Gate valve and ball valve structure difference
Stainless steel ball valve and stainless steel gate valve what are the differences? According to the shape, we can see that the stainless steel gate valve is a piece of open and close, and stainless steel ball valve is a ball. The valve plate and spool of the stainless steel gate valve are twisted around their axis. One of them is called stainless steel cut-off valve is also a kind of stainless steel gate valve and stainless steel cut-off valve is one of the flow can be adjusted, then stainless steel ball valve is not easy to do this.
The characteristics of stainless steel valve has the characteristics of rapid opening and closing, and the structure is very simple, more convenient to use, stainless steel valve has the characteristics of low cost and low point of tightness, the bearing capacity is not very good, and the characteristics of stainless steel valve stainless steel ball valve is similar, but by the opening and closing volume and resistance limit effect the resistance restrictions have made it difficult to achieve large caliber. The structure and principle of stainless steel gate valve suitable for large-diameter valve is installed in the pipe diameter direction, but stainless steel valve and a cylindrical channel can be rotated, its performance is good, high cost, and the sealing effect is excellent.
Stainless steel ball valve seat for extrusion secret is formed, it is stainless steel valve must wear faster, usually adopts stainless steel ball valve, flexible structure is also difficult to use high temperature sealing form in pressure pipeline. Stainless steel valve rubber sealing far place in metal hardware for the hemisphere valve and gate valve, the heat generated in the long term can get wear after use, it can be adjusted by the continued use of the stem and in the process of opening and closing of the rotation, leaks and signs at the same time, the use of a bolt, can achieve a goal.
