粉塵蝶閥dust butterfly valve

該閥門適用于化工，石油，機(jī)械等行業(yè)。

The valve is suitable for chemical, petroleum, machinery and other industries.

特點（characteristic）：

結(jié)構(gòu)簡單，維修方便，阻力小，操作簡單，耐磨損，耐腐蝕，耐高溫，使用壽命長，易安裝，適用的介質(zhì)有液體，粉體。

Simple structure, convenient maintenance, small resistance, simple operation, wear resistance, corrosion resistance, high temperature resistant, long service life, easy installation, applicable medium is liquid, powder.

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，閥板，支架，閥桿等零件組成。

This valve is mainly composed of body, Valve plate, stent, Valve stem and other parts.

2.     本閥門依靠氣動執(zhí)行器，轉(zhuǎn)動閥桿，使閥桿帶動閥板在介質(zhì)里作旋轉(zhuǎn)動作，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 Valve plate spins in the medium for its rotary movement, its reach the purpose of regulating velocity.
