Pneumatic pressure adjustment valve product safety attention

security pressure pneumatic valve adjustment including the discharge pressure and back pressure. In the adjustment, the height of the pneumatic valves must be open to all and for action. So before adjusting safety pneumatic valve, want to do a good job of protection device.
before the fluctuation adjustment ring, pneumatic valve inlet pressure should be adjusted appropriately makes the pressure to reduce, prevent in regulating pneumatic valve when suddenly open, cause an accident. In regulating coil change of back pressure at the same time, should also pay attention to safety of pneumatic valve discharge pressure, higher raised ring makes the discharge pressure increased, reduce the adjusting ring makes the discharge pressure is reduced, but when the adjusting amplitude should not be too big, fine-tuning will solve the problem.
some security pneumatic valve products with recoil and pneumatic seat adjust the structure of circle, this kind of security when making adjustment in the pneumatic valve products, must be unscrewed the adjusting ring fixed screw, use thin stick a tool a dial to adjust the ring gear, which makes adjust rotate around the circle. Higher counterclockwise, its location, pneumatic valve discharge pressure and back pressure are lower; Value the clockwise rotation of the position is reduced, the discharge pressure and back pressure pneumatic valve were elevated. It is worth noting that the adjustment, the ring spinning amplitude shoulds not be too large, generally only need to turn a number of tooth. After adjust should be fixed on the screw, make its ministry within the groove between the adjusting ring, this will convenient adjustment ring rotation, and make the adjustment ring radial pressure.
