And are not intended to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation and, therefore, should not be taken to be limiting of the utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The tool for replacing the diaphragm of the pneumatic diaphragm regulating valve shown in fig. 1 or 2 comprises a circular upper clamp structure 100 made of steel and a circular lower clamp structure 200 arranged corresponding to the circular upper clamp structure 100 and shown in fig. 1.
With particular reference to fig. 1, a first annular cavity 110 is formed in the middle of the circular upper clamp structure 100. The two sides of the first annular cavity 110 are symmetrically provided with the mounting holes 120, the mounting holes 120 are symmetrically arranged along the axis of the first annular cavity 110, four mounting holes are arranged on each side, and the four mounting holes are arranged up and down in pairs.
