    詳情介紹:

    一、概述Outline

    QJ(D/S)DX型精小型氣動橡膠蝶閥是由氣動活塞式執行機構和襯里蝶閥組成,屬旋轉類控制閥。
    該產品以壓縮空氣為動力源,接受控制儀表的4-20mA信號(或開關信號),通過電-氣閥門定位器(或電磁閥)實現對閥門的連續調節(或位式控制)。
    橡膠襯里蝶閥是一種閥體內腔襯有橡膠的防腐蝕蝶閥??刂聘g性流體不與閥體接觸,閥體可用普通鑄鐵或碳鋼,由此降低蝶閥的成本。襯里材料有各種橡膠可供選擇,還可更換。
    該產品結構簡單,輸出力矩大,性能優越。蝶閥通常適用于控制密封要求比較高的腐蝕性流體。

    QJ (D / S) DX-type fine small pneumatic rubber valve is pneumatic piston actuator and lining butterfly valve, is a rotary type control valve.
    The product is compressed air as power source, to accept 4-20mA control signal meter (or switch signals), through the electric - gas valve locator (or solenoid valve) to achieve the continuous adjustment of the valve (or bit control).
    Rubber lined butterfly valve is a body cavity lined with rubber anti-corrosion butterfly. Corrosion control and body fluid does not contact the valve body can be an ordinary cast iron or steel, thus reducing the cost of butterfly. There are a variety of rubber lining materials available, can be replaced.
    The product is simple, the output torque, and superior performance. Control valve normally sealing requirements for high corrosive fluids.
