The stainless steel ball valve is a compact, easy-to-maintain, and easy-to-operate valve, which relies on the rotating spool to realize the smooth flow or blockage of the valve. Next, Junkai Valve will introduce to you what are the construction requirements for stainless steel ball valves?
Wenzhou Longwan Junkai Valve Factory is located in Longwan, the valve capital of China. Is a professional manufacturer of stainless steel valves. The main products are: stainless steel ball valve, stainless steel Y-type filter, stainless steel flange, stainless steel mirror, stainless steel gate valve, stainless steel globe valve, stainless steel check valve, etc.
The construction of stainless steel ball valve mainly has the following requirements:
1. Avoid hitting stainless steel ball valves made of brittle materials during installation and construction.
2. Check the stainless steel ball valve before installation: check the specification and model, identify whether there is any damage, especially the valve stem, and turn it a few times to see if it is skewed. At the same time, the debris in the valve should be cleaned.
3. When lifting the stainless steel ball valve, do not tie the rope to the handwheel or valve stem of the stainless steel ball valve to avoid damage to the parts. The correct way is to tie it to the flange.
4. The pipeline connected to the stainless steel ball valve should be cleaned.
5. Use compressed air to blow off impurities such as iron oxide chips, sediment, welding slag, etc., to avoid scratching the sealing surface of the stainless steel ball valve, or to prevent impurities from clogging the pipe.
6. When installing the stainless steel ball valve, the sealing packing should be wrapped on the pipe thread, and it should not be put into the ball valve, so as to avoid accumulation and hinder the flow of medium.
7. When installing the stainless steel ball valve, pay attention to tightening the bolts symmetrically and evenly.
8. The stainless steel ball valve and the pipe flange must be parallel, and the gap should be reasonable to avoid cracking caused by excessive pressure. Especially for stainless steel ball valves with brittle materials and low strength, attention should be paid to the stainless steel ball valves welded with pipes, spot welding first, then fully open the closing parts, and then weld them dead.
