中文简体The laying of various pipelines in life requires the use of copper valves, and in order to ensure its use effect when we use it, we should also pay attention to the methods and matters during installation, so what is the correct installation method?
Before operation, the front and rear pipelines of the valve should be purged to remove oil, welding slag and all other impurities in the pipeline. Check the valve hole to remove possible dirt, then clean the valve hole. Even small particles of foreign matter may damage the sealing surface of the valve seat, so it must be cleaned carefully.
Install the valve into the pipeline, either end can be installed upstream, but valves with gearboxes or pneumatic actuators should be installed upright. Install the gasket between the valve flange and the pipeline flange according to the pipeline design requirements, and the bolts need to be tightened symmetrically, one by one, and evenly, and then the pneumatic pipeline is connected.
Of course, in order to ensure its use effect, it should be checked after the end. It should be flexible and free of stagnation, and it can work normally. It is safe to use.
