Bourdon tube pressure gauge fixing appts.

摘要

The appts. includes a connection pipe (18), a sealing ring, and a fixing screw (36). Deformation of the bourdon tube is converted to movement of a pointer (19) on a dial (20) and the pressure gauge is fixed at a fluid pressure mounting which has connection for pressure measurement. The connecting tube is fixed at the pressure gauge so that one of its ends is connected with the bourdon tube (17). The pies other end protrudes from the rear surface of the pressure gauge (1). The sealing ring is in the fluid pressure mounting for the pressure measurement. The sealing ring has an inner dia. which is smaller than the dia. of the connecting tube. If the connecting tube is pressed in a gap between the outer circumferential surface of the connecting tube and an inner periphery wall of the connection, the sealing ring seals the connection. The fixing screw is fixes the pressure gauge at the fluid pressure mounting, if the connecting tube is in the sealing ring.
