气动信号球阀  的详细介绍

一、概述Outline:
气动信号球阀主要用于截断或接通管路中的介质,亦可用用于流体的调节与控制,它与其它阀类相比,具有以下一些优点。

1、流体阻力小、球阀是所有阀类中流体阻力蕞小的一种,即使是缩径球阀,其流体阻力也相当小。
2、止推轴承减小阀杆磨擦力矩,可使阀杆长期操作平稳灵活。
3、阀座密封性能好,采用聚四氟乙烯等弹性材料制成的密封圈,结构易于密封,而且球阀的阀封能力随着介质压力的增高而增大。
4、阀杆密封可靠,由于阀杆只作彷转动运而不做升降运动,阀杆的填料密封不易破坏,且密封能力随着介质的压力增高而增大。
5、由于聚四氟乙烯等材料具有良好的自润滑性,与球体的磨擦损失小,故球阀的使用寿命长。
6、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。
7、 防静电功能:在球体、阀杆、阀体之间设置弹簧,能将开关过程产生的静电导出。 执行机构

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.


采用新型系列GT型气动执行器,有双作用式和单作用式(弹簧复位),齿轮齿条传动,安全可靠;大口径阀门采用系列AW型气动执行器拔叉式传动,结构合理,输出扭矩大,有双作用式和单作用式。

1、齿轮式双活塞,输出力矩大,体积小。
2、气缸选用铝金材料,重量轻、外形美观。
3、可在顶部、底部安装手动操作机构。
4、齿条式连接可调节开启角度、额定流量。
5、执行器可选带电讯号反馈指示及各类附件以实现自动化操作。
6、IS05211标准连接为产品的安装更换提供了方便。
7、两端调的节螺钉可使标准产品在0°和90°有±4°的可调范围。确保与阀门的同步精度。 

附件的选项 
根据不同控制和要求可选择下列附件:
切断型附件:单电控电磁阀、双电控电磁阀、限位开关回讯器。
调节型附件:电气定位器、气动定位器、电气转换器。
气源处理附件:空气过滤减压阀、气源处理三联件。
手动机构:HVSD手操机构 
 

Using the new series of GT type pneumatic actuator, a double-acting and single acting (spring return), rack and pinion drive, safe and reliable; AW series of large diameter valves using pneumatic actuator fork-type transmission, reasonable structure, output torque, a double-acting and single acting.

1, dual-piston gear, the output torque, small size.
2, cylinder aluminum alloy materials used, light weight, beautiful appearance.
3, can be at the top, the bottom of the installation manual operating mechanism.
4, the rack can be adjusted opening angle connection, the rated flow.
5, optional electric actuator feedback signal instructions and all kinds of accessories in order to achieve automation.
6, IS05211 standard connection for the installation of the product provides a convenient replacement.
7, both ends of the section of the screw can adjust the standard products in the 0 ° and 90 ° with ± 4 ° of adjustable range. Ensure the accuracy of synchronization with the valve.

Attachment options
Control and can choose according to different requirements of the following accessories:
Cut-off accessories: single electric solenoid valve, double solenoid valve, limit switch back to the hearing.
Regulated accessories: electrical positioner, pneumatic positioners, electric converter.
Air treatment accessories: air filter regulator, air source treatment FRL.
Manual institutions: HVSD HART agencies
