Introduction of whole machine test before safety of welding ball valve

After connecting the welded ball valve with the pipeline, the bolts of the flange connection must be cross-locked with the prescribed torque; before connecting the welded ball valve with the pipeline, the residual impurities in the pipeline must be removed; during installation, the actuator part of the welded ball valve can not be used as the lifting point to avoid damaging the actuator and attachment. Pieces.
Welded ball valves should be installed in the horizontal or vertical direction of the pipeline; the pipeline near the installation point of welded ball valves should not be drooping or bearing external forces, and pipeline support or support can be used to eliminate deviation of the pipeline; before installation of welded ball valves, the whole machine should be tested according to the specified signal, and only after passing can they be installed. Wire installation; flush the welded ball valve completely open.

Welded ball valves should be installed in strict accordance with the requirements of the product specifications. If the installation of welding ball valves is wrong, it will cause great impact in the later operation.
