The utility model discloses a gland simple structure, it is sealed effectual.
Description
Technical field
The application belongs to technical field of mechanical, particularly relates to a kind of gland for mechanical seal.
Background technique
The leakage problem of large-scale mixing plant or conveying equipment is the problem that the industry device such as chemical industry, pharmacy manufacturer pays close attention to most always.During for transport pump water or other liquid; leakage problem is caused due to poorly sealed; a lot of producer adds oil sealing to increase the sealing of equipment; but oiling is honored as a queen, axle sleeve is easy to just be destroyed; cause the machine envelope life-span extremely short; also do not have suitable product to protect in the market, therefore in equipment runs, liquid pours out flowing, destroys other equipment.
Model utility content
The purpose of this utility model is to provide a kind of gland for mechanical seal, not enough to overcome in prior art.
For achieving the above object, the utility model provides following technological scheme:
The embodiment of the present application discloses a kind of gland for mechanical seal, comprise main part, this main part has a through hole axially communicated, the outer side wall of described main part protrudes out the assembly department of annular to surrounding, described assembly department offers the first mounting hole vertically, described through hole comprises first through hole with the first diameter, there is the second through hole of Second bobbin diameter, and there is the third through-hole of the 3rd diameter, described first diameter is greater than Second bobbin diameter, described Second bobbin diameter is greater than described 3rd diameter, described second through hole is communicated between described first through hole and third through-hole, stepped part is formed between described first through hole and the second through hole, described stepped part is formed with the second mounting hole vertically.
Preferably, above-mentioned in the gland of mechanical seal, described assembly department presses close to one end recessed seal groove being formed with annular vertically of described main part.
Preferably, above-mentioned in the gland of mechanical seal, the edge of opening of described first through hole is formed with chamfering.
Preferably, above-mentioned in the gland of mechanical seal, the edge of described stepped part is formed with chamfering.
Compared with prior art, the utility model has the advantage of: gland structure of the present utility model is simple, good sealing effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Figure 1 shows that the structural representation of gland in the utility model specific embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be described in detail the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, belongs to the scope of the utility model protection.
Shown in ginseng Fig. 1, for the gland of mechanical seal, comprise main part 1, this main part has a through hole 2 axially communicated, the outer side wall of described main part protrudes out the assembly department 3 of annular to surrounding, described assembly department 3 offers vertically the first mounting hole 4, described through hole comprises first through hole 5 with the first diameter, there is the second through hole 6 of Second bobbin diameter, and there is the third through-hole 7 of the 3rd diameter, described first diameter is greater than Second bobbin diameter, described Second bobbin diameter is greater than described 3rd diameter, described second through hole is communicated between described first through hole and third through-hole, stepped part 8 is formed between described first through hole and the second through hole, described stepped part is formed with the second mounting hole 9 vertically.
Further, described assembly department presses close to one end recessed seal groove 10 being formed with annular vertically of described main part.
Further, the edge of opening of described first through hole is formed with chamfering 11.
Further, the edge of described stepped part is formed with chamfering 12.
The end face of assembly department 3 offers between the 3rd mounting hole the 13, three mounting hole 13 and the first through hole along the direction of vertical axial and is communicated with oil hole 14.
It should be noted that, in this article, the such as relational terms of first and second grades and so on is only used for an entity or operation to separate with another entity or control panel, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.And, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising described key element and also there is other identical element.
The above is only the embodiment of the application; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of the application.
