進口法蘭球閥工作原理：

進口法蘭球閥開啟過程：

1在關閉位置，球體受閥桿的機械施壓作用，緊壓在閥座上。

2當逆時針轉動手輪時，閥桿則反向運動，其底部角形平面使球體脫開閥座。

3閥桿繼續提升，并與閥桿螺旋槽內的導銷相互作用，使球體開始無摩擦地旋轉。

4直至到全開位置，閥桿提升到極限位置，球體旋轉到全開位置。

進口法蘭球閥關閉過程：

1關閉時，順時針旋轉手輪，閥桿開始下降并使球體離開閥座開始旋轉。

2繼續旋轉手輪，閥桿受到嵌于其上螺旋槽內的導銷的作用，使閥桿和球體同時旋轉90°。

3 快要關閉時，球體已在與閥座無接觸的情況下旋轉了90°。

4手輪轉動的zui后幾圈，閥桿底部的角形平面機械地楔向壓迫球體，使其緊密地壓在閥座上，達到*密封。

Inlet flange ball valve working principle:

Inlet flange ball valve opening process:

1 in the closed position, the ball by the stem mechanical pressure, pressure on the seat.

2 when the handwheel counterclockwise, the stem is the reverse movement, the bottom of the angular plane to disengage the ball seat.

3 stem continues to rise, and with the stem spiral groove guide pin interaction, so that the ball began to spin without friction.

4 until fully open position, the valve stem to the limit position, the ball to the full open position.

Inlet flange ball valve closing process:

1 turn the handwheel clockwise when the valve is closed, the stem begins to fall and the ball begins to rotate.

2 continue to rotate the hand wheel, the valve stem is embedded in the spiral groove on the role of the guide pin, the stem and the ball at the same time rotate 90 degrees.

3 close, the ball has no contact with the valve seat in the case of rotation of 90 degrees.

4 hand wheel rotation of the last few laps, the bottom of the valve stem to the angle of the plane mechanical wedge to the pressure of the ball, so that it is tightly pressed on the seat, to achieve full sealing.

進口法蘭球閥產品特點：

1、適應惡劣工作環境
球閥只需要用旋轉90度的操作和很小的轉動力矩就能關閉嚴密。*平等的閥體內腔為介質提供了阻力很小、直通的流道。通常認為球閥zui適宜直接做開閉使用，但近來的發展已將球閥設計成使它具有節流和控制流量之用。球閥的主要特點是本身結構緊湊，易于操作和維修，適用于水、溶劑、酸和天然氣等一般工作介質，而且還適用于工作條件惡劣的介質，如氧氣、過氧化氫、甲烷和乙烯等。球閥閥體可以是整體的，也可以是組合式的。

2、適用要求嚴格切斷工況
軌道球閥是一種比較新型的球閥類別，它有著自身結構所*的一些*性，如開關無摩擦，密封不易磨損，啟閉力矩小。這樣可減小所配執行器的規格。配以多回轉電動執行機構，可實現對介質的調節和嚴密切斷。

法蘭球閥產品之所以被廣泛使用，是因為它具有很多優點。而且隨著社會的不斷進步，產品在各方面得到質的飛躍。

Inlet flange ball valve product features:

1, to adapt to the harsh working environment

Only need to rotate the ball 90 degrees of operation and a small rotation torque can be closed tight. Full equality of the valve body cavity provides a small resistance, through the flow channel. It is generally believed that the most suitable for the use of open and close valve, but the recent development has been designed to make it a throttle valve and control the flow of use. The main features of the valve itself is compact, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be whole, it can be a combination of.

2, the requirements of strict cut-off conditions

Track ball valve is a new type of ball valve, it has its own unique advantages of the structure, such as the switch without friction, seal is not easy to wear, opening and closing torque is small. This reduces the size of the actuator. Equipped with multi turn electric actuator, which can adjust the medium and cut off tightly.

Flange ball valve products are widely used, because it has many advantages. And with the continuous progress of the society, the product has been a qualitative leap in all aspects.
