The three position five way valve (2) is connected with grounding (10) and the two absorbers (5) connected parallel are connected in series with a third absorber (5) provided with a pressure gauge (3). The device further comprises a nitrogen buffer tank. Flow limiting valves (4) are arranged between the nitrogen buffer tank and the primary two absorbers (5) respectively. The nitrogen buffer tank is connected with a check valve (7) through a flow meter (6) and the check valve (7) is connected with the nitrogen outlet (9). A ball valve (8) connected with a detection sampling opening (11) is connected between the check valve (7) and the nitrogen outlet (9). The utility model has the advantages of reducing the cost, simplifying the processes and is stable in product quality and the device is highly stable.
Description
Technical field
The utility model relates to a kind of device of producing nitrogen in the pipeline industry, particularly a kind of device of small-sized production nitrogen.
Background technology
Nitrogen is rare gas element, is widely used in fields such as aerospace, nuclear power nuclear energy, food medicine, petrochemical complex, electronic industry, material industry, defence and military and scientific experiment.As in automotive industry, nitrogen is better than air to the damage of wheel, and rapid heat dissipation, is not easy to blow out.
The process structure of conventional products is: system is connected on the air cushioning gas-holder by air pressurized air, through cushioning the air that dewaters; By the output of gas-holder top, get into the strainer dedusting again and dewater, be connected to cooling driers; Connect T level strainer and A level strainer then; Get into nitrogen separation equipment then, the nitrogen of separating connects the product gas surge tank, measures at last and analyzes.
The utility model content
To existing defective of producing nitrogen gas preparing, the utility model provides a kind of device of small-sized production nitrogen.
To achieve these goals, the measure taked of the utility model is:
A kind of device of small-sized production nitrogen; Comprise the gas inlet and the nitrogen outlet that are communicated with through pipeline, gas inlet is provided with manometric adsorber through three position five-way valve and two and is connected in parallel, and is connected with ground connection on the three position five-way valve; Be provided with manometric adsorber and be connected in series with the 3rd after two adsorber parallel connections; Also comprise nitrogen buffer tank, be provided with flow-limiting valve between nitrogen buffer tank and preceding two adsorbers, nitrogen buffer tank links to each other with vacuum breaker through under meter; Vacuum breaker links to each other with nitrogen outlet, is connected with between vacuum breaker and the nitrogen outlet and detects the ball valve that thief hole links to each other;
Said three position five-way valve is the integrated form guiding valve of automatically controlled power 3.5W;
The material of said vacuum breaker is PVC;
Said flow is counted glass rotameter.
The beneficial effect of the utility model: effectively reduce the manufacturing cost of nitrogen gas preparing, work simplification, and the constant product quality that obtains; The air intake valve of equipment adopts the integrated form guiding valve, automatically controlled power 3.5W, and independent control is controlled cost and is also declined to a great extent; The top nitrogen outlet adopts regulated valve to control gas, because work simplification, system's valve quantity reduces, and reducing the reference mark is 1, effectively reduces rate of occurrence of equipment failure; Improve stable equipment operation property.

Embodiment
A kind of device of small-sized production nitrogen; Comprise the gas inlet 1 and nitrogen outlet 9 that are communicated with through pipeline; Gas inlet 1 is connected in parallel through three position five-way valve 2 and two adsorbers 5 that are provided with tensimeter 3, is connected with 10, two adsorbers of ground connection, 5 parallel connection backs on the three position five-way valve 2 and is connected in series with the 3rd adsorber 5 that is provided with tensimeter 3; Be provided with flow-limiting valve 4 between nitrogen buffer tank and preceding two adsorbers 5; Nitrogen buffer tank links to each other with vacuum breaker 7 through under meter 6, and vacuum breaker 7 links to each other with nitrogen outlet 9, is connected with between vacuum breaker 7 and the nitrogen outlet 9 and detects the ball valve 8 that thief hole 11 links to each other; Said three position five-way valve 2 is the integrated form guiding valve of automatically controlled power 3.5W; The material of said vacuum breaker 7 is PVC; Said under meter 6 is a glass rotameter.
Get into ducted air successively through after three adsorbers; Can remove airborne oxygen, carbonic acid gas and moisture, obtain nitrogen, can pass through the purity of the nitrogen of detection thief hole through the control of ball valve; When purity is not high; Can be according to the tensimeter on the adsorber, the control flow-limiting valve reduces air flow quantity, thereby increases the concentration of output nitrogen.
The beneficial effect of the utility model: the nitrogen of separating is directly through two current limliting valve butt joints; By middle adapter output products nitrogen; Simplify technology, originally need installation two-bit triplet electric control valve and an adjusting to purge valve and use simultaneously and can be effective; Effectively reduce the manufacturing cost of nitrogen gas preparing, work simplification, and the constant product quality that obtains; The air intake valve of equipment adopts the integrated form guiding valve, automatically controlled power 3.5W, and independent control is controlled cost and is also declined to a great extent; The top nitrogen outlet adopts regulated valve to control gas, because work simplification, system's valve quantity reduces, and reducing the reference mark is 1, effectively reduces rate of occurrence of equipment failure; Improve stable equipment operation property.
Those skilled in the art's simple change and replacement all are within the protection domain of the utility model in this area.
