Disclosure of Invention
Aiming at the situation, in order to overcome the defects of the prior art, the utility model provides the flexible polytetrafluoroethylene sealing gasket, which effectively solves the problem that the flexible polytetrafluoroethylene sealing gasket which can still maintain good sealing performance under a long-time extrusion state is required to be provided.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a flexible polytetrafluoroethylene is sealed fills up, includes polytetrafluoroethylene is sealed fills up the body, polytetrafluoroethylene is sealed the inside of filling up the body and is formed the centre bore, polytetrafluoroethylene is sealed the inside of filling up the body and still inlays and be equipped with the metal sheet, polytetrafluoroethylene is sealed all is formed with the round hole that is located same axis on filling up the body and the metal sheet, polytetrafluoroethylene is sealed the inside of filling up the body and still is formed with the passageway, the passageway is located the outside of metal sheet.
Preferably, the metal plate is annular in shape, and is made of aluminum alloy materials.
Preferably, the plurality of channels are provided, the plurality of channels are linearly arranged in the vertical direction, and the cross-sectional shape of the channels is circular.
Preferably, the channel contains a liquid, and the liquid is hydraulic oil.
Preferably, the top and the bottom of the polytetrafluoroethylene sealing gasket body form notches, and reinforcing plates are fixedly connected in the notches.
Compared with the prior art, the utility model has the beneficial effects that:
in operation, the strength of the polytetrafluoroethylene sealing gasket body is enhanced through the metal plate, so that the sealing effect is prevented from being deteriorated after long-time use and deformation; through the passageway that sets up, can produce deformation when its pressurized to make polytetrafluoroethylene sealing pad body's outer wall and by the laminating more of contact surface, thereby further improve sealing performance.
