In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are a subset of the embodiments in the present application and not all embodiments in the present application. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
The transparency mounting seal structure of the present application will be described in further detail with reference to fig. 1.
The application discloses transparent member installation seal structure can include parts such as organism structure 1, transparent member 2, expanded polytetrafluoroethylene sealing tape and connecting bolt.
Specifically, a mounting boss 11 extends vertically from one side of the machine body structure 1, and a mounting hole is formed in the mounting boss 11; in addition, a mounting groove 12 is further formed on one side edge of the top of the machine body structure 1, which is close to the mounting boss 11.
Transparent 2 adaptation is installed at the 11 upper surfaces of installation boss of organism structure 1, runs through on transparent 2 and has seted up the mounting hole, and the top of transparent 2 extends and is provided with the installation limit 21 with mounting groove 12 looks adaptation.
Further, a first expanded polytetrafluoroethylene sealing tape 51 is arranged between the upper surface of the mounting boss 11 and the bottom surface of the transparent member 2; in this embodiment, the first tape 51 is preferably adhered to the upper surface of the mounting boss 11.
Further, a second expanded polytetrafluoroethylene sealing tape 52 is arranged between the upper surface of the mounting groove 12 of the body structure 1 and the bottom surface of the mounting edge 21 of the transparent member 2; in this embodiment, it is also preferable that the second tape 52 is adhered to the upper surface of the mounting groove 2.
The connecting bolt 3 sequentially penetrates through the mounting hole of the transparent part 2, the first expanded polytetrafluoroethylene sealing tape 51 and the mounting hole of the mounting boss 11 from top to bottom from the top of the transparent part 2 and then is in bolted connection with the airtight supporting plate nut 4, so that the fixed connection between the transparent part 2 and the machine body structure 1 is further realized.
The rectifying sealant 7 is filled and sealed from the outside in the remaining gap of the mounting groove 12 of the machine body structure 1.
Further, the sealing structure is installed to transparent piece of this application, can also include the sealed packing ring of expanded polytetrafluoroethylene 6, and its cover is established on connecting bolt 3 to further strengthen sealing performance.
In summary, the sealing structure for mounting the transparent part can realize dry sealing between structures on the premise of meeting the air tightness and water tightness of the structure, and improve the manufacturability and maintenance performance of structure mounting; wherein, relative other sealed glues, the use of expanded polytetrafluoroethylene sealing tape can make bolt dismantlement and the separation between the structure comparatively easy when later maintenance, and can not damage peripheral structure to improve the structural erection maintainability.
The transparent part mounting and sealing structure comprises the following mounting steps:
firstly, cleaning the surface of an installation boss 11 of a machine body structure 1, making a hole, and installing an airtight supporting plate nut 4 on the installation boss 11; a first expanded polytetrafluoroethylene seal tape 51 with a back adhesive is adhered to the upper surface of the mounting boss 11, and a second expanded polytetrafluoroethylene seal tape 52 is adhered to the upper surface of the mounting groove 2. Then placing the transparent part 2 at a designated position and fixing, sleeving the expanded polytetrafluoroethylene sealing washer 6 into the connecting bolt 3, and connecting and fixing the connecting bolt 3 with the airtight supporting plate nut 4 through the transparent part 2 and the mounting boss 11; and finally, filling and sealing the residual gap of the mounting groove 2 by using rectifying sealant 7 from the outer side.
It should be noted that, because the transparent member 2 is difficult to have the same life as the housing structure 1, the expanded ptfe material has poor resilience, and in order to better ensure the sealing performance of the structure, it is recommended to replace the first expanded ptfe sealing tape 51 and the second expanded ptfe sealing tape 52 when the transparent member 2 is replaced.
