Abstract
The invention relates to the field of flanges, in particular to a double-layer sealing type flange. The double-layer sealing type flange comprises a welding section, a changing section and a sealing gasket, wherein the sealing gasket is arranged between the welding section and the changing section; the welding section is arranged on the left side of the sealing gasket; the left side surface of the welding section and a port of a pipeline are welded; threaded holes are formed in the middle part of the right side surface of the welding section; annular bulges are further arranged on the right side surface of the welding section; annular notches are formed in the inner edge of the right side surface of the welding section; the changing section is positioned on the right side of the sealing gasket; annular flanges are arranged on the inner edge of the left side surface of the changing section; the flanges are matched with the notches; and connecting holes are further formed in the changing section. According to the double-layer sealing type flange, a traditional flange is divided into front and back sections, and the gasket is arranged between the two sections, so that the flange can be directly changed when the flange end face rusts, cannot be opened and is damaged.
Description
Technical field
The present invention relates to flange field, a kind of double-layer seal type flange.
Background technology
Flange is to make pipe and the interconnective part of pipe, is connected to pipe end, and after using for a long time, the joint face of flange often gets rusty, and is difficult to separately owing to being bonded to each other during replacing, makes troubles to workman.
Summary of the invention
For the problems of the prior art, the invention provides a kind of double-layer seal type flange, including welding section, change section and gasket seal；Described gasket seal is arranged on welding section and changes between section.
Described welding section is arranged on the left of gasket seal, and welding section left surface welds with pipe end, is provided with screwed hole in the middle part of welding section right flank, and welding section right flank is additionally provided with annular protrusion, and welding section right flank inner edge is provided with annular breach.
Described replacing section is positioned on the right side of gasket seal, and the inner edge changing section left surface is provided with annular flange flange, and this flange is formed with breach and coordinates, and changes and is additionally provided with connecting hole in section.
Preferably, described gasket seal ringwise, the rough surface of gasket seal, gasket seal is provided with through hole.
Preferably, described projection includes the different outer ring of radius and inner ring.
The invention has the beneficial effects as follows: a kind of double-layer seal type flange of the present invention, traditional flange is divided into before and after two sections, and accompanies pad between two sections so that end face of flange gets rusty and can directly replace when cannot open or damage.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of section of the present invention；
In figure: welding section (1), replacing section (2), gasket seal (3), breach (11), protruding (12), screwed hole (13), flange (21), through hole (31).
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with detailed description of the invention, the present invention is expanded on further.
As it is shown in figure 1, a kind of double-layer seal type flange of the present embodiment, including welding section 1, change section 2 and gasket seal 3；Described gasket seal 3 is arranged on welding section 1 and changes between section 2.
Described welding section 1 is arranged on the left of gasket seal 3, welding section 1 left surface welds with pipe end, being provided with screwed hole 13 in the middle part of welding section 1 right flank, welding section 1 right flank is additionally provided with annular protrusion 12, welding section 1 right flank inner edge is provided with annular breach 11.
Described replacing section 2 is positioned on the right side of gasket seal 3, and the inner edge changing section 2 left surface is provided with annular flange flange 21, and this flange 21 is formed with breach 11 and coordinates, and changes and is additionally provided with connecting hole 22 in section 2.
Described gasket seal 3 ringwise, the rough surface of gasket seal 3, gasket seal 3 is provided with through hole 31.
Described projection 12 includes the different outer ring of radius and inner ring.
In use, welding section 1 and replacing section 2 are separated a kind of double-layer seal type flange of embodiment by gasket seal 3 so that end face of flange gets rusty and can directly replace when cannot open or damage.
The general principle of the present invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described of the description in above-mentioned embodiment and specification; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the scope of protection of present invention.Claimed scope is defined by appending claims and equivalent thereof.
