Piston type steam pressure pneumatic valve failure and eliminating methods

a, causes piston steam pressure pneumatic valve is not reducing or reducing failures and through several reasons:
and main pneumatic valve or pay a pneumatic valve sealing surface dirt, dirt can be removed.
and main pneumatic valve or pay a pneumatic valve sealing surface is damaged, will pay seal lapping repair or replacement.
, Lord, for pneumatic disc spring fatigue or broken, replace the new spring.
and feedback channel C holes blocked, clear away the dirt in the channel.
and diaphragm fatigue or damage, replace the diaphragm.
, piston cylinder wear or corrosion, processing and correction or replacement of the piston.
and piston ring groove and the ring sticking, remove the piston to clean.
, pneumatic valve body cavity filled with condensate, loosen the screw discharge condensate.
2,
solve impassability steam method, pneumatic valve cover is installed in the process of cleaning, remove the pneumatic valve cover location after installed.
and gasket on the displacement of plug in and out of the hole, make the gasket hole alignment in and out of the hole.
, access to pay for the pneumatic valve hole blockage, remove the dirt pneumatic valve cover to remove channels.
no, cause piston steam pressure pneumatic valve and reducing or reducing failure through several reasons:
and main pneumatic valve or pay a pneumatic valve sealing surface dirt, dirt can be removed.
and main pneumatic valve or pay a pneumatic valve sealing surface is damaged, will pay seal lapping repair or replacement.
, Lord, for pneumatic disc spring fatigue or broken, replace the new spring.
and feedback channel C holes blocked, clear away the dirt in the channel.
and diaphragm fatigue or damage, replace the diaphragm.
, piston cylinder wear or corrosion, processing and correction or replacement of the piston.
and piston ring groove and the ring sticking, remove the piston to clean.
, pneumatic valve body cavity filled with condensate, loosen the screw discharge condensate.

2, no steam, pneumatic valve cover is installed in the process of cleaning, remove the pneumatic valve cover location after installed.
and gasket on the displacement of plug in and out of the hole, make the gasket hole alignment in and out of the hole.
, access to pay for the pneumatic valve hole blockage, remove the dirt pneumatic valve cover to remove channels.
