高压调压阀这个让人一开始想到的是阀门,开关,可是它是用来干什么的呢,其实说起来它是一个大类。最为主要的作用就是用来减压的,很好明白吧!
一般来说阀门定位器是按照力的平衡原理来设计工作的,它的工作原理就是通过杠杆的转动来设计的。当它通过波纹管的信号压力增加时,杠杆需要绕着支点转动档板靠近喷嘴。而喷嘴背压经过放大器放大后,送入薄膜执行机构气室,使的阀杆向下移动的时候就会带动反馈杆绕支点来转动,连接在同一个轴上的反馈凸轮就也跟着作逆时针的方向转动。
另一方面就是通过滚轮使杠杆绕支点来转动,并且将反馈弹簧拉伸、弹簧对杠杆的位力与信号压力作用的波纹管上的力还到力平衡的时候仪表才会到达平衡的状态。而在此时,一定的信号压力就与一定的冷门位置相对应了。而这些方式就叫做正作用,若是要改变作用方式,只要将凸轮翻转就可以了。
就简单点,高压调压阀的作用就在于调压,看着它调压的原理就基本明白是怎么回事了!
The high-pressure regulator is a valve and switch that people think of at first, but what is it for? Actually speaking, it is a big category. The most important role is to decompress, it is easy to understand!
Generally speaking, the valve positioner is designed to work according to the principle of force balance, and its working principle is designed through the rotation of the lever. When the signal pressure through the bellows increases, the lever needs to rotate the baffle around the fulcrum to approach the nozzle. After the nozzle back pressure is amplified by the amplifier, it is sent to the air chamber of the film actuator. When the valve stem moves down, it will drive the feedback rod to rotate around the fulcrum, and the feedback cam connected to the same axis will also reverse. The direction of the hour hand turns.
On the other hand, the lever is rotated around the fulcrum by the roller, and the force on the bellows acting on the feedback spring, the position force of the spring on the lever and the signal pressure, will not reach the equilibrium state until the force is balanced. At this time, a certain signal pressure corresponds to a certain unpopular position. These modes are called positive action. If you want to change the action mode, just flip the cam.
Simply put, the role of the high-pressure regulator is to regulate the pressure, and you can basically understand what is going on by looking at the principle of its pressure regulation!
