the valve core 8 is internally provided with a gas channel 801 and a valve rod channel which is convenient for the valve rod to operate, and the gas channel 801 is uniformly distributed on the outer side of the valve rod 5 and is axially parallel to the axis of the valve core 8;
the valve rod 5 axially moves along the valve core 8 on the valve core 8 through a valve rod 5 channel, the valve rod 5 comprises a connecting part 501 and a blocking part 502 integrally formed with the connecting part 501, and the blocking part 502 is contacted with the valve body 2 at the second end 202 to form a linear sealing structure 6; the spring 4 is mounted on the outer ring of the connecting portion 501 of the valve rod 5.
It should be further noted that the connection portion 501 of the valve stem 5 runs axially in the passage of the valve stem 5.
It should be further noted that the inner diameter of the first hole is the same as the sliding channel 9.
It should be further noted that the second hole has a smaller diameter than the sliding channel 9, and a first boss 203 is formed between the sliding channel 9 and the second hole.
It should be further noted that the side surface of the end cap 502 of the valve stem 5 is a slope, and the edge of the first boss 203 is in pressure contact with the slope of the end cap 502 to form the wire sealing structure 6. Specifically, after the gas is exhausted, the valve rod 5 and the end sealing part 502 of the valve body 2 automatically form a linear sealing structure 6 by means of initial impact, so that the exhaust valve can be closed in time and is not easy to leak.
The outer side surface of the valve rod 5 connecting portion 501 is provided with a spring seat 3 having a stopper function for the spring 4. The limiting action can accurately control the force of the spring 4 and the stroke of the valve rod 5 through limiting, so that the lift of the exhaust valve can be adjusted, the accuracy of the lift of the exhaust valve can be accurately ensured, the overstress impact of the valve rod 5 and the spring seat 3 is avoided, and the service life of the exhaust valve is prolonged.
