Description
Technical field
The utility model relates to the engine intake manifold device, especially relates to a kind of engine intake manifold port air-flow switching valve.
Background technique
At present, many engine intake manifolds have all been installed port air-flow switching valve in the air outlet, are used for controlling the gas rotating direction and the rotational speed that enter in the cylinder, improve mixed gas state in the cylinder, and are multiplex in the middle of direct injection diesel engine.The port air-flow switching valve that now uses adopts vacuum driver or electronic driver to drive, frequency of utilization is high, a lot of products are because design or selection are improper, have easy to wear, repair rate and repair again the shortcomings such as rate is higher, working life is short, have greatly reduced the usability of motor.
The model utility content
The purpose of this utility model is exactly to provide the engine intake manifold port air-flow switching valve that a kind of using scope is wide, the new energy of use is good, cost is low, safe and reliable for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of engine intake manifold port air-flow switching valve, this switching valve comprises live axle, valve block, coupling shaft and brake baffle, described live axle left end is connected with the driving mechanism of the change valve block angle of swing of outside, right-hand member connects four valve blocks successively by coupling shaft, is respectively equipped with brake baffle from the left end of two valve blocks of live axle away from.
The left end of described live axle is provided with ball joint, and live axle connects outside driving mechanism by ball joint, and driving mechanism is used for changing the valve block angle of swing.This ball joint adopts metallic material, has increased its intensity, wear resistance, and durability is better.
The sheathed connection steel ring of the right-hand member of described live axle has prevented the distortion in live axle and valve block left end joint, increases working life.
Described brake baffle is the baffle plate that prevents that valve block from contacting with housing when rotating, and reduces the wearing and tearing of valve block.
Described live axle and adjacent valve block are welded to connect by the polygonal projecting shaft.
Described driving mechanism is the vacuum driver.
By utilizing external drive mechanism to drive the rotation of valve block, the size control that utilizes the valve block angle of swing enters into gas rotating speed and sense of rotation in the cylinder from intake manifold, effectively improves the state of mixture, makes the running state of motor good.
The utility model has utilized the ball joint of the metallic material of live axle to increase wear resistance, utilizes steel ring to reinforce the distortion that prevents axle, and utilizing increases the wearing and tearing that brake baffle reduces valve block, makes the work that intake manifold can be stable.
Compared with prior art, the utlity model has following advantage:
(1) using scope is wide: valve block adopts the plastics of recoverable, and usability is good, and cost is low.
(2) safe and reliable: the live axle left end adopts metallic material with the outside ball joint that is connected, and wear resistance and durability are better; Live axle is equipped with steel ring, effectively prevents the distortion of live axle, increases working life, at the left end of valve block brake baffle is installed, prevented valve block when rotating with the contacting of housing, reduce wear.
