The copper sleeve is arranged in the mounting hole of the polytetrafluoroethylene gasket; the utility model discloses simple structure can guarantee under the highly compressed operational environment of high temperature that the sealing washer is difficult for taking place to warp, has good supporting role, does not influence original pipeline circulation, has reduced the change frequency, safe and reliable of sealing washer.

Description

Novel high-temperature-resistant sealing ring
Technical Field
The utility model belongs to the technical field of the tenon joint is sealed for the tobacco equipment, concretely relates to novel high temperature resistant sealing washer.
Background
In the daily use process of some tobacco equipment, the connection part of the pipeline can cause the deformation of the original polytetrafluoroethylene sealing ring under the long-term high-temperature and high-pressure steam-liquid flushing, sometimes even cause the blockage of a connection port, thereby not playing a corresponding sealing role. If the sealing ring is not replaced in time, potential safety hazards such as air leakage and liquid leakage can occur.
Disclosure of Invention
In order to overcome the problems of potential safety hazards such as deformation of a sealing ring, blockage of a connecting port, even leakage of gas and liquid and the like frequently occurring at the connecting part of a pipeline under the long-term scouring of high-temperature and high-pressure vapor and liquid in the background technology, the utility model provides a novel high-temperature resistant sealing ring which can ensure that the sealing ring is not easy to deform under the high-temperature and high-pressure working environment; the replacement frequency of the sealing ring is reduced, and the sealing ring is safe and reliable.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the utility model provides a novel high temperature resistant sealing washer mainly includes polytetrafluoroethylene packing ring, red copper sheathing, polytetrafluoroethylene packing ring middle part be equipped with the mounting hole, red copper sheathing is installed in the mounting hole of polytetrafluoroethylene packing ring.
The red copper sleeve is in interference fit with the mounting hole of the polytetrafluoroethylene gasket.
The two ends of the red copper sleeve are of horn mouth structures.
The utility model has the advantages that:
the utility model discloses simple structure can guarantee under the highly compressed operational environment of high temperature that the sealing washer is difficult for taking place to warp, and increase of service life has good supporting role, does not influence original pipeline circulation, has reduced the change frequency, safe and reliable of sealing washer.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
The utility model discloses a novel high temperature resistant sealing ring, which mainly comprises a polytetrafluoroethylene gasket 1 and a red copper sleeve 2, wherein the middle part of the polytetrafluoroethylene gasket 1 is provided with a mounting hole, and the red copper sleeve 2 is arranged in the mounting hole of the polytetrafluoroethylene gasket 1; the polytetrafluoroethylene gasket 1 ensures tenon connection sealing and sealing effect; the red copper bush 2 plays a supporting role in the polytetrafluoroethylene gasket 1, the polytetrafluoroethylene gasket 1 is guaranteed not to be prone to deformation, a good supporting role is achieved, meanwhile, the inner wall of the red copper bush 2 serves as a working face of the inner wall of the pipeline, high-temperature and high-pressure steam and liquid are prevented from scouring the polytetrafluoroethylene gasket 1, and the service life is prolonged.
The red copper sleeve 2 is in interference fit with the mounting hole of the polytetrafluoroethylene gasket 1, so that the red copper sleeve 2 is not easy to fall off in the using process.
The two ends of the red copper sleeve 2 are in a bell mouth structure, and the inner surface of the bell mouth structure can ensure better circulation in the use process; the outer surface of the bell mouth structure can ensure reliable matching with the polytetrafluoroethylene gasket 1 and is not easy to fall off.
The working process is as follows:
the novel high-temperature-resistant sealing ring is arranged in a concave structure of tenon connection, the convex structure and the concave structure are in tenon connection, and the convex structure and the concave structure extrude the two ends of the novel high-temperature-resistant sealing ring to be in close contact with the polytetrafluoroethylene gasket 1, so that sealing is realized; the inner wall of the red copper sleeve 2 serves as a working surface of the inner wall of the pipeline, so that high-temperature and high-pressure vapor and liquid are prevented from scouring the polytetrafluoroethylene gasket 1, and the service life is prolonged.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
