What are the advantages of fork cylinder

With the increasing demand for the fork cylinder, we also see that there are more and more manufacturers producing this equipment on the market. In this case, consumers will not know how to start when choosing and purchasing. Therefore, only if you fully understand the advantages of the fork cylinder, can it help us to choose and purchase products. Now we will give you a brief introduction.

The fork cylinder runs relatively smoothly, so the failure rate is low, the volume is small, and the service life is long. These are its advantages and are determined by its structure. During operation, the output torque can change with the change of angle. At the opening or closing position of the valve, the torque value is large, just in line with the law of the valve. Therefore, it can save more torque than rack and pinion actuator, because the torque of rack and pinion actuator is constant. However, they are all produced according to the high requirements of working conditions, and the future will be the era dominated by fork cylinders.


In order to let you buy a good fork type cylinder, you need to know that there are two main structures of the valve electric device: one is without thrust plate, which directly outputs torque; The other is equipped with a thrust plate. The output torque output thrust is converted by the valve rod nut on the thrust plate. In addition, it should be noted that the main parameters of the valve electric device need to be selected. The output torque of the pneumatic actuator shall be 1.2~1.5 times of the valve operating torque.

The operation of fork cylinder not only meets the explosion-proof requirements, but also has small size, light weight and large torque. The valve rod diameter of the fork cylinder is similar to that of the multi-turn lift valve. If the allowable large valve stem diameter of the electric device cannot pass through the valve stem of the matching valve, the electric device cannot be assembled. Therefore, the inner diameter of the hollow output shaft of the electric device needs to be greater than the outer diameter of the stem of the lift valve. In addition, we should also know that for deflection and multi-rotation non-rising stem, although the channel of stem diameter does not need to be considered, the selection of stem diameter and stem size should also take full account of the keyway, so that the assembly can work normally.

In short, the advantages of this product are that the shaft sleeve is smooth and wear-resistant, the carbon graphite filled Teflon guide point and the carbon graphite filled Teflon piston seal form a multi-point guide seal, the sealing performance is greatly improved, and the friction force is greatly reduced. At the same time, the fork cylinder plays a supporting and fixing role, which can make the piston and front fork more stable in the process of movement and extend the service life. But when buying, we also need to look for regular manufacturers. In this way, we can meet these basic advantages only if we are guaranteed in all aspects.

The above article is about the advantages of the fork type cylinder introduced by the editor, mainly about its function and function. If you don't understand it, read it quickly. I hope it can help relevant people. Thank you for reading my article.
