The semicircular fixing pillar with the circular top end is arranged on the bottom face of the fixing platform on one side of the water draining outlet, the semicircular fixing hole is formed in the elastic detachable cap provided with the forming ring, and the fixing pillar is matched with the fixing hole to fix the detachable cap and seal the water draining outlet.

Description

Annular trap detachable cap floor drain

Technical field

The present invention relates to the pipeline field, is a kind of pipeline anti-reversing clutch specifically.

Technical background

The floor drain used at present is single siphon trap type or flap-covered, returns in defect, and the effect of anti-reverse flavor and anti-harmful insect is all undesirable, and flap-covered is perishable.

Summary of the invention

The objective of the invention is, trap structure and detachable cap structure are combined, overcome the bad and very stiff and demanding bad sealing of hard machinery detachable cap floor drain of the anti-reverse effect of current trap floor drain and hold flimsy defect, design a kind of annular trap detachable cap floor drain.

Technical scheme of the present invention is: a kind of annular trap detachable cap floor drain, comprise: grate frame, cannelure, notch, the L groove, lug, annular is recessed, inner core, outer tube, the lower mouth of a river, detachable cap, shaping ring, fixed leg, fixing hole, fixed station, the dash pipe, auricle, grate, it is characterized in that: outer tube coordinates one with grate frame, lug screws in the L groove is fixed as one inner core and grate frame, inner core is the centripetal recessed and lower mouth of a river of annular that is bent to form of serpentine, auricle screws in cannelure by grate from notch, grate frame is fixed as one, insert annular spill with the dash pipe of grate one and circularize trap, it is circular semicircle fixed leg that there is top the fixed station bottom surface of the lower mouth of a river one side, have on the elastic body detachable cap of shaping ring semicircle fixing hole is arranged, fixed leg coordinates with fixing hole fixes detachable cap and seals the lower mouth of a river.

During use, sewage flows into the trap that annular is recessed and the dash pipe forms of inner core by grate, then flow into the mouth of a river under inner core, when sewage weight surpasses the support force of detachable cap, detachable cap will be opened downwards, and after sewage passes through, detachable cap return under self elastic force effect makes floor drain in closed state.Trap and detachable cap play the dual effect that stops contrary back foul flavor and insect.

Adopt technique scheme, drain structure more advantages of simple, be not easy to damage, anti-reverse flavor and pest control effect are improved, thereby have guaranteed the sanitary cleaning of indoor environment, have reduced the harm to health of the propagation chance of insect-borne infectious disease and sewer odor.
