The reduction of the air friction in the valve is similar to expanding of the valve, which increases the air coming in and out. 在气门壁面流动的空气阻力变小,就好像把气门加大一样,而使得吸气量与排气量增加。
Application of Steam Pressure Reduction Valve in Sulfuration System of Textile Rubber Accessories 蒸汽减压阀在纺织橡胶器材硫化系统中的应用
The results show that improving the rolling velocity and reducing the galvanizing time will result in reduction of strength loss after galvanizing, and increase of bend torsion valve, thus productivity is improved. 结果表明:提高收线速度,减少浸锌时间,镀后强度损失减小,弯扭值提高,生产效率提高。
Engine noise source identification is essential for making noise reduction strategies. Predominant noise sources of engines are normally identified as some cover components such as oil pan, valve cover and front gear cover etc. 发动机噪声源识别对于制定发动机降噪措施十分重要,而像油底壳、气门罩、前齿轮室盖等罩壳类零件通常是发动机的主要噪声源。
In the meantime, its sensibility becomes higher due to reduction of friction and adhesiveness by automatically rotation of valve sleeve. 同时,由于阀套自动快速旋转,减少了静摩擦和粘滞影响,提高了灵敏度。
Conclusion: The pathological damages of rheumatic myocardium and the reduction of their heart functions were more significant in valve insufficiency group, but myocardial work and load increased. 组1死亡1例。结论瓣膜关闭不全型的风湿性心肌病理损害及心功能下降更为明显,心脏负荷及心肌作功反而增加。
The flow diagram is transformed into new complex plan with conformal mapping and then the deflection angles and reduction coeficient of injection with different valve port angles and different relative sizes can be found by using source and sink distribution method. 本文利用源、汇分布法,通过将流动平面保角映射为新的复平面而得到了在不同阀口角度、不同阀口相对尺寸时射流的偏转角与射流的收缩系数。
