Ball valves, globe valves, and gate valves with quality pressed bend are only fully open or fully closed, and are not allowed to be used for flow adjustment, so as to avoid erosion of the sealing surface and accelerated wear.
Ball valves, globe valves, and gate valves with quality pressed bend are only fully open or fully closed, and are not allowed to be used for flow adjustment, so as to avoid erosion of the sealing surface and accelerated wear. There are inverted sealing devices in the gate valve and the upper threaded globe valve, and the handwheel is rotated to the upper position to welcome users. The main difference between quality pressed bend and carbon steel elbow is the difference in material, and the chemical composition contained in it will keep the elbow in actual use and produce important performance and operational value. There are many things that need to be paid attention to when using and maintaining the elbow. Users need to use it in a certain way, and use and maintain it in an accurate and reasonable way.
When the quality pressed bend is installed, 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 cut-off quality pressed bend. The flow direction of the medium should be upward from the bottom of the vertical valve flap, and the elbow 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. The quality pressed bend has an important role and value in installation and use, and produces a good use operation in a certain environment and medium.
The precautions for quality pressed bend are as follows: The quality pressed bend stored for a long time should be checked regularly, and the exposed processing surface should be kept clean and dirty, and stored neatly in a ventilated and dry place indoors. It is strictly forbidden to store it in the open air. Elbow ball valves, globe valves and gate valves are only fully open or fully closed, and are not allowed to be used for flow regulation, so as to avoid erosion of the sealing surface and accelerated wear. There are inverted sealing devices in the gate valve and the upper threaded globe valve, and the surface of the handwheel will not rust or be corroded for a long time when the handwheel is rotated to the upper position. Always keep the quality pressed bend dry and ventilated, keep the holder clean and tidy, and store it according to the accurate storage method.
