Description
Technical Field
The utility model belongs to the technical field of machinery and specifically relates to an annular multi-angle sealing device.
Background
The hydrochloric acid has wide industrial application, strong pungent smell and high corrosivity. The concentrated hydrochloric acid has extremely strong volatility, and hydrogen chloride gas can volatilize to form acid mist after the container is opened.
Chinese patent CN216614036U discloses a hydrochloric acid loading device, which comprises a conical sealing cover, wherein a sealing ring 12 (matched with the inlet of a tank car) is arranged on the conical sealing cover, and the design can realize the sealing of the loading port of the tank car by combining the conical sealing cover with the sealing ring, so as to avoid the problem of medium acid mist diffusion. Chinese patent CN104555877a discloses a hydrochloric acid loading boom crane pipe, which comprises a sealing cap made of hydrochloric acid resistant rubber, wherein the sealing cap is conical. The two devices adopt the mechanical connecting rod to realize butt joint of the conical sealing cover and the tank car loading opening, the most ideal state of the devices is that the mechanical connecting rod is vertically inserted into the tank car loading opening to seal the tank car loading opening, but actually, the mechanical rod group is often obliquely inserted into the tank car loading opening, so that the conical sealing cover and the tank car loading opening form a certain gap, and the sealing effect is influenced.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model provides an annular multi-angle sealing device can avoid the emergence of above-mentioned problem.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides an annular multi-angle sealing device, includes one and annotates the liquid pipe, it is equipped with hemisphere sealing cap on the liquid pipe to annotate, annotate the liquid pipe and run through hemisphere sealing cap, hemisphere sealing cap's sphere supports and leans on the tank car loading mouth.
Furthermore, an upper annular sealing cover is arranged above the hemispherical sealing cap, and the edge of the upper annular sealing cover extends downwards to the middle of the hemispherical sealing cap.
Further, go up annular sealed cowling and include the roof, be equipped with annular arc baffle on the roof.
Further, the edge of the annular arc-shaped baffle plate is bent towards the direction close to the hemispherical sealing cap.
Furthermore, a plurality of permanent magnets are arranged on the edge of the annular arc-shaped baffle.
The utility model has the advantages that: the utility model discloses utilize the sealed cap of hemisphere can realize that the multi-angle of tank car carload mouth is sealed, go up annular sealed cowling and can support and lean on the tank car carload mouth outer wall, realize the sealed of tank car carload mouth, further make both laminating together with the help of the design of permanent magnet.
Drawings
Fig. 1 is a schematic structural view of a first usage state of the present invention;
fig. 2 is a schematic structural view of a second usage state of the present invention;
fig. 3 is a schematic structural diagram of a second embodiment of the present invention;
in the figure: the device comprises a tank car loading port 1, a liquid injection pipe 2, a hemispherical sealing cap 3, an annular sealing cover 5, a permanent magnet 52, a top plate 501 and an annular arc baffle 502.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the disclosed embodiments are merely exemplary of the invention, and are not intended to limit the invention to the precise embodiments disclosed. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the scope of the invention.
As shown in fig. 1 to 3, an annular multi-angle sealing device is inserted into a tank car loading port 1 and comprises a liquid injection pipe 2, wherein a hemisphere sealing cap 3 is arranged on the liquid injection pipe, the liquid injection pipe penetrates through the hemisphere sealing cap, and the spherical surface of the hemisphere sealing cap is abutted against the tank car loading port.
Furthermore, an upper annular sealing cover 5 is arranged above the hemispherical sealing cap, and the edge of the upper annular sealing cover extends downwards to the middle of the hemispherical sealing cap.
In at least one embodiment, the upper annular containment dome comprises a top plate 501 with an annular arc baffle 502 disposed thereon.
Further, the edge of the annular arc-shaped baffle plate is bent towards the direction close to the hemispherical sealing cap.
Further, as shown in fig. 3, the edge of the annular arc-shaped baffle plate is provided with a plurality of permanent magnets 52. When the liquid injection pipe is inserted into the tank car loading opening 1, the permanent magnet is adsorbed on the outer wall of the tank car loading opening.
In the working mode, as shown in fig. 1, when the liquid injection pipe is vertically inserted into a loading port of a tank car, the hemispherical sealing cap can perfectly seal the loading port of the tank car, and the edge of the upper annular sealing cover abuts against the outer wall of the loading port of the tank car to realize secondary sealing; as shown in fig. 2, when the liquid injection pipe is obliquely inserted into the tank truck loading opening, the hemispherical sealing cap still abuts against the outer wall of the tank truck loading opening to realize sealing; when the annular arc-shaped baffle plate is provided with the permanent magnet, the annular arc-shaped baffle plate can be tightly attached to the outer wall of the tank car loading opening by means of the magnetic force of the permanent magnet.
In addition to the technical features described in the specification, the technology is known to those skilled in the art.
