By adopting technique scheme, the filter screen at filtration channel place can play the filtration to medium, when filtration, impurity is along the arc-shaped concave landing of feed pathway internal face to collecting dirty groove, impurity falls into drain outlet through collecting dirty groove, open sealing nut and can discharge fast impurity, simple in structure, impurity is removed convenient, and elimination efficiency is high; Stamping Steel Ribbon is set on flap makes flap sealability better.
The utility model is further set to: between described sealing nut and outer end, drain outlet, be provided with O-ring seals, described drain outlet is circular channel, and sealing projection is round bump, and sealing projection outer surface and drain outlet are sealed and matched.By this setting, between sealing nut and drain outlet, sealability is better.
The utility model is also further set to: described filter screen is stainless steel filter screen, and filter screen edge and filtration channel internal face are welded and fixed.By this setting, filter screen arranges rationally, connects reliable.
The utility model is also further set to: described Stamping Steel Ribbon arranges along flap edge, and Stamping Steel Ribbon is rubber weather strip.By this setting, Stamping Steel Ribbon position arranges rationally, good seal performance.
Model utility is also further set to: described fixed strip is stainless steel steel bar.By this setting, fixed strip structure arranges rationally, fixing reliable.
The utility model has the advantages that: compared with prior art, the utility model structure arranges rationally, the filter screen at filtration channel place can play the filtration to medium, when filtration, impurity is along the arc-shaped concave landing of feed pathway internal face to collecting dirty groove, impurity falls into drain outlet through collecting dirty groove, opens sealing nut and can discharge fast impurity, simple in structure, impurity is removed convenient, and elimination efficiency is high; Stamping Steel Ribbon is set on flap makes flap sealability better.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
