With the development in recent years, the application of pipeline electric ball valve has become more and more extensive. It has become a new product for the connection of pumps, valves, pipelines and other equipment with pipelines. They are connected by bolts to make them become a whole with a certain displacement, so that they can be adjusted according to the on-site installation size during installation and maintenance, The axial thrust can be transmitted to the whole pipeline system. This not only improves the working efficiency, but also plays a certain role in protecting pipeline equipment such as pumps and valves. Due to the rapid expansion of the market, small electric ball valve manufacturers have developed rapidly. However, small manufacturers have a low starting point, very weak technical force, and simple equipment. Most of their products are imitation production, with uneven quality. The electric ball valves produced by them generally have the shortcomings of external leakage, internal leakage, low appearance quality, short life, inflexible operation, and unreliable materials. Therefore, when purchasing electric ball valves, we should choose reliable and powerful manufacturers to buy high-quality products. In normal applications, the electric ball valve may also be damaged due to improper use or failure to fully consider the use environment when using it. What are the reasons for the failure of the electric ball valve?
Firstly, the applicable temperature of the transmission medium must be considered when using the electric ball valve. Generally, the temperature of the medium cannot be higher than 300 degrees. If the medium is acidic or alkaline, it is necessary to communicate clearly with the manufacturer, and adjust the manufacturing process of the electric ball valve according to the medium use requirements to meet the requirements, otherwise the electric ball valve may be damaged. In addition, the expansion length of the electric ball valve position is not enough in use. Forcibly exceeding the expansion length and randomly expanding the contraction range may also cause damage to the electric ball valve. In addition, the strength of the electric ball valve interface is not high enough. If the installation method is not accurate, the strength of the connector will become low, which may lead to damage of the electric ball valve.
The installation of electric ball valve is to adjust the length of both ends of the product to adapt to the distance between the two ends, then tighten the gland bolts with the diagonal method, adjust the limit bolts, and fix the maximum limit range, so that the pipeline can stretch freely within the expansion range, and will be limited when reaching the maximum displacement distance. This can effectively prevent the electric ball valve from being damaged and leaking due to excessive pipe displacement for other reasons. When the electric ball valve is installed in the open air, the sun exposure and contact with acidic and alkaline materials shall be avoided as far as possible, otherwise the electric ball valve will be corroded and damaged after a long time. It is also important to note that after the installation of the electric ball valve, if the pipeline is severely deformed and the extension of the electric ball valve in other places exceeds its expansion range, the electric ball valve will also be damaged.
