Connected between chamber by the first fluid-through tube and the second fluid-through tube, filter core, one end of the filter are provided with the filter
It is provided with liquid outlet；
Be provided with reversal valve on the pipeline, the filter by the control of reversal valve and present normal operating conditions or
Backwashing state；
During normal operating conditions, the pipeline connects with the first fluid-through tube, and liquid flows into from the inlet, by described
First fluid-through tube is flowed into filter core, is flowed out from the liquid outlet；
During backwashing state, the pipeline connects with the second fluid-through tube, and liquid enters filter from second fluid-through tube
Cavity in, after first fluid-through tube, from impurity outlet flow out.
The reversal valve is ball valve, and the upper surface of the controller is provided with the handle of control ball valve direction, so as to adjust
The position of ball valve.
The inlet, liquid outlet and impurity outlet are provided with the joint being connected with extraneous pipeline.
The shading ring for preventing that the first fluid-through tube from directly communicating with the second fluid-through tube, institute are provided with the inwall of the filter
Stating shading ring makes liquid to enter filter core, then enter the first fluid-through tube from the filter core after the second fluid-through tube enters filter.
The handle is provided with gag lever post with the hinged place of controller, and the gag lever post causes handle in the scope of restriction
Inward turning turnback.
The utility model has the advantages that compared with prior art：
1st, the present apparatus adjusts the flow direction of liquid using reversal valve, so as to realize two kinds of functions of normal filtration and backwash,
When needing filtering, inlet and liquid outlet are connected by reversal valve, now liquid enters inlet, by filter core from liquid outlet
Outflow, reaches filtering function, when backwashing is desired, connects inlet and impurity outlet by reversal valve, liquid is by outside filter core
Impurity flows out from impurity outlet.
2nd, the present apparatus is gone out the impurity outside filter core using backwashing function, is gone out so as to prevent filter core because of long-term use of
The problem of existing impurity accumulation, also extend the service life of filter core.
3rd, the present apparatus is simple in construction, and controller only need to be added in the technology of original filter, and simple to operate, subtracts
Lack the work of artificial unloading's cleaning, it is time saving and energy saving.
