产品概述:
执行器是控制系统的终端控制元件，是重要的环节，气动调节阀在常用的执行器中约占85﹪以上。控制系统中因气动调节阀造成不能投运或运行不良者有占50﹪-60﹪以上。其中除提供的工艺参数出入较大，阀制造质量欠佳和使用不当外，选型与计算的方法不妥则是一个相当突出的因素。因此，如何合理正确地选择和计算气动调节阀就是自控设计中至关重要的问题了。
调节阀按调节仪表的控制信号，直接调节流体的流量，在控制系统中起着十分重要的作用。要根据使用条件和用途来选择调节阀。选择调节阀项目有：结构型式、公称通经、压力－温度等级、管道连接、上阀盖型式、流量特性、材料及执行机构等。深入研究各个项目和它们之间的相互关系，是极其重要的。
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.
工作原理:
进口气动快速切断阀是自动化系统中执行机构的一种，由多弹簧气动薄膜执行机构或浮动式活塞执行机构与球阀组成，接收调节仪表的信号，控制工艺管道内流体的切断、接通或切换。通用阀门系列具有结构简单，反应灵敏，动作可靠等特点。 可广泛地应用在石油、化工、冶金等工业生产部门。气动切断阀的气源要求经过滤的压缩空气，流经阀体内的介质应该是无杂质和无颗粒的液体和气体。
1、阀门在日常工作中处于常开状态，电磁阀线圈处于断电状态，不消耗电能。
2、当事故发生时，阀门线圈瞬时通电，触发阀门快速关闭，进入自锁状态。此时即使撤去电源，阀门仍处于自锁状态，不会重新自动打开。
3、阀门采用O型阀芯结构，全焊接球阀系列开启轻松，启闭迅速。
4、当工作人员处理完事故，人工重新开启阀门，才会恢复供气。 注：根据客户要求也可提供断电关闭的常闭型快速切断阀。
气动快速切断阀是新型的燃气管道工程的安全配套装置，主要应用于以下场合：
1、与可燃气体泄漏监测仪器联接，当仪器检测到可燃气体泄漏时，自动快速关闭主供气阀门，切断燃气的供给，及时制止恶性事故的 发生。
2、与热力设备的极限温度(压力)安全控制器联接，当设备内检测点的温度(压力)超过设定的极限数值时，自动快速关闭供气阀门，停止燃料的供给。
3、与高层建筑的*消防报警系统联接，当大厦发生火警时，自动切断大厦内的燃气供应，防止煤气爆炸的发生。
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.
应用领域:
进口气动快速切断阀具有的技术性能，低负荷损失和高可靠性。适用于煤气、天然气及液化石油气等可燃气体，广泛应用于供气管网系统、燃气热能工厂车间、燃气锅炉房及住宅居所的安全设施。
