The problem of weak discontinuity in operation of vacuum
valve is considered from an experimental and theoretical point of view. A model
of gas flow as a function of two variable gas mass n and time t is created. The
model allows you to define a point on the time axis where the continuity of the
gas mass flow function breaks and define the discontinuity parameters. A model
of operation of the vacuum valve as a gas flow control device was built based
on the experimental data. It is shown that an inlet area inside the valve
through which gas flow passes has the property of a weak discontinuity,
provided that the area is considered as a time function. It is shown how this
property is transmitted to a gas discharge function. The described actions
result in the statement that the gas discharge function has the properties of
weak discontinuity over mass and time variables. The theoretical conclusions
were verified on a simple vacuum set with air overflow between two vessels,
provided that the gas flow is controlled by the valve. It found a single point
on the time axis where the gas discharge function has two weak discontinuities
over mass and time variables simultaneously. The phenomenon of weak
discontinuity in gas flow was recorded for the first time under such
experimental conditions.
