Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As illustrated in fig. 1 and 2, a kind of straight-through type filter, including：Housing 1, steering gear 2, filter cylinder 3, backwash valve plate 4, pressure difference
Switch 5 and blowoff valve 6, the two ends of housing 1, which are respectively arranged with water inlet 7 and delivery port 8, water inlet 7 and delivery port 8, to be respectively provided with
There is adpting flange 9, the inner side close to the housing 1 of water inlet 7 is provided with backwash valve plate 4, is set between backwash valve plate 4 and delivery port 8
