The block of closure bar one end is stuck in one end of reducing pipe, the other end connection capping of reducing pipe；Or the other end connection of reducing pipe
The sleeve pipe that extension tube attached one end is set, the push rod one end at this moment set in extension tube attached, which is withstood in the blind hole that the closure bar other end is set, to be made
Block bar and depart from reducing pipe, obtain by the fluid path in tank body pipe end, reducing pipe to extension tube attached, the extension tube attached connecting valve
Or pipeline.
Described avoiding improper opening pipeline temporary closure, external screw thread is provided with the pipe end outer edge surface of tank body, blocks Guan Lian
The internal thread of adapter one end is threadedly coupled with the external screw thread of the pipe end, in the end of pipe end and the closure pipe connected pipe other end
Rubber blanket is provided between annular slab.
Described avoiding improper opening pipeline temporary closure, multiple projections are interval with the other end outer rim of push rod, it is described
Project through the inwall of solder joint connection extension tube attached.
Described avoiding improper opening pipeline temporary closure, the other end for blocking bar are arranged to conical head.
By adopting the above-described technical solution, the present invention has the advantages that：
Avoiding improper opening pipeline temporary closure of the present invention, it is adapted to liquid tank and liquid tank car to use, in liquid tank
Or before liquid tank car loads liquid using top, the first connecting tube by original replacing valve for the present invention, and make the envelope of block
Blocked shot blocks reducing pipe one end, and the other end of reducing pipe is then closed using capping and can take precautions against unrelated person to storage thing
Pick and place；When liquid tank when needed；Or liquid tank car transport is reached when providing landing place, by the way that capping is removed, Ran Houan
Tubing, penetrating the blind hole of closure bar when installing sleeve pipe by push rod makes block depart from annular slab, it is necessary to which explanation is extension tube attached
Valve or pipeline can be installed, to store the releasing of thing, by installing the storage of the invention that can make in liquid tank or liquid tank car
Storage is not removed, to ensure to store the safety storage of thing；The present invention is simple in construction, prevents liquid tank or liquid tank car from transporting
It is stolen in defeated way.

【Embodiment】
With reference to the following examples, the present invention can be explained in greater detail；It should however be noted that not office of the invention
It is limited to following embodiments；The open purpose of the present invention is intended to protect all changes and improvements in the scope of the invention.
Avoiding improper opening pipeline temporary closure with reference to described in accompanying drawing 1,2 or 3, including the pipe end 13 of tank body, closure pipe, gear
Block 4, capping 2, extension tube attached 8 and push rod 9；External screw thread, closure pipe connected pipe 16 one end are provided with the outer edge surface of pipe end 13 of tank body
Internal thread be threadedly coupled 15 with the external screw thread of the pipe end 13, in the end of pipe end 13 and closure pipe connected pipe 16 other end
Rubber blanket 17 is provided between annular slab 1, the other end internal orifice of connecting tube 16 is provided with annular slab 1, and the one end of reducing pipe 3 is arranged on annular slab
On 1 internal orifice, the internal orifice of described one end of reducing pipe 3, which is provided with outer edge surface, has the closure bar 19 of rubber ring 6, blocks the another of bar 19
One end is arranged to conical head 20, and the block 4 of described closure bar 19 one end is stuck in one end of reducing pipe 3, and the other end of reducing pipe 3 connects
Connect capping 2；Or it is provided with multiple raised 10, described raised 10 at the other end outer rim interval 18 of push rod 9 and is connected outside by solder joint 11
The inwall of adapter 8, the internal thread 12 of the inwall of sleeve pipe 7 setting of other end connection extension tube attached 8 one end setting of reducing pipe 3, at this moment
The one end of push rod 9 set in extension tube attached 8, which is withstood in the blind hole 5 that closure bar 19 other end is set, makes closure bar 19 depart from reducing pipe 3,
Obtain the neutral gear passed through by the liquid of tank body outflow between the inside pipe wall 14 of pipe end 13, the internal orifice of reducing pipe 3, the internal orifice of extension tube attached 8 and top
The valve or the liquid outflow pathway of pipeline set in interval 18 to extension tube attached 8 between the projection 10 and projection 10 of bar 9.
Implement avoiding improper opening pipeline temporary closure of the present invention, when being used in liquid tank and liquid tank car "
It is exactly before loading liquid in liquid tank and liquid tank car ", first original valve is removed, then by the closure bar 19 of block 4
It is put into reducing pipe 3, is formed using the rubber ring 6 for blocking the setting of the outer rim of bar 19 and reducing pipe 3 is sealed, made in the case of slack tank
