ABSTRACT:
A tap to a process fluid line includes a pressure sensitive cap. The force necessary to remove the cap on the tap is directly proportional to the pressure buildup inside the cap so that an operator can take safety measures before removing the cap. The tap includes a base having a first set of reusable threads thereon and a cap having a second set of reusable threads therein which engage with the first set of threads on the base. A hollow fill tube communicates fluid from the process fluid line through a ball valve to a sample bottle when the cap is removed. The resistance provided by the reusable threads is linear and consistent throughout the entire threading and unthreading procedure. In this manner the force necessary to remove the cap is proportional to the pressure buildup inside of the cap. A helical spring is attachable by an anchor to the fill tube and can be employed to steady the mouth of the sample bottle as it is filled by the fill tube. The invention helps to prevent industrial accidents by minimizing the hazard of sample fluid spills and by warning the operator of the buildup of dangerous pressure inside the cap prior to its removal.
