Installation Steps And Knowledge Of Eccentric Reducer
When the ball valve, stop valve and gate valve of Oval eccentric reducer 600*350/219*3 are used, they can only be fully opened or fully closed. They are not allowed to be used to adjust the flow rate to avoid erosion of the sealing surface and accelerated wear. There are reverse sealing devices in the gate valve and the upper threaded stop valve. The handwheel is rotated to the upper position to welcome the user. The main difference between the elliptical eccentric reducer and the carbon steel elbow is the material difference. The chemical composition contained in it will maintain the important performance and operational value of the elbow in actual use. There are many things to pay attention to when using and maintaining the elliptical eccentric reducer. Users need to use it in a certain way and use and maintain it in an accurate and reasonable way.
When installing the elliptical eccentric reducer, the elliptical eccentric reducer can be directly installed on the pipeline according to the connection method and installed according to the position of use. Under normal circumstances, it can be installed at any position of the pipeline, but it needs to be easy to operate. Note that the flow direction of the medium of the cut-off elliptical eccentric reducer should be from the bottom of the longitudinal valve disc to the top. The elliptical eccentric reducer can only be installed horizontally. When installing the elliptical eccentric reducer, attention should be paid to the sealing to prevent leakage and affect the normal operation of the pipeline. The elliptical eccentric reducer plays an important role and value in installation and use, and produces good use operation in a certain environment and medium.
The precautions for the elliptical eccentric reducer are as follows: the elliptical eccentric reducer stored for a long time should be inspected regularly, and the exposed processing surface should be kept clean and cleaned. It should be neatly stored in a ventilated and dry place indoors. It is strictly forbidden to stack or store it in the open air. When the ball valve, stop valve, and gate valve of the elliptical eccentric reducer are used, they can only be fully opened or fully closed. It is not allowed to adjust the flow to avoid erosion of the sealing surface and accelerated wear. There is a reverse sealing device in the gate valve and the upper threaded stop valve. The surface of the head will not rust or corrode for a long time when the handwheel is rotated to the upper position. Always keep the elliptical eccentric reducer dry and ventilated, keep the device clean and tidy, and store it according to the correct storage method.
