1, before installation, be sure to carefully check the various standards of stainless steel elbow, check whether the diameter meets the requirements of use, eliminate the defects caused by the transportation process, and remove the dirt of stainless steel elbow, and prepare for installation.
2, when installing, the stainless steel elbow can be directly installed on the pipe according to the connection method, and installed according to the position used. Under normal circumstances, it can be installed in any position of the pipeline, but it needs to be easy to operate maintenance, pay attention to the media flow of the stainless steel elbow should be upstream below the longitudinal valve disc, and the stainless steel elbow can only be installed horizontally. Stainless steel elbow should pay attention to sealing when installing to prevent leakage and affect the normal operation of the pipeline.
3, stainless steel elbow valve packing gland bolts should be evenly tightened, should not be pressed into a distorted state, so as not to hurt hinder the movement of the valve stem or cause leakage.
4, stainless steel elbow ball valve, globe valve, gate valve when used, only fully open or fully closed, not allowed to adjust the flow, so as to avoid the sealing surface erosion, accelerated wear. The gate valve and the upper thread stop valve have reverse sealing devices, and the hand wheel is turned to the upper position to tighten, which can prevent the medium from leaking from the packing place.
