Abstract
The invention relates to a pressure checking device of a pressure sensor. The prior pressure sensor not only wastes the time but also influences the service life and the measuring accuracy of the device frequently by disassembling and assembling inner structure of the device frequently while checking due to the sensor is hermetically arranged within the mounting base of the device. The pressure checking device of a pressure sensor provided by the invention comprises an external pressure-proof pipe, wherein one end of the external pressure-proof pipe is equipped with a lower connector, the outer end of the lower connector is equipped with a checking plug, the outer end of the lower connector is further covered with a protection shell, and the protection shell is provided with a through hole which is communicated to the checking plug. The pressure checking device of a pressure sensor provided by the invention has the advantages that the work of precise pressure check can be carried out just by connecting the interface of the pressure checking platform to the checking plug without disassembling the inner structure of the device and changing the inner structure while checking, the time and the cost are saved and the accuracy of the device can be ensured effectively.
Description
Technical field
The present invention relates to a kind of pressure checking device, specifically refer to a kind of device that is used for verification pressure transducer pressure.
Background technology
The pressure transducer pressure checking link that in experimentation, is absolutely necessary, and existing pressure transducer since sensor package in the mount pad of instrument, sensor must be taken out during verification to be installed in just can be connected on the other cover loader mechanism and carry out the pressure checking test on the pressure calibration, make in experimentation the inner structure of wanting continuous dismounting instrument, not only lose time, usually influence instrument life-span and measurement accuracy.
Summary of the invention
The technical problem to be solved in the present invention provides the pressure checking device of pressure transducer, it is when verification, only the pressure calibration interface need be received and carry out verification above the sensor, need not to dismantle instrument and take out sensor, not only save time, and avoided trouble that dismounting brings and the precision that influences instrument.
For solving the problems of the technologies described above, the pressure checking device of a kind of pressure transducer of the present invention comprises withstand voltage outer tube, and withstand voltage outer tube one end is arranged with lower sub, it is characterized in that: the outer end of described lower sub is provided with a verification plug.
The outer end of above-mentioned lower sub is also outer to be with protecting sheathing, and protecting sheathing is provided with the through hole that communicates with the verification plug.
The present invention is with respect to existing calibration equipment; under the situation that need not change inner structure; by at lower sub outer setting protecting sheathing; make when verification; need not dismantle the inner structure of instrument, only need the pressure calibration interface received above the verification plug that improves structure and can carry out accurate pressure checking, and need not the design verification loader mechanism; not only save time and cost, also can effectively guarantee the precision of instrument.
Description of drawings
Fig. 1 is existing calibration equipment structural representation.
Fig. 2 is a structural representation of the present invention.
Among the figure, the withstand voltage outer tube of 1-, 2-pressure ring, 3-pad, 4-sensor mount pad, 5-pressure transducer, 6-lower sub, 7-verification plug, 8-protecting sheathing, 9-through hole.
Embodiment
Referring to Fig. 1, existing pressure transducer pressure checking device comprises withstand voltage outer tube 1, pressure ring 2, pad 3, sensor mount pad 4, pressure transducer 5 and lower sub 6, the sheathed lower sub 6 of one end of withstand voltage outer tube 1, setting is equipped with pressure transducer 5 and pad 3 successively in the lower sub 6, the sensor mount pad 4 of pressure ring 2, when carrying out verification, lower sub 6 and withstand voltage outer tube 1 must be taken apart, and pressure ring 2 and pad 3 are laid down, pressure transducer 5 taken out from sensor mount pad 4 and it is installed in and just can receive pressure calibration on the other cover verification loader mechanism and carry out the pressure checking test, verification finishes the back can carry out well logging work according to anti-workflow with its installation.
Referring to Fig. 2; pressure transducer pressure checking device of the present invention; under the situation that does not change inner structure; on the outer end of lower sub 6, be processed with opening; with 7 mounted thereto of verification plugs; and in order to prevent uncertain hazards in the checking procedure; be with protecting sheathing 8 outside on the outer end of lower sub 6, going back; offer the through hole 9 that communicates with verification plug 7 on the protecting sheathing 8; protecting sheathing 8 can guarantee the precision of pressure checking test; during verification; only need verification plug 7 be connected with pressure calibration and carry out verification by through hole 9; verification after finishing is unloaded protecting sheathing 8 down, the logical plug of an other screw thread is dismantled and changed to verification plug 7 just can log well work normally.
