Abstract
The utility model relates to a portable comprehensive on-line tester which solves the technical problems that an existing detecting device is inconvenient to transport and use, low in efficiency and high in detection cost. The portable comprehensive on-line tester comprises a micro-pressure transmitter, a precise pressure gauge, a methane on-line monitor, an oxygen content analyzer, a charger and a power supply battery. The charger is connected with the power supply battery. The power supply battery is connected with the micro-pressure transmitter, the precise pressure gauge, the methane on-line monitor and the oxygen content analyzer through switches. The micro-pressure transmitter, the methane on-line monitor and the oxygen content analyzer are respectively connected with a pin valve. The portable comprehensive on-line tester can be widely applied to the monitoring over a natural gas pipeline.
Description
Technical field
The utility model relates to a kind of detecting instrument, particularly relates to a kind of portable comprehensive on-line testing instrument.
Background technology
As everyone knows, in the time carrying out natural gas line emptying, replace, put into operation and touch the operations such as mouth, need monitor accurately the pressure of pipeline, methane and oxygen content, to guarantee the security of construction.Existing detection technique is to carry out intermittent analysis and detection in valve chamber pressure tapping place sampling, to guarantee the parameter under different process state in pipeline, need to wear so a large amount of instruments and instrument.In order to detect the pressure-fired in pipeline, when operation, testing staff need shift to an earlier date huge pressure-fired detection case is transported to scene, but most of operations are to carry out in the wild, environmental baseline is all poor, vehicle is difficult to arrive valve chamber and check point, so, often transport heavy detecting instrument and instrument by manpower, bring great inconvenience to tester.And detecting instrument, instrument are various, normally with a pile instrument and instrument, also need to staggeredly detect different parameters in the different time periods, many time, be that a people cannot carry out, all very unfavorable to staffing and execute-in-place, cost is also higher.
Summary of the invention
The utility model is exactly in order to solve the transportation of existing pick-up unit, uses inconveniently, and the technical matters that efficiency is low, testing cost is high, provides a kind of easy to use, efficiency is high, testing cost is low portable comprehensive on-line testing instrument.
The portable comprehensive on-line testing instrument that the utility model provides, comprise micro-pressure transmitter, precision pressure gauge, methane on-line monitoring instrument, oxygen conten analyser, charger and supplying cell, charger is connected with supplying cell, and supplying cell is connected by switch with micro-pressure transmitter, precision pressure gauge, methane on-line monitoring instrument and oxygen conten analyser; Micro-pressure transmitter, methane on-line monitoring instrument and oxygen conten analyser are connected with needle-valve.
Further preferred technical scheme is that supplying cell is accumulator.
The beneficial effects of the utility model are, volume is little, compact conformation, simple to operate, be easy to carry; Save manpower, save time, efficiency is high, and testing cost is low.
The further feature of the utility model, by the description of following embodiment, is clearly recorded.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Reference numeral explanation:
1. micro-pressure transmitter, 2. precision pressure gauge, 3. methane on-line monitoring instrument, 4. oxygen conten analyser, 5. supplying cell, 6. charger, 7. tested pipeline, 8. pilot flexible pipe, 9. needle-valve.
Embodiment
As shown in Figure 1, the utility model comprises micro-pressure transmitter 1, precision pressure gauge 2, methane on-line monitoring instrument 3 and oxygen conten analyser 4, and charger 6 connects supplying cell 5; Supplying cell 5 is connected to its power supply by switch with micro-pressure transmitter 1, precision pressure gauge 2, methane on-line monitoring instrument 3 and oxygen conten analyser 4.
Precision pressure gauge 2 is communicated with tested pipeline 7 by pilot flexible pipe 8, and micro-pressure transmitter 1 is communicated with tested pipeline 7 by needle-valve 9, and methane on-line monitoring instrument 3 is communicated with tested pipeline 7 by needle-valve 9, and oxygen conten analyser 4 is communicated with tested pipeline 7 by needle-valve 9.
External power source charges to supplying cell 5 by charger 6, the preferred accumulator of supplying cell 5.
When use, first the force value of tested pipeline 7 can pass through the pressure changing of precision pressure gauge 2 Monitoring and Controlling processes, then opens corresponding needle-valve 9 according to process requirements, can read in real time corresponding data.For example, need to monitor minute-pressure value time, open the needle-valve 9 of micro-pressure transmitter 1 correspondence, connect its power supply, the pressure-fired value in tested pipeline 7 just can be detected in real time; Need to detect methane content, only need open the needle-valve 9 of methane on-line monitoring instrument 3 correspondences, switch on power, just can continue to detect methane content; Need to detect time, only need open the needle-valve 9 of oxygen conten analyser 4 correspondences, switch on power, just can continue to detect oxygen level.This device does not need testing staff detecting mouthful the different instruments of alternately rotation to detect different parameters always, simple to operate, easy to use, is convenient to field and carries, and can well overcome some unfavorable factors in present operation detection.
The above only, to preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.Every in claim limited range of the present utility model, any modification of making, be equal to replacement, improvement etc., all should be within protection domain of the present utility model.
