Hydraulic safety valve is used as standby
equipment of breather valve. The pressure of inhaling and exhaling is higher
than breather valve. When breather valve fails or disc is frozen in the winter,
liquid seal of hydraulic safety valve will be destructed to avoid oilcan being
damaged. Hydraulic safety valve is installed at the top of oilcan, being used
with breather valve.
