Bolt Shut-off Nozzle type BHP - pneumatic or hydraulic actuation. A shut-off bolt, positioned perpendicular to the melt channel moves up and down according to actuation, and thus shuts off/opens the melt flow. This nozzle type has a single melt channel. It therefore does not require rerouting of the melt around the shut-off mechanism.
Applied using eductor or compressed air foam system (CAFS) and pumped through fire hose to a foam nozzle (or sometimes a less-effective fog nozzle). Attack hose (Attack line) A use classification of a fire fighting hose connected to output of a pump or other pressure source (e.g., gravity). Fire hose used to apply water or other fire fighting ...
The valve is shut off at both its top and bottom positions. A second valve, placed within the main cylinder valve, releases the water in the topmost pressure chamber when the flush lever is activated, sending the main cylinder valve shooting upwards.
In water distribution systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, pipes freeze, or there is unexpectedly high demand on the water system (for example, when several fire hydrants are opened).
Convergent nozzles accelerate subsonic fluids. If the nozzle pressure ratio is high enough, then the flow will reach sonic velocity at the narrowest point (i.e. the nozzle throat). In this situation, the nozzle is said to be choked. Increasing the nozzle pressure ratio further will not increase the throat Mach number above one.
The devices allow air into the system to prevent a siphon at the point of use. Hose connection vacuum breakers are installed on faucets and hose bibbs to prevent backflow into the water supply. Pressure type vacuum breakers are similar to atmospheric vacuum breakers but have a spring-loaded check valve to allow operation of under pressure for ...
