Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to an anti-skid flange for marine engineering. Background Art

[0002] Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as a reducer flange. Flange connection or flange joint refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a combined sealing structure.

[0003] Authorization announcement number CN216382979U A kind of anti-skid and wear-resistant special alloy flange for marine engineering. The connecting block of the first flange is installed into the connecting groove of the second flange, so that the first flange and the second flange can be aligned with each other, which is convenient for fixing the two flanges for connection. Then the fixing block is installed on the outside of the connecting block and the connecting groove, so that the right-angled trapezoids at both ends abut against the oblique grooves of the first flange and the second flange, and then the bolt is installed in the embedded groove so that the tail end and the threaded hole are threadedly connected. Since the direction of the threaded hole is on the outside, the utility model has a large operating space, which is convenient for connection, and the oblique grooves at both ends of the fixing block and the two flanges can be used. Self-locking is achieved, and the embedded structure of the bolts prevents the bolts from loosening due to collision during the movement of the whole; the sealing gasket is sleeved on the outside of the pipe insert, which is convenient for the installation of the sealing gasket and prevents deviation, and the pipe insert is inserted into the connecting pipe of the second flange, which can further achieve sealing and prevent leakage; however, the bottom teeth of the flange nut used for marine engineering in this solution are still relatively smooth, and the anti-skid effect is still low. Since the bottom teeth are relatively smooth, when the finger membrane passes over the bottom teeth, it feels relatively smooth. After long-term use, the anti-skid effect is greatly reduced. Therefore, an anti-skid flange for marine engineering is needed to improve the above problems. Utility Model Content

A nut 210 is arranged on the side of the rubber ring 209, and a low-alloy structural steel rod 211 is arranged on the side of the nut 210. The structural design of using the anti-slip toothed nut 206 to cooperate with the abutment block 203 and the sealing ring 204 is relatively reasonable. The anti-slip tooth pattern at the bottom is a wedge-shaped structure with one side thick and the other side thin, and the downward inclination direction of the shape surface is the same as the tightening direction of the nut body. During the tightening process, the thinner side of the anti-slip tooth pattern first passes through the surface of the workpiece to facilitate screwing in. After tightening, the abutment block 203 and the sealing ring 204 have a resisting effect on the anti-slip toothed nut 206, which plays a restraining role and enhances the anti-slip performance.

[0027] Among them, the threaded rod 201 passes through the clamping ring 202, the abutment block 203, the sealing ring 204, the internal threaded sleeve 205 and the anti-slip toothed nut 206, the threaded rod 201 passes through the washer 207, the threaded rubber pad 208, the rubber ring 209, the nut 210 and the low-alloy structural steel rod 211, the internal threaded sleeve 205, the abutment block 203, the threaded rubber pad 208 and the nut 210 are threadedly connected with the threaded rod 201, and the rubber ring 209 and the threaded rubber pad 208 are used. The rubber ring 209 fills the gap between the smooth area of ​​the nut 210, which is beneficial to prevent sliding between the nut 210 and the threaded rod 201, and the outer surface of the clockwise nut 210 and the outer surface of the counterclockwise nut 210 are wrapped with the threaded rubber pad 208. The threaded rubber pad 208 strengthens the friction of the threaded connection, which is beneficial to prevent sliding between the bolt and the connected object.

[0028] In this embodiment, Figure 1 and Figure 2 As shown, the flange body 1 includes a connecting disc body 101, and a first flange body 102 and a second flange body 103 are arranged on the side of the connecting disc body 101. A positioning block 107 and an embedded ring seat 108 are fixedly connected inside the first flange body 102. There are several positioning blocks 107, and there are two embedded ring seats 108. A second through hole 106 is opened inside the first flange body 102, and a first through hole 105 is opened inside the second flange body 103. There are several first through holes 105 and second through holes 106. A middle hole 104 is opened inside the connecting disc body 101, and there are several middle holes 104. The embedded ring seat 108 can increase the internal stability of the flange and increase the service life.

[0029] The working process of the utility model is as follows: when using the anti-skid flange for marine engineering designed by the present invention, the first flange body 102 and the second flange body 103 are gathered and pressed against the connecting body 101, so that the middle hole 104, the first insertion hole 105 and the second insertion hole 106 are on the same vertical line, and the threaded rod 201 is inserted into the middle hole 104, the first insertion hole 105 and the second insertion hole 106 respectively, and the clamping ring 202 is inserted into one side of the threaded rod 201 and then screwed into the abutment block 20 3.

On the other side of the threaded rod 201, insert the washer 207 and the rubber ring 209 and screw in the threaded rubber pad 208 and the nut 210. This can not only reduce the gap between the connecting disc body 101, the first flange body 102 and the second flange body 103, increase the airtightness therebetween, but also play a role in preventing the connection from slipping.
