Abstract
The utility model provides a butterfly valve sealing ring with a widened sealing surface, and particularly relates to the field of valve sealing rings. The problem that there is design defect in order to solve the current sealing washer terminal surface that exists among the prior art and receive the influence of sealing washer terminal surface plane degree in actual processing and use includes: sealing washer body and seal line. Compare for planar sealing washer with original terminal surface, four sealing lines that this sealing washer has are when compressing tightly with the flange terminal surface, the sealing line receives the extrusion and closely laminates with the flange terminal surface, four sealing lines have formed the multiple seal, the sealed face has been widened, sealing performance has further been promoted, simultaneously in the pipeline low pressure leakage thing through three preceding sealing lines is blockked in the annular region between two sealing lines in the outside, the sealing line top wedge position in the outside can be better when compressing tightly with the flange terminal surface block the low pressure leakage thing that three preceding sealing lines overflowed.
Description
Technical Field
The utility model relates to a device in the field of valve sealing rings, in particular to a butterfly valve sealing ring with a widened sealing surface.
Background
The flange butterfly valve has the advantages of simple structure, small volume, light weight, simple operation and good fluid control property, and only consists of a few parts. The flange butterfly valve is usually provided with an elastic sealing ring, the elastic sealing ring is attached to the periphery of the butterfly plate, and the two ends of the sealing ring are in contact with the end face of the flange to compress the flange to seal the valve. The existing sealing ring end face has design defects, the end face is usually designed into a plane configuration, the end face is influenced by the flatness of the end face of the sealing ring in the actual processing and using processes, the contact surface is often uneven in pressure and even forms point contact, the effect is not ideal during sealing, the sealing reliability is not high, and particularly under the environment of high pipeline pressure, the requirement on the sealing performance of a valve is higher, so that the higher requirement is also put forward on the sealing surface.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a butterfly valve sealing ring with a widened sealing surface, which aims to solve the problems in the prior art. The technical effects that can be produced by the preferred technical scheme in the technical schemes provided by the utility model are described in detail in the following.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a butterfly valve sealing ring with a widened sealing surface, which comprises: the sealing ring comprises a sealing ring body and four sealing lines, wherein the four sealing lines are fixedly arranged on the end faces of the two sides of the sealing ring body, are of a closed circular ring configuration and are arranged concentrically.
Preferably, the tops of the cross sections of the three sealing lines close to the inner side of the sealing ring body are in an arc configuration, and the top end of the cross section of one sealing line close to the outermost side of the sealing ring body is in a wedge shape.
Preferably, the three sealing lines close to the inner side of the sealing ring body are arranged at equal intervals, and the interval between the sealing line close to the outermost side of the sealing ring body and the adjacent sealing line is greater than the interval between the three sealing lines close to the inner side of the sealing ring body.
The butterfly valve sealing ring with the widened sealing surface has the beneficial effects that: compare for planar sealing washer with original terminal surface, four sealing lines that this sealing washer has are when compressing tightly with the flange terminal surface, the sealing line receives the extrusion and closely laminates with the flange terminal surface, four sealing lines have formed the multiple seal, the sealed face has been widened, sealing performance has further been promoted, simultaneously in the pipeline low pressure leakage thing through three preceding sealing lines is blockked in the annular region between two sealing lines in the outside, the sealing line top wedge position in the outside can be better when compressing tightly with the flange terminal surface block the low pressure leakage thing that three preceding sealing lines overflowed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
The following describes in detail a specific embodiment of the present invention with reference to the drawings. In the drawings, the same reference numerals indicate the same or corresponding features. The figures are only schematic and are not necessarily drawn to scale.
Referring to fig. 1 and 2, a butterfly valve seal ring with a widened sealing surface as shown comprises: sealing washer body 1 and sealing line 2, four sealing lines 2 have all set firmly to the both sides terminal surface of sealing washer body 1, and sealing line 2 is the closed ring configuration, and four sealing lines 2 set up with one heart.
The top of the cross section of three sealing lines close to the inner side of the sealing ring body 1 is in an arc configuration, the arc can be attached to the end face of the flange more closely, and the top of the cross section of one sealing line close to the outermost side of the sealing ring body 1 is in a wedge shape.
The three sealing lines close to the inner side of the sealing ring body 1 are arranged at equal intervals, and the interval between the sealing line close to the outermost side of the sealing ring body 1 and the adjacent sealing line is larger than the interval between the three sealing lines close to the inner side of the sealing ring body 1.
Compare for planar sealing washer with original terminal surface, four sealing lines that this sealing washer has are when compressing tightly with the flange terminal surface, the sealing line receives the extrusion and closely laminates with the flange terminal surface, four sealing lines have formed the multiple seal, the sealed face has been widened, sealing performance has further been promoted, simultaneously in the pipeline through the less and pressure of leakage quantity of preceding three sealing lines, low pressure leakage thing is blockked in the annular region between two sealing lines in the outside, the sealing line top wedge position in the outside can be better when compressing tightly with the flange terminal surface block the low pressure leakage thing that preceding three sealing lines spilled over.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
