Application of Fisher control valve in nuclear power

The Fisher 3610JP pneumatic positioner is used in conjunction with a double-acting rotary actuator to position control valves for throttling applications. These rugged positioners provide valve position proportional to the pneumatic or DC current input signal and are mounted integrally to the actuator housing. specification ...

We often see such a scene on the steam pipeline, the pipe section that can be "straight" suddenly bent a section, I believe that many people who have seen it will have such doubts like me, this is not "painting snakes", in fact, the design of the pipeline operation has its own original...

Cavitation: When the static pressure of the liquid entering the first-class impeller in the pump is lower than or equal to the saturated vapor pressure at this temperature, the liquid vaporizes and produces bubbles. This vaporization and condensation produce ...

The vibration of the control valve is generally divided into two states, one is the overall vibration of the control valve, that is, the entire control valve frequently vibrates on the pipeline or base. The other is the vibration of the spool of the regulating valve, which can be seen from the frequent movement of the valve stem up and down, and the following are the causes of these two vibrations and their treatment Measure...

1. Interfacial leakage of mechanical seals: a kind of leakage between the surface of the sealing ring (oil seal, sealing ring, gasket, packing) and the surface of the contact parts. Such as leakage between the flange and the gasket, between the packing material and the shaft or the packing box. 2. Penetration and leakage of mechanical seals: medium ...

The opening and closing parts of the butterfly valve are butterfly plates, which are driven by the valve stem and rotate 90° around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting. It is mainly used to cut off the medium in the pipeline, with simple structure, flexible operation, fast switching, small size, short structure.

What should I pay attention to when the automatic initialization of the valve positioner is unsuccessful? DVC6200 smart valve positioners need to be initialized before they are put into use, and due to incorrect installation and use, they often run into trouble during the initialization process. place There are several aspects that need to be noted: 1 ...

In the valve design or use experience, the lifting valve packing is mostly asbestos packing or graphite packing or PTFE V-type packing, but these packings are limited by the number of valve opening and closing, that is, with the increase of the number of valve opening and closing, the packing will wear out, and the gap will gradually increase, to a certain number of times.
