氣動(dòng)球閥pneumatic ball valve

該閥門適用于水,溶劑,酸,蒸汽等一般工作介質(zhì),還適用于惡劣的介質(zhì)中,適用范圍廣。

The valves are suitable for water, solvents, acid, steam and the general working media, also applies to the bad medium, wide application scope.

特點(diǎn)(characteristic):

適用工作溫度為-29℃~150℃,其結(jié)構(gòu)緊湊,力矩小,密封可靠,維修方便,平等的閥體為介質(zhì)提供了阻力很小,而且易于操作。

Suitable temperature for - 29 ℃~ 150 ℃, its structure is compact, small torque, reliable sealing, convenient maintenance, full equality body provides the medium resistance is small, and easy to operate.

工作原理和結(jié)構(gòu)說明(the working principle and structure)

1.     本閥門主要由閥體,球心,密封件,閥桿等零件組成。

This valve is mainly composed of body, spherical centre, sealing ring ,valve stem and other parts.

2.     本閥門依靠氣動(dòng)執(zhí)行器,轉(zhuǎn)動(dòng)閥桿,使閥桿帶動(dòng)球心在介質(zhì)里作旋轉(zhuǎn)動(dòng)作,達(dá)到調(diào)節(jié)流速的目的。

This depend on the pneumatic valve actuator, turn the valve stem, the stem driving  the spherical centre spins in the medium for its rotary movement, its reach the purpose of regulating velocity.
