Problems solved by technology

Adapting to high temperature operation is also a difficult technology for butterfly valve applications, especially in the operating conditions that require a cut-off function, because sometimes the temperature of the circulating medium is extremely high, and the axial ends of the valve are elongated, thereby driving the valve plate installed on it. Displacement along the axial direction, due to the change in position, the sealing ring of the valve plate is closely attached to the valve seat, and finally the valve plate cannot be opened

Abstract

The invention discloses a coal-to-hydrogen high-pressure butterfly valve in hydrogen service. The coal-to-hydrogen high-pressure butterfly valve comprises a valve body (1), a valve plate (2) and a valve shaft (3). Positioning rings (8) are arranged in small holes of stepped holes. Supporting and sealing assemblies are arranged in large holes of the stepped holes. A spherical groove (15) is formedin a spherical joint outer ring (10). A spherical joint inner ring (9) capable of rotating around the axis of the spherical groove (15) is arranged in the spherical joint outer ring (10). Flat keys (17) arranged in the axial direction are installed on the valve shaft (3). The left end portion and the right end portion of the valve plate (2) are pressed between the two positioning rings (8) in an abutting manner. A seal ring (19) matched with a conical valve seat (5) is installed on the outer ring of the valve plate (2). The coal-to-hydrogen high-pressure butterfly valve has the beneficial effects that operation is reliable, emergent sealing can be conveniently implemented, it is effectively avoided that the valve shaft gets stuck by medium particles, the service life is long, the sealing tightness is ensured and the valve shaft is flexibly started and stopped.

Description

technical field [0001] The invention relates to the technical field of hydrogen-facing butterfly valve structures, in particular to a high-pressure hydrogen-facing butterfly valve for coal-to-hydrogen production. Background technique [0002] High-pressure butterfly valves have always been a technically difficult product in the field of butterfly valves, mainly related to the support strength and stiffness of the valve, the opening and closing force of the valve and other aspects of technology. At present, with the large-scale development of various industrial devices, large-diameter high-pressure differentials have become the mainstream of device valve development. Adapting to high temperature operation is also a difficult technology for butterfly valve applications, especially in the operating conditions that require a cut-off function, because sometimes the temperature of the circulating medium is extremely high, and the axial ends of the valve are elongated, thereby driv...
