AI Technical Summary
Technical Problem
[0003]在现有技术中，特别是在粉料传输等耐磨领域，阀门采用金属阀座和金属阀芯的组合，但使用寿命较短；阀门采用硬质材料阀座和金属阀芯的组合，金属阀芯寿命短，使用范围受限；阀门采用硬质材料阀座与金属阀芯连接阀芯硬质材料内衬的组合，硬质材料阀座在高压下易断，硬质材料使用较多，加工难度增加，成本偏高
Benefits of technology
[0006]本实用新型的工作原理及有益效果是：在粉料传输中，特别是高压条件下，需要较好的耐磨性能和较高的承压能力，金属阀座具有较高的承压能力，不易断裂，金属阀座内设置的阀座硬质材料内衬，具有较好的耐磨性，而且有较厚的厚度，提高了阀座装置的使用寿命；同时，阀座硬质材料内衬的材料使用较少，加工要求不高，使得阀座装置的成本大大降低。

Abstract
The utility model relates to the technical field of valve, specifically relates to a ball valve seat device, and with the valve core device cooperation uses, valve seat device includes metal valve seat and valve seat hard material lining, in the switch process of valve, the valve seat sealing surface of metal valve seat is used for with the valve core sealing surface of metal valve core abuts, be equipped with valve seat hard material lining in metal valve seat for powder transmission, in powder transmission, especially under high pressure condition, need better wear resistance and higher pressure capacity, metal valve seat has higher pressure capacity, is not easy to break, the valve seat hard material lining that sets up in metal valve seat, has better wear resistance, and has relatively thick thickness, has improved the service life of valve seat device, simultaneously, the material use of valve seat hard material lining is less, and the processing requirement is not high, makes the cost of valve seat device greatly reduces.
