進口氣動快關斷閥產品概述:

執行器是控制系統的終端控制元件，是重要的環節，氣動調節閥在常用的執行器中約占85﹪以上。控制系統中因氣動調節閥造成不能投運或運行不良者有占50﹪-60﹪以上。其中除提供的工藝參數出入較大，閥制造質量欠佳和使用不當外，選型與計算的方法不妥則是一個相當突出的因素。因此，如何合理正確地選擇和計算氣動調節閥就是自控設計中至關重要的問題了。

調節閥按調節儀表的控制信號，直接調節流體的流量，在控制系統中起著十分重要的作用。要根據使用條件和用途來選擇調節閥。選擇調節閥項目有：結構型式、公稱通經、壓力－溫度等級、管道連接、上閥蓋型式、流量特性、材料及執行機構等。深入研究各個項目和它們之間的相互關系，是極其重要的。

Imported pneumatic quick closing valve product overview:

The actuator is the terminal control elements, is one of the important parts in the pneumatic valve actuator used in about 85 percent and above. Control system for pneumatic valve can not be caused by the operation or improper operation of a 50 -60%% above. Among them, in addition to providing a large number of process parameters, poor quality and improper use of the valve, the selection and calculation of the wrong method is a very prominent factor. Therefore, how to select and calculate the pneumatic valve is the most important problem in the automatic control design.

The regulating valve regulates the flow of the fluid directly according to the control signal of the adjusting instrument, which plays a very important role in the control system. According to the conditions of use and use to select the control valve. Selection of control valve project are: structure, nominal pressure, temperature grade, pipe connection, valve cover type, flow characteristics, materials and actuators. It is very important to study the relationship between the projects and the relationship between them.

進口氣動快關斷閥工作原理:

進口氣動快速切斷閥是自動化系統中執行機構的一種，由多彈簧氣動薄膜執行機構或浮動式活塞執行機構與球閥組成，接收調節儀表的信號，控制工藝管道內流體的切斷、接通或切換。通用閥門系列具有結構簡單，反應靈敏，動作可靠等特點。 可廣泛地應用在石油、化工、冶金等工業生產部門。氣動切斷閥的氣源要求經過濾的壓縮空氣，流經閥體內的介質應該是無雜質和無顆粒的液體和氣體。
1、閥門在日常工作中處于常開狀態，電磁閥線圈處于斷電狀態，不消耗電能。
2、當事故發生時，閥門線圈瞬時通電，觸發閥門快速關閉，進入自鎖狀態。此時即使撤去電源，閥門仍處于自鎖狀態，不會重新自動打開。
3、閥門采用O型閥芯結構，全焊接球閥系列開啟輕松，啟閉迅速。
4、當工作人員處理完事故，人工重新開啟閥門，才會恢復供氣。 注：根據客戶要求也可提供斷電關閉的常閉型快速切斷閥。
氣動快速切斷閥是新型的燃氣管道工程的安全配套裝置，主要應用于以下場合：
1、與可燃氣體泄漏監測儀器聯接，當儀器檢測到可燃氣體泄漏時，自動快速關閉主供氣閥門，切斷燃氣的供給，及時制止惡性事故的 發生。
2、與熱力設備的極限溫度(壓力)安全控制器聯接，當設備內檢測點的溫度(壓力)超過設定的極限數值時，自動快速關閉供氣閥門，停止燃料的供給。
3、與高層建筑的*消防報警系統聯接，當大廈發生火警時，自動切斷大廈內的燃氣供應，防止煤氣爆炸的發生。

The working principle of imported pneumatic quick shutoff valve:

Imported pneumatic quick shut-off valve is an actuator automation system, by the multi spring pneumatic diaphragm actuator or floating piston actuator and ball valve components, adjust the instrument to receive the signal, the control process pipeline fluid cut-off, turn on or switch. General valve series has the characteristics of simple structure, sensitive response, reliable action and so on. Can be widely used in petroleum, chemical, metallurgical and other industrial sectors. Pneumatic shut-off valve of the gas source through the filtered compressed air, flowing through the valve body of the media should be no impurities and no particles of liquid and gas.

1, the valve in the daily work in a normally open state, solenoid valve coil is in a state of no power consumption.

2, when the accident occurs, the valve coil instantaneous power, triggering the valve quickly closed, into the self-locking state. At this time if the power removed, the valve is still in self-locking state, not re open automatically.

3, the valve adopts O type valve core structure, all welded ball valve series open easily, open and close quickly.

4, when the staff to deal with the accident, manually re open the valve, will restore gas supply. Note: according to customer requirements can also provide power close the normally closed type quick shut-off valve.

Pneumatic quick shut-off valve is a new type of safety equipment for gas pipeline engineering:

1, and the combustible gas leakage monitoring instrument connection, when the instrument detects combustible gas leak, automatically and quickly close the main gas valve, cut off the supply of gas, time to stop the occurrence of accidents.

2, and the thermal equipment of the limit temperature (pressure) safety controller is connected, when the device detects the temperature (pressure) exceeds the set limit value, automatically close the gas valve, stop the supply of fuel.

3, with the high-rise building central fire alarm system connection, when the building fire occurs, automatically cut off the gas supply in the building, to prevent the occurrence of gas explosion.

進口氣動快關斷閥應用領域:

進口氣動快速切斷閥具有的技術性能，低負荷損失和高可靠性。適用于煤氣、天然氣及液化石油氣等可燃氣體，廣泛應用于供氣管網系統、燃氣熱能工廠車間、燃氣鍋爐房及住宅居所的安全設施。
