Abstract
The utility model discloses a high-temperature and high-pressure seal butterfly valve which comprises a valve body, a valve stem and a butterfly plate. The butterfly plate is arranged on the valve body, the valve stem penetrates the valve body to be connected with the butterfly plate, a pressure plate is further arranged on the valve body, a first sealing ring is mounted on the valve body in an inlaid manner and is butted to the butterfly plate, and the valve body is hermetically connected with the butterfly plate by the first sealing ring; a second sealing ring is mounted on the butterfly plate in an inlaid manner and is butted to the pressure plate, and the butterfly plate is hermetically connected with the pressure plate by the second sealing ring. The two sealing rings are respectively inlaid on the butterfly plate and the valve body, so that a primary elastic sealing effect can be realized for a space between the butterfly plate and the valve body under the contact squeezing effect of the first sealing ring and the butterfly plate when the butterfly plate is rotationally closed, and a secondary elastic sealing effect can be realized under the contact squeezing effect of the second sealing ring and the pressure plate; the excellent sealing performance of the butterfly valve can be guaranteed by the double sealing effects even in high-temperature and high-pressure service environments. According to the scheme, the high-temperature and high-pressure seal butterfly valve has the advantage that the butterfly valve can be sealed under high pressures, and can be reliably sealed at high temperatures owing to a metal design of a sealing surface of the valve.
