Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model single unit system.
Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited
In following embodiments.
As shown in Figure 1, a kind of rotary-type air valve bar diesel engine spiracle Oil sealing assembly, including valve bar assembly, the spring seat of honour
2 and valve oil seal 7, the valve bar assembly includes valve stem 1 and valve sealing head 101, one end of the valve stem 1 from
It is set gradually under above there are three annular groove, the other end of valve stem 1 is fixedly connected with valve sealing head 101, and the annular is sliding
Slot, which is connected together, the valve collet 201 of cooperation, and valve collet 201 is fixedly connected with the spring seat of honour 2, and the spring seat of honour 2 is arranged
There is valve spring 3, the bottom of valve spring 3 is provided with spring lower seat 4, and valve spring 3 is located at the spring seat of honour 2 and spring lower seat 4
Between, and the end part don't push pressing spring seat of honour 2 at 3 both ends of valve spring and spring lower seat 4, the spring lower seat 4 and valve oil
Envelope 7 is integrally formed, and the valve stem 1 slidably connects valve guide bushing 5, and one end of valve guide bushing 5 is located in valve oil seal 7, gas
The other end of door conduit 5 is located at outside valve oil seal 7, and the end of described 1 one end of valve stem sequentially passes through valve guide bushing 5, valve oil
After envelope 7, it is located at outside valve oil seal 7.
Wherein, the valve bar assembly is provided with radiator structure 6.
Wherein, the radiator structure 6 includes multiple spherical accommodating cavities 601 and liquid storage cavity 602, and the spherical receiving is empty
Chamber 601 is located in valve stem 1, and liquid storage cavity 602 is located in valve sealing head 101, between the spherical shape accommodating cavity 601 successively
After connection, it is connected to liquid storage cavity 602.
Wherein, it is connected between the spherical accommodating cavity 601 and liquid storage cavity 602 by drain lumen 603.
Wherein, the number of the spherical accommodating cavity 601 is 3-5, and the number of liquid storage cavity 602 is 1-3.
Wherein, the valve collet 201 is equipped with the lock tongue 2011 cooperated with annular groove.
Wherein, the valve oil seal 7 includes oil tight skeleton outer layer and rubber inner layer, the rubber inner layer and oil tight skeleton
Outer layer is integrally formed.
Working principle: valve stem 1 moves back and forth, because of valve under the driving of valve Power Component relative to valve guide bushing 5
Bar 1 is fixed by valve collet 201, and therefore, the spring seat of honour 2 squeezes valve spring 3 relative to 1 back and forth movement of valve stem,
Valve spring 3 squeezes spring lower seat 4.Because spring lower seat 4 and valve oil seal 7 are integrally formed, therefore, valve oil seal 7 is relative to gas
Door rod 1 moves back and forth.
During valve stem 1 moves back and forth, when 1 discontinuity of valve stem, valve stem 1 rotates, specifically
It is the lock tongue 2011 on valve collet 201 relative to the annular groove generation relative circumferential sliding on valve stem 1.Pass through valve stem
The uneven stress of valve stem 1 is alleviated in 1 rotation, and then prevents the local body of rod of valve stem 1 position, because rubbing with valve guide bushing 5
It is excessive, it causes local damage excessive, influences the uniformity on 1 surface of valve stem, when sliding valve stem 1 and valve guide bushing 5 relatively,
No longer full cooperation, reduces service life.
