The function of the valve is to intercept liquid or gas so that it cannot pass freely. Different types of valves have different purposes. Pneumatic ball valve is a valve widely used in aviation kerosene, natural gas, liquefied gas, gas transmission pipeline and other pipelines. Now we Shanghai valve manufacturers share and interpret the working principle and components of pneumatic ball valve!

氣動球閥的工作原理可以詳細分為以下幾個部分：

The working principle of pneumatic ball valve can be divided into the following parts in detail:

閥門關閉：

Valve closed:

當閥門關閉時，轉動手輪，使水龍頭和密封滑塊旋轉90度，然后向下移動水龍頭。隨著扳手的移動，密封閥芯被推入閥門內腔蓋，直到彈性密封圈均勻擰緊，使閥孔的上下端形成密封。

When the valve is closed, first turn the hand wheel to rotate the faucet and sealing slider 90 degrees, and then move the faucet downward. With the movement of the wrench, the sealing valve core is pushed into the inner cavity cover of the valve until the elastic sealing ring is tightened evenly, so that the upper and lower ends of the valve hole form a seal.

閥門開度：

Valve opening:

當閥門打開時，轉動手輪，抬起扳手并將密封滑塊從閥體兩側的密封面上拉回。當滑板完全縮回并離開閥體密封面時，繼續旋轉手輪，使水龍頭和密封滑板旋轉90，閥門處于開啟位置。

When the valve is opened, first turn the hand wheel, lift the wrench and pull the sealing slider back from the sealing surfaces on both sides of the valve body. When the sliding plate fully retracts and leaves the sealing surface of the valve body, continue to rotate the hand wheel to rotate the faucet and sealing sliding plate by 90, and the valve is in the open position.

關于密封：

About sealing:

彈性密封圈形成在滑板的凹槽中。隨著密封滑板進入閥門的入口和出口，密封圈逐漸壓入凹槽中。加工后的滑板表面與閥門內腔形成兩部分金金屬密封，防止彈性密封圈持續受壓，具有阻燃功能。

The elastic sealing ring is formed in the groove of the sliding plate. As the sealing sliding plate enters the inlet and outlet of the valve, the sealing ring is gradually pressed into the groove. The processed sliding plate surface forms two parts of gold metal seal with the inner cavity of the valve to prevent the continuous compression of the elastic seal ring, which has the function of flame retardant.

雙重通風：

Dual ventilation:

這是一種通過兩個截止閥和一個中間閥完全隔離兩端管道的方法。球閥關閉兩個主閥并打開閥，以提高系統性。如果閥門開始泄漏，過濾介質可能從打開的閥流出。

This is a method to completely isolate the pipes at both ends through two stop valves and an intermediate safety valve. The ball valve closes the two main valves and opens the safety valve to improve the safety of the system. If the valve begins to leak, the filter medium may flow out of the open safety valve.

雙重密封模式：

Double seal mode:

兩個獨立的密封滑塊牢固地壓入閥孔的上下端(雙重密封)。當閥門關閉時，溢流閥打開，以檢查密封效果(排放)。

Two independent sealing sliders are firmly pressed into the upper and lower ends of the valve hole (double sealing). When the valve is closed, the overflow valve opens to check the sealing effect (discharge).
