Description

Technical Field

[0001] The utility model belongs to the technical field of flanges, in particular to a flange waterway with high sealing performance. Background Art

[0002] Flange is also called flange flange or flange. Flange is a part that connects pipes to each other. It is used to connect pipe ends. It is also used as flange on equipment inlet and outlet. It is used to connect two equipments. Flange is often provided with water channel. Flange water channel is used to set up flowing water flow inside the flange. The heat on the flange is taken away by the flowing water flow, so as to cool down some flanges installed in high temperature environment. However, the water channel on the flange still has the following disadvantages when welding:

[0003] 1. When installing the sealing plate for sealing the water channel on the existing flange, manual argon arc welding is generally used. The welding speed is slow when using argon arc welding, and the sealing plate is easy to deform, so that a gap is generated between the sealing plate and the flange body during sealing welding, which greatly reduces the sealing performance of the sealing plate to the flange water channel;

[0004] 2. The flange is usually equipped with two joints for connecting its internal water channels. Currently, the two joints are generally inserted into the flange first and then welded. When the joints and flanges are directly welded, the welding effect is poor and welding leaks are likely to occur.

[0005] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Utility Model Content

[0006] The utility model aims to provide a flange water channel with high sealing performance. The position of a water sealing plate placed on the upper end of an annular water tank is limited by two annular welding rods at the upper end of the outer wall of the flange body to avoid deformation of the water sealing plate during welding. At the same time, the arc-shaped inner chamfers 1 and 2 on each side form an arc-shaped groove. The two arc-shaped grooves can facilitate welding personnel to weld the flange body and the water sealing plate along the inner wall thereof, thereby solving the problems of slow welding speed and easy deformation of the water sealing plate during welding when installing the water sealing plate for closing the water channel on the existing flange.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:
