Pneumatic cryogenic regulator installation and use precautions

Pneumatic cryogenic regulator installation and use precautions

1. It should be installed vertically on the horizontal pipe. When it is necessary to install it horizontally or obliquely under special circumstances, it should generally be supported. The panel mounted on the wall of the incubator should be parallel to the wall of the incubator.
2, should be installed close to the ground or floor, in order to maintain and repair, for those with a valve positioner or handwheel mechanism, should also ensure observation, adjustment and operation and convenience.
3. The bypass line is generally set to switch to manual operation when the automatic control system fails or the maintenance valve is repaired, so that production is not stopped.
4. When the handwheel mechanism is installed, the manual operation can also be omitted when the bypass pipe is omitted, and it can also be used to limit the opening degree of the valve. When the use is stopped, the handwheel mechanism must be restored to the original neutral position to facilitate the normal operation of the automatic control system.
5. When installing the ZMAP pneumatic low temperature control valve, the flow direction of the medium should be consistent with the direction indicated by the valve body.
6. The regulating valve should clean the pipeline and clean the welding slag before installation. After installation, make the regulating valve fully open, clean the pipeline, valve, etc. and test the tightness of each joint.
