High-temperature-resistant sealing structure and regulating valve with same

The utility model relates to a high temperature resistant sealing structure and a regulating valve with the sealing structure, which comprise a sealing ring and sealing grooves arranged on a valve cover and a valve body, when the valve cover and the valve body are spliced, the two sealing grooves are spliced to form a sealing cavity, the sealing ring is arranged in the sealing cavity, a guide part is arranged on one side in the sealing cavity, and the guide part is arranged on the other side in the sealing cavity. A positioning part is arranged on the first side of the sealing ring, and the guiding part extrudes the sealing ring through the positioning part so that the second side of the sealing ring can abut against the side walls of the two sealing grooves. When the valve body or the valve cover deforms, the sealing ring keeps abutting against the side walls of the two sealing grooves at the same time, and the sealing performance between the valve cover and the valve body can be guaranteed. 本实用新型涉及一种耐高温的密封结
