One rotates with the rocker arm that valve block shaft is connected, and then realizes the closing of braking valve block, when compressed air pressure unloads in manipulation cylinder
It goes, braking valve block is realized under engine back pressure effect to be resetted, and band moving valve plate shaft rotates in turn, and then pushes rocker arm
Rotation, and realize the reset of piston push rod；Manipulation cylinder tail portion is fixed on manipulation cylinder support plate by removable pin, whole process,
Manipulation cylinder can constantly deflect as the change of working condition is by the component along rocker arm axis direction.
The main failure of current exhaust brake valve is manipulation cylinder hair fastener, piston eccentric wear, manipulation cylinder gas leakage, piston O-ring mill
The reasons such as damage, auxiliary connection looseness, these failures are largely and the stress shape of current most of exhaust brake valve operating mechanisms
State is related.Current many exhaust brake valve manipulations cylinder tail portion is hinged with bracket, and piston push rod is hinged with rocker arm, and point of interface is opposite to be transported
Dynamic excessive, reliability substantially reduces；All kinematic pairs are fully exposed in external environment, and the external environments factor such as dust, steam all adds
The failure of acute kinematic pair；In the case of the push rod of cantilever beam structure is by larger vibration in the course of work, auxiliary connection loosening, each component
The failures such as abrasion further deteriorate；Further, since the presence of rocker arm to manipulate cylinder push rod opening or closing in execution valve block
When, suffered power is not overlapped with piston push rod axis, and there are transverse components, it is be easy to cause piston or piston O-ring eccentric wear, into
And causes to manipulate cylinder gas leakage and manipulate the failures such as cylinder hair fastener.
