1. Introduction:

The two-piece ball valve is a relatively new type of ball valve. It has some of the characteristics of its own structure: the switch is frictionless, the seal is not easy to wear, and the opening and closing torque is small. This can reduce the size of the actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and close shut-off of the medium. It is widely used in working conditions that require strict cut-off such as petroleum, chemical industry, and urban water supply and drainage. It is to make the valve unblocked or blocked by rotating the valve. The two-piece ball valve switch is light, small in size, can be made into a large diameter, reliable in sealing, simple in structure and convenient in maintenance. The sealing surface and the spherical surface are often closed and are not easily eroded by the medium. It is widely used in various industries.

二、特點(diǎn)：
1、流體阻力小，其阻力系數(shù)與同長度的管段相等。
2、結(jié)構(gòu)簡單、體積小、重量輕。
3、緊密可靠，目前球閥的密封面材料廣泛使用塑料、密封性好，在真空系統(tǒng)中也已廣泛使用。
4、操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90°，便于遠(yuǎn)距離的控制。
5、維修方便，球閥結(jié)構(gòu)簡單，密封圈一般都是活動(dòng)的，拆卸更換都比較方便。
6、在全開或全閉時(shí)，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時(shí)，不會引起閥門密封面的侵蝕。
7、適用范圍廣，通徑從小到幾毫米，大到幾米，從高真空至高壓力都可應(yīng)用。 球旋轉(zhuǎn)90度時(shí)，在進(jìn)、出口處應(yīng)全部呈現(xiàn)球面，從而截?cái)嗔鲃?dòng)。

2. Features:

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.

2. Simple structure, small size and light weight.

3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics with good sealing performance, and it has also been widely used in the vacuum system.

4. Convenient operation, rapid opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for remote control.

5. Convenient maintenance, simple structure of the ball valve, generally movable sealing ring, easy to disassemble and replace.

6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.

7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should show a spherical surface at the entrance and exit, so as to cut off the flow.

三、結(jié)構(gòu)特點(diǎn)：
1、啟閉無摩擦。這一功能完了傳統(tǒng)閥門因密封面之間相互摩擦而影響密封的問題。
2、上裝式結(jié)構(gòu)。對裝在管道上的閥門可直接在線檢查與維修，能有效減少裝置停車，降低成本。
3、單閥座設(shè)計(jì)。消除了閥門中腔介質(zhì)因異常升壓而影響使用安全的問題。
4、低扭矩設(shè)計(jì)。特殊結(jié)構(gòu)設(shè)計(jì)的閥桿，只需配一個(gè)小手把閥門就能輕松啟閉。
5、楔形密封結(jié)構(gòu)。閥門是靠閥桿提供的機(jī)械力，將球楔壓到閥座上而密封，使閥門的密封性不受管線壓差變化的影響，在各種工況下密封性能都有可靠保證。
6、密封面的自清潔結(jié)構(gòu)。當(dāng)球體傾離閥座時(shí)，管線中的流體沿球體密封面成360°均勻通過，不僅消除了高速流體對閥座局部的沖刷，也沖走了密封面上的聚積物，達(dá)到自清潔的目的。

3. Structural features:

1. There is no friction when opening and closing. This function eliminates the problem of traditional valves affecting the sealing due to mutual friction between the sealing surfaces.

2. Top-mounted structure. The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce device shutdown and reduce costs.

3. Single valve seat design. Eliminates the problem that the medium in the valve cavity affects the safety of use due to abnormal pressure increase.

4. Low torque design. The valve stem with special structure design can easily open and close the valve with only a small handle.

5. Wedge-shaped sealing structure. The valve is sealed by the mechanical force provided by the valve stem to press the ball wedge onto the valve seat, so that the sealing performance of the valve is not affected by the change of pipeline pressure, and the sealing performance is reliably guaranteed under various working conditions.

6. Self-cleaning structure of the sealing surface. When the ball tilts away from the valve seat, the fluid in the pipeline passes through the ball sealing surface at 360° uniformly, which not only eliminates the local washing of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning .
