Description

Technical Field

[0001] The utility model belongs to the technical field of sealing, and in particular relates to an environmentally friendly sealing device for a fuel oil crane pipe. Background Art

[0002] At present, the fuel oil loading crane pipe can only meet the interface requirements of tank truck loading with a diameter of Φ240-290mm and a neck height of 5-100mm. With the current social transportation vehicles, there are also tank trucks with other loading diameters. When the existing sealing form is used for other loading diameters, it is easy to cause the crane pipe to be poorly sealed, oil and gas to leak, and the oil and gas cannot be collected and transported to the platform oil and gas recovery device through the gas collecting pipe to pollute the environment. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing sealing structure cannot adapt to tank trucks of any loading caliber.

[0004] In order to solve the above technical problems, the specific technical solutions of the utility model are as follows:

[0005] A fuel oil crane pipe environmental protection sealing device, comprising a sealing ring 1, an upper fixing ring 2, a joint bolt 3, a zipper 4, a cloth-reinforced telescopic tube 5, a clamp 6 and a lower fixing ring 7;

[0006] The right end of the upper fixing ring 2 is fixed with a sealing ring 1, which is a wedge-shaped sealing ring; the two ends of the cloth-clamping telescopic tube 5 are respectively connected to the left end of the upper fixing ring 2 and the right end of the lower fixing ring 7 through a clamp 6; the two ends of the zipper 4 are respectively connected to the outer side of the upper fixing ring 2 and the outer side of the lower fixing ring 7;

[0007] The inclined surface of the wedge-shaped sealing ring is connected to the flange of the tank car loading port; the left end of the lower fixing ring 7 is fixed to the fuel oil crane pipe.

[0008] The utility model has the following advantages: it can adapt to vehicles of any loading caliber, avoid oil and gas leakage, fully recover oil and gas, and send them to the platform oil and gas recovery device, which not only achieves the purpose of environmental protection, but also protects the health of on-site supervisors and operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is a schematic structural diagram of the fuel oil crane pipe environmental protection sealing device of the utility model. DETAILED DESCRIPTION

[0010] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0011] like Figure 1As shown, the fuel oil crane pipe environmental protection sealing device of the utility model comprises a sealing ring 1, an upper fixing ring 2, a joint bolt 3, a zipper 4, a cloth-clamped telescopic tube 5, a clamp 6 and a lower fixing ring 7;

[0012] The right end of the upper fixing ring 2 is fixed with a sealing ring 1, which is a wedge-shaped sealing ring; the two ends of the cloth-clamping telescopic tube 5 are respectively connected to the left end of the upper fixing ring 2 and the right end of the lower fixing ring 7 through a clamp 6; the two ends of the zipper 4 are respectively connected to the outer side of the upper fixing ring 2 and the outer side of the lower fixing ring 7;

[0013] The inclined surface of the wedge-shaped sealing ring is connected to the flange of the tank car loading port; the left end of the lower fixing ring 7 is fixed to the fuel oil crane pipe.

[0014] The sealing form of this embodiment is a high temperature resistant wedge seal, which can withstand high temperatures to a limited extent, avoiding excessive oil temperature and seal aging. At the same time, the wedge design can adapt to tank trucks of any loading caliber. A gabu telescopic tube is set on the upper part of the seal, which has telescopic elasticity to avoid oil and gas leakage. At the same time, a zipper is set on the outside of the gabu telescopic tube, so that the gabu telescopic tube can play a fixed protection role when the gabu telescopic tube expands and contracts with the tank truck liquid level, preventing the extension amount from being too large, causing the gabu telescopic tube to be pulled by external force, and avoiding the possibility of tearing.

[0015] It can adapt to vehicles of any loading caliber, avoid oil and gas leakage, fully recover oil and gas, and send them to the platform oil and gas recovery device, which not only achieves the purpose of environmental protection, but also protects the health of on-site supervisors and operators.

[0016] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements should also be considered to belong to the protection scope of the present invention.
