AI Technical Summary
The existing safety valve body structure design makes it difficult to perform precision machining in narrow internal spaces, resulting in inconsistent machining accuracy of the sealing surface, affecting sealing performance and overall reliability, and increasing safety hazards in equipment operation.
The valve body is designed as a detachable inlet valve body and a detachable outlet valve body, with a detachable valve plate installed between them. The valve plate is machined with a sealing surface, combined with a stepped groove and a sealing ring, and fixed by a threaded sleeve to ensure the accuracy and stability of the sealing surface.
It reduces the machining difficulty of the valve plate sealing surface, improves the sealing performance and the overall reliability of the valve body, reduces maintenance costs and downtime, and ensures a reliable fit between the sealing surface and the valve disc.
