Pressure and the reachable 20bar of pressure differential maximum of second stage air pressure, and skilled person will appreciate that, 20bar
For quite huge draught head away from, thus, commonly use in structure technology and practical application, tend to carry
Valve port is inputted because of the imbalance of its external and internal pressure difference for the air pressure of first stage air pressure or second stage air pressure
Failure and the damage of valve are produced, and then, when overall two-stage air pressure input framework is practically applied to plastics
When among bottle production line, when wherein one input valve port breaks down or damaged, then it must stop production line
And respectively test and repair for each input valve port, to confirm being which valve port produces problem
Afterwards, replacement of element or reinforcement can be just carried out, in this way, the prouctiveness of factory will be greatly influenceed,
And cause stopping for its production line.
In conventional architectures, so that the above-mentioned missing of reinforcement, generally requiring significantly poppet intensity can keep away
Exempt from many doubts such as its failure, however, after being tested via actual operation, can still find, the action such as its reinforcement
Often take stopgap measures without effecting a permanent cure, it is impossible to be effectively prevented from the generation of above-mentioned condition.In addition, in above-mentioned framework,
Mould-forming chamber must offer two air pressure input ports and input valve port in above-mentioned two air pressure to be respectively communicated with
With two pressure sources, it will be apparent that, no matter it all more improve on setup cost or in manufacture difficulty.
Therefore, via above-mentioned explanation, those skilled in the art it is known that how to improve existing plastics
The technology of bottle manufacturing process, so that it is able to efficiently reduce the quantity that air pressure inputs valve port, and then is reduced defeated
Enter the Probability of valve port failure, be the primary emphasis of high pressure bottle blowing machine industry now；In view of this, this case
Inventor be strongly subject to study and composition, and finally research and develop complete the present invention high pressure switching valve, and by this
