Description

Technical Field

[0001] The utility model relates to the technical field of quenching devices, in particular to a surface quenching device for a butterfly valve plate. Background Art

[0002] The butterfly valve is a common industrial valve with a simple structure, small size and light weight. It uses a butterfly valve disc as the opening and closing part. The butterfly valve disc rotates along the valve axis when the valve is opened, thereby changing the flow state of the fluid. The butterfly valve is usually used to cut off or regulate the fluid. It has the characteristics of fast opening and closing, small flow resistance and reliable sealing.

[0003] The main components of a butterfly valve include a valve body, a valve plate, a valve stem, and seals. The valve body is usually round or oval, with a flow channel inside. The fluid enters the valve body from one side and controls the flow through the valve plate. The valve plate is butterfly-shaped and is connected to a manual operating device or electric actuator through a valve stem to control the opening and closing of the valve. The seals usually include a valve seat seal and a valve plate seal to ensure the sealing performance of the valve.

[0004] During the production process of butterfly valve plates, the surface must be quenched by a quenching device to obtain high hardness and wear resistance.

[0005] In the prior art, when the butterfly valve plate is quenched, the positioning of the valve plate is not convenient enough, and it is not easy to quickly position and clamp the valve plate, which will affect the quenching efficiency. In addition, during the quenching process, when the heated valve plate contacts the quenching oil, a large amount of smoke oil impurities will be generated, which will cause harm to the external environment and human body. Therefore, improvements are needed. Utility Model Content
