Specific embodiment
The embodiment of the utility model is illustrated below in conjunction with the accompanying drawings, embodiment does not form the limit to the utility model
System：
A kind of new chromatographic pipeline gas circuit, which is characterized in that comprising between gas cylinder, also comprising between the chromatography on side between gas cylinder,
Pipeline is extended with comprising multiple gas cylinders 5, multiple gas cylinders 5 between gas cylinder, pipeline is connected to chromatograph 3；The outlet of the gas cylinder includes
High-pressure spiral-coil 10, the high-pressure spiral-coil 10 are connected to pipeline, switch valve are included on pipeline.The technical solution at this place is played
Essence technique effect and its realize process be as follows：In order to facilitate replace gas cylinder, from above-mentioned gas cylinder connector to regulating valve it
Between should be equipped with high voltage bearing high-pressure spiral-coil；Therefore gas cylinder is convenient for changing, avoids interface pressure great change, cause insecurity.
Place one-level pressure relief valve in the bottle exit of the gas cylinder.Two level is provided with before being chromatograph before gas point of use
Pressure reducing valve.The technique effect and its realization process for the essence that the technical solution at this place is played are as follows：Due to gas cylinder internal
Gas pressure is for 20-25MPa or so, and the pressure of point of use is smaller, and gas pressure changes, and numerical difference is away from larger, therefore should
One-level pressure relief valve is placed in bottle exit.Second depressurized valve is set before gas point of use.
As a further improvement：
Primary colors spectrum gas circuit pipeline is removed and rearranges new air-channel system.
The steam line design of chromatography room is using 316L import stainless steel pipes.The manifold come between steel cylinder uses 1/2 "
Stainless Steel pipe, branch pipe use 1/4 " Stainless Steel pipe, stainless steel tube material be OCr18N；9, valve uses switch valve.Connection side
It is connected outside formula room using argon arc welding, interior is connected using cutting ferrule.Circuit design, Planning Points：Gas cylinder valve outlet is GB standards
External thread form (G5/8 "), connect for the ease of pipe-line system with gas cylinder, therefore exports to pipe-line system from bottle valve and should be equipped with and turn
Changing-over head (gas cylinder connector).It should be opened in the system of each gas equipped with the device one that in case of emergency can quickly cut off gas supply
Valve is closed, for the convenience of switching system and convenient, switch valve uses ball valve in this project.It replaces in order to prevent extraneous empty during gas cylinder
Gas enters pipe-line system, should set ball valve, and the ball valve blank pipe that is connected with evacuated tube should be reliably connected air, and imflammable gas is with helping
The evacuated tube of right property gas should be independent, and evacuated tube exit should install explosion-proof non-return valve additional to prevent the generation of tempering phenomenon.In the past
Chromatography gas circuit there are security risk, these problems are not present after being now transformed in high-purity gas loss.
With reference to Fig. 2, multiple grooves are included with the gas cylinder sheet, can be coiled in groove and place hose.The technology at this place
The technique effect and its realization process for the essence that scheme is played are as follows：Hose can be placed in groove, further such that carrying
When gas cylinder, if there is pipeline, without walking in tow, which facilitates receiving and arrangement.
Molecular sieve is also connected on the pipeline.Combustible gas alarming instrument is disposed between the chromatography.6 tunnel of main line
(Ar.N2.Air.H2.O2) through being laid between steel pipe along wall, into laboratory metope installation function column, through functional column reducing 1/4 "
Pipe is laid along ground after testing stand to 10 gas-chromatography testing stands, and installs ball valve additional, and each testing stand summarizes 1/4 " emptying all the way
Pipe, lays along wall to outdoor.It is fixed (3) safely that (1) component material of inspecting for acceptance meets all tie points of national standard material (2)
Layout of beam line is reasonable, beautiful.(4) gas label is pasted correctly, is beautiful.(5) correct (6) pressure test of pipeline connection：In pipe
High N2 (99.999%) is filled in road system, pressure is equal with operating pressure, pressurize estimate within 24 hours all components without fracture and
Deformation, pipe fixing bracket and pipe clamp non-loosening and the generation that comes off.(7) pressure fall-off test：High-purity N 2 is filled in pipe-line system
(99.999%), pressure is 1.5 times of operating pressure, and after pressurize 24 hours, pressure gauge reading variation is less than 0.25%.(8) it lets out
Test leakage tries：High-purity N 2 (99.999%) is filled in pipe-line system, pressure is 1.5 times of work, is connected in all not parts of system
It meets place and smears special leak detection liquid, checking whether there is bubble every 5min generates, this test tests process and continues 30 minutes.For the ease of
Repair and replacement valve member, while ensure the air-tightness of system, the connection of pipeline and valve member should use high pressure double card bell and spigot joint to connect
It connects.
In a creative way, each effect is individually present more than, moreover it is possible to the combination of the above results is completed with a nested structure.
It is clear that the technique effect that more than structure is realized is realized, discounting for additional technical solution, this patent title is also
It can be a kind of new chromatographic pipeline.It is not shown in figure part details.
It should be noted that multiple schemes that this patent provides include the basic scheme of itself, independently of each other, not mutually
It restricts, but it can also be combined with each other in the absence of conflict, reach multiple effects and realize jointly.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.Ability
The technical staff in domain should be recognized that the present utility model is not limited to the above embodiments, described in the above embodiment and specification
Only illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model can also
There are various changes and modifications, these changes and improvements are both fallen in claimed range.
