[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a stainless steel pipe for a high-pressure boiler that is securely installed, and has the following advantages:

[0016] Enhanced Installation Stability: A robust support mechanism is installed in the middle of the stainless steel pipe body. This mechanism includes components such as a fixing ring, a fixing seat, a support rod, and a support plate. The fixing ring is fixedly connected to the stainless steel pipe body, and the support plate is connected to the high-pressure boiler through a connecting mechanism. The support rod is rotatably connected through an installation mechanism, forming a stable support structure. This method changes the previous method of fixing only with flanges and screws, effectively solving the problem of easy shaking of steel pipes. It significantly improves the stability of the stainless steel pipe after installation, avoids gaps at the installation joints caused by shaking, and thus eliminates the safety hazard of leakage.

[0017] Improved efficiency and effectiveness: Stable installation reduces equipment failures and maintenance frequency caused by steel pipe shaking and leakage, enabling stainless steel pipes to function continuously and stably in high-pressure boilers. This enhances the efficiency and effectiveness of stainless steel pipes, improves the overall operational stability and reliability of the equipment, and thus enhances the practicality of the product.

[0018] Enhanced connection strength: The connection mechanism uses connecting bolts to fix the support plate to the high-pressure boiler. The connection method is simple and reliable, which can ensure a firm connection between the support plate and the high-pressure boiler, providing a stable foundation for the stable support mechanism, thereby ensuring the stability of the entire stainless steel pipe installation structure.

[0019] Vibration and noise reduction: The vibration-damping rubber pads installed at the bottom of the support plate effectively absorb the vibration and noise generated by the stainless steel pipes during operation. This not only reduces the impact on the equipment and the surrounding environment but also lowers the risk of loosening connections due to vibration, further improving the stability and service life of the stainless steel pipes after installation. Furthermore, the 5mm thick vibration-damping rubber pads ensure effective vibration reduction without significantly affecting the connection between the support plate and the high-pressure boiler.

[0020] Uniform stress distribution: The stable support mechanism is evenly distributed in a ring around the fixed ring, so that the stainless steel pipe can receive uniform support force in all directions, avoiding uneven local stress and further enhancing the stability and reliability of the stainless steel pipe after installation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4A stainless steel pipe for a high-pressure boiler with stable installation includes a stainless steel pipe body 1, a flange 2 and screws 3. The flange 2 is provided at the bottom end of the stainless steel pipe body 1. The flange 2 is fixedly installed to the corresponding high-pressure boiler by multiple sets of screws 3. A stable support mechanism is provided in the middle area of ​​the stainless steel pipe body 1.

[0028] The stabilizing support mechanism also includes a fixing ring 4, a fixing seat 5, a support rod 6, and a support plate 7. The middle part of the stainless steel pipe body 1 is fixedly connected to the corresponding fixing ring 4. A fixing seat 5 is fixedly installed on the fixing ring 4. A fixing seat 5 is fixedly installed on the support plate 7. The fixing seats 5 are rotatably connected to the corresponding support rod 6 through an installation mechanism. The bottom end of the support plate 7 is connected to the corresponding high-pressure boiler through a connecting mechanism.

[0029] When this device is in use

[0030] Installation preparation: First, align the flange 2 at the bottom of the stainless steel pipe body 1 with the corresponding flange 2 on the high-pressure boiler, and then use multiple sets of screws 3 to fix the two together, thus completing the initial installation of the stainless steel pipe body 1 and the high-pressure boiler.

[0031] Installation of the stable support mechanism: Install the fixing seat 5 on the fixing ring 4; similarly install the fixing seat 5 on the support plate 7. Insert one end of the support rod 6 into the rotating groove 10 on one side of the fixing seat 5, and then insert the insertion rod 8 through the corresponding support rod 6 and fixing seat 5, so that the support rod 6 is hinged to the fixing seat 5 through the insertion rod 8. The limiting plates 9 on both sides of the insertion rod 8 can prevent the insertion rod 8 from falling off, thus completing the assembly of the installation mechanism. Afterwards, place a 5 mm thick shock-absorbing rubber pad 12 at the bottom of the support plate 7, and then fix the support plate 7 to the high-pressure boiler with multiple sets of connecting bolts 11. This completes the installation of the stable support mechanism.

[0032] Usage: During the operation of the high-pressure boiler, the vibration generated by the stainless steel pipe body 1 when transmitting the medium is first transmitted to the fixing ring 4 fixed on it, and then to the support plate 7 through the support rod 6. Since the support rod 6 is hinged to the fixing seat 5, it can disperse the vibration direction to a certain extent. At the same time, the shock-absorbing rubber pad 12 at the bottom of the support plate 7 can absorb most of the vibration energy, reducing the vibration transmitted to the high-pressure boiler and preventing the stainless steel pipe from shaking or loosening due to vibration. The stable support mechanism is evenly distributed in a ring around the fixing ring 4, which can make the stainless steel pipe receive uniform support force in all directions, ensuring that the stainless steel pipe remains in a stable installation state during the operation of the high-pressure boiler, effectively preventing safety hazards such as leakage, and ensuring the stable operation of the equipment.
