High temperature resistant tee bend relief valve Technical Field The application relates to the technical field of valves, in particular to a high-temperature-resistant three-way discharge valve. Background The three-way distributor is an industrial device, is mainly used for material reversing and flow dividing processes, and controls turning plates to turn over by driving a rotating shaft mechanism of the three-way distributor through an electro-hydraulic push rod so as to achieve the effect of material reversing. Most of the existing tee distributor shells are made of carbon steel, and are only suitable for normal-temperature materials. For the high-temperature working condition, although the distributor shell is made of stainless steel, the upper temperature resistant limit is only 500 ℃, and the working condition requirement of higher temperature cannot be met. In addition, in order to cope with higher temperature, some conventional water-cooling discharge valves (rotary valves) adopt a water-cooling mode, and a transmission shaft and a bearing are protected through cooling water circulation, so that the temperature resistance of the equipment can reach 800 ℃. However, although the water cooling design is effective in the conventional rotary valve, mechanical parts of equipment can be effectively protected, the water cooling design cannot realize the multi-channel material distribution function, and the requirement of multi-channel distribution of materials under the high-temperature working condition cannot be met.
