Analysis of advantages and disadvantages of pneumatic plug valves
Pneumatic plug valve is an instrument used in modern industry with very high frequency. The use of pneumatic plug valve not only provides great convenience for China's industry, but also promotes the further development of pneumatic plug valve. As plug valves, they also have different advantages and disadvantages due to their different types.
1. Advantages of pneumatic plug valve
Pneumatic plug valves use the latest type of lift-type tangential plug valves. They do not cause any friction during use, and the entire valve is very simple to use and will not appear. Any leak. The use of pneumatic plug valves is relatively much longer than other types of plug valves.
When the pneumatic plug valve is opened, the valve core is first moved upwards and then out of the valve. This movement is free of friction. When the valve is closed, the movement of the valve plug is counterclockwise until it turns until the valve is completely closed. The rotary table, in the entire process, the valve seat is absolutely not any friction.
2, pneumatic plug valve disadvantage
Although there will be no friction between the valve plug and the valve seat during the entire use, the friction during the use of the deck is very large, and this friction is always present, sometimes if the entire operation is If it is relatively large, it will often appear scratches on the surface of the deck and the seat seal, so that long-term movement will lead to valve leakage.
During the use of the pneumatic plug valve, there is no automatic leak detection device, even if a small valve is added to the automatic inspection leak in the subsequent installation process, but this automatic inspection The method will not exert very good results. Finally, there will be some small particles appearing in the operation of the pneumatic plug valve. This will cause the valve plug to be completely closed.
The above is the advantages and disadvantages of the pneumatic plug valve we introduced for everyone. In fact, during the use of the pneumatic plug valve, we should pay attention to whether the pneumatic plug valve has leakage problems, especially the connection process of some harmful substances. In the case of harmful substances and leaks, the harm to the human body is very great.
