Abstract
The utility model discloses an automatic gas path converter which comprises left and right gas inlets. The left and right gas inlets are connected with a gas cylinder and are respectively connected with interrelated pressure conversion valves through pipelines; the pressure conversion valves are communicated with an output end pressure control valve through pipelines; and the output end pressure control valve is connected with a gas output port. The automatic gas path converter adopts the double-gas path supply method, when one path gas is used up, the converter can automatically convert to the standby gas path, corresponding pressure gauges and gas path work indicators are used for prompting, the user can implement online gas cylinder replacement, and the uninterrupted gas supply of the instrument can be truly realized.
Description
Technical field
The utility model relates to a kind of transducer, particularly a kind of automatic gas path transducer.
Background technique
At present normally adopt single gas cylinder plenum system on the laboratory apparatus, when gas cylinder gas exhausts, have to interrupt the instrument air feed, thereby make troubles and lose to real work because of changing gas cylinder.Though also have few user to adopt existing two gas air feed now, it need manually carry out gas circuit and switch, price is also more expensive, popularizes employing so be difficult to the user.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of automatic gas path transducer.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of automatic gas path transducer, two suction ports that connect gas cylinder about it comprises, left and right sides suction port is connected with the pressure changeover valve that is mutually related respectively by pipeline, and pressure changeover valve communicates with the output end pressure modulating valve by pipeline, and the output end pressure modulating valve is connected with gas delivery port;
As above-mentioned mode of execution is improved, be respectively arranged with pressure gauge on the described suction port; Be respectively arranged with operation indicator on the described pressure changeover valve;
As the further improvement to above-mentioned mode of execution, described output end pressure modulating valve is provided with the gas output pressure table.
The beneficial effects of the utility model are: the utility model is two gas circuit plenum systems, when using up, one road gas can be converted to standby gas circuit automatically, and relevant pressure table and the prompting of gas circuit operation indicator are arranged, the user can carry out online replacing gas cylinder, thereby really realizes the uninterrupted air feed of instrument.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a gas circuit skeleton diagram of the present utility model.
Embodiment
With reference to Fig. 1, a kind of automatic gas path transducer, two suction ports 1,2 that connect gas cylinder about it comprises, left and right sides suction port 1,2 is connected with the pressure changeover valve 3,4 that is mutually related respectively by pipeline, pressure changeover valve 3,4 communicates with output end pressure modulating valve 5 by pipeline, output end pressure modulating valve 5 is connected with gas delivery port 6, and gas delivery port 6 is connected with instrument.
This product is understood the use condition of left and right sides gas cylinder for convenience, be respectively arranged with pressure gauge 7,8 on the described suction port 1,2, in addition, also be respectively arranged with operation indicator 9,10 on the described pressure changeover valve 3,4, simultaneously, described output end pressure modulating valve 5 is provided with gas output pressure table 11.
The working principle of this product is: the gas cylinder that is connected when left suction port 1 is during at air feed, and the pressure changeover valve 3 control gas circuits that are attached thereto are opened 9 work of gas circuit operation indicator; Pressure changeover valve 4 control gas circuits are ended simultaneously, and corresponding gas circuit operation indicator 10 is not worked.
When the gas of gas cylinder that left suction port 1 connects is used up or gas pressure when reducing to reduced levels, the pressure changeover valve 3 control gas circuits that are attached thereto are ended, corresponding gas circuit operation indicator 9 quits work, and pressure changeover valve 4 control gas circuits are opened simultaneously, 10 work of gas circuit operation indicator.
The utility model is two gas circuit plenum systems, can be converted to standby gas circuit automatically when one road gas is used up, and relevant pressure table and the prompting of gas circuit operation indicator are arranged, and the user can carry out online replacing gas cylinder, thereby really realizes the uninterrupted air feed of instrument.
