Between the first sealing ring 3,
The air valve includes air valve ontology 2 and the first sealing ring 3, the air valve ontology 1 be applied in 1 top of upper cover ontology and
It is arranged on the stomata 1-3；
First sealing ring 3 is radial close for making to be formed between air valve 2 and stomata 1-3 between air valve ontology 2 and stomata 1-3
Envelope.
The lower part of the air valve ontology 2 is provided with first external screw thread 2- compatible with the internal screw thread 1-6 of the stomata 1-3
1；Stomata 1-3 is gentle, and valve body 2 is connected through a screw thread.
The inner surface of 1 top surface of upper cover ontology is provided with spring 4, and the spring 4 is located at the periphery of stomata 1-3.It is described
Spring 4 is set to the center of 1 inner tip of upper cover ontology, is attached with upper cover ontology 1 using interference fit.Spring 4
Upper end connect with the inner surface of upper cover ontology 1.The spring 4 is set to 1 inner tip center of upper cover ontology, with upper cover
Ontology 1 is attached using interference fit, can be removed jointly with upper cover ontology 1 when replacing filter core, and secondary assembly is avoided to ask
Topic.Its 4 lower end of spring is fixed with filter core, can effectively limit filter core axial motion.
Further, the upper cover ontology 1 is transparent cylindrical shell structure.The material of the upper cover ontology 1 is TPU.
In use, 1 internal core stopping state of upper cover ontology can intuitively be observed by transparent upper cover ontology 1, solves filter core
It maintains the adverse effect generated to oil supply system not in time because of blocking, ensure that the normal work of oil supply system to the full extent
Make.
Further, it is provided on the upper cover ontology 1 one week and fluted 1-5 is set on flange 1-4, the flange 1-4,
The groove 1-5 is located at the lower part of flange 1-4.The second external screw thread 1-7, the second outer spiral shell are provided on the upper cover ontology 1
