Part II Rubber flexible Check valve
Product introduction
XF rubber slowly-closing cut-off valve is a new water supply and
drainage valve with full rubber structure, duck-mouthed appearance
and functions of positive flow-in and reserve cut-off. According to
thrust analysis and calculation as well as different operation
conditions, it is manufactured with different design mechanism and
different rubber products by special processing, At positive
operation the water flow inform entrance and the valve will be open
at weak hydraulic pressure. the hydraulic pressure is higher .the
valve gate will open more greatly and the water flow is greater ,At
reserve operation, the valve gate closes naturally and seals
tightly cut-off valve, the back pressure is higher, the valve gate
closes more tightly and the seal effect is better. It is used
widely in various drainage exits to prevent from pouring backwards
and flowing backwards in city planning, water conservancy and
sewage disposal etc, it is the ideal product to replace flap
valve.
Product characteristics:
The advantages are specially marked in comparison with traditional
flap valve:
a) Open and close automatically in security and reliability
according to hydraulic difference without noise and in no need of
operator and maintenance.
b) Positive start has little water resistance and start-up pressure
and the flow can be adjusted naturally according to hydraulic
pressure.
c) Reserve cut-off has good seal without leakage to prevent from
flowing backwards. the back pressure is higher and the effect is
barrier.
d) Anticorrosion, aging resistance, deformation resistance, strong
adaptability and long use life
e) Wide size scope, nominal diameter of DN**-DN***0.
Application scope:
- Excellent performance and wide application scope
- Applicable for sewage system
- Applicable for discharge system
- Applicable for dyke discharge
- Applicable for the drainage of airport and freeway
- Applicable for sewer discharge
- Applicable for sewage lagoon discharge
- Smell separation
Installation structure type
1) Belled XF-T be installed at the exit of drainage pipe
2) Flanged XF-T be installed at the exit end with flange of
drainage pipe
3) Mounting plate XF-F is installed on the building at the water
exit end.
4) Build-in XF-F is installed at the exit end of rain and sewage
system in cities.
5) Grout or cement pipe XF-T be installed at the end of grout or
