进口气动闸阀

气动闸阀英文名称：Pneumatic valve

气动闸阀：借助压缩空气驱动的阀门。闸阀关闭时 , 密封面可以只依靠介质压力来密封 , 即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。大部分闸阀是采用强制密封的 , 即阀门关闭时，要依靠外力强行将闸板压向阀座 , 以保证密封面的密封性，进口气动闸阀是具有气动执行机构（双层气缸，并带有缓冲机构）和手动及其保护机构（手动和可自锁的气动-手动转换装置）的低支架明杆闸阀。该阀由于采用双层气缸结构，其与单气缸式气动闸阀相比，提升力增大了一倍。这就从根本上解决了单气缸气动闸阀的某些阀体内楔死而打不开的弊病。而且，由于该阀具备缓冲机构，能有效地减速轻了关闭阀门时，由于活塞下行冲击而造成的阀板车密封面和阀体密封面的磨损，同时，也能避免闸板卡死的现象。 

　  为了配合用户实现操作自动化，本公司除供应本系列产品之外，还可单独提供包括支架在内的气缸体，帮助用户对已有的种类繁多的手动闸阀进行改造，将双缸气动执行机构部分安装在手动闸阀的阀体大盖上，即可构成双缸式气动-手动两用闸阀。 

　　由于其技术先进，性能可靠，操作切换和维修方便，已被石油、化工、冶金、电力、海运等部门作为输送气体、液体介质的管道开闭装置而广泛使用。

进口气动闸阀产品结构特点：

德国Orsen奥尔申进口气动闸阀(Flange Gate Valve)适用于公称压力CLASS150-900LBS,工作温度-29～350℃的石油、化工、制药、化肥、电力行业等各种工况的管路上，切断或接通管路介质，性能安全可靠.驱动方式气动。

Pneumatic valve: With compressed air driven valve. When the valve is closed, the sealing surface can only rely on media pressure to seal, which rely on the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface, imported pneumatic valve is a pneumatic actuator (double cylinder, and with buffering mechanism) and manual and Protection Agency (manual and pneumatic self-locking - Manual conversion device) Low stand clear shot valve. The valve is due to the use of double cylinder structure compared with the single cylinder pneumatic valve, the lifting force increases doubled. This solves some of the valve body the death of a single cylinder pneumatic wedge gate valve does not open from the fundamental ills. Further, since the valve includes a buffer mechanism, can effectively slow down when the light valve is closed, due to the impact caused by the piston down the valve sealing surface and the valve body dray wear the sealing surface, while also avoiding the phenomenon of death shutter plate .

In order to meet users to achieve automatic operation, the company in addition to the supply of this product, also available separately, including stents, including the cylinder block, helping users to the existing wide range of manual valve to transform part of the cylinder pneumatic actuators manual gate valve installed in large cap, can constitute a pneumatic cylinder - manual dual gate.

Because of its advanced technology, reliable performance, easy operation and maintenance switch has been petroleum, chemical, metallurgy, electric power, shipping and other departments as pipeline gas, liquid medium switchgear and widely used.

Imported pneumatic valve product structure characteristics:

Germany imported pneumatic valve Shen Orsen Orr (Flange Gate Valve) for nominal pressure CLASS150-900LBS, pipeline operating temperature petroleum, chemical, pharmaceutical, fertilizer, power industry -29 ~ 350 ℃ of other working conditions, cut or connected to the line media, safe and reliable performance. Drive Pneumatic.

1、进口气动闸阀采用压力自紧式结构或中部法兰密封结构，密封分为双闸板或弹性单闸板、刚性单闸板等三种形式，两边和管道连接采用焊接和法兰两种形式。

2、填料压盖和压套分体设计，保证阀杆的同心度。合理的填料函设计，确保阀门没有外漏，符合环保要求。阀盖上设有油杯，可定期补充固体润滑油，保持轻松启闭。

3、闸阀的阀座与阀体连接是采用螺纹式连接，方便修理、更换。阀座的静密封面经过精密研磨并用专用工具旋入阀体，实现可靠的密封。闸板密封面比阀座密封面宽出一定的余量，并保证阀门在未使用前闸板密封面底线与阀座密封面底线在同一高度，使阀门在使用一定时间后即使磨损也不会减少必须保证的密封面宽度。

4、进口气动闸阀的闸板和阀体密封部位采用锥形结构设计，确保阀门使用长久，阀门使用越久闸板磨损越大的时候，闸板陷入阀体密封部分越多，确保密封更好。  如果您有需要求购进口气动闸阀，了解气动闸阀原理，气动闸阀结构，进口气动闸阀型号，进口气动闸阀尺寸的需要，欢迎来电咨询，我们将竭诚为您提供优质的产 品和服务！
