The knowledge of the pneumatic valve

from the gas in the working principle of the pneumatic valve, pneumatic pneumatic valve performance will directly affect the work of the compressor cylinder, therefore, the gas pneumatic valve has the following requirements: resistance losses small. Gas pneumatic valve size and airflow resistance losses of valves always speed and the size of the spring-loaded edge. The higher the gas velocity, the greater the energy losses; Spring force is too large, the loss is great resistance, the size according to the gas air valve movement design guidelines to determine the reasonableness of the law. Gas air valve closed timely, rapid, not leak closed, to improve the efficiency of the machine, prolong life. Long life and reliable operation. Life is the main factor of restricting air pneumatic valve pneumatic valve plates and the spring quality, the general long-term continuous operation of the compressor, hope life over hours or more; For mobile, shortness of breath, pneumatic valve is an important part in reciprocating piston compressor, is also one of the components easily damaged. It's good or bad a direct impact on the displacement compressors, power consumption and reliability of operation, the current compressor is fast direction, and rotational speed limit is one of the key issues in improving air pneumatic valve. Piston compressor is generally adopts automatic pneumatic valve, pneumatic valve is the gas is open and close the pneumatic valve on the pressure difference on both sides of the implementation, there is no other drive mechanism. Period or intermittent operation of compressors, may require slightly more. 从气阀工作原理来看,气阀性能将直接影响压缩机气缸的工作,空气阀以下要求:阻力损失小。 空气阀的阀门通径和气流阻力损失总是速度和弹簧的尺寸 加载的边缘。 气速越高,能量损失越大; 春天, 加载边太大,阻力损失也大,空气阀运动的大小设计准则来确定法律的合理性。 气阀关闭及时、迅速,关闭不漏气,以提高机器的效率,延长使用周期。 寿命长、工作可靠。 生活的主要因素——限制空气阀和春天 加载阀质量,一般长 术语压缩机生活小时的连续操作; 为移动,短期 词或间歇运行的压缩机,可能需要稍多。 空气阀和活塞 类型压缩机的重要部件易损坏的部件之一。 它将直接影响压缩机的排气量、功耗和可靠性的操作,当前压缩机快方向,旋转速度限制是改善空气阀的关键问题之一。 活塞, 类型压缩机通常使用自动阀的空气阀的开启和关闭阀门两边的压力差实现,并且没有其他驱动器。
