Abstract

The invention relates to a low flow resistance and high pressure pneumatic damping ball valve with a self-locking function, comprising an inlet shell, a flow guiding sleeve, a sphere and an outlet shell. The inlet shell is sleeved outside the flow guiding sleeve and connected with the outlet sleeve. The sphere is arranged between the flow guiding sleeve and the outlet sleeve. The low flow resistance and high pressure pneumatic damping ball valve further comprises a high-pressure air source, a pneumatic rotating-shaft component, a pneumatic lockpin component and a pneumatic valve component. According to the low flow resistance and high pressure pneumatic damping ball valve, the technical problems that the existing pneumatic control ball valve needs to be maintained by external energy after being opened and has requirements on control pressure and use occasion are solved. The pneumatic damping ball valve with small low diameter reduction ratio, low flow resistance and high pressure and with the self-locking function is used for controlling the opening and the closing of a liquid pipe in a liquid pipe control system.

Description

technical field [0001] The invention relates to a device for controlling the circulation and shutoff of a fluid medium, in particular to a control system for fluid pipelines with large flow and low flow resistance in the fields of modern aviation, aerospace, petrochemical, energy, power and the like. Background technique [0002] In liquid control systems in the fields of modern aviation, aerospace, petrochemical, energy, power, etc., ball valves are widely used valve products to control the flow and shut-off of fluid media. At present, the pneumatic control ball valve needs external energy to maintain after it is opened, and has certain requirements for control pressure and application occasions, and is not suitable for large vibration occasions. [0003] For this reason, it is necessary to develop a pneumatic control that can automatically maintain the open and closed state, and can realize remote control. After opening, it can maintain the open or closed state for a long ...
