Abstract

A sealing seat for a tubular heat exchanger includes a seat body including a first connecting end for connecting to a connector of the exchanger and a second connecting end for connecting to an outertube of the exchanger, a main chamber, a central passage communicating with the main chamber, and an auxiliary passage communicating with the main chamber. The seat body includes a first connecting end for connecting to the connector of the exchanger and a second connecting end for connecting to an outer tube of the exchanger. The outer surface of the first connecting end is provided with a three-stage connecting surface which is distributed in a step shape, and each stage connecting surface is provided with a connecting groove, and the surface of the connecting groove is provided with a sealing gasket. A plurality of sets of threaded holes are arranged on the outer circumferential surface of the second connecting end, each set of threaded holes is uniformly distributed along the circumferential direction, and each set of threaded holes comprises at least two threaded holes arranged at intervals. By setting the three-stage connecting surface, the corresponding connecting surface can beselected to connect with the exchanger joint according to the size of the exchanger joint, thus improving the applicable range of the sealing seat.

Description

technical field [0001] The invention relates to a sealing seat of a tube heat exchanger. Background technique [0002] At present, in tubular heat exchangers, there is generally a temperature difference between the medium of the inner tube and the outer tube, and heat is exchanged between the outer wall of the inner tube and the medium of the outer tube to achieve the purpose of heating or cooling a medium. [0003] Tubular heat exchangers generally include a sealing seat, an exchanger joint, an outer tube of the exchanger and an inner tube of the exchanger arranged inside the outer tube of the exchanger. A sealing seat adapted to it has a small application range. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a sealing seat for a tubular heat exchanger with a wide application range. [0005] In order to solve the problems of the technologies described above, the technical solution adopted in the present inven...
