Abstract
The utility model discloses a one-way valve for an oil return port of an oil-gas separator, which comprises an oil return port cavity body (1), an oil return joint (2) and a cone piston (3). The oil return joint (2) consists of a hollow pipe (21) and a connecting disk (22) with a center hole. The oil return joint (2) is connected at the lower end of the oil return port cavity body (1). The disk surface of the connecting disk (22) with the center hole is internally provided with a plurality of radial convex ribs (23). The cone piston (3) is arranged in the oil return port cavity body (1). The one-way valve for the oil return port of the oil-gas separator has the advantage of preventing mixed gas discharged by a power machine from entering the separator from the oil return port of the separator so as to guarantee that a gas inlet channel, a gas outlet channel and an oil outlet channel of the separator perform respective functions without causing confusion and improve oil-gas separation effect of the separator.
Description
Technical field:
The utility model relates to a kind of oily gentle deaerator that separates with mixed gas, specifically is a kind of one-way valve of deaerator return opening.
Background technique:
The proposition of innovation-oriented country's strategy, the Chinese government requires the fuel of dynamic power machine to be fully burned, with discharge of harmful gases such as minimizing carbon monoxide to environmental protection and energy-conservation very attention.For the requirement that makes energy-saving and emission-reduction is fulfilled, the vapour of the existing automotive gasoline engine of China or diesel engine and other types, deaerator generally all is installed on the diesel engine, existing deaerator mainly is by cavity body, filter core, mixed gas inlet, the air outlet, return opening is formed, its mounting type generally all is the mixed gas exhaust port that the mixed gas inlet of deaerator inserts dynamic power machine, filtration through deaerator, gas after the separation is discharged from the air outlet of separator, and the oil plant after the separation is back to continuation use in the dynamic power machine from the return opening of separator.As, the air outlet hole of the mixed gas intake interface on the deaerator of diesel engine of vehicle and the cylinder head of diesel engine is connected, the air outlet of separator is connected by the suction tude of external application adapter and diesel engine, the return opening of separator is communicated with the crankcase of diesel engine, the mixed gas that ejects in the diesel engine of vehicle crankcase separates through separator, separate back gas and return the suction tude of diesel engine, and the machine oil after separating continues the bent axle lubricate in the return opening of separator backflows the crankcase of diesel engine.From this annexation, the big portion of the mixed gas of diesel engine crankcase is that the suction port from separator enters separator, but mixed gas that also might the diesel engine crankcase enters in the separator from the return opening of separator, this just must have influence on the oil gas separation of separator, this illustrates that existing deaerator structurally also deposits certain defective, is necessary to be improved and improve.
The model utility content:
The technical problems to be solved in the utility model is, at the defective that above-mentioned prior art exists, provides a kind of mixed gas that dynamic power machine discharges enters the defective of separator from the return opening of separator one-way valve of deaerator return opening that overcomes.
Technical solution of the present utility model is that a kind of one-way valve with deaerator return opening of following structure is provided.
A kind of one-way valve of deaerator return opening, be characterized in, comprise return opening cavity body, back leakage connection and taper piston, back leakage connection is by hollow tubular and have the center hole land and form, back leakage connection is connected the lower end of return opening cavity body, have in the card of center hole land and be provided with several radially convex tendons, taper piston is arranged in the return opening cavity body.
After adopting above structure, compared with prior art, the utlity model has following advantage: mainly be to prevent that the mixed gas that dynamic power machine is discharged from entering in the separator from the return opening from separator, with the air inlet that ensures separator, give vent to anger, fuel-displaced passage " Each performs its own functions " and confusion can not take place, to improve the oil gas separation of separator; Being provided with several radially convex tendons in the card that has the center hole land, mainly is the drainback passage that makes on the back leakage connection of taper piston bottom surface, and the oil plant after the separation can successfully be back in the dynamic power machine.
As improvement, the inwall of described return opening cavity body is set to conical surface body, and described conical surface wall is provided with several axial convex tendons.This structure, mainly be that the oil plant after the separation can be flowed in the dynamic power machine along the internal face and the convex tendon of oil return cavity, and conical surface body is set, when the mixed gas in the dynamic power machine when the return opening of separator enters separator, the up mantle body piston stroking upward of trying hard to recommend of mixed gas, the small end of taper piston can be matched with the upper end-hole of oil return cavity, enter in the separator from return opening thereby block mixed gas.
Description of drawings:
Accompanying drawing is the one-way valve structures schematic representation of the utility model deaerator return opening.
Shown in the figure: 1, return opening cavity body, 2, back leakage connection, 21, hollow tubular, 22, have a center hole land, 23, convex tendon radially, 3, taper piston.
Embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Shown in the accompanying drawing, a kind of one-way valve of deaerator return opening, comprise return opening cavity body 1, back leakage connection 2 and taper piston 3, back leakage connection 2 is by hollow tubular 21 and have center hole land 22 and form, back leakage connection 2 is connected the lower end of return opening cavity body 1, have in the card of center hole land 22 and be provided with several radially convex tendons 23, taper piston 3 is arranged in the return opening cavity body 1.
As further improvement, the inwall of return opening cavity body 1 is set to conical surface body, and conical surface wall is provided with several axial convex tendons (accompanying drawing does not show).
Claims (2)
1. the one-way valve of a deaerator return opening, it is characterized in that: comprise return opening cavity body (1), back leakage connection (2) and taper piston (3), described back leakage connection (2) is by hollow tubular (21) and have center hole land (22) and form, described back leakage connection (2) is connected the lower end of described return opening cavity body (1), be provided with several radially convex tendons (23) in the described card that has center hole land (22), described taper piston (3) is arranged in the return opening cavity body (1).
