Structure features:
A extension tube is added to ball launching barrel to balance initial
pressures before and after the pipe cleaner. When initiating the ball,
owing to the pressure applied upon the cleaner which, in turn, is moving
towards the check valve (or globe valve) core, the opening at this moment
will certainly damage the valve core to cause valve breaking and inability
to seal. The balance extension tube functions to retain balanced pressure
in front and at the back of the cleaner prior to the opening of the valve to
prevent it from impacting the valve core.
