Description

Technical Field

[0001] The utility model relates to a sealing device, in particular to a split oil and gas recovery sealing device. Background Art

[0002] When oil is transferred from a train to a tanker, oil and gas will evaporate. Collecting the evaporated oil and gas and converting it from gas to liquid through absorption, adsorption or condensation is called oil and gas recovery, so that it can be fully utilized. The existing train loading platform uses a fixed conical sealing cap for oil and gas recovery, and the loading crane has no up and down, left and right movement space, resulting in poor sealing effect, which will cause oil and gas leakage.

[0022] The following is combined with Figure 1 To Attachment Figure 4 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0023] A split oil and gas recovery sealing device comprises a frame 1 and a rubber body 2, wherein the frame 1 and the rubber body 2 are detachably connected. The frame 1 is used to connect with a crane pipe for oil and gas recovery on a train and is fixed on the oil receiving port of a train tank car.

[0024] The skeleton 1 has a recess 3 that can accommodate the rubber body 2. Specifically, the skeleton 1 is a thin-walled part made of aluminum material, and the outer surface of the skeleton 1 is covered with rubber. The recess 3 is truncated cone-shaped, and the large end of the recess 3 is called the top surface of the recess 3, and the small end of the recess 3 is called the bottom surface of the recess 3. The large end of the recess 3 is provided with a circle of flanges 6 parallel to the bottom surface of the recess 3. Two lock buckles 7 are symmetrically connected to the flange 6. The lock buckles 7 can be selected from the existing quick-release lock buckles on the market, and their purpose is to fix the skeleton 1 on the oil receiving port. A through first hole 9 is provided on the bottom surface of the skeleton 1, and 12 fourth holes 12 with a diameter of 9 mm are arranged in an array in the circumferential direction around the first hole 9. The fourth hole 12 is a screw hole, and its purpose is to be connected to the rubber body 2.

[0025] The rubber body 2 has an unfolded state and a folded state. Figure 1 and attached Figure 2 The rubber body 2 is shown in a folded state. The rubber body 2 can be folded into the recess 3 in a concentric circle along a first direction to achieve a change from an unfolded state to a folded state. The first direction mentioned above refers to the axial direction of the rubber body 2. When the rubber body 2 is in an unfolded state, a passage 8 for oil and gas flow will be formed, and the passage 8 is axially aligned with the first hole 9 and connected to the first hole 9. The rubber body 2 is in a truncated cone shape in the unfolded state, and a first connecting part 4 and a second connecting part 5 are respectively provided at both ends of the rubber body 2. The first connecting part 4 is used to connect with the upper cover, which is located at the large end of the rubber body 2 and has a built-in support frame. Sixteen second holes 10 with a diameter of 9 mm are arranged in a circumferential array on the first connecting part 4, and the second holes 10 are screw holes, through which the rubber body 2 is connected to the upper cover. The second connecting part 5 is used to connect with the skeleton 1, which is located at the small end of the rubber body 2 and has a built-in support frame. The second connecting part 5 is connected to the bottom surface of the skeleton 1. The support frame is annular in shape, and its purpose is to ensure the connection strength between the first connection part 4 and the second connection part 5. Twelve third holes 11 with a diameter of 9 mm are arranged in a circumferential array on the second connection part 5. The twelve third holes 11 are axially aligned with the twelve fourth holes 12 one by one, and the skeleton 1 and the rubber body 2 are connected together by screws.

[0026] The utility model can improve the adaptability of the whole device by making the frame 1 and the rubber body 2 into a split type, so that the device can adapt to filling platforms of different models.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
