Description
Technical field
A kind of instrument air system using purified air, belongs to space division system technical field.
Background technology
Total system instrument air is supplied by J2002 instrument airs compressor, because instrument air compressor fails to reach preferable
Oil-gas Separation state, thus cause instrument air on a small quantity band oil, directly influence the control accuracy of regulating valve, while also shorten
Valve service life.
The content of the invention
What the technical problems to be solved by the invention were to provide that a kind of purified air substitutes air compressor instrument air is
System.
In order to solve the above technical problems, the technical solution adopted in the present invention：A kind of instrument air using purified air
System, including air compressor, instrument air A storage tanks, oil expeller, regenerative dryer, instrument air B storage tanks, instrument air pipe
Net, purified air pipe arrangement, the first gate valve, the second gate valve；
The air compressor, instrument air A storage tanks, oil expeller, regenerative dryer, instrument air B storage tanks connect from beginning to end successively,
And shut-off valve is equipped between any two in instrument air A storage tanks, oil expeller, regenerative dryer, instrument air B storage tanks, in oil removing
Device is front and rear, is additionally provided with bypass valve before and after regenerative dryer, and the instrument air B storage tanks are connected with instrument air pipe network, and
Shut-off valve is equipped between instrument air B storage tanks and instrument air pipe network；
The purified air pipe arrangement connects after the first gate valve, the second gate valve successively with instrument air pipe network, and the
Showering guilding valve is equipped between one gate valve, the second gate valve.
Purified air in the purified air pipe arrangement is the purified air of external device (ED).
Compared to the prior art the present invention has the advantages that.
First, the present invention substitutes the instrument air of air compressor offer by purification system, stablizes fortune maintaining each workshop section
It not only avoid instrument air a small amount of situation with oil while row, it is empty to also reduce the instrument brought using air compressor
The gas storage tank pressurising time, and valve operation control accuracy is also improved, extend the service life of valve.
2nd, the present invention does not supply at once, can be switched to the instrument air that air compressor provides when purified air, by instrument
The of short duration maintenance of air reservoir, strong applicability.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
In figure, 1 is air compressor, and 2 be instrument air A storage tanks, and 3 be oil expeller, and 4 be regenerative dryer, and 5 is empty for instrument
Gas B storage tanks, 6 be instrument air pipe network, and 7 be purified air pipe arrangement, and 8 be the first gate valve, and 9 be the second gate valve, and 10 be bypass valve.
Embodiment
As shown in Figure 1, a kind of instrument air system using purified air, including air compressor 1, instrument air A storage
Tank 2, oil expeller 3, regenerative dryer 4, instrument air B storage tanks 5, instrument air pipe network 6, purified air pipe arrangement 7, the first gate valve 8,
Second gate valve 9；
The air compressor 1, instrument air A storage tanks 2, oil expeller 3, regenerative dryer 4, instrument air B storage tanks 5 successively head and the tail
Connection, and cut-off is equipped between any two in instrument air A storage tanks 2, oil expeller 3, regenerative dryer 4, instrument air B storage tanks 5
Valve, before and after oil expeller 3, is additionally provided with bypass valve 10, the instrument air B storage tanks 5 and instrument air pipe before and after regenerative dryer 4
Net 6 connects, and shut-off valve is equipped between instrument air B storage tanks 5 and instrument air pipe network 6；
The purified air pipe arrangement 7 connects after the first gate valve 8 successively, the second gate valve 9 with instrument air pipe network 6, and
Showering guilding valve is equipped between the first gate valve 8, the second gate valve 9.
Purified air in the purified air pipe arrangement 7 is the purified air of external device (ED).
The present invention is to add purified air pipe arrangement 7 and relevant first gate valve 8, the second gate valve compared with prior art
9, can be that instrument air pipe network 6 provides purified air.
The present invention operating process be：When being switched to the work of purified air pipe arrangement 7, first should be checked before activation first
Whether gate valve 8, the second gate valve 9 close, and whether 9 the first gate valve 8, the second gate valve showering guilding valves are opened, when normal operation of the present invention
Purified air pipe arrangement 7 is switched to again afterwards to work.And 6 pressure of instrument air pipe network is needed to be down to after air compressor 1 is stopped
500Kpa opens the first gate valve 8, the second gate valve 9 again, simultaneously closes off 9 the first gate valve 8, the second gate valve showering guilding valves, should also at this time
Oil expeller 3 and the bypass valve 10 of regenerative dryer 4 are opened, to ensure instrument air pressure of storage tank so that in case of emergency instrument
Table air reservoir can be that instrument air pipe network 6 supplies.
Equally, when be switched to air compressor 1 work when, should air compressor 1 startup after close the first gate valve 8,
Second gate valve 9, while open 9 the first gate valve 8, the second gate valve showering guilding valves, then open instrument air A storage tanks 2, oil expeller 3,
The front and rear shut-off valve of regenerative dryer 4, instrument air B storage tanks 5, and close oil expeller 3 and the bypass valve 10 of regenerative dryer 4.
Above-described embodiment is the explanation to structure of the present invention and unrestricted, is made without departing from the principles of the present invention
Deformation is also within protection scope of the present invention.
