The stainless steel ball valve is made of stainless steel and has strong corrosion resistance. The stainless steel ball valve is equipped with a handle, which is convenient for turning the valve core in the stainless steel valve body. Due to the irregular structure of the stainless steel valve body and the handle, it is difficult to place the stainless steel valve neatly in the storage container, which easily leads to the space in the storage container not being fully utilized. Therefore, it is necessary to design a stainless steel ball valve that can be neatly placed in the storage container. Utility Model Content
