Abstract
The utility model relates to the technical field of a valve, in particular to a novel anti-leakage valve seat ultra-low temperature valve. The novel anti-leakage valve seat ultra-low temperature valve is characterized by comprising a valve body, a valve seat seal, a flashboard, a valve rod, a valve rod sleeve, a lower sealing pad and a seal. According to the novel anti-leakage valve seat ultra-low temperature valve, the valve seat seal is arranged on the flashboard to prevent a valve seat from being broken and causing leakage.
Description
Technical field
