Conical head is a head with conical surface of shell. The characteristic is that it can make the medium pass through with uniform change of speed, and it is easy to unload the viscous liquid and solid particle-containing materials, but the mechanical property is poor, and the discontinuous stress generated by the sudden change of shape at the connection with cylinder or receiver is large.....
