[0007] As a preferred technical solution of the utility model, the clamping assembly includes a push rod, the end of which is fixedly connected to a push plate, the push plate moves laterally inside the clamping seat, the push plate is made of rubber, and a plurality of protrusions are preset on the surface of the push plate.

[0008] As a preferred technical solution of the utility model, both sides of the outside of the holder are threadedly connected with fastening bolts, the ends of the fastening bolts pass through the holder, and the ends of the fastening bolts are connected to the tail end of the push rod.

[0009] As a preferred technical solution of the utility model, a connecting rod is fixedly connected to the outer side wall of the connecting plate, the end of the connecting rod is bent downward, and the bent end of the connecting rod is connected to the top of the socket.

[0010] As a preferred technical solution of the present invention, reinforcement bolts are connected around the middle of the flange joint body.

[0011] Compared with the prior art, the beneficial effect of the utility model lies in that: the clamping seats that can contact the surface of the stainless steel pipe are evenly installed at both ends of the flange joint body, and at the same time, adjustable push plates are arranged on both sides of the inner side of the clamping seat, so that after the flange joint body and its stainless steel pipe are docked, the clamping seat can be used to connect with the stainless steel pipe again, thereby improving the stability of the flange joint body and the stainless steel pipe and improving the overall firmness.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0017] Reference Figure 1-2 A stainless steel pipe flange joint comprises a flange joint body 1, both ends of the flange joint body 1 are connected to sealing rings 4, connecting plates 2 are installed on both sides of the top of the flange joint body 1, and a clamping seat 5 is arranged on the outer side of the connecting plate 2. The two clamping seats 5 are flush with the sealing ring 4, and clamping components are arranged on the two inner sides of the clamping seat 5, which can contact the outer wall of the stainless steel pipe.

[0018] The clamping assembly includes a push rod, the end of which is fixedly connected to a push plate 8. The push plate 8 moves laterally inside the clamping seat 5. The push plate 8 is made of rubber, and a plurality of protrusions are preset on the surface of the push plate 8.

[0019] Both sides of the outside of the clamping seat 5 are threadedly connected to the fastening bolts 7, and the ends of the fastening bolts 7 pass through the clamping seat 5, and the ends of the fastening bolts 7 are connected to the tail end of the push rod.

[0020] A connecting rod 6 is fixedly connected to the outer side wall of the connecting plate 2 , and the end of the connecting rod 6 is bent downward, and the bent end of the connecting rod 6 is connected to the top of the holder 5 .

[0021] The middle of the flange joint body 1 is connected with reinforcement bolts 3 all around. In order to ensure the stability of the flange joint body 1 itself, multiple reinforcement bolts 3 are provided to improve the overall support strength and improve the sealing performance of the connection with the stainless steel pipe.

[0022] During operation, firstly, the sealing ring 4 in the middle of the flange joint body 1 is used to connect with the stainless steel pipe, and the reinforcing bolt 3 is a bolt to ensure the firmness of the two groups of stainless steel pipes after being connected through the flange joint body 1. Then, according to the tail of the stainless steel pipe, its holder 5 is clamped on the surface of the stainless steel pipe, and the fastening bolt 7 is adjusted according to the diameter of the stainless steel pipe itself, that is, by rotating the fastening bolt 7, the push plate 8 is allowed to achieve lateral movement inside the holder 5. When the fastening bolt 7 cannot be rotated again after contacting the surface of the stainless steel pipe, it means that the fastening is completed, thereby improving the stability of the flange joint body 1 and the stainless steel pipe and improving the overall firmness.
