Description
Technical field
Present invention relates particularly to a kind of experiment pipeline leakage testing devices.
Background technology
Because pipeline transportation has the characteristics that good leak tightness, freight volume are big, loss is small, is not easy to be influenced by extraneous factor,
As the preferred manner of petroleum transportation.It generally requires to demonstrate pipe leakage in experimental modelling, but existing experiment
Device, complicated, cost is higher.
Invention content
The purpose of the present invention is to provide a kind of simple in structure, experiment pipeline leakage testing devices of simple operation.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of experiment pipeline leakage testing device, packet
Include first pressure sensor, second pressure sensor, comparator, central processing unit, serial port module, PC machine, relay, leakage are opened
It closes, alarm module and input module, the first pressure sensor and second pressure sensor are connect with comparator, the ratio
It is connect respectively with central processing unit compared with device, alarm module and input module, the central processing unit passes through serial port module and PC machine
Connection, the central processing unit are connect by relay with leakage switch.
A kind of experiment pipeline leakage testing device as described above further illustrates to be that the central processing unit uses
The minimum system of AT89C51 chips and its peripheral circuit composition.
A kind of experiment pipeline leakage testing device as described above further illustrates to be that the alarm module uses sound
Light crossing-signal.
The beneficial effects of the invention are as follows：The present apparatus disclosure satisfy that experimental modelling needs, the leak detection of complete twin conduit, together
When the apparatus structure it is simple, it is of low cost, it is easy to spread, have good practicability.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Embodiment of the present invention is further elaborated below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of experiment provided by the invention is with pipeline leakage testing device, including first pressure sensor,
Second pressure sensor, comparator, central processing unit, serial port module, PC machine, relay, leakage switch, alarm module and input
Module.
The first pressure sensor and second pressure sensor are connect with comparator, the comparator, alarm module
It is connect respectively with central processing unit with input module, the first pressure sensor and second pressure sensor when mounted, divide
Not An Zhuan pipeline both ends, complete to the detection of the pressure values of pipe ends, the comparator is used for first pressure sensor
It is compared with the pressure signal of second pressure sensor acquisition, when pressure at two ends value is more than setting value, that is, represents pipeline hair
Life leakage, while comparator sends control signal to central processing unit, the central processing unit is using AT89C51 chips and its outside
The minimum system of circuit composition is enclosed, the chip structure is simple, low in energy consumption, is very suitable for present apparatus use.
The alarm module is for sending out alarm, suggesting effect, when leakage alarm module action occurs for pipeline, as
It is preferred that the alarm module uses audible-visual annunciator.The input module instructs for input control, and the input module can be with
Select keyboard.
The central processing unit is connect by serial port module with PC machine, so as to fulfill logical between central processing unit and PC machine
Letter connection.The central processing unit is connect by relay with leakage switch, so as to when being tested, be opened by opening leakage
It closes, leaks pipeline, so as to fulfill the pipeline leakage testing of the device.The present apparatus disclosure satisfy that experimental modelling needs, complete
The leak detection of twin conduit, while the apparatus structure is simple, it is of low cost, it is easy to spread, there is good practicability.
The present invention is not limited to examples detailed above, in claims of the present invention limited range, art technology
The various deformations or amendments that personnel can make without creative work are protected by this patent.
