Abstract
The invention relates to an automatic filling device of a liquid tank car. The automatic filling device comprises a filling pump, wherein the inlet of the filling pump is connected with a liquid storage groove through a pipeline, the outlet of the filling pump is connected with the liquid tank car through the pipeline, and a flowmeter is arranged at the outlet of the filling pump. The automatic filling device has the beneficial effects of simple structure and reasonable design, low temperature liquid discharged from the outlet of the filling pump is measured by the flowmeter online and can be accumulated automatically, so that the volume of the liquid flowing into the tank car can be controlled, and the liquid can be filled quantificationally according to different volumes of the tank cars; after filling, the filling pump is controlled remotely to stop running automatically, so that the problem of excessive filling is solved, and the safety of people and equipment is guaranteed.
Description
Technical field
The present invention relates to a kind of for preventing the liquid tank car automatic charging device of liquid tank car overfilling.
Background technique
In routine work, when liquid is filled, because the personnel of filling lack a sense of responsibility, estimate inaccurate or on-the-spot level meter, break down, cause the liquid tank car excessive even superpressure phenomenon often to occur filling, and then cause safety valve jumping up, staff and equipment are produced to serious potential safety hazard.
Summary of the invention
The object of the invention is to: the problem existed for above-mentioned prior art proposes liquid tank car automatic charging device a kind of simple in structure, reasonable in design.
In order to reach above purpose, liquid tank car automatic charging device of the present invention, its improvements are, comprise filling pump, the entrance of described filling pump is connected with liquid storage groove by pipeline, and outlet is connected with the liquid tank car by pipeline, in described filling pump outlet port, is provided with flowmeter.
It is that described sufficient pump is centrifugal filling pump that the present invention further improves.Described filling pump is connected with tele-control system, according to the volume of tank car, sets and fills time and filling weight in advance, and while while filling, reaching predetermined value, tele-control system can be controlled filling pump and shut down.
It is that described flow is counted cryogenic flow amount meter that the present invention further improves.Flowmeter is connected with tele-control system.
The invention has the advantages that: liquid tank car automatic charging device of the present invention is simple in structure; reasonable in design; the cryogenic liquide that the outlet of flowmeter on-line measurement filling pump is discharged; and can automatically add up; thereby control the liquid volume that enters tank car, so that quantitatively fill telecontrol filling pump autostop after having filled according to the not co-content of tank car; to avoid the overfilling problem, personnel and device security have been ensured.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
Embodiment
Embodiment one
The liquid tank car automatic charging device of the present embodiment, comprise filling pump 2, and the entrance of filling pump 2 is connected with liquid storage groove 1 by pipeline, and outlet is connected with liquid tank car 4 by pipeline, in filling pump 2 outlet ports, is provided with flowmeter 3.Filling pump 2 is low-temperature centrifugation formula filling pump, can be connected with tele-control system, according to the volume of tank car 4, sets and fills time and filling weight in advance, and while while filling, reaching predetermined value, tele-control system can be controlled filling pump 2 and shut down.Flowmeter 3 is the low temperature flowmeter.
During actual the use; set filling weight according to the volume of tank car on tele-control system; then starting 2 pairs of liquid tank cars 4 of filling pump is filled; flowmeter 3 real time measures integrated flow; when flux cumulating during to the filling weight set; tele-control system is given 2 one stoppage in transit signals of filling pump automatically, controls filling pump 2 and shuts down.Like this, can effectively avoid the liquid tank car excessive or even superpressure phenomenon to occur filling, for the safety of staff and equipment provides effective guarantee.
In addition to the implementation, the present invention also can have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, drop on the protection domain of requirement of the present invention.
