Abstract
The utility model relates to a double-probe sensor for a crude oil water ratio tester. A single-probe sensor composed of a shield, a front probe and a front core thread is additionally provided with a back probe, a back core thread and a sealing device to form a dual-probe sensor with a sealing device. When the utility model works, a short wave signal of 3.579 MHz is emitted to crude oil by the back probe, and the state of the present crude oil is checked; after a few seconds, the short wave signal of 3.579 MHz is emitted to the crude oil by the front probe and a signal of water in the oil is taken out, and then the difference of two measurement is obtained, so the instantaneous water ratio can be displayed after the amplification, the treatment and the calculation. The utility model has the advantages of true and accurate taken signal and good sealing effect.
Description
The utility model belongs to testing tool, is a kind of sensor of measuring crude oil water content.
At present, the sensor of the monitoring crude oil water content that domestic petrochemical industry is used is the shortwave absorption process, is single sonde-type, is promptly launched the short-wave signal of a 3.579MHZ to probe by heart yearn by the primary instrument circuit.Cause is single probe, flow velocity, pressure, temperature, density situation to monitoring water signal crude oil simultaneously can't detect, can only be above-mentioned situation people for being set to perfect condition, but growth along with monitoring time, promptly produce zero drift, so cause very big, stability of monitoring error and reliability not to reach customer requirements.Sensor directly contacts with crude oil simultaneously, and because of crude oil temperature is very high, pressure is very big, the medium that contains a lot of severe corrosives again, cause the hermetically-sealed construction between sensor probe and heart yearn pillar to lose efficacy, and cause sensor to move, the reliability that sensor is used reduces.
The purpose of this utility model is will provide a kind of can overcome zero drift, and it is accurate to measure numerical value, and the crude oil water content analyzer sensor of dependable performance.
Solution of the present utility model is at guard shield, preceding probe, increase the back probe on single probe sensor that preceding heart yearn is formed, back heart yearn and packoff, be formed with two probe sensors of packoff, wherein the back probe is tubulose, rear portion at preceding probe, the rear portion of preceding probe is a convex garden platform, on screw thread is arranged, the back anterior inner chamber of probe has fin, between preceding probe and the back probe refractory seals ring and oil resistant sealing ring are arranged, nut is equipped with at the screw thread place of preceding probe garden platform, the afterbody of back probe has the sealing adaptor body, the sealing adaptor body has internal thread and external thread, internal thread is connected with the external thread of back probe afterbody, be with the outer cover fittings body on the sealing adaptor body, the outer cover fittings body has internal thread and preceding external thread and back external thread, the external thread of sealing adaptor body connects outer cover fittings body internal thread, external thread connects guard shield afterbody internal thread before the outer cover fittings body, the outer cover fittings body connects the heart yearn pillar, the heart yearn pillar has internal thread to be connected with the back external thread of outer cover fittings body, wherein the sealing adaptor body is an insulating material, can be the teflon engineering plastics, the outer cover fittings body is a metallic conductor, heart yearn before preceding probe connects, and the back probe connects the back heart yearn, the afterbody of heart yearn pillar is equipped with the sealed insulation plate, tester is equipped with at sealed insulation plate place, and preceding heart yearn does not contact mutually with the back heart yearn, connects tester by the sealed insulation plate.During work guard shield is partly put into crude oil, at first in crude oil, launch the short-wave signal of 3.579MHZ by the back probe, current crude state is examined clearly, both made circuit part produce drift, but the absorption sample curve of measuring is actual, at interval after several seconds, in oil, launch the short-wave signal of 3.579MHZ by preceding probe, take out the signal of Water in oil again, get the difference that records for twice then, after processing and amplifying, reach computing and can demonstrate instantaneous water percentage.
The utility model adopts moisture signal in two probe monitoring crude oil, take out the signal true and accurate, overcome zero drift, resolution to Water in oil improves greatly, and the close structure of its envelope can guarantee that sensor is non-leakage under the situation of high temperature, high pressure, severe corrosive, the serviceable life of having improved instrument.
Further specify this reality is novel below in conjunction with drawings and Examples:
Fig. 1 is the utility model cut-open view;
Fig. 2 is the utility model partial sectional view.
The utility model guard shield 1, preceding probe 2, preceding heart yearn 3 is formed, there is convex garden platform 13 at the rear portion of preceding probe 2, platform 13 places in garden are with the back probe 4 of tubulose, the inner chamber of back probe 4 has fin 11, on the garden platform 13 screw thread is arranged, last cover nut 12, between preceding probe 2 and the back probe 4 refractory seals ring 9 and oil resistant sealing ring 10 are arranged, back probe 4 is in guard shield 1, the afterbody of back probe 4 is connected with sealing adaptor body 7, sealing adaptor body 7 has internal thread and external thread, back probe 4 afterbodys have external thread, be with outer cover fittings body 8 on the sealing adaptor body 7, outer cover fittings body 8 has internal thread and preceding external thread and back external thread, guard shield 1 afterbody has internal thread, outer cover fittings body 8 is connected with heart yearn pillar 6, heart yearn pillar 6 front ends have internal thread, back probe 4 and sealing adaptor body 7, sealing adaptor body 7 and outer cover fittings body 8, outer cover fittings body 8 is with guard shield 1 and heart yearn pillar 6 and is threaded, heart yearn 3 before preceding probe 2 connects, back probe 4 connects back heart yearn 5, heart yearn pillar 6 afterbodys are equipped with sealed insulation plate 14, and tester 15 is equipped with at sealed insulation plate 14 places, and preceding heart yearn 3 is connected tester 15 by sealing through listrium 14 with back heart yearn 5.
