When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] For examples, see Figure 1-4 , the utility model provides a technical solution:

[0027] A PTFE equipment lining installation device includes an equipment body 1 and a top cover 2 arranged on the top of the equipment body 1. The top surface of the equipment body 1 is provided with a groove 3. The equipment body 1 is provided with an equipment compartment 4. The equipment compartment 4 is provided with a PTFE lining 5. A mounting mechanism 6 is provided between the PTFE lining 5 and the equipment compartment 4. The interior of the PTFE lining 5 is provided with a metal mesh 501, a glass fiber 502, and a PTFE film layer 503.

[0028] Specifically, the top inner wall of the equipment compartment 4 extends to the bottom inner wall of the groove 3, the inner surface of the metal mesh 501 contacts the outer surface of the glass fiber 502, and the inner surface of the glass fiber 502 contacts the outer surface of the polytetrafluoroethylene film layer 503. The metal mesh 501, the glass fiber 502, and the polytetrafluoroethylene film layer 503 are integrally sintered at high temperature.

[0029] In this embodiment, the combination of the metal mesh 501, the glass fiber 502 and the PTFE film layer 503 enhances the structural strength of the PTFE lining 5, so that it can maintain good shape and sealing performance when subjected to high temperature, high pressure or corrosive media.

[0030] In this embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 The mounting mechanism 6 includes a limiting groove 601, a limiting strip 602, a mounting column 603 and a mounting ring block 604. The limiting groove 601 is provided on the inner wall of the bottom end of the groove 3. The limiting strip 602 is fixedly mounted on the outer surface of the polytetrafluoroethylene liner 5. The mounting column 603 is fixedly mounted on the inner wall of the bottom end of the groove 3. The mounting ring block 604 is fixedly arranged on the top surface of the polytetrafluoroethylene liner 5, and a mounting hole 605 is provided on the top surface thereof.

[0031] Specifically, the limiting grooves 601 and the mounting posts 603 are equidistantly distributed in a circular pattern about the bottom inner wall of the groove 3. The limiting grooves 601 have a T-shaped cross-section and are in corresponding contact with the limiting bars 602. The bottom inner wall of the mounting hole 605 extends to the bottom of the mounting ring block 604, and its inner wall contacts the mounting posts 603. The top surface of the mounting ring block 604 is flush with the top inner wall of the groove 3.

[0032] In this embodiment, the limiting groove 601 is set to form a fitting contact with the limiting bar 602, ensuring the positioning of the polytetrafluoroethylene lining 5 in the equipment bin 4. Under the contact between the mounting hole 605 and the mounting column 603, the mounting ring block 604 is tightly attached to the groove 3, thereby achieving the effect of firmly installing the polytetrafluoroethylene lining 5, effectively avoiding the displacement of the polytetrafluoroethylene lining 5 due to thermal expansion and contraction during use, improving the stability of the polytetrafluoroethylene lining 5, and meeting the use requirements of the equipment.

[0033] The working process of the present utility model is as follows: when using a PTFE equipment lining installation device, the PTFE lining 5 is first moved so that the PTFE lining 5 drives the limiting bar 602 to be close to and contact the limiting groove 601. Under the sliding fit of the limiting bar 602 and the limiting groove 601, the installation ring block 604 gradually approaches the groove 3, and then the installation hole 605 contacts the installation column 603 until the top surface of the installation ring block 604 is flush with the top inner wall of the groove 3, thereby completing the installation of the PTFE lining 5. Under the contact and cooperation between the limiting groove 601 and the limiting bar 602, the stability between the PTFE lining 5 and the equipment bin 4 is improved, and the installation effect of the PTFE lining 5 is improved. At the same time, through the integrated setting of the metal mesh 501, the glass fiber 502 and the PTFE film layer 503, the structural strength of the PTFE lining 5 is effectively enhanced, the service life of the PTFE lining 5 is improved, and it is beneficial to subsequent use.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
