Abstract
The utility model relates to a polyfluortetraethylene inner liner pipeline tie-in which comprises two thimbles and a thimble nut. The adjacent ends of the two thimbles are all provided with outer flanges; wherein, the outer circumference of the outer flange of one thimble is provided with an outer thread which matches with the thimble nut, one end of the thimble nut is provided with a necking down, the outer flanges of the two thimbles are mutually butt jointed by the thimble nut, and an airproof mat is arranged between the end surfaces of the two thimbles. The utility model is characterized in that: the outsides of the thimble nut and the thimble which is provided with the outer thread are respectively provided with at least one pair of mutual parallel planes. The utility model has the advantages that: the utility model can be loaded and unloaded by using a common spanner, the operation is therefore much convenient; the edge of the end surface of the outer flange of the thimble is provided with a convex edge which can prevent the airproof mat from radial extending, the bevel of the convex edge is used for compressing the diameter of the airproof mat and all are have the function of airproof capability increasing.
Description
Technical field
The utility model relates to a kind of pipe coupling, specifically is a kind of teflon-lined pipe coupling that has, being connected between being mainly used in the pipeline end and holding.
Background technique
The main structure of existing pipe coupling comprises two sleeve pipes and a sleeve pipe nut, the abutting end of two sleeve pipes is equipped with outward flange, the outer circumferential face of the outward flange of one of them sleeve pipe is provided with the outside thread that cooperates with described sleeve pipe nut, one end of sleeve pipe nut is provided with reducing, the outward flange of two described sleeve pipes docks mutually by sleeve pipe nut, is provided with sealing gasket between two box face.Its shortcoming is that sleeve pipe nut and sleeve pipe outer circumferential face are circle, must could load and unload with the specialized barrel spanner, and is very inconvenient; Seal washer between the box face is radially extensional after reinforcing is fastening, and its sealing can not the corresponding increase with the increase of fastening force.
Summary of the invention
The purpose of this utility model just provides a kind of polytetrafluoroethyllining lining pipe coupling, and the sleeve pipe nut and the sleeve pipe outer circumferential face that exist with the solution prior art are circle, must could load and unload with the specialized barrel spanner, and is very inconvenient; Seal washer between the box face is radially extensional after reinforcing is fastening, the problem that its sealing can not the corresponding increase with the increase of fastening force.
The technical solution of the utility model is: comprise two sleeve pipes and a sleeve pipe nut, the abutting end of two sleeve pipes is equipped with outward flange, the outer circumferential face of the outward flange of one of them sleeve pipe is provided with the outside thread that cooperates with described sleeve pipe nut, one end of sleeve pipe nut is provided with reducing, the outward flange of two described sleeve pipes docks mutually by sleeve pipe nut, between two box face, be provided with sealing gasket, it is characterized in that: be provided with the plane that at least one pair of is parallel to each other separately in the described sleeve pipe nut and the outside that has externally threaded sleeve pipe.
Polytetrafluoroethyllining lining is all established in inboard at described two sleeve pipes.
The opposing side of described two sleeve pipe outward flanges is provided with the convex edge by the edge of one side at least, described sealing gasket is arranged in the groove of this convex edge encirclement, the end face of this convex edge is provided with centroclinal inclined-plane, on the inclined-plane that the outward flange end face of another sleeve pipe relative with it is provided with and described inclined-plane coincide.
The utility model has the advantages that: can use the common wrench loading and unloading, operation is very easy; Be provided with the convex edge in the end face edge of sleeve pipe outward flange and can stop sealing gasket radially to extend, the inclined-plane of convex edge is used for the diameter of compression seal pad, all has the effect that increases sealing.
