Technical field
The present invention relates to a kind of standard oil samples suitable for oil dissolved gas on-Line Monitor Device field calibration to switch dress
It sets.
Background technique
Oil dissolved gas on-Line Monitor Device is needed because long-time service causes performance to decline at the scene by using standard oil
Sample is calibrated.The sensor that oil dissolved gas on-Line Monitor Device uses is mostly nonlinear transducer, and field calibration is usual
It is tested using basic, normal, high or more various concentration standard oil sample rotations, in various concentration standard oil sample rotation test process,
Tester is after completing the test of first oil sample, then disconnects pipeline, connects another concentration oil sample, carry out pipeline switching,
It rinses, pipeline need to be switched repeatedly using tester when multiple oil samples, cause on-the-spot test low efficiency, period long, switch by hand
Pipeline is easy error, and then causes oil sample cross contamination.If handoff procedure carries out at night, on-the-spot test personnel can will be given
Cause bigger puzzlement.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of standard oil sample switching device, exists for oil dissolved gas
The field calibration of line monitoring device can be reduced Field Force's working strength, improve calibration the degree of automation.
To achieve the above object, the technical solution of the present invention is as follows:
A kind of standard oil sample switching device, for multiple standard oil sample holding vessels and oil dissolved gas on-Line Monitor Device
Connection, including connecting pipe and the multiple taps, multiple control valves, the two total connectors and two that are mounted in connecting pipe
The quantity of a fuel outlet valve, tap and control valve corresponds, and the oil outlet of each standard oil sample holding vessel passes sequentially through one
After a tap and a control valve, then the oil inlet phase through total a connector and oil dissolved gas on-Line Monitor Device
Even, the oil outlet of oil dissolved gas on-Line Monitor Device passes sequentially through a control valve after another total connector respectively
It is connected with a tap with the oil return opening of each standard oil sample holding vessel, fuel outlet valve is separately positioned on two total connectors far from oil
The side of dissolved gas on-Line Monitor Device.
By controlling the switch of control valve in each connecting pipe, can at least realize the standard oil samples of 2 kinds of various concentrations with
The connection switching being detected between oil dissolved gas on-Line Monitor Device, while can control the intersection after different oil sample switchings
Pollution.
Further, the control valve is manually-operated gate.
It further, further include control device, the control valve is the solenoid valve being electrically connected with control device.
Further, the control device is PLC or timer, by PLC control or timing controlled, between pipeline
Connection and close can be achieved automation, improve work on the spot efficiency.
Further, the connecting pipe is stainless steel tube, copper pipe or polyfluortetraethylene pipe, and oil sample can be effectively prevented
The generation of leakage problem.
Further, the tap and total connector are all made of variable diameter quick coupling, to realize between different pipelines
Quick connection.
Compared with the prior art, the invention has the following advantages:
1, by the switch of the control valve in control connecting pipe, the standard oil sample of 2 kinds of various concentrations can be at least realized
Connection switching between detected oil dissolved gas on-Line Monitor Device.
2, using the control valve in PLC or Timer Controlling connecting pipe, the connection between oil circuit can be real with closing
It now automates, improves work on the spot efficiency.
3, the standard oil sample of various concentration can realize oil return, reduce the use of standard oil sample；By controlling fuel outlet valve, may be used also
To realize not oil return.
4, by control fuel outlet valve switch time, the function that pipe flushing is carried out using a small amount of standard oil sample may be implemented,
It can avoid the cross contamination between different oil samples.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of standard oil sample switching device of the present invention；
Description of symbols: 1- standard oil sample holding vessel；2- tap；3- control valve；4- fuel outlet valve；The total connector of 5-；
6- oil dissolved gas on-Line Monitor Device.
Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
As shown in Figure 1, a kind of standard oil sample switching device, is used for multiple standard oil sample holding vessels 1 and oil dissolved gas
