Floating head type heat exchanger pipe bundle shell side pressure test tool

Abstract

The invention discloses a floating head type heat exchanger pipe bundle shell side pressure test tool. The floating head type heat exchanger pipe bundle shell side pressure test tool comprises a packing culvert, a packing press ring and an O-shaped rubber sealing ring; and one side of the packing culvert is connected with a flange of the outer head cover side of a floating head type heat exchanger, a movable pipe plate is arranged in a packing culvert cylinder joint of the packing culvert, the packing press ring comprises a packing press ring cylinder joint, the end, located in the packing culvert cylinder joint, of the packing press ring cylinder joint abuts against a movable pipe plate sealing surface, and the other end of the packing press ring cylinder joint is connected with the packing culvert in a flange mode. According to the floating head type heat exchanger pipe bundle shell side pressure test tool, the type of the packing press ring pressing the sealing surface of the movable pipe plate is adopted by the sealing of a heat exchanger shell side and the movable pipe plate, by controlling the lengths of the packing culvert cylinder joint and the packing press ring cylinder joint, the requirements of different lengths of the movable pipe plate protruding a heat exchanger cylinder body can be met, and the universality of the pressure test tool is strengthened. A first sealing ring and a second sealing ring enable sealing elements to be interchangeable, reuse can be achieved, the use cost is low, and installation and use are convenient and easy.

Description

technical field [0001] The invention is a tooling used by a chemical enterprise for shell-side pressure testing to check whether the tube bundle of a heat exchanger leaks during the manufacture and maintenance of a floating-head heat exchanger tube bundle, and in particular relates to a shell-side pressure test tooling for a floating-head heat exchanger tube bundle. Background technique [0002] Traditional pressure test tooling has poor versatility. For different heat exchangers with the same nominal diameter and the same design pressure, the length of the heat exchanger tube bundle protruding from the heat exchanger shell is different. Traditional pressure test tooling cannot be interchanged; traditional pressure test tooling accessories It is inconvenient to install and use, and requires high operating skills for workers; the seals of traditional pressure test tools are not universal and cannot be reused, and the cost of use is high.
