Abstract
The utility model discloses a reducing self -closing floor drain core. This floor drain core includes opening, water conservancy diversion portion, transition portion and the closed portion of a body structure, and its structural feature is the top that the opening lies in water conservancy diversion portion, and closure portion connects in the bottom of water conservancy diversion portion through transition portion, the transition portion diameter of wide department is greater than the diameter of opening and water conservancy diversion portion, closure portion comprises two laminatings closed piece together, transition portion form by the upper segment and the hypomere of a body coupling, upper segment and hypomere are the gradual change circular arc cylindric that the upper end opening is big, the lower extreme opening is little, and the upper segment the diameter of wide department be greater than the diameter of opening and water conservancy diversion portion. The utility model has the advantages of the displacement is big, sealing performance good, be particularly useful for small -bore drowning mouthful.
Description
Technical field
The utility model relates to a kind of floor drain core, especially a kind of reducing self-closing floor drain core.
Background technology
Existing odour-proof floor drain mainly contains bell-jar, turnover plate type, hydrolock, T-shaped sealing deodorization formula, and wherein bell-jar is limited to and uses region, and the place as seldom lower water such as the dry districts beyond balcony, shower area, washroom uses, and can not play any deodorization effect; As long-term nobody home, the drawback that hydrolock also has dry rear odor-resistant result also and then to lose efficacy; As for turnover plate type, T-shaped sealing deodorization formula, if the living water use of floor drain discharge has the foreign material such as hair to block sealing block, can cause poorly sealed, odor-resistant result is also weathering, this two odour-proof floor drain is also very easily by mechanical impact simultaneously, the corrosion of turnover plate type meeting rotating plate shaft, and the axis of the piston of T-shaped sealing deodorization formula can adsorb dust and cause slip malfunctioning, in addition after T-shaped sealing deodorization formula also has magnet suction or spring force to weaken, sealing block cannot accurately return sealing drawback.
Also have now and be a kind ofly similar to the same self-closing deodorant floor drain core of plastic bag, main feature be have water by time, open under the Action of Gravity Field of water, anhydrous by time, utilize product self plasticity to close, thus play deodorization, prevent returning water effect.Floor drain core as shown in Figure 1, be made up of opening portion 1 ', diversion division 2 ', transition part 3 ' and closure 4 ', its opening portion 1 ' is cylindrical with diversion division 2 ', cross-sectional area is comparatively large, can ensure to descend water fast, but its transition part 3 ' is more flat with closure 4 ', cross-sectional area comparatively opening portion 1 ', diversion division 2 ' reduces greatly, when water flows to herein, flow also reduces relatively greatly, like this discharge capacity of whole floor drain core with regard to extreme influence.The drain gully pore size of floor drain differs, and when above-mentioned floor drain core is used in bore drain gully less than normal, although deodorization performance is improved, the displacement of floor drain can greatly reduce, and draining difficulty phenomenon easily occurs.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of displacement is large, good seal performance, be particularly useful for the reducing self-closing floor drain core of small-bore drain gully.
The technical scheme in the invention for solving the above technical problem is: this floor drain core comprises the opening portion of integrative-structure, diversion division, transition part and closure, its design feature be opening in the top of diversion division, closure is connected to the bottom of diversion division by transition part; The diameter of described transition part the widest part is greater than the diameter of opening portion and diversion division; The close out sheet that described closure is fit together by two panels forms.
Transition part described in the utility model is made up of the epimere integrally connected and hypomere, and epimere and hypomere are the gradual change circular arc tubular that upper end open is large, lower ending opening is little, and the diameter of epimere the widest part is greater than the diameter of opening portion and diversion division.
The width of closure described in the utility model is identical with the diameter of epimere the widest part.
The width of closure described in the utility model is greater than the diameter of epimere the widest part.
The utility model is provided with the evagination sealing block of some ring-types on the outer wall of described diversion division.
Closure described in the utility model is more than one.
The utility model compared with prior art, there is following beneficial effect: the diameter of this floor drain core transition part the widest part is greater than the diameter of opening portion and diversion division, the width of closure is more than or equal to transition part the widest part, the shape that overall formation is up-small and down-big, this addresses the problem in prior art because of large than transition part and closure of the cross-sectional area of opening portion and diversion division, the opening portion produced and diversion division flow are large, transition part and the little problem of closure flow, flow when further increasing draining and lower water speed; Especially be applicable to being arranged on small-bore drain gully, while improving deodorization performance, also increase displacement, to ensure that draining is unobstructed.
Accompanying drawing explanation
The front view of Fig. 1 prior art.
Fig. 2 is the front view of the utility model embodiment.
Fig. 3 is the lateral view of the utility model embodiment.
Detailed description of the invention
See Fig. 2 and Fig. 3, the material of the present embodiment is silica gel, and comprise the opening portion 1 of integrative-structure, diversion division 2, transition part 3 and closure 4, opening portion 1 is positioned at the top of diversion division 2, and closure 4 is connected to the bottom of diversion division 2 by transition part 3.The outer wall of diversion division 2 is provided with the evagination sealing block 5 of some ring-types.Transition part 3 is made up of the epimere 31 integrally connected and hypomere 32, and epimere 31 and hypomere 32 are the gradual change circular arc tubular that upper end open is large, lower ending opening is little, and the diameter of epimere 31 the widest part is greater than the diameter of opening portion 1 and diversion division 2.Closure 4 by two panels undulate and the close out sheet 6 fit together form, the width of closure 4 is identical with the diameter of epimere 31 the widest part.
During installation, floor drain core is placed in floor drain drain gully, fits tightly between evagination sealing block 5 and floor drain drain gully internal face.Anhydrous by time, two panels close out sheet 6 fits tightly, and closure 4 is in sealing state, and current cannot pass through.Have water by time, under the Action of Gravity Field of water, two panels close out sheet 6 is opened, and closure 4 is in open mode, and current pass through.
In the utility model, the width of closure 4 also can be greater than the diameter of epimere 31 the widest part; Closure 4 can be more than one, and closure 4 can be the shapes such as waveform, fold-line-shaped, linear.
The utility model also can adopt latex, rubber or other there is the plastic cement beformable body material of favorable elasticity.
The utility model also can be arranged on sewer pipe and use, as basin launching pipe, washing machine sewer pipe etc.
