[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] The present utility model will be further described in conjunction with the accompanying drawings of the specification.

[0019] The present utility model provides the following technical solutions:

[0020] As shown in the Figures 1-3 accompanying drawings, the present utility model discloses a head with a high-sealing structure, including a head body 2 provided on a container 1. The head body 2 has a head body portion 3 and a head positioning portion 4. The head positioning portion 4 is arranged in a ring structure and sleeved on the head body portion 3. The head body portion 3 and the head positioning portion 4 are fixedly welded together. A head inner sealing positioning ring groove 5 and a head outer sealing positioning ring groove 6 are respectively opened on the head body portion 3 and the head positioning portion 4. The cross-section of the head inner sealing positioning ring groove 5 is arranged in a convex character structure, and the cross-section of the head outer sealing positioning ring groove 6 is arranged in a concave character structure. Specifically, in this design, by respectively arranging the head inner sealing positioning ring groove 5 and the head outer sealing positioning ring groove 6 on the head body portion 2 and the head positioning portion 4, a multi-layer sealing structure can be formed at the connection between the head and the container, thereby greatly improving the sealing performance of the head. First, the convex character structure design of the head inner sealing positioning ring groove 5 can enable the sealing material or sealing gasket to be tightly embedded therein, forming the first internal sealing layer. Such a design can effectively prevent the medium inside the container from leaking out from the connection between the head and the container. Second, the concave character structure design of the head outer sealing positioning ring groove 6 can also tightly accommodate the sealing material or sealing gasket, forming the second external sealing layer. This design not only enhances the connection stability between the head and the container, but also can prevent the medium in the external environment from invading the inside of the container. In addition, since the head body portion 3 and the head positioning portion 4 are fixedly welded together, the entire head structure is more firm, not easily leaking, and easy to process and produce.

[0021] Furthermore, the inner sealing and positioning ring groove 5 of the head has an upper sealing part 7 and a lower sealing part 8. There is a fillet structure 9 between the inner walls of the upper sealing part 7 and the lower sealing part 8. An inner sealing assembly is arranged in the inner sealing and positioning ring groove 5 of the head, and the inner sealing assembly is in sealing connection with the groove wall of the inner sealing and positioning ring groove 5 of the head. Specifically, in this embodiment, the design of the inner sealing and positioning ring groove 5 of the head is more refined. It is composed of the upper sealing part 7 and the lower sealing part 8. The connection between the two adopts a fillet structure 9, making the whole ring groove structure smoother, reducing the possibility of stress concentration, and improving the structural stability. At the same time, the fillet structure 9 also helps the smooth embedding of the inner sealing assembly, further enhancing the sealing effect. The setting of the inner sealing assembly is the key to ensuring the sealing performance of the head. This inner sealing assembly is closely attached to the groove wall of the inner sealing and positioning ring groove 5 of the head, forming a solid sealing barrier. The material and design of the inner sealing assembly need to be selected according to the specific application scenario and medium characteristics to ensure that it has good elasticity and wear resistance and can maintain stable sealing performance for a long time.

[0022] Furthermore, the inner sealing assembly includes a soft sealing ring 10 and a hard sealing ring 11. The soft sealing ring 10 is arranged above the hard sealing ring 11, and the shape of the hard sealing ring 11 is set corresponding to the shape of the inner sealing and positioning ring groove 5 of the head.

[0023] Furthermore, the soft sealing ring 10 is made of nitrile rubber. A sealing sleeve groove 12 is opened on the side of the soft sealing ring 10 close to the hard sealing ring 11. The soft sealing ring 10 is sleeved on the hard sealing ring 11 through the sealing sleeve groove 12, and the shape of the soft sealing ring 10 is set corresponding to the shape of the hard sealing ring 11. Specifically, in this embodiment, the inner sealing assembly adopts a combined design of a soft sealing ring 10 and a hard sealing ring 11. This combination method not only enhances the sealing performance but also improves the durability of the sealing assembly. The soft sealing ring 10 is made of nitrile rubber, which has good elasticity and wear resistance, can effectively fill the tiny gaps between the head and the container, and prevent the leakage of the medium. At the same time, the nitrile rubber material also has excellent oil resistance, water resistance, and chemical corrosion resistance, and can adapt to various harsh working environments. The shape of the hard sealing ring 11 matches the inner sealing and positioning ring groove 5 of the head, which can ensure the stability and sealing performance of the sealing assembly in the ring groove. The soft sealing ring 10 is sleeved on the hard sealing ring 11 through the sealing sleeve groove 12. This design enables the soft sealing ring 10 to be closely attached to the hard sealing ring 11, forming a double sealing barrier. At the same time, the setting of the sealing sleeve groove 12 can also prevent the soft sealing ring 10 from shifting or falling off during the working process, further enhancing the reliability of the sealing assembly.

[0024] Furthermore, an outer sealing ring 13 is arranged in the outer sealing and positioning ring groove 6 of the head, and the outer sealing ring 13 is made of graphite.

[0025] Furthermore, a plurality of positioning holes 14 are equidistantly arranged at the bottom on the side of the head positioning portion 4 away from the center of the head body 2. The cross-section of the positioning hole 14 is semicircular. A positioning end 15 corresponding to the positioning hole 14 is arranged on the container 1, and the positioning end 15 extends into the positioning hole 14 to be connected with the head positioning portion 4. Specifically, in this embodiment, in order to enhance the connection stability between the head and the container, a plurality of positioning holes 14 are also arranged on the head positioning portion 4. The cross-sections of these positioning holes 14 are semicircular, making the edges of the positioning holes 14 smoother and reducing the possibility of stress concentration. The container 1 is correspondingly provided with positioning ends 15, and these positioning ends 15 can extend into the positioning holes 14 and be tightly connected with the head positioning portion 4. Such a design not only enhances the connection strength between the head and the container but also prevents the head from rotating or moving during use.

[0026] Furthermore, a head locking portion 16 and a container locking portion 17 are respectively arranged on the head body 2 and the container 1. The head locking portion 16 is arranged on the side of the head positioning portion 4 away from the head body portion 3, and the head locking portion 16 and the container locking portion 17 are fixedly connected by a bolt 18. Specifically, in this embodiment, in order to further ensure the connection stability and sealing performance between the head and the container, a head locking portion 16 and a container locking portion 17 are also arranged. The head locking portion 16 is located on the side of the head positioning portion 4 away from the head body portion 3 and corresponds to the container locking portion 17. Connecting and fixing the head locking portion 16 and the container locking portion 17 by the bolt 18 can not only enhance the connection strength but also further improve the sealing performance through the pre-tightening force of the bolt.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
