Abstract
The invention discloses a thread telescopic shell cover. The thread telescopic shell cover comprises a shell cover body which is a cavity structure formed by connecting an arc curved surface with a cylinder structure. A graphite layer is arranged on the inner surface of a cylinder body of the shell cover body. A thread structure is arranged on the inner surface of the graphite layer. An adjustment pipeline is screwed on the thread structure. A thread is arranged on the outer surface of the adjustment pipeline. A seal washer is arranged on the edge of an opening in the bottom of the shell cover body. By means of the manner, the shell cover is simple in structure, has a telescopic function, can be adjusted to be stretched out and drawn back during installation, and is high in practicability and good in sealing performance.
Description
Technical field
The present invention relates to end socket field, particularly relate to a kind of screw telescopic formula end socket.
Background technology
End socket is the end cap on pressure vessel, is a main pressure-containing member of pressure vessel.Role is sealing function.One be made as tank shape pressure vessel on go to the bottom, two is that pipeline reaches an end, and does not prepare to extend further along, and that just seals up in the form that pipe is welded with an end socket.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of screw telescopic formula end socket, it is possible to can be adjusted when mounted stretching, practical, good airproof performance.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of screw telescopic formula end socket, it is characterized in that, including: end socket main body, described end socket main body is to be connected, by a circular arc camber and cylindrical structure, the cavity structure formed, it is provided with a graphite linings on the cylinder inner surface of described end socket main body, it is provided with helicitic texture on described graphite linings inner surface, a regulation pipeline has been screwed on described helicitic texture, described regulation pipeline external surface is provided with screw thread, wherein, it is provided with a seal washer on the bottom opening edge of described end socket main body.
In a preferred embodiment of the present invention, described graphite linings uses material to be expanded graphite.
In a preferred embodiment of the present invention, the both ends open edge of described regulation pipeline is provided with caulking gum.
In a preferred embodiment of the present invention, described helicitic texture matches with the screw thread regulating pipe surface and screws.
The invention has the beneficial effects as follows: end enclosure structure provided by the present invention is simple, has Telescopic, can be adjusted when mounted stretching, practical, good airproof performance.
