valve-seat contact

The article introduces the principle and features of contact box valve mechanism of Type KYN 61-40.5 movable high-voltage switchgear cabinet.

介绍KYN61-40.5移开式高压开关柜的触头盒活门机构原理及特点。

Hydrodynamic behavior of HY-Contact valve tray has been studied on a 1000 × 150 mm2 rectangular laboratory tray model by using air and water.

本试验以空气-水为介质，在1000×150mm~2长方形截面塔中进行了锥心浮阀塔板的流体力学初步研究。

The shape changes are transferred to tool rest by the contact of slide valve, then the parts needed are processed.

靠模通过与滑阀相连接的触头将外形变化传递给刀架，从而加工出所需零件。

The contact and the gas valve are controlled by phototriac and triac.

用光耦和双向晶闸管控制接触器和电磁阀。

Based on the calculation, after using the hydraulic tappet, the valve train not only has less vibration and noises but the cam contact stress has been improved obviously.

经计算，使用了液压挺柱后，不仅振动和噪声减小，而且凸轮与挺柱接触应力也有明显的改善。
