Brass vacuum break valve(1) When the following pipes
are directly connected from the domestic drinking water pipes in
the community or buildings, the vacuum breaker should be set on
these water pipes.a. When the air gap between the water filling
pipe outlet and the overflow water level of the swimming pool, the
upstream music pool, the Jacuzzi pool, the water feature pool, the
circulating cooling water collecting pool, etc., is less than 2.5
times the diameter of the outlet pipe, the vacuum breaker is
installed on the filling (filling) water pipeb. Green space
sprinkler irrigation without chemical agents? When the sprinkler
head is underground or automatic lifting type, install a broken
vacuum valve at the beginning of the water diversion pipec. Fire
fighting? (hose) reel;d. Outlet connection of hose flushing water
nozzle and water supply pipe.(2) A vacuum breaker and an exhaust
valve should be set at the top of the water supply riser.Brass
vacuum break valve working principleVacuum breaker is also known as
vacuum breaker valve or vacuum breaker valve or anti-negative
pressure valve, it is used to automatically eliminate the vacuum in
the water supply pipeline, effectively prevent siphon backflow,
eliminate backflow pollution. Backflow pollution has a great impact
on water quality, and even endangers life when it is serious.
Therefore, the current water supply code stipulates that vacuum
breakers must be installed. Commonly used vacuum breakers are
atmospheric type, pressure type and hose type. Our products are
common atmospheric vacuum breakers. The atmospheric vacuum breaker
can remove the vacuum by introducing the atmosphere when the
pressure in the water supply pipe is less than atmospheric
pressure. After the balance is reached, the system is automatically
closed, which protects the system.Brass vacuum break valve
application ***Used as steam heat exchange equipment protection,
after steam stop, due to the condensation of steam in the
equipment, forming a vacuum in the equipment and some components in
the system easy to cause damage to the equipment and the system,
the valve in the equipment vacuum reached a certain value,
automatically open, introduce air, eliminate the vacuum in the
equipment and the system to play a protective role in the equipment
and the system, in the normal operation of the equipment, it closed
tight, No fluid leakage is allowed, the vacuum can also be
controlled in a certain range, when the vacuum pressure rises to a
certain value will automatically open into the air, the vacuum
drops to a certain value will automatically close the air vent so
that the vacuum control in a certain range/* March 10, 2023
