进口气动阀门-德国莱克LIK品牌原装进口气动阀

德国(LIK)莱克品牌:进口气动阀门是工业管道系统自动化的一种重要装置，是在普通阀门的基础上安装气动执行器，通过气源压力驱动执行器工作。从阀门的运动方式一般分为：直行程与角行程；从执行器一般分为：单作用与双作用。气动阀门通过输出信号实现阀门的切断、接通、调节等功能，一般气动阀门都配置电磁阀、气源三联件、限位开关、定位器等配件一起使用。

气动阀门定位器是按力平衡原理设计工作的，其工作原理是按力平衡原理设计和工作的。当通入波纹管的信号压力增加时，使杠杆2绕支点转动，档板靠近喷嘴，喷嘴背压经放大器放大后，送入薄膜执行机构气室，使阀杆向下移动，并带动反馈杆（摆杆）绕支点转动，连接在同一轴上的反馈凸轮（偏心凸轮）也跟着作逆时针方向转动，通过滚轮使杠杆1绕支点转动，并将反馈弹簧拉伸、弹簧对杠杆2的拉力与信号压力作用在波纹管上的力达到力矩平衡时仪表达到平衡状态。此时，一定的信号压力就与一定的阀门位置相对应。 以上作用方式为正作用，若要改变作用方式，只要将凸轮翻转，A向变成B向等，即可。 所谓正作用定位器，就是信号压力增加，输出压力亦增加；所谓反作用定位器，就是信号压力增加，输出压力则减少。 一台正作用执行机构只要装上反作用定位器，就能实现反作用执行机构的动作；相反，一台反作用执行机构只要装上反作用定位器，就能实现正作用执行机构的动作。

Pneumatic valve is an important device for the automation of industrial piping system. It is used to install pneumatic actuator on the basis of ordinary valve and drive the actuator by air source pressure. The movement mode of valve is generally divided into direct stroke and angular stroke. From the executor generally divides into: single action and double action. Pneumatic valve by the output signal is cut off and on, adjust the valve function, general pneumatic valves are electromagnetic valves, gas source sanlian pieces, limit switch, fittings such as locator.

Pneumatic valve positioner is designed and operated according to the principle of force balance. When going into the corrugated pipe pressure signal increases, the lever 2 turn around the fulcrum, dampers near the nozzle, the nozzle back pressure after the amplifier amplification, into thin film actuator air chamber, the stem moves down, and turns feedback pole (beam) around the fulcrum, feedback connection on the same shaft CAM (eccentric CAM) followed a counterclockwise rotation, through the roller to rotate the lever 1 around the pivot, and will feedback spring drawing, spring tension and pressure signal of lever 2 forces acting on the corrugated pipe reaches moment balance instrument to reach equilibrium. At this point, a certain signal pressure corresponds to a certain valve position. Above action mode is positive action, if want to change action mode, as long as turn over CAM, A direction becomes B direction to wait, can. The so-called positive function localizer, is the signal pressure increases, the output pressure also increases; The so-called reaction locator, is the signal pressure increases, the output pressure decreases. As long as a positive action actuator is installed with the reaction locator, the action of the reaction actuator can be realized. On the contrary, a reaction actuator can realize the action of a positive action actuator by installing a reaction locator.

气动阀的构成 
主要由气动执行器，阀门两大主要部分组成，当然，根据工况条件和用户的需求不同，还可选配不同的附件来实现不同的功能，如电磁阀、气源三联件、回讯器、电气定位器等。 

气动执行器分类 
从转动方式分为：直行程、角行程两种；从结构分为：活塞式、膜片式、柱塞式、叶片式等；从功能作用又分为：单作用、双作用、三位式等。 

双作用式工作原理（LIK） 
当气源压力从气口（2）进入气缸两活塞之间中腔时，使两活塞分离向气缸两端方向移动，两端气腔的空气通过气口（4）排出，同时使两活塞齿条同步带动输出轴（齿轮）逆时针方向旋转。反之气源压力从气口（4）进入气缸两端气腔时，使两活塞向气缸中间方向移动，中间气腔的空气通过气口（2）排出，同时使两活塞齿条同步带动输出轴（齿轮）顺时针方向旋转。（如果把活塞相对反方向安装，输出轴变为反向旋转，即为双作用反转型。）

Composition of pneumatic valves

Mainly by pneumatic actuators and valves of two main parts, of course, according to different working conditions and the needs of users, can also be equipped with different attachments to implement different functions, such as solenoid valves, gas source sanlian pieces, back - device, such as electrical locator.

Pneumatic actuator classification

The rotation mode can be divided into two types: direct stroke and angular stroke. The structure is divided into piston type, diaphragm type, plunger type and blade type. It can be divided into single action, double action and three - way function.

Principle of dual operation (LIK)

When the air pressure from the port (2) into the cylinder between the pistons lumen, separate the two piston to move on both ends of the cylinder, gas cavity on both ends of the air through the intake (4), at the same time to synchronize two piston rack drives the output shaft (gear) counterclockwise. And air pressure from the port (4) into the chamber on both ends of the cylinder, the two direction among the piston to the cylinder, the air cavity in the middle of the air through the intake (2), at the same time to synchronize two piston rack drives the output shaft rotate clockwise (gear). (if the piston is installed in the opposite direction, the output axis will turn into reverse rotation, that is, double action reverse transformation.)
