[0001] The utility model relates to the technical field of anti-corrosion tube sheets, in particular to an anti-corrosion tube sheet for installing heat exchange tubes. Background Art

[0002] The anti-corrosion tube sheet used for installing heat exchange tubes in heat exchangers is a tube sheet with anti-corrosion performance. It is used to connect the tube bundle and the shell of the heat exchanger and withstand the medium pressure. The main function of the anti-corrosion tube sheet is to prevent corrosion and leakage at the connection between the tube bundle and the shell, thereby ensuring the normal operation and service life of the heat exchanger. The anti-corrosion tube sheet is usually made of corrosion-resistant materials such as stainless steel and carbon steel, and its surface is specially treated, such as spraying anti-corrosion paint, electrochemical treatment, etc., to improve its corrosion resistance.

[0003] When the heat exchange tubes of the heat exchanger are connected to the anti-corrosion tube sheet, welding is usually used to fix the heat exchange tubes on the inner side of the anti-corrosion tube sheet so that the heat exchange tubes will not leak the medium at the position where they pass through the anti-corrosion tube sheet. This makes the heat exchange tubes firmly installed and enhances the connection strength and sealing performance between the tube bundle and the shell.

[0004] However, the anti-corrosion tube sheet for installing the heat exchange tube is installed by welding, which makes it difficult to remove the heat exchange tube when the heat exchange tube needs to be repaired, making the heat exchange tube maintenance inconvenient. In view of this, the present application proposes an anti-corrosion tube sheet for installing the heat exchange tube. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an anti-corrosion tube sheet for installing heat exchange tubes, which has the advantages of being able to quickly separate the heat exchange tubes from the anti-corrosion tube sheet during maintenance. It solves the problem that installation by welding makes it difficult to dismantle the heat exchange tubes when maintenance of the heat exchange tubes is needed, thus making the maintenance of the heat exchange tubes inconvenient.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-corrosion tube sheet for installing a heat exchange tube, comprising an anti-corrosion tube sheet, a plurality of installation sleeves are penetrated on one side of the anti-corrosion tube sheet, a welding-free leak-proof component is provided at one end of the installation sleeve located on the inner side of the anti-corrosion tube sheet, and a heat exchange tube is penetrated inside the installation sleeve;

[0007] The weld-free leak-proof component comprises a locking nut sleeved on the surface of a mounting sleeve, a locking split tube is fixedly mounted on one end of the mounting sleeve, and a baffle is fixedly mounted on one end of the locking split tube.

[0008] Furthermore, the surface of the installation sleeve located on the inner side of the anti-corrosion tube plate is provided with an installation external thread, and the locking nut is threadably installed on the surface of the installation sleeve through the installation external thread.

[0009] Furthermore, a locking external thread is provided on the surface of the locking split pipe, and the locking external thread is matched with a locking nut.

[0010] Furthermore, an inner side wall of the locking split tube is provided with an embedded groove, a sealing ring is embedded in the inner side of the embedded groove, and the inner wall of the sealing ring is in contact with the surface of the heat exchange tube.

[0011] Furthermore, the anti-corrosion tube sheet is provided with welding grooves on both sides of the installation sleeve passing through, and the installation sleeve is welded to the anti-corrosion tube sheet.

[0012] Furthermore, a mounting through hole is opened on one side of the anti-corrosion tube sheet, a connecting flange is bolted on one side of the anti-corrosion tube sheet, a container is fixedly installed inside the connecting flange, and the heat exchange tube is located inside the container.

[0013] Furthermore, a butt joint pipe adapted to the container is fixedly mounted on one side of the anti-corrosion tube plate, and a sealing ring is embedded on the surface of the butt joint pipe.

[0014] Compared with the prior art, the utility model provides an anti-corrosion tube sheet for installing heat exchange tubes, which has the following beneficial effects:

[0015] The anti-corrosion tube plate for installing the heat exchange tube is formed by welding an installation sleeve on one side of the anti-corrosion tube plate, and arranging a weld-free leak-proof component on one side of the installation sleeve.
