Abstract
The utility model relates to a liquid pipeline ice blocking preventing structure of a differential pressure level meter of an LNG storing and transporting device. A shell body of the LNG storing and transporting device is provided with a differential pressure level meter installation hole, a connector is fixed inside the differential pressure level meter installation hole in a sealing mode, a lower liquid inlet pipe is fixed inside a shaft hole of the connector in a sealing mode, a connecting pipe is fixed inside the upper end of the lower liquid inlet pipe in a sealing mode, a protection cover is fixed at the upper end of the connector, the lower liquid inlet pipe and the connecting pipe are covered by the protection cover, the protection cover plays a role in preventing impaction, and the wall of the protection cover is provided with liquid penetrating holes. The liquid pipeline ice blocking preventing structure is safe and reliable, and the differential pressure level meter can work normally during the period when the device operates.
Description
Technical field
The utility model belongs to LNG warehousing and transportation facilities technical field, particularly the anti-stagnant ice bridging of a kind of differential pressure levelmeter structure.
Background technology
Along with the application of LNG warehousing and transportation facilities, in LNG storage and transport process, often occur that differential pressure levelmeter liquid lower pipeline is blocked up by ice at present, cause the inaccurate phenomenon of liquid level gauge reading, to storage and transport process, bring very large potential safety hazard.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides the anti-stagnant ice bridging of a kind of LNG warehousing and transportation facilities differential pressure levelmeter liquid lower pipeline structure, and it is safe and reliable, guarantees that differential pressure levelmeter can work at equipment run duration.
The technical scheme in the invention for solving the technical problem is: on LNG warehousing and transportation facilities housing, have differential pressure levelmeter mounting hole, sealing fixture splice in differential pressure levelmeter mounting hole, in the axis hole of joint, seal fixedly bottom feed tube, pipe is sealedly and fixedly connected in the upper pipes of bottom feed tube, the upper end fixed blade guard of joint, protective cover covers described bottom feed tube and connecting pipe, plays protecting against shock effect, on the wall of protective cover, has liquid drain hole.
The utlity model has following advantages: the effect 1), to feed tube road, LNG warehousing and transportation facilities differential pressure levelmeter bottom spot heating, can effectively prevent that pipeline is because temperature is too low and icing.2), can effectively guarantee differential pressure levelmeter normal operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model partial sectional view.
Embodiment
As shown in Figure 1, on LNG warehousing and transportation facilities housing 6, there is differential pressure levelmeter mounting hole, sealing fixture splice 3 in differential pressure levelmeter mounting hole, in the axis hole of joint 3, seal fixedly bottom feed tube 5, in the upper pipes of bottom feed tube 5, be sealedly and fixedly connected and manage 2, the upper end fixed blade guard 1 of joint 3, protective cover 1 covers described bottom feed tube 5 and connecting pipe 2, play protecting against shock effect, on the wall of protective cover 1, have liquid drain hole 7.
Described bottom feed tube 5 is wound around copper wire 4, and copper wire 4 one end are on the feed tube of differential pressure levelmeter bottom, and the other end is connected with warehousing and transportation facilities shell 6.Copper wire 4 plays transferring heat to managing the effect of 5 spot heating under differential pressure levelmeter liquid, prevents that liquefied natural gas (LNG) from the betting contest pipeline that freezes occurring because temperature is too low in differential pressure levelmeter bottom feed tube 5.
