贵刊1983年第2期刊登侯铎同志的<容积式和节流式同步装置及其在热轧机上的应用>一文中,关于分流集流阀端弹簧的作用(见原文)商榷如下: 根据我们设计多种型式分流集流阀和使用该阀的经验来看,端弹簧不具备该文提出的四条作用。第一,同步阀不是换向阀,不能控制油路方向,调整端弹簧不能使油缸往返运行。第二,关于换向时间问题,不论外负载有无偏差,只要是从分流工况变为集流工况(反之亦然),换向阀芯均有一个换向
In your article No. 2, 1983, Comrade Hou Duo published a book entitled “Volumetric and Threaded Synchronization Devices and Their Applications in Hot Rolling Mills”, on the role of shunt current-collecting end springs (see original) We design a variety of types of diverter manifold valve and the experience of using the valve, the end of the spring does not have the four effects of the proposed. First, the synchronization valve is not a valve, can not control the direction of the oil, adjust the end of the spring can not make the cylinder back and forth. Second, with regard to the commutation time, regardless of whether there is no deviation of the external load, as long as it is from the diverting condition to the collecting condition (or vice versa), the reversing valve element has a commutation
