Differential pressure (差壓 式) valve

摘要

This differential pressure-type valve is designed to open and shut a valve at high speed using the pressure of the fluid which flows through the interior of the valve. The valve apparatus is mainly composed of a circular barrel pipe(4), an upper and lower operating bar(6), a main valve(12), a supporting valve(8) and a small valve(11) . This invention is characterized by the regulation using low power of the upper and lower operating bar(6) regardless of the size of the valve.
