Control Valve Pneumatic Diaphragm Customized Size Wear Resistance Tear Resistance
The installation steps of the pneumatic valve diaphragm are as follows:
1. Put the spring on the spring seat.
2. Install the diaphragm. When the diaphragm and the hard core are fixed, a loosening pad should be added to the screw cap to ensure that the diaphragm is flat and air-proof.
3. Therefore, grease should be applied to the fastening bolts before assembly, which is conducive to the next maintenance and lubrication.
4. Put on the upper membrane cover, fix it with a pair of eyebolts, and evenly and alternately tighten the eyebolts to complete the initial adjustment of the spring.
5. Tighten the fixed explosion nut on the membrane cover, and do not screw the eyebolt.
6. Install the connecting parts, and connect the supply line to the upper membrane cover.
7. After the above steps are completed, apply the following methods to verify.
Introduction:
Diaphragm is an important component of pneumatic diaphragm
actuator, when the air source is normal. If the actuator does not
move, you should think about whether the diaphragm is broken or not
installed properly. When there are defects such as sharp corners or
burrs on the surface of the metal contact surface, the diaphragm
will be punctured, and the diaphragm must not leak, the diaphragm
has been used for too long, and the material quality will also
affect the use. Before installation, check the parts for bumps,
damage, deformation, peeling paint or other abnormal phenomena, and
replace them if they are defective. Replaced parts must be
inspected and qualified before they can be used, and records should
be kept.
