Technical Field

[0001] The utility model relates to the technical field of sealing components, in particular to a wear-resistant and durable sealing component. Background Art

[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent mating surfaces and prevent foreign matter such as dust and moisture from invading the internal parts of machinery and equipment. Existing seals are used to improve their wear resistance by replacing the damaged parts of the seals, but the replacement is often done through external accessories, which makes installation more troublesome and increases production costs, and the wear resistance of the seal itself is not changed. Utility Model Content

[0003] The utility model aims to provide a wear-resistant and durable sealing component in view of the problems existing in the background technology.

[0004] The technical solution of the utility model is: a wear-resistant and durable seal, including a seal composed of a first sealing strip body and a second sealing strip body, the first sealing strip body and the second sealing strip body are connected into a ring shape by docking components arranged at both ends, the first sealing strip body has a T-shaped groove in the inner circle, and the second sealing strip body has a T-shaped strip adapted thereto in the outer circle, and the T-shaped strip is slidably installed in the T-shaped groove when in use.

[0005] Preferably, the inner wall of the T-shaped groove is a reinforcing steel sheet arranged in the first sealing strip body, and the reinforcing steel sheet and the T-shaped groove are made of the same material.

[0006] Preferably, the docking assembly includes a fixing hole opened at one end of the first sealing strip body and the second sealing strip body, and also includes a fixing plug installed at the other end of the first sealing strip body and the second sealing strip body.

[0007] Preferably, an L-shaped baffle is provided on the top of the second sealing strip body, and the size of the area between the L-shaped baffle and the second sealing strip body is adapted to the first sealing strip body.

[0008] Preferably, a guide strip is provided inside the L-shaped baffle, and a guide groove adapted to the guide strip is formed on the outer ring of the first sealing strip body.

[0009] Preferably, the second sealing strip body is provided with a wear-resistant coating.

[0010] Compared with the prior art, the utility model has the following beneficial effects: by dividing the seal into a first sealing strip body and a second sealing strip body, the second sealing strip body can be replaced after long-term wear, and the second sealing strip body is arranged to slide in the first sealing strip body, which first facilitates replacement and changes the original sealing method of being connected by bolts. Moreover, because the second sealing strip body is arranged to slide, when a pipeline is inserted into the second sealing strip body, because the pipeline is generally inserted in a rotating manner, the second sealing strip body will rotate with the rotation of the pipeline, which can reduce friction, thereby improving wear resistance from this aspect.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] See attached Figure 1-4, a wear-resistant and durable seal, including a seal consisting of a first sealing strip body 1 and a second sealing strip body 2, the first sealing strip body 1 and the second sealing strip body 2 are connected to form a ring shape by docking components arranged at both ends, the inner ring of the first sealing strip body 1 is provided with a T-shaped groove 3, and the outer ring of the second sealing strip body 2 is provided with a T-shaped strip 4 adapted thereto, and the T-shaped strip 4 is slidably installed in the T-shaped groove 3 when in use, and the seal is divided into the first sealing strip body 1 and the second sealing strip body 2, so that the second sealing strip body 2 can be replaced after long-term wear, and the setting that the second sealing strip body 2 slides in the first sealing strip body 1 is first convenient for replacement, and the original sealing method of bolt connection is changed, and because the second sealing strip body 2 is a slidable setting, when a pipe is inserted into the second sealing strip body 2, because the pipe is generally inserted in a rotating manner, the second sealing strip body 2 will rotate with the rotation of the pipe at this time, which can reduce friction, thereby improving wear resistance from this aspect.

[0018] It should be noted that the inner wall of the T-shaped groove 3 is a reinforcing steel sheet 8 arranged in the first sealing strip body 1. The reinforcing steel sheet 8 and the T-shaped groove 3 are made of the same material. Through this arrangement, firstly, it is similar to adding reinforcing ribs in the first sealing strip body 1, and the reinforcing steel sheet 8 and the T-shaped groove 3 are both stainless steel sheets with high toughness, which ensures that the first sealing strip body 1 and the second sealing strip body 2 can form a ring shape normally, and ensures that the sliding of the T-shaped strip 4 in the T-shaped groove 3 is more stable and will not be deformed by external force. The docking assembly includes a plurality of reinforcing steel sheets 8 and a plurality of reinforcing steel sheets 8. The fixing hole 9 at one end of the sealing strip body 2 also includes a fixing plug 10 installed at the other end of the first sealing strip body 1 and the second sealing strip body 2. When the seal is installed, the T-shaped strip 4 is first inserted into the T-shaped groove 3, and then the T-shaped strip 4 is completely placed in the T-shaped groove 3, so that the second sealing strip body 2 will completely overlap with the first sealing strip body 1, and then the first sealing strip body 1 and the second sealing strip body 2 are completely connected to form a ring shape, and then the fixing plug 10 is inserted into the fixing hole 9 to connect the two ends of the first sealing strip body 1 and the second sealing strip body 2, so that the seal is formed.

[0019] It should be further explained that an L-shaped baffle plate 5 is provided on the top of the second sealing strip body 2, and the area between the L-shaped baffle plate 5 and the second sealing strip body 2 is adapted to the first sealing strip body 1. The outer ring of the first sealing strip body 1 is provided with a guide groove 7 adapted to the guide strip 6. Figure 2 and 3 As shown, when the T-shaped strip 4 is inserted into the T-shaped groove 3, the guide strip 6 will also be inserted into the guide groove 7. In this way, when the first sealing strip body 1 and the second sealing strip body 2 form a seal, the L-shaped baffle 5 will wrap the first sealing strip body 1, so that the sealing performance will not be reduced due to the gap between the first sealing strip body 1 and the second sealing strip body 2. The second sealing strip body 2 is provided with a wear-resistant coating 11.
