Description
Technical field
The utility model is applied to pressure gauge detection field, more particularly to a kind of differential pressure for cryogenic liquid gas storage tank
The detection device of liquid level gauge.
Background technology
In recent years, natural gas LNG gradually expands as a kind of economic, green, the novel energy of environmental protection, its application field,
As the first choice of the social enviroment protection energy.To adapt to social demand, the storage equipment of liquefied natural gas LNG is also grown rapidly, and is occurred
Blowout demand, there is a variety of LNG storages such as LNG horizontal low temperatures tanks, LNG vertical low temperatures tank and polarstream, cryogenic tank case
Fortune equipment.
On these LNG low temperature storage equipments, there is a differential pressure levelmeter, show between gas phase pipeline and liquid phase pipeline
Pressure differential, but in use, usually because differential pressure levelmeter reading is not allowed to bring puzzlement to user, in order to understand fully differential pressure liquid level
Whether meter working status is in shape, it is necessary to design a set of differential pressure levelmeter detection device, but the pressure that maximum level produces
Force value only 0.01MPa, if pressure value of the display less than 0.01MPa is, it is necessary to use precision as millesimal pressure reducing valve and pressure
Power table, 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 easy to detection differential pressure levelmeter working status is provided
Device is surveyed, the installation cost is low, easy to detect.
The technical scheme adopted by the utility model is that：
A set of identical pressue device is respectively connected on the gas phase pipe interface and liquid phase pipeline interface of differential pressure levelmeter, should
Pressue device includes communicating pipe, U-tube manometer, pressurization interface and valve, and described communicating pipe one end connects differential pressure levelmeter interface,
The other end connects one end of U-tube manometer, and the other end of U-tube manometer is communicated with air, is provided with and adds on the communicating pipe
Mouth is crimped, valve is installed on pressurization interface.The total interface of communicating pipe is tightly connected.In use, to two sets of pressurization dresses
Put and apply different pressure, the pressure differential of differential pressure levelmeter can be calculated from two U-tube manometers, compares differential pressure levelmeter
Reading may determine that the working status of differential pressure levelmeter.
The utility model obtain technological progress be：The detection device is simply easily realized, cost is low, measurement result is accurate；
Using the device, the working status of differential pressure levelmeter can be detected whenever and wherever possible, is particularly suitable for stocking up, dispatching from the factory for differential pressure levelmeter
The detection of state, and user to differential pressure levelmeter reading produce query when detection.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Wherein：1-U U-tube manometers I, 2- valve Is, 3- pressurizations interface I, 4- gas phases pipe interface, 5- differential pressure levelmeters, 6-
Liquid phase pipeline interface, 7- pressurizations interface II, 8- valves II, 9-U U-tube manometers II.
Embodiment
Fig. 1 is the structure diagram of the present embodiment.The gas phase pipe interface 4 and liquid phase pipeline interface 6 of differential pressure levelmeter 5 divide
Not Lian Jie a pressue device, the two pressue device structures are identical.The pressue device includes communicating pipe, U-tube manometer, pressurization
Interface and valve, described communicating pipe one end connect 5 interface of differential pressure levelmeter, other end connection U-tube manometer one end, U-shaped pressure
The other end of meter is communicated with air, and pressurization interface is provided with communicating pipe, and valve is provided with pressurization interface.With gas phase pipe
What road interface 4 connected is U-tube manometer I 1, pressurization interface I 3 and valve I 2 respectively, and what is be connected with liquid phase pipeline interface 6 is respectively
U-tube manometer II 9, pressurization interface II 7 and valve II 8.The total interface of communicating pipe is tightly connected.
When detecting differential pressure levelmeter 5 using the device, valve I 2 and valve II 8 are opened, in U-tube manometer I 1 and U-shaped pressure
Water is injected in power meter II 9, controls the water level in U-tube manometer I 1 and U-tube manometer II 9 to reach middle 0 scale.Water level is steady
Afterwards, the pressue device first to side pressurizes, for example, first the pressue device to connection gas phase pipe interface 4 adds from pressurization interface I 3
Pressure, can use glueballs capsule to pressurize, and also can use manually to blow and pressurize, then close valve I 2 rapidly, connect since communicating pipe is all
Mouth seals, the pressure holding stable state in communicating pipe, and the water column difference in U-tube manometer I 1 is the pressure of gas phase pipe interface 4.
Pressurizeed using pressue device of the same manner to 6 side of liquid phase pipeline interface, but the difference of two pressure need to be controlled.U-tube manometer I
The pressure differential that it is differential pressure levelmeter 5 that the difference of water column difference in 1 and the water column difference in U-tube manometer II 9, which is,.If differential pressure liquid
Position 5 pressure show values of meter are consistent with the pressure difference value of two water column differences or in its accuracy rating, then the work of differential pressure levelmeter 5 shape
State is good.
After having detected, open valve and diffuse pressure, be ready for the detection of next differential pressure levelmeter.
The detection device principle is simple, is easily achieved, and the simple cost of device is low, measurement result is accurate；, can using the device
The working status of differential pressure levelmeter is detected whenever and wherever possible, is particularly suitable for the stocking up of differential pressure levelmeter, the detection of factory state, with
And user to differential pressure levelmeter reading produce query when detection.
