Description

A kind of blind flange component

Technical field

The utility model is related to a kind of blind flange components.

Background technology

Due to, there are gap, always thering is sub-fraction exhaust gas to enter crankcase by combustion chamber between engine piston and cylinder sleeve, Combustion gas is inevitably scurried into inside cylinder head cover in cylinder, need to be by crankcase and atmosphere to ensure that crankcase pressure is stablized； The 70% of these exhaust gas (gas blowby) is the hydrocarbon (HC) not burnt, these exhaust gas can water down, deteriorate machine oil, and also Engine parts can be corroded；Particularly at high speed, serious gas blowby but will cause the scarce machine oil between piston ring and cylinder block Phenomenon；In the engine of a variety of series, simply oil return hole, part crankcase gas blowby are offered on cylinder head cover Oil-gas Separation cover board Oil-gas Separation chamber interior just is not entered directly into from the oil return hole opened up by split tunnel, is then exhausted directly to air In, due to not passing through Oil-gas Separation passage, this part gas blowby contains a large amount of machine oil, pollutes the environment and can cause engine machine The increase of oil consumption, user must not infrequently supplement machine oil, and engine maintenance cost is caused to increase.

Utility model content

To solve the above problems, the utility model proposes a kind of blind flange component, good oil gas separation effects.

A kind of blind flange component of the utility model, including cover board body, the first oil-collecting groove, the second oil-collecting groove, Ventilation mesh, baffle, the first oil return pipe cap, the first oil return pipe, the second oil return pipe cap, the second oil return pipe, sealed interface, installation Hole；The ventilation mesh of meshy arrangement is distributed on the cover board body；Baffle is arranged on above ventilation mesh and and cover board body Place planar shaped has a certain degree；First oil return pipe is fixedly mounted on the bottom of the first oil-collecting groove；Described second time Oil pipe is mounted on the bottom of the second oil-collecting groove by sealed interface；The first oil return pipe cap and the second oil return pipe cap are pacified respectively Mounted in the first oil return pipe and the second oil return bottom of the tube.

Further, the cover board body uses integrally stretching moulding process；The first oil-collecting groove and are designed with thereon Two oil-collecting grooves, shape are terraced row.

Further, second oil return pipe is designed as double 90 degree of warp architecture shapes.

Further, the first oil return pipe cap and the second oil return pipe cap are U-shaped or so spaced-apart type oil return pipe cap.

Compared with the prior art, the utility model has the following beneficial effects：A kind of novel cover of the utility model Plate component, versatile and machine oil and exhaust gas can be efficiently separated, oil return significant effect；Substantially reduce exhaust pollution.

Specific embodiment

A kind of blind flange component as shown in Figure 1 and Figure 2, including cover board body 1, the first oil-collecting groove 2, the second oil-collecting Groove 3, ventilation mesh 4, baffle 5, the first oil return pipe cap 6, it is the first oil return pipe 7, the second oil return pipe cap 8, the second oil return pipe 9, close Sealing-in mouth 10, mounting hole 11；The ventilation mesh 4 of meshy arrangement is distributed on the cover board body 1；Baffle 5 is arranged on ventilation net It has a certain degree above hole 4 and with 1 place planar shaped of cover board body；First oil return pipe 7 is fixedly mounted on the first oil-collecting The bottom of groove 2；Second oil return pipe 9 is mounted on the bottom of the second oil-collecting groove 3 by sealed interface 10；Described first time 6 and second oil return pipe cap 8 of oil pipe cap is separately mounted to 9 bottom of the first oil return pipe 7 and the second oil return pipe.

Wherein, the cover board body 1 uses integrally stretching moulding process；The first oil-collecting groove 2 and second is designed with thereon Oil-collecting groove 3, shape are trapezoidal；Second oil return pipe 9 is designed as double 90 degree of warp architecture shapes；The first oil return pipe cap 6 and second oil return pipe cap 8 be U-shaped or so spaced-apart type oil return pipe cap.

A kind of blind flange component of the utility model, versatile and machine oil and exhaust gas can be efficiently separated, oil return effect Fruit is notable；Substantially reduce exhaust pollution.

Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality New spirit and scope are defined, without departing from the design concept of the present utility model, ordinary people in the field couple The all variations and modifications that the technical solution of the utility model is made, should fall within the protection scope of the present utility model, this reality With new claimed technology contents, all record in detail in the claims.
