Ексцентричен полусферичен кран

Ball valves are widely used in oil, gas, coal and ore mining, refining and processing and pipeline transportation systems; inchemical products, medicine and food production systems; inhydropower, thermal power and nuclear power power powerproduction systems; in urban and industrial enterprises watersupply and drainage, heating and gas supply systems; infarmland drainage and irrigation systems; in metallurgicalproduction systems An important mechanical product closelyrelated to production and constructionand people's life. Theball valve is sealed in allkinds of pipeline systems and is used to cut of or connect the medium fow, so that the medium can be transported to eachdesignated point according to the predetermined procedure.

Структурни характеристики

1. There is shear action between the cut ball core and the metal valve seat, which is especialy suitable for medium containing iber small solid particlesand slurry;

2. It has the ability of regulation and reliable positioning, the flow characteristic is approximate percentage, and the adjustable range is wide; 3. With the movable valve seat structure loaded by leaf spring, the valve seat and the ball core will not be jammed or separated. The sealing is relable andthe service life is long.
