Whole process is divided into three phases: induction stroke stage, high pressure expansion stage, exhaust stroke stage.The air inlet of induction stroke stage
Door is opened, and is filled with high pressure gas and is pushed piston downlink, valve-closing after the completion of air inlet, high pressure gas expansion workmanship continues to press on work
Downlink is filled in, exhaust stroke graduated discharge door is opened, and IC Intake Valve Closes, piston stroking upward releases residual pressure after the completion of workmanship
It puts.
Whole process is mainly controlled by the air distribution system of engine, and valve assembly device is it in air distribution system
Core component realizes the breathing action of cylinder by the opening and closing of control valve assembly.Traditional air motor distribution
Cheng Zhong, under high pressure working environment, the valve disc work conical surface is influenced by higher back pressure, is easily mutually separated and is sent out with the valve seat conical surface
Angry body leakage, valve are influenced by biggish back pressure, will lead to initial tension of spring and be insufficiently resistant to higher gas pressure, make gas
It is also easy to be developed angry body leakage by high-pressure jack under door closure state, causes engine air consumption to increase, secondly, valve stem and valve
It is excessive to cover gap, by the frequent impact of high pressure gas in valve assembly scavenging period, is easy to produce between valve stem and valve pocket
A series of problems, such as raw shaking, causes air distribution system air-tightness to decline, overall power and low efficiency.
Therefore, a kind of Novel valve assembly apparatus is designed, high pressure gas leakage amount is reduced, is to improve air motor work
The important measure of efficiency.
