Abstract
A ventilation plug is characterized in that the ventilation plug comprises a plug body, a plug cover and a filtering layer, an inner cavity vertically penetrating through the plug body in the axial direction is formed in the plug body, the bottom of the plug body is vertically fixed to the top of a bearing chamber, the top of the plug body is connected with the plug cover in a sealed mode, the filtering layer is arranged between the plug cover and the end face of the top of the plug body in a pressed mode, the outer side face of the plug body is provided with a notch, and the end face of the top of the plug body is provided with a ventilation hole communicated with the notch in the axial direction. According to the combined ventilation plug, air enters the plug body from the ventilation hole vertically and upwards, then horizontally passes the filtering layer and is communicated with the inner cavity of the ventilation plug body vertically and downward, so that water, dust and other impurities are effectively prevented from entering the bearing chamber; the filtering layer further prevents the dust and other small creatures from entering the bearing chamber, so that pollution to lubricants in the bearing chamber is avoided, and the replacement cycle of the lubricants and the service life of bearings are prolonged.
Description
Technical field
The utility model relates to breather plug, is specially the breather plug that a kind of water, dust and impurity are difficult for entering.
Background technique
Breather plug is widely used in the ventilation of the sealing components such as bearing chamber, existing breather plug, and simple in structure, with low cost, application is extensive.But there are two main problems: 1, the vent along continuous straight runs of breather plug passes into breather plug inner chamber, and water, dust and impurity easily enter breather plug, then enter vertically downward in the Seal cage of bearing chamber etc.2, there is no filtration, can not stop dust and other impurity to enter breather plug inner chamber.
Model utility content
The technical problem that the utility model solves is to provide a kind of breather plug, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of breather plug, comprise cock body, gag, filter layer, described cock body inside is provided with the inner chamber that vertically runs through vertically cock body, the bottom of described cock body is vertically fixed on the top of bearing chamber, cock body top seal is connected with described gag, between gag and cock body top end face, be pressed with described filter layer, cock body outer side surface has breach, cock body top end face has the vent that passes into vertically breach, and described filter layer is clipped between gag and cock body top end face the outlet of vent and cock body inner chamber is sealed.
Preferably, described gag is screwed in cock body top by screw thread.
Preferably, described filter layer adopts asbestos filter paper or sponge filter cloth, or adopts sponge filter cloth and the combination of asbestos filter paper overlaid.
Beneficial effect: the combined type breather plug that the utility model is related, air enters vertically upward through vent, then level is through filter layer, be communicated with breather plug inner chamber vertically downward again, can avoid water, dust and other foreign material to enter in bearing chamber, filter layer further stops dust and other little biology to enter in bearing chamber, avoids its pollution to the oiling agent in bearing chamber, extends the replacement cycle of wetting agent and the working life of bearing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of existing breather plug
Fig. 2 is the schematic diagram of the utility model preferred embodiment.
In figure: cock body 1, gag 2, filter layer 3, cock body inner chamber 4, vent 5, breach 6.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Schematic diagram referring to the existing breather plug of Fig. 1, the vent 5 of existing breather plug is level, therefore water and dust and other foreign material easily enter into bearing chamber inside, pollute bearing lubricant, and the replacement cycle shortening of oiling agent, the working life of bearing are reduced.
Schematic diagram referring to the utility model preferred embodiment of Fig. 2, a kind of breather plug, comprise cock body 1, gag 2, filter layer 3, cock body 1 inside is provided with the cock body inner chamber 4 that vertically runs through vertically cock body 1, the bottom of cock body 1 is vertically fixed on the top of bearing chamber, cock body 1 top is connected with gag 2 by thread seal, between gag 2 and cock body 1 top end face, be pressed with filter layer 3, cock body 1 outer side surface has breach 6, cock body 1 top end face has the vent 5 that passes into vertically breach 6, filter layer 3 is clipped between gag 2 and cock body 1 top end face the outlet of vent 5 and cock body inner chamber 4 is sealed.
In using process, air enters vent 5 through breach 6, because vent 5 is vertically upward, can avoid water and dust and other foreign material to enter bearing chamber inside by cock body inner chamber 4,3 of filter layers further stop dust and other little biology to enter in bearing chamber.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
