Structural difference between gate valve and ball valve
According to the shape, we can see that the opening and closing part of the stainless steel gate valve is a plate, and the stainless steel ball valve is a ball. The valve plate and valve core of the stainless steel gate valve are spirally rotated around their own axis. One of them is called stainless steel globe valve. Stainless steel gate valve and stainless steel globe valve are one that can adjust the flow, so stainless steel ball valve is not convenient to do this.
The characteristics of the stainless steel gate valve are the characteristics of rapid opening and closing, and the structure is also very simple, which is more convenient to use. The stainless steel globe valve has the characteristics of low cost and low tightness, and the pressure bearing capacity is not very good. The gate valve is similar, but it is affected by the limitation of volume and opening and closing resistance, and the resistance limitation also makes it difficult to achieve a large diameter. The structural principle of the stainless steel gate valve and the suitable large-diameter gate valve have the direction of the diameter of the installation pipe, but it can be rotated in the stainless steel gate valve and the cylindrical channel. It has good performance, high cost, and first-class sealing effect.
The secret recipe of the stainless steel ball valve is formed by the extrusion of the valve seat. It must wear faster than the stainless steel globe valve. Under the usual use of the stainless steel ball valve, the flexible structure is difficult to use the sealing form in the high temperature pressure pipeline.
