APPARATUS FOR TESTING LEAK DETECTORS

摘要

Apparatus for testing a diaphragm or piston-type pressure-actuated detector of leaks in a hose, pipe, or other conduit. Fluid at a selected pressure is introduced into a manifold through the leak detector being tested, and the manifold is provided with a plurality of flow restrictors which allow flow at a selected rate at a selected pressure. In this manner, a leak detector which allows flow at a rate higher than a selected pressure can be rejected as not functioning properly. Further, the flow rate through that detector can also be tested at a given pressure. The apparatus is also capable of operating off of pressure developed by a submerged pump for testing the leak detector without removal of the leak detector from the submerged pump.
