[0026] After the base 1 is placed on the corresponding valve position, the positioning groove 6 facilitates the stable placement of the base 1 to reduce slipping. The base 1 and the internal threaded pipe 3 are pressurized and welded to the valve by a welding machine. The welding block 5 is melted by pressurization. The impact force causes the melted molten liquid to be distributed inside the guide groove 4 through the guide groove 4. The uniformly arranged welding blocks 5 allow the molten liquid to fill the inside of the guide groove 4 to complete the welding with the valve. After the welded welding block 5 is melted, the molten liquid is guided by the guide groove 4 to flow into the reinforcement groove 7 and the extension groove 13. The solidified molten liquid is fixed to the extension groove 13 and the reinforcement groove 7 inside the reinforcement groove 7 and the extension groove 13, thereby increasing the adhesion area between the molten liquid and the base 1.

The grooves 9 are evenly opened on the outer side of the conical piece 8.

[0029] The conical piece 8 has a certain blocking effect on the melted liquid. The inclined slope increases the difficulty of the melt climbing up the slope and reduces the melt entering the interior of the through hole 2 through the gap to affect the subsequent bolt installation work.

[0030] In this embodiment, the protective member 11 includes a protective ring 10 and a reinforcement ring 15 . The protective ring 10 is located at the bottom of the internal threaded tube 3 , and the reinforcement ring 15 is located outside the protective ring 10 . The reinforcement ring 15 is fixedly connected to the outside of the internal threaded tube 3 .
