Abstract
The utility model discloses an air distributing device adding corrosive air from a bypass. The air distributing device comprises a main pipeline; one end of the main pipeline is connected with a raw material air steel cylinder joint, and the other end is connected with a finished air steel cylinder joint; a first valve is connected between the raw material air steel cylinder joint and the finished air steel cylinder joint; a second valve, a third valve and a fourth valve are connected between the first valve and the steel cylinder joints; the second valve is connected with an empty pipe; a third valve is connected with a low-pressure pressure meter; and the fourth valve is connected with an air source main device. The air distributing device is simple in structure, the pipeline is convenient to clean, time and manpower are saved, and the air distributing device is safe and convenient to use.
Description
Technical field
The utility model relates to a kind of air distributing device, and particularly a kind of corrosive gas bypass adds air distributing device, for configure various gas in steel cylinder.
Background technique
It is very numerous and diverse that Standard Gases is produced the gaseous species comprising, and normally all chemical substances that can gasify can be formulated in Standard Gases, and this wherein just has many corrosive gass.Corrosive gas refers to the gas with very strong acidity, alkalescence, oxidability, can form Eroded to the inner-walls of duct of air distributing device, or be adsorbed on tube wall, and other kind Standard Gases of device preparation is exerted an influence.Under current condition, be generally after device preparation overetching gas, pipeline is cleaned, but because the pipeline more complicated of air distributing device was cleaned and is also difficult to produce a desired effect, after a period of time, will on inner-walls of duct, accumulate and form dirt, Standard Gases is produced and produced greatly impact.Standard Gases is produced turbidity test to air distributing device pipeline inner wall, adsorptivity and is required very highly, can only regularly replace at present whole pipelines, has greatly improved so again cost of production.The preparation of corrosive gas is the difficult point that Standard Gases is produced always.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, detergent line convenient, corrosive gas bypass time saving and energy saving, safe ready adds air distributing device, overcomes the deficiencies in the prior art.
Corrosive gas bypass of the present utility model adds air distributing device, comprise main line, one end of main line is connected to virgin gas joint, the other end is connected to finished product gas cylinder joint, between virgin gas cylinder joint and finished product gas cylinder joint, be connected to the first valve, between the first valve and virgin gas cylinder joint, be connected to high-pressure manometer, between the first valve and finished product gas cylinder joint, be connected to the second valve, the 3rd valve, the 4th valve, the second valve connects blow-down pipe, the 3rd valve connects low pressure gauge, and the 4th valve and the main device of source of the gas join.
Corrosive gas bypass of the present utility model adds air distributing device, and whole main line only adopts a control valve, i.e. the first valve is controlled adding of corrosive gas.Other three indispensable valves be respectively connect low pressure gauge the 3rd valve, connect the second valve of blow-down pipe and lead to the 4th valve of the main device of source of the gas, working principle is easily understood.When distribution, close the second valve, the 3rd valve and the 4th valve, by the main device distribution of source of the gas, corrosive gas enters in finished product steel cylinder by virgin gas joint, the first valve, quantitatively adds finished product gas cylinder, after having operated with pressure gauge, close virgin gas and finished product gas cylinder valve, open the second valve and utilize blow-down pipe emptying, then control the pipeline nitrogen blowing displacement that main device connects, after having replaced, vacuumize with the vacuum equipment of main device, carry out adding of subsequent component.Simple in structure, detergent line is convenient, time saving and energy saving, safe ready.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: 1 is casing, 4 for being configured in the main line in casing 1, the two ends of main line 4 all extend out to the outside of casing 1, and one end is connected to virgin gas cylinder joint 2, the other end is connected to finished product gas cylinder joint 5, between virgin gas cylinder joint 2 and finished product gas cylinder joint 5, be connected to the first valve 3, between the first valve 3 and virgin gas joint 2, be connected to high-pressure manometer 10, between the first valve 3 and finished product gas cylinder joint 5, be connected to the second valve 6, the 3rd valve 7, the 4th valve 8, the second valve 6 connects blow-down pipe 12 and stretches to casing outside, the 3rd valve 7 connects low pressure gauge 9, the 4th valve 8 joins with the main device 11 of source of the gas.
Corrosive gas bypass of the present utility model adds air distributing device, and whole main line only adopts a control valve, i.e. the first valve 3 is controlled adding of corrosive gas.Other three indispensable valves be respectively connect low pressure gauge 9 the 3rd valve 7, connect the second valve 6 of blow-down pipe 12 and lead to the 4th valve 8 of the main device 11 of source of the gas, working principle is easily understood.When distribution, close the second valve 6, the 3rd valve 7 and the 4th valve 8, corrosive gas enters in finished product steel cylinder by virgin gas cylinder joint 2, the first valve 3, finished product gas cylinder joint 5, quantitatively add finished product gas cylinder with pressure gauge, after having operated, close virgin gas and finished product gas cylinder valve, open the second valve 6 and utilize blow-down pipe 12 emptying, coordinate again the 4th valve 8 to control the pipeline nitrogen blowing displacement that the main device 11 of source of the gas connects, after having replaced, close the second valve 6, vacuumize with the vacuum equipment of the main device 11 of source of the gas, carry out adding of subsequent component.Simple in structure, detergent line is convenient, time saving and energy saving, safe ready.
