進口氣動閘閥

氣動閘閥英文名稱：Pneumatic valve

氣動閘閥：借助壓縮空氣驅動的閥門。閘閥關閉時 , 密封面可以只依靠介質壓力來密封 , 即依靠介質壓力將閘板的密封面壓向另一側的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強制密封的 , 即閥門關閉時，要依靠外力強行將閘板壓向閥座 , 以保證密封面的密封性，進口氣動閘閥是具有氣動執行機構（雙層氣缸，并帶有緩沖機構）和手動及其保護機構（手動和可自鎖的氣動-手動轉換裝置）的低支架明桿閘閥。該閥由于采用雙層氣缸結構，其與單氣缸式氣動閘閥相比，提升力增大了一倍。這就從根本上解決了單氣缸氣動閘閥的某些閥體內楔死而打不開的弊病。而且，由于該閥具備緩沖機構，能有效地減速輕了關閉閥門時，由于活塞下行沖擊而造成的閥板車密封面和閥體密封面的磨損，同時，也能避免閘板卡死的現象。 

　  為了配合用戶實現操作自動化，本公司除供應本系列產品之外，還可單獨提供包括支架在內的氣缸體，幫助用戶對已有的種類繁多的手動閘閥進行改造，將雙缸氣動執行機構部分安裝在手動閘閥的閥體大蓋上，即可構成雙缸式氣動-手動兩用閘閥。 

　　由于其技術先進，性能可靠，操作切換和維修方便，已被石油、化工、冶金、電力、海運等部門作為輸送氣體、液體介質的管道開閉裝置而廣泛使用。

進口氣動閘閥產品結構特點：

德國Orsen奧爾申進口氣動閘閥(Flange Gate Valve)適用于公稱壓力CLASS150-900LBS,工作溫度-29～350℃的石油、化工、制藥、化肥、電力行業等各種工況的管路上，切斷或接通管路介質，性能安全可靠.驅動方式氣動。

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、進口氣動閘閥采用壓力自緊式結構或中部法蘭密封結構，密封分為雙閘板或彈性單閘板、剛性單閘板等三種形式，兩邊和管道連接采用焊接和法蘭兩種形式。

2、填料壓蓋和壓套分體設計，保證閥桿的同心度。合理的填料函設計，確保閥門沒有外漏，符合環保要求。閥蓋上設有油杯，可定期補充固體潤滑油，保持輕松啟閉。

3、閘閥的閥座與閥體連接是采用螺紋式連接，方便修理、更換。閥座的靜密封面經過精密研磨并用專用工具旋入閥體，實現可靠的密封。閘板密封面比閥座密封面寬出一定的余量，并保證閥門在未使用前閘板密封面底線與閥座密封面底線在同一高度，使閥門在使用一定時間后即使磨損也不會減少必須保證的密封面寬度。

4、進口氣動閘閥的閘板和閥體密封部位采用錐形結構設計，確保閥門使用長久，閥門使用越久閘板磨損越大的時候，閘板陷入閥體密封部分越多，確保密封更好。  如果您有需要求購進口氣動閘閥，了解氣動閘閥原理，氣動閘閥結構，進口氣動閘閥型號，進口氣動閘閥尺寸的需要，歡迎來電咨詢，我們將竭誠為您提供優質的產 品和服務！
