Description
Technical Field
The utility model relates to a valve barrel technical field, concretely relates to durable valve barrel.
Background
The hydraulic valve is an automatic element operated by pressure oil, is controlled by the pressure oil of a distribution valve, is usually combined with an electromagnetic distribution valve for use, and can be used for remotely controlling the connection and disconnection of oil, gas and water pipeline systems of hydropower stations. It is commonly used for oil circuits of clamping, controlling, lubricating and the like. The direct-acting type and the pilot type are divided into a multi-purpose pilot type. The hydraulic drive is used to control the hydraulic pressure, flow and direction. Among them, a pressure control valve for controlling pressure, a flow control valve for controlling flow, and a directional control valve for controlling on, off, and flow directions are called. The valves are classified into relief valves, pressure reducing valves, and sequence valves according to their purposes. 1. An overflow valve: the hydraulic system can be controlled to keep a constant state when the set pressure is reached. Relief valves used for overload protection are known as relief valves. When the system is in failure and the pressure rises to a limit value which can cause damage, the valve port can be opened to overflow, so as to ensure the safety of the system. 2. A pressure reducing valve: the branch circuit can be controlled to obtain a stable pressure lower than the main circuit oil pressure. The pressure reducing valve is different according to the pressure function controlled by the pressure reducing valve, and can be divided into a constant value pressure reducing valve (the output pressure is a constant value), a constant difference pressure reducing valve (the pressure difference between the input pressure and the output pressure is a constant value) and a constant ratio pressure reducing valve (the input pressure and the output pressure are kept in a certain proportion). 3. A sequence valve: after one executive component (such as a hydraulic cylinder, a hydraulic motor and the like) acts, other executive components act sequentially.
The valve sleeve is a core conversion element of the servo control system, and the performance index of the valve sleeve directly influences the precision and stability of the whole control system. Therefore, the machining precision index of the valve sleeve has important significance. The traditional valve sleeve has poor stress relieving capability, so that the valve sleeve is easily damaged, and the service life is shortened.
