Background technology
The energy of rock gas as a kind of high-efficiency cleaning and the important source material of petro chemical industry, play more and more important effect in the development of national economy.In recent years, along with the continuous increase of liquefied natural gas (LNG) demand, transhipment and the use equipment of liquefied natural gas (LNG) are widely used.On land the equipment transported and use is carried out to liquefied natural gas (LNG) and mainly comprise the Mobile low-temperature liquid transporting equipment such as low temperature liquid transportation semi trailer, charging liquid at low-temperature car and cryogenic liquid pot type container.Mobile low-temperature liquid transporting equipment generally adopts differential-pressure-type liquid level meter as the indicating device of liquid level in tank at present, differential-pressure-type liquid level meter is the liquid level measuring medium in tank according to the differential static pressure of different liquid level medium, and therefore the stability of the force value at the upper and lower mouth of pipe place of liquid level meter directly affects the fluctuation situation of liquid level meter pointer.Due to Mobile low-temperature liquid transporting equipment, to unload in liquid process and transportation pot liquid fluctuation larger filling, make the place's pressure surge of the liquid level meter high-pressure side mouth of pipe frequent, thus cause liquid level meter indicating value to occur to fluctuate by a relatively large margin, cannot height of liquid level inside container be judged.Because the long term frequent of pressure fluctuates, easily cause differential-pressure-type liquid level meter inner elastomeric diaphragm generation fatigue deformation, thus damage liquid level meter.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of stable-pressure device of the differential-pressure-type liquid level meter for transportable pressure vessel, and by design gas phase, liquid phase shroud and adapter, structure is simple, the effect that can reach steady pressure.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of differential-pressure-type liquid level meter stable-pressure device for transportable pressure vessel, structure comprises the liquid pipe and gas phase pipeline that are separately fixed at pressure vessel high-pressure side pressure tappings and low pressure end pressure tappings, its key is: be provided with the liquid phase shroud fixing with pressure vessel at described liquid pipe place, the surrounding of liquid phase shroud arranges at least one intercommunicating pore, and the top of liquid phase shroud is also provided with the adapter be communicated with liquid phase shroud inside.
Further, the free end of adapter is fixed by fixed mount and pressure vessel.
Further, described liquid pipe is made up of at least one section of bend pipe and pressure tappings is positioned at the liquid Space of liquid phase shroud.
Further, be provided with the gas phase shroud fixing with pressure vessel at gas phase pipeline place, gas phase shroud is provided with at least one air hole.
Further, described gas phase shroud or liquid phase shroud are square or semisphere or taper.
Further, described air hole is opened in surrounding and/or the bottom of gas phase shroud.
The beneficial effects of the utility model are: the design of gas phase shroud can reduce the impact that in vessel delivery process, in the gaseous pressure short time, rapid fluctuation causes liquid level meter pointer; Liquid phase shroud has devised the adapter of linker effect, and when in container during liquid level fluctuation, the liquid fluctuation in pipe is very little, plays the effect of steady pressure.
Below in conjunction with accompanying drawing, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1 is liquid pipe, and 2 is pressure vessels, and 3 is liquid phase shrouds, and 4 is adapters, and 5 is fixed mounts, and 6 is intercommunicating pores, and 7 is gas phase pipelines, and 8 is gas phase shrouds, and 9 is air holes.
Embodiment
Referring to accompanying drawing, inventive concept of the present utility model is the stable-pressure device designing a kind of differential-pressure-type liquid level meter for transportable pressure vessel, structure comprises the liquid pipe 1 and gas phase pipeline 7 that are separately fixed at pressure vessel 2 high-pressure side pressure tappings and low pressure end pressure tappings, key is: be provided with the liquid phase shroud 3 fixing with pressure vessel 2 at described liquid pipe 1 place, the surrounding of liquid phase shroud 3 arranges at least one intercommunicating pore 6, and the top of liquid phase shroud 3 is also provided with the adapter 4 be communicated with liquid phase shroud 3 inside.The free end of adapter 4 is positioned at ullage, plays linker, and when in container, liquid level fluctuates widely, liquid in pipe fluctuation is very little, plays the effect of steady pressure.
Described liquid pipe 1 is made up of at least one section of bend pipe and pressure tappings is positioned at the liquid Space of liquid phase shroud 3.
Be provided with the gas phase shroud 8 fixing with pressure vessel 2 at gas phase pipeline 7 place, gas phase shroud 8 is provided with at least one air hole 9.
Described gas phase shroud 8 or liquid phase shroud 3 are square or semisphere or taper.The shroud of also can be end be end enclosure structure.
When the utility model is specifically implemented: referring to accompanying drawing, the liquid pipe 1 of differential pressure type level gauge is connected with low pressure end pressure tappings with the high-pressure side pressure tappings of pressure vessel 2 respectively with gas phase pipeline 7.High-pressure side pressure tappings in pressure vessel 2 is fixedly installed the liquid phase shroud 3 of liquid pipe 1, the surrounding of liquid phase shroud 3 locates layout 1 ~ 4 intercommunicating pore 6 on lower side, the fixing adapter 4 be communicated with the inside of liquid phase shroud 3 above liquid phase shroud 3, the free end of adapter 4 is fixed by fixed mount 5 and pressure vessel 2.Adapter 4 plays linker, and when in container, liquid level fluctuates widely, liquid in pipe fluctuation is very little, plays the effect of steady pressure.Gas phase shroud 8 is provided with at gas phase pipeline 7 place of pressure vessel 2 inside, the gas of liquid level meter gas phase mouth annex and the gas-phase space of container top are effectively kept apart by gas phase shroud 8, reduce the impact that in vessel delivery process, in the gaseous pressure short time, rapid fluctuation causes liquid level meter pointer.The surrounding of gas phase shroud 8 and/or bottom are provided with air hole 9, ensure being communicated with of gas and gas in container in gas phase shroud 8.
