Description
Technical field
The present invention relates to a kind of gas switching cabinet, be specifically related to a kind of quantitative gas automatic switching cabinet.
Background technology
Switching cabinet is used exclusively for the device of gas supply, this device to ensure uniformity and the seriality that gas supplies, also to ensure that output gas is voltage stabilizing state, and will not be not enough so that the hypotony in steel cylinder causes being switched to another road because of the excessive gas vaporization amount caused in steel cylinder of output flow, make the gas of interior of steel bottle use and only do not cause great waste.For meeting current user demand, the accuracy of switching cabinet and stability and the safety of gas output are proposed higher requirement, but all there is serious defect in the problems referred to above in existing switching cabinet, above-mentioned requirements cannot be met, in actual production process, in order to avoid affecting production owing to steel cylinder amount of vaporization is not enough, because the gas in steel cylinder uses the expenditure only not greatly improving enterprise, have a strong impact on business capital operating, it is necessary to improve.
Summary of the invention
For making up the deficiencies in the prior art, the present invention provides a kind of simple to operate, easy to use, the quantitative gas automatic switching cabinet of saving gas.
The present invention is achieved through the following technical solutions:
A kind of quantitative gas automatic switching cabinet, it is characterized in that and includes main line and the A pipe-line system connected with main line respectively, B pipe-line system and C pipe-line system, and described main line is connected to Electronic mass flow meter；Described A pipe-line system, B pipe-line system and C pipe-line system all include the gas input valve door, pressure transmitter and the electromagnetic valve that are sequentially connected with by pipeline；Described A pipe-line system, B pipe-line system and C pipe-line system and Electronic mass flow score are not connected with PLC.
The quantitative gas automatic switching cabinet of the present invention, is respectively connected with one way stop peturn valve between described A pipe-line system, B pipe-line system and electromagnetic valve and the main line of C pipe-line system.
The quantitative gas automatic switching cabinet of the present invention, described A pipe-line system, B pipe-line system and C pipe-line system are provided with bypass line respectively between pressure transmitter and main line, and bypass line is provided with bypath valve.
The quantitative gas automatic switching cabinet of the present invention, is provided with pressure regulator valve between described Electronic mass flow meter and main line.
The invention has the beneficial effects as follows: the automatic switching cabinet of the present invention can realize gas efficiently, accurately and automatically switch, can remotely control, simple to operate, easy to use, the stability and the safeties that export its gas have high guarantee, make the gas often organized in steel cylinder fully use simultaneously, reduce the waste of gas, be greatly saved fund and manpower.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present invention.
In figure, 1 main line, 2A pipe-line system, 3B pipe-line system, 4C pipe-line system, 5 Electronic mass flow meters, 6 pressure regulator valves, 7 gas input valve doors, 8 pressure transmitters, 9 one way stop peturn valves, 10 electromagnetic valves, 11 bypath valves, 12 bypass lines.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Accompanying drawing is a kind of detailed description of the invention of the present invention.This embodiment includes main line 1 and the A pipe-line system 2, B pipe-line system 3 and the C pipe-line system 4 that connect respectively with main line 1, and described main line 1 is connected to Electronic mass flow meter 5；Described A pipe-line system 2, B pipe-line system 3 and C pipe-line system 4 all include gas input valve door 7, pressure transmitter 8 and the electromagnetic valve 10 and the one way stop peturn valve 9 that are sequentially connected with by pipeline；A pipe-line system 2, B pipe-line system 3 and C pipe-line system 4 are provided with bypass line 12 respectively between pressure transmitter 8 and main line 1, and bypass line 12 is provided with bypath valve 11；It is provided with pressure regulator valve 6 between described Electronic mass flow meter 5 and main line 1；Described A pipe-line system 2, B pipe-line system 3 and C pipe-line system 4 and Electronic mass flow meter 5 are connected with PLC respectively.
The present embodiment by A, B, C tri-road gas with various pipeline switch over according to integrated flow.
Supply gas first by A pipe-line system 2, A pipe-line system 2 under normal circumstances, the bypath valve 11 of B pipe-line system 3 and C pipe-line system 4 is closed, after system power transmission, by the program that PLC sets, PLC reads the pressure value of A road intake line by the pressure transmitter 8 of A pipe-line system 2, opening electromagnetic valve 10 when gas pressure PLC when satisfied use pressure requirements of A road intake line allows A pipe-line system 2 first supply, Electronic mass flow meter 5 starts to measure the instantaneous delivery of supply, it is transferred to PLC, the supply integrated flow of PLC internal calculation A pipe-line system 2 gas, as integrated flow >=50m3Time, at gas pressure electromagnetic valve 10 of PLC closedown A pipe-line system 2 when satisfied use pressure requirements of B pipe-line system 3,10 the A road gases of electromagnetic valve opening B pipe-line system 3 are switched to B road gas supply.
After B pipe-line system 3 starts supply, PLC automatically switches to the supply integrated flow calculating B pipe-line system 3 gas, as integrated flow >=50m3Time, at gas pressure electromagnetic valve 10 of PLC closedown B pipe-line system 3 when satisfied use pressure requirements of C pipe-line system 4,10 the B road gases of electromagnetic valve opening C pipe-line system 4 are switched to C road gas supply.
After C pipe-line system 4 starts supply, PLC automatically switches to the supply integrated flow calculating C pipe-line system 4 gas, as integrated flow >=50m3Time, again switching to A pipe-line system 2 and supply, circulation is gone down successively.
When under power down mode, can supply by the bypath valve 11 on manual unlocking bypass line 12.One way stop peturn valve 9 is to prevent the gas of pipeline in supply from entering into the check device in non-supply air line by main line 1, makes Electronic mass flow meter 5 record the flow value of each road supply air line more accurately after installing this device.
