DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] 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.

[0020] Embodiment: Refer to Figures 1-5 , a PTFE-lined steel container in the present utility model includes a top cover 1. A connecting cylinder 2 is provided below the top cover 1. A plurality of fixing bolts 3 are equidistantly arranged between the top cover 1 and the connecting cylinder 2. A first convex plate 6 is provided on the upper part of the connecting cylinder 2, and a second convex plate is provided on the lower part of the top cover 1. Fixing holes 4 for passing through the fixing bolts 3 are formed on the first convex plate 6 and the second convex plate. Through the arrangement of the fixing holes 4 and the fixing bolts 3, the top cover 1 and the connecting cylinder 2 can be better fixed. The split structure of the top cover 1 and the connecting cylinder 2 can facilitate connecting different types of top covers 1 to the connecting cylinder 2, so that the PTFE-lined steel container does not need to be connected to other transfer devices again, making the use of the PTFE-lined steel container simpler; a shoulder 7 is provided at the top of the connecting cylinder 2, and a limit connection groove 8 for clamping the shoulder 7 is formed inside the top cover 1. Through the arrangement of the shoulder 7 and the limit connection groove 8, the top cover 1 can be better fixed and clamped; a rubber pad 5 is provided in the limit connection groove 8 at the top of the shoulder 7. Through the arrangement of the rubber pad 5, a pressing buffer can be provided for the mutually pressed top cover 1 and the connecting cylinder 2, thereby improving the connection sealing performance of the top cover 1.

[0021] In the present utility model, a support limit plate 9 for extending into the connecting cylinder 2 is provided at the side end of the limit connection groove 8. The support limit plate 9 is a straight cylinder connecting plate that abuts against the inner wall of the connecting cylinder 2. Through the arrangement of the support limit plate 9, the connecting cylinder 2 can be better abutted, and support can be provided for the end of the connecting cylinder 2, thereby improving the support stability of the device; a plurality of first sealing convex rings 10 for abutting against the inner wall of the connecting cylinder 2 are equidistantly arranged on the upper part of the support limit plate 9. Through the arrangement of the plurality of first sealing convex rings 10, the inner wall of the connecting cylinder 2 can be better abutted, thereby improving the connection airtightness of the device; a second sealing convex ring 11 is provided at the lower end of the lower part of the support limit plate 9, and a chamfer is formed on the outer side of the lower part of the second sealing convex ring 11. Through the arrangement of the second sealing convex ring 11 and the chamfer, the support limit plate 9 can be better extended into the connecting cylinder 2, and a first layer of sealing can be provided for the device, reducing the pressure borne by the subsequent sealing device and improving the service life of the sealing mechanism in the device.

[0022] Working principle: When the utility model is used, first put the rubber pad 5 into the limiting connection groove 8, and then insert the top cover 1 into the connecting tube 2. During the insertion process, the chamfer of the second sealing convex ring 11 first abuts against the inner wall of the connecting tube 2. The chamfer set on the second sealing convex ring 11 can make the support limiting plate 9 more labor-saving to insert into the connecting tube 2. The setting of the second sealing convex ring 11 and the chamfer can better extend the support limiting plate 9 into the connecting tube 2, and provide the first layer of sealing for the device, reduce the pressure borne by the subsequent sealing device, and improve the service life of the sealing mechanism in the device. Then, fix the fixing bolt 3 in the fixing hole 4. The tightening of the fixing bolt 3 will cause the boss 7 to press the rubber pad 5 in the limiting connection groove 8, thereby enhancing the connection air tightness of the device. At this point, the installation of the steel-lined PTFE container is completed.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
