(3) In Figure 1, the bottom connecting pipe which plays the role of drainage is connected with the plug by thread. When the temperature rises, it is difficult to ensure the sealing of the threaded part, so it is decided to cancel the plug. In Figure 2, the plug connected with the bottom connecting pipe is replaced with a bench drain plug, and the connecting end is sealed with a winding gasket to ensure the sealing reliability of the bottom end.

What kind of pneumatic butterfly valve should be taken care of at home
As for parts, if we take care of them well, they will increase their service life, as well as pneumatic butterfly valves. Therefore, pneumatic butterfly valves need to be taken care of well. Next, I will introduce how pneumatic butterfly valves should be taken care of
There are many detailed methods. First of all, we need to stop clearing these products from time to time. When we find that the surface of these products once showed dirt, we can use a wet cloth to wipe it quietly, and pay attention not to use too much force, otherwise the appearance of the pneumatic butterfly valve will show scratches. It should be noted that we must not place the wet pneumatic butterfly valve in a wet environment. Although it is difficult to rust, it will inevitably lead to some quality problems in such an environment for a long time. Therefore, the storage environment of the pneumatic butterfly valve is relatively important. We should try to place it in a cool and ventilated center.
Finally, when we just used the pneumatic butterfly valve, we also need to see whether its installation steps are reasonable. The wrong installation method will directly affect its application limit. If you are a careful person, you can also re check whether its device routine is reasonable when you install the product.
