Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a cast steel pipe made of heat-resistant stainless steel. Background Art

[0002] Stainless steel heat-resistant steel is widely used in the manufacture of equipment and components for various harsh environments such as high temperature and corrosion. Cast steel pipes are mainly used to manufacture high-strength, high-toughness and wear-resistant mechanical parts, such as parts for machine tools, automobiles, ships and other fields. The high strength, high wear resistance and high corrosion resistance of cast steel pipes make them an indispensable and important part in the energy industry. Heat-resistant stainless steel cast steel pipe connecting valves are popular among people due to their long service life. However, the current cast steel pipe connecting valves are integrally formed with the base, which makes it inconvenient to disassemble and assemble the cast steel pipe connecting valve after installation. The overall disassembly and assembly are required, which is inconvenient to use. In addition, the diameter of the connecting port of the cast steel pipe connecting valve is fixed, resulting in poor applicability and inability to connect water pipes of different diameters. In view of this, in-depth research was conducted on the above problems, which led to the creation of this case. Utility Model Content

[0012] The utility model provides a connecting plate, a screw and a mounting block. The connecting plate is installed on the base, and the mounting block is positioned and clamped into the mounting groove. After the locking plate is rotated, the screw rotates in the threaded hole at the same time, and the threads cooperate so that the screw is tightened in the threaded hole. At the same time, the locking plate and the mounting block are in a vertical state, thereby realizing the installation between the connecting plate below the cast steel pipe body and the base. When disassembling, the locking plate is rotated in the opposite direction so that the locking plate and the mounting block are in a horizontal state.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1-Figure 5 A heat-resistant stainless steel cast steel pipe comprises a base 1, a connecting plate 12 and a mounting groove 15. The top of the base 1 is mounted with the connecting plate 12, and the top of the connecting plate 12 is mounted with a cast steel pipe body 2. Both sides of the cast steel pipe body 2 are connected with connecting pipes 3, and the outer wall of one end of the connecting pipe 3 is mounted with a flange 4, and the inner side of one end of the connecting pipe 3 is mounted with an increase pipe 5;

[0022] The outer wall of one end of the connecting pipe 3 is evenly provided with a positioning chute 7, and the outer wall of the additional pipe 5 is evenly connected to the positioning chute 7 through a positioning slider 6, and the inner side of the positioning chute 7 is provided with an inner groove 8;

[0023] There are four positioning chutes 7 and four positioning slide blocks 6, and the positioning chutes 7 and the positioning slide blocks 6 are symmetrical with respect to the center point of the increasing tube 5.

[0024] The outer wall of one end of the increasing pipe 5 is provided with a recess 9, and the inner side of the recess 9 is installed with a sealing ring 10;

[0025] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, when this structure is used, a water pipe can be connected through one end of the connecting pipe 3, and the positioning slider 6 of the additional pipe 5 is positioned in the positioning chute 7. When the positioning slider 6 moves to the innermost side of the positioning chute 7, the additional pipe 5 is rotated to make the positioning slider 6 fit into the inner groove 8, so that the additional pipe 5 is installed and fixed on the inner side of the connecting pipe 3. By installing the sealing ring 10 in the recess 9, the sealing between the additional pipe 5 and the connecting pipe 3 is achieved. By installing the additional pipe 5, the diameter of the connecting port of the connecting pipe 3 can be changed, which is suitable for connecting water pipes of different diameters and has strong applicability.

[0026] Example 2: The top of the connecting plate 12 is evenly provided with mounting grooves 15, and the top of the base 1 inside the mounting grooves 15 is evenly provided with mounting blocks 13;

[0027] The top of each mounting block 13 is provided with a threaded hole 16, and a screw rod 11 is threadedly installed inside the threaded hole 16, and the top of each screw rod 11 is connected to a locking plate 14;

[0028] The mounting groove 15 is rectangular in top view, and the length of the mounting groove 15 is slightly longer than the sum of the lengths of the mounting block 13 and the locking plate 14;

[0029] Specifically, such as Figure 1 、 Figure 4 and Figure 5 As shown, when using this structure, by installing the connecting plate 12 on the base 1, the mounting block 13 is positioned and stuck in the mounting groove 15. After rotating the locking plate 14, the screw 11 rotates in the threaded hole 16 at the same time, and the threads are matched, so that the screw 11 is tightened in the threaded hole 16. At the same time, the locking plate 14 and the mounting block 13 are in a vertical state, thereby realizing the installation between the connecting plate 12 below the cast steel pipe body 2 and the base 1. When disassembling, the locking plate 14 is rotated in the opposite direction so that the locking plate 14 and the mounting block 13 are in a horizontal state, and the connecting plate 12 is removed upward. At the same time, the mounting block 13 is away from the mounting groove 15, which can realize the separation between the cast steel pipe body 2 and the base 1, and facilitate the disassembly and assembly of the cast steel pipe body 2.

[0030] Working principle: When using this device, first, the cast steel pipe body 2 is a heat-resistant stainless steel cast steel pipe. The steel pipe product is a connecting valve. The connecting pipes 3 at both ends of the cast steel pipe body 2 respectively work for water inlet and water outlet. The cast steel pipe body 2 can be installed and fixed on the equipment in use through the base 1;

[0031] Implementation steps for the first innovation point:

[0032] Step 1: Connect the water pipe through one end of the connecting pipe 3, and position the positioning slider 6 of the additional pipe 5 in the positioning chute 7. When the positioning slider 6 moves to the innermost side of the positioning chute 7, rotate the additional pipe 5 so that the positioning slider 6 is stuck in the inner groove 8, so that the additional pipe 5 is installed and fixed on the inner side of the connecting pipe 3;

[0033] Step 2: Install the sealing ring 10 in the recess 9 to achieve sealing between the additional pipe 5 and the connecting pipe 3. By installing the additional pipe 5, the diameter of the connecting port of the connecting pipe 3 can be changed, which is suitable for connecting water pipes of different diameters.

[0034] Implementation steps for the second innovation point:

[0035] Step 1: Install the connecting plate 12 on the base 1, and at the same time, position the mounting block 13 into the mounting groove 15. After rotating the locking plate 14, the screw 11 rotates in the threaded hole 16 at the same time, and the threads are matched so that the screw 11 is tightened in the threaded hole 16. At the same time, the locking plate 14 and the mounting block 13 are in a vertical state. There may be some position deviation, but the same effect can be achieved, thereby realizing the installation between the connecting plate 12 below the cast steel pipe body 2 and the base 1;

[0036] Step 2: When disassembling, rotate the locking plate 14 in the opposite direction so that the locking plate 14 and the mounting block 13 are in a horizontal state, remove the connecting plate 12 upward, and at the same time, the mounting block 13 is away from the mounting groove 15, so that the cast steel pipe body 2 and the base 1 can be separated.
