Problems solved by technology
For example, the defect of the cone seal is that many tank car ports are not standard round, and there may be gaps in the contact surface with the cone seal, resulting in air leakage; the defect of the bladder seal is that the structure is complex, the operation is cumbersome, and an air source is required; the magnetic bladder seal The seal can only be applied to the grooved opening with flanging, the applicable surface is narrow, and most of them are hard-connected, which will also cause air leakage

Embodiment Construction
[0036] The invention provides a novel sealing device for sealing a crane tube for loading a vehicle, which includes: a sealing cover, a locking device, a booster and an operating rod.
[0037] The booster is connected to the sealing cover and the locking device;
[0038] The sealing cover is used for full contact with the tank car mouth of the oil tanker to achieve good sealing;
[0039] The locking device is used to lock the inner upper wall of the oil tanker, so that the sealing device is closely connected with the oil tanker;
[0040] The booster is used to provide sufficient pressing force for the sealing surface formed between the sealing cover and the tank opening of the tank truck.
[0041] The sealing cover is provided with an oil-resistant rubber pad, and the oil-resistant rubber pad is aligned along the edge of the opening of the tank car tank to form a sealing surface.
[0042] The locking device has a lock tongue. When the crane tube is guided into the interior o...

The invention provides a seal device for hermetically entrucking a loading arm. The device comprises a seal cover, a position lock device, an assistor and an operating rod. The seal device has the advantages that 1, the seal can be realized in the process of oiling without transforming an oil tank truck, so that the seal cost can be greatly reduced; 2, the seal device is wider in application range, so that most of vehicle types on the market can be met; and 3, the invention is better in seal effect compared with common seal methods on the market, i.e. the cone seal, the capsule type seal and the like.
Description
technical field [0001] The invention relates to a sealing device that can be used for sealing a crane tube for loading vehicles, in particular to a sealing device that can be used for sealing a swing arm type top loading crane tube for loading vehicles. Background technique [0002] At present, many tank trucks in oil storage depots and refineries are equipped with oil and gas recovery facilities, which greatly improves the problem of oil volatilization in the fuel delivery process, and has achieved good social and economic benefits. However, due to the design of tank trucks The lack of relevant regulations has led to the different sizes of the openings of the tank trucks, resulting in imprecise seals, resulting in oil and gas leakage during the process of fueling the tank trucks, which has brought great difficulties to the recovery and collection of oil and gas, which directly affects the recovery of oil and gas device utilization efficiency. [0003] At present, the commo...
