Description
Technical field
The utility model is related to a kind of special small open piston ring of natural gas engine.
Background technology
Piston ring is an important spare part of engine movements system, particularly natural gas engine, and ignition temperature is more
Height, working condition is more severe, has 70~80% to be transmitted to casing wall by piston ring and dissipate in the heat suffered by piston top, living
The effect of plug ring is to ensure the sealing between piston and cylinder, and is worked under conditions of high temperature, high pressure, high speed and lubricating difficulties
's.Under the conditions of thermal expansion, due to technology, piston ring has a certain size opened gap.As long as piston ring
It is not stuck operationally, it is desirable to which the opened gap of piston ring is the smaller the better, such gas sealing is good, does not allow the gas of combustion chamber
Crankcase is drained to, the leakage rate of gas is controlled, in bottom line, to improve the thermal efficiency, gas leakage can also make under the power of engine
Drop, and machine oil is rotten fast, and piston ring can also play knife-type oil stripping action, and lubricating oil unnecessary on cylinder wall is scraped, while make again
A thin layer of oil film is furnished with casing wall, it is ensured that piston ring, piston, the normal lubrication of cylinder, it also has conductive force, passes through work
The heat of piston is conducted to cylinder sleeve by plug ring, is finally supporting role, and piston is kept in the cylinder, to prevent piston and cylinder wall
Directly contact, reduce frictional resistance, and prevent engine knock.
The content of the invention
Technical problem to be solved in the utility model is that the high natural gas engine of a kind of good airproof performance, structural strength is special
Use small open piston ring.
The utility model is achieved through the following technical solutions：A kind of special small opening piston of natural gas engine
Ring, including ring body, ring body is provided with an opening, and the length of opening is 0.40~0.50mm, and the two ends of the ring body are equipped with one
Projection；A connection piece is connected between the projection；Connector surface two ends are equipped with a recess；The recess surface is set
There is screw thread, recess is connected through a screw thread an annulus；Surface of the ring body at projection is provided with screw thread.
As preferred technical scheme, the shape of the connector and the shape of opening match, length and Opening length
It is identical；A through hole is provided with inside the connector；The diameter of the through hole is identical with the diameter of projection, and through-hole wall is provided with sealing
Rubber layer.
As preferred technical scheme, the caulking gum layer is made of silicon boron rubber.
As preferred technical scheme, the diameter of any one recess bottom surface length corresponding thereto between face and ring body
It is identical.
As preferred technical scheme, the length of the screw thread is the 1/7 to 1/8 of ring body total length.
The beneficial effects of the utility model are：The utility model is simple in construction, and the structural strength of piston ring is high；Piston ring connects
Head is easy to docking, can effectively reduce abrasion；With good thermal conductivity and sealing.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structure sectional view of the present utility model.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive

State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, a kind of special small open piston ring of natural gas engine, including ring body 1, ring body 1 is opened provided with one
Mouthful, the length of opening is 0.40~0.50mm, test proves that, the opening of this length, sealing, frizing effect is more preferable,
Conduct thermal effect also more preferable than original ring.Deformation is reduced, changes engine overall performance.Through experiment card high efficiency, oil saving, improve
Service life, improves exhaust emissions.
In the present embodiment, the two ends of ring body 1 are equipped with a projection 2；A connection piece 3 is connected between the projection 2.
Further, the shape of connector 3 and the shape of opening match, and length is identical so that whole during connection connector
Body structure is also a circle.
Further, the inside of connector 3 is provided with a through hole；The diameter of the through hole is identical with the diameter of projection 2, projection 2
Insert through hole so that ring body is connected with connector, through-hole wall adds sealing provided with caulking gum layer 4.
Further, caulking gum layer 4 is made of silicon boron rubber, can high temperature resistant.
In the present embodiment, the surface two ends of connector 3 are equipped with a recess 5；The surface of recess 5 is provided with screw thread, recessed
Portion 5 is connected through a screw thread an annulus 6；Surface of the ring body 6 at projection 2 is provided with screw thread so that annulus 6 can be in ring
Move, be conveniently adjusted on body and recess, annulus 6 can be moved to the junction of ring body 1 and connector 3, further increase close
Envelope is acted on and structural strength.
Further, length of any one bottom surface of recess 5 corresponding thereto between face is identical with the diameter of ring body 1, is easy to make company
Fitting 3 and ring body 1 match so that ring body 1 and being threaded through for recess 5 connect into a circular arc, are easy to the movement of annulus 6.
