  1. 2018年6月8日 · 球閥(Ball valve) 又稱 球塞閥 ,為一種常見的主要閥類,是由塞閥改良而來,以球體取代柱塞。 球體設有一貫穿孔,旋轉球體可控制貫穿孔與流道的配合以調整閥門啟閉。 閥座可依工作條件選用適合的材質, 因密封性佳且構造簡單易於操作及維修而廣泛運用 。 球型閥(Globe valve) 因外形似球而稱之,以閥板與閥座之配合開啟或關閉流道,常用於截斷及節流。 閥體內流道呈S型,流體經過時將改變流向,使阻力增加故流體壓力下降 。 閘閥(Gate valve) 利用閥桿帶動閘板做直線運動,以閘板升降開啟或關閉流道。 閘板半開使用時,流體衝擊閘板易造成閥座震動而損傷,故 不適合節流使用,僅適用全開或全關場合 。 止回閥(Check valve)

  2. 球閥 ( Ball valve )是一種 流體流量控制裝置 ,使用中空、多孔且可擺動的球來控制流經它的流體。 當球中央的孔與流入口對齊時,它處於打開狀態,當它被閥手柄擺動90度時,封閉孔,使流體停止流動 [1] 。 在打開時,手柄與流動方向保持平齊,而在關閉時,手柄垂直於流動方向,便於視覺上確認閥的狀態 [2] 。 關閉位置的1/4旋轉可以是 順時針 或逆時針方向。 球閥耐用,經過多次循環後性能良好,可靠,即使長時間不使用後仍能安全封閉。 這些特點使其成為切斷和控制應用的優秀選擇,通常優於 閘閥 和截止閥,但在節流應用中它們缺乏細微的控制。

    A ball valve is a flow control device which uses a hollow, perforated, and pivoting ball to control fluid flowing through it. It is open when the hole through the middle of the ball is in line with the flow inlet, and closed when it is pivoted 90 degrees by the valve handle, blocking the flow. [1] .

  4. 2016年10月1日 · A ball valve is a type of quarter-turn valve that uses a hollow, perforated, and pivoting ball to control flow through it. Learn more about the working principle of a ball valve and the most common types.

  5. 2024年1月28日 · A ball valve is a type of valve that uses a spherical perforated obstruction (a rotary ball) to stop and start the hydraulic flow. A ball valve is usually rotated 90 (quarter-turn valve) around its axis to open and close. It is one of the most widely used valve types.

  6. 2024年2月26日 · 球阀 ( Ball valve )是一种 流体流量控制装置 ,使用中空、多孔且可摆动的球来控制流经它的流体。 当球中央的孔与流入口对齐时,它处于打开状态,当它被阀手柄摆动90度时,封闭孔,使流体停止流动 [1] 。 在打开时,手柄与流动方向保持平齐,而在关闭时,手柄垂直于流动方向,便于视觉上确认阀的状态 [2] 。 关闭位置的1/4旋转可以是 顺时针 或逆时针方向。 球阀耐用,经过多次循环后性能良好,可靠,即使长时间不使用后仍能安全封闭。 这些特点使其成为切断和控制应用的优秀选择,通常优于 闸阀 和截止阀,但在节流应用中它们缺乏细微的控制。

  7. Ball valves are quarter-turn on/off devices. A pivoting ball in the center of the valve controls the flow of liquid or gas media. The pivoting ball is known as a rotary ball, and it is designed with a hole (a bore) in the center. A stem on the top of the ball rotates the ball to open or close the valve.

  8. 2023年11月17日 · A ball valve is a type of shut-off valve used to regulate the flow of liquids, vapors, and gases within a piping system. It operates by rotating a spherical ball situated within the valve body.

    Ball valves can be used in transmission and storage, gas processing, industrial applications, and many more. They provide reliable leak protection, which is especially beneficial in gas applications. Ball valves have low pressure drop and can open and close

  10. 2020年8月20日 · Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that rotates to open and close the valve. Ball valves are used in situations where tight shut-off is required.
