一、概述Outline：
氣動信號球閥主要用于截斷或接通管路中的介質，亦可用用于流體的調節(jié)與控制，它與其它閥類相比，具有以下一些優(yōu)點。

1、流體阻力小、球閥是所有閥類中流體阻力最小的一種，即使是縮徑球閥，其流體阻力也相當小。
2、止推軸承減小閥桿磨擦力矩，可使閥桿長期操作平穩(wěn)靈活。
3、閥座密封性能好，采用聚四氟乙烯等彈性材料制成的密封圈，結構易于密封，而且球閥的閥封能力隨著介質壓力的增高而增大。
4、閥桿密封可靠，由于閥桿只作彷轉動運而不做升降運動，閥桿的填料密封不易破壞，且密封能力隨著介質的壓力增高而增大。
5、由于聚四氟乙烯等材料具有良好的自潤滑性，與球體的磨擦損失小，故球閥的使用壽命長。
6、下裝式閥桿和閥桿頭部凸階防止閥桿噴出，如火災造成閥桿密封破壞，凸階與閥體間還可形成金屬接觸，確保閥桿密封。
7、 防靜電功能：在球體、閥桿、閥體之間設置彈簧，能將開關過程產生的靜電導出。 執(zhí)行機構

Pneumatic valve is mainly used for truncation or signal line connected to the media, can also be used for fluid regulation and control, it is compared with other valves, has the following advantages.

1, fluid resistance, ball valves in all a fluid path of least resistance, even reduced diameter valve, the fluid resistance is quite small.
2, stem thrust bearing reduces friction torque, smooth operation can stem the long-term flexibility.
3, the valve seat sealing performance, the use of PTFE seals and other flexible materials, structure easy to seal, and the ability with the ball valve closure increased with increasing media pressure.
4, valve stem seals and reliable, due to stem not only do the operation for turning down imitation of movement, stem packing seal is not easy to destroy, ａnd the sealing ability increased with the increase of the pressure medium.
5, the PTFE and other materials with good self-lubrication, the friction loss with the ball, so the ball＇s long life.
6, download style stem and stem spray head convex order to prevent the stem, causing stem seal damage such as fire, convex order and the body can be formed between the metal contact, to ensure that the valve stem seals.
7, anti-static function: the ball, stem, between the valve spring set, static electricity generated by the switching process can export. Executive body.
