進(jìn)口氣動快關(guān)斷閥產(chǎn)品概述:

執(zhí)行器是控制系統(tǒng)的終端控制元件，是重要的環(huán)節(jié)，氣動調(diào)節(jié)閥在常用的執(zhí)行器中約占85﹪以上?？刂葡到y(tǒng)中因氣動調(diào)節(jié)閥造成不能投運(yùn)或運(yùn)行不良者有占50﹪-60﹪以上。其中除提供的工藝參數(shù)出入較大，閥制造質(zhì)量欠佳和使用不當(dāng)外，選型與計(jì)算的方法不妥則是一個相當(dāng)突出的因素。因此，如何合理正確地選擇和計(jì)算氣動調(diào)節(jié)閥就是自控設(shè)計(jì)中至關(guān)重要的問題了。

調(diào)節(jié)閥按調(diào)節(jié)儀表的控制信號，直接調(diào)節(jié)流體的流量，在控制系統(tǒng)中起著十分重要的作用。要根據(jù)使用條件和用途來選擇調(diào)節(jié)閥。選擇調(diào)節(jié)閥項(xiàng)目有：結(jié)構(gòu)型式、公稱通經(jīng)、壓力－溫度等級、管道連接、上閥蓋型式、流量特性、材料及執(zhí)行機(jī)構(gòu)等。深入研究各個項(xiàng)目和它們之間的相互關(guān)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(jìn)口氣動快關(guān)斷閥工作原理:

進(jìn)口氣動快速切斷閥是自動化系統(tǒng)中執(zhí)行機(jī)構(gòu)的一種，由多彈簧氣動薄膜執(zhí)行機(jī)構(gòu)或浮動式活塞執(zhí)行機(jī)構(gòu)與球閥組成，接收調(diào)節(jié)儀表的信號，控制工藝管道內(nèi)流體的切斷、接通或切換。通用閥門系列具有結(jié)構(gòu)簡單，反應(yīng)靈敏，動作可靠等特點(diǎn)。 可廣泛地應(yīng)用在石油、化工、冶金等工業(yè)生產(chǎn)部門。氣動切斷閥的氣源要求經(jīng)過濾的壓縮空氣，流經(jīng)閥體內(nèi)的介質(zhì)應(yīng)該是無雜質(zhì)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(tài)，電磁閥線圈處于斷電狀態(tài)，不消耗電能。
2、當(dāng)事故發(fā)生時，閥門線圈瞬時通電，觸發(fā)閥門快速關(guān)閉，進(jìn)入自鎖狀態(tài)。此時即使撤去電源，閥門仍處于自鎖狀態(tài)，不會重新自動打開。
3、閥門采用O型閥芯結(jié)構(gòu)，全焊接球閥系列開啟輕松，啟閉迅速。
4、當(dāng)工作人員處理完事故，人工重新開啟閥門，才會恢復(fù)供氣。 注：根據(jù)客戶要求也可提供斷電關(guān)閉的常閉型快速切斷閥。
氣動快速切斷閥是新型的燃?xì)夤艿拦こ痰陌踩涮籽b置，主要應(yīng)用于以下場合：
1、與可燃?xì)怏w泄漏監(jiān)測儀器聯(lián)接，當(dāng)儀器檢測到可燃?xì)怏w泄漏時，自動快速關(guān)閉主供氣閥門，切斷燃?xì)獾墓┙o，及時制止惡性事故的 發(fā)生。
2、與熱力設(shè)備的極限溫度(壓力)安全控制器聯(lián)接，當(dāng)設(shè)備內(nèi)檢測點(diǎn)的溫度(壓力)超過設(shè)定的極限數(shù)值時，自動快速關(guān)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(tǒng)聯(lián)接，當(dāng)大廈發(fā)生火警時，自動切斷大廈內(nèi)的燃?xì)夤?yīng)，防止煤氣爆炸的發(fā)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.
