Abstract

A flow sampler device which can be employed in a catalytic reactor system comprises a sample receiver, and an inlet and outlet valve which are each in fluid communication with the receiver. Each of the valves includes a valve stem which is rotatable about a longitudinal axis thereof so as to actuate the respective valve and has a collar element secured thereto. This collar element has a first end and a second end and comprises a wall means which defines a longitudinal passageway therethrough. The collar element also includes a locking slot which is defined therein and which includes a first portion extending from the first end of the element and a second portion which is substantially perpendicular to the first portion. In a preferred embodiment, the collar element is cylindrical and the locking slot is substantially L-shaped. The collar element effectively prevents a wrench which operates the valve from being removed from the valve stem when the valve is in a open position.
Thus, because only one valve is open at any one time, the reactor is not allowed to vent through the sampling device.
