Problems solved by technology

This method, while more cost-effective than trying to replace one or two valves individually, still creates considerable waste and consumes unnecessary maintenance cost resources
[0004] Most of these compressors have a substantial remaining useful life

Abstract

A first valve head is selected for removal from a piston cylinder. The first valve head has been configured to house at least a one way intake valve assembly in an intake chamber of the head and at least a one way exhaust valve assembly in an exhaust chamber of the head. The intake and exhaust chambers are sealed off from each other. The first valve head is removed from the piston cylinder. A second valve head is selected. A bottom of the second valve head is removably coupled to the piston cylinder. A concentric two way valve is seated within the second valve head. The concentric valve is secured within said second valve head with a valve clamp having a top cover. The top cover is removably coupled to the second valve head.

Description

Background technique [0001] Industrial compressors include three basic types: reciprocating, rotary screw, and rotary centrifugal. A reciprocating compressor is a positive displacement machine in which a piston moves within a cylinder, wherein the piston introduces compressible fluid into the cylinder on the downstroke and expels the compressible fluid by compressing the fluid on the upstroke. The expelled compressible fluid passes through a valve that prevents the expelled compressible fluid from returning to the cylinder. Thus, multiple reciprocations of the piston displace a large volume of compressible fluid into the fixed volume containment tank, thereby increasing the pressure within the containment tank with each reciprocation. The piston continues its reciprocating movement until the desired pressure is reached in the receiving tank. The piston reciprocates as necessary to maintain the desired operating pressure as the compressible fluid within the receiver is expell...
