Precautions for installation function of double flange limit electric ball valve: double flange limit double flange limit electric ball valve is applicable to the connection between both sides and flanges. During installation, adjust the connection length between both ends of the product and flanges, tighten the gland bolts diagonally and evenly, and then adjust the limit nuts, so that the pipeline can expand and contract freely within the scope of expansion and contraction, and lock the expansion and contraction amount, Ensure the safe operation of the pipeline. When it is convenient for installation and maintenance, it shall be adjusted according to the site size. The double flange limit electric ball valve can reduce the pressure thrust (blind plate force) of the connected parts and compensate the installation error of the pipeline. The double flange limit electric ball valve is mainly used for the connection of pumps, valves and other accessories. Material: mainly Q235 carbon steel, stainless steel, cast steel, ductile iron, etc.
Different materials and models are used for different purposes. The double flange limit electric ball valve is applicable to the steam and hot water pipelines where the delivery temperature is not higher than 450 degrees.
2、 Function introduction of electric ball valve: CS type electric ball valve for thermal pipeline is composed of telescopic sleeve, pressure plate and telescopic body. The double flange limit electric ball valve is mainly used in the steam pipe sector to compensate the displacement of the steam pipe due to thermal expansion and cold contraction. Advantages of electric ball valve: large expansion, easy installation and maintenance. Electric ball valve features: high pressure and high temperature resistance. 3、 Precautions for installation of electric ball valve 1. Before installation, loosen the pressure plate bolt, lengthen the electric ball valve to the installation length, and then tighten the bolt diagonally to avoid bias.
2. The electric ball valve shall be installed between two fixed supports on the straight section of the pipeline. In order to ensure the normal expansion of the electric ball valve and prevent it from pulling off, the double flange limit electric ball valve shall be equipped with a guide support and a gear.
