The stainless steel ball valve is made to be unblocked or blocked by rotating the valve core. The valve only needs to be rotated 90° and can be closed tightly with a small rotating torque, which is easy to operate and maintain. Stainless steel ball valves are widely used in petroleum, chemical, power generation, paper making, atomic energy, aviation, rocket and other industries.
Before installing the stainless steel ball valve, we need to know some details in advance, so that we can make fewer mistakes during operation and will not affect subsequent use. Let’s talk about the installation precautions of stainless steel ball valves:
1. Before installation, check the stainless steel ball valve, check its specifications and models, and identify whether there is any damage, especially the valve stem. And remove the sundries in the valve.
2. The pipeline connected to the stainless steel ball valve must be cleaned.
3. Compressed air can be used to blow away iron oxide chips, welding slag and other sundries. Because these dirt will not only scratch the sealing surface of the stainless steel ball valve, but also large particles of debris (such as welding slag) will easily block the stainless steel ball valve and make it invalid.
4. During installation, the sealing packing (line hemp plus lead oil or polytetrafluoroethylene raw material tape) should be wrapped on the pipe thread, and should not get into the stainless steel ball valve, so as not to accumulate in the valve and affect the flow of the medium.
5. Careful attention must be paid to the installation and construction process, and the stainless steel ball valve made of brittle materials should not be hit by all means.
6. When installing, pay attention to tighten the bolts symmetrically and evenly.
7. When lifting, the rope should not be tied to the handwheel or valve stem of the stainless steel ball valve, so as not to damage its parts, it should be tied to the flange.
These trivial details have a direct impact on the installation and use of stainless steel ball valves, so more attention should be paid to them.
