Conical head

Conical head is a head with a tapered surface on the housing. The feature is that the medium can change the speed uniformly when passing through, which is convenient for unloading viscous liquids and solid particles. In order to reduce the discontinuous stress, the large or small end of the conical shell can adopt a flanged structure with a circular arc transition or a locally thickened structure. Under the internal pressure of the main part of the tapered head cone, the film stress occurs at the large end. Due to the geometric discontinuity and the abrupt curvature radius, the joint between the cone and the cylinder will generate a large lateral thrust, cause a large edge stress, and easily bend, so it needs to be strengthened. For the large end, the axial bending stress is the main controlling factor and it is a secondary stress, so the stress intensity is controlled; for the small end, the average circumferential tensile stress and average stress are mainly due to the stress at the connection between the small end and the cylinder. Radial compressive stress is a local film stress, so the stress intensity can be controlled.
