Ventilation cap

Abstract

The invention discloses a ventilation cap. The ventilation cap comprises a shell. An upper end cover and a lower end cover which are matched are arranged on the shell. A valve cavity is formed between the upper end cover and the lower end cover. A filter element is arranged in the valve cavity. The upper end cover is detachably connected with the lower end cover through a bolt sequentially penetrating the upper end cover and the lower end cover. In the assembling and use process of the ventilation cap, the upper end cover and the lower end cover can be flexibly disassembled through the bolt, and then the internal filter element can be directly replaced to meet the requirement for the filtering capacity of the ventilation cap under different working conditions; and after replacement is completed, it is only needed that the upper end cover and the lower end cover are assembled through the bolt again, the replacement process is simple, convenient and practicable, and the working condition adaptive capacity of the ventilation cap is effectively improved.

Description

technical field [0001] The invention relates to the technical field of gear reducers and gearbox supporting equipment, in particular to a vent cap. Background technique [0002] The breather cap is an important component widely used in mechanical equipment such as reducers and gearboxes. With the continuous improvement of use requirements, people have put forward higher requirements for the performance of the breather cap. [0003] At present, the more common vent caps in the mechanical field, although most of them can meet the basic needs of equipment exhaust and decompression, but due to the different filtering requirements under different working conditions in the actual working process, they are limited by the structure of the existing vent caps. , its single vent cap can only be assembled with one kind of filter element, if it is to adapt to different working conditions, it needs to replace the vent cap as a whole, which will undoubtedly increase the overall cost of pro...
