Anti-falling automatic tube penetration guide cone

Abstract

The invention discloses an anti-falling automatic tube penetration guide cone. The anti-falling automatic tube penetration guide cone comprises a tightening bolt and a tightening nut, wherein the tightening bolt is in threaded connection with the tightening nut. A guide cone body is assembled on the tightening bolt. The cone end face of the guide cone body is drawn close to the flat end face of the tightening nut. A rubber tube is further assembled on the tightening bolt. One end of the rubber tube is assembled to be flush with the end face of the guide cone body, and the other end of the rubber tube abuts against the step round face of a handle of the tightening bolt. According to the anti-falling automatic tube penetration guide cone, the special combination of the tightening bolt, the tightening nut, the guide cone body, an anti-rotation screw and the rubber tube is adopted, and the characteristic that rubber is extremely high in plasticity is utilized, so that the several components are combined into the anti-falling automatic tube penetration guide cone which has certain rigidity, can achieve guiding, is quite good in plasticity and can resist to fall and be taken out easily;and the problems that a heat exchange tube of a fixed tube-plate type heat exchanger with the shell pass being in a U shape cannot be guided and assembled through manual work, heat exchange tubes of general fixed type heat exchangers are difficult to assemble and low in assembling efficiency, and certain heat exchange tubes internally leak and cannot be replaced when the pressure test is conductedon the heat exchangers are solved.

Description

technical field [0001] The invention relates to an anti-falling-off automatic pipe-piercing guide cone, which belongs to the technical field of metal shell-and-tube heat exchanger construction. Background technique [0002] A heat exchanger, also known as a heat exchanger or a heat exchange device, is a device that transfers part of the heat of a hot fluid to a cold fluid. Heat exchangers are common equipment in chemical industry, petroleum, power, food and many other industrial sectors, and play an important role in production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are more widely used. [0003] There are many types of heat exchangers, but according to the principle and method of heat exchange between cold and hot fluids, they can basically be divided into three categories: partition wall type, hybrid type and heat storage type. Among the three types of heat exchangers, partition wall heat ...
