Technical Field

[0001] The utility model relates to the technical field of seamless steel pipes for boilers, in particular to a seamless steel pipe for boilers. Background Art

[0002] Seamless steel pipes for boilers are specially designed pipe materials with a continuous, hollow cylindrical structure without welded joints. This type of steel pipe is specially used in boiler systems, especially thermal equipment working under high or ultra-high pressure conditions, such as power station boilers, industrial boilers, steam generators, etc. With their seamless structure, selected materials and strict manufacturing standards, they play a vital role in ensuring the safe, reliable and efficient operation of boilers.

When in use, one end of the threaded pipe of the butt-jointed steel pipe is inserted into the connecting pipe, and the elastic force of the spring sheet is used to clamp the fixing pad into the inside of the butt-jointed groove to prevent the connection end from loosening. However, in the process of using the seamless steel pipe, due to the continuous flushing of the fluid and the vibration generated by the operation of the equipment, the bolts and nuts at the connection parts often encounter the problem of loosening, which not only weakens the original sealing effect, but also causes the leakage of the liquid medium, posing a threat to the safety of equipment operation and work efficiency.

[0004] Therefore, we provide a seamless steel pipe for boilers to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a seamless steel pipe for boilers to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a seamless steel pipe for a boiler, comprising a steel pipe body and an anti-loosening mechanism, a connecting plate is installed on the outer side of the steel pipe body, and an anti-loosening mechanism is provided on one side of the connecting plate;

[0007] The anti-loosening mechanism includes a fixing component, an anti-slipping component, a connecting component, a stabilizing component, a vibration-damping component and a control component.

[0009] Preferably, the anti-slip assembly includes a nut, an anti-slip gasket and a sealing ring, the surface of the bolt is threadedly connected with a nut, an anti-slip gasket is installed on one side of the nut, and a sealing ring is installed on the inner side of the steel pipe body.

[0010] Preferably, the connecting assembly comprises an insert block and a base, the insert block is installed at the bottom end of the sealing ring, and the base is installed on the inner wall of the connecting disk.

[0011] Preferably, the stabilizing assembly includes a spring and a stabilizing block, the spring is installed on the surface of the base, and the stabilizing block is installed on the other side of the spring.

[0012] Preferably, the vibration reduction assembly comprises a connecting block and an elastic buckle, the connecting block is installed on the surface of the anti-drop gasket, and the elastic buckle is installed on the outer side of the connecting block.

[0013] Preferably, the control assembly includes a fixing piece and a control button, the fixing piece is arranged on the outer side of the elastic buckle, and the control button is installed on the top of the fixing piece.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Through the setting of the anti-loosening mechanism, when installing the bolt, first install the toothed gasket between the bolt and the connecting plate. The toothed structure undergoes plastic deformation when subjected to the bolt tightening force, thereby enhancing the tightening force and sealing performance of the connection. In addition, an anti-slip gasket is installed at the nut. Its function is to further enhance the stability of the threaded connection through a unique design, and effectively prevent the nut from loosening due to factors such as vibration and impact. Then, the sealing ring is embedded in the connecting plate. The plug-in block under the connecting plate squeezes the corresponding stabilizing block inward under the action of the installation force. The stabilizing block moves outward after being compressed, causing the spring connected to it to contract. When the groove on the plug-in block is fully matched with the protrusion on the stabilizing block, the elastic force accumulated in the spring is released, driving the stabilizing block to fit closely with the plug-in block, thereby forming a stable locking structure, thereby making the sealing plate and the connecting plate tightly connected, thereby increasing the overall sealing.

[0017] 2. Through the setting of the vibration reduction component, the elastic clip is inserted into the fixing part, and the plug-in is inserted into the socket at the same time to complete the installation of the anti-dropping gasket. When the equipment encounters vibration during operation, the pre-installed anti-dropping gasket can effectively absorb and resolve most of the vibration force it bears by virtue of its linkage with the elastic clip. In this way, even in the face of continuous or severe vibration environment, the impact on the nut will be greatly reduced, and its tightening state will be effectively guaranteed, which greatly enhances the stability of the connection and reduces the risk of nut loosening due to vibration.
