Description
Technical field
The utility model relates to a kind of vent line more particularly to a kind of engine breather pipe structures.
Background technique
During the work time, the high-pressure gas in combustion chamber can be from the gap between piston, piston ring and cylinder sleeve for engine
In scurry out to crankcase, cause crankcase pressure to rise.Therefore, these are usually carried to the crankcase waste gas of a large amount of oil gas,
It is passed through gs-oil separator, the machine oil after separation is back to oil sump, and the exhaust gas after separation leads to atmosphere via engine snorkel.
In existing technical solution, engine snorkel is only a simple equal diameter nylon tube.
Since gs-oil separator separation is limited, a part of machine oil is still carried in the exhaust gas after gs-oil separator separates, it is long
After phase work, machine oil can be gradually adhered to ventilation inside pipe wall, and form oil droplet drippage, both pollute environment, can also mislead client, will
Oil droplet is mistaken for engine oil leakage, seriously affects customer satisfaction.
In addition, forming oil film to prevent oil droplet drippage on the engine, cause fire, snorkel leads to atmospheric air (i.e. pipeline
Gas outlet) be usually placed in engine bottommost, it is exposed outside, lack protection.And northern China winter temperature is lower, high speed row
Che Shi, at the venting tube outlet for lacking protection, the air of low temperature has very high flow velocity with respect to snorkel, therefore has taken away big
The heat of amount causes temperature at venting tube outlet to drastically reduce, and then the moisture in exhaust gas gradually freezes here, final to block
Snorkel causes crankcase pressure to be substantially increased, and destroying engine, machine oil seals everywhere, so that lubricating oil leakage even engine report
It is useless.

Stating the extraneous one end of the second snorkel connection is outlet side；
The outlet side position of second snorkel is provided with multiple apertures, and the sheath includes fixed section and protection section, institute
It states sheath and is fixedly connected by fixed section with the second snorkel, the protection section of the sheath is by the outlet side of second snorkel
It is surrounded completely, and there are gaps between the protection section inner wall of the sheath and the outlet side outer wall of second snorkel.
Further, the fixed section of the sheath is straight pipe structure, and the protection section of the sheath is horn-like structure.
Further, the oil-collecting cup sidewall is provided with watch window, is equipped with transparent observation window at the watch window.
Further, the catchment cup two sides are respectively provided with convenient for hand-held recess.
The utility model has the advantage that compared with prior art
A kind of engine breather pipe structure provided by the utility model is applied as a kind of auxiliary tool in engine song
In ventilation system for shaft box, machine oil can be effectively prevented and form oil droplet drippage, avoids pollution environment and client complains.Meanwhile it ventilating
Sheath in pipe structure, it is possible to prevente effectively from the outlet side of the second snorkel is exposed, during preventing north of china in winter from running at high speed,
The Cryogenic air of high speed contacts the second snorkel and the second venting tube outlet is caused to freeze.

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.
Referring to Fig. 1 to Fig. 3, present embodiment discloses a kind of engine breather pipe structure, which connects oil gas
The gas outlet and the external world of separator, breather pipe structure include the first snorkel 1, cover 2, catchment cup 3, the second snorkel 4, sheath
5；
Removably lid is located at 3 top of catchment cup to cover 2, for sealing catchment cup 3, wherein in 2 bottom inside of cover is set
Screw thread is matched with the external screw thread at 3 top of catchment cup and is threadedly coupled.3 side wall of catchment cup is provided with watch window, watch window
Place is equipped with transparent observation window 3d, to facilitate machine oil liquid level in observation catchment cup 3.3 two sides of catchment cup are respectively provided with convenient for hand
The recess 3c held is installed to hold catchment cup 3, is safeguarded.Inlet suction port 2a and air outlet adapter 2b is equipped at the top of cover 2,
First inner chamber and second inner chamber, first inner chamber and air inlet connecting are independent by a vertical baffle 3a separation inside catchment cup 3
Head 2a is connected, and second inner chamber is connected with air outlet adapter 2b, and baffle 3a is equipped with multiple venthole 3b；
First snorkel, 1 one end is connected with the inlet suction port 2a of cover 2, the gas outlet phase of the other end and gs-oil separator
Connection, one end of the second snorkel 4 is connected with the air outlet adapter 2b of cover 2, other end connection is extraneous, and the second snorkel 4 connects
Leading to extraneous one end is outlet side；
The outlet side position of second snorkel 4 is provided with multiple aperture 4a, is used for tissue off-gas flows, can both shunt useless
Gas reduces flow velocity, and air-flow can be made uniform, prevents local eddy currents.Sheath 5 includes fixed section and protects section, sheath 5
Fixed section is straight pipe structure, and the protection section of sheath 5 is horn-like structure.Sheath 5 is fixed by fixed section and the second snorkel 4
Connection, between fixed section and the second snorkel 4 can by glue bond, or by welding, interference fit etc. other any ways into
Row is fixed, and the outlet side of the second snorkel 4 is surrounded by the protection section of sheath 5 completely, and the protection section inner wall of sheath 5 and the
There are gaps between the outlet side outer wall of two snorkels 4.
When using breather pipe structure provided in this embodiment, since the centrifugation of gs-oil separator is limited, through oil gas
Some machine oil is still carried in exhaust gas after separator separation, after long-term work, machine oil can be gradually adhered to the first snorkel 1
Inner wall, and oil film is formed, oil film is gathered in catchment cup 3 with gravity, it is therefore prevented that the oil droplet drippage external world pollutes and visitor
Complain at family.
Secondly, catchment cup 3 separates the oil gas further progress in exhaust gas.Baffle 3a with venthole 3b is logical to first
The off-gas flows that tracheae 1 introduces are reorganized, and flow velocity increases after exhaust gas passes through venthole 3b, and the tiny oil droplets in exhaust gas are hit
It hits in 3 inner wall of catchment cup, is gathered into oil film, separated and come out from exhaust gas.
Also, the present embodiment is provided with sheath 5 outside the outlet side of the second snorkel 4, can be ventilated with effective protection second
The outlet side of pipe 4 reduces Cryogenic air and heat exchange herein, it is therefore prevented that the generation of ice formation issues.
