进口法兰球阀工作原理：
进口法兰球阀开启过程：
1在关闭位置，球体受阀杆的机械施压作用，紧压在阀座上。
2当逆时针转动手轮时，阀杆则反向运动，其底部角形平面使球体脱开阀座。
3阀杆继续提升，并与阀杆螺旋槽内的导销相互作用，使球体开始无摩擦地旋转。
4直至到全开位置，阀杆提升到极限位置，球体旋转到全开位置。
进口法兰球阀关闭过程：
1关闭时，顺时针旋转手轮，阀杆开始下降并使球体离开阀座开始旋转。
2继续旋转手轮，阀杆受到嵌于其上螺旋槽内的导销的作用，使阀杆和球体同时旋转90°。
3 快要关闭时，球体已在与阀座无接触的情况下旋转了90°。
4手轮转动的zui后几圈，阀杆底部的角形平面机械地楔向压迫球体，使其紧密地压在阀座上，达到*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.
进口法兰球阀产品特点：
1、适应恶劣工作环境
球阀只需要用旋转90度的操作和很小的转动力矩就能关闭严密。*平等的阀体内腔为介质提供了阻力很小、直通的流道。通常认为球阀zui适宜直接做开闭使用，但近来的发展已将球阀设计成使它具有节流和控制流量之用。球阀的主要特点是本身结构紧凑，易于操作和维修，适用于水、溶剂、酸和天然气等一般工作介质，而且还适用于工作条件恶劣的介质，如氧气、过氧化氢、甲烷和乙烯等。球阀阀体可以是整体的，也可以是组合式的。
2、适用要求严格切断工况
轨道球阀是一种比较新型的球阀类别，它有着自身结构所*的一些*性，如开关无摩擦，密封不易磨损，启闭力矩小。这样可减小所配执行器的规格。配以多回转电动执行机构，可实现对介质的调节和严密切断。
法兰球阀产品之所以被广泛使用，是因为它具有很多优点。而且随着社会的不断进步，产品在各方面得到质的飞跃。
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.
