Electric ball valve installation test
Get an electric ball valve in the hand, what is difficult to install, a small thing. When is this true? In fact, the ball valve installation is not in place, it is easy to affect the good use later, maybe it will affect the entire operating system. Especially for beginners, installing ball valves is also a big test!
In order to avoid unnecessary follow-up troubles, you must strictly follow the three phases before installation, during installation, and after installation.
Before installation: Remove the protective parts on both ends of the ball valve, that is, on the connecting flange; prepare the pipelines before and after the electric ball valve to ensure that the front and rear pipes are parallel to the sealing surface of the flange; if the ball valve is not installed on the ground, it must be done. Good and proper support to ensure that it can withstand the weight of the ball valve; check all signs on the ball valve to ensure correctness; keep the pipeline clean, Bunn that has oil, welding slag and other impurities into the pipeline; clean the valve hole, because There will be small particles that damage the sealing surface.
installing:
Although for the veteran, the electric ball valve installation process is very skilled, but Xiaobian still need to repeat with you once, first need to install the pipeline on the valve, followed by symmetrical, uniform, one by one tighten the bolts on the flange, then Need to connect the electric pipeline, if you think there is an error in position, you can use the handle to drive the valve, can be installed anywhere in the pipeline. If it is an electric ball valve with gear box, it should be installed in an upright manner. In simple terms, it is horizontally installed on the pipeline.
Post-installation inspection work:
It is not the end of the above work, there are some valve inspections after installation can not be ignored, such as checking the number of times the driver opens and closes the valve, whether there is inflexible operating conditions; for example, according to the pipeline design requirements need to the pipeline Check the sealing with the flange joint between the valve.
