Specific embodiment

The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below:

Referring to FIG. 1, a kind of y-type filter strainer with keel, for filtering impurity in fluid, including grid keel 10 With multiple tongue nets 20.

Referring to FIG. 2, grid keel 10 are annular shape, extending direction of the grid of grid keel 10 at both ends is linear Arrangement, integrally to provide good rigidity, the not easy damaged of the impact by turbulent fluid.

Referring to FIG. 3, tongue net 20 includes four walls 21 of support and wet end 22, four walls 21 of support are in put outward with wet end 22 Shape distribution is penetrated, multiple tongue nets 20 are embedded in the grid of grid keel 10, the cell walls mistake of support four wall 21 and grid keel 10 Mating connection of being full of can also be replaced, nothing convenient for later period detachable maintaining even if by impact failure by the part of disassembly damage Entirety, save the cost need to be replaced.

Wet end 22 is in arc-shaped, the curved surface radian that the curved surface radian that wet end 22 is constituted grid corresponding with grid keel 10 is constituted It is identical, it combines together after tongue net 20 is installed with grid keel.

Tongue net 20 includes the fixation lug 23 for claiming setting to two, offers fixation hole 24 in the middle part of fixed lug 23, fixed Lug 23 passes through fixation hole 24 by fastener and tongue net 20 is fixed on grid keel 10.Enhance tongue net 20 and grid dragon The tightness connected between bone 10.

The fixation lug 23 of adjacent tongue net 20 overlaps each other fixation, and row's tongue net 20 is made to constitute an entirety, enhancing Its integrally-built rigidity.

Referring to FIG. 4, the present embodiment also provides a kind of y-type filter with keel, including main pipeline ontology 30, main pipeline Ontology 30 is equipped with water inlet 31, water outlet 32 and inclined sewage draining exit 33.Group is equipped with outside sewage draining exit 33 without cover board 40.

It simultaneously further include that the y-type filter strainer with keel, the y-type filter strainer with keel are set to supervisor as the aforementioned Inside road ontology 30, the y-type filter strainer both ends with keel are separately connected water inlet 31 and sewage draining exit 33, and with blowdown cover board 40 contact, and water inlet 31 is connected by tongue net 20 and water outlet 33, and then the y-type filter strainer with keel can be to water inlet The water flows that mouth 31 enters are filtered, and filtered impurity stays in the y-type filter strainer with keel, and clear water then passes through water outlet Mouth 33 is discharged.

Blind plate 41 is equipped between blowdown cover board 40 and y-type filter strainer with keel, when user opens blowdown cover board 40 When impurity will not immediate inclination and go out；Blind plate 41 can prevent impurity from entering sewage draining exit 33 and group without the seam between cover board 40 simultaneously Gap.

Angular range between sewage draining exit 33 and main pipeline ontology 30 is 30 ° to 60 °, by above-mentioned angle convenient for impurity row Out.

Main pipeline ontology 30 is recessed far from 33 one side wall of sewage draining exit to 33 side of sewage draining exit, and water flow is made to change direction, buffering Rapid stream avoids torrent from directly colliding tongue net 20.

The utility model provides a kind of y-type filter strainer with keel, and grid keel are annular shape, the grid of grid keel Lattice are linearly arranged in the extending direction at both ends, provide good rigidity to be whole, the not rapid wear of the impact by turbulent fluid Wound；Tongue net includes four walls of support and wet end, and four walls of support are distributed with wet end in shape radially outward, and multiple tongue nets are embedded in net In the grid of lattice keel, the cell walls of four walls of support and grid keel, which are interference fitted, to be connected, and is convenient for later period detachable maintaining, even if by Impact failure can also be replaced by the part of disassembly damage, save the cost whole without replacing.

Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this The spirit and scope of utility model technical solution.
