Precautions in the use of pneumatic ball valves What are the precautions in the use of pneumatic ball valves? Pneumatic ball valves are equipment devices used for the safe operation of pumps, valves and other equipment and pipeline systems. Pneumatic ball valves have the advantages of long compensation interval and small pressure loss during construction and use. Generally, A set of bellows pneumatic ball valves can be designed according to 1-15mm, and can be installed at any position on the straight line between two fixed points of the pipeline, so as to facilitate the use of bellows pneumatic ball valves.
In use, the number of pneumatic ball valves is relatively small, while the corrugated pneumatic ball valves of pressure vessels themselves do not produce pressure drop, and the pressure drop of steam transmission is relatively small. Compared with the axial bellows, the pressure drop of the compensation method is 0.02~0.03MPa/km smaller, which is very important in realizing long-distance heat supply. The double flange loose sleeve pneumatic ball valve is made by adding flange stub pipe and valve screw on the basis of the flange loose sleeve compensation joint. The difference between the secondary type of compensation joint and loose sleeve compensation joint and loose sleeve limit compensation joint is that its compensation amount refers to the adjustment amount during installation and disassembly. Once all nuts are tightened, it is rigidly connected and can transmit axial force, So as to protect valves, pumps and other equipment. CC2F double flange loose sleeve valve scope of application CC2F double flange loose sleeve pneumatic ball valve is suitable for conveying sea water, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and granular powder with temperature not higher than 250 degrees.
Brief Description of Installation The double flange loose sleeve pneumatic ball valve is applicable to the pipeline connected with flanges on both sides. During installation, adjust the installation length of both ends of the product and flanges, and tighten the gland bolts diagonally and evenly to make them a whole, with a certain displacement, so that they can be adjusted according to the site size during installation and maintenance. During operation, the axial thrust can be transmitted to positive pipes. Materials of double flange loose sleeve pneumatic ball valve: mainly Q235 carbon steel, stainless steel, cast steel, ductile iron, etc. Different materials and models are used for different purposes.
