Multi-Part Valve Assembly

Abstract

The present invention discloses a multi-component valve system for use in pumps such as fracking pumps for use in subterranean resource production. The assembly includes a retaining pin, a guide on the retaining pin, a valve on the retaining pin, an insert on the retaining pin, a retainer above the insert on the retaining pin, and a retainer cap inertia welded to the end of the retaining pin. In a particular embodiment, the guide component is stamped and folded to create the desired shape.

1 . A valve assembly, comprising:
 a retaining pin;   a guide located on the retaining pin;   the guide having a central portion;   a valve located on the retaining pin on top of the guide;   an insert located on the valve;   an insert retainer located on the retaining pin above the insert;   a retainer cap located above the insert retainer and affixed to the retaining pin;   a plurality of legs extending downward from the central portion;   a footer extending outward from each leg; and,   a stabilizer extending downward from the top portion between each of a pair of the legs.   
     
     
         2 . The valve assembly of  claim 1 , the guide further comprising:
 a recess formed on a bottom side of the valve; and,   the central portion of the guide located inside the recess to position the guide concentrically with the valve.   
     
     
         3 . The valve assembly of  claim 1 , further comprising:
 a recess formed on a bottom side of the valve;   the central portion of the guide having externally extending tabs; and,   the tabs located inside the internal circumference of the valve recess.   
     
     
         4 . The valve assembly of  claim 1 , further comprising:
 the retainer cap having a nonagon configuration.   
     
     
         5 . The valve assembly of  claim 1 , further comprising:
 the retaining pin having a generally triangular head.   
     
     
         6 . The valve assembly of  claim 1 , further comprising:
 the legs bent-formed from the central portion;   the footers bent-formed from the guide legs; and,   the stabilizers bent-formed from the central portion.   
     
     
         7 . The valve assembly of  claim 1 , further comprising:
 the guide stabilizers and the guide legs forming a substantially continuous structure.   
     
     
         8 . The valve assembly of  claim 1 , further comprising:
 the retaining pin engaging at least two stabilizers of the guide.
