Abstract
The utility model discloses a one-way gas-isolation device which aims to provide the one-way gas-isolation device having the advantages of simple structure, low cost and good gas-isolation effect. The utility model is a pipe fitting having the integrated structure made of elastic materials and comprises a connecting part (1), a transition part (2) and a tail (5), wherein the connecting part (1) forms a circular ring shape; the bottom end of the transition part (2) is provided with a crease line (a), and under the state of nature, the upper end of the transition part (2) is provided with a circular hole communicated with the circular hole of the connecting part (1), grades into a through hole of the lower end and is sealed to be in a shape of plane; under the state of nature the tail (5), the through hole of the tail (5) is sealed to be in the shape of plane. The utility model can be applied in the field of living drainage.
Description
Technical field
The utility model relates to a kind of unidirectional odour seal, relates in particular to a kind of unidirectional odour seal that is used for the trapping of sanitaryware drainage pipe.
Background technology
Outfall place at sanitaryware such as washing basins is provided with odour seal usually, returns in the inlet chamber that overflows by sanitaryware with pernicious gases such as foul smell isolated and that prevent from the drainage pipe to be produced.Existing odour seal has cup type, P type, U type, S type etc., mainly all is to form water seal by its bottom to realize the trapping function, and using maximum at present is the water seal of U type pipe.Rely on water seal to come the apparatus structure of trapping complicated, cost is higher, along with the lengthening of service time, owing to leak, reason water seals such as siphon, evaporation lost efficacy easily, thereby trapping poor effect.
So existing product has the following disadvantages: complex structure, higher, the trapping poor effect of cost.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes on the prior art, and a kind of simple in structure, with low cost, unidirectional odour seal that the trapping effect is good is provided.
The technical scheme that the utility model adopted is: the utility model is the integral structure pipe fitting of being made by elastomeric material, comprise connecting portion, transition part, afterbody, described connecting portion is circular, described transition part bottom is provided with the I crease line, described transition part upper end under nature has circular hole to communicate with described connecting portion circular hole and carries out the transition to the sealing of lower end through hole gradually and is plane, and described afterbody seals at the nature lower through-hole and is plane.
The utility model also comprises at least one pars intermedia, and described pars intermedia two ends connect mutually with described transition part, described afterbody respectively, and the junction of described pars intermedia and described afterbody is provided with the II crease line, and described pars intermedia is plane in the sealing of nature lower through-hole.
The utility model also comprises at least one steam vent, and described steam vent is arranged at described afterbody or described pars intermedia.
The utility model adopts rubber or silica gel or metal to make.
The beneficial effects of the utility model are: because the utility model is the integral structure pipe fitting of being made by elastomeric material, its volume is little, do not take space outerpace, the outfall place that only needs it to be installed in existing sanitaryware gets final product, do not influence the good looking appearance of sanitaryware, existing water seal can be installed, and cost saving is so the utility model is simple in structure, with low cost;
Because the utility model is made by elastomeric material, described transition part bottom is provided with the I crease line, described transition part upper end under nature has circular hole to communicate with described connecting portion circular hole and carries out the transition to the lower end through hole gradually to be sealed and is plane, described afterbody is plane in the sealing of nature lower through-hole, draining trapping process of the present utility model is as follows: under the situation that does not have water to discharge, the tension force of elastomeric material itself makes the no gap of described afterbody through hole sealing be plane, thereby sanitaryware outfall and the drainage pipe that is positioned under it are isolated by the utility model, and pernicious gas can not return in the inlet chamber that overflows by sanitaryware; When water was discharged, under the effect of current, the through hole enclosure portion of described transition part, described afterbody was opened successively, makes current enter drainage pipe smoothly, normal draining; After water had been arranged, the tension force of elastomeric material itself made described afterbody through hole seal no gap once more to be plane, isolated the Hui Yi of pernicious gas, so the utility model trapping effect is good;
Because the utility model also comprises at least one pars intermedia, described pars intermedia two ends connect mutually with described transition part, described afterbody respectively, the junction of described pars intermedia and described afterbody is provided with the II crease line, described pars intermedia is plane in the sealing of nature lower through-hole, described pars intermedia makes the utility model increase the trapping section one, so the trapping effect is better.

The specific embodiment
Embodiment one:
As Fig. 1, Fig. 2, shown in Figure 3, the utility model is the integral structure pipe fitting of being made by rubber, comprise connecting portion 1, transition part 2, a pars intermedia 3, four steam vents 4, afterbody 5, described connecting portion 1 is circular, described pars intermedia 3 two ends and described transition part 2, the junction of described afterbody 5 is respectively equipped with I crease line a, II crease line b, described pars intermedia 3, described afterbody 5 is plane in the sealing of nature lower through-hole, described transition part 2 upper end under nature has circular hole to communicate with described connecting portion 1 circular hole and carries out the transition to the lower end through hole gradually to be sealed and is plane, described steam vent 4 is arranged at described afterbody 5, be discharged into gutter so that may retain in the gas of described afterbody 5, make described afterbody 5 after having arranged water, can rely on the tension force of self material to be returned to the through hole sealing and be plane, that pernicious gas is drained into by the utility model is indoor and be unlikely, thereby better trapping, described transition part 2, described pars intermedia 3, the wall thickness of described afterbody 5 reduces successively, so that the utility model through hole after draining finishes can better seal the trapping better effects if from bottom to top.
The utility model is installed in the drainage pipe in the following way: being connected in the groove of head 6 and sewer pipe 7 down is fixed in the extruding of the annulus of described connecting portion 1 periphery, and described transition part 2, described pars intermedia 3, described afterbody 5 is sagging naturally stretches in the described sewer pipe 7.The utility model can be arranged separately in drainage pipe and not use water seal arrangement, also can on the basis of existing use water seal the utility model be installed, and does not need to change existing any structure, therefore installs, uses, changes conveniently.The number of certain pars intermedia described in the utility model 3 is not limited to one, and the number of described steam vent 4 also is not limited to four, and described steam vent 4 also can be arranged at described pars intermedia 3, and the utility model also can adopt other elastomeric materials such as silica gel or metal to make.
Embodiment two:
As Fig. 4, shown in Figure 5, present embodiment has saved described pars intermedia 3, II crease line b than embodiment one, and the number of described steam vent 4 is two, and all the other are with embodiment one.Present embodiment is simple structure form of the present utility model, can arrive the good effect of trapping effect fully.
The utility model can be applicable to the living drainage field.
Under the situation that does not break away from the present utility model thought, all application the utility model manuals and accompanying drawing content and the various equivalences of being done change, and all reason is with being contained in the claim scope of the present utility model.
