Pressure test gauge.

摘要

A pressure test gauge is described, more particularly for testing the air pressure at the outlet of a spraygun. The pressure test gauge comprises a body (1) having an inlet (2) which may take the form of a replaceable screw in unit (3) sealed airtight with the body (1). The unit (3) encircles the inlet (2) and connects with passages (4, 5) passing through body (1). The passage (5) is a small bore tube which connects inlet (2) with a pressure gauge (6) which has a display (7). Intermediate the inlet unit (3) and gauge (6) is a valve (8) comprising a barrel (9) with an outer screw-thread (10) screwed into body (1); extending axially of valve (8) is a metering hole (11). The gauge body may have ribs (12) to facilitate gripping the body and a bracket (13) with screws (14) to secure it to a wall. <IMAGE>
