Description
Technical field
The present invention relates to high-low pressure sensor technical fields, and in particular to a kind of high-low pressure sensing with pressure indicating structure
Device.
Background technique
In the exploitation production process of oil gas field, since the pressure in oil/gas well is usually very high, it need to subtract by throttling layer by layer
Just pressure can be output to production flow line subsequently into treatment plant, in order to guarantee the safety of production flow line, need to set the high pressure of pipeline
Limit value and low pressure limit value, when line pressure exceeds limits, Yao Liansuo well head control panel is to well mouth release valve emergency shutdown.
However since the exploitation with well head is frequently encountered the setting value of scene adjustment height pressure sensor, and the existing pipeline in market
Height pressure sensor does not show the instruction device of pressure, need to be removed and be taken when needing to adjust pressure set points every time
It goes back to factory to adjust, test, so that adjustment setting value is very troublesome.
Summary of the invention
The object of the present invention is to provide a kind of height pressure sensor with pressure indicating structure, no longer to need to dismantle sensing
Device can accurately complete pressure adjusting.
In order to achieve the above objectives, the present invention provides a kind of height pressure sensor with pressure indicating structure comprising: it passes
Sensor ontology and screw press；The threaded hole with screw press cooperation is provided in the sensor body；The screw thread
Pressure spring is provided in hole；One end of the pressure spring is abutted against with sensor body, the other end and the screw press
It abuts against；Through-hole is provided in the sensor body of the pressure spring side；The instruction of pressure regulation pressure is provided on the through-hole to carve
Spend plate.
The above-mentioned height pressure sensor with pressure indicating structure, wherein be additionally provided with locking nut on the screw press.
The above-mentioned height pressure sensor with pressure indicating structure, wherein the pressure regulation pressure indicating graduation plate passes through spiral shell
Bolt is connect with the sensor body.
The above-mentioned height pressure sensor with pressure indicating structure, wherein the material of the pressure regulation pressure indicating graduation plate
For high-intensitive organic glass.
The above-mentioned height pressure sensor with pressure indicating structure, wherein be provided with pipeline in the sensor body and take
Press mouth.
The above-mentioned height pressure sensor with pressure indicating structure, wherein the pipeline pressure tappings are provided with external screw thread.
Compared with the existing technology, the invention has the following advantages:
The present invention has structure simple, easy to operate；Operation, maintenance cost are low, and failure rate is low；Numerical value is accurate, and sexual valence is very
High feature.The pressure setting of height pressure sensor provided by the present invention mainly reaches by adjusting its inside pressure spring
The adjustment of setting value can show pressure in the outer surface aperture and increase of sensor body according to the characteristic of spring pressure or pulling force
The pressure regulation pressure indicating graduation plate of power can reflect the setting value of pressure of height pressure sensor, so that scene adjustment pressure value
Operation becomes convenient, simple, and pressure scale is tested repeatedly by factory can reach very exact value.The present invention can be
In the case where not dismantling height pressure sensor, so that it may accurately complete pressure and adjust.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the height pressure sensor of the invention with pressure indicating structure.
Specific embodiment
Below in conjunction with attached drawing, by specific embodiment, the invention will be further described, these embodiments are merely to illustrate
The present invention is not limiting the scope of the invention.
As shown in Figure 1, the present invention provides a kind of height pressure sensor with pressure indicating structure comprising: sensor
Ontology 1 and screw press 2；The threaded hole with the screw press 2 cooperation is provided in the sensor body 1；The screw thread
Pressure spring 3 is provided in hole；One end of the pressure spring 3 is abutted against with sensor body 1, the other end and the pressure regulation spiral shell
Bar 2 abuts against；Through-hole is provided in the sensor body 1 of 3 side of pressure spring；Pressure regulation pressure is provided on the through-hole to refer to
Show scale plate 4, can the scale according to corresponding to the position after 3 deformation of pressure spring read adjust after setting value of pressure.Institute
It states and is provided with pipeline pressure tappings 6 in sensor body 1, for connecting the pipeline of pressure to be measured.The pipeline pressure tappings 6 are provided with outer
Screw thread, to facilitate connection.
It is additionally provided with locking nut 5 on the screw press 2, it is fixed for the screw press 2 after adjusting will to be rotated, it prevents from adjusting
Press the loosening of screw rod 2.The pressure regulation pressure indicating graduation plate 4 is connect by bolt with the sensor body 1.The pressure regulation pressure
The material of power indicating graduation plate 4 is high-intensitive organic glass, in order to observe quarter corresponding to the position after 3 pressure regulation of pressure spring
Degree.
When needing to adjust high-low pressure sensor settings pressure value, unscrew locking nut 5, it at this time can be to screw press 2
The adjusting of up/down pressure is carried out, the pressure spring 3 being attached thereto changes under the action of screw press 2 acts on sensor
Pressure value on ontology 1, in pressure regulation pressure indicating graduation plate 4, (scale value is to pass through essence when leaving the factory according to different springs at this time
Quasi- calculating, measurement obtain) on can accurately see that 3 corresponding pressure value of pressure spring, this pressure value are the setting of sensor
Pressure value after being then transferred to desired pressure set points, then locking nut 5 is locked, and be fixed can not pine for screw press 2 at this time
Dynamic, pressure setting is completed, it is no longer necessary to which removal sensor can accurately complete pressure adjusting；Pressure indicating graduation plate is by height
Intensity organic glass is made, possessed transparent, sealing, the entirely appropriate live use environment of high-strength characteristic.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read above content, for of the invention
A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
