Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, and without with limiting the utility model.
As shown in Figure 1 to Figure 3, a kind of use for diesel engine respirator, including respirator body 1 and respirator upper casing 2, respirator
Upper casing 2 is arranged on the top of respirator body 1, and respirator body 1 fits together to form respirator receiving sky with respirator upper casing 2
Between；
Respirator upper casing 2 is equipped with gas outlet 3, is equipped with ventilation valve module 4 in respirator accommodation space and labyrinth 5, labyrinth 5 are set
In 4 lower section of ventilation valve module, ventilation valve module 4 includes ventilation valve catch 6, ventilation valve spring leaf 7 and ventilation valve bottom plate 8, divulges information
Valve spring piece 7 and ventilation valve catch 6 are fixed on the upper surface of ventilation valve bottom plate 8, and ventilation valve spring leaf 7 is located at ventilation valve bottom plate 8
Close to the side of respirator upper casing 2, the connecting shaft in the lower surface connection labyrinth 5 of ventilation valve bottom plate 8, specifically, the connecting shaft
For eccentric shaft, the position of 8 face ventilation valve spring leaf 7 of ventilation valve bottom plate is equipped with the intercommunicating pore of both sides above and below connection ventilation valve bottom plate
9, specifically, the upper side and lower side of ventilation valve bottom plate 8 refers to side where ventilation valve plate upper surface and lower surface, ventilation valve respectively
The edge of bottom plate 8 is in contact with the inner wall of respirator body 1, and sealing ring is equipped between ventilation valve bottom plate 8 and respirator body 1
10。
The utility model is designed with effect by special ventilation valve module and solves the problems, such as Diesel Engine Breather oil leak.
Specifically, ventilation valve spring leaf 7 be arranged between ventilation valve catch 6 and ventilation valve bottom plate 8, i.e., ventilation valve catch 6, lead to
Air valve spring piece 7, ventilation valve bottom plate 8 are sequentially distributed from top to bottom, specifically, being in 15 between ventilation valve catch and ventilation valve bottom plate
Degree or 30 degree of angles, ventilation valve spring leaf effectively limit ventilation valve spring leaf between ventilation valve catch and ventilation valve bottom plate
