Abstract
A dual-flowmeter multimode oil injection piping system is formed by an oil adding unit and a measurement unit in series, and is characterized in that the measurement unit is a dual-channel measurement branch with the parallel connection comprising a three-way ball valve QT2 at the measurement inlet, a 3-way ball valve QT3 at the measurement exit, and a main flowmeter A and a standby flowmeter B both of which arranged by the parallel connection between the 3-way ball valve QT2 at the measurement inlet and the 3-way ball valve QT3 at the measurement exit. The utility model can carry the measurement accurately and avoid the administrative defects of Opening Windows for the fuel oil provision.
Description
Technical field:
The utility model relates to fuel delivery systems, more specifically says so to be used to realize the fuel delivery systems of the standby granting of flowmeter.
Background technique:
Present simple in structure, the function singleness of using of railway fuel delivery systems, the hair oil mode of its single flowmeter has the blank phenomenon, promptly break down or flowmeter need examine and determine the time at the metering pipeline, because single table metering, in order not stop hair oil, the way that each filling-up area adopts is oil-feed place and the straight tube of fuel-displaced place bridge joint at the metering pipeline, when the metering pipeline quits work, straight tube by bridge joint directly carries out hair oil to locomotive, and this blank phenomenon is managerial one big leak.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology deficiency, a kind of pair of flowmeter multimode hair oil pipe-line system being provided, so that the administrative vulnerability of accurately metering, elimination fuel oil granting blank.
The technological scheme that the utility model technical solution problem is adopted is:
The utility model is made of the series connection of oil filling unit and batching unit, and its structural feature is that described batching unit is by metering inlet tee ball valve QT2, metering outlet tee ball valve QT3 and is arranged in parallel main flow meter A between metering inlet tee ball valve QT2 and metering outlet tee ball valve QT3 and two-way metering in parallel branch road that standby flowmeter B constitutes.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the two flowmeters of the utility model are arranged in parallel, and have greatly improved the functional reliability of system, have avoided the phenomenon that puts in a skylight.
2, the utility model adopts tee ball valve that two flows are selected, and overall structure is simple, and is few with valve, is easy to be provided with at the scene.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Number in the figure: QT1 filler opening tee ball valve, GL filter, mortor operated valve, Q1 two logical fuel inlet ball check valves, QT2 metering inlet tee ball valve, QT3 metering outlet tee ball valve, A main flow meter, the standby flowmeter of B.
Below pass through embodiment, and in conjunction with the accompanying drawings the utility model be further described:
Embodiment:
Referring to accompanying drawing, the present embodiment whole system is made of oil filling unit, batching unit and the series connection of temperature transducing unit.
Shown in the figure, oil filling unit is that two outlets by filler opening tee ball valve QT1 are arranged in parallel two oiling branch roads, article one, be the automatic oiling branch road that is made of filter GL, mortor operated valve DDF and two logical fuel inlet ball check valve Q1, another is the straight-through manual branch road of bridge joint between filler opening tee ball valve QT1 and two logical fuel inlet ball check valve Q1 outlets;
Batching unit is by metering inlet tee ball valve QT2, metering outlet tee ball valve QT3 and is arranged in parallel main flow meter A between metering inlet tee ball valve QT2 and metering outlet tee ball valve QT3 and two-way metering in parallel branch road that standby flowmeter B constitutes.
Three temperature transmitter T1, T2 that the temperature transducing unit is provided with for series connection and T3.
In the present embodiment, in the hair oil system, introduce mortor operated valve DDF,, match with mortor operated valve DDF and PLC and to realize control hair oil operation automatically to substitute original stop valve, and in this main mode as daily hair oil.Keep manual hair oil mode simultaneously, as emergency power.The switching of automated manner and manual mode realizes by filler opening tee ball valve QT1.
Adopt two flowmeters to be installed in parallel, in main flow A is flowmeter commonly used, with standby flowmeter B as standby flowmeter, by metering inlet tee ball valve QT2 and the different circulation status of metering outlet tee ball valve QT3, coming selected is single table metering or the metering of two table, and specifically selects for use which platform table to carry out flow measurement.
Three temperature transmitter T1, T2 and T3 deliver to PLC with real-time oily temperature and carry out density conversion accurately, thereby can realize accurate mass metrology; Three temperature transmitters use simultaneously, and the one, break down in order to prevent temperature transducer, be convenient to fault verification; The 2nd, the measured value of three temperature transmitters is put to the vote, can more accurate measurement temperature value, also can easier find the temperature transducer that breaks down, in time handle, guaranteed accuracy, the reliability of system's metering.
Specific constructive form in the present embodiment can realize multimode fuel oil simple and direct between providing and switch fast, comprise:
Realize providing automatically, simplify and provide operation;
The mode of a plurality of temperature transmitter thermometric values voting is for the accurate measurement of system provides reliable assurance.
Real-time oily temperature is delivered to PLC carry out density conversion accurately, thereby realize accurate mass metrology.
Concrete attainable hair oil mode is as follows:
