Imported pneumatic Angle seat valve installation, pay attention to, and maintenance methods

a installation instructions
. Check pneumatic pneumatic valve model, parameter meets the installation requirements and technical requirements.
。 Check pneumatic pneumatic cylinder valve, position indicator, to ensure that no damage.
。 Must blow the pneumatic pneumatic valve pipe cleaning, sweep clean; Contains impurities such as medium, in front of the pneumatic valve filter should be equipped with pneumatic valve in the pipeline.
。 According to the pneumatic pneumatic valve pneumatic the direction of the arrow on the valve installation ( Downstream installation) The pneumatic interface of pneumatic valve and pipeline connection, and ensure good seal joint.
。 Such as adding electromagnetic pneumatic valve, pay attention to the joint to ensure good seal.
。 Need welding connection, avoid high temperature reached the place such as pneumatic pneumatic valve packing.
2 pneumatic pneumatic valve installation and equipped with solenoid pneumatic valve note
. Must ensure that the fluid flow, the air is clean, in case of jam solenoid pneumatic valve piston and cylinder.
。 The electromagnetic coil of pneumatic valve charged high fever during the normal work, please do not touch.
。 Electromagnetic solenoid coil charged, banned removed, in order to prevent electric shock.
。 Electromagnetic coil of pneumatic valve and outlet, electromagnetic pipe and connection parts, it is strictly prohibited to hit the collision, so as to avoid damage.
。 Electromagnetic solenoid coil charged, it is forbidden to cover, burned to prevent overheating.
。 Actual power supply voltage of pneumatic valve can not beyond the tolerance range.
。 Medium pressure, working temperature, viscosity, shall not exceed the scope of regulation.

3 maintenance method. Prior to the demolition pneumatic pneumatic valve must be emptying fluid in the cylinder, drainage to pneumatic valve within the medium pressure; If the medium is high temperature and high pressure inflammable, explosive, toxic and corrosive, must be thoroughly cleared, in case of personal and equipment damage.
。 Pneumatic pneumatic valve disassembly steps:
A split cylinder: remove the locking ring, lift and remove the cylinder, piston, spring can be seen, position indicator, pneumatic valve rod and other components.
B split pneumatic valve body: use a wrench in pneumatic valve cover rotate the root, can remove the pneumatic valve body, see the pneumatic valve body parts.
C split seals: after open the pneumatic valve body, can see at the end of the pneumatic valve stem seal, under the fixed seal screw, can remove the seal.
。 According to the fault analysis, to open the pneumatic valve and the corresponding processing.
。 Processed, refer to remove the step installation at a time.
。 Seal, locking ring, sealing ring and spring components must be installed, tighten the fittings, the strength should be uniform. Disassembly and installation process should pay attention to don't touch hurt diaphragm and pneumatic seat.
。 Pneumatic valve repair good, must do pressure test and leakage test, no abnormal to install and use again.
