Abstract
The invention discloses a guide sleeve for mechanical seal, comprising a main part with an annular section and a mounting part protruding and extending from one end of the main part to the periphery; the side, facing to the main part, of the mounting part is concavely arranged to form an annular sealing groove; the main part is provided with a first cavity communicating along the axial direction and having a first diameter; the mounting part is provided with a second cavity with a second diameter and a third cavity of which the diameter is gradually changed; the third cavity communicates between the first cavity and the second cavity; and the first diameter is smaller than the second diameter. The guide sleeve disclosed by the invention is simple in structure and good in sealing effect.
Description
Technical field
The application belongs to technical field of mechanical, particularly relates to a kind of flow guide sleeve 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 flow guide sleeve for mechanical seal, to overcome in prior art
Not enough.
For achieving the above object, the present invention provides following technical scheme:
The embodiment of the present application discloses a kind of flow guide sleeve for mechanical seal, including the master of ring-shaped section and ring-shaped
The installation portion that one end of body and main body protrudes out to surrounding, described installation portion is towards described main body
The side in portion is recessed is formed with the seal groove of annular, described main part have communicate vertically have first
First cavity of diameter, described installation portion has the second cavity and the change of diameter gradually property of Second bobbin diameter
The 3rd cavity, described 3rd cavity is communicated between described first cavity and the second cavity, described first
Diameter is less than described Second bobbin diameter.
Preferably, in the above-mentioned flow guide sleeve for mechanical seal, described seal groove and described main part
Outer wall between be formed with stage portion.
Preferably, in the above-mentioned flow guide sleeve for mechanical seal, the sidewall of described installation portion is vertically
Offer the hole, location that cross section is curved.
Preferably, in the above-mentioned flow guide sleeve for mechanical seal, the recessed shape in edge of described installation portion
Cheng Youyi breach.
Compared with prior art, it is an advantage of the current invention that: the flow guide sleeve simple in construction of the present invention, seal
Effective.
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 flow guide sleeve in the specific embodiment of the invention；
Fig. 2 show the side view of flow guide sleeve 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.
Ginseng Fig. 1 and Fig. 2 shown in, the flow guide sleeve for mechanical seal include ring-shaped section and ring-shaped main part 1,
And the installation portion 2 that one end of main body protrudes out to surrounding, the recessed shape in side in installation portion agent-oriention portion
Becoming the seal groove 3 having annular, main part has first cavity 4 with the first diameter communicated vertically,
Installation portion has the second cavity 5 and the 3rd cavity 6 of diameter gradually property change, the 3rd chamber of Second bobbin diameter
Body is communicated between the first cavity and the second cavity, and the first diameter is less than Second bobbin diameter.
Further, stage portion 7 it is formed with between seal groove and the outer wall of main part.
Further, the sidewall of installation portion offers the hole, location 8 that cross section is curved vertically.
Further, the edge of installation portion is recessed is formed with a breach 9.
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.
