is: 1, medical oxygen analytical tool is directly connected with sampling source, eliminates the manual operation in sampling process, the problem i.e. solving difficult, also improves the safety of operating process simultaneously；2, can link together management by multiple sampling sources, simplifies manual sampling attended operation program；3, use the mode of branch's sample introduction, the required entries purpose inspection can be carried out simultaneously, it is simple to each controls, and saves Check-Out Time, improves checkability.4, branch's sampling carries out pressure and flow-control simultaneously, can meet the pressure required for every inspection project and flow, reaches the effect of constant pressure and flow, improves precision of analysis.

Detailed description of the invention
1 pair of a kind of medical liquid oxygen sampler of this utility model is further described below in conjunction with the accompanying drawings.
In the present embodiment, as shown in Figure 1, described device includes drawing sampling total pipeline from the liquid oxygen gasification room of medical liquid oxygen storage tank 1 and external transport container (such as tank car) 5, connected by threeway and form the medical liquid oxygen analysis room 11 of sampling total pipeline access, practical operation can connect a plurality of sampling branch pipe(tube) according to field demand；The sampling line drawn from medical liquid oxygen storage tank 1 controls it be switched on or switched off by arranging the first stop valve 2, and the sampling line drawn from external transport container (such as tank car) 5 controls it be switched on or switched off by arranging the second stop valve 4；The total pipeline that two-way sampling line converges into arranges the 3rd stop valve 6, is used for controlling to sample gaseous oxygen and enters connection or the disconnection of medical liquid oxygen analysis room 11；For ease of pressure monitor, Pressure gauge 3 is set before the 3rd stop valve 6, regulates the first stop valve 2 or aperture of the second stop valve 4 according to the numerical value of Pressure gauge 3.After sampling total pipeline introduces medical liquid oxygen analysis room 11, choose five-way joint according to the inspection number of entry, the pipeline of five identical calibers is connected with five-way joint, form five tunnel sampling branch pipe(tube)s arranged side by side, be respectively connected to medical oxygen analytical tool 10.In order to control flow and pressure further, meet flow and the force value of every inspection needs, sampling branch pipe(tube) in every road is separately installed with branch's stop valve 7, branch's air relief valve 8 and affluent-dividing gauge 9 successively, can to wherein several or test respectively as required during inspection simultaneously.
This utility model substitutes the sampled functions of Dewar tank by the way of arranging sampling line at the scene, the problem not only solving Dewar pot difficulty, significantly shorten Check-Out Time simultaneously, effectively simplifies operation sequence, decreases a large amount of manual steps；Secondly, the setting of multiple valve and monitoring, improve the safety in sampling process, decrease the probability that there is error in manual operation.
