Ventilation tube and accompanying system

Abstract

The ventilation tube and system of the present invention comprises a ventilation pipe designed to properly aerate drainage systems and prevents overflow of system fluids into the atmosphere or onto the ground.

1 . a ventilation tube comprising: 
 a cylindrical member;    a spherical member, designed to fit within said cylindrical member;    means for attachment to a fluid piping system including a pumping mechanism;    wherein said spherical member prevents fluid from leaving said cylindrical member and    creates a backflow which deactivates said pumping mechanism.    
   
   
       2 . The ventilation tube of  claim 1  further comprising a switch which when depresses by said spherical member deactivates said pumping mechanism.  
   
   
       3 . The ventilation tube of  claim 1  further comprising a system of graduated markings positioned along said outer surface of said cylinder.  
   
   
       4 . The ventilation tube of  claim 1  further comprising an annular end cap located at said distal end.  
   
   
       5 . The ventilation tube of  claim 1  wherein said annular end cap includes a series of cavities.  
   
   
       6 . The ventilation tube of  claim 1  wherein said spherical member is a ball.  
   
   
       7 . The ventilation tube of  claim 6  wherein said ball is of a hollow stainless steel construction.  
   
   
       8 . The ventilation tube of  claim 6  wherein said ball is of a PVC construction.  
   
   
       9 . The ventilation tube of  claim 6  wherein said ball is of a plastic construction.  
   
   
       10 . The ventilation tube of  claim 1  wherein said spherical member is a disc.  
   
   
       11 . The ventilation tube of  claim 1  wherein said ventilator tube is an indicator vent.  
   
   
       12 . The ventilation tube of  claim 1  wherein said ventilator tube is a forced main vent.  
   
   
       13 . The ventilation tube of  claim 1  wherein said ventilator tube is composed of PVC pipe.  
   
   
       14 . The ventilation tube of  claim 1  wherein said ventilator tube is composed of schedule  40  PVC pipe.  
   
   
       15 . The ventilation tube of  claim 1  wherein said graduated markings extend 24 inches.  
   
   
       16 . The ventilation tube of  claim 1  wherein said graduated markings extend 39 inches.  
   
   
       17 . The ventilation tube of  claim 1  wherein said tube is 2 inches in diameter.  
   
   
       18 . The ventilation tube of  claim 1  wherein said tube is 4 inches in diameter.  
   
   
       19 . The ventilation tube of  claim 1  wherein said tube is at least 6 inches in diameter.  
   
   
       20 . A ventilation apparatus comprising: 
 a hollow shaft comprising of a top end, a bottom end, and an outside perimeter wherein said outside perimeter is marked with graduations;    a top seal attached to said top end;    a bottom seal attached to said bottom end; and    a sphere within said hollow shaft which is allowed to traverse from said bottom end to said top end.
