Description
Technical field
The invention belongs to gs-oil separator technical fields, are related to a kind of fine seperator of integrated bypass valve.
Background technology
At present, for the engine bonnet of integrated gs-oil separator, fine seperator blocks in order to prevent or engine is altered
Tolerance increases and causes system pressure excessively high, it will usually by-passing valve be set to carry out pressure release to separator system.However, in by-passing valve
When opening pressure release, engine blow-by gas directly enters the gas handling system of engine without separation by the by-passing valve of unlatching, can be right
Engine generates many adverse effects, such as：Consumption of lubricating oil is too fast, machine oil enters gas handling system and reduces the property of turbocharger
Energy, gas blowby are directly discharged into air and pollute environment etc..
Therefore, when designing engine bonnet, it will usually by-passing valve is arranged between preseparator and fine seperator, when
Engine is because when air leak amount is excessive or fine seperator blocking makes crankcase pressure excessively high, by-passing valve is opened, and gas blowby first passes through pre-
After the pre-separation of separator, then through by-passing valve enter gas handling system, i.e., by-passing valve only bypasses fine seperator, can so make pre-
Separator is pre-separated out the bulky grain machine oil included in gas blowby, reduces the adverse effect to engine.However, with engine
The propulsion of lightweight trend, current engine structure is compacter, is capable of providing the sky that each functional unit is integrated to the cover
Between it is fewer and fewer, this there have been situation about can not be arranged on by-passing valve between preseparator and fine seperator, and can only will
By-passing valve is arranged on bypass, and when by-passing valve is opened, preseparator and fine seperator will be bypassed simultaneously, so as to gas blowby occur
The situation of gas handling system is directly entered without separation, and then is had a negative impact to engine.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind can be only to essence point
Fine seperator from the integrated bypass valve that device is bypassed.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of fine seperator of integrated bypass valve, the fine seperator include housing, the refined filtration unit of setting inside housings
And the bypass block on refined filtration unit is arranged on, one end of the housing offers gas outlet, the refined filtration unit bag
Upper end cover, bottom end cover and the filter paper being arranged between upper end cover and bottom end cover being oppositely arranged inside housings are included, it is described
Air inlet is offered on bottom end cover, the bypass block includes the mobile valve body being arranged on upper end cover and is arranged on valve body
Resetting spring between upper end cover, the refined filtration unit move up and down carry out pressure release by valve body.
The bypass block is integrated in the inside of fine seperator, and bypass block is made to play the role of by-passing valve, and realizing will
By-passing valve is integrated on fine seperator.
The gas outlet is opened in the lower part of housing.The housing is integrated in the cover of engine, and described goes out
Gas port is connected with the gas handling system of engine.
The filter paper is tubular filter paper, and the inside of the tubular filter paper is inlet chamber, which is connected with air inlet,
The outside of the tubular filter paper is outlet chamber, which is connected with gas outlet.
Through hole is offered on the upper end cover, the valve body is arranged on by through hole movement on upper end cover.Described
Through hole is connected respectively with inlet chamber, outlet chamber.
The valve body includes the cover board, through-Penetration portion and the spring coupling part that are sequentially connected from top to bottom, and the cover board is set
Put on the top of upper end cover, the through-Penetration portion through being arranged on upper end cover, the both ends of the resetting spring respectively with it is upper
End cap, spring coupling part are connected.The resetting spring in compressive state, makes cover board be compressed tightly against the upper of upper end cover always
Surface.The through-Penetration portion passes through through hole, and cover board and spring coupling part are linked together.
The spring coupling part is to be arranged on through-Penetration portion lower end and outwardly flange, and the resetting spring card is set
Between upper end cover and flange.
The distance between the upper end cover and shell top wall are less than the height of through-Penetration portion.When cover board moves up, shell
Body upper wall can be used as top dead centre, carry out /V to cover board, prevent that cover board displacement distance is excessive, resetting spring compression degree mistake
Greatly, excessive pressure is generated to spring coupling part, and spring coupling part is damaged.
Upper sealing ring is equipped between the cover board and upper end cover.
The inlet chamber is internally provided with central tube, the central tube respectively with air inlet, filter paper and cover board lower surface phase
Connection.
Lower seal is equipped at the air inlet.
The present invention is separated in practical application, after the pre-separated device pre-separation of gas blowby that engine generates when working by essence
The air inlet of device enters central tube, becomes clean gas after filter paper filters, and enters in outlet chamber, is arranged afterwards by gas outlet
Go out, filter paper intercepts the machine oil contained in gas blowby and other liquid particles.When air leak amount is excessive or filter paper blocking causes center
During gas blowby hypertonia in pipe, gas blowby promotes cover board to move up, and gas blowby via through holes enter outlet chamber, and after filter paper filters
Clean gas discharged together by gas outlet, realize pressure release.
Compared with prior art, the invention has the characteristics that：
1) it is compact-sized, bypass block is integrated in the inside of fine seperator, can not only realize only to fine seperator into
The purpose of row bypass, improves the separative efficiency of entire piece-rate system, avoids the unfavorable shadow that engine blow-by gas generates engine
It rings, while greatly reduces bypass block the space occupied, suitable for engine structure further compact at present；
2) function of sealing and pressure release during high pressure, simple in structure, repair and replacement side when bypass block can realize low pressure
Just, /V and by shell top wall to cover board is carried out, can effectively prevent the pressure of engine blow-by gas from increasing suddenly to pop up valve body
Refined filtration unit, thus stability in use is good.
