TECHNICAL FIELD

[0001] The utility model relates to a sealing ring, especially a sealing ring for crude oil filling. BACKGROUND

[0002] When loading and unloading crude oil, the oil tank truck will appropriately recover oil gas. The recovered oil gas is converted from gaseous state to liquid state through a series of processes to achieve the purpose of recycling. In order to avoid the escape of oil gas into the atmosphere during the recovery process, a sealing structure needs to be used. The existing cone-shaped sealing cap is connected with the tank truck, but due to the pure rigid connection of the cone-shaped sealing cap, when the liquid surface is disturbed, the sealing will not be tight, causing oil gas leakage.

[0003] Therefore, the Chinese utility model patent with publication number CN219217565U discloses a telescopic sealing device for train loading oil gas recovery, which changes the original pure rigid sealing to pure flexible sealing, avoiding the situation of not strict sealing due to liquid surface disturbance. However, pure flexible sealing does not have any support in the axial direction, which makes the form of pure flexible sealing change greatly and is not stable enough. SUMMARY

[0004] In order to overcome the deficiencies in the prior art, the utility model provides a sealing ring for crude oil filling to provide sufficient axial support.

[0005] To achieve the above-mentioned purpose, the utility model discloses a sealing ring for crude oil filling, which comprises:

[0009] Preferably, the support rod comprises a rod body and a bracket, and the both ends of the rod body are respectively connected with one end of the bracket to form a spherical hinge, and the other end of the bracket is connected to the keel.

[0010] Preferably, the rod body comprises a first sub-rod, a second sub-rod and a spring, one end of the first sub-rod extends into the second sub-rod, the spring is arranged in the second sub-rod, and the both ends of the spring are respectively in contact with the first sub-rod and the second sub-rod. Under the action of the spring, the second sub-rod has a tendency to slide out of the first sub-rod.

[0011] Preferably, the keel is provided with fixing holes towards the outer side of the sealing body, the fixing holes are arranged in a circumferential array of the sealing body, and one end of the support is screwed into the fixing hole.

[0012] Preferably, the second sub-rod comprises a body and a sliding block, the sliding block is screwed into the body, and one end of the spring is in abutting connection with the sliding block.

[0013] Preferably, vulcanization holes are arranged in a circumferential array of the keel, and the sealing body is filled into the vulcanization holes when vulcanization is performed.

[0014] Preferably, the bottom of the sealing body is provided with a material hole in communication with the opponent.

[0015] Preferably, the top of the sealing body is provided with a skirt.

[0016] The utility model has the following technical effects:

[0017] 1. The support rod is connected between the keels of any two layers, and can provide sufficient axial support force for the sealing body to meet the use requirement.

[0018] 2.

DETAILED DESCRIPTION

[0026] The principles and characteristics of the present application are described below in conjunction with the embodiments; the examples are only used to explain the present application; and are not used to limit the scope of the present application.

[0027] A sealing ring for crude oil filling, comprising a sealing body 1, a keel 3 and a support rod 4. The sealing body 1 is in the shape of a cone cylinder, wherein the bottom of the sealing body 1 is provided with a through material hole 14, and the top of the sealing body 1 is provided with a skirt 15, and the bottom of the sealing body 1 and the skirt 15 are connected with the counterpart. The keel 3 is vulcanized and fixed with the sealing body 1, in order to ensure the stability of the connection between the sealing body 1 and the keel 3, the keel 3 is provided with a through vulcanization hole 13 along the circumferential direction, the sealing body 1 is made of rubber, and when the sealing body 1 is vulcanized and fixed with the keel 3, the rubber is filled into the vulcanization hole 13 to ensure the absolute fixation of the sealing body 1 and the keel 3. The keel 3 is at least one, when a plurality of keels 3 are provided, the plurality of keels 3 are arranged along the axial direction of the sealing body 1, and each keel 3 divides the sealing body 1 into two side sealing parts 2. Based on this, the sealing ring can exhibit two structures as shown in the accompanying drawings. Figure 1 and accompanying Figure 2 Two structures. The two ends of the support rod 4 are connected between any two layers of keels 3, whether it is adjacent to two layers or two layers apart can be determined according to the use requirements. The support rod 4 can provide sufficient axial support force for the sealing body 1.

[0028] In a preferred embodiment, the support rod 4 comprises a rod body 5 and a bracket 6, the two ends of the rod body 5 are respectively formed into a spherical hinge with one end of the bracket 6, and the other end of the bracket 6 is connected to the keel 3. In this structure, the support rod 4 not only can provide sufficient axial support force for the sealing body 1, but also can meet the circumferential torsion of the sealing body 1 within a certain range. The rod body 5 is a spring rod, specifically, the rod body 5 comprises a first sub-rod 7, a second sub-rod 8 and a spring 9, one end of the first sub-rod 7 extends into the second sub-rod 8, the spring 9 is arranged in the second sub-rod 8, and the two ends of the spring 9 are respectively in contact with the first sub-rod 7 and the second sub-rod 8. Under the action of the spring 9, the second sub-rod 8 has a tendency to slide out of the first sub-rod 7. When the sealing body 1 is twisted in the circumferential direction, the rod body 5 is in an inclined state, and its overall length will also change accordingly under the action of the spring 9. At the same time, in order to adjust the spring force of the spring 9, the second sub-rod 8 comprises a body 11 and a sliding block 12, the sliding block 12 is screwed into the body 11, one end of the spring 9 is in contact with the sliding block 12, moving the sliding block 12 outward can increase the spring force of the spring 9; moving the sliding block 12 inward can reduce the spring force of the spring 9.
