Eccentric cone

Abstract

The invention discloses an eccentric cone comprising an upper straight edge, a cone part and a lower straight edge. The two ends of the cone part are respectively connected with the lower end face of the upper straight edge and the upper end face of the lower straight edge, wherein the upper end face of the upper straight edge and the lower end face of the lower straight edge are parallel, and are commonly vertical to the same conical surface generatrix of the cone part. Due to the structure of the eccentric cone, equipment connected with the cone and the eccentric cone can be kept at the same horizontal plane; when the eccentric cone is connected, the eccentric cone does not need to be suspended or an extra supporting part is not needed; and the discharging difficulty of the eccentric cone is greatly reduced and load and stress applied on the cone are reduced, so that the eccentric cone is very suitable for a pressure container, a pressure pipeline and a connection transition body, which are arranged in parallel.

Description

technical field [0001] The invention belongs to the field of pressure equipment, in particular to an eccentric cone of a pressure vessel. Background technique [0002] The head is an indispensable and important part of pressure vessel equipment in many industries from petrochemical, atomic energy, to food, pharmaceutical and so on. The head is an important part of the equipment. It is connected with the cylinder to form the shell of the equipment. The head and the cylinder can be directly welded to form a non-detachable connection. The advantage of this connection method is that the connection cost is low, The sealing performance is good, and the leakage accident in the production process is not easy to occur. [0003] As a part of the container, the head can be divided into spherical, oval, dish, spherical crown, conical shell and flat cover according to the geometric shape and different fields of application. Among them, spherical, oval, dish, spherical The crown head is...

AI Technical Summary

Problems solved by technology

However, the existing conical heads can only be installed vertically, especially in the process of being used as a diameter-changing section. The existing conical heads cannot keep the equipment connected front and back on the same water surface. Difficult, and the suspension of the cone part also increases the load and stress of the reducing section

Especially in heat exchanger equipment, the existing conical head is difficult to maintain the same level with the lower end of the heat exchanger body, which seriously affects the heat exchange effect
