O Utility Model Registration Claims (1) An electron gun chamber that generates an electron beam in a high vacuum atmosphere, a welding chamber that welds objects to be welded in a low vacuum atmosphere, and between the electron gun chamber and the welding chamber. an intermediate chamber in which the welding chamber is located; a valve provided in the intermediate chamber for partitioning the electron gun chamber and the welding chamber to maintain a high vacuum in the electron gun chamber when the welding chamber is opened to the atmosphere; In the welding device, the welding device is provided with a cover that protects a valve seat facing the valve when the valve is in an open state; The cover is pivotably supported by the valve and moves away from and into contact with the valve seat in response to the valve coming into contact with and away from the valve seat, and the connecting member is rotatably coupled to the other ends of the valve and the cover, respectively. An electron beam welding device characterized by comprising: (2) - A rectangular rod body connected to the free end of a cover made of a plate-shaped body with colored sides, and whose ends on opposite sides of the - side are inserted into holes formed on both sides of the valve. An electron beam welding apparatus according to claim 1, comprising a connecting member comprising:

Claims

[Scope of utility model registration request]

(1) An electron gun chamber that generates an electron beam in a high vacuum atmosphere, a welding chamber that welds objects to be welded in a low vacuum atmosphere, and an intermediate chamber located between the electron gun chamber and the welding chamber; A valve is provided in the intermediate chamber and partitions between the electron gun chamber and the welding chamber in order to maintain a high vacuum in the electron gun chamber when the welding chamber is opened to the atmosphere, and the valve is in an open state during welding. In a welding device equipped with a cover that protects a valve seat facing the valve, the valve is rotated by an actuator to contact and separate from the valve seat, and the valve has one end pivoted in the intermediate chamber. The valve is characterized by comprising: the cover that comes into contact with and away from the valve seat in response to coming into contact with and separating from the valve seat, and a connecting member rotatably coupled to the other ends of the valve and the cover, respectively. Electron beam welding equipment.

(2) - A rectangular rod body connected to the free end of a cover made of a plate-shaped body with colored sides, and whose ends on opposite sides of the - side are inserted into holes formed on both sides of the valve. An electron beam welding device according to claim 1, comprising a connecting member comprising:
