1. The quality pressed bend stored for a long time should be checked regularly. The exposed processing surface should be kept clean, the dirt should be removed, and it should be neatly stored in a ventilated and dry place indoors. It is strictly forbidden to store it in the open air. Always keep the quality pressed bend dry and ventilated, keep the holder clean and tidy, and store it according to the accurate storage method.
2. During installation, the quality pressed bend can be directly installed on the pipeline according to the connection method, and installed according to the position used. Under normal circumstances, it can be installed at any position of the pipeline, but it needs to be easily inspected for manipulation. Pay attention to the flow direction of the cut-off quality pressed bend medium should be upward from the bottom of the vertical valve disc, and the quality pressed bend can only be installed horizontally. When installing the quality pressed bend, pay attention to the tightness to prevent leakage and affect the normal operation of the pipeline.
3. When the quality pressed bend ball valve, globe valve and gate valve are used, they are only fully open or fully closed, and are not allowed to be used to adjust the flow, so as to avoid erosion of the sealing surface and accelerated wear. There are reverse sealing devices in the gate valve and the upper threaded globe valve. The handwheel is turned to the uppermost position and tightened to prevent the medium from leaking from the packing.
