bleed valve การใช้

• To bleed a radiator, first position a pan under the bleed valve.
• There are several advantages in using a Double Block and Bleed Valve.
• They usually have a manual bleed valve or screw.
• Place a pan under the radiator bleed valve and open it with a radiator key.
• A dislodged tarpaulin had blocked the bleed valve on the satellite container and the spacecraft had suffer from over pressurization damage.
• The crew was uncomfortable because of the cold, although the heater's engine bleed valve to draw additional hot air into the heater from the engine manifold.
• The undercarriage bounce took more time to solve but eventually a " bleed valve " incorporated in the legs allowed the hydraulic pressure to be released gradually as the aircraft landed.
• Depending upon the type of bleed valve, you can use either a screwdriver or a radiator key ( available at hardware stores or plumbing supply stores ) to open the valve.
• With that, the right engine anti-ice start bleed valve being in the open position lead to a 13 % torque split between the two engines and a yaw-effect when not compensated for.
• But it sounds like you have one of those naff blown-air heating systems popular in north america, so I guess it's air in the heat-exchanger pipes instead ( and again it should have a bleed valve ).
• Although the operating pressure was maintained by an automatically controlled bleed valve once the plant had reached steady state, the valve could not be used during start-up, when there was no air feed, the plant being pressurised with nitrogen.
• In the Space Shuttle the main oxidizer and fuel bleed valves were used after shutdown to dump any residual propellant, with residual liquid oxygen venting through the engine and residual liquid hydrogen venting through the liquid hydrogen fill and drain valves.
• During start-up the bleed valve was normally isolated and there was no route for excess pressure to escape; pressure was kept within acceptable limits ( slightly wider that those achieved under automatic control ) by operator intervention ( manual operation of vent valves ).
