In one embodiment, the thin plate is divided into a first thin plate and a second thin plate according to the distance from the bolt end, wherein the first thin plate is close to the bolt end, and a gasket is arranged between the first thin plate and the bolt end.
In one embodiment, a layer of solder strips is attached to the end of the shim opposite the bridge tube.
In one embodiment, the second thin plate is far away from the end of the bolt, and a nut is screwed beside the second thin plate.
In one embodiment, the center of the thin plate is provided with a round hole and is made of stainless steel.
In one embodiment, the round hole is in clearance fit with the bolt; the thin plate can move on the bolt.
In one embodiment, the bridge pipe is provided with a valve body and is communicated with the gas collecting pipe.
In one embodiment, the first thin plate is arranged on the inner side of the inner wall of the bridge pipe, the second thin plate is arranged on the outer side of the outer wall of the bridge pipe, and the first thin plate and the second thin plate are fastened on the bridge pipe by tightening the nut.
To sum up, the utility model discloses following beneficial effect has:
firstly, thin plates are respectively fixed on the inner wall and the outer wall of the bridge tube, and the damaged points of the bridge tube are repaired by bonding of welding rod layers, so that the replacement cost is reduced;
secondly, the safety risk caused by untimely replacement or maintenance can be eliminated by using the method;
thirdly, the labor intensity is reduced and the replacement cost is saved.
