不锈钢电动球阀概述是一种转角为90°的旋转类阀门,密封性能优良,流量系数大,流阻系数小,结构简单,使用寿命长,便于维修。配用气缸式执行机构,电动球阀分开关式和调节式两种型号。产品广泛应用于化工、石油、轻纺、电力、食品制药、制冷、造纸行业的系统控制。法兰连接的管路能保持良好密封性能，便于维修更换，便于管路的封闭.

■流体阻力小、球阀是所有阀类中流体阻力最小的一种，即使是缩径球阀，其流体阻力也相当小。
■止推轴承减小阀杆摩擦力矩，可使阀杆长期操作平衡灵活。
■阀座密封性能好，采用聚四氟乙烯等材料制成的密封圈，结构易于密封，而且球阀的阀封能力随着介质压力的增设而增大。
■阀杆密封可靠，由于阀杆只作旋***动而不做升降运动，阀杆的填料密封不易破坏，且密封能力随着介质的压力增设而增大。
■由于聚四氟乙烯等材料具有良好的自润滑性，与球体的摩擦损失小，帮球阀的使用寿命长。
■下装式阀杆和阀杆头部凸阶防止阀杆喷出，如火灾造成阀杆密封破坏，凸阶与阀体间还可形成金属接触，确保阀杆密封。

Summary of stainless steel electric ball valve is a kind of Angle is 90 ° rotation type valves, sealed performance is good, flow coefficient, flow resistance coefficient is small, simple structure, long service life and easy maintenance. With cylinder actuators, electric ball valve shuts off and adjust the two models. Products are widely used in chemical, petroleum, textile, electricity, food, pharmaceutical, refrigeration, control system in papermaking industry. Flange connection line can maintain good sealing performance, easy replacement of maintenance, facilitate line closed.

S small fluid resistance, ball valve is the smallest of all valve fluid resistance in the class a, even reducing ball valve, the fluid resistance is small.

S thrust bearings reduce stem friction torque, can make the valve stem long flexible operating balance.

S seat sealing performance is good, use the materials such as ptfe sealing ring, the structure is easy to be sealed, and ball valve valve sealing ability increases with the adding of medium pressure.

S stem seal is reliable, because of the valve rod rotation movement and not only do the lifting movement, the valve stem packing seal is not easy to damage, and sealing ability increase with the pressure increasing and medium.

S such as ptfe material has good self-lubrication, and small sphere of the friction loss, help ball valve&＃39;s service life is long.

S bottoms type valve stem and valve stem head convex order prevent stem, stem seal damage caused by such as fire, convex order between the body and also can form metal contact, to ensure that the valve stem seal.
