100MN多向模锻水压机操纵系统的主分配器阀口的装配与研磨是进水阀和排水阀装配中最重要的工序。研磨是为了提高阀座与阀α45°接触面均匀达75％以上的有效途径,也是提高阀的使用寿命,防止气蚀与磨损的一种有效方法。磨损是一种非常普遍的现象,凡是运动的零件,无论与金属或非金属接触,还是与流体接触都会产生磨损现象。这种现象,严重影响阀的使用寿命。减少磨损的办法有三种:(1) 改变阀体的本身材质;(2) 提高阀的硬度与耐磨性、防腐性;(3) 提高阀的配装精度。主分配阀阀口配装主要采用第3种方法,就是
100MN multi-die forging hydraulic control system of the main distributor Valve port assembly and grinding of the inlet valve and drain valve assembly of the most important processes. Grinding is to improve the valve seat and the valve α45 ° contact surface of more than 75% of the effective way, but also to improve valve life, to prevent cavitation and wear an effective method. Wear is a very common phenomenon where moving parts, whether in contact with metal or non-metal, or with fluid, can wear out. This phenomenon, seriously affect the service life of the valve. There are three ways to reduce wear: (1) to change the body’s own material; (2) to improve the valve hardness and wear resistance, corrosion resistance; (3) to improve the valve assembly accuracy. The main distribution valve port equipped with the first three methods, that is
