A kind of application method of flange clamp device of the utility model:
The fastening of flange is generally divided into installation fastening, online fastening and three kinds of modes of protective demolition.The utility model
In flange clamp device be suitable for above-mentioned several applying working conditions simultaneously.
When normal flange installation fastening, all bolt and gasket are installed with the help of external force first in place,
It not fastened, be in all nut 2 and gasket in the state of the non-stress of nature installation, then fastening kit 1 is installed
With swivel nut locator 7, connection hydraulic tube 43, then setting pressure setting regulating valve 5 numerical value, finally starting hydraulic pump 412 into
The interim pressurization of row, every pressurization is primary, and external force is needed to fasten a swivel nut locator 7, concurrently sets a pressure setting and adjusts
The setting value of valve 5, progress and so on just can guarantee that the stress of each valve is consistent, until hydraulic coupling reaches corresponding torsion
Fastening is completed when square power.When dismounting, needs to set the progress pressure release of regulating valve 5 by pressure first, set and adjust in pressure
After valve 5 is fully open, stops the operation of hydraulic pump 412, hydraulic tube 43 is removed after one minute, and removes swivel nut positioning one by one
Device 7 and fastening kit 1.
It is similar with operating procedure above when online clamp flange, uniquely it should be noted that every once fastened
The detection for needing to carry out leak case, the amplitude for concurrently setting pressure need additionally slow, prevent so that metal gasket moment
Deformation causes more serious leakage.
The purpose of protective demolition is in order to prevent when removing flange because torsional forces unevenly causes flange
Deformation or the deformation of gasket and the operation that carries out, basic operational steps and like above, uniquely it should be noted that hydraulic stem
12 installation direction is that opposite direction is installed or the installation direction of swivel nut 11 is opposite direction installation at this time, so installing each
The direction that additional attention rotation is needed when swivel nut 11, prevents the installation situation of mistake.
