[0030] The valve welding pipe according to the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 1 and Figure 2 As shown, the valve welding pipe provided in the embodiment of the utility model includes a pipe body 10, a connecting interface 20 and a sealing member 30. The connecting interface 20 is arranged at one end of the pipe body 10 and is constructed with an embedding groove 201 connected to the valve. A welding groove 202 is formed at the edge of the embedding groove 201, and the welding groove 202 is connected to the outer peripheral surface of the connecting interface 20; the sealing member 30 is arranged in the connecting interface 20 to seal the gap between the connecting interface 20 and the valve.

[0032] Among them, the seal 30 can be made of materials such as rubber, so that when the valve interface is connected to the connection interface 20, the seal 30 can be pressed against the valve interface, so that the seal 30 can better close the gap between the valve and the connection interface 20. Optionally, the height of the seal 30 is 1.5mm-2.8mm, and the valve interface can be provided with a corresponding sealing groove to make the overall sealing effect better.

[0033] The valve welding pipe provided in the embodiment of the utility model can be connected to the valve through the connecting interface 20 so that the sealing member 30 can seal the gap between the connecting interface 20 and the valve. At the same time, the valve interface can be embedded in the embedding groove 201, and then welded and fixed to the valve interface through the welding groove 202, so that the welding between the valve and the pipe body 10 is more stable, avoiding the bulge at the connection after welding, and improving the durability and aesthetics of the connection.

[0034] Reference Figure 2 and Figure 3 As shown, the connection interface 20 is further provided with a notch 203 , which is communicated with the welding groove 202 , so that the connection interface 20 and the valve can be welded and fixed via the notch 203 ; the notch 203 is in a semicircular shape that is relatively arranged.

[0035] In this embodiment, after the valve interface is docked with the connection interface 20, the welding part of the valve interface can be embedded in the welding groove 202. Since the notch 203 is connected to the welding groove 202, the notch 203 can be welded by a welding rod during welding, so that the welding rod can weld the welding part of the valve interface to the welding groove 202 through the notch 203. After welding, the cooperation between the welding groove 202 and the notch 203 can make the weld smoother, avoid the bulge at the connection after welding, and improve the durability and aesthetics of the connection.

[0036] Specifically, the depth of the welding groove 202 is 3.2mm-5.3mm; the cross-sectional structure of the welding groove 202 is V-shaped, suitable for fitting with the valve. The edge of the valve interface can be inserted into the welding groove 202, so that the valve interface corresponds to the notch 203, and then when welding with welding rods, the gap between the welding groove 202 and the notch 203 can be filled while the valve interface is welded and fixed to ensure the overall flatness.

[0037] Optionally, the diameter of the connection interface 20 is larger than the diameter of the pipe body 10. The valve interface can be plugged into the connection interface 20, so that the overall consistency of the valve and the pipe body 10 is better after welding.

[0038] Specifically, a welding edge 204 is formed on the end surface of the connection interface 20, and the welding edge 204 is configured to be chamfered; further, the chamfer angle of the welding edge 204 is 45 degrees or 60 degrees.

[0039] In this embodiment, when the connection interface 20 abuts against the valve interface, the welding edge 204 can form a V-shaped groove with the valve interface, so that the welding edge 204 can be welded with a welding rod, thereby ensuring that the welding between the pipe body 10 and the valve is more stable and reliable, and making the sealing between the connection interface 20 and the valve interface better.
