‧ The flow-directing mechanism, in the valve, has
the functions of flow-guiding and pressure-stabilizing.
‧In the corner of pipe, the water hammer is the most
obvious. The design is for meeting the requirement
and set the arrestor at the corner directly. This design
not only saves the space and is easy to set up, and also
can replace the traditional crooked head to reduce the
cost of setting up.
‧L style has the double way water-hammer-absorbing
and has excellent results.
‧Patent Number : 131907
‧The test pressure of valve body
Bronze : 12 kgf/cm2
cast iron: 21kgf/cm2
stainless steel : 35kgf/cm2
‧The applied conditions : normal fresh fluid
‧Applied temperature:-15 ℃～80 ℃
‧If the diameter is large than 2", stainless
steel valve is available.
‧If the fluid is acid/base or oil, the air bag
made of special material should be applied. |

When and where should the L style water hammer arrestor be set up?
When
the pump shut off, the pressure decrease instantly and
cause the unstable positive and negative pressure gap which
cause water hammer effect and create noise and pipe vibration.
To set up water hammer arrestor at the pipe corner upside of
the pump (shown as the figure) can prevent the water hammer
effect and protect the machine.
‧Remark:
When lift is longer than 50m and pressure
is 5 kgf/cm2,
we
suggest to set up arrestors each at the downside of the long
pipe and the corner upside of the check valve.
|
 |
|
It's easy to cause water hammer effect when
the
valve close fast. To set up arrestor at the first
corner away from the fast-shut-down valve can
absorb and prevent the water hammer effect
directly and eliminate the noise.
|
silent check valve
When the fluid flow through the serial corner, the
change of flow speed and direction and friction
effect will cause unstable pressure wave, which will
lead to vibration and noise. To set up arrestor and
silent check valve can eliminate the pressure wave.
|
‧Remark‧
‧The pressure meter on the valve will show the air chamber pressure
before piping and show the pipe
pressure after piping.
‧To leave a 10 cm opening between valve and wall for easy to maintain.
‧Considering the high-pressure situation, cast iron or stainless
steel valve body is suggested for the valve
whose diameter is larger than 2".
‧When lift is longer than 50 m and pressure is 5 kgf/cm2,
we suggest to set up arrester each at the downside
of the long pipe and the corner upside of the check Valve.
‧Before setting up, make sure the pressure of water hammer arrester
air chamber cannot be higher than
pipe pressure.
‧When the pressure of the air chamber of the water hammer arrester
is maintained at the 60% ~ 90% of pipe
pressure, the arrester will have the best water-hammer-preventing
result.
‧If the water pressure in the pipe is too low or the air pressure
of the arrester air chamber is too low. Both
can be corrected by pumped into air or release air from the air-pumping
hole at the top of the arrester.
‧When the Outlet is under open pressure like float valve, bathroom
equipment and faucet, input pressure
1 ~ 1.3 kgf/cm2
is preferred.
