Abstract
The utility model discloses an air valve rod seal sleeve for a natural gas engine. The air valve rod seal sleeve comprises a round bucket sleeve body, wherein both two ends of the round bucket sleeve body are provided with open mouths, a seal lip is mounted at one open mouth of the round bucket sleeve body, both two ends of the seal lip are provided with open mouths, and the other open mouth end of the round bucket sleeve body is provided with a skirt part which extends outward in the radial direction. The air valve rod seal sleeve for a natural gas engine is advantaged by convenient installation, effectively lowered engine oil consumption of the engine, and prolonged service life of the engine.
Description
Technical field
The utility model relates to the natural gas engine technical field, especially relates to a kind of used for natural gas engine valve stem stuffing box gland.
Background technique
The effect of valve group is to be responsible for inputting fuel and combustion gas in motor, valve stem and air valve rod seal cover are the important component parts of valve group, the sealing lip of natural gas engine valve stem stuffing box gland of the prior art is pine too, can not effectively prevent leakage of oil; The valve stem stuffing box gland does not have the skirt section, and difficulty is installed, and installs and deviation easily occurs, causes engine motor oil to consume high.
The model utility content
Technical problem to be solved in the utility model is: a kind of used for natural gas engine valve stem stuffing box gland is provided, and easy for installation, effectively reduce engine motor oil consumption, prolonged service life of aeroengine.
For solving the problems of the technologies described above, the technical solution of the utility model is: used for natural gas engine valve stem stuffing box gland, comprise, the drum body of open at both ends, a uncovered sealing lip that is equipped with of described drum body, the open at both ends of described sealing lip, another open-mouth end of described drum body is provided with the skirt section that extends radially outward.
Preferably, described sealing lip outer circumferential face is provided with toroidal cavity, in the described toroidal cavity annular elastomeric is installed.
Preferably, described sealing lip inwall is provided with some annular ridges, and the gyration center of described annular ridge is consistent with the gyration center of described sealing lip.
Adopted technique scheme, the beneficial effects of the utility model are: owing to having designed above-mentioned used for natural gas engine valve stem stuffing box gland, another open-mouth end at the drum body is provided with the skirt section that extends radially outward, easy for installation, and can prevent from installing and deviation occur, use this valve stem stuffing box gland can effectively reduce engine motor oil consumption, increasing service life of engine.
Because the sealing lip outer circumferential face is provided with toroidal cavity, annular elastomeric is installed in the toroidal cavity, effective frizing, thus effectively reduce engine motor oil consumption, increasing service life of engine.
Description of drawings
Accompanying drawing is the utility model embodiment's structural representation;
Wherein: 1, drum body; 2, sealing lip; 3, skirt section; 4, annular spring; 21, toroidal cavity; 22, annular ridge.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in drawings, used for natural gas engine valve stem stuffing box gland comprises, the drum body 1 of open at both ends, a uncovered sealing lip 2 that is equipped with of drum body 1, the open at both ends of sealing lip 2, another open-mouth end of drum body 1 is provided with the skirt section 3 that extends radially outward.Sealing lip 2 outer circumferential faces are provided with toroidal cavity 21, in the toroidal cavity 21 annular elastomeric are installed, and in the present embodiment, annular elastomeric adopts annular spring 4, effectively frizing.Sealing lip 2 inwalls are provided with some annular ridges 22, and the gyration center of annular ridge 22 is consistent with the gyration center of sealing lip 2.This valve stem stuffing box gland is easy for installation, and can prevent that deviation from appearring in installation, uses this valve stem stuffing box gland can effectively reduce engine motor oil consumption, increasing service life of engine.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
