Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline sealing structures, and in particular relates to a sealing component and a ball collecting tube sealing structure. Background Art

[0002] The ball collecting cylinder is an important equipment for cleaning the long-distance pipelines in oil and gas fields. It is responsible for sending and receiving the pipe cleaner. It is a high-pressure equipment. The media in it are often toxic, harmful, flammable and explosive. Among them, the pipe cleaner is also called a pipe cleaning ball sending and receiving device, such as a simple pipe cleaning ball sending and receiving device disclosed in the patent document with patent number CN202110307115.5. The ball collecting cylinder is equivalent to the ball collecting cylinder body in the device, and an end cover plate is provided at its end. The end cover plate is connected to the ball collecting cylinder through a hinged connection structure and can be easily opened, so it is also called a quick-opening blind plate.

[0003] Since the seal of the original ball collecting tube is an imported seal, which is a sealing ring and is installed on the quick-opening blind plate, but is restricted by foreign technology, it is necessary to develop a different and effectively alternative sealing component to ensure the safety of equipment and personnel during the pipe cleaning operation. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a sealing component and a ball collecting tube sealing structure to replace the existing sealing ring between the pipeline and the end cover plate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] On the one hand, a sealing component is provided, which is used for sealing between a pipeline and an end cover plate, including an annular seal, the inner side of the seal having two sealing wings distributed along the circumferential direction, and an embedding groove for embedding the matching part of the end cover plate is formed between the two sealing wings, and the embedding groove is adapted to the matching part of the end cover plate.

[0007] In a possible implementation, the seal further has an annular body, and the two sealing wings are located inside the annular body and are spaced apart along the axial direction on the inside of the seal;

[0008] An annular elastic member is arranged inside the annular main body, and the elastic member is integrated with the sealing member.

[0009] In a possible implementation, the elastic member is a spring that is bent into a ring shape and embedded in the ring body, and the spring is adapted to the ring body.

[0010] In a possible implementation, the spring is located at the inner front side of the annular body to be close to the end cover plate.

[0011] In a possible implementation, an air hole penetrating toward the front and back sides of the sealing member is provided in the embedding groove.

[0012] In a possible implementation, the sealing element is made of rubber or silicone.

[0013] In a possible implementation, the two sealing wings are respectively a sealing front wing and a sealing rear wing, and the sealing rear wing is close to the back side of the end cover plate;

[0014] The front sealing wing extends obliquely toward the front side of the sealing element, and the rear sealing wing also extends obliquely toward the front side of the sealing element, and the front sealing wing and the rear sealing wing are parallel.

[0015] In a possible implementation, the side surfaces of the sealing front wing and the sealing rear wing located on one side of the embedding groove are both smooth curved surfaces;

[0016] The inner surface of the embedding groove is a smooth curved surface and smoothly transitions with the smooth curved surfaces of the sealing front wing and the sealing rear wing.

[0017] On the other hand, a ball receiving cylinder sealing structure is also provided, comprising a ball receiving cylinder, an end cover plate and a sealing component as described in any of the above technical solutions;

[0018] The end cover plate is hinged to one end of the ball collecting cylinder through a hinge; the sealing component is installed on the matching part of the end cover plate, and the sealing component seals the end cover plate and the ball collecting cylinder.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The sealing component of the utility model is suitable for sealing between a pipeline and an end cover plate. The embedding groove formed by the two sealing wings can be easily installed on the end cover plate, so that it has excellent wrapping and sealing properties. The two sealing wings have a certain length and can fit well on the end cover plate. When there is pressure on the equipment pipeline, the pressure will become tighter and tighter. The pressure can make the seal more tightly press the embedding groove of the end cover plate, further improving the sealing property.

[0021] Moreover, by arranging an elastic member in the annular body of the seal, the tensile strength of the entire seal can be enhanced, and it can be used under working conditions with higher pressure. A spring is used as the elastic member, which is arranged in a pre-embedded manner before the seal is cast, and can form a better connection with the material after molding, so that the structural stability is stronger and it is more conducive to improving the overall tensile strength.

[0022] At the same time, the obliquely extended sealing front wing and sealing rear wing can not only adapt to the end cover plate structure, but also fit better, thereby improving the sealing performance. The set air holes can facilitate the discharge of air during pouring, thereby improving the molding quality.

[0023] The ball collecting cylinder sealing structure of the utility model can replace the existing sealing parts by adopting the above-mentioned sealing components, and can have a better sealing effect, effectively replace foreign products, and reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] This sealing component is suitable for sealing between the pipeline and the end cover plate 2. The embedding groove 14 formed by the two sealing wings can be easily installed on the end cover plate 2, so that it has excellent wrapping and sealing properties. The two sealing wings have a certain length and can fit well on the end cover plate 2. When there is pressure in the equipment pipeline, the pressure will become tighter and tighter. The pressure can make the seal 1 more tightly press the embedding groove 14 of the end cover plate 2, further improving the sealing property.
