旋启式止回阀又称止回阀，其作用是防止流体在管道中回流。为防止流体回流，阀瓣由流体流动强度自动开启或关闭。止回阀属于自动阀，主要用于单向流动的流体管道上，为防止事故发生，它只允许流体单向流动，这种阀门通常水平安装在管道上。

产品特点：

1、旋启式止回阀为自密封阀。阀瓣可由流体作用，防止介质回流。

2、带弹簧的阀瓣可以使阀门在任何方向上工作。

3、结构合理，密封可靠，性能优良，外形美观，是制造英国卡麦隆阀门的关键。

4、旋启式阀瓣，过流式，可安装水平管道立管。

5、摇臂销轴采用加载式结构，减少外部泄漏故障。

6、阀盖螺栓连接，高压等级大于600Lb级，法兰压力来自密封结构，制造产品。

7、体积轻，密封可靠。标准（防火、防静电）。

选择与使用：

为防止介质倒流，在设备、装置和管道上安装旋启式止回阀，止回阀一般适用于清洗介质，不适用于固体颗粒和高粘度介质，旋启式止回阀的安装位置不受限制。它可以安装在水平、垂直或倾斜的管道上。如果安装在垂直管道上，介质的流向应自下而上DN大于50 mm小于600 mm的高中压止回阀应选用旋启式止回阀。

英国(UKCAMERON)卡麦隆国际集团是欧州流体控制领域的主要生产和供应商之一，公司总部位于英国英格兰，公司致力于科研开发，生产流体控制设备系统，在许多个国家均有生产基地。其产品远销世界各国 ，在世界200多个地区均有代理商。英国Cameron国际集团主要产品有：进口电动球阀、进口电动蝶阀、进口气动蝶阀、进口气动球阀、进口截止阀、进口电磁阀、进口疏水阀等一系列工业上常用配件。

进口电动球阀是一种转角90°的旋转类球阀， 流体阻力小、球阀是所有发类中流体阻力 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，可使用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的压力增大而增大。阀杆密封可靠，由于阀杆只做旋转运动而不是升降运动，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，如果火灾造成阀杆密封破坏，凸阶与阀体间还可以形成金属接触，确保阀杆密封配用ODL、OHQ等高性能执行机构、产品通常用于密封要求严格的场合，除控制气体、液体、蒸汽介质外，还适宜控制污水和含有纤维性杂质的介质，广泛用于石油、化工、冶金、轻工、造纸、电站、制冷等工作领域。

Description of imported Electric Flanged Ball Valves

UKCAMERON International Group is one of the main producers and suppliers in the field of fluid control in Europe. Its headquarters is in England, UK. The company is committed to scientific research and development, and produces fluid control equipment systems. It has production bases in many countries. Its products are sold all over the world and have agents in more than 200 regions of the world. Cameron International Group's main products are: imported electric ball valves, imported electric butterfly valves, imported pneumatic butterfly valves, imported pneumatic ball valves, imported globe valves, imported solenoid valves, imported traps and a series of commonly used industrial accessories.

imported electric ball valve is a kind of rotary ball valve with 90 degrees rotation angle. The fluid resistance of the ball valve is the smallest among all kinds of ball valves. Even the shrink ball valve, its fluid resistance is quite small. Thrust bearing reduces the friction moment of the valve stem, and can use the valve stem for long-term operation, balance and flexibility. Seat sealing performance is good. The sealing ring made of PTFE and other materials is easy to seal, and the sealing capacity of the ball valve increases with the increase of medium pressure. Stem sealing is reliable. Because the stem only rotates rather than lifts, the packing seal of the stem is not easy to be damaged, and the sealing ability increases with the increase of medium pressure. Because PTFE material has good self-lubrication, small friction loss with the sphere, and long service life of the ball-help valve. Bottom-mounted stem and convex step of stem head prevent stem from ejecting. If fire causes stem seal damage, metal contact can also be formed between convex step and valve body. It ensures that high-performance actuators such as ODL and OHQ are used for stem seal, and products are usually used in situations with strict sealing requirements. Besides controlling gas, liquid and steam medium, sewage and media containing fibrous impurities are also suitable for control. Quality, widely used in petroleum, chemical industry, metallurgy, light industry, papermaking, power plants, refrigeration and other fields.
