Abstract

The invention discloses a push ring used for mechanical seal. The push ring comprises a main portion, the main portion is provided with an axial communication through hole, a first annular protruding stretching portion is arranged on the outer side wall of the main portion in a manner of protruding and stretching towards the periphery, and third second protruding stretching portions are arranged at the end of the main portion in the axial direction in a protruding stretching manner. The push ring is simple in structure and good in seal effect.

Description

A kind of throw-out collar for mechanical seal

Technical field

The application belongs to technical field of mechanical, particularly relates to a kind of throw-out collar for mechanical seal.

Background technology

Large-scale mixing plant or the leakage problem of conveying equipment, the always industry device such as chemical industry, pharmacy are raw The problem that business men is paid close attention to most.During for transport pump water or other liquid, leakage is caused to be asked due to poorly sealed Topic, a lot of producers add the oil sealing sealing with increase equipment, but oiling is honored as a queen, axle sleeve is easy to just be destroyed, Cause the machine envelope life-span extremely short, the most also do not have suitable product to protect, therefore run at equipment Middle liquid pours out flowing, destroys other equipment.

Summary of the invention

It is an object of the invention to provide a kind of throw-out collar for mechanical seal, to overcome in prior art not Foot.

For achieving the above object, the present invention provides following technical scheme:

The embodiment of the present application discloses a kind of throw-out collar for mechanical seal, including main part, this main part Having a through hole axially communicated, the lateral wall of described main part protrudes out annular first to surrounding and protrudes out Portion, the end of described main part has protruded out three the second convex extension parts vertically.

Preferably, in the above-mentioned throw-out collar for mechanical seal, described three the second convex extension parts are equidistant Arrange.

Preferably, in the above-mentioned throw-out collar for mechanical seal, the edge of described first convex extension part is along hanging down Straight axial direction has protruded out four the 3rd convex extension parts.

Preferably, in the above-mentioned throw-out collar for mechanical seal, described four the 3rd convex extension parts are equidistant Arrange.

Preferably, in the above-mentioned throw-out collar for mechanical seal, described 3rd convex extension part has arc Surface.

Compared with prior art, it is an advantage of the current invention that: the throw-out collar simple in construction of the present invention, seal effect The best.

Accompanying drawing explanation

In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to reality Execute the required accompanying drawing used in example or description of the prior art to be briefly described, it should be apparent that below, Accompanying drawing in description is only some embodiments described in the application, for those of ordinary skill in the art From the point of view of, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 show the structural representation of throw-out collar in the specific embodiment of the invention；

Fig. 2 show the top view of throw-out collar in the specific embodiment of the invention.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out Detailed description, it is clear that described embodiment is only a part of embodiment of the present invention rather than complete The embodiment in portion.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation Property work on the premise of the every other embodiment that obtained, broadly fall into the scope of protection of the invention.

Shown in ginseng Fig. 1, for the throw-out collar of mechanical seal, including main part 1, this main part 1 has an axle To the through hole 2 communicated, the lateral wall of described main part protrudes out the first convex extension part 3 of annular, institute to surrounding The end stating main part has protruded out three the second convex extension parts 4 vertically.

Further, described three the second convex extension part spaced sets.

Further, the edge of described first convex extension part has protruded out four the 3rd along vertical axial direction and has protruded out Portion 5.

Further, described four the 3rd convex extension part spaced sets.

Further, described 3rd convex extension part has the surface of arc.

It should be noted that in this article, the relational terms of such as first and second or the like is used merely to One entity or operation are separated with another entity or operating space, and not necessarily requires or imply Relation or the order of any this reality is there is between these entities or operation.And, term " includes ", " comprise " or its any other variant is intended to comprising of nonexcludability, so that include that one is The process of row key element, method, article or equipment not only include those key elements, but also include the brightest Other key elements really listed, or also include intrinsic for this process, method, article or equipment Key element.In the case of there is no more restriction, statement " including ... " key element limited, It is not precluded from there is also in including the process of described key element, method, article or equipment other identical Key element.

The above is only the detailed description of the invention of the application, it is noted that general for the art For logical technical staff, on the premise of without departing from the application principle, it is also possible to make some improvement and profit Decorations, these improvements and modifications also should be regarded as the protection domain of the application.
