止回閥

型號:

發布日期:05-28

產品詳情

    止回閥是指啟閉件為圓形閥瓣并靠自身重量及介質壓力產生動作來阻斷介質倒流的一種閥門。屬自動閥類,又稱逆止閥、單向閥、回流閥或隔離閥。閥瓣運動方式分為升降式和旋啟式。

    止回閥可用于給其中的壓力可能升至超過系統壓的輔助系統提供補給的管路上。止回閥主要可分為旋啟式止回閥(依重心旋轉)與升降式止回閥(沿軸線移動)。

    止回閥這種類型的閥門的作用是只允許介質向一個方向流動,而且阻止反方向流動。通常這種閥門是自動工作的,在一個方向流動的流體壓力作用下,閥瓣打開;流體反方向流動時,由流體壓力和閥瓣的自重合閥瓣作用于閥座,從而切斷流動。


Product Details

     Check valve is a valve in which the opening and closing member is a circular flap and acts on its own weight and medium pressure to block the flow of the medium. It is an automatic valve, also known as a check valve, check valve, return valve or isolation valve. The flap motion mode is divided into lift type and swing type.

     The check valve can be used to supply a line in which the pressure may rise to an auxiliary system that exceeds the system pressure. The check valve can be mainly divided into a swing type check valve (rotation according to the center of gravity) and a lift check valve (moving along the axis).

     Check valves the role of this type of valve is to allow only the medium to flow in one direction and to prevent flow in the opposite direction. Usually, the valve is automatically operated, and the valve flap is opened by the fluid pressure flowing in one direction; when the fluid flows in the opposite direction, the fluid pressure and the self-reclosing valve flap of the valve disc act on the valve seat, thereby cutting off the flow.
