BUTTERFLY VALVE |
摘要 |
This invention relates to a control valve of the butterfly-type which is capable of quickly and dependably stopping the flow of steam under high temperature and pressure in a large diameter conduit, such as may be used in conjunction with a steam turbine. After stoppage of the steam flow, the valve is capable of reopening against the full steam pressure drop built up across the valve.
