Description

Technical Field

[0001] The utility model relates to the field of breathing valves, in particular to a breathing valve installed on an observation cover of a beam pumping unit reducer. Background Art

[0002] A breathing valve is a valve that can not only ensure that the tank space is isolated from the atmosphere within a certain pressure range, but also communicate with the atmosphere when the pressure exceeds or falls below this pressure range. When the breathing valve is used, during the process of exhaling and inhaling to the outside world, gas enters or exits from the airway, and dust in the outside air also enters the inside of the breathing valve;

[0003] A Chinese patent with publication number CN221569551U discloses a breathing valve, which relates to the technical field of breathing valves. The breathing valve includes a valve body, an airway is fixedly installed on the outside of the valve body, and a filter is arranged inside the airway. Each connecting mechanism includes a connecting plate, a limiting hole, a mounting plate, a connecting hole, a through hole and a screw. When cleaning the filter, the screw is turned to release the connection between the screw and the limiting hole through the limiting hole arranged on the outside of the connecting plate. At this time, the connecting plate is pressed downward to move the filter downward to release the connection between the filter and the airway. At this time, the filter is disassembled and can be cleaned. After cleaning, the connecting plate is clamped to the inside of the connecting hole. At this time, the filter enters the inside of the airway. At this time, the screw is turned to enter the inside of the limiting hole. At this time, the connecting plate is fixed to the inside of the connecting hole. At this time, the filter is installed. The detachable filter facilitates the staff to clean and repair the filter.

[0004] When the breathing valve of the above patent is installed on a device in actual use, if the diameter of the installation position of the breathing valve is different from the diameter of the connecting port of the installed device, it is necessary to replace the breathing valve with a different size of connecting port, which limits the installation of the breathing valve.
