Description

Technical Field

[0001] The utility model relates to the technical field of one-way valve core processing, in particular to a one-way valve core processing clamping structure. Background Art

[0002] A one-way valve, also known as a check valve, is an automatic valve whose main function is to allow the medium (liquid or gas) to flow freely in one direction while preventing the medium from flowing in the opposite direction. One-way valves are widely used in various hydraulic and pneumatic systems to control flow direction, protect pumps and drive motors from reverse damage, and prevent the release of container media.

[0003] The one-way valve core is the valve core of the one-way valve. Depending on the type of one-way valve, the type of valve core is also different. For example, a plate-type one-way valve uses a one-way valve core with a sealing plate on one end.

[0004] In the processing of the one-way valve core, it generally needs to undergo precise turning before being put into use. During the processing, a clamping structure is needed. The commonly used clamping structure is the three-jaw chuck.

[0005] However, since the one-way valve core is often provided with a large-sized plate body at one end, that is, a valve plate is integrally formed therewith, during processing, only one end of the valve core can be clamped. When processing the other end, the valve plate is too large to be clamped, which brings inconvenience to the user. Utility Model Content
