Description
Technical field
The utility model is applied to pressure gauge detection field, more particularly to a kind of for LNG cryogenic liquid gas storage tanks
The detection means of differential pressure levelmeter.
Background technology
In recent years, natural gas gradually expands, turned into as a kind of economic, green, the novel energy of environmental protection, its application field
The first choice of the social enviroment protection energy.To adapt to social demand, liquefied natural gas LNG storage equipment also fast development, there is well
Spray formula demand, there are a variety of LNG accumulatings dresses such as LNG horizontal low temperatures tank, LNG vertical low temperatures tank and polarstream, cryogenic tank case
It is standby.
On these LNG low temperature storage equipments, there is a differential pressure levelmeter, for show gas phase pipeline and liquid phase pipeline it
Between pressure differential, but in use, usually because differential pressure levelmeter reading is forbidden to bring puzzlement to user.In order to understand fully differential pressure
Whether liquid level gauge working condition is in shape, it is necessary to design a set of differential pressure levelmeter detection means, but maximum level produces
Pressure value only 0.01MPa, if display less than 0.01MPa pressure value, it is necessary to use precision as millesimal pressure-reducing valve
And pressure gauge, such precision instrument price costly, are also not suitable for being applied to the operating mode that field is often jolted.
The content of the invention
The utility model solve technical problem be：A kind of simple inspection for being easy to detect differential pressure levelmeter working condition is provided
Device is surveyed, the installation cost is low, easy to detect.
The utility model adopts the technical scheme that：
The gas phase pipe interface of differential pressure levelmeter and air are connected, liquid phase pipeline interface is connected with pressue device；Institute
Stating pressue device includes communicating pipe, U-tube manometer and glueballs capsule, the communicating pipe respectively with liquid phase pipeline interface, glueballs capsule and U
One end of U-tube manometer is tightly connected；The other end of the U-tube manometer communicates with air.
Further, pressure value is read for ease of quick, high-precision digital-display pressure gauge is connected with pressue device.
The utility model obtain technological progress be：The detection means is simply easily realized, cost is low, pressure is convenient and swift,
Measurement result is accurate；Using the device, the working condition of differential pressure levelmeter, the differential pressure that is particularly suitable for use in liquid level can be detected whenever and wherever possible
Meter stock up, the detection of factory state, and user to differential pressure levelmeter reading produce query when detection.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment 1；
Fig. 2 is the structural representation of the utility model embodiment 2；
Wherein：1-U U-tube manometers, 2- flexible pipes I, 3- threeways I, 4- pipelines, 5- threeways II, 6- liquid phase pipelines interface, 7- gas
Phase pipe interface, 8- differential pressure levelmeters, 9- glueballs capsule, 10- flexible pipes II, 11- high-precision digital-display pressure gauges.
Embodiment
Embodiment 1：
Fig. 1 is the structural representation of the present embodiment.The gas phase pipe interface 7 of differential pressure levelmeter 8 communicates with air, liquid-phase tube
Road interface 6 is connected by pipeline 4 with an interface of threeway I 3, and second interface of the threeway passes through flexible pipe I 2 and U-shaped pressure
One end connection of meter 1, the other end of U-tube manometer 1 are communicated with air, and the 3rd interface of the threeway is connected by flexible pipe II 10
Glueballs capsule 9.In all connections, being required to sealing must not gas leakage.
When detecting 8 working condition of differential pressure levelmeter using the device, water first is injected in U-tube manometer 1, controls U-shaped pressure
Water level in power meter 1 reaches middle 0 scale, and after water level is steady, hand is pinched glueballs capsule 9 and slowly pressurizeed, now pipeline 4, the and of flexible pipe I 2
It is same pressure in flexible pipe II 10, is pressurized to after certain pressure and stops pressurization, keep stable state, the water column difference in U-tube manometer 1 is
For the pressure of liquid phase pipeline interface 6, gas phase pipe interface 7 communicates with air, the pressure with logical air one end of U-tube manometer 1
Unanimously, so the pressure of water column difference is the pressure differential of differential pressure levelmeter 8.If the pressure show value of differential pressure levelmeter 8 and water
Post differential pressure is consistent or in its accuracy rating, then the working condition of differential pressure levelmeter 8 is good.
Embodiment 2：
Fig. 2 is the structural representation of the present embodiment.The present embodiment and the difference of embodiment 1 are：Added on pipeline 4
Threeway II 5, threeway connection high-precision digital-display pressure gauge 11, facilitates reading.
The device application method of embodiment 2 is same as Example 1, has simply used high-precision digital-display pressure gauge 11, reading
It is convenient and swift, while pressure comparison can also be carried out with the water column difference in U-tube manometer 1.
Structure of the detecting device of the present utility model is simple, cost is low, pressure is simple and convenient, it is easy to operate, it is easy realize, measurement knot
Fruit is accurate；Using the device, the working condition of differential pressure levelmeter can be detected whenever and wherever possible, and the differential pressure levelmeter that is particularly suitable for use in enters
The detection of goods, factory state, and user to differential pressure levelmeter reading produce query when detection.Facilitate LNG storage tank
User, the factory of LNG storage tank has been also convenient for it.
