Description

Technical Field

[0001] The invention belongs to the technical field of deep-cold liquid filling, and in particular relates to a convenient plugging device with a horn head for liquid filling. Background Art

[0002] The cryogenic liquid produced by the air separation system or purchased cryogenic liquid needs to be connected to the storage tank through a metal hose, and most of its connectors are clevis interfaces.

[0003] In the air separation system, liquid oxygen is one of the main risk factors. During the transportation of liquid oxygen, it is strictly forbidden for impurities or oil to enter the pipeline. The important horn interface is in an open state when not in use, which poses a safety risk. If it is wrapped with other items, it is difficult to find flame retardants. If the pipe mouth is plugged with a traditional plug, it is likely to fall off under the action of external force. In order to solve the above problems, a liquid-filled horn convenient sealing device is provided.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a liquid-filled horn head convenient sealing device. By setting a retractable fixing plate, the sealing device can be fixed in the opening of the two U-shaped claws to prevent the sealing device from falling off. By setting a control component, the movement of the plug component can be controlled. At the same time, the conical plug body is set to a cone, so that the sealing device can be suitable for any model of horn head.

[0006] To achieve the above-mentioned purpose, the present invention proposes a liquid-filled convenient sealing device for a horn head, which is used to seal the horn head. The horn head includes an interface tube, one end of which is fixed with symmetrically distributed U-shaped claws, and the openings of the two U-shaped claws correspond to each other. The sealing device includes a sealing assembly, and the sealing assembly includes a retractable fixed plate, on which a plug assembly is slidably provided, and on which a control assembly for controlling the sliding of the plug assembly is rotatably provided.

[0007] The fixing plate includes a first connecting plate, and the plug assembly includes a first sliding rod perpendicular to the first connecting plate. A limiting block is fixed at one end of the first sliding rod, and a conical plug body is fixed at the other end passing through the first connecting plate. A second spring is fixedly connected between the plug body and the first connecting plate.

[0008] Furthermore, the control component includes a screw rod parallel to the first sliding rod, one end of the screw rod is fixed with a driving button, the other end passes through the first connecting plate and is rotatably provided with a third connecting block, the screw rod and the first connecting plate are threadedly matched, and a limiting strip is fixed on one side of the third connecting block.

[0009] A first limiting plate is vertically fixed to the large end of the plug body, and a second limiting plate is vertically fixed to the first limiting plate.

[0010] Furthermore, a third limiting plate is vertically fixed to the large end of the plug body, the third limiting plate corresponds to the through hole, and a fourth limiting plate distributed in an array is vertically fixed to one side of the third limiting plate.

[0011] Furthermore, a second connecting plate is slidably provided at both ends of the first connecting plate, a ladder-shaped bayonet is provided at one end of the second connecting plate away from the first connecting plate, a symmetrically distributed first connecting block is fixed below the first connecting plate, a second connecting block is fixed below the second connecting plate, the second connecting blocks correspond one-to-one to the first connecting blocks, and a first spring is fixedly connected between the second connecting block and the corresponding first connecting block.

[0012] Furthermore, a handle is fixed to one side of the second connecting plate.

[0013] Furthermore, a through hole is formed on the first connecting plate, and the third limiting plate corresponds to the through hole.

[0014] Furthermore, the second limiting plate and the fourth limiting plate are respectively located on two sides of the third connecting block.

[0015] The liquid-filled horn head convenient plugging device proposed by the present invention can bring the following beneficial effects:

[0016] 1. The plugging device of the present invention can be fixed in the openings of the two U-shaped claws by providing a retractable fixing plate to prevent the plugging device from falling off. The movement of the plug assembly can be controlled by providing a control assembly. At the same time, the conical plug body is set to a conical shape, so that the plugging device can be applied to any type of horn head;

[0017] 2. The sealing device of the present invention can adjust the distance between the first connecting plate and the plug body by inserting the limit strip between the plug body and the second limit plate, so as to facilitate the installation of the sealing device; by moving the limit strip out from between the plug body and the second limit plate, the plug body can be inserted into the interface tube under the action of the second spring, and the two second connecting plates respectively abut against the upper sides of the openings of the two U-shaped claws; by rotating the limit strip between two adjacent fourth limit plates, the plug body can be controlled to move into the interface tube to seal the pipe opening of the interface tube. Compared with directly adjusting the position of the plug body by bolts, this method can reduce the number of turns of the bolts and can achieve rapid installation of the sealing device.
