What are the advantages and disadvantages of space frame ball valve nodes
The space frame ball valve can ensure that the space frame can achieve a large span to a large extent, and it is also conducive to the space frame to make various unique shapes. However, each welding ball has different advantages and disadvantages according to the needs of different space frame. Let's take a look at some common advantages and disadvantages of space frame accessories processing. The common node bolts and ball nodes of the space frame are realized by connecting the rod and the ball through high-strength bolts. The end of the rod is connected to the sealing plate with equal strength (the diameter of the steel pipe is less than φ 75.5) or the taper head (the diameter of the steel pipe is less than or equal to φ 75.5), the bolt ball is used as the split surface, and there is a hexagonal sleeve between the split surface and the sealing plate or the taper head. A small hole is opened on the sleeve, and a fastening pin is placed, the pin is embedded in the groove o
