Problems solved by technology

[0003] However, due to the limited performance of ceramic materials, the ceramic parts in full-lined ceramic ball valves do not perform well in dealing with high thermal shock. Although the performance of different formulations varies, the overall situation appears to be insufficient. Therefore, in high thermal shock conditions. If the ceramic ball valve is to be applied, the problem of thermal shock must be solved

Abstract

The invention relates to a full-lining ceramic ball valve special for thermal shock. The full-lining ceramic ball valve comprises a valve body, a valve base body and a ball body, wherein the valve base body and the ball body are both ceramic bodies, the ball body is arranged in the valve base body, the valve base body is arranged on the inner wall of the valve body, a heating device is sleeved on the outside of the valve body, and a heat-conducting lining is arranged between the valve body and the valve base body. The full-lining ceramic ball valve special for thermal shock is simple in structure, and good in high temperature impact resistance and heat preservation effect, and the ceramic inner wall can be uniformly heated.

Description

technical field [0001] The invention relates to a ball valve, in particular to a ceramic ball valve. Background technique [0002] In various industries, harsh working conditions such as strong corrosion, strong erosion, and high wear have higher and higher requirements for valves, and the shortcoming of metal valves has become increasingly prominent. Traditional metal valves have been difficult to meet the needs of the system for stable operation. Due to the physical characteristics of ceramics, ceramic valves have the advantages of high temperature resistance, wear resistance, erosion resistance, corrosion resistance, etc., and are gradually replacing the application position of metal valves in a stormy trend. [0003] However, due to the limited performance of ceramic materials, the ceramic parts in full-lined ceramic ball valves do not perform well in dealing with high thermal shock. Although the performance of different formulations varies, the overall situation appears...
