It is fixed.
Preferably, closeouts or switch member (not shown) are provided with the bath joint 4, in the course of normal operation of filter core
In, namely when filter cartridge flushing is not needed, the joint 4 that be able to will be washed by water by closeouts or switch member is closed, and avoids the occurrence of water
Leakage.And when needing to be rinsed filter core, then the closeouts that can dismantle or opening switch member enable flushing water suitable
Profit enters in flush pipe 3.
Preferably, entrance one end of the bath joint 4 is provided with fast connection interface, so as to when needing to connect flushing water source
The pipe fitting such as PE pipes can be quickly plugged on bath joint 4, so as to rapidly start flushing process.
Preferably, axially disposed in the side wall of the flush pipe 3 to have multiple row hole for water spraying 31, multiple row hole for water spraying 31 preferably exists
It is evenly arranged in circumference, meanwhile, each column hole for water spraying 31 is for example including evenly-spaced multiple hole for water sprayings 31, as shown in Figure 3.This
Sample, in specific rinse, it can be sprayed water in the length range of flush pipe 3 and in the range of 360 degree, so as to as far as possible
Filter material is rinsed in big scope, strengthens developing result.
Preferably, the aperture of the hole for water spraying 31 is gradually reduced on water spraying direction, it is possible thereby in the mistake of hydroblasting
Have the function that supercharging in journey, the pressure differential of surface of filter medium, more strength area are walked to pollute impurity when increase is rinsed, and further improve
Developing result.
The upper end (i.e. free end) of flush pipe 3 can be blind end, or plugging structure is set near upper end, to prevent
Flushing water directly vomits from upper end.
Preferably, as shown in figure 3, at least a portion in multiple row hole for water spraying 31 in the side wall of the flush pipe in a ring
Arrangement, the one group of hole for water spraying 31 arranged in a ring to surrounding all directions while can spray water on sustained height, developing result
Preferably.
