Description

A kind of height pressure sensor with pressure indicating structure
Technical field
The utility model relates to high-low pressure sensor technical fields, and in particular to a kind of high-low pressure with pressure indicating structure Sensor.
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.
Utility model content
The purpose of the utility model is to provide a kind of height pressure sensor with pressure indicating structure, no longer to need to dismantle Sensor can accurately complete pressure adjusting.
A kind of in order to achieve the above object, the utility model provides height pressure sensor with pressure indicating structure, packet It includes: sensor body and screw press;The threaded hole with screw press cooperation is provided in the sensor body;It is described Pressure spring is provided in threaded hole;One end of the pressure spring is abutted against with sensor body, the other end and the pressure regulation Screw rod abuts against;Through-hole is provided in the sensor body of the pressure spring side;Pressure regulation pressure is provided on the through-hole to refer to Show scale 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 utility model has the following beneficial effects:
The utility model has structure simple, easy to operate;Operation, maintenance cost are low, and failure rate is low;Numerical value is accurate, property The very high feature of valence.The pressure setting of height pressure sensor provided by the utility model is mainly by adjusting its inside pressure regulation Spring reaches the adjustment of setting value, according to the characteristic of spring pressure or pulling force, sensor body outer surface aperture and increase It can show that the pressure regulation pressure indicating graduation plate of pressure can reflect the setting value of pressure of height pressure sensor, so that scene adjustment The operation of pressure value becomes convenient, simple, and pressure scale is tested repeatedly by factory can reach very exact value.This reality With it is novel can be in the case where not dismantling height pressure sensor, so that it may accurately complete pressure adjust.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of height pressure sensor of the utility model with pressure indicating structure.
Specific embodiment
Below in conjunction with attached drawing, by specific embodiment, the utility model will be further described, these embodiments are only used for Illustrate the utility model, is not the limitation to scope of protection of the utility model.
As shown in Figure 1, the utility model provides a kind of height pressure sensor with pressure indicating structure comprising: it passes Sensor ontology 1 and screw press 2;The threaded hole with the screw press 2 cooperation is provided in the sensor body 1;It is described Pressure spring 3 is provided in threaded hole;One end of the pressure spring 3 is abutted against with sensor body 1, the other end and the tune Pressure screw rod 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 Power indicating graduation plate 4, can the scale according to corresponding to the position after 3 deformation of pressure spring read adjust after pressure setting Value.Pipeline pressure tappings 6 are provided in the sensor body 1, for connecting the pipeline of pressure to be measured.The pipeline pressure tappings 6 are set It is equipped with external 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 content of the utility model has passed through above preferred embodiment, but it should be appreciated that on The description stated is not considered as limitations of the present invention.After those skilled in the art have read above content, for A variety of modifications and substitutions of the utility model all will be apparent.Therefore, the protection scope of the utility model should be by appended Claim limit.
